Abstract
Objective
This study aimed to prospectively observe gustatory and neurosensory alterations following surgical removal of mandibular third molars.
Material and methods
A prospective clinical study was conducted with patients who required mandibular third molar extraction, recruited from the Division of Oral and Maxillofacial Surgery at the Federal University of Ceará (Brazil). Age, sex, and radiographic signs were recorded. The outcome variables were the presence or absence of gustatory and neurosensory alterations. The patients were observed preoperatively and at 7, 30, 90, and 180 days postoperatively by using gustatory and neurosensory tests.
Results
The response to sweet (p = 0.509) and sour (p = 0.078) stimulus did not alter significantly over time. The salty threshold significantly increased from the preoperative to 7- and 30-day postoperative periods, returning to baseline values at 90 days postoperatively (p = 0.038). The bitter threshold increased significantly from the preoperative to 7-day postoperative period, returning to baseline values at 30 days after surgery (p < 0.001). Regarding neurosensory evaluation, there was an altered response to stimulus at 7 days postoperatively in specific studied areas, returning to baseline values 30 days after surgery (p < 0.05).
Conclusion
The present study shows that mandibular third molar removal was associated with slight sensory disturbances related to mechanical, tactile, and gustatory perception. Regarding the recovery period, all patients returned to normal function without intervention, over a period ranging from 30 to 90 days.
Clinical relevance
This study highlighted the importance of a sensory evaluation following removal of third molars, notably regarding mechanical perception and gustatory threshold assessment.
