Signos y síntomas clínicos predictores de cicatrización apical 12 meses después de microcirugía endodóntica / Apical Healing predicting Clinical Signs and Symptoms 12 Months after Endodontic Microsurgery

Abstract

Purpose: To analyze spontaneous and percussion pain, as predictors of periapical healing, before and 12 months after endodontic microsurgery (ME). Methods: This was an observational prospective study in patients from the postdoctoral clinic in endodontics at the National University of Colombia who underwent ME. The sample consisted of 61 teeth of 54 patients. The size of apical lesions was compared using dental tomography. The healing process was classified as improvement, in-process, and failure, which were associated with the pre- and post-surgery clinical signs and symptoms. Variables were analyzed through periapical index CBCT-PAI categories, axial perimeter, and presence/absence of spontaneous/percussion pain before and after treatment). A polytomous regression model was developed to analyze data. Results: The absence of intraexaminer variability was determined though F-test (p>0.05). 70.49 % of teeth were classified as "improvement" (successful), 13.11 % as in process, and 16.39 % as failure. Healing was higher among people younger than 45 years of age and females (99 % confidence). Association between percussion pain and post-surgical time was significant (p = 0.002) to classify teeth as failure and improvement. Conclusions: The presence or absence of post-surgical pain is likely indicative of healing allowing classifying teeth as success or failure. The in process category did not show association with percussion pain; however, it could predict the result of ME. (English) [ABSTRACT FROM AUTHOR]
