Abstract: This cross-sectional study aimed to clarify patients' characteristics with bruxism at the College of Dental Medicine, Rangsit University. Data from 250 patients' occlusion chart records were reviewed. Bruxism was more prevalent in females (108 patients; 59%) than males (75 patients; 41%), with no age difference between bruxism and non-bruxism. Having a sleep well at night (p = 0.037), clenching, or grinding awareness (p < 0.001), open mouth problems (p = 0.006), and jaw joint problems (p < 0.001) had a significant association with bruxism and non-bruxism patients. Regarding the jaw movement of dental patients, it was shown that patterns of mandibular movement (p = 0.002) and pain during mandibular movement (p < 0.001) had a significant association with bruxism and non-bruxism patients. Patients with deviation or deflection mandibular movement had a 61% decreased risk of bruxism (OR = 0.392, 95%CI = 0.212,0.725). Patients with no pain during mandibular movement had a 9.4 times higher risk of bruxism (OR = 9.381, 95%CI = 3.830, 22.981). Midline shift (p = 0.024) and interference (p = 0.035) were significantly associated with bruxism and non-bruxism, respectively. Patients with no midline shift had 2.3 times (OR = 2.29, 95%CI = 1.120,4.720) higher risk of having bruxism, and patients with no interference had 2.5 times (OR = 2.541, 95%CI = 1.117, 5.780) higher risk to have bruxism. Dental patients with bruxism had a significantly wider range of mouth opening than non-bruxism patients (p = 0.023). The range of mouth opening in bruxism patients ranged between 23 and 60 millimeters, with a median range of 42 (37, 46 millimeters), while the range of mouth opening in non-bruxism patients ranged between 19 and 52 millimeters, with a median range of 40 (35, 45 millimeters). According to oral status, bruxism patients had a higher chance of experiencing tooth wear compared to non-bruxism patients. When all the bruxism-related factors were entered into multivariate analysis, having a history of clenching or grinding awareness (OR = 5.04, 95%CI = 2.39, 10.66; p < 0.001) and a history of mandibular movement problems (OR = 2.28, 95%CI = 1.17, 4.43; p = 0.016) were associated with bruxism without the influence of age, sex or other related factors.
