Abstract


Purpose: This study aimed to compare bite force and sleep quality in patients with bruxism before and after using a soft mandibular advancement device.
Methods: Eighteen patients with bruxism attending the Occlusion Clinics of the PUCRS Dental School were selected according to the study eligibility criteria, examined according to the RDC/DTM protocol, and treated with a soft mandibular advancement device. Before the treatment and after 30 days the subjects were tested for: maximal bite force with a cross-arch force transducer placed in the first molar region, sleep quality assessed by means of the University of Toronto Sleep Assessment Questionnaire (SAQ), and number of masseter muscle contractions during sleep measured with the adhesive BiteStrip®. Data were analyzed by Student t tests, Wilcoxon tests, and McNemar tests at a significance level of 0.05.
Results: After 30 days using the mandibular advancement device there was a significant decrease in some bruxism parameters, bite force, and total SAQ score (P < 0.05).
Conclusions: The results suggest that the use of a soft mandibular advancement device for one month reduced bite force and bruxism and improved sleep quality in this sample.
Key words: Bite force; bruxism; mandibular advancement device
