Third molar Dysimpaction surgery is a common procedure in the dental clinic and there are factors such as location, surgical difficulty, and impaction that can increase the risk of Temporomandibular Disorders (TMD). The objective of this research was to evaluate thermotherapy and cryotherapy as a conservative treatment to prevent symptoms of temporomandibular disorder after third molar Dysimpaction surgery. This is an experimental longitudinal study with a quantitative approach. The study included 60 people, aged between 18 and 35 years, who reported to the Focus Centre for Teaching and Research, located in Teresina, Piauí. Individuals with any acute or chronic condition that limited their ability to participate in the study, individuals with a history of maxillofacial trauma, participants who did not complete all stages of the research, and individuals whose surgery time exceeded 30 minutes were excluded. Each patient underwent surgery to remove the third molar. Participants were randomized into two groups: G1 (experimental group): individuals undergoing conservative treatment for TMD intervention, such as cryotherapy and thermotherapy, and G2 (control group) without the intervention of conservative treatment after surgery. Both groups responded to the DC/TMD, pain diary and use report and postoperative medication count and mouth opening was measured with the aid of a millimeter ruler. There was a significant difference between the groups, showing lower pain intensities in the group treated with thermotherapy and cryotherapy (P<0.0001), a significant difference was also detected between the average mouth opening of the observations performed (P<0.0001). It was found that no participant in the treated group reported severe pain, while in the untreated group, there was no report of the absence of pain.
