Clinical and self-reported oral conditions and quality of life in the 1982 Pelotas birth cohort.

AIM: To investigate and compare the effects of clinical and self-perceived oral conditions on oral health-related quality of life (OHRQoL) among young adults.

MATERIALS AND

METHODS

Adults enrolled in the 1982 Pelotas birth cohort were included in this study. OHRQoL was assessed by the Oral Health Impact Profile-14 (OHIP-14) instrument. Clinical parameters such as dental caries, periodontitis, aesthetics, and occlusal characteristics, and tongue coating were collected through clinical evaluation, while dental anxiety and halitosis were self-reported. Direct and indirect effects of clinical and self-perceived oral conditions on OHRQoL were assessed using structural equation modelling.

RESULTS

Five-hundred and thirty-nine individuals participated in this study. Dental caries (β = 0.12) and periodontitis (β = 0.11) were directly and indirectly (via halitosis, β = 0.05 for periodontitis only) associated with greater OHIP-14 scores, while the other clinical conditions did not influence the OHIP-14 scores. Dental anxiety and halitosis were also associated with higher OHIP-14 scores (β = 0.31 and β = 0.27, respectively).

CONCLUSIONS

This study found a positive association between clinically diagnosed and self-reported oral conditions and OHRQoL; however, the self-reported conditions had a higher impact on OHRQoL.
