Summary
Organic and inorganic factors are effective in the etiology of masseter muscle hypertrophy, which can be unilateral or bilateral. It is known that the habit of clenching and grinding creates hypertrophy due to excessive use in the muscle. In the treatment, intraoral plaque applications, which are not surgical methods, are used as the first option. In the study, it was aimed to evaluate the clinical and ultrasonographic evaluation of the patients who admitted to Ege University Faculty of Dentistry with the complaint of unilateral and bilateral masseter muscle hypertrophy, and to examine the clenching and grinding patterns. The study was carried out on 25 patients (18 females, 7 males, mean age 33.44), 25 healthy individuals (14 females, 11 males, mean age 26) in line with the approval from the ethics committee of Ege University Faculty of Medicine Clinical Research. Wilcoxon analysis was used to analyze nonparametric data (p <0.05). It was determined that the clenching and grinding patterns of the patients with hypertrophy were in the density of the posterior teeth, and they had a Type 2 pattern in the evaluation of muscle ultrasound. Pain reduction was observed after plaque treatment. In ultrasonographic evaluations, it was determined that plaque treatment caused a decrease in the thickness of the masseter muscle, but not any significant change in the fibrillar structure of the muscle. Studies in larger populations are needed to evaluate the success of plaque treatment ultrasonographically.
