Changes in oral health-related quality of life (OHRQoL) related to long-term utilization of dental care among older people

Objective: To examine whether long-term utilization of dental care, treatment with fillings and crowns and persistent tooth loss between age 50 and 65 years associate with subsequent changes in OHRQoL from age 65 to 70 years.

Method: In 1992, a census of 50-year-olds received invitation to participate in a questionnaire survey. Of 6346 respondents, 3585 completed follow-ups in 1997, 2002, 2007 and 2012. OHRQoL was measured using the Oral Impacts on Daily Performances (OIDP) inventory.

Results: Around 70.4%, 11.2% and 18.4% confirmed respectively, no change, worsening, and improvement in OIDP scores between age 65 and 70 years. Compared to those being permanent non-routine dental attenders, ORs of improving and worsening of OIDP were respectively, 0.4 and 0.6 if being a permanent routine dental attender. ORs for improving OIDP was 1.6 if reporting persistent specialist attendance and 2.5 if having received crowns and fillings. Participants with permanent tooth loss were most likely to both worsen and improve OIDP.

Conclusion: Long-term routine dental attendance and permanent tooth loss occurred as predictors simultaneously for improvement and worsening of OIDP. Accumulation of advantages and disadvantages throughout the life-course increases and decreases the probability of improvement and worsening in OIDP among older people in Sweden.     

A multi‐country comparison of reasons for dental non‐attendance

The purpose of this study was to describe differences across countries with respect to the reasons for dental non‐attendance by Europeans currently 50 yr of age and older. The analyses were based on retrospective life‐history data from the Survey of Health, Ageing, and Retirement in Europe and included information on various reasons why respondents from 13 European countries had never had regular dental visits in their lifetime. A series of logistic regression models was estimated to identify reasons for dental non‐attendance across different welfare‐state regimes. The highest proportion of respondents without any regular dental attendance throughout their lifetime was found for the Southern welfare‐state regime, followed by the Eastern, the Bismarckian, and the Scandinavian welfare‐state regimes. Factors such as patients’ perception that regular dental treatment is ‘not necessary’ or ‘not usual’ appear to be the predominant reason for non‐attendance in all welfare‐state regimes. The health system‐level factor ‘no place to receive this type of care close to home’ and the perception of regular dental treatment as ‘not necessary’ were more often referred to within the Southern, Eastern, and Bismarckian welfare‐state regimes than in Scandinavia. This could be relevant information for health‐care decision makers in order to prioritize interventions towards increasing rates of regular dental attendance.     

Income gradients in oral health according to child age

This study aimed to confirm whether the well‐known income disparities in oral health seen over the life course are indeed absent in 9‐ to 11‐yr‐old children, and to explore the role of access to dental care in explaining the age‐profile of the income gradient in child oral health. We used data from the 2007 United States National Survey of Children's Health. Income gradients in parental reports of children's decayed teeth or cavities, toothache, broken teeth, bleeding gums, and fair/poor condition of teeth were assessed in stratified analyses according to age of child (1–5, 6–8, 9–11, 12–14, and 15–17 yr), using survey logistic regression to control for family‐, parental‐, and child‐level covariates. Health insurance status and use of preventive dental care were the indicators for children's access to dental care. The adjusted ORs for the effect of family income on having decayed teeth or cavities, toothache, and fair/poor condition of teeth were not significant in 9‐ to 11‐yr‐old children. Different age‐patterns were found for broken teeth and bleeding gums. The attenuation of the income gradients in having decayed teeth or cavities, toothache, and fair/poor condition of teeth, previously seen in 9‐ to 11‐yr‐old children, was also seen in 15‐ to 17‐, 12‐ to 14‐, and 6‐ to 8‐yr‐old children, respectively, after controlling for children's access to dental care. This study supports the attenuation of income inequalities in oral health in 9‐ to 11‐yr‐old children. Access to dental care could attenuate income gradients in oral health in other age groups.     

Changes in dental attitude and behavior among Dutch adults wearing complete dentures

Abstract In 1992 a follow-up on the Dutch National Dental Survey of 1986 (DNDS) was performed. The main objective was to detect and analyze changes in oral self care, dental attendance, and oral health status. This paper will focus on the DNDS adults wearing complete dentures. Changes over a 6-yr period will be presented of: dental attendance, denture satisfaction and wearing of the complete dentures, and denture treatments. A postal questionnaire was used: 232 persons (64%) participated in the study. Analysis of Variance (ANOVA) was used to study the effect of dental and social variables on observed changes since 1986. Risk ratios (RR) were computed to clarify the actual effects of these variables. With respect to dental attendance, a shift towards visits for denture check-ups was found, thought to reflect the respondents' concern for their complete dentures (RR=1.6). A small shift towards more visits because of denture problems was found. This was attributed to denture treatments that had taken place between 1986 and 1992 (RR=2.8). With respect to changes in denture satisfaction, no influence of denture treatments could be noted, but a relation was found with a variable indicating the imperfection of the complete dentures as felt by the respondents (RR=2.8). In 31% of the respondents some denture treatment had been performed since 1986. No objective dental criteria of complete dentures and denture bearing areas had influenced these denture treatment decisions, but only respondents' subjective criteria (RR= 1.9–2.9).     

Ingredients in dentifrices and their effect on plaque, gingivitis and mutans streptococci

Objective: The aim of this study was to investigate attitudes and opinions of old, independently living people about their oral health and how it has affected them through life. Material and methods: A random selection of 12 individuals was made in a group of 79 individuals who earlier participated in a study about self‐reported oral health. The average age was 78.4 years. An interview guide was used as support to focus on oral health. The respondents themselves decided what was important within the topics. The respondents were encouraged to speak freely about their childhood, family, social relations, memories from early dental care, general health situation, experience from health care, life and their future. The interviews were recorded and extended from 60 to 90 min. All of them were transcribed and analysed with phenomenological method inspired by Giogi. The analysis was made by two researchers independently. After 11 interviews, no new information was found; similar opinions, answers and stories recurred. Results: Seven of 11 respondents were born and grown up in the countryside and had moved to Stockholm in the forties. Awareness about dental care was generally low. Many of them have terrible memories from early dental visits, and the dentist was authoritarian and rough. Many had no memories of brushing their teeth as a child. Most of the respondents went to dentists as adults and when they could afford to pay by themselves. After retirement, all have continuous dental care and have visited a dental hygienist during the last 20 years. Nine of 11 have regular contact with a dental hygienist. Most of them are satisfied with their oral health and want to continue being clean and healthy in the mouth. Conclusions: Most of the respondents experienced an improved oral health, information and instructions from the dental hygienist have affected their self‐care. Many tell that they have become more aware and carry out the oral hygiene more carefully after retirement. All of them experience that oral health affects the quality of life.     

The influence of dental attendance on change in oral health-related quality of life

Crocombe LA, Brennan DS, Slade GD. The influence of dental attendance on change in oral health–related quality of life. Community Dent Oral Epidemiol 2012; 40: 53–63. © 2011 John Wiley & Sons A/S Abstract – Background: Few longitudinal studies have investigated the association between dental attendance and oral health–related quality of life (OHRQoL). These studies were limited to older adults, or to study participants with an oral disadvantage and did not assess if dental attendance had a different effect on OHRQoL for different people. Objective: This project was designed to test whether routine dental attendance improved the OHRQoL of survey participants and whether any patient factors influenced the effect of dental attendance on change in OHRQoL. Methods: Collection instruments of a service use log book and a 12 month follow‐up mail self‐complete questionnaire were added to the Tasmanian component of the National Survey of Adult Oral Health 2004/06. The dependent variable was change in OHIP‐14 severity and the independent variable was dental attendance. Many putative confounders/effect modifiers were analysed in bivariate, stratified and three‐model multivariate analyses. These included indicators of treatment need, sociodemographic characteristics, socioeconomic status, pattern of dental attendance and access to dental care. Results: None of the putative confounders were associated with both dental attendance and the change in mean OHIP‐14 severity. The only statistically significant interaction for change in OHIP‐14 severity was observed for dental attendance by residential location (P < 0.01). In multivariate analysis, there was a statistically significant association of dental attendance with change in mean OHIP‐14 severity. It also showed that the difference in association of attendance between Hobart, the capital city of Tasmania, and other places was statistically significant based on the interaction between residential location and attendance (P < 0.05). Conclusion: The effect of dental attendance on OHRQoL was influenced by a patient's residential location.     

High educational attainment moderates the association between dental health‐care supply and utilization in Europe

In line with the theory of supplier‐induced demand, an increased physician density often goes along with a higher utilization of medical services, including dental services. This study aimed to assess whether dentist density and self‐employment are related to dental care use, and whether these relationships are moderated by patients' educational attainment. We used data from the Survey of Health, Ageing, and Retirement in Europe (SHARE) from over 20,000 respondents, 50 + yr of age, in 13 countries. We conducted multilevel logistic regressions with probability and type of dental treatment on individual education, country‐specific dentist density, and dentist remuneration, and their cross‐level interaction. Patients with a high educational level were more likely to report a dentist visit (OR = 2.1, 95% CI: 1.912–2.305) and to receive preventive care (OR = 1.9, 95% CI: 1.697–2.043) than those with a low educational level (reference category). Cross‐level interaction effects indicated that high dentist density decreases dental care utilization differences between patients with high (OR = 0.996, 95% CI: 0.993–0.999), medium (OR = 0.995, 95% CI: 0.991–0.999), and low education levels. This was also true for prevention use (OR = 0.996, 95% CI: 0.992–0.999 for patients with a high education level, and OR = 0.996, 95% CI: 0.993–1.000 for patients with a medium education level). The findings suggest that although dentist density is positively associated with dental care utilization, patients have differing susceptibilities to dental care supply.     

Students' attitudes and knowledge on pain and pain management in paediatric dentistry—An observational study

Introduction

The dental and dental hygienist educational programs prepare students with knowledge on children's prophylactic pain treatment and pain management. Observing the students' understanding could help educational efforts to be more student oriented. The aim was to evaluate dental and dental hygienist students' knowledge and attitudes on pain prevention and pain management in children and adolescents, applying a multidimensional questionnaire previously used on general dental practitioners.

Materials and Methods

Three hundred and four dental and dental hygienist students at Swedish universities were eligible for the survey. Written and oral information was given about the study's aim, methods, anonymity and voluntary participation. The multidimensional questionnaire included 47 closed questions.

Results

The total responding rate was 65.4%; dental students 61.1% and dental hygienist students 92.8%. The total mean of knowledge and attitudes, beneficial for the treating of patient pain, varied between 57.1% and 83.3%. The biggest knowledge gap was identified regarding the items: Children under 2 years of age experience less pain than children over 2 years undergoing similar treatment(34.3%), The dentist is better suited than the parent to judge if a child is in pain (29.4%), and usually the child's pain experience diminishes when the parents are present (24.2%).

Conclusion

Dental and dental hygienist students reported vastly spread knowledge and attitudes regarding pain prophylactic and pain management in children and adolescents, as measured by a multidimensional questionnaire previously used on GDPs. Knowledge on students' understanding of the young patient's pain could help educational efforts to be more student oriented. The questionnaire must be further modified and more extensively tested to meet each participating students' program level.     

Possible predictors of discontinuation of specialized dental treatment among children and adolescents with dental behaviour management problems

Gustafsson A, Broberg AG, Bodin L, Berggren U, Arnrup K. Possible predictors of discontinuation of specialized dental treatment among children and adolescents with dental behaviour management problems. Eur J Oral Sci 2010; 118: 270–277. © 2010 The Authors. Journal compilation © 2010 Eur J Oral Sci This study aimed to identify potential predictors of non‐attendance among children and adolescents with dental behaviour management problems (DBMP). A group of 179 patients, 7.5–19 yr of age, was grouped into 56 ‘non‐attenders’ (discontinued treatment, missed appointments, or ≥ 20% cancellations) and 123 ‘attenders’. In addition to data from an introductory interview and dental recordings, baseline data from psychometric measures of fear and other personal and parental characteristics were included in logistic regression analyses and tree‐based modelling. The non‐attenders had higher scores on impulsivity and sociability and lower socio‐economic status (SES) than the attenders, and they lived more often in single‐parent families. Logistic regression analyses and tree‐based modelling point to SES and parental anxiety as important predictors for non‐attendance within this group of children and adolescents. To predict, and possibly to prevent, non‐attendance among children and adolescents referred for specialized dental care because of DBMP, we must consider their lives and family situations as well as their personal characteristics and oral health status. Further research should focus on whether the observed associations between non‐attendance and factors such as personal characteristics, family and psychosocial factors, and previous dental experiences, also hold for those who remain in regular dental care.     

Dental fear and subjective oral impacts among adults in Finland

We aimed to study the association between subjective oral impacts and dental fear adjusted for age, gender, level of education, and dental attendance, and to evaluate whether this association was modified by the number of remaining teeth. Nationally representative data on Finnish adults, 30+ yr of age (n = 5,987), were gathered through interviews, clinical examination, and questionnaires. Dental fear was measured using the question: ‘How afraid are you of visiting a dentist?’ and subjective oral impacts were measured using the 14‐item Oral Health Impact Profile (OHIP‐14) questionnaire. The outcome variables were the percentage of people reporting one or more OHIP‐14 items fairly often or very often, and the ‘extent’ and ‘severity’. Those with high dental fear reported higher levels of prevalence, ‘extent’, and ‘severity’ of subjective oral impacts than did those with low dental fear or no fear. The association between dental fear and subjective oral impacts was not significantly modified by the number of remaining teeth. The greatest differences between those with high dental fear and low dental fear were found in psychological, social, and handicap dimensions, but not in functional or physical dimensions of the OHIP‐14. Treating dental fear could have positive effects on subjective oral impacts by reducing psychological and social stress and by improving regular dental attendance and oral health.     

Socio-behavioral predictors of changes in dentition status: a prospective analysis of the 1942 Swedish birth cohort

Astrom AN, Ekback G, Ordell S, Unell L. Socio‐behavioral predictors of changes in dentition status: a prospective analysis of the 1942 Swedish birth cohort. Community Dent Oral Epidemiol 2011; 39: 300–310. © 2010 John Wiley & Sons A/S Abstract – Objectives: Using a prospective cohort design, this study assessed loss of natural teeth between ages 50 and 65. Guided by a conceptual framework grouping variables according to the life‐course stage at which they would be expected to operate, this study assessed the impacts of socio‐behavioral and disease‐related factors on tooth loss between ages 50 and 65. Methods: In 1992, all 50‐year‐olds in two counties of Sweden were invited to participate in a longitudinal questionnaire survey. Of the total population of 8888 subjects, 6346 responded (71.4%). Of the 6346 subjects who completed the 1992 questionnaire, 4143 (65%) completed postal follow‐ups at ages 55, 60 and 65. Results: For the total sample, the prevalence of having lost at least some teeth increased from 76% at age 50–85.5% at age 65. A total of 14% women and 13% men changed from having all teeth in 1992 to having tooth loss in 2007. Stepwise logistic regression analyses focused on predictors of tooth loss between 1992 and 2007. The following life‐stage predictors achieved or approached statistical significance with respect to overall tooth loss; country of birth and education (early life and young adult life stage), marital status, dental care avoidance because of high cost, smoking and reporting consistent pain (middle‐age and early‐old‐age life stage). Conclusion: Fewer substantial proportions of the 1942 cohort experienced tooth loss between ages 50 and 65. Tooth loss was highly prevalent from age 50 and increased moderately with increasing age. Oral disease‐related factors and socio‐behavioral characteristics such as refraining from dental care because of financial limitations, acting at earlier and later life‐course stages were major risk factors for having tooth loss. Early primary prevention of smoking and increased equitable access to dental care might improve tooth retention throughout the transition from middle age to early‐older age.     

Exploring factors that influence child use of dental services and toothbrushing in New Zealand

Abstract – Objectives: To explore factors contributing to dental service use and toothbrushing among Mäori, Pacific and New Zealand European or Other (NZEO) children in New Zealand. Methods: Data were obtained from the 2002 National Child Nutrition Survey. Models representing demographic, socio‐economic status (SES), lifestyle, dietary, food security and oral health paradigms were tested using logistic regression. Results: Mäori and Pacific children were more likely to not attend for dental care (OR: 1.99 and 2.05 respectively) than NZEO children when age, sex and time lived in New Zealand were accounted for. The addition of household (OR: 1.93 and 2.05 respectively) or lifestyle (OR: 1.95 and 1.81 respectively) factors resulted in minimal OR changes for Mäori or Pacific child dental attendance, whereas addition of dietary (OR: 1.44 and 1.23 respectively) and food security (OR: 1.43 and 1.32 respectively) items reduced the ORs of Mäori and Pacific child dental attendance so they no longer differed significantly to NZEO children. Addition of dental factors increased the ORs of Mäori and Pacific children not utilizing dental services compared with NZEO children (OR: 2.30 and 2.13 respectively). Mäori and Pacific children were more likely to not brush teeth (OR: 3.86 and 1.49 respectively) than NZEO children when age, sex and time lived in New Zealand were accounted for. Addition of dietary factors resulted in a 36% OR reduction of Mäori children not brushing (OR: 2.57), while addition of household SES (OR: 1.06), lifestyle (OR: 1.14), dietary (OR: 0.71) or food security factors (OR: 1.19) reduced the ORs of Pacific children so they were no longer significantly different to NZEO children. Conclusions: Mäori and Pacific children were more likely to have not received dental care (variance largely explained by dietary and food security factors) and Mäori children were more likely to not brush their teeth (variance largely explained by dietary items) than NZEO children.     

Long‐term patterns of dental attendance and caries experience among British adults: a retrospective analysis

There is inconclusive evidence on the value of regular dental attendance. This study explored the relationship between long‐term patterns of dental attendance and caries experience. We used retrospective data from 3,235 adults, ≥16 yrs of age, who participated in the Adult Dental Health Survey in the UK. Participants were classified into four groups (always, current, former, and never regular‐attenders) based on their responses to three questions on lifetime dental‐attendance patterns. The association between dental‐attendance patterns and caries experience, as measured using the decayed, missing, or filled teeth (DMFT) index, was tested in negative binomial regression models, adjusting for demographic (sex, age, and country of residence) and socio‐economic (educational attainment, household income, and social class) factors. A consistent pattern of association between long‐term dental attendance and caries experience was found in adjusted models. Former and never regular‐attenders had a significantly higher DMFT score and numbers of decayed and missing teeth, but fewer filled teeth, than always regular‐attenders. No differences in DMFT or its components were found between current and always regular‐attenders. The findings of this study show that adults with different lifetime trajectories of dental attendance had different dental statuses.     

Characteristics of Patients Seeking Care from Independent Dental Hygienist Practices

Objectives : This study determined demographic characteristics, satisfaction with care, and likelihood of follow-up dentist visits for patients seen in office-based, independent, dental hygienist practices. Methods : New patients were surveyed after their initial visits to independent hygienist practices to assess their demographic characteristics and satisfaction with care at both the beginning of practice operations and 18 months after the start of these practices. Follow-up surveys were sent to patients 12 and 24 months after their initial visits to the independently practicing dental hygienists to determine if patients had visited a dentist. Results : Most respondents were white, female, had attended some college, and reported high family incomes. Ninety-eight percent of respondents were satisfied with their dental hygiene care. Follow-up questionnaires revealed that over 80 percent of respondents visited the dentist within 12 months of receiving dental hygiene care in independent settings. This level of follow-up care with dentists was found both for respondents who reported having a regular dentist at their initial visits with the hygienists and for those who reported not having a regular dentist. Conclusion : Independent practice by dental hygienists provided access to dental hygiene care and encouraged visits to the dentist.     

Behavioural and physiological effect of dental environment sensory adaptation on children's dental anxiety

Dental anxiety is a serious obstacle in conventional oral healthcare delivery. A sensory adapted dental environment (SDE) might be effective in reducing anxiety and inducing relaxation. This study aimed to assess the efficacy of a Snoezelen SDE in reducing anxiety among children undergoing scaling and polishing by a dental hygienist. The Snoezelen environment consists of a partially dimmed room with lighting effects, vibroacoustic stimuli, and deep pressure. Nineteen children, aged 6-11 yr, participated in a cross-over intervention trial. Behavioral parameters included the mean number, duration, and magnitude of anxious behaviors, as monitored by videotaped recordings. Physiological parameters reflecting arousal were monitored by changes in dermal resistance. Results, by all measures, consistently indicated that both behavioral and psychophysiological measures of relaxation improved significantly in the SDE compared with a conventional dental environment. The findings support recommending the SDE as an effective and practical alternative in oral healthcare delivery to anxious children.     

Life‐course social influences on tooth loss and oral attitudes among older people: evidence from a prospective cohort study

This study examined the relationship of trajectories in social condition with oral attitudes and major tooth loss, using the social mobility and accumulation life‐course models in a cohort. Whether social‐condition inequalities remained stable or changed from 65 yr of age to 70 yr of age was investigated. In 1992, 6,346 inhabitants born in 1942 and residing in two Swedish counties agreed to participate in a prospective survey. Of the participants in 1992, 3,585 (47.6% men) completed questionnaires in 1997, 2002, 2007, and 2012. In line with the social‐mobility model, the prevalence of negative oral attitudes and major tooth loss in participants at 65 and 70 yr of age showed a consistent gradient according to social‐condition trajectory, whereby it was lowest among those who were persistently high and highest among those who were persistently low, with the upwardly and downwardly mobile categories being intermediate. A linear graded association between the number of periods with disadvantaged social condition and oral health supported the accumulation model. Both the social mobility and accumulation life‐course models were supported. Social‐condition differentials in negative oral attitudes and tooth loss seem to remain stable or to narrow weakly after the usual age of retirement.
