Introduction. Dental caries is the most common oral health disease of school-aged children around the world. In this study, we aimed to assess the prevalence and associated factors of dental caries in primary schoolchildren in Yasuj township, Iran. Methods. In this cross-sectional study, a total of 460 children aged 7–12 years were investigated. Dental examination was performed at school according to the World Health Organization criteria. Sociodemographic data were collected using a structured questionnaire, and caries statuses of children’s teeth were recorded through a dental chart. Data were analyzed using summary statistics, chi-square test, and logistic regression model with odds ratio. Results. The prevalence of dental caries in primary, permanent, and whole dentition among children was 75.3%, 41.1%, and 89.8%, respectively. Among all considered factors, the caries presence in primary teeth was inversely (p<0.001) and in permanent teeth was positively (p<0.001) associated with the children’s age. Moreover, the odds of decaying permanent teeth were significantly higher in girls, in rural children, and in children whose fathers were not an employee compared to their counterparts (p=0.04, p<0.001, and p=0.02, respectively). Conclusions. The prevalence of dental caries among the studied primary schoolchildren in mixed dentition was high and associated with their sociodemographic factors. Providing and implementing preventive, therapeutic, and informative programs for controlling dental caries at individual, family, and school levels are necessary for local health policymakers.

Objective: Psychological education for families in the form of a model is one of the effective approaches in managing problems caused by mental health problems. The present study aimed to determine the effect of using the participatory care model on the caregiver burden and resilience of home caregivers of patients with mental disorders. Method: In this clinical trial, 66 households with psychiatric patients hospitalized at Shahid Rajaee Psychiatric Hospital in Yasuj during 2014-2015 were selected and assigned into 2 groups of experimental and intervention based on convenience and simple random sampling. The data of this study were gathered by Novak & Guest (1989) Caregiver burden and Sixbey (2005) Resilience Questionnaire before and after intervention. Participatory care model was performed for 12 ninety-minute sessions in the intervention group. No intervention was provided to the control group during the study period. SPSS software (version 21) was used to run the descriptive and inferential statistics. Results: Chi-squared test showed that the caregiver burden was significantly lower in the experimental group than in the control group after the intervention (P = 0.0001). Following the intervention, increased resilience and all its components were observed in the experimental group compared to the control group. According to the independent t test and Mann-Whitney U, the 2 groups were considerably different (P < 0.05). Conclusion: The application of the participatory care model efficiently increased resilience and decreased the intensity of the caregiver burden on the home caregivers of patients suffering from mental disorders.
