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.

A qualitative study on the oral health of humanitarian migrants in Canada.

OBJECTIVES: There is limited evidence to guide oral health policy and services for the 25,000 refugees and asylum seekers who arrive in Canada yearly. The purpose of this study was to explore and understand the pre-migration use of dental services, oral health knowledge, and the effects of oral disease among newly arrived humanitarian migrants in order to inform policy and practice for the population. METHODS: Using focused ethnography and the public health model of the dental care process, we conducted face-to-face interviews (50-60 minutes) with a purposive sample of humanitarian migrants who had indicated the need for dental care. We observed mobile dental clinics that provided care to underserved communities in Montreal. Data were analyzed using a thematic and contextual approach that combined inductive and deductive frameworks. RESULTS: Participants included 25 humanitarian migrants from four global geographical regions. Five major thematic categories were explored: problem-based dental consultation, self-assessed oral health status, causes of oral diseases, personal oral hygiene, and good oral health for wellbeing. In their countries of origin, participants consulted a dentist when oral symptoms persisted. They cited excessive sugar consumption and inadequate oral hygiene as causes of oral diseases, and reported significant oral diseases impacts that limited their daily functions and wellbeing once in Canada. CONCLUSIONS: Humanitarian migrants were knowledgeable about causes of oral disease and the importance of good oral health, yet poor oral health continued to affect their lives in Canada in important ways.
