MAXIMUM BITE FORCE AT FIRST MOLARS IN ADULTS WITH SLEEP BRUXISM
Main Article Content
Abstract
Objective: To compare maximum bite force (MBF) at first molars between adults with and without sleep bruxism (SB). Methods: Cross-sectional study of 20 adults (10 SB, 10 non-SB), aged 18–45, Angle Class I, 28 teeth (not counting third molars). SB was diagnosed by the AASM (2013) criteria. MBF measured at first molars with the BFM F4 device. GraphPad Prism v10.0 was used for statistical analysis. Results: SB group: males 632.8 ± 95.2 N; females 553.4 ± 83.7 N. Non-SB groups: males 614.5 ± 91.0 N; females 536.1 ± 80.5 N. Differences between the SB and non-SB groups were not statistically significant (p > 0.05). Males consistently exhibited higher MBF than females (p < 0.05). Conclusions: Adults with SB tended to exhibit higher MBF at first molars, particularly males; however, these differences were not statistically significant. Gender has a strong influence on MBF, while SB may play a secondary role.
