The use of a self-report questionnaire for dental health status assessment: a preliminary study

Predictors of orthodontic treatment preferences in a large representative UK adult cohort

Introduction The number of adults seeking orthodontic treatment globally continues to rise. This study aimed to clarify how demographic characteristics, treatment-related factors (perceived quality, cost, convenience), psychological factors (dental aesthetics, body image, mental health) and oral health influence adults' interest in pursuing orthodontic treatment.Methods A representative sample of 604 adults with the same proportion of participants as the national United Kingdom population across three core demographics (age, sex, ethnicity) completed an online survey. Data were analysed using chi-squared tests, multinomial logistic regressions, mixed analyses of variance and hierarchical multiple regression.Results A high proportion of respondents had at least some interest in pursuing orthodontic treatment and those with the greatest interest were also more likely to prefer that an orthodontist deliver this treatment. Individuals who reported a preference for an orthodontist (53% of respondents) identified treatment quality as the primary advantage and cost as the most common concern. For those who preferred direct-to-consumer aligners (25% of respondents), quality was the most common concern and convenience the primary advantage. Hierarchical multiple regression revealed that, while demographic control variables explained 10.96% of variance in respondents' interest in pursuing any type of orthodontic treatment, a model that included psychological variables and oral health explained substantial additional unique variance (20.61%; both ps <0.05). Greater negative psychosocial impact of dental aesthetics, better body image and good oral health each made significant unique contributions to predicting orthodontic interest.Conclusions These data provide a more nuanced and comprehensive understanding of the many distinct factors that influence interest in undertaking orthodontic treatment in the adult general population, with implications for ethical and consumer-centred marketing, as well as patient satisfaction and treatment adherence.

Low-cost and scalable machine learning model for identifying children and adolescents with poor oral health using survey data: An empirical study in Portugal

This empirical study assessed the potential of developing a machine-learning model to identify children and adolescents with poor oral health using only self-reported survey data. Such a model could enable scalable and cost-effective screening and targeted interventions, optimizing limited resources to improve oral health outcomes. To train and test the model, we used data from 2,133 students attending schools in a Portuguese municipality. Poor oral health (the dependent variable) was defined as having a Decayed, Missing, and Filled Teeth index for deciduous teeth (dmft) or permanent teeth (DMFT) above expert-defined thresholds (dmft/DMFT ≥ 3 or 4). The survey provided information about the students' oral health habits, knowledge, beliefs, and food and physical activity habits, which served as independent variables. Logistic regression models with variables selected through low-variance filtering and recursive feature elimination outperformed various others trained with complex machine learning algorithms based on precision@k metric, outperforming also random selection and expert rule-based models in identifying students with poor oral health. The proposed models are inherently explainable, broadly applicable, which given the context, could compensate their lower performance (Area Under the Curve = 0.64-0.70) compared to similar approaches and models. This study is one of the few in oral health care that includes bias auditing of classification models. The audit surfaced potential biases related to demographic factors such as age and social assistance status. Addressing these biases without significantly compromising model performance remains a challenge. The results confirm the feasibility of survey-based machine learning models for identifying individuals with poor oral health, but further validation of this approach and pilot testing in field trials are necessary.

Determinants of oral health among Iranian soldiers: a structural equation modeling study

BACKGROUND

Military personnel often face unique challenges in maintaining optimal oral health. This study investigated the oral health status, caries experience, and associated factors among a sample of Iranian soldiers, employing a structural equation modeling (SEM) approach to explore the complex interplay of socioeconomic and behavioral determinants.

METHODS

A cross-sectional study was conducted among 658 male soldiers aged 18-30 years from three military barracks in Fars province, Iran. Data were collected through a structured instrument and clinical oral examinations. The study employs the DMFT index, which measures caries experience based on decayed, missing, and filled teeth, along with the Simplified Oral Hygiene Index (OHI-S) to assess overall oral health status. Structural equation modeling was employed to analyze the complex relationships between socioeconomic factors, oral health behaviors, and oral health outcomes.

RESULTS

The mean DMFT score was 3.57 ± 5.91, and the mean OHIS score was 0.56 ± 1.42. SEM analysis revealed that socioeconomic status (SES) indirectly influenced DMFT and oral hygiene scores, mediated by drug use, oral hygiene practices, dietary sugar consumption, and dental visit frequency. Lower toothbrushing frequency was significantly associated with higher DMFT (Estimate = -0.064, p < 0.001) and OHIS scores (Estimate = -0.637, p < 0.001). Drug use (smoking, qalyan, alcohol) was linked to poorer oral health outcomes, while more frequent dental visits were associated with lower DMFT and OHIS scores.

CONCLUSION

This study reveals the complex interplay between socioeconomic conditions, oral health behaviors, and oral health outcomes among Iranian soldiers. The findings highlight the need for targeted interventions to address modifiable risk factors and improve access to preventive dental care within military settings. Future longitudinal studies are warranted to elucidate further the causal pathways between these factors and oral health outcomes in military populations.

Validation of an online version of the rapid estimate of adult literacy in dentistry-30 for use by medical and dental students in Nigeria

BACKGROUND

The need for online adaptations of research instruments became more pronounced amidst the COVID-19 pandemic. This study sought to modify the REALD-30 for online application (eREALD-30) and evaluate its content validity and internal reliability among medical and dental students in Nigeria.

METHODS

The eREALD-30 required participants to identify if each of the listed words were related to dentistry by ticking either a 'yes' or 'no' response with the option to mark 'don't know' for words they were unsure about. Scores ranged from 0 to 30. Five oral health experts reviewed the eREALD-30 for cultural appropriateness, while content validity was evaluated by 10 medical and dental students. Internal reliability was assessed with 320 students recruited from 15 medical and dental schools spanning the country's six geopolitical zones. These students also completed an oral health status assessment tool. Data collection utilized an online survey platform. Validity of the eREALD-30 was determined through correlation analysis between eREALD-30 scores and the oral health status assessment tool. Furthermore, binary logistic regression analysis was employed to explore the assocations between participants' oral health status and their oral health literacy, adjusting for age, sex, and level of medical and dental education.

RESULTS

Out of the respondents, 178 (55.6%) exhibited poor oral health literacy, while 205 (64.1%) reported having good oral health status. Those with good oral health literacy demonstrated significantly higher odds of having good oral health status (OR: 1.61; 95% CI: 1.02-2.54; p = 0.04). However, individuals with good oral health literacy had increased odds of good oral health status after adjusting for confounding factors,, though this association did not retain statistical significance (AOR: 1.39; 95% CI: 0.86-2.24; p = 0.17). The eREALD-30 displayed strong internal consistency (Cronbach alpha = 0.933), indicating its reliability in assessing oral health literacy levels, alongside a high content validity score of 0.90.

CONCLUSION

The study finding suggests that the e-version of the REALD-30 was reliable and valid for use among medical and dental students in Nigeria.

Predictors of oral health literacy in pregnant women

We determined factors associate with oral health literacy of pregnant women. A total of 203 pregnant women attending Hospital Universiti Sains Malaysia (USM) for antenatal care participated in this cross-sectional study. The Malay version of Oral Health Literacy Instrument (OHLI-M) and a structured self-administered questionnaire were used to obtain variables of interest. The mean OHLI-M score was 73.6 (SD 12.59). Only slightly more than half of our participants had adequate oral health literacy (54.2%), while others were marginal (31.0%) and inadequate (14.8%). Our findings revealed that women with adequate oral health literacy were more likely to be those with higher education qualification and were very satisfied or satisfied with their oral health status. The identification of these predictors highlighted the importance to keep oral health education messages simple and clear for the benefit of individuals with low educational attainment.

Oral Health Status of New Zealand Defence Force Recruits

INTRODUCTION

The demands of operational deployment mean that defense force personnel must be dentally fit. Although medical evacuation for dental causes should be avoided, dental emergencies are a major non-combat-related contributor to withdrawal from deployment. Information on the oral health status of recruits and officer cadets entering the New Zealand Defence Force (NZDF) is scarce, yet it is useful for service and workforce planning. We investigated oral health status and its associations in new recruits and officer cadets entering the NZDF over a 13-month period.

MATERIALS AND METHODS

This study used data from recruits' initial dental examination (including baseline forensic charting), posterior bitewing radiographs, orthopantomograph radiograph, and a socio-dental questionnaire. The impaction status of third molar teeth was evaluated. Ethical approval was obtained from the University of Otago Ethics Committee (reference number D18/200) and the NZDF Organisational Research Committee.

RESULTS

Of the 874 (83%) of the 1,053 recruits (age range 17-59 years) who participated, one in five were Māori. Nearly two-thirds were Army recruits. Caries prevalence was almost 70%. Mean Decayed, Missing, and Filled Teeth (DMFT) (3.0 overall) was higher among females and Māori. Few teeth were missing due to caries. Third molars were common, seen in 745 (88.3%). One in four maxillary third molars (but only one in six mandibular ones) had fully erupted. The most common type of impaction among mandibular third molars was the mesioangular type, followed by vertical, horizontal, and distoangular. Almost 60% of recruits had one or more potentially problematic third molars. The prevalence was highest in the youngest age groups, those of medium or low socioeconomic status and in Army or Navy recruits.

CONCLUSIONS

Recruits' oral health was acceptable, but potentially problematic third molars were common, indicating a need for careful assessment (and their possible removal) before operational deployment.

Dental anxiety and oral health following stroke: a pilot study

BACKGROUND

Oral health is often poorer in people living with acquired brain injury relative to non-clinical controls. However, although anxiety disorders become more common following stroke, no study to date has tested whether dental anxiety might contribute to stroke survivors' increased vulnerability to poorer oral health. This pilot study reports the first test of whether the anxiety disturbances that commonly present following stroke extend to dental anxiety, and if dental anxiety in this group is linked to poorer oral health.

MATERIALS AND METHODS

First-time stroke survivors (N = 35) and demographically matched controls (N = 35) completed validated measures of dental anxiety, oral health, negative affect, and life satisfaction.

RESULTS

Stroke survivors did not differ from controls in their overall levels of dental anxiety or oral health, but uniquely for the stroke group, dental anxiety was strongly associated with poorer oral health, and this effect remained significant even after controlling for negative affect and life satisfaction.

CONCLUSION

Stroke survivors who have higher levels of dental-related anxiety may be at increased risk of poorer oral health.

A cross-sectional study on dietary assessment, oral hygiene behavior, and oral health status of adolescent girls

Adolescents are a population group that is vulnerable to nutritional problems other than toddlers, especially young women. Special attention to the dietary issues of adolescent girls needs to be obtained along with the increase in the adolescent population in Indonesia because this affects the growth and development of the body and will impact adult nutrition problems. The purpose of the study was to analyze the relationship between diet assessment and oral health status of adolescent girls, the relationship between oral hygiene behavior and oral health status of adolescent girls, and the simultaneous relationship between dietary assessment and oral hygiene behavior with the oral health status of adolescent girls. Analytical research using the survey method was conducted on 96 young women in two junior high schools in Bandung. Assessment of diet seen from eating behavior and anthropometric examination. Eating behavior using the Adolescent Food Habit Checklist Index questionnaire and anthropometric investigations were carried out by looking at body height, body weight, and Mid Upper Arm Circumference using the standards from the Indonesian Minister of Health Regulation 2020. Oral hygiene behavior using the Oral Hygiene Behavior Index questionnaire. Oral health status using the Dental Health Status Assessment. The results were statistically analyzed with Spearman's Rank Correlation, and Multiple Linear Regression tests showed no significant relationship between dietary assessment and oral health status (eating behavior with a p-value = 0.429 and anthropometric examination with a p-value = 0.262). A significant association between oral hygiene behavior and oral health status, with a p-value of 0.003, while there is no simultaneous relationship between diet assessment and oral hygiene behavior with oral health status, with multiple r 2 = 13.2%.

Can health kiosks be used to identify oral health care needs? A pilot study

OBJECTIVE

The aim of this study was to investigate the reliability of digital imaging for detecting restorative treatment need among individuals in their 20s by comparing the outcome of digital imaging with clinical caries findings at the patient level.

MATERIAL AND METHODS

Five intraoral clinical daylight and digital fluorescence images were taken extraorally of 21 patients. A clinical examination was then performed by a trained and calibrated dentist. Additionally, the patients answered a multiple-choice questionnaire about their health habits. The images were analysed and caries findings were recorded. For statistical analysis, sensitivity and specificity were calculated. Results were shown as ROC curves and AUC values. All analyses were done using SPSS (version 24.0, Chicago, IL).

RESULTS

Caries lesions were most often detected in molars and least often in canines. When using the clinical status as gold standard, digital imaging gave an AUC value of 0.617, whereas the outcome by questionnaire gave an AUC value of 0.719. When using the combined outcome of digital imaging and the questionnaire, the AUC value was 0.694 with clinical validation.

CONCLUSIONS

It can be concluded that health kiosks may help to reduce the number of patients waiting for dental treatment; more specifically, the questionnaire with individual feedback may provide a new instrument for providing instructions for homecare online. However, the camera system must be developed further, and dentists and dental hygienists require training to analyse the images.

The impact of oral health status on COVID-19 severity, recovery period and C-reactive protein values

Objectives The oral cavity is a potential reservoir for respiratory pathogens which can predispose patients to bacterial super-infection. Several trials have correlated poor oral hygiene with hyper-inflammation. Similarly, COVID-19 severity has been linked to hyper-inflammatory responses. Hence, in this study, we assumed that increased COVID-19 severity may be linked to poor oral health status. This was achieved through assessing oral health status, severity of COVID-19 symptoms, C-reactive protein (CRP) levels and duration of recovery.Methods Cross-sectional study based on a questionnaire; 308 Egyptian patients with confirmed positive polymerase chain reaction (PCR) tests were included in the study after exclusion criteria. The questionnaire was designed with two sections: the first section for oral health evaluation and the second section for COVID-19 severity evaluation. Assessment of the effect of oral health on COVID-19 severity was performed using an oral health score. The effect of oral health on CRP and recovery period were evaluated as secondary endpoints. Data of CRP levels and COVID-19 PCR tests were collected via the questionnaire and confirmed by reviewing medical records.Results The correlation between oral health and COVID-19 severity showed a significant inverse correlation (p <0.001, r = -0.512). Moreover, the correlation between oral health with recovery period and CRP values also revealed a significant inverse correlation (p <0.001, -0.449 and p <0.001, -0.190, respectively), showing that poor oral health was correlated to increased values of CRP and delayed recovery period.Conclusions Our study provided some evidence that oral health could have a potential impact on the severity of COVID-19. However, the correlation is limited by the study design. A more substantial research project is required to address this relation.

Event-Based but Not Time-Based Prospective Memory Is Related to Oral Health in Late Adulthood

BACKGROUND

Most evidence now indicates that cognitive function is related to poorer oral health in late adulthood, but that this relationship is not invariant across specific cognitive domains. Prospective memory (PM) is a core memory skill that refers to memory for future intentions and is known to be related to the formation of habits such as tooth flossing. However, the relationship between PM and oral health has been subject to only limited empirical study.

OBJECTIVE

The two studies reported in this paper were designed to test whether PM is related to oral health in older adults of varying vulnerability status.

METHODS

Study 1 sampled community-dwelling older adults (N = 172) living independently in the community; Study 2 sampled older adults living in a retirement village (N = 32). Participants in both studies were asked to complete a behavioural measure of PM, with their oral health indexed via self-report (Study 1) or an objective oral health exam (Study 2).

RESULTS

In both studies, relationships emerged between event-based PM and oral health, with Study 2 showing that these relationships were specific to oral health measures of plaque and calculus.

CONCLUSIONS

Older adults are particularly vulnerable to dental pathology, with important implications for their broader health and well-being. By showing that there is a relationship between oral health and a particular type of PM, this work will have potential implications for the development of more effective interventions focused on enhancing oral health outcomes in this group, such as those focused on strengthening habit formation.

Association between Perceived Oral Symptoms and Presence of Clinically Diagnosed Oral Diseases in a Sample of Pregnant Women in Malaysia

The integration of oral health into primary health care denotes the important role of medical counterparts as the front liners in antenatal care to help screen mothers for oral symptoms and refer them to dentists accordingly. However, the validity of self-perceived oral health status is inconclusive. This study determined the association between self-perceived oral symptoms and the presence of clinically diagnosed oral diseases in a sample of pregnant women. A total of 192 pregnant women participated in this cross-sectional study. Clinical oral examinations were performed to record dental caries experience, gingival health and periodontal health. The women were also asked about their oral symptoms. Most women had at least one oral symptom (84.9%): cavitated tooth (62.0%), bad breath (38.5%), bleeding gums (28.6%), and toothache (22.9%). About half of the women had untreated dental caries (58.9%), and the odds were significantly higher in women who complained of having cavitated tooth. About half of the women had moderate to severe gingivitis (53.7%), and the odds were significantly higher in women who complained of bleeding gums. About half had periodontal pockets (46.3%), and the odds were higher in women who complained of bleeding gums and bad breath although lower in women who complained of swollen gums. In conclusion, the prevalence of dental caries and periodontal disease among pregnant women in this study were relatively high. The presence of untreated dental caries, moderate and severe gingivitis, and periodontal pockets were significantly associated with their corresponding oral symptoms.

Oral microbiome composition, but not diversity, is associated with adolescent anxiety and depression symptoms

PURPOSE

Depression and anxiety are highly prevalent disorders, whose significant burden is compounded by the presence of oral disease. Mental health disorders and oral health may be associated via changes to the oral microbiome, involving increased pro-inflammatory communication and cortisol in saliva. The present study provides the first culture-independent investigation of the oral microbiome considering depression and anxiety symptoms in adolescence, a critical age where these conditions begin to emerge and co-occur. It also investigates whether inflammation and cortisol moderate these relationships.

METHODS

Participants (N = 66) aged 14-18 years (69.70% female) self-reported oral health, depression and anxiety symptoms, and collected saliva samples across two days. Saliva was assayed for cortisol and C-reactive protein (CRP), and used for 16S rRNA gene sequencing to estimate the oral microbiome. Multivariate statistical analyses examined associations.

RESULTS

Overall diversity of the oral microbiome did not differ between adolescents by anxiety or depression grouping (low versus high symptoms), and was not associated with symptom measures. Depression and anxiety symptoms were instead associated with differential abundance of specific bacterial taxa, including Spirochaetaceae, Actinomyces, Treponema, Fusobacterium and Leptotrichia spp. Several host mood-microbial relationships were moderated by proposed mechanisms, including salivary cortisol and CRP.

CONCLUSIONS

Oral microbiome composition, but not diversity, was associated with adolescent anxiety and depression symptoms. Longitudinal studies considering these associations would improve mechanistic understanding. This research indicates that adolescence remains an essential developmental period to identify early targets for intervention.

Development of toolkits for detecting dental caries and caries experience among children using self-report and parent report

OBJECTIVES

To develop child- and parent-reported toolkits for active caries and caries experience in children and adolescents, ages 8-17.

METHODS

A sample of 398 child/parent dyads recruited from 12 dental practices in Los Angeles County completed a computer-assisted survey that assessed oral health perceptions. In addition, children received a dental examination that identified the presence or absence of active caries and caries experience. A Multiple Adaptive Regression Splines model was used to identify a subset of survey items associated with active caries and caries experience. The splines and coefficients were refined by generalized cross-validation. Sensitivity and specificity for both dependent variables were evaluated.

RESULTS

Eleven child self-reported items were identified that had sensitivity of 0.82 and specificity of 0.45 relative to active caries. Twelve parent-reported items had a sensitivity of 0.86 and specificity of 0.50. Seven child self-reported items had a sensitivity of 0.86 and specificity of 0.34, and 11 parent-reported items had a sensitivity of 0.86 and specificity of 0.47 for caries experience.

CONCLUSIONS

The survey items identified here are useful in distinguishing children with and without active caries and with and without caries experience. This research presents a path towards using children's and their parents' reports about oral health to screen for clinically determined caries and caries exposure. The items identified in this study can be useful when clinical information is unavailable.

Out-Of-Pocket Expenditures on Dental Care for Schoolchildren Aged 6 to 12 Years: A Cross-Sectional Estimate in a Less-Developed Country Setting

Aim: The objective of this study was to estimate the Out-Of-Pocket Expenditures (OOPEs) incurred by households on dental care, as well as to analyze the sociodemographic, economic, and oral health factors associated with such expenditures. Method: A cross-sectional study was conducted among 763 schoolchildren in Mexico. A questionnaire was distributed to parents to determine the variables related to OOPEs on dental care. The amounts were updated in 2017 in Mexican pesos and later converted to 2017 international dollars (purchasing power parities-PPP US $). Multivariate models were created: a linear regression model (which modeled the amount of OOPEs), and a logistic regression model (which modeled the likelihood of incurring OOPEs). Results: The OOPEs on dental care for the 763 schoolchildren were PPP US $53,578, averaging a PPP of US $70.2 ± 123.7 per child. Disbursements for treatment were the principal item within the OOPEs. The factors associated with OOPEs were the child's age, number of dental visits, previous dental pain, main reason for dental visit, educational level of mother, type of health insurance, household car ownership, and socioeconomic position. Conclusions: The average cost of dental care was PPP US $70.2 ± 123.7. Our study shows that households with higher school-aged children exhibiting the highest report of dental morbidity-as well as those without insurance-face the highest OOPEs. An array of variables were associated with higher expenditures. In general, higher-income households spent more on dental care. However, the present study did not estimate unmet needs across the socioeconomic gradient, and thus, future research is needed to fully ascertain disease burden.

Validity of the self-reported number of teeth in Chilean adults

Background

Clinical dental evaluations are considered complex and costly measurements that epidemiological surveillance studies of multiple simultaneous chronic diseases currently require, for example National Health Surveys (ENS). Accordingly, simpler and more affordable methods need to be validated. The aim of this study was to assess the validity of the self-report on the total number of teeth in the general Chilean adult population.

Methods

A substudy was conducted on ENS 2016–2017 participants. A stratified random sample of 101 of them was subjected to a telephone questionnaire. This information was then compared with the results obtained from the oral examination performed by a trained nurse during a home visit. Spearman correlations, intraclass correlation coefficients and the Bland-Altman method were used to analyse the data.

Results

In men, the average number of teeth recorded during the oral examination coincided with the number of teeth in the self-report (22 teeth). In women, the total teeth average was 18 and 19 teeth according to the examination and self-report, respectively. For the total number of participants, a strong and significant Spearman correlation was obtained (ρ = 0.93); in men and women, the Spearman correlation observed was also strong and significant (ρ = 0.90 and ρ = 0.96 respectively). The value of the intraclass correlation coefficient indicated a significant concordance (CCI = 0.96) in both men and women (CCI = 0.93 and 0.98 respectively). A tendency to greater correlation was observed as the number of teeth decreased.

Conclusions

The number of teeth self-reported by the subjects in this study correlated with the number of teeth recorded in the clinical examination. Self-report is a valid method to determine the number of teeth in national health surveys.

Perceived and Assessed Dental Treatment Needs of Schoolchildren in Benoe Division, Cameroon

Introduction:

Oral health surveys combining clinical and subjective measures are effective to inform oral health policy, practice, and evaluation of oral health interventions. However, only a few studies have examined the agreement between these measures in developing countries.

Objectives:

This study investigates dental treatment needs among Cameroon’s schoolchildren; specifically, we aim to estimate the extent to which perceived and clinical measures are in agreement.

Methods:

Using a multistage sampling technique, we randomly selected 11 schools and their pupils to participate in this study. We conducted an oral clinical examination using a mouth mirror and blunt probe in a classroom to evaluate children’s oral health. In addition, the participants filled out a questionnaire on sociodemographic characteristics, oral health behavior, and perceived treatment needs. To fulfill our aims, we use descriptive statistics and unconditional logistic regression.

Results:

Out of 700 children invited to participate, 692 completed the study (98.8%). The mean age of the children was 11.45 y (SD = 1.21), and there were slightly more boys ( n = 366, 52.9%) than girls ( n = 326, 47.1%). The majority of the children (85.2%) felt that their oral health was good, and more than half (53.2%) reported a perceived need for dental treatment. While 68.2% ( n = 472) had at least 1 objective treatment need, only 65.8% of them perceived this need, indicating a medium level of sensitivity (65.9%, 95% CI = 61.4% to 70.2%). In addition, we observed a high positive predictive value (84.5%, 95% CI = 80.4% to 88.1%) for perceived treatment need to detect clinically evaluated dental treatment need.

Conclusion:

Our findings show that perceived treatment has a high positive predicted value to determine clinical treatment need. Subjective assessment of treatment need may be an alternative low-cost option to help policy makers to design oral health interventions for Cameroonian children.

Knowledge Transfer Statement:

This study illustrates the potential of schoolchildren in a low-income country to make a good prediction of their dental treatment needs. The majority of these countries lack the human and material resources to conduct oral health surveys that include clinical assessment of treatment needs. Therefore, stakeholders can rely on data from self-administered oral health surveys to inform policy and delivery of services to schoolchildren in resource-limited settings.

Association between Dental Health and Osteoporosis: A Study in South Indian Postmenopausal Women

AIM

This study aims to objectively assess the dentition status in South Indian postmenopausal women and compare the dental health of osteoporotic participants with nonosteoporotic individuals.

MATERIALS AND METHODS

A total of 150 consecutive ambulatory South Indian postmenopausal women (>50 years of age) were assessed for their dental health using an internationally validated scoring system. Bone mineral density (BMD) was assessed using a dual-energy X-ray absorptiometry scanner.

RESULTS

About 39% of the participants were found to have osteoporosis and 23% had osteopenia at any site. More than half of them (57%) had poor dental health, and the predominant problems were cavities (43.5%) and loss of teeth (75%). Among 112 women who had tooth loss, the mean tooth loss was 4.8. The mean tooth loss among patients with normal BMD was 1.09 ± 1.2, in osteopenia was 2.1 ± 2, and in osteoporosis was 5.4 ± 2.8 (P < 0.01). The odds of having osteoporosis among the patients with three or more tooth loss were found to be 4.2 (95% confidence interval = 2.4-7.3).

CONCLUSION

Postmenopausal women with osteoporosis had significantly higher number of tooth loss. Tooth loss may thus be used as a surrogate marker to predict osteoporosis.
