Accuracy of the Brux Checker Oral Device for Sleep Bruxism Diagnosis Accuracy of the Brux Checker Oral Device for Sleep Bruxism Diagnosis
Objectives: Sleep bruxism (SB) subjects to serious consequences. Simple and accurate methods for diagnosis of SB are needed to prevent these serious consequences. The aim is to develop and test accuracy of an oral device for diagnosis of SB.
Methods: 24 participants were recruited following clinical diagnostic criteria of International-Classification-of-Sleep-Disorders-2005 to SB group(n=12) and nonSB group(n=12). The Brux Checker is a custom-made oral device made from 0.1 mm.-colour-thermoplastic sheet molding from upper-dental-stone-model of an individual. Both groups wore for 14 consecutive nights during sleep. Outcome of abraded and perforated area are collected after wearing for 1 night, 7 nights, 14 nights using standardized photography and computerized analysis. Perforation of Brux Checker was a positive sign for SB. Chi-square was used for demographic data. Either Unpaired t-test or Mann-Whitney U test was used depend on normality of data. Discrimination diagnosis was assessed. P≤0.05 was significant.
Results: The mean age of SB and nonSB group was 28.1±10.6 and 21.5±1.8 year old. Sum of abraded and perforated areas of SB were greater than nonSB group significantly in 1st,7th,14th night and increase significantly from 1st,7th,14th night within each groups. The positive likelihood ratio with 95% C.I. in the 1st,7th,14th was 1.94(0.45-8.94),1.38(0.61-3.19),2.19(1.10-4.39) respectively. The negative likelihood ratio in the 1st,7th,14th was 0.81(0.50-1.28),0.72(0.31-1.63),0.14(0.47-0.99) respectively. The median score of satisfaction on comfortable, easily wear, sleep interfere were 6(3-10), 5.5(0-9), and 4(0-8). The Brux Checker preference was 70.80%.
Conclusions: The Brux Checker oral device was an economical device and sensitive to detect SB by wearing for 14 nights. The discrimination diagnostic values were good for screening SB. Patients’ acceptance was good. There are no side effect from this device.
