Dental Caries Experience and Utilization of Oral Health Services Among Tibetan Refugee-Background Children in Paonta Sahib, Himachal Pradesh, India

Oral health status of 916 children in Tibetan settlement (Bylakuppe, India): A cross-sectional descriptive study

BACKGROUND

Dietary and oral hygiene habits among integrated migrant cultural minorities can vary and could impact susceptibility to caries.

AIM

This study aimed to assess and compare the oral health status of Tibetan schoolchildren living in the Tibetan settlement of Bylakuppe, India, stratified by type of residence.

DESIGN

A descriptive cross-sectional study was conducted among Tibetan schoolchildren attending nine schools in the Bylakuppe region.

RESULTS

The study population consisted of 916 children aged 5-17: 702 (76.6%) living in secular houses (LSH) and 214 (23.4%) living in monasteries (LM). The prevalence of dental caries was 70.9%, and the mean value of decayed, missing, filled teeth for mixed and primary dentition (DMFT*; dmft) of LSH children (1.56 ± 2.34/1.74 ± 2.66) was higher than of LM ones (1.14 ± 2.34/0.83 ± 2.80; p < .001). DMFT for LM children (1.46 ± 2.04) was slightly higher than for LSH children (1.38 ± 1.96; p > .05). Among the sample, 99.1% had a good simplified Oral Hygiene Index (OHI) and LM children showed higher rates of good values (99.5% vs. 98.2% in LSH children). Most children needed preventive/routine dental treatment, whereas 16.6% needed urgent dental treatment. In 4.5% of children, oral mucosal lesions were present.

CONCLUSION

This study confirms the high need for dental treatment in the children of the Tibetan settlement investigated.

Factors associated with access to dental care among refugees: A systematic review of quantitative studies

OBJECTIVES

To identify, appraise and synthesize the published evidence from quantitative studies on the individual and contextual-level factors determining access to dental care among refugees worldwide.

METHODS

A systematic literature search was conducted until the last week of February 2022 in four electronic databases - MEDLINE, Embase, Web of Science (all databases) and APA PsycINFO - without any restrictions. Quantitative studies published in English language and meeting the a priori eligibility criteria were reviewed and data extracted. Quality assessment was conducted using the National Institutes of Health tool. The identified factors were stratified according to the framework of the Behavioural Model of Health Services Use, and the evidence related to each of these factors was summarized in tables. Narrative synthesis of the findings was conducted.

RESULTS

The search retrieved 6776 unique records, of which 69 were deemed eligible for full-text screening and nine studies were included in the final data analysis and synthesis. The studies were rated to be of 'fair' quality at best. Self-reported previous dental visits was the most commonly used measure of access. Associations between individual-level factors and dental care access were most frequently examined (predisposing [n = 6], need [n = 2] and enabling [n = 1]), while the contextual-level factors were rarely examined (predisposing and enabling [n = 1, each]).

CONCLUSIONS

Individual-level predisposing factors, such as English language proficiency, education, health and dental literacy and acculturation and integration, were shown to be significantly associated with refugees' access. There is limited evidence to determine the effect of individual enabling and need and contextual factors.

Higher prevalence of dental caries and periodontal problems among refugees: A scoping review

Background

We assessed the prevalence data on oral health diseases, namely dental caries and periodontitis, among refugees and asylum seekers worldwide.

Methods

A systematic search of Scopus, Embase, and PubMed retrieved 1225 records; following title and abstract screening, 58 studies remained for full-text eligibility screening based on pre-defined inclusion criteria. Twenty-six studies were included in the review.

Results

Dental caries and tooth loss due to caries were high in refugee populations, regardless of their age, gender, or nationality. The adult population had a mean decayed, missing, and filled teeth (DMFT) index score of 9.2 (standard deviation (SD) = 2.3); children had a score of 3.1 (SD = 1.1) for deciduous teeth and 2.5 (SD = 1.1) for permanents. Caries prevalence among refugees ranged from 4.6% to 98.7%, and gingivitis from 5.7% to 100%, indicating a high heterogeneity in their oral health. Regarding oral health accessibility, 17% to 72% of refugees had never been to a dentist, showing a very low level of accessibility to dental health services.

Conclusions

Interventions and policies need to be designed to reduce oral health inequalities among refugee populations and asylum seekers, and host countries must implement strategies to increase their access to oral health care. Existing data should be used to set priorities for improving the oral health of refugees.

Utilization of dental care services among adult Indian population: A meta-analysis of evidence from 2011-2022

Background: This study aimed to generate a pooled national estimate on dental health care services utilization by the adult population in India from any public or private facility in an effort to highlight the demand and usage for oral health care. Methods: In this meta-analysis, PubMed, ScienceDirect, DOAJ, and Google Scholar were searched using a search strategy that combined MeSH headings and keywords (e.g., "Oral Health", "Dental Health Services", utilization, India, etc.) for articles on dental utilization among Indian adults, published between January 2011 and June 2022. Study quality was assessed using the NIH Quality assessment tool, and a random-effects inverse-variance method was used for pulling utilization proportions. Meta-regression and sub-group analyses were conducted to identify the sources of heterogeneity. Heterogeneity is reported as I². To examine publication bias, the funnel plot, egger's test, and trim-and-fill analysis were performed. Results: From 4012 identified articles, 21 were eligible for inclusion. The pooled dental care utilization amongst Indian adults were found to be 23.96% (confidence interval [CI]: 16.81%- 31.11%, P<0.001, I²=98.93%), and the highest estimate was in South Zone (30.02%, CI: 19.14-40.90, P<0.01, I²=98.63%). Visual inspection of the funnel plot revealed the presence of publication bias (egger's P value 0.02). A mild decrease in utilization estimate was noted through trim and fill analysis (adjusted estimate 17.65%, CI: 8.97-26.33, P=0.03). No significant subgroup effect was found for the variables study zone and conduction years (P value: 0.09 & 0.34 respectively). Conclusion: Future studies should be undertaken to focus on the demand and supply of oral health care services since an evidential gap has been identified due to the uneven distribution of studies available from various regions of India. The heterogeneity can be attributed to the diverse socioeconomic, literacy, and inherent health system performance status.

Are parents' education levels associated with either their oral health knowledge or their children's oral health behaviors? A survey of 8446 families in Wuhan

Background

Children aged 6–7 years are in the early mixed dentition, which is a period of high prevalence of dental caries and other dental diseases and a critical period for the formation of oral health behaviors. Therefore, good oral hygiene habits of children and oral health knowledge of parents are very important. This study sought to explore the relationship between children’s oral health behaviors, parental oral health knowledge, parental choices of pit and fissure sealants, and parents’ education levels based on a large-scale sample size for the first time, and to compare the influences of parental education levels between parents.

Methods

Families of the first and second graders of primary schools in Wuhan Hongshan District were included in this study. A total of 8446 questionnaires were collected to obtain comprehensive information on children’s oral health behaviors, parents’ oral health knowledge and parents’ pit and fissure sealants-related choices. The relationship between these outcome variables and parents’ education levels were studied using logistic regression analysis and chi-square test.

Results

Parents who reported good educational background had more favorable oral health knowledge than those of other parents, and their children had better oral hygiene behaviors. Four indicators of five measures to children’s oral health behaviors were significantly associated with mother’s education level (P < 0.05), and three of them were related to father’s education level (P ≤ 0.01). Moreover, seven indicators of eight measures to parents’ oral health knowledge were significantly related to mother’s education level (P < 0.05) and four of them were affected by the father’s (P < 0.05). In addition, parents with higher educational attainments paid more attention to the completeness of medical facilities, the environment of dental practice, the distance to treatment sites, and took less concern of children’s willingness when choosing the pit and fissure sealants sites.

Conclusions

In families with children at the early mixed dentition stage, parents with higher education levels tend to have better oral health knowledge and more oral health care needs, such as pit and fissure sealants. In addition, children of parents who have better educated parents tend to perform better oral hygiene practices.
