Abstract

Objectives: A cross – sectional study was to obtain an overview of tooth wear and common associated factors among young dental students aged 18 to 25. Methods: The severity of tooth wear was evaluated according to the Tooth Wear Index described previously by Smith and Knight in 1984. The occlusion was evaluated separately by two other examiners. Results: The prevalence of tooth wear was 98,1%. The prevalence of cervical wear was 68,6%, occlusal/incisal wear was 98,1%, buccal wear was 23,3%, lingual wear was 32,9%. Average tooth wear score was 0,29 ± 0,09. Age, gingival recession and the cuspid high slope were found to be closely associated with cervical wear lesions. Bruxism, deep bite, the cuspid low and average slope were a predisposing factor for occlusal wear whereas open bite was a protecting factor against wear of the incisal. The age factor increases significantly with increasing degree of the buccal wear. Conclusions: Age, gingival recession, occlusal condition were found to be closely associated with cervical wear lesions.
