Does Emotional State Improve Following Temporomandibular Joint Total

Background: Temporomandibular joint total joint replacement (TMJTJR) offers patients the opportunity for improved function and reduced pain. TMJTJR also has the potential to affect a patient's emotions in a positive or negative manner.Purpose: The purpose of this study was to evaluate changes in emotional state for subjects undergoing TMJTJR.Study Design, Setting, Sample: The authors implemented a retrospective cohort study.Subjects who received TMJTJR were identified from the TMJ Inter Network, which is a study group comprising more than 130 temporomandibular joint surgeons. Subjects between the ages of 18 and 65 years with complete medical records and pre/post TMJTJR video/audio recordings were enrolled in the study. Predictor variable: The predictor variable was time (preoperative and postoperative). Main outcome variables: The primary outcome variable is change in the emotional state. All subjects had preoperative (T0) recorded interview as well as a postoperative (T1) interview at 3 to 6 months. The eight-category emotional state was classified as neutral, happy, sad, angry, fearful, disgusted, surprised, and bored. The three-category emotional state was classified as neutral, positive, and negative. The emotional state was measured using artificial intelligence at T0 and T1. The secondary outcome variable was pain score and maximal interincisal opening. Covariates: The covariates are gender, age, diagnosis, prosthetic side, TMJTJR design, and TMJTJR type. Analyses: The relationship between emotional state change and covariates was examined using both the c2 test and the Kruskal-Wallis H test. The significance of the change in categorical data after surgery was examined using the McNemar-Bowker test. P values < .05 were considered statistically significant.Results: Thirty-three subjects were included in the study. The mean age was 30.09 +/- 8.69 with 15 males (45%) and 18 females (55%). The percentage of subjects with preoperative neutral, happy, sad, angry, and fearful emotional states was 24, 15, 24, 9, and 27%, respectively. The percentage of subjects with postop-erative neutral, happy, sad, angry, and fearful emotional states was 21, 39, 21, 12, and 6%, respectively. The change in emotional state was statistically significant (P = .037). There was no statistically significant relationship between covariates and emotional state changes (P > .05).Conclusion: According to the assessment of artificial intelligence, TMJTJR improves the emotional state of patients.(c) 2023 American Association of Oral and Maxillofacial Surgeons J Oral Maxillofac Surg 81
