Can questionnaires replace clinical surveys to assess dental treatment needs of adults?

Evaluating the harmonization potential of oral health-related questionnaires in national longitudinal birth and child cohort surveys

BACKGROUND/OBJECTIVES

Effective use of longitudinal study data is challenging because of divergences in the construct definitions and measurement approaches over time, between studies and across disciplines. One approach to overcome these challenges is data harmonization. Data harmonization is a practice used to improve variable comparability and reduce heterogeneity across studies. This study describes the process used to evaluate the harmonization potential of oral health-related variables across each survey wave.

METHODS

National child cohort surveys with similar themes/objectives conducted in the last two decades were selected. The Maelstrom Research Guidelines were followed for harmonization potential evaluation.

RESULTS

Seven nationally representative child cohort surveys were included and questionnaires examined from 50 survey waves. Questionnaires were classified into three domains and fifteen constructs and summarized by age groups. A DataSchema (a list of core variables representing the suitable version of the oral health outcomes and risk factors) was compiled comprising 42 variables. For each study wave, the potential (or not) to generate each DataSchema variable was evaluated. Of the 2100 harmonization status assessments, 543 (26%) were complete. Approximately 50% of the DataSchema variables can be generated across at least four cohort surveys while only 10% (n = 4) variables can be generated across all surveys. For each survey, the DataSchema variables that can be generated ranged between 26% and 76%.

CONCLUSION

Data harmonization can improve the comparability of variables both within and across surveys. For future cohort surveys, the authors advocate more consistency and standardization in survey questionnaires within and between surveys.

Simplifying Oral health evaluation: a novel approach through single-item surveys

BACKGROUND

This study adopts a novel approach of using single-item surveys to simplify the assessment of oral health status and behaviors among Japanese private sector employees. We aimed to establish the validity of self-reported oral health in relation to clinical dental examinations, and to elucidate the relationship between oral diseases, health behaviors, and self-assessments. A secondary aim was to explore the association of self-rated oral health with oral health behaviors.

MATERIALS AND METHODS

Self-administered questionnaires and dental examinations were obtained from 2262 Japanese private sector employees. Workers self-rated their overall oral health status according to five choices: "very good," "good," "fair," "poor," or "bad." Self-reports were then compared with the results of clinical dental examinations, which included measuring the oral hygiene index (DI-S), the number of decayed teeth, periodontal status (Community Periodontal Index) and number of missing teeth. Convergent validity was also tested by examining the correlations of self-reported oral health status with oral health behaviors.

RESULTS

Overall, 30.8% of workers reported their oral health as "poor" or "bad." "Poor" or "bad" oral health status was significantly correlated with missing teeth, periodontitis, and decayed teeth. However, lower correlations were found for gingivitis and the oral hygiene index. Most self-reported oral health behaviors were correlated with self-rated oral health; exceptions were "tooth brushing instructions received in a dental clinic," "having a primary-care dentist," and "habitual snacking between meals."

CONCLUSIONS

Self-rated oral health provides reasonably valid data, and correlated well with clinically assessed oral health status, including dental caries, periodontal status, and tooth loss. Convergent validity was also found for oral health behaviors.

Integration, effectiveness and costs of different models of primary health care provision for people who are homeless: an evaluation study

Background

There is a high prevalence of health problems among single people who are homeless. Specialist primary health care services for this population have been developed in several locations across England; however, there have been very few evaluations of these services.

Objectives

This study evaluated the work of different models of primary health care provision in England to determine their effectiveness in engaging people who are homeless in health care and in providing continuity of care for long-term conditions. It concerned single people (not families or couples with dependent children) staying in hostels, other temporary accommodation or on the streets. The influence on outcomes of contextual factors and mechanisms (service delivery factors), including integration with other services, were examined. Data from medical records were collated on participants' use of health care and social care services over 12 months, and costs were calculated.

Design and setting

The evaluation involved four existing Health Service Models: (1) health centres primarily for people who are homeless (Dedicated Centres), (2) Mobile Teams providing health care in hostels and day centres, (3) Specialist GPs providing some services exclusively for patients who are homeless and (4) Usual Care GPs providing no special services for people who are homeless (as a comparison). Two Case Study Sites were recruited for each of the specialist models, and four for the Usual Care GP model.

Participants

People who had been homeless during the previous 12 months were recruited as 'case study participants'; they were interviewed at baseline and at 4 and 8 months, and information was collected about their circumstances and their health and service use in the preceding 4 months. Overall, 363 participants were recruited; medical records were obtained for 349 participants. Interviews were conducted with 65 Case Study Site staff and sessional workers, and 81 service providers and stakeholders.

Results

The primary outcome was the extent of health screening for body mass index, mental health, alcohol use, tuberculosis, smoking and hepatitis A among participants, and evidence of an intervention if a problem was identified. There were no overall differences in screening between the models apart from Mobile Teams, which scored considerably lower. Dedicated Centres and Specialist GPs were more successful in providing continuity of care for participants with depression and alcohol and drug problems. Service use and costs were significantly higher for Dedicated Centre participants and lower for Usual Care GP participants. Participants and staff welcomed flexible and tailored approaches to care, and related services being available in the same building. Across all models, dental needs were unaddressed and staff reported poor availability of mental health services.

Limitations

There were difficulties recruiting mainstream general practices for the Usual Care GP model. Medical records could not be accessed for 14 participants of this model.

Conclusions

Participant characteristics, contextual factors and mechanisms were influential in determining outcomes. Overall, outcomes for Dedicated Centres and for one of the Specialist GP sites were relatively favourable. They had dedicated staff for patients who were homeless, 'drop-in' services, on-site mental health and substance misuse services, and worked closely with hospitals and homelessness sector services.

A Cross-Sectional Study of Perceived Dental Treatment Needs and Oral Health Status in Community-Dwelling Older Australian Men: The Concord Health and Ageing in Men Project

Background

Assessing perceived needs for dental treatment is important in understanding and predicting people's health behaviours. The purpose of this study is to examine older men's perceptions regarding dental treatment needs, and to investigate the disparity between perceived needs and the actual oral health of a population of community-dwelling older Australians.

Methods

Using cross-sectional data from the 4th wave of the Concord Health and Ageing in Men Project, logistic regression analysis of perceived needs for dental treatment was conducted for 596 men aged 78 and over, with functional tooth units (FTUs), number of decayed tooth surfaces, and periodontitis as independent variables.

Results

Thirty-six percent (n = 216) of the participants believed they required some form of dental treatment. The remaining participants did not perceive a need for treatment, yet 65.3% objectively required prosthodontic or restorative care. The regression model showed men with lower FTUs were significantly more likely to report a perceived need for dental treatment than those with 12 FTUs [0–6 FTUs: adjusted odds ratio (OR) 2.58, 95% CI 1.28–5.20; 7–11 FTUs: adjusted OR 2.43, 95% CI 1.16–5.10]. However, neither the number of decayed tooth surfaces nor the existence of periodontitis was associated with perceived dental treatment needs.

Conclusions

Most older men viewed their oral health positively, and the majority of those with objectively assessed needs, did not perceive themselves as requiring dental treatment. Loss of FTUs appears to alert participants to seek treatment, but not the presence of dental caries or periodontitis.

Validity of self-reported periodontal measures, demographic characteristics, and systemic medical conditions

BACKGROUND

The objective of the present study was to assess self-reported periodontal screening questions, demographic characteristics, systemic medical conditions, and tobacco use for predicting periodontal disease among individuals seeking dental therapy in a university dental clinic.

METHODS

In this retrospective study, a total of 4,890 randomly selected dental charts were evaluated from among patients who had attended the University of Minnesota School of Dentistry clinics for treatment. Radiographic bone loss measurements were used to assess the severity of periodontal disease. Demographic characteristics as well as medical history of the patients were also recorded. Five self-reported periodontal screening questions were included, with answers limited to Yes/No. Generalized logit models were used to assess the association between bone loss and the predictors.

RESULTS

The sample's mean age was 54.1 years and included 52.6% males and 14.9% smokers, with a mean of 3.5 missing teeth. Self-reported tooth mobility, history of "gum treatment," and the importance of retaining teeth as well as age, tobacco use, and cancer were statistically significant predictors (P < 0.05) of a radiographic diagnosis of moderate and severe periodontal disease. With respect to severe periodontal disease, significant associations (P < 0.05) were also found with "bleeding while brushing," gender, diabetes, anxiety, and arthritis.

CONCLUSIONS

Self-reported periodontal screening questions as well as demographic characteristics, smoking, and systemic medical conditions were significant predictors of periodontal disease, and they could be used as valid, economic, and practical measures.

Inequality in unmet dental care needs among South Korean adults

Background

The current public health research agenda was to identify the means to reduce oral health inequalities internationally. The objectives of this study were to provide evidence of inequality in unmet dental needs and to find influencing factors attributable to those among South Korean adults.

Methods

Pooled cross-sectional data from the fourth Korean National Health and Nutrition Examination Survey (2007–2009) on 17,141 Korean adults were used. Demographic factors (sex, age, and marital status), socioeconomic factors (education level, employment status, and income level), need factors (normative dental needs and self-perceived oral health status), and oral health-related factors (the number of decayed teeth, the presence of periodontitis, and the number of missing teeth) were included. Multiple logistic regression analysis was performed.

Results

Of South Korean adults, 43.9% had perceived unmet dental needs, with the most common reason being financial difficulties. The disparities in unmet dental care needs were strongly associated with income level, normative treatment needs, and self-perceived oral health status. The low-income group, people with normative dental treatment needs, and those with perceived poor oral health status were more likely to have unmet dental needs. There was considerable inequality in unmet dental care needs due to economic reasons according to such socioeconomic factors as income and education level.

Conclusions

Public health policies with the expansion of dental insurance coverage are needed to reduce inequalities in unmet dental care needs and improve the accessibility of dental care services to vulnerable groups who are experiencing unmet dental care needs due to socioeconomic factors despite having normative and self-perceived needs for dental treatment.

The Self-Reported Oral Health Status and Dental Attendance of Smokers and Non-Smokers in England

Smoking has been identified as the second greatest risk factor for global death and disability and has impacts on the oral cavity from aesthetic changes to fatal diseases such as oral cancer. The paper presents a secondary analysis of the National Adult Dental Health Survey (2009). The analysis used descriptive statistics, bivariate analyses and logistic regression models to report the self-reported oral health status and dental attendance of smokers and non-smokers in England. Of the 9,657 participants, 21% reported they were currently smoking. When compared with smokers; non-smokers were more likely to report ‘good oral health’ (75% versus 57% respectively, p<0.05). Smokers were twice as likely to attend the dentist symptomatically (OR = 2.27, CI = 2.02–2.55) compared with non-smoker regardless the deprivation status. Smokers were more likely to attend symptomatically in the most deprived quintiles (OR = 1.99, CI = 1.57–2.52) and perceive they had poorer oral health (OR = 1.77, CI = 1.42–2.20). The present research is consistent with earlier sub-national research and should be considered when planning early diagnosis and management strategies for smoking-related conditions, considering the potential impact dental teams might have on smoking rates.

Validade e utilidade da autopercepção de necessidade de tratamento odontológico por adultos e idosos

O objetivo deste trabalho foi determinar a validade das medidas de autopercepção como indicador de necessidades de tratamentos odontológicos em adultos e idosos. A amostra foi composta por indivíduos que participaram da Pesquisa Nacional de Saúde Bucal e da Pesquisa sobre as Condições de Saúde Bucal da População Mineira. A autopercepção da necessidade de tratamento dentário e de prótese total foi comparada com a necessidade determinada a partir do exame odontológico, considerado padrão-ouro. A qualidade das medidas foi avaliada por meio da sensibilidade, da especificidade e de valores preditivos. A sensibilidade variou de 51% a 90%, enquanto a especificidade ficou entre 56% e 90%. Os valores preditivos positivos foram de 11% a 95%, e os negativos, de 23% a 99%. A autopercepção de necessidade de tratamento dentário em adultos e de necessidade de próteses totais em idosos apresentou valores aceitáveis de validade. Por outro lado, a autopercepção da necessidade de tratamento por idosos e da necessidade de próteses totais por adultos não foi considerada útil devido a seu baixo desempenho.

Do self-assessed oral health and treatment need associate with clinical findings? Results from the Finnish Nationwide Health 2000 Survey

OBJECTIVE

To associate self-assessed oral health and treatment need with clinically determined findings.

MATERIALS AND METHODS

As part of the Finnish nationwide comprehensive Health 2000 Survey, the present cross-sectional study included dentate participants aged 30-64 years who self-assessed their oral health and treatment need in an interview and who underwent a clinical oral health examination (n = 4385). Self-assessed oral health and treatment need were used as subjective indicators. Clinically determined dental and periodontal status described objective dental and periodontal health and treatment need. The evaluation of relationships between subjective and objective findings was based on two-by-two tables and multivariate analyses.

RESULTS

The better the self-assessed oral health, the better the objective dental and periodontal health. Those reporting need for treatment more often had the objective need in terms of dental or periodontal treatment, also when controlling for background factors. Of the subjective indicators, good self-assessed oral health best reflected the absence of clinically determined dental or periodontal treatment need. Those who reported a need for treatment were mainly adults with an objective dental and periodontal treatment need.

CONCLUSIONS

Self-assessed good oral health is a fairly good estimate for the absence of clinically determined dental and periodontal treatment need. As implication for practice, self-assessed data could be used for screening purposes for oral health service planning and for priority allocation in large adult populations.

Determinants of preventive oral health behaviour among senior dental students in Nigeria

BACKGROUND

To study the association between oral health behaviour of senior dental students in Nigeria and their gender, age, knowledge of preventive care, and attitudes towards preventive dentistry.

METHODS

Questionnaires were administered to 179 senior dental students in the six dental schools in Nigeria. The questionnaire obtained information on age, gender, oral self-care, knowledge of preventive dental care and attitudes towards preventive dentistry. Attending a dental clinic for check-up by a dentist or a classmate within the last year was defined as preventive care use. Students who performed oral self-care and attended dental clinic for check-ups were noted to have complied with recommended oral self-care. Chi-square test and binary logistic regression models were used for statistical analyses.

RESULTS

More male respondents agreed that the use of fluoride toothpaste was more important than the tooth brushing technique for caries prevention (P < 0.001). While the use of dental floss was very low (7.3%), more females were more likely to report using dental floss (p=0.03). Older students were also more likely to comply with recommended oral self-care (p<0.001). In binary regression models, respondents who were younger (p=0.04) and those with higher knowledge of preventive dental care (p=0.008) were more likely to consume sugary snacks less than once a day.

CONCLUSION

Gender differences in the awareness of the superiority of using fluoridated toothpaste over brushing in caries prevention; and in the use of dental floss were observed. While older students were more likely to comply with recommended oral self-care measures, younger students with good knowledge of preventive dental care were more likely to consume sugary snacks less than once a day.

Dental prosthetic treatment needs of inpatients with schizophrenia in Taiwan: a cross-sectional study

BACKGROUND

The need to obtain information on the dental prosthetic treatment needs (DPTNs) of inpatients with schizophrenia is unrecognized. This study aims to assess the DPTNs of this population and investigate the association between these needs and related factors.

METHODS

The results of an oral health survey involving 1,103 schizophrenic adult inpatients in a long-term care institution in Taiwan were used. Chi-square tests and multiple logistic analyses were used to measure the independent effects of the characteristics of each subject on their DPTNs.

RESULTS

Of the subjects, 805 (73.0%) were men and 298 (27.0%) were women. The mean age was 50.8 years. A total of 414 (37.5%) required fixed prosthesis, whereas 700 (63.5%) needed removable prosthesis. Multivariate analyses show that fixed prosthesis is associated with age only after adjusting for other potential independent variables. Older subjects who had a lower educational attainment or a longer length of stay required removable prosthesis.

CONCLUSIONS

The findings of this study show that the DPTNs of schizophrenic inpatients are not being met. Therefore, a special approach to the dental prosthetic treatment of these patients should be developed.

Self-Reported Oral Health Status of Adults Resident in Medway, Kent in 2009

Aim

In order to assess the oral health status, oral behaviours and use of oral healthcare services of the adult population of Medway (Kent) in 2009, NHS Medway commissioned an assessment. Its aims were to understand oral health and impacts, behaviours and the use of dental services in order to inform future development of dental services.

Methods

A self-reported postal questionnaire survey using relevant questions from the 1998 national Adult Dental Health Survey (ADHS) was performed. A stratified sample was drawn from all those aged 16 years and over, living in Medway and registered with a general medical practice. Stratification was into the three areas within Medway (Chatham, Gillingham and Rainham, and Rochester and Strood). Where appropriate, respondents answered the questions using a five-point Likert scale. The resulting data were analysed by area of domicile, age, gender, and deprivation.

Results

Eight thousand questionnaires were sent out, of which 3101 (39%) were returned. Because of this low response and the need to weight responses to represent the distribution of the Medway population, this investigation must be considered as a service evaluation rather than a research project. Of respondents, 4% were edentate, 16% had 1–20 teeth, and 80% had 21 or more teeth. Fifty-one per cent of respondents reported at least one oral health impact; most commonly this was physical pain and psychological discomfort; least commonly, social disability and handicap. Sixteen per cent reported that their last dental visit was over 24 months ago and 31% reported that they attended only when in trouble or never (most commonly, because of anxiety and cost). There were marked variations in oral health status and use of dental services between those living in the most and least deprived areas.

Conclusions

• Medway adults were more likely than the 2009 national ADHS respondents to be dentate but less likely to have 21 or more teeth. • Oral health impacts have been substantial, especially the experience of physical pain. • Proportionately more people than the 2009 national ADHS respondents reported attending a dentist in the previous 24 months. The most common reasons for non-attendance were anxiety and cost. • These findings have implications for the future development of the Medway oral health strategy and for all those working in primary care dentistry.

Validade do padrão de higiene bucal de crianças aos cinco anos de idade relatado pelas mães

OBJETIVO: Determinar a validade de perguntas freqüentemente utilizadas em estudos epidemiológicos sobre higiene bucal de crianças e compará-la segundo renda familiar e escolaridade da mãe. MÉTODOS: Foram analisadas 1.122 crianças participantes do subestudo de saúde bucal de 2009 da Coorte de Nascimentos de Pelotas, RS, 2004. As crianças foram examinadas e suas mães entrevistadas no domicílio. O padrão-ouro da condição de higiene bucal foi avaliado por meio do Índice de Higiene Oral Simplificado e a partir do seu escore total o desfecho foi dicotomizado em: placa dental ausente (escore total = 0) e presente (escore total ≥ 1). As perguntas testadas sobre o padrão de higiene bucal das crianças foram formuladas às mães e incluíram: freqüência diária de escovação, escovação antes de dormir e a combinação dessas duas (higiene bucal), com suas opções de resposta dicotomizadas em regular e irregular. A validade foi determinada por meio do cálculo dos valores percentuais e respectivos intervalos de 95% de confiança de sensibilidade, especificidade, valor preditivo positivo e valor preditivo negativo. RESULTADOS: A prevalência de placa dental foi 37,0%. Os valores de sensibilidade, especificidade, valor preditivo positivo e valor preditivo negativo foram, respectivamente: 29,6%, 82,5%, 49,8% e 66,6%, para freqüência de escovação diária irregular; 41,8%, 64,6%, 40,9% e 65,5%, para escovação antes de dormir irregular; 48,8%, 60,8%, 42,2% e 67,0%, para higiene bucal irregular. A validade do padrão de higiene bucal variou conforme o nível de renda familiar e a escolaridade da mãe, e a sensibilidade e o valor preditivo positivo foram maiores entre os indivíduos com menor renda familiar e com mães menos escolarizadas e o oposto, para a especificidade e o valor preditivo negativo. CONCLUSÕES: Perguntas sobre higiene bucal respondidas pelas mães de crianças não são boas substitutas do padrão real de higiene bucal medido por meio do exame clínico bucal de placa dental.

Patterns of dental service use among homeless people using a targeted service

OBJECTIVE

The objective of this study was to describe the patterns of dental service use among homeless people using a targeted dental service from 1992 to 2001.

METHOD

A case-note review of a selection of patients (n = 204) was undertaken using a pre-designed data abstraction form.

RESULTS

For those presenting at their first contact, 40 percent (n = 68) expressed need in relation to oral pain and disease/tissue damage, and 28 percent (n = 33) in relation to dental checking and oral prophylaxis. Most homeless people had normative need for dental treatment (93 percent: n = 153). The dental service was delivered using a mix of outreach and fixed site clinics, with 75 percent (n = 153) of all first contacts made at outreach clinics. The targeted service was moderately successful at getting people to attend the fixed site service for continuing care, with 51 percent (n = 87) attending for subsequent visits. Location of first contact with the targeted dental service did not predict subsequent attendance. Those who did attend for further care tended to have normative needs for periodontal disease and dental decay and have their presenting complaint met. Only 23 percent (n = 46) of people completed a treatment plan, over a mean of 8.2 (standard deviation +/- 9.4) visits. No factors appeared to predict completion of treatment.

CONCLUSIONS

While the small sample limits the findings in this study, it is hypothesized that the presence of the dental service promoted uptake of dental care. Flexible attendance tended to result in multiple visits and delayed outcomes, which themselves could have acted as barriers to care.

Dental health of community-living older people attending secondary healthcare: a cross-sectional comparison between those with and without diagnosed mental illness

BACKGROUND

Mental illness and cognitive impairment are risk factors for poor dental health.

METHODS

We conducted a cross-sectional study to compare the dental health of older patients attending out-patient clinics and day hospitals of old age psychiatry services (the psychiatry group, n = 103) with those attending general/geriatric medical services (the medical group; n = 99). Those living in care homes, and those with diagnosed mental illness (in the medical group) were excluded. A registered mental health nurse assessed mental and general health using validated and previously published instruments. A registered dentist made an independent assessment of dental health (examination to assess oral pathology, status of remaining teeth, and dentures) and made an overall judgment about whether the patient needed any dental treatment (a "normative" need).

RESULTS

The normative need for dental treatment was significantly higher among the psychiatry group compared to the medical group (85% vs 52%; p<0.001); even after taking account of the effect of age, gender, teeth status, physical comorbidity, cognition, depressive symptoms, and overall mental and social health [adjusted odds ratio, OR (95% confidence interval): 4.32 (2.09, 8.91)]. The presence of any natural remaining teeth [OR: 4.44 (2.10, 9.42)] and Barthel Index [OR: 0.96 (0.93, 0.99)] were the two other independent predictors of the need for treatment.

CONCLUSION

Dental problems are common in community-living older people, especially those with some natural remaining teeth and those with mental illness. There is a need to develop integrated mental health and dental care services for older people with emphasis on prevention of dental problems.

Polarization of dental caries among individuals aged 15 to 18 years

Objective:

To evaluate the role of socioeconomic variables and self-perceived oral health in the polarization of caries among adolescents in Santa Bárbara D'Oeste, Brazil.

Material and Methods:

Cross-sectional study. Sampling was randomized and sample size was defined according to WHO criteria. Two hundred and seventy seven adolescents (15 to 18 year-old) were examined by five trained examiners that assessed DMFT index according to WHO criteria. Self-perceived oral health, access to dental services and socio-demographic variables were self-reported. Student's t tests, chi-square tests, and multivariate logistic regression (with significant caries index (SiC) as the outcome), were performed.

Results:

Mean DMFT was 5.48 (±4.22) and the proportion of "caries free" subjects was 15.5%. Mean DMFT (9.71±2.85) and mean D (1.67±2.18) of SiC positive subjects were significantly higher than mean DMFT (2.88±2.17) and mean D (0.45±0.87) of SiC negative subjects (p<0.0001). Mean D of white (0.76±1.51) was significantly smaller than mean D of non-white subjects (1.32±2.01). The only variable independently associated with the "SiC positive" outcome was "report of toothache within six months prior to the study" [OR=1.83 (95%CI 1.08 to 3.12)], p<0.001.

Conclusion:

SiC was associated with "report of toothache" but not with sociodemographic variables in the studied population.

Are immigrant populations aware about their oral health status? A study among immigrants from Ethiopia

Background

Evidence from Western countries indicates that there are fundamental discrepancies between self-perceived illness of immigrants and the provision of health care, according to the Western bio-medical health service model. These need to be understood in the planning and implementation stages of public health care programs for new immigrants. The objectives of the present study were to investigate self-perceived versus clinically diagnosed dental and periodontal health status among immigrants from Ethiopia.

Methods

During 2004–2005, dental and periodontal health status was recorded among 340 Ethiopian immigrants, utilizing the DMFT and CPI indices. Additionally, participants were interviewed using a questionnaire which included perceived dental and periodontal health status. Sensitivity and specificity levels of this perception were calculated and compared with the published scientific literature.

Results

Regarding dental caries, according to the three operational cut-off points, sensitivity ranged from 70% to 81%, and specificity ranged from 56% to 67%. Regarding periodontal status, 75% of the subjects clinically diagnosed with periodontal pockets self-perceived a "bad" health status of gums (sensitivity) and 54% of the subjects diagnosed without periodontal pockets, reported a "good" health status of gums (specificity). These indications of perception levels were higher than a previous study conducted among native born Israelis.

Conclusion

Minority ethnic groups should not be prejudicially regarded as less knowledgeable. This is illustrated by the unexpected high level of oral health status perception in the present population. Oral health promotion initiatives among immigrants should be based upon optimal descriptive data in order to accomplish the inherent social commitment to these diverse populations.

Factors associated with oral problems among adults with spinal cord injury

OBJECTIVE

To explore factors associated with self-reported current oral (tooth and gum) problems and oral pain in the past 12 months among adults with spinal cord injury.

METHODS

An online oral health survey on the South Carolina Spinal Cord Injury Association website. Respondents were 192 adult residents of the US who identified themselves as having spinal cord injury at least 1 year before the survey date.

RESULTS

Approximately 47% of respondents reported having oral problems at the time of the survey, and 42% reported experiencing oral pain in the 12 months before the survey date. Multiple predictor analyses (controlling for age, gender, income, and dental insurance) indicated that current oral problems were positively associated with dry mouth symptoms, financial barriers to dental care access, smoking, and paraplegia. Oral pain experienced in the past 12 months was positively associated with dry mouth symptoms, financial barriers to dental care access, minority race, and paraplegia.

CONCLUSIONS

Adults with spinal cord injury reported a high prevalence of oral problems and oral pain. Those with paraplegia were more likely to report problems than those with tetraplegia. Because dry mouth and smoking were significantly associated with these problems, patient education from both dental and medical providers should emphasize awareness of the side effects of xerostomia-causing medications, dry mouth management, and smoking cessation. Findings also indicate unmet needs for low-cost preventive and treatment dental services for this vulnerable population.

Reproducibility and validity of self-perceived oral health conditions

The reproducibility and validity of self-perceived periodontal, dental, and temporomandibular joint (TMJ) conditions were investigated. A questionnaire was applied in interview to 200 adults aged from 35 to 44, who were attending as casual patients at Araraquara School of Dentistry, São Paulo State University, São Paulo, Brazil. Clinical examination was based on the guidelines of the World Health Organization manual. The interview and the clinical examination were performed in two occasions, by a calibrated examiner. Reproducibility and validity were, respectively, verified by kappa statistics (kappa) and sensitivity (Sen) and specificity (Spec) values, having clinical examination as the validation criterion. The results showed an almost perfect agreement for self-perceived TMJ (kappa = 0.85) and periodontal conditions (kappa = 0.81), and it was substantial for dental condition (kappa = 0.69). Reproducibility according to clinical examination showed good results (kappa = 0.73 for CPI index, kappa = 0.96 for dental caries, and kappa = 0.74 for TMJ conditions). Sensitivity and specificity values were higher for self-perceived dental (Sen = 0.84, Spec = 1.0) and TMJ conditions (Sen = 1.0, Spec = 0.8). With regard to periodontal condition, specificity was low (0.43), although sensitivity was very high (1.0). Self-perceived oral health was reliable for the examined conditions. Validity was good to detect dental conditions and TMJ disorders, and it was more sensitive than specific to detect the presence of periodontal disease.

Clinical correlates of oral health-related quality of life: evidence from a national sample of British older people

This study investigated the relationships between an oral health-related quality of life (OHRQoL) indicator and specific clinical dental measures, in a national representative sample of the British older population. A random subsample was drawn from the free-living sample of the National Diet and Nutrition Survey (people aged >or= 65 yr). This subsample consisted of 407 dentate and 346 edentate participants, who were clinically examined and interviewed. The OHRQoL was assessed through the Oral Impacts on Daily Performance (OIDP) indicator. After adjusting for age, gender, and education, dentate subjects with up to 8 occluding pairs of teeth were 2.66 [95% confidence interval (CI): 1.08, 6.51) times, and those with up to 2 anterior occluding pairs were 3.00 (95% CI: 1.55, 5.81) times, more likely to report oral impacts when compared with those having more occluding pairs of teeth. Edentate participants with inadequate denture adaptation were 1.92 (95% CI: 1.04, 3.53) times, and subjects with inadequate denture retention were 2.04 (95% CI: 1.13, 3.69) times, more likely to report oral impacts than the remaining edentate sample in each case. OHRQoL in older British people is significantly related to the number of occluding pairs of natural teeth among the dentate and denture quality among the edentate.

Factors associated with dental health care coverage in Mexico: findings from the National Performance Evaluation Survey 2002?2003

OBJECTIVES

To determine the level of dental health care coverage in people aged > or =18 years across the country, and to identify the factors associated with coverage.

MATERIAL AND METHODS

Using the instruments and sampling strategies developed by the World Health Organization for the World Health Survey, a cross-sectional national survey was carried out at the household and individual (adult) levels. Dental data were collected in 20 of Mexico's 32 states. The relationship between coverage and environmental and individual characteristics was examined through logistic regression models.

RESULTS

Only 6098 of 24 159 individual respondents reported having oral problems during the preceding 12 months (accounting for 14 284 621 inhabitants of the country if weighted). Only 48% of respondents reporting problems were covered, although details of the appropriateness, timeliness and effectiveness of the intervention(s) were not assessed. The multivariate regression model showed that higher level of education, better socioeconomic status, having at least one chronic disease and having medical insurance were positively associated with better dental care coverage. Age and sex were also associated.

CONCLUSIONS

Overall dental health care coverage could be improved, assuming that ideal coverage is 100%. Some equality of access issues are apparent because there are differences in coverage across populations in terms of wealth and social status. Identifying the factors associated with sparse coverage is a step in the right direction allowing policymakers to establish strategies aimed at increasing this coverage, focusing on more vulnerable groups and on individuals in greater need of preventive and rehabilitative interventions.

Can Oral Health-Related Quality of Life Measures Substitute for Normative Needs Assessments in 11 to 12-year-old Children?

OBJECTIVES

1) assess the relationship between a measure of condition-specific oral health-related quality of life (OHRQoL) and the related normative need for dental treatments, and 2) test the diagnostic validity of the condition-specific OHRQoL measure for specific dental conditions in a group of primary school children.

METHODS

A cross-sectional study of all 11 to 12 year-olds carried out in a municipal area of Suphanburi province, Thailand. 1034 children (91.8%) were dentally examined to assess their normative needs for 6 types of treatment (dental caries, traumatic dental injuries, enamel defects, periodontal, orthodontic and prosthodontic treatment). OHRQoL was assessed using the Child-OIDP index and its Condition-Specific impacts measure for the 6 treatment types.

RESULTS

The prevalence of specific types of normative needs ranged from 3.2% (prosthodontic) to 97.0% (periodontal) and for Condition-Specific oral impacts from 0.7% (prosthodontic) to 50.6% (dental caries). Despite their statistically significant relationship for every treatment type except for periodontal treatment when need was indicated by a CPI score of 1, there were large differences between measures of normative need and oral impacts. High proportions of children had normative need without impacts and vice versa. The biggest differences were for appearance-related conditions (e.g. enamel defects and orthodontic treatment). For every type of treatment, oral impacts poorly predicted the normative needs of individuals.

CONCLUSIONS

Although normative needs and OHRQoL are associated, when assessed appropriately, there was considerable discrepancy between them. OHRQoL measures cannot replace normative needs. Instead, both should be used in combination in order to cover different dimensions of oral health.

The relationship between cigarette smoking and perceived dental treatment needs in the United States, 1988–1994

BACKGROUND

Although factors affecting perceived dental treatment needs have been investigated, the effect of smoking status on perceptions of dental needs has not been examined.

METHODS

The authors examined data on 13,227 dentate people aged 20 to 79 years from the Third National Health and Nutrition Examination Survey (NHANES III). Information was collected information on sociodemographic characteristics, cigarette smoking, perceived dental treatment needs and other factors during a home interview, and clinical oral health information was collected at a mobile examination center.

RESULTS

In univariate analyses, current smokers were more likely than nonsmokers to perceive dental needs in all categories, except for the need for a dental cleaning. Multivariate regression results indicate that current smokers were more likely to report a need for periodontal treatment and dental extractions compared with nonsmokers (odds ratio [OR] = 1.40; 95 percent confidence interval [CI] = 1.05-1.87 and OR = 1.61; 95 percent CI = 1.22-2.14, respectively). The authors found an interaction between smoking and race/ethnicity in models describing the need for teeth to be filled/replaced and for orthodontic/cosmetic work.

CONCLUSIONS

Current smokers were more likely to have more perceived dental needs compared with nonsmokers. Practice Implications. These results may be important for the advancement of efforts directed toward tobacco-use cessation programs and to understand factors that could affect dental care utilization.

Relationship between traumatic dental injuries and attention-deficit/hyperactivity disorder in children and adolescents: proposal of an explanatory model

The objective of the present study was to determine the association between attention-deficit/hyperactivity disorder (ADHD) and traumatic dental injuries in a child psychiatric clinical population in Istanbul. A total of 475 consecutive children aged 8-17 years were enrolled in the study. Children and their parents were interviewed about the presence of traumatic dental injury and if a positive response was obtained further questions were inquired regarding the time and cause of the injury, and whether treatment had been sought. Child psychiatric diagnosis was based on Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV) criteria. Of the 475 children, 32 reported a traumatic dental injury (6.7%) with statistically significant association with ADHD (chi(2) = 26.90, d.f. = 1, P = 0.0001; odds ratio = 17.41, 95% CI: 4.11-73.55). On the Conners Teacher Report Questionnaire, children with dental trauma group differed significantly from the non-ADHD group but not from the ADHD group (F = 17.02, d.f. = 2, P = 0.0001). Among children with ADHD and dental fracture, the most common subtype was combined ADHD (90%). This is the first study describing a significant association between dental fractures and ADHD which contributes to an explanatory model on dental traumas among children. According to us, awareness of this association is essential at child psychiatry and pediatric dentistry settings and we recommend preventive efforts to be directed at the treatment of ADHD.

Use of Clinical Services Compared with Patients' Perceptions of and Satisfaction with Oral Health Status

OBJECTIVES

To examine the relationship between rates of clinical service use and self-reported perception of and satisfaction with oral health status.

METHODS

Dental services provision rates were calculated using health maintenance organization electronic data for members 55 years of age and older with at least four years of eligibility between 1990 and 2000. A mail survey yielded 986 responses (response rate = 65.7%). Poisson regression was used to examine the relationship between service utilization rates and self-reported perception of and satisfaction with oral health status, controlling for age, education, sex, and marital status.

RESULTS

Perceptions of oral health status and levels of satisfaction with oral health status generally were closely associated. Greater dissatisfaction with oral health status and perception of poorer oral health status were associated with higher usage of nonpreventive dental services. Less satisfaction with oral health status was associated with higher restorative services usage and lower preventive services usage and slightly associated with periodontal service usage. Perception of a less favorable oral health status was strongly associated with higher restorative and periodontal services usage, but had only a weak association with preventive services usage.

CONCLUSIONS

Dental plan members' service use is associated with their perception of their oral health status and their level of satisfaction with it. Future work should seek to clarify whether opinions on oral health status and satisfaction are a result of clinical experiences over time or whether the behavior and the values associated with seeking and obtaining care instead shape opinions on status and satisfaction.

Self - perceived and clinically diagnosed dental and periodontal health status among young adults and their implications for epidemiological surveys

BACKGROUND: Clinical (normative) and subjective (self-assessment) evaluation of caries and periodontal diseases have been reported to demonstrate a significant disparity. The dental public health team is obligated to recognize and understand this gap. The objectives of the study were to investigate the practical values of using questionnaires (self-perceived assessment) as compared to clinical examinations (normative assessment) and to evaluate the implications of the results in understanding the public's perception of oral health. METHODS: The investigation was performed on 4920, 21 year-old Israeli adults upon release from compulsory military service between 1996 and 1998. Participants were asked to fill in a questionnaire inquiring how they would rate their personal dental and periodontal health levels. Clinical examinations, employing the DMFT and CPITN indices, were performed to determine normative oral health status. Perceived and normative assessments were compared for sensitivity, specificity, positive and negative predictive values and overall proportions using the clinical examinations as a gold standard. RESULTS: The sensitivity (disease perception) for dental status was found to be 0.34, while the specificity (health perception) was found to be 0.83. The positive predictive value for perceived dental status was found to be 0.68, whereas the negative predictive value was found to be 0.54. The sensitivity for perceived periodontal status was found to be 0.28, while the specificity was found to be 0.83. The positive predictive value for perceived periodontal status was found to be 0.05, whereas the negative predictive value was found to be 0.97. Regarding the overall proportions, a large discrepancy was found between self-assessment and professional assessment for both dental and periodontal health status. CONCLUSIONS: Self-assessment questionnaires were of low value in evaluating oral health status both in the individual and public levels, though perception levels of health were higher than that of disease. Findings reflects a low level of awareness of the public that may influence care-seeking behavior and highlight the importance of oral health promotion and the crucial need for public health action.

Needs and demands for dental care in patients attending the University Dental Hospital in Sri Lanka

AIMS

To determine the needs and demands for dental care in patients visiting a university dental hospital.

DESIGN

A cross-sectional study of first visit patients.

SETTING

The University Dental Hospital in Peradeniya, Sri Lanka.

PARTICIPANTS

A total of 849 first visit patients.

METHODS

The main complaint of each patient was recorded and was considered as a measure of demand for dental care. Tooth based and orthodontic treatment needs were assessed using the WHO basic methods. Periodontal treatment need was assessed by the periodontal treatment needs system. Need for prosthetic care was also assessed.

RESULTS

Thirty per cent and 23% of patients demanded treatment for decayed teeth and toothache respectively. Nearly 34%, 27% and 17% of patients needed surgical, restorative and periodontal care respectively for the main complaint. Of those seeking care, 94% needed treatment other than what was required for the main complaint. The predominant normative treatment need was for periodontal care (77%) whilst 47% needed restorations or extractions.

CONCLUSION

Normative needs of patients demanding treatment were high and many had demanded treatment before acute symptoms had developed. However, delays in seeking care were evident. Further studies are needed to identify factors for delay in obtaining care.
