摘要

Objective To study the accuracy of BruxChecker in assessing sleep bruxism.

Methods In total, 35 subjects were categorised into two groups: 16 subjects with sleep bruxism (SB) and 19 with no sleep bruxism (NSB). Each participant wore a BruxChecker for 14 consecutive nights. Wear patterns were evaluated on nights one, seven and fourteen, focusing on abrasion (wear without perforation) and perforation areas. Clinical assessment was the reference standard, with BruxChecker perforation indicating a positive result for SB.

Results The mean age was 28.0 ± 9.3 years (SB) and 21.6 ± 1.7 years (NSB). The SB group exhibited significantly larger abraded areas on the BruxChecker compared to the NSB group on all three nights. Additionally, the SB group had significantly greater perforation on the fourteenth night. The diagnostic performance of the BruxChecker varied over time. On the first night, sensitivity and specificity were 31% and 84%, respectively. By the seventh night, these values were 63% and 42%, respectively. On the fourteenth night, sensitivity increased to 94%, with specificity decreased to 32%.

Conclusions BruxChecker may offer a practical and relatively cost-effective tool for assessing sleep bruxism in individuals with probable sleep bruxism. Its diagnostic performance appeared to improve when used over 14 consecutive nights, though its accuracy remains limited compared to standard methods.
