Socioeconomic factors affecting the demand for dental services: A military population-based study, Iran

Purpose: A better understanding of demand behaviours regarding dental services can help oral health planning for military personnel and their families. The objective of this study was to investigate the socio-economic factors affecting the demand for dental services among the military-sector-affiliated families (MSAFs). Methods: The present study was cross-sectional descriptive-analytical research conducted in Tehran metropolis in 2019. The sample size was 385 heads of MSAFs selected using the multiple-stage method (stratified-clustering). The study questionnaire was designed according to the conceptual research model. Ten experts assessed its face and content validity using CVI and CVR indices. Reliability was measured by Cronbach's alpha coefficient, which was 0.82. Four hundred participants took part in filling on the questionnaire. All analyses performed using SPSS 16 and the logistic regression model. Results: Findings of the present study showed that more than 21% of people required dental services but did not actually demand these services. Although people living in the south of Tehran metropolis felt more in need of dental services (OR: 3.63, P = 0.063), the potential of demand for dental services among them was significantly lower than people living in the centre (OR: 0.25, P = 0.049). Conclusion: There were statistically significant geographical inequalities in the need and demand for dental services among the MSAFs. Measures should be taken to provide active dental screening according to the socio-economic status of military families in Tehran.
