Objective

Utility values enable relative comparisons across various health conditions, providing information for efficient allocation of healthcare resources. This study aimed to (1) quantify the utility values attributable to oral health-related quality of life (OHRQoL) in Japanese adults and (2) develop models for converting the 14-item Oral Health Impact Profile (OHIP-14) scores into EuroQoL 5-dimension 5-level (EQ-5D-5L)-based utility values.

Methods

This was a cross-sectional study. Data from a large-scale Internet survey of Japanese adults conducted in 2022 (n = 28 405; mean age 48.2 years) were analysed. Multiple linear regression models were fitted to investigate the association between OHIP-14 scores and EQ-5D-5L-based utility values, adjusting for confounders. Conversion models were developed using a random half of the participants, and the observed and predicted utility values in the other half were compared to evaluate the model performance.

Results

Among the participants, 55.2% scored 0, 20.9% scored 1–5 and 23.9% scored 6–56 on the OHIP-14, corresponding mean utility values of 0.93, 0.90 and 0.84, respectively. A one-point increase in the OHIP-14 score was associated with a lower utility value (coefficient: −0.0053; 95% confidence interval:health-related quality of life −0.0056, −0.0051). The estimated utility value attributable to OHIP-14 was −23.3 per 1000 individuals, greater than that for other prevalent chronic conditions, including hypertension and diabetes (−2.9 and −7.1 per 1000 individuals, respectively). The conversion model incorporated the OHIP-14 total score, age, sex and self-rated health, predicted utility scores on average and captured differences according to the number of teeth lost. However, there was a discrepancy between predicted and observed utility values in the lower utility value groups.

Conclusion

OHRQoL substantially impacted utility values at the population level. The OHIP-14 holds the potential as a valuable tool for predicting average utility values based on oral health conditions; however, the prediction performance was relatively low for individuals with a lower health-related quality of life.

Objectives

Oral health during the perinatal period and beyond affects the health and well-being of women and their offspring. Oral self-care behaviours can maintain or improve oral health; depression or stress during the perinatal period may compromise these behaviours. The aim of the study was to investigate the independent and combined effects of depression and stress on oral self-care behaviours of perinatal women in Appalachia, given the high burden of oral disease in this region.

Methods

A total of 1172 women in the first or second trimester of pregnancy were enrolled in the Center for Oral Health Research in Appalachia, cohort 2 (COHRA2) in West Virginia or Pittsburgh, Pennsylvania. Participants completed the Center for Epidemiological Studies Depression Scale, Perceived Stress Scale-10, and self-report items about oral self-care behaviours (i.e. toothbrushing and flossing) during pregnancy and five times in the 2+ years following birth. A Generalized Estimating Equation approach was used to analyse the longitudinal data.

Results

Maternal depression and stress were independently negatively related to toothbrushing and flossing frequency. These findings for toothbrushing were more pronounced in those with high levels of depression and high levels of stress, so there were both independent and combined effects. Frequency of toothbrushing and flossing stayed constant over time, so time was not associated with outcomes. About three-fourths of the sample reported toothbrushing levels that are consistent with established guidelines (i.e. two times daily), but almost half of the participants had very low levels of flossing (i.e. once or less a week).

Conclusion

Interventions targeting stress and depression throughout the perinatal period might be helpful in improving oral self-care behaviours and oral health among women in Appalachia, in addition to the benefit of decreasing emotional distress.

Objectives

To assess the prevalence of non-utilization of dental care in Lebanon and associated socioeconomic factors and self-care behaviours.

Methods

A nationwide, quantitative, survey-based study was conducted by trained interviewers with Lebanese residents aged ≥18 years between July and September 2019. Univariate analyses were performed using Pearson Chi Square test or the Fisher's exact test followed by a binary logistic regression using the SPSS Version 25.

Results

Of the 1070 participants, 247 (23.1%) did not utilise any type of healthcare and 144/247 (58.3%) did not utilise dental care. The prevalence of non-utilization of dental care was estimated at 13.5%. Only 4.7% of the respondents consulted their dentist in the past year, among which 53% cited pain/emergencies as the reason for their consultation. Socioeconomic factors associated with the non-utilization of dental care were lack of social medical insurance (OR, 0.49 [95% CI, 0.31 to 0.79]) and long waiting time/patient time restriction (OR, 2.05 [95% CI, 1.26 to 3.35]). On the other hand, facilitators for utilization of dental care included ethical standards/personal qualities of the dentist (OR, 0.53 [95% CI, 0.32 to 0.88]) and convenient cost with respect to the individual's economic status (OR, 0.28 [95% CI, 0.18 to 0.43]).

Conclusion

This study suggests that dental care practices in Lebanon, including the non-utilization of dental care, are suboptimal. Measures such as reducing sugar and tobacco consumption, providing information on oral hygiene, and using fluoride products are inexpensive; however, implementing these measures may take substantial time and input by multiple stakeholders.

Background and Rationale

Dental care systems have the potential to influence population oral health and patterns of socioeconomic inequalities. Therefore, understanding the impact of the ways in which countries fund, provide, and organize their dental care services is key in the analysis of determinants of oral health. In this commentary we offer a synopsis of recent typologies of healthcare systems, based on a rapid review, and highlight that none of them fit dental care services given the separation of dental care from general healthcare provision in many countries. The paper also summarizes evidence on dental care systems as determinants of population oral health and argues why a new typology of dental care systems is needed.

Challenges and Ways Forward

We argue that a typology must consider institutional arrangements, structures, and processes behind the provision of dental care, and that specific dimensions/variables that inform the typology should result from a process of discussion and consensus. Some methodological considerations for developing typologies are also discussed, including the challenges in the collection and analysis of data followed by an advanced cluster analysis. Despite their limitations, typologies have evolved into an essential tool for comparing the similarities and differences of healthcare systems across countries. Therefore, a dental specific typology for health systems will be useful for researchers, policymakers, and dental professionals to characterize the provision of dentalcare services in different countries. This will also enable examining their potential role as determinants of population oral health and inequalities.

Objectives

There is little data on the oral health conditions of Somali children. The aim was to assess the dental caries status and related risk factors of 12-aged children in primary schools in Hargeisa, Somaliland.

Methods

A school-based survey was conducted in Hargeisa in December 2022. Using 2-stage cluster sampling, 405 children (12-aged) were randomly selected from 16 primary schools. Data collection involved WHO structured interviewer-administered questionnaire and clinical examinations. The DMFT index was measured according to WHO criteria, and accordingly, the mean for the significant caries index (SiC) was calculated. The association between the DMFT and the relevant variables was analysed using negative binomial regression in STATA.

Results

The overall prevalence of dental caries was found to be 62.7%, with a mean DMFT of 1.7 and a SiC score of 3.7. Non-public school pupils showed significantly higher prevalence of dental caries and mean DMFT compared to public school counterparts (68.5% vs. 58.6%) and (1.91 vs. 1.48), respectively. Merely 14.7% of the participants utilized dental care services in the previous year. The multivariable analysis showed a significant positive association of the DMFT outcome with attending a non-public school (95% CI 1.16–2.12) and having many previous dental visits (95% CI 1.22–2.83). In the adjusted model, fathers of low education had children with better dental caries status (lower mean DMFT) than their well-educated counterparts. The mean DMFT was not significantly influenced by the factors sex, location, educational attainment (school class of the participants) and frequency of teeth cleaning.

Conclusion

Although the overall mean DMFT of school children in Hargeisa could be regarded low, the high levels of untreated caries especially in the one-third most affected are a cause for concern. Children enrolled in non-public schools formed the high-risk group. Preventive oral public health programs targeting Somali school children are recommended.

Objectives

The Toddler Oral Health Intervention (TOHI) was launched in 2017 to promote oral health prevention at well-baby clinics, with a focus on parents with children aged 6–48 months. This study aims to evaluate the integrity of motivational interviewing (MI) as one of the core intervention pillars in the TOHI study.

Methods

The TOHI study was conducted at nine well-baby clinics in the central and southern regions of the Netherlands, with 11 trained oral health coaches (OHCs) delivering a tailored individual counselling programme. Audio recordings of counselling sessions were uploaded by the OHCs into an online portal for feedback and integrity evaluation purposes. A trained independent assessor evaluated MI integrity using the MITI 4.2.1 coding scale. IBM SPSS Statistics was used to analyse the data, with ratings on technical and relational components and behavior counts computed by adding up the scores and categorizing them into six key MI skills. Descriptive statistics, including frequencies, percentages and median scores with interquartile ranges, were calculated.

Results

The median ratings on the technical and relational components were 2.5 (IQR 2.0–3.5) and 3.5 (IQR 3.0–4.0) out of a maximum of 5, with 45% and 58% of recordings showing fair or good MI integrity, respectively. A median of 38% (IQR 25–55%) of complex reflections and a reflection-to-question ratio of 0.7 (IQR 0.4–1.0), with 47% and 24% of recordings showing fair or good MI integrity, respectively. Median counts of MI-adherent and non-adherent statements were 3.0 (IQR 2.0–5.0) and 0.0 (IQR 0.0–1.0), respectively. The duration of recordings and MI integrity varied among oral health coaches.

Conclusion

Overall, this study revealed that, while intensive training was provided, not all OHCs in the TOHI study met fair thresholds for MI integrity. These findings emphasize the necessity of ongoing training, reflection and support to achieve and maintain a fair or good level of MI integrity in clinical practice.

Objectives

To assess the prevalence and severity of periodontal disease of the Rohingya refugees and host community in Bangladesh.

Methods

An unpublished pilot was conducted for the sample size calculation. Two-stage cluster sampling method was used to select 50 participants from refugee camps and 50 from the host community. Structured questionnaire and periodontal examination were completed. Composite measures of periodontal disease were based on the World Workshop (WW) and Centers for Disease Control and Prevention-American Academy of Periodontology. Linear regression models, for clinical attachment level and periodontal pocket depth (PPD) and ordered logistic regression models, for composite measures, were fitted to test the association of periodontal measures and refugee status.

Results

Compared to the host community, a smaller percentage of refugees reported good oral health-related behaviours. Refugees exhibited lower levels of bleeding on probing but higher PPD, hence a higher proportion had severe stages of periodontitis.

As per the WW, prevalence of periodontal disease was 88% and 100% in the host and refugee groups, respectively. In the unadjusted models, refugees were three times more likely to have severe stages of periodontitis; this association was attenuated when adjusted for confounders (sociodemographic variables and oral health-related behaviours).

Conclusions

Prevalence of periodontitis was high both in the host community and refugees. The refugees exhibited a more severe disease profile. The oral health of both groups is under-researched impacting the response of the health system. Large-scale research systematically exploring the oral health of both groups will inform the design and delivery of community-based interventions.

Objectives

Dental antibiotic stewardship is crucial in low- and middle-income countries where the burden of antimicrobial resistance (AMR) is high and antibiotic misuse is common. Given that India is the most populous country, the largest antibiotic consumer and has a large dental prescriber population, this study investigated the extent to which current Indian policy and practice for dental antibiotic prescribing and stewardship aligns with the global policy and best practice.

Methods

The READ approach was used to identify and extract data and synthesize the findings. Policy documents on dental antimicrobial stewardship were identified using a systematic search strategy involving nine medical and grey literature databases (Medline, Global Health, Web of Science, Cochrane, CINAHL, Eldis, Global Index Medicus, Proquest and Opengrey), targeted websites (government organizations and dental regulatory bodies) and contact with experts. Framework analysis was used to code extracted data into themes related to dental antimicrobial stewardship.

Results

Of the 3039 records screened, 25 documents were included in the final analysis. The analysis showed a lack of guidelines or toolkits for appropriate antibiotic prescribing in dentistry in India. The treatment guidelines for antimicrobial use in common syndromes published by the Indian Council of Medical Research had no section or content for dental practitioners. Furthermore, the undergraduate dental curriculum developed by the Dental Council of India (DCI), included little content on appropriate antibiotic prescribing and no mention of AMR or stewardship. There were no educational resources either for dental practitioners or patients in the documents.

Conclusion

This document analysis showed that there was little or no mention of dental antibiotic prescribing guidelines in key policy documents such as the National Action Plan on AMR. In addition, contradictory and subjective information provided in some policy documents could encourage dentists and other health professionals such as general practitioners to prescribe antibiotics for common dental conditions for which they are contra-indicated. There is an urgent need to develop relevant guidelines and include these in Indian policy documents on AMR particularly the National Action Plan on AMR.
