Association of Oral Health Indicators with Quality-of-Life Related to Oral Health among Iranian Adolescent.

Background: There has been an increase in the development and use of oral health-related quality-of-life (OHRQoL) measures in the past two decades. This study aimed to assess the association between OHRQoL and clinical oral health measures, among mid-level school children in Southeast of Iran.

Materials And Methods: A cross-sectional study was conducted on a random cluster sample of 11-13 year-old student population. Consented participants interviewed for OHRQoL measurements using Persian version of child-oral impacts on daily performances (OIDP). Oral examination was done by a trained dentist using WHO oral health assessment form, version 2011. Data were analyzed by SPSS software version 20 using Mann-Whitney and correlation tests.

Results: A total of 400 school children participated. The overall mean of decayed missing filled teeth (DMFT) was 1.76 ± 2.4. A total of 82% of the school children presented the impact of oral problems in at least one of the eight daily performances. As DMFT increased, the OIDP score tended to increase or quality-of-life of children tended to be worse (r = 0.397, P < 0.001).

Conclusions: The results showed a positive relation between some oral health status and quality-of-life score.
