Factors related to utilization of dental services during pregnancy

OBJECTIVES: The purposes of this study were to investigate factors related to utilization of dental services during pregnancy and to assess the extent of mothers' knowledge regarding oral health during pregnancy and its effect on pregnancy outcomes. MATERIALS AND METHODS: Cross-sectional data were collected from 625 women using a structured questionnaire mailed to mothers who had given birth in Johnson County, Iowa from August 2001 to March 2002. The survey assessed knowledge, behaviours, attitudes toward dental care during pregnancy, and personal, demographic and pregnancy-related factors. Variables which showed associations in bivariate analysis (p< or =0.1) were considered as candidates for building logistic regression models separately by domain (demographics, dental health care behaviours, lifestyle, financial variables, pregnancy-related variables, and knowledge of the possible association between oral health and pregnancy). Significant domain-specific regression results (p< or =0.05) were used to develop a final model using forward stepwise logistic regression analyses. RESULTS: The overall response rate was 69%. Dental visits during pregnancy were reported by 49% of respondents. Forty-three percent were aware of the possible connection between oral health and pregnancy outcomes. In the final logistic regression analysis, factors significantly associated with reporting dental visits during pregnancy were: (1) personal factors (being married, greater frequency of visiting the dentist when not pregnant and use of inter-proximal cleaning aids); (2) financial factors (dental insurance); and (3) knowledge of the possible connection between oral health and pregnancy outcomes. CONCLUSIONS: There was limited knowledge of the possible relationships between oral health and pregnancy outcomes in a fairly homogeneous population of women who were of relatively high socioeconomic standing. This study suggests that better education of the importance of dental care before and during pregnancy is needed.     

Children's use of dental services: influence of maternal dental anxiety, attendance pattern, and perception of children's quality of life

OBJECTIVES?: The purpose of the study was to investigate the influence of a child's clinical condition; maternal characteristics such as dental anxiety and dental visit pattern; socioeconomic conditions; and maternal perception of the child's oral health-related quality of life (OHRQoL) on a child's use of dental care services. METHODS?: A cross-sectional study of 608 mother-child dyads was conducted during the Children's Immunization Campaign in Pelotas, Brazil. Mothers answered a questionnaire regarding their use of dental services, dental anxiety (Dental Anxiety Scale), socioeconomic status, and perception of their children's OHRQoL (the Early Childhood Oral Health Impact Scale). Clinical examination of the children was performed to assess dental caries (dmf-t). Associations between the above-mentioned factors and child use of dental services were assessed using Poisson regression models (prevalence ratio [PR]; 95% CI; P?≤?0.05). RESULTS?: The majority of children (79.3%) had never had a dental appointment and of the children who had visited a dentist, 55 (43.65%) presented with untreated dental caries at the time of examination. More than half the mothers (60.2%) did not visit a dentist regularly. In the final model, low schooling level of mothers (PR, 0.64) and irregular visits to a dentist by the mother (PR, 0.48) were factors because of which a child did not have a dental appointment. Children who had experienced pain (PR, 1.56), those who had poor OHRQoL (PR, 1.49), and older children (PR, 2.14) visited a dentist with higher frequency. CONCLUSIONS?: Use of dental care services by preschool children was low, and treatment was neglected even among children who had visited a dentist. Children of mothers with low schooling level who do not visit a dentist regularly were at greater risk of not receiving dental care. Maternal perception of their child's oral health motivated visits to the dentist.     

The influence of the volume of dental treatment on change in self‐reported oral health

Objectives: To find an association between self‐reported change in oral health and dental treatment volume. Methods: Baseline data were obtained from the Tasmanian component of the National Survey of Adult Oral Health 2004‐06 and 12‐month follow‐up data from service use logbooks and mail self‐complete questionnaires. The global oral health transition statement indicated change in oral health. Many putative confounders were analyzed and Poisson regression with robust variance estimation was used to calculate the prevalence ratios and 95 percent confidence intervals for bivariate‐ and multivariate‐adjusted relationships. Results: One‐eighth (12.4 percent) of the participants reported that their oral health had improved. Over half visited a dentist (n = 176, 52.6 percent), of whom 105 received less than six dental services and 71 received six or more dental services. Baseline oral disease (P = 0.01), having a treatment need (P < 0.01), usually visiting a dentist for a problem (P < 0.05), and having a lot of difficulty paying a $100 dental bill (P = 0.01) were significantly associated with the same or worsening oral health. The regression model indicated that having six or more dental services (P < 0.01) was significantly associated with improvement in oral health, indicating a threshold effect. Usually visiting a dentist for a check‐up was significantly associated with improvement in oral health (P < 0.01). Conclusion: Having six or more dental services was significantly associated with a greater self‐reported improvement in oral health than having less than six dental services. The greater prevalence ratios with increasing dental service volume suggested a threshold effect.     

Dental knowledge, attitudes towards oral health care and utilization of dental services among male industrial workers with or without an employer-provided dental benefit scheme

Abstract In industrialized countries various dental benefit schemes have been implemented to improve the utilization of dental services, though few studies have demonstrated that effect. Prior to a comprehensive clinical study in southern Finland, a postal questionnaire survey of male industrial workers (age 38–65 yrs) was conducted to investigate knowledge and attitudes concerning oral health care and whether access to an employer-provided dental benefit scheme was associated with the utilization of dental services. The response rate was 81% (n=325) in the subsidized group and 69% (n=174) in the control group. In both groups, 60% of the subjects had had their last dental visit within a year but 91% of the subsidized workers compared to 79% of the controls had visited a dentist in the past two years (p<0.001). The subjects had similar attitudes towards the importance of regular dental care and its implications for dental and general health. Subsidization explained the disparity in the current dental visiting pattern between the groups better than the possibility of using working hours for dental visits. Backward stepwise logistic regression revealed that the probability of a dental visit within the past two years was positively associated with access to an employer-provided dental benefit scheme, tooth brushing to maintain dental health, and number of teeth, and negatively associated with number of carious teeth. Our results demonstrate a positive impact of subsidization on the utilization of dental services.     

Self-reported oral health, oral hygiene habits, and dental attendance of pregnant women in Kuwait

OBJECTIVES: The aim of this study was to describe self-reported oral health, oral hygiene habits, and frequency of visits to a dentist among pregnant women in Kuwait. MATERIAL AND METHODS: A cross-sectional study with an anonymous structured questionnaire was distributed among 650 pregnant women during May-June 2003, when they were admitted to the maternity ward at the largest government maternity hospital in Kuwait City. The response rate was 93% (n=603). RESULTS: Every fourth respondent was in her first pregnancy, while 36% already had three or more children. Every fifth woman felt that her oral health was poor, and one-third of the women believed that they had periodontal problems currently. About two-thirds of the women were brushing more than once a day and almost all (94%) at least once a day. Over the previous 6 months, 40% had experienced dental pain. Half of the women had visited a dentist during pregnancy, mostly for dental pain. Most of the women had received no instructions concerning oral health care during their pregnancy. CONCLUSIONS: A large proportion of the pregnant women in this study had oral health problems; however, half of the women had not seen a dentist during their pregnancy.     

Preference for dentist's home visits among older people

Komulainen K, Ylöstalo P, Syrjälä A‐M, Ruoppi P, Knuuttila M, Sulkava R, Hartikainen S. Preference for dentist’s home visits among older people. Community Dent Oral Epidemiol 2012; 40: 89–95. © 2011 John Wiley & Sons A/S Abstract – Objectives: To investigate factors associated with older people’s preference for a dentist’s home visit. Methods: This is a report on 321 home‐dwelling participants (mean age 81.6) in the population‐based Geriatric Multidisciplinary Strategy for Good Care of the Elderly (GeMS) study, conducted in 2004–2005 in the city of Kuopio in eastern Finland. The information about sociodemographic and general health‐related factors and the use of social and health services was collected by two study nurses using a structured interview. Each study subject was given a clinical oral examination and an interview about oral health and the use of dental health care services by one of two dentists. Logistic regression models were used to estimate odds ratios (OR) and 95% confidence intervals (CI). Results: Of the study subjects, 25.9% preferred a dentist’s home visit. The preference for choosing a dentist’s home visit was associated with a low score (≤24) in the Mini‐Mental State Examination, OR 6.1 (CI: 2.9–13.6), and a low score (<8) on the scale of Instrumental Activities of Daily Living, OR 8.0 (CI: 3.6–18.6). It was also associated with living alone, OR 5.9 (CI: 2.7–13.0), and high use of home care services, OR 9.3 (CI: 4.6–19.0). Conclusions: The findings of this study emphasize the need to organize dentists’ home visits in order to increase equality in the use of dental health care services among the older people with disabilities.     

Predictors of dental care utilization among working poor Canadians

Abstract – Objective: This study used the Gelberg–Andersen Behavioral Model for Vulnerable Populations to identify predictors of dental care utilization by working poor Canadians. Methods: A cross‐sectional stratified sampling study design and telephone survey methodology was used to collect data from a nationally representative sample of 1049 working poor individuals aged 18 to 64 years. Working poor persons worked ≥20 h a week, were not full‐time students and had annual family incomes <$34 300. A pretested questionnaire included sociodemographic items, self‐reported oral health measures and two dental care utilization outcomes: time since their last dental visit and the usual reason for dental visits. Results: Hierarchical stepwise logistic analyses identified independent predictors associated with visiting the dentist >1 year ago: male gender (OR = 1.63; P = 0.005), aged 25–34 years (OR = 2.05; P = 0.02), paying for dental care with cash or credit (OR = 2.31; P < 0.001), past welfare recipients (OR = 1.65; P = 0.03), <21 teeth (OR = 4.23; P < 0.001) and having a perceived need for dental treatment (OR=2.78; P < 0.001). Sacrificing goods or services to pay for dental treatment was associated with visiting the dentist within the past year. The predictors of visiting the dentist only when in pain/trouble were lone parent status (OR = 4.04; P < 0.001), immigrant status (OR = 1.72; P = 0.006), paying for dental care with cash or credit (OR = 2.71; P < 0.001), a history of an inability to afford dental care (OR = 1.62; P = 0.01), a satisfactory/poor/very poor self‐rated oral health (OR = 2.10; P < 0.001), number of teeth <21 (OR = 2.58; P < 0.001) and having a perceived need for dental treatment (OR = 2.99; P < 0.001). Conclusions: This study identified predisposing and enabling vulnerabilities that jeopardize the dental care‐seeking practices of working poor persons. Dental care utilization was associated with relinquishing spending on other goods and services, which suggests that dental care utilization is a competing financial demand for economically constrained adults.     

Survey of medical doctors' attitudes and knowledge of the association between oral health and pregnancy outcomes

Abstract: Objectives: The study was designed to assess the views and knowledge of healthcare providers in general medicine and other specialties on the association between oral health and pregnancy outcomes. Material and Methods: Two hundred and fifty physicians practicing in northern Jordan hospitals and healthcare centers were asked to complete a questionnaire. Completed questionnaires with the answers were returned completed by 197 participants (response rate was 79%). Results: The majority of the physicians (81%) agreed that pregnancy increases the tendency to have gingival inflammation. However, 88% of doctors advised delay dental treatment until after pregnancy. Only half (54%) thought that tooth and gums problem can affect the outcomes of pregnancy. Moreover, approximately 50% agreed with the possible association between oral health and pregnancy outcomes. Altogether, 52% agreed with the statement ‘a tooth for a baby’ and 57% believed that calcium will be drawn by the developing baby. If asked to advise patient to visit dentist during pregnancy, 50% said they would do so. Moreover, the majority (68%) did not advise women planning to become pregnant to include a periodontal evaluation as part of their prenatal care. About 32% felt that periodontal disease can be treated safely during pregnancy with a procedure called scaling and root planning. Reading the information in a book, magazine or pamphlet was useful and reliable information about preterm births and periodontal disease. Physicians do not routinely advise their patient to seek dental care during pregnancy. General practitioners were less informed about oral health practices on pregnant women. Issues on training need to be addressed. A public health campaign is required to educate healthcare providers to encourage pregnant women on the need for a regular dental check‐up during and prior to attempting pregnancy. Conclusion: There is a need to educate healthcare personnel further about oral health and pregnancy outcomes.     

The association between low-socioeconomic status mother's Sense of Coherence and their child's utilization of dental care

da Silva AN, Mendonça MH, Vettore MV. The association between low‐socioeconomic status mother’s Sense of Coherence and their child’s utilization of dental care. Community Dent Oral Epidemiol 2011; 39: 115–126. © 2010 John Wiley & Sons A/S Abstract – Objectives: The objective of this study was to investigate the relationship of low‐socioeconomic status mother’s Sense of Coherence (SOC) and their child’s utilization of dental care services in a city of Southeast Brazil. Methods: A cross‐sectional study was conducted on a sample of 190 schoolchildren aged 11–12 and their mothers in Sao João de Meriti‐RJ, Southeast Brazil. The outcome variables were children’s use of dental care services and visiting dentists mainly for check‐ups. Demographic and socioeconomic characteristics and data regarding children’s dental care use were collected through interviews with mothers. Children’s oral health‐related behaviours as well as dental status (DMFS index), dental pain, Visible Dental Plaque and Bleeding on Probing Index were registered. Mother’s SOC was assessed through the validated short version (13‐item) of Antonovsky’s scale. Multiple logistic regression was used in the data analysis. Results: Of the mothers, 81.1% reported on their child’s utilization of dental care services. Of them, 42.9% considered check‐ups as the main reason for taking their children to dental services. Children whose mothers had higher levels of SOC were more likely to utilize dental care services (OR = 2.08 95%CI = 1.17–3.64) and visit a dentist mainly for check‐ups (except for dental treatment) (OR = 2.02 95%CI = 1.06–3.81) than those whose mothers had lower levels of SOC. These findings were adjusted for socioeconomic status, children’s oral health‐related behaviours and oral health measures. Conclusions: Mother’s SOC was a psychosocial factor associated with their child’s pattern of use of dental care services in low‐socioeconomic status families.     

Dental Care Visits among Dentate Adults with Diabetes and Periodontitis

Objectives: Two national surveys have shown that dentate adults with diabetes are less likely to visit a dentist than are those without diabetes; one survey showed this association only among women. We hypothesize that periodontal health among those with diabetes could explain this disparity. This report investigates the influence of periodontitis on the association between diabetes and dental care visits. It also tests whether disparities are limited to women. Methods: Data from the 1999‐2004 National Health and Nutrition Examination Survey were used. Covariates included age, sex, race/ethnicity, poverty status, education level, dental insurance, and periodontitis status. Weighted analyses were limited to dentate adults aged ≥25 years. Results: Overall, 56.8 percent of dentate adults with diabetes reported having a dental care visit in the preceding year compared with 64.7 percent for those without diabetes. In a multivariable model, diabetes status was significantly associated with having a dental care visit, independent of periodontitis status and covariates. Neither periodontitis status nor sex served as effect modifiers for the association between diabetes status and dental care visits. Conclusions: These data revealed that dental care visits for dentate adults with diabetes were unrelated to their periodontal health, suggesting that fear of periodontal therapy did not influence visit patterns. These data also showed that dental care visit disparities existed for all adults with diabetes, not just women. Future research should investigate whether factors that are indirectly related to diabetes status, such as competing costs, attitudes, and knowledge, are influencing dental care visit patterns among dentate adults with diabetes.     

Changing knowledge and beliefs through an oral health pregnancy message

Objectives: Pregnancy can be a critical and important period in which to intervene to improve oral health in both the mother and her child. This study examined an online approach for promoting awareness of oral health messages targeted at pregnant women, and whether this type of health messaging impacts oral health knowledge and beliefs. Methods: The study was conducted in three parts: production and pilot testing of a brief commercial, Web site/commercial launch and testing, and dissemination and monitoring of the commercial on a video‐sharing site. The brief commercial and pre‐ and postsurveys were produced and pilot tested among a convenience sample of pregnant women (n = 13). The revised commercial and surveys were launched on a newly created Web site and monitored for activity. After 2 months, the commercial was uploaded to a popular video‐sharing Web site. Results: Fifty‐five individuals completed both the pre‐ and postsurveys after the Web site was launched. No one responded 100 percent correctly on the presurvey; 77.4 percent responded correctly about dental visits during pregnancy, 66.0 percent about cavity prevention, and 50.9 percent about transmission of bacteria by saliva. Most respondents recalled the correct information on the posttest; 100 percent or close to 100 percent accurately responded about visiting the dentist during pregnancy and preventing cavities, while 79.2 percent responded correctly to the transmission question. Conclusion: Social media can effectively provide dental health messages during pregnancy. This approach can play an important role in increasing awareness and improving oral health of both mother and child.     

Oral health care utilization by US rural residents,National Health Interview Survey 1999

OBJECTIVE: To compare the dental care utilization practices of rural and urban residents in the United States. METHODS: Data on dental care utilization from the 1999 National Health Interview Survey for persons 2 years of age and older (n=42, 139) were analyzed by rural/urban status. Percentages and 95 percent confidence intervals were calculated to produce national estimates for having had a visit in the past year, the number of visits, reasons given for last dental visit and for not visiting a dentist, unmet dental needs, and private dental insurance. RESULTS: Rural residents were more likely to report that their last dental visit was because something was "bothering or hurting" (23.3% vs 17.6%) and that they had unmet dental needs (10.1% vs 7.5%). Urban residents were more likely to report having a dental visit in the past year (57.7% vs 66.5%) and having private dental insurance (32.7% vs 37.2%), compared to rural residents. There were no significant differences in most reasons given for not visiting the dentist between rural and urban respondents. CONCLUSION: Dental care utilization characteristics differ between rural and urban residents in the United States, with rural residents tending to underutilize dental care.     

Access to oral health services for urban low-income Latino children: social ecological influences

Objectives: Using an ecological conceptual model, this study examined the social context, structural, and behavioral factors within an immigrant community that contribute to increased access and use of oral health services by Latino children. The predictors of health service use at the level of the individual, the family, the provider, and the health service system were studied for their effects on the initiation of care, continuity of care, and frequency of planned visits. Methods: In‐depth face‐to‐face interviews were conducted with 320 Latino mothers regarding their use of oral health services for 4‐8‐year‐old children [Mexican (n = 221), Puerto Rican (n = 69), and Central and South American (n = 30)]. Outcome measures of dental care utilization were early age at initiation of care, continuity of care, and frequency of planned dental visits. Results: Regular planned dental visits were significantly related to the structural variables of household income and provider availability. The initiation of dental care was related to the mother's beliefs about the value of early preventive dental care. Mothers were more likely to continue care if they believed that the purpose was to keep the child's teeth healthy and had satisfactory communication with the dentist. Conclusions: Identifying the structural and behavioral factors that increase the likelihood of the use of oral health services can provide the basis for developing effective interventions specific to Latino children at the neighborhood level. The study findings can be also used for designing culturally appropriate oral health promotion programs and provider coordination of care.     

Income, dental insurance coverage, and financial barriers to dental care among Canadian adults

Objectives: To explore the issue of affordability in dental care by assessing associations between income, dental insurance, and financial barriers to dental care in Canadian adults. Methods: Data were collection from a national sample of adults 18 years and over using a telephone interview survey based on random digit dialing. Questions were asked about household income and dental insurance coverage along with three questions concerning cost barriers to accessing dental care. These were: “In the past three years . . . has the cost of dental care been a financial burden to you? . . . have you delayed or avoided going to a dentist because of the cost? . . . have you been unable to have all of the treatment recommended by your dentist because of the cost?” Results: The survey was completed by 2,027 people, over half of which (56.0%) were covered by private dental insurance and 4.9 percent by public dental programs. The remainder, 39.1 percent, paid for dental care out‐of‐pocket. Only 19.3 percent of the lowest income group had private coverage compared with 80.5 percent of the highest income group (P < 0.001). Half (48.2%) responded positively to at least one of the three questions concerning cost barriers, and 14.8 percent responded positively to all three. Low income subjects (P < 0.001) and those without dental insurance (P < 0.001) were most likely to report financial barriers to care. While private dental insurance reduced financial barriers to dental care, it did not entirely eliminate it, particularly for those with low incomes. Those reporting such barriers visited the dentist less frequently and had poorer oral health outcomes after controlling for the effects of income and insurance coverage. Conclusions: Canadian adults report financial barriers to dental care, especially those of low income. These barriers appear to have negative effects with respect to dental visiting and oral health outcomes. For policy, appropriateness will be key, as clarity needs to be established in terms of what constitutes actual need, and thus which dental services can then be considered a public health response to affordability.     

Dental utilization among Hispanic adults in agricultural worker families in California's Central Valley

Objective: To examine past‐year dental visits among underserved, Hispanic farmworker families using the Andersen Behavioral Model of Health Services Utilization, which posits that predisposing, enabling, and need factors influence care‐seeking behavior. Methods: Oral health survey and clinical data were collected in 2006‐2007 from families in Mendota, California (Fresno County) as part of a larger, population‐based study. Generalized estimating equation logit regression assessed effects of factors on having a dental visit among adults (N = 326). Predisposing variables included sociodemographic characteristics, days worked in agriculture, self‐rated health status, and dental beliefs. Enabling factors included resources to obtain services (dental insurance, income, acculturation level, regular dental care source). Need measures included perceived need for care and reported symptoms, along with clinically determined untreated caries and bleeding on probing. Results: Only 34% of adults had a past‐year dental visit, despite 44% reporting a regular dental care source. Most (66%) lacked dental insurance, and nearly half (46%) had untreated caries. Most (86%) perceived having current needs, and on average, reported a mean of 4.2 dental symptoms (of 12 queried). Regression analyses indicated those with more symptoms were less likely to have a past‐year dental visit. Those who would ask a dentist for advice and had a regular dental care source were more likely to have a past‐year dental visit. Conclusions: The final model included predisposing, enabling, and need factors. Despite low utilization and prevalent symptoms, having a regular source of care helps break this pattern and should be facilitated.     

Mediators between education and dental pain: a cross‐sectional study to assess the role of dental services utilization

This study tested whether the pattern of dental services utilization and the reason for the last dental visit mediate the association between educational attainment and dental pain. This is a cross‐sectional analysis (n = 1099) based on data from a prospective cohort study in adults, southern Brazil. The mediating effects were assessed by including interaction terms in logistic regression models and by the KHB method, which estimated the direct, mediated, and total effects of education on dental pain. The prevalence of dental pain was 17.5%. Individuals with less than 12 yr of study who visited the dentist to solve dental problems had a 20% higher odds of reporting dental pain than those with 12 or more years of study, who sought the dentist for preventive reasons. Dental services should also focus on preventive measures, especially if less‐educated individuals visit the dentist only to treat problems; this may help reduce the frequency of negative oral health outcomes, including dental pain.     

Association between routine visits for dental checkup and self-perceived oral health in an adult population in Rio de Janeiro: the Pró-Saúde Study

OBJECTIVE: To investigate the association between routine visits for dental checkup and self-perceived oral health. METHODS: Cross-sectional data from a study of university employees in Rio de Janeiro - The Pró-Saúde Study. Self-perceived oral health and the reported pattern and frequency of visits to the dentist were obtained through a multidimensional self-administered questionnaire. RESULTS: Data were obtained from 3252 participants. When compared with individuals who reported self-perceived oral health as good ('very good', 'good' or 'fair') individuals who reported self-perceived oral health as bad ('bad' or 'very bad') were significantly more likely to be older, male, less educated, poorer; they also reported more frequently to have lost more teeth and not visiting the dentist for routine dental 'checkup'. Among those who reported visiting for dental checks at least annually, 3% reported bad oral health, as opposed to 15% among those who reported visiting the dentist only when in trouble. Compared with those who reported visiting the dentist at least annually, odds ratio of bad oral health was 3.9 (95% CI, 2.68-5.67) for subjects who reported visiting only when in trouble, 2.6 (95% CI, 1.51-4.62) who reported visiting for dental checks less frequently than once every 2 years, and 1.4 (95% CI, 0.77-2.52) for subjects who reported visiting for dental checks once every 2 years, after controlling for sex, age, education, income and tooth loss. CONCLUSIONS: Not visiting the dentist for a routine dental check increased the chance of reporting one's own oral health as bad. In any case, the habit of visiting for dental 'checkup, once per year or once every 2 years was associated with nearly all the individuals perceiving his/her oral health positively. However, in order to gather more solid scientific data to guide public policies it is necessary to perform longitudinal studies, especially experiments in different populations focused mainly on the socioeconomic characteristics and dental clinical conditions.     

Why is there heterogeneity in the effect of dental checkups? Assessing cohort effect

Celeste RK, Nadanovsky P. Why is there heterogeneity in the effect of dental checkups? Assessing cohort effect. Community Dent Oral Epidemiol 2010; 38: 191–196. © 2010 John Wiley & Sons A/S Abstract – Objectives: To evaluate age as a potential effect modifier of the relation between frequency of dental check‐up and oral health. Methods: Data from a Brazilian oral health survey carried out in 2002–2003 was obtained for three age groups: 15–19‐year‐old (n = 16411); 35–44‐year‐old (n = 13 269); and 65–74‐year‐old (n = 5 300). Individuals were examined by dentists and followed to an interview. Self‐reported time since last dental visit was measured as ‘less than 1 year’; ‘from 1 to 2 years’; ‘3 or more years’ or ‘never’. Outcomes modelled with negative binomial regression were DMFT index and DT, MT and FT. Results: Visiting the dentist more recently was associated with fewer teeth with untreated dental caries (DT) and more teeth with fillings (FT) across all age groups. Among the 15–19‐year‐old, the longer the time since last visit the lower the DMFT and MT. On the other hand, among the 35–44 and the 65–74‐year‐old the longer the time since last dental visit the higher the DMFT and MT, though this trend reverted in the ‘never visited’ group. Conclusions: Age modified the effect of dental visits on DMFT and MT. In younger cohorts, the low frequency of dental check‐up among those with good oral health may reflect the fact that these young people do not feel they need to go to the dentist very often, while in older cohorts, the current low frequency of dental check‐up associated with bad oral health may be a reflection of a lifetime of high disease incidence coupled with access barriers. Questions regarding the time and frequency of dental visits may capture different dimensions of utilization of dental services, and so pooled estimates are not appropriate. Our results may help explaining contrasting results in previously published studies.     

Oral health and oral diseases in pregnancy: a multicentre survey of Italian postpartum women

Background

The aim of this study was to explore the oral hygiene practices and oral health status of Italian postpartum women.

Methods

A self‐administered questionnaire assessed socio‐demographic information, oral hygiene habits and frequency of dental visits. All women received a thorough oral examination within five days after delivery. Logistic regression models were used to estimate odds ratios and 95% confidence intervals for exposures of interest and the presence of ‘severe’ periodontitis.

Results

Seven hundred and fifty women participated in the study; 99.1% brushed their teeth everyday and 59.9% visited the dentist annually. The mean frequency of sites with bleeding on probing was 16.1% and the median clinical attachment level was 2.1 mm. The mean caries experience score (DMFT) was 8. Severe periodontal disease was present in 21.9% of individuals. Patients who reported visiting a dentist only when in pain and women with three dental caries or more were significantly more likely to have periodontitis (OR: 1.6; 95% CI: 1.1–2.2; p < 0.05 and OR: 2.3; 95% CI: 1.5–3.5; p < 0.01, respectively).

Conclusions

Given the possible association between maternal and infant oral health, and between periodontal infection and general health, antenatal care providers should collaborate with dentists to encourage all pregnant women to comply with the oral health professionals' recommendations regarding appropriate dental brushing techniques and the importance of dental visits.
