The impact of substance use on oral health: Analyzing the DMFT index among addiction treatment patients in Bojnurd City

Abstract

Background

Substance use presents significant health challenges for users, including oral and dental disorders. This study aimed to investigate the Decayed, Missing, and Filled Teeth (DMFT) index and its associated factors in individuals affected by substance use.

Methods

This cross-sectional study included 223 voluntary participants who attended addiction treatment clinics in Bojnurd City. Following completion of the demographic questionnaire, the participants underwent oral examinations under adequate illumination on a standard chair, and their DMFT index was recorded.

Results

The mean age of the study participants was 50.21 years. A statistically significant positive correlation was observed between age and the DMFT index (P < 0.001). Place of residence had a notable association with DMFT, with urban residents exhibiting lower DMFT scores than others (P < 0.001). Employed participants had lower DMFT scores than homemakers and unemployed participants (P < 0.001). Participants with lower educational levels had higher DMFT index scores (P = 0.001). The type of substance used showed a significant relationship with DMFT (P < 0.001), and the duration of substance use demonstrated a direct and significant correlation with DMFT (P < 0.001).

Conclusion

The results of this study indicate a high DMFT index among individuals who used substances, with missing teeth comprising the majority of the DMFT index.
