Factores que influyen en el tiempo quirúrgico en exodoncias de terceros molares en clínica UCSG A-­2017.

Abstract

Introduction: The third molar extraction is a surgical procedure that is increasing its incidence in the city of Guayaquil. Despite being an outpatient surgery there are factors that interfere with the surgical time during the procedure. Among them: the position, angulation, radicular form, and the surgical technique. Objective: To determine which factors influence the surgical time in third molar extractions performed by students in the UCSG A-2017clinic . Materials and methods: The cross-sectional descriptive study was performed in 150 patients treated at the UCSG clinic. The patients were randomly selected per the inclusion and exclusion criteria. The factors influencing surgical time of third molar extractions were determined clinically, radiographically, and also with a stopwatch. Results: 150 samples were analyzed of which, 43% of these were performed on upper third molars and 57% on lower third molars. Results indicated that a vast majority of lower third molars had an IA position according to Pell and Gregory. Out of these 46% were vertical. 57% of upper third molars were vertical and 40% lower third molars were mesioangular according to Winter's classification. 54% of students performed extractions using the elevator / forceps technique. They performed the extractions in a range of 1-10 minutes, average time being 5.88 minutes. Conclusion: Females had the highest percentage of extractions. Vertical angulation was most present in upper third molars and the IA position in the lower third molars. The forceps elevator technique results in a favorable surgical of 1 to 10 minutes. I can safely conclude that the surgical time variable has a significant relationship with morphometry and surgical technique; while with other variables don´t.
