Non-biological and Biological Risk Indicators for Tooth Wear Outcomes in Adults.

This study was undertaken to estimate prevalence and severity of tooth wear (TW), as well as to assess non-biological and biological risk indicators for TW outcomes in adults. A cross-sectional study, adhering to the reporting STROBE guidelines, was conducted and had a convenience sample of adults ≥18 years who had at least one bilateral posterior molar contact. A total of 570 participants, seeking consultation at the University Hospital in Brussels, Belgium were allocated to three age groups 18-34 years (n=232), 35-54 years (n=256) and ≥ 55 years old (n=79). Participants answered a self- applied questionnaire regarding socio-demographics, oral hygiene and life style behavior. The questionnaire was tested-retested (ICC=0.71). Inter-examiner reliability for clinical examinations were k=0.76-0.80. The prevalence of TW was 75% (95% CI: 71.7-78.9). Out of these patients, 42% (95% CI: 38. 0-46.3) had as the primary etiological factor the process of dental erosion, while 22% (95% CI: 18.9-25.9) and 11% (95% CI: 8.6-13.9) had the process of dental attrition and dental abrasion, respectively. The severity of TW according to BEWE highest score was mild in 31%, moderate in 28% and severe in 17% of participants. The hierarchical logistic regression model for the association between risk indicators and TW irrespective of the etiology was significant for age (>35-54 yr: OR= 2.35 and ≥55 yr: OR=3.89; pmale: OR=2.03; psensitive teeth: OR=2.34; p=0.005), occlusal splint (>yes: OR=1.62;...
