Perceived Need for Dental Care Among Dentate Older Individuals in Sri Lanka

The authors assessed the perceived need for dental care among 585 older individuals, of whom 235 received a clinical oral examination. Of the 235 participants, only 171 were dentate. The present analysis is limited to this group. Of these 171 dentate adults, 43 percent perceived a need for dental care. Of this sample section, 53 percent perceived a need for dentures. Age, perceived oral health status, presence of mobile teeth, three impact items of the Oral Health Impact Profile‐14 (OHIP‐14) scale—namely “had a painful aching in the mouth, had difficulty in eating and that the diet had been unsatisfactory due problems with teeth, mouth or dentures”–and the total OHIP‐14 score showed significant associations with perceived need for dental care in bi‐vartate analysis. Poor perceived oral health status emerged as the strongest predictor of perceived need for dental care in logistic regression.     

Perceived oral health status,unmet needs,and barriers to dental care among HIV/AIDS patients in a North Carolina cohort: impacts of race

OBJECTIVE: This prospective observational study examined differences in perceived oral health status, treatment needs, dental care utilization patterns, and barriers to care between HIV-infected non-Hispanic blacks and whites in North Carolina. METHODS: 632 adult HIV-infected medical clinic attendees provided information on their oral health status and dental care history during face-to-face interviews with a trained interviewer. RESULTS: Compared to whites, blacks were significantly more likely to be female, older, less educated, have lower income, and have acquired HIV by heterosexual sex or injecting drug use. Although two-thirds of patients reported good oral health, blacks were significantly more likely to have loose teeth, need extractions, and be episodic dental care utilizers. Primary barriers to dental care were cost (30%), fear (19%), and low motivation (13%). Sixty-five percent of patients had unmet dental needs in the last three years. Race, cost, fear, and immune competence were significantly associated with unmet dental need in a multivariable model. CONCLUSIONS: Disparities exist within this HIV-infected population in oral symptoms, utilization patterns, and perceived unmet dental need. Targeted interventions that address barriers to care are needed to help establish preventive dental care patterns in this region, especially among blacks.     

Oral health-related quality of life in a birth cohort of 32-year olds

Abstract – Objectives: To describe oral health‐related quality of life (OHRQoL) among New Zealand adults and assess the relationship between clinical measures of oral health status and a well‐established OHRQoL measure, controlling for sex, socioeconomic status (SES) and use of dental services. Methods: A birth cohort of 924 dentate adults (participants in the Dunedin Multidisciplinary Health and Development Study) was systematically examined for dental caries, tooth loss, and periodontal attachment loss (CAL) at age 32 years. OHRQoL was measured using the 14‐item Oral Health Impact Profile questionnaire (OHIP‐14). The questionnaire also collected data on each study member’s occupation, self‐rated oral health and reasons for seeing a dental care provider. SES was determined from each individual’s occupation at age 32 years. Results: The mean total OHIP‐14 score was 8.0 (SD 8.1); 23.4% of the cohort reported one or more OHIP problems ‘fairly often’ or ‘very often’. When the prevalence of impacts ‘fairly/very often’ was modeled using logistic regression, having untreated caries, two or more sites with CAL of 4+ mm and 1 or more teeth missing by age 32 years remained significantly associated with OHRQoL, after adjusting for sex and ‘episodic’ dental care. Multivariate analysis using Poisson regression determined that being in the low SES group was also associated with the mean number of impacts (extent) and the rated severity of impacts. Conclusions: OHIP‐14 scores were significantly associated with clinical oral health status indicators, independently of sex and socioeconomic inequalities in oral health. The prevalence of impacts (23.4%) in the cohort was significantly greater than age‐ and sex‐standardized estimates from Australia (18.2%) and the UK (15.9%).     

Oral health‐related quality of life among rural‐dwelling Indigenous Australians

Background: There is limited information on the impact of poor oral health on Indigenous Australian quality of life. This study aimed to determine the prevalence, extent and severity of, and to calculate risk indicators for, poor oral health‐related quality of life among a convenience sample of rural‐dwelling Indigenous Australians. Methods: Participants (n = 468) completed a questionnaire that included socio‐demographic, lifestyle, dental service utilization, dental self‐care and oral health‐related quality of life (OHIP‐14) factors. Results: The prevalence of having experienced one or more of OHIP‐14 items ‘fairly often’ or ‘very often’ was 34.8%. The extent of OHIP‐14 scores was 1.88, while the severity was 15.0. Risk indicators for having experienced one or more of OHIP‐14 items ‘fairly often’ or ‘very often’ included problem‐based dental attendance, avoiding dental care because of cost, difficulty paying a $100 dental bill and non‐ownership of a toothbrush. An additional risk indicator for OHIP‐14 extent was healthcare card ownership, while additional indicators for OHIP‐14 severity were healthcare card ownership and having had 5+ teeth extracted. Conclusions: Risk indicators for poor oral health‐related quality of life among this marginalized population included socio‐economic factors, dentate status factors, dental service utilization patterns, financial factors and dental self‐care factors.     

Oral health among white, black, and Mexican-American elders: an examination of edentulism and dental caries

Objectives: To examine racial/ethnic disparities in oral health among older Americans. Methods: Differences in frequency of edentulism and number of decayed, missing, and filled teeth were assessed in 2,679 non‐Hispanic white, 742 non‐Hispanic black, and 934 Mexican‐American individuals aged 60 and older from the National Health and Nutrition Examination Survey (1999‐2004). Results: Controlling for potential confounding variables, blacks and Mexican‐Americans had significantly higher numbers of decayed teeth but fewer numbers of filled teeth than whites. Although blacks had a lower likelihood of being edentulous than whites, dentate blacks had a higher number of missing teeth. Compared with whites, Mexican‐Americans were less likely to be edentulous, and dentate Mexican‐Americans had fewer missing teeth. Our study also showed that blacks and Mexican‐Americans had less frequent dental checkups than whites. Conclusions: Oral health disparities are persistent across racial/ethnic groups for older Americans despite the fact that the differences between groups typically diminish when socioeconomic, health‐related, and behavioral factors are considered in the models. Our study suggests that reducing racial/ethnic oral health disparities requires multiple clinical approaches.     

Root Caries Prevalence in Black and White North Carolina Adults over Age 65

The baseline root caries prevalence of 809 dentate black and white home-dwelling North Carolinians over age 65 was determined along with the collection of a large number of demographic and behavioral, clinical, and microbiological variables in the longitudinal Piedmont over-age-65 Dental Study. In comparison to other studies of older adults, the prevalence of decayed-filled root surfaces (DFRS) was low, fewer than 2.0 DFRS in whites, and significantly fewer than that in blacks (1.3 DFRS). Although tooth loss was a substantial problem, nearly half of the white population and almost two-thirds of the black participants exhibited no evidence of root caries history. Even though DFRS prevalence was much lower in blacks, their treatment need for decayed root surfaces (DRS) was significantly higher than for white participants. Correlates with DRS within both race groups appeared to be those that reflect lack of access to dental services or neglect of oral health--decayed coronal surfaces, higher rates of tooth extraction, high CPITN scores and worst loss of attachment greater than or equal to 7 mm, and more than a year since the last dental visit. Some variables were associated significantly with one racial group, but not the other, while others, particularly root surfaces at risk and age, were not associated significantly with DRS. We concluded that although there was considerable neglect of root caries, particularly among blacks, it was not a serious problem among older North Carolinians.     

Etiologic models for incident periodontal attachment loss in older adults

Etiologic factors for incident periodontal attachment loss (ALOSS) have not been conclusively identified. The purpose of this study was to develop etiologic models for ALOSS in older adults. Data on 697 older blacks and whites were obtained from 5 sequential examinations over 7 years in the Piedmont 65+ dental study, a complex random sample of older adults in North Carolina. Multivariable Poisson regression models were fit for average number of ALOSS events per person or site month at risk. In models for whites, molar sites, sites with adjacent caries, sites in persons who had: Porphyromonas gingivalis (P.g.) at least 2% of total microbial count (TMC), never had a dental checkup, more depression symptoms, fewer than 12 years of education, higher BANA score, or smoked, had significantly higher rates of ALOSS. In a separate model for blacks, interproximal and molar sites, sites in blacks who had: P.g. at least 2% of TMC, higher BANA score, never had a dental checkup, lower socioeconomic status (SES), or smoked, had significantly higher rates of ALOSS. These results confirm a multifactorial etiology for ALOSS in older adults and indicate that interventions aimed at infection, smoking, and preventive dental care utilization, may be most useful.     

Three-year Root Caries Incidence and Risk Modeling in Older Adults in North Carolina

Objectives : The purposes of this study were to describe the incidence of root caries and to identify its risk factors in a representative sample of older adults. Methods : Root caries incidence was estimated and multivariate risk assessment models were developed to identify predictors for root caries in a three-year follow-up study of 234 black and 218 white noninstitutionalized adults aged 65 and older residing in North Carolina. Results : During the observation period, 29 percent of blacks developed root caries, compared to 39 percent of whites (P<.05). The mean net DFS increment per person was 0.55±0.13 root surfaces for blacks vs 0.80±0.21 for whites (P>.32). Multivariate logistic regression analysis indicated that blacks wearing a partial denture, having some root fragments, having an average gingival recession ≥2 mm, and being free of P. intermedia were at greater risk for developing new root caries. The model for whites showed that retired people with their most severe gingival recession ≥4 mm, an average probing pocket depth ≥2 mm, and taking antihistamines were more likely to develop new lesions. Conclusions : These findings suggest that older blacks had less risk of root caries than whites, and in both groups indicators of poor periodontal status increased the risk of root caries.     

Social impact of oral conditions among older adults

Oral symptoms and their effects on well-being provide an indication of the social impact of oral disease and can be used to document the burden of illness within populations. This report presents findings about the social impact of oral disease among a random sample of 1217 non-institutionalized persons aged 60 years and over living in Adelaide and Mt Gambier. They completed a questionnaire containing 49 questions about the effect of oral conditions on dysfunction, discomfort and disability. Over 5 per cent of dentate persons and over 10 per cent of edentulous persons reported impacts such as difficulty in chewing, discomfort during eating and avoidance of foods 'fairly often' or 'very often' during the previous 12 months. Impacts on social roles and interpersonal relationships were reported by up to 5 per cent of persons. Edentulous persons reported social impact more frequently, particularly in areas related to chewing and eating. Older age was associated with significantly greater amounts of impact among dentate persons, while edentulous males reported significantly more impact than edentulous females. There were larger variations among dentate persons according to their dental utilization patterns, with the highest levels of impact reported by individuals who usually attended for dental problems and who had attended the previous year. The high frequency of social impact reported in this study no doubt reflects extensive levels of disease experience, including high rates of missing teeth and edentulism, among older adults.     

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.     

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.     

Effect of examining half the teeth in a partial periodontal recording of older adults

Limited evidence to date has suggested that half-mouth examinations can be used in epidemiological surveys for accurate estimation of the prevalence of periodontal conditions. This study investigated the accuracy and efficiency of half-mouth periodontal examinations of mesial and buccal sites by comparing whole-mouth findings from those sites with findings that would have been obtained by examining only two randomly selected quadrants of teeth in three older dentate adult populations: 263 whites in Iowa, 309 whites in North Carolina, and 384 blacks in North Carolina. Mean half-mouth scores for gingival recession, pocket depth, attachment loss, and Extent and Severity Index were almost identical to those of mean whole-mouth scores, with correlations between means exceeding 0.93. However, the proportions of the population having selected levels of moderate or severe periodontal disease in mesial and buccal sites were underestimated by as much as 13%. This study showed that half-mouth examinations can be accurate and efficient in estimating mean periodontal measures, but may underestimate the prevalence of periodontal conditions.     

Impact of oral disease on quality of life in the US and Australian populations

Abstract – The US National Health and Nutrition Examination Survey (NHANES 2003–2004) evaluated oral health quality of life for the first time using a previously untested subset of seven Oral Health Impact Profile (OHIP) questions, i.e. the NHANES‐OHIP. Objectives: (i) To describe the impact of dental conditions on quality of life in the US adult population; (ii) to evaluate construct validity and adequacy of the NHANES‐OHIP in NHANES 2003–2004 and a comparable Australian survey. Methods: In the cross‐sectional NHANES 2003–2004 survey of a nationally representative sample of US adults (n = 4907), prevalence was quantified as the proportion of adults who reported experiencing one or more impacts fairly often or very often within the past year. Construct validity was tested by comparing prevalence estimates across categories of sociodemographic, dental health and utilization characteristics known to vary in oral health. In 2002, Australian cross‐sectional survey of a nationally representative sample of adults (n = 2644), adequacy of the NHANES‐OHIP questions were tested with reference to a slightly modified version of the OHIP‐14 questions. Results: NHANES‐OHIP prevalence estimates were markedly similar in the United States (15.3%) and Australia (15.7%). In the US construct, validity was evidenced by higher NHANES‐OHIP scores among groups with greater levels of tooth loss, perceived treatment need and problem‐oriented visiting and with lack of private dental insurance and low income. In Australia, prevalence for the NHANES‐OHIP closely resembled prevalence estimates of the modified OHIP‐14. Both varied to a similar degree across levels of tooth loss, perceived treatment need, problem‐oriented visiting, and private dental insurance and income, demonstrating adequacy of the NHANES‐OHIP as a brief independent instrument. Conclusions: There was acceptable construct validity and adequacy of the NHANES‐OHIP questionnaire. In the United States, the impact of oral disease disproportionately affected disadvantaged groups, a finding that supports application of the US Healthy People 2010 major goals of improved quality of life and reduced health disparities.     

The prevalence and experience of oral diseases in Adelaide nursing home residents

BACKGROUND: The twenty-first century will see the evolution of a population of dentate older Australians with dental needs very different from those of older adults in past years. This study provided comprehensive information concerning oral disease prevalence in older South Australian nursing home residents. METHODS: This paper presents cross-sectional baseline results. RESULTS: Most of the 224 residents, from seven randomly selected nursing homes, were functionally dependent, medically compromised, cognitively impaired and behaviourally difficult older adults who presented many complex challenges to carers and to dental professionals. Two-thirds (66 per cent) were edentulous with many dental problems and treatment needs. Dentate residents had a mean of 11.9 teeth present, higher than previously reported. The prevalence and experience of coronal and root caries and plaque accumulation was very high in dentate residents; especially males, those admitted more than three years previously, those who ate fewer food types and those who were severely cognitively impaired. These residents had more retained roots, decayed teeth and missing teeth, and fewer filled teeth when compared with data for community-dwelling older adults. CONCLUSIONS: This study highlighted the poor oral health status of these nursing home residents and the great impact of dementia on their high levels of oral diseases.     

Racial Differences in Stage at Diagnosis of Screenable Oral Cancers in North Carolina

Objective : This study examined differences between blacks and whites in stage at diagnosis of screenable oral cancers. Methods : Data for 1,137 North Carolina residents with first primary tumors of the oral cavity (excluding the lip and salivary glands) or oropharynx diagnosed from 1990–92 were obtained from the North Carolina Central Cancer Registry. The outcome variable was stage at diagnosis dichotomized as localized and advanced. The explanatory variables were race, sex, age, year diagnosed, tumor site, and county-level socioeconomic and health care resource factors. Bivariate, stratified, and multiple regression analyses were conducted. Results : In the regression analysis, the odds of advanced stage was 2.1 (95% Cl=1.5, 2.9) times greater for blacks than whites. Other multivariable effects were sex [males compared to females: OR=1.5 (95% Cl=1.2, 2.0)] and tumor site [oropharynx compared to palate: OR=4.2 (95% Cl=2.5, 7.0)]. Conclusion : Among black and white residents of North Carolina diagnosed with cancer of the oral cavity or oropharynx, blacks had a greater odds of diagnosis at advanced stage.     

Determinants of dental referral practices among WIC nutritionists in North Carolina

OBJECTIVES: To examine the effects of knowledge and confidence on dental referral practices among WIC nutritionists in North Carolina. METHODS: A questionnaire consisting of 118 Likert scale-type questions was administered to 92% of all WIC nutritionists in North Carolina (n = 324). The relationship of knowledge and confidence with frequent dental referrals was tested using logistic regression. RESULTS: Regression results found that confidence in performing oral health risk assessments (OR = 2.12; 95% CI = 1.13, 3.96), confidence in making dental referrals (OR = 3.02; 95% CI = 1.45-6.29), and confidence in expected outcomes that parents would seek dental care when advised to do so (OR = 3.11; 95% CI = 1.62, 5.97) were associated with more frequent dental referrals. CONCLUSIONS: The more confident WIC nutritionists feel about oral health, the more likely they are to make dental referrals. Screening and referral by WIC workers may benefit children by improving access to dental care, as the WIC clinic is frequently the first point of contact with a health professional.     

Oral health-related quality of life in tumour patients treated with patient-specific dental implants

Dental rehabilitation after surgically acquired bone deficiency related to tumour treatment remains a challenge. The insertion of patient-specific implants geared to the contour of the remaining bone is a feasible method of supporting fixed or removable dentures. As oral health-related quality of life (OHRQoL) is of great interest in these cases, 12 individuals treated with patient-specific implants for severe bone deficiency were surveyed and their Oral Health Impact Profile (OHIP) scores after dental rehabilitation were evaluated. The OHIP-G53 questionnaire was used to measure overall treatment outcomes. The distribution of OHIP sum-scores for participants treated with patient-specific implants was almost homogeneous when compared to those cited in the literature for patients treated with conventional dental implants. OHIP items related to functional impairment and physical pain showed the highest scores (occurring occasionally), and financial loss related to treatment was frequently stated. Moreover, higher scores were detected in almost all OHIP dimensions for participants with patient-specific implant-supported removable dentures. Conversely, those treated with patient-specific dental implants and fixed dentures showed lower psychosocial impact scores and equal or superior OHRQoL. Hence, patient-specific dental implants, especially combined with fixed dentures, can lead to a positive OHRQoL in patients with severe bone deficiencies related to tumour therapy.     

Developing short-form measures of oral health-related quality of life

OBJECTIVES: Using the item-impact method, we developed an alternative short-form Oral Health Impact Profile (OHIP) that has good psychometric properties and minimal floor effects. METHODS: OHIP data were collected from a sample of older Canadians at two points in time. Data from the first administration were used to develop a 14-item short-form measure; data from the second compare the latter's psychometric properties with those of the original short form developed by Slade (1997), who used a controlled regression procedure. RESULTS: The short form based on the item-impact method had only two items in common with the short form derived from the regression approach and contained more high-prevalence items. The regression short form was subject to marked floor effects, while the impact short form had floor effects comparable to those of the full 49-item OHIP. The former discriminated between dentate and edentulous subjects, while the latter did not. Both discriminated between dentate subjects who did and did not wear dentures, those with and without dry mouth, and those with and without chewing problems. Both were also significantly associated with self-ratings of oral health, satisfaction with oral health, and self-perceived need for dental treatment. The strength of the associations was somewhat stronger with the regression short form, indicating that it performed better as a discriminatory instrument. However, because of its floor effects, it was markedly less sensitive to change than the impact short form. There was an indication that item-impact methods of shortening oral health-related quality of life measures produced more stable results across samples than the statistical approach. CONCLUSIONS: Because the content validity of short-form measures is always compromised, different short forms are required for different purposes and different patient populations. The regression short form developed by Slade (1997) is likely to be better when the aim is to discriminate, while the impact short form developed here may be preferable when the aim is to describe the oral health-related quality of life of populations or to detect change.     

Oral health and its impact on the life quality of homeless people in Hong Kong

OBJECTIVES: To report on the oral health status and its impact on the life quality of homeless people in Hong Kong. DESIGN: A cross sectional epidemiological survey involving clinical oral examinations and face-to-face interviews with 147 homeless participants. Clinical examinations were carried out following WHO criteria. The impact of oral health on quality of life was assessed with the short form of Oral Health Impact Profile, OHIP-14. RESULTS: Over 90% had caries experience and most related to untreated decay. The mean DMFT score for dentate subjects was 8.1 (DT = 3.4, MT = 4.0, FT = 0.7). Periodontal disease was highly prevalent, 96% having periodontal pockets. The burden of oral health on their daily lives was common, 88% reporting an oral health impact within the past year. A multiple regression analysis indicated that the OHIP-14 score had significant associations with self-rated oral health, dental pain, employment status and length of time being homeless (p < 0.05). Those who assessed rated oral health as 'poor/very poor', reported dental pain in the past year, were unemployed, and homeless for more than one year had poorer oral health related quality of life (significantly higher OHIP scores) than their counterparts. CONCLUSION: Among the homeless population studied, oral health status was poor and its impact on their life quality was substantial. The oral health impact was associated with socio-demographics and perceived dental problems.     

Oral self-care and periodontal health indicators among adults with diabetes in Finland

We assessed the effects of oral self-care on periodontal health indicators among adults with diabetes. The sample consisted of 120 dentate individuals, all of whom were regular patients at the Salo Regional Hospital Diabetes Clinic in southwest Finland. Clinical periodontal examination included identification of visible plaque, the presence of calculus, and use of the Community Periodontal Index of Treatment Needs (CPITN). A questionnaire focused on self-treatment, self-prevention, and self-diagnosis of oral diseases, utilization of dental services, and patients' knowledge and attitudes towards oral health. The New Century model of oral health promotion was used as a theoretical framework for analysis of determinants of oral self-care. Although individuals aged 40 years or older were more frequent interdental cleaners, significantly better oral health indicators were found among younger patients. Women reported brushing their teeth more frequently, and differences in plaque and calculus indices were significantly lower than those of men. Self-reported good oral condition was strongly associated with frequent dental visits and less plaque and calculus. No missing teeth and age less than 40 years were predictors of lower plaque, calculus, and CPITN scores. A significant association was found only between frequent dental visits and reduced amount of calculus. Self-reported frequency of oral health habits among adults with diabetes seemed to have little effect on periodontal health indicators. Adults with diabetes should benefit from comprehensive oral selfcare, and more attention is needed for improving the quality and outcome of these habits.
