title: Tooth abrasion in workers exposed to noise in the Montenegrin textile industry.
abstract: A cross-sectional study was performed on 225 textile workers from a wool production company in Montenegro to test the hypothesis of a relationship between exposure to intense industrial noise and tooth abrasion. The group exposed to intense noise (104 dB (A) Leq) consisted of 111 weavers (82 males and 29 females), while the control group (81 dB (A) Leq) consisted of 114 blue-collar workers (32 males and 82 females) in preparation departments. A specialist in dental prosthetics clinically examined all the subjects and additionally analyzed tooth statuses on hard plaster models. Gender, age, socioeconomic status and tooth brushing habits of workers were controlled as confounding factors. Significantly high adjusted odds ratios for tooth abrasion of 3.74 (95% CI = 1.42-7.85; p < 0.01) were found among female workers exposed to intense noise in comparison with the control group. The analysis of the subclass of male workers with severe tooth abrasion (grades III-IV) revealed significantly high adjusted odds ratios for tooth abrasion of 5.48 (95% CI = 1.76-14.50; p < 0.01) among the noise exposed group compared to the control group. This study suggests that extremely high levels of occupational noise might be related to tooth abrasion in exposed textile workers.
