Background: Military personnel often face unique challenges in maintaining optimal oral health. This study investigated the oral health status, caries experience, and associated factors among a sample of Iranian soldiers, employing a structural equation modeling (SEM) approach to explore the complex interplay of socioeconomic and behavioral determinants.
Methods: A cross-sectional study was conducted among 658 male soldiers aged 18-30 years from three military barracks in Fars province, Iran. Data were collected through a structured instrument and clinical oral examinations. The study employs the DMFT index, which measures caries experience based on decayed, missing, and filled teeth, along with the Simplified Oral Hygiene Index (OHI-S) to assess overall oral health status. Structural equation modeling was employed to analyze the complex relationships between socioeconomic factors, oral health behaviors, and oral health outcomes.
Results: The mean DMFT score was 3.57 ± 5.91, and the mean OHIS score was 0.56 ± 1.42. SEM analysis revealed that socioeconomic status (SES) indirectly influenced DMFT and oral hygiene scores, mediated by drug use, oral hygiene practices, dietary sugar consumption, and dental visit frequency. Lower toothbrushing frequency was significantly associated with higher DMFT (Estimate = -0.064, p < 0.001) and OHIS scores (Estimate = -0.637, p < 0.001). Drug use (smoking, qalyan, alcohol) was linked to poorer oral health outcomes, while more frequent dental visits were associated with lower DMFT and OHIS scores.
Conclusion: This study reveals the complex interplay between socioeconomic conditions, oral health behaviors, and oral health outcomes among Iranian soldiers. The findings highlight the need for targeted interventions to address modifiable risk factors and improve access to preventive dental care within military settings. Future longitudinal studies are warranted to elucidate further the causal pathways between these factors and oral health outcomes in military populations.
