Background: In addition to behavioral and biochemical abnormalities, a parafunction associated with temporomandibular joint disorders (TMD) resulted in stress-induced depression rats. By exploring how chronic stress influences molar-wear rodents, providing insights into the understanding of depression, TMD, oral health. This study aimed conduct three-dimensional (3D) analysis first molar wear an animal model by comparing attrition cusp variation between stressed male rats control groups. Methods: After validated rats, we obtained 3D scans lower molars analyze patterns. The was applied quantify cusps volume difference morphological structure. data were then compared identify significant differences groups side-by-side. Results: revealed reduction Rats exposed exhibited significantly greater occlusal table than their counterparts (p < 0.05). Conclusions: As dentistry moves towards digital imaging, impact psychological factors on TMD becomes increasingly necessary. demonstrates that can lead tooth wear, suggesting occurrence bruxism, leading cause parafunction.
