Grading of Extraction and Its Relationship with Post-operative Pain and Trismus, along with Proposed Grading for Trismus

Extraction of mandibular third molars are somewhat a matter of interest because of its malpositioning , curved roots, proximity to vital structures due to this the procedure is often associated with post operative complications like pain and trismus. The extraction of third molar was classified in four grads according to the difficulty of the procedure.

The purpose of this paper is to find any significant relationship between grading of extraction and post operative complications like pain and trismus.

A total number of 180 patients need to go for extraction of third molar was included in the study. The variables taken into account were grading of extraction, pain six hour post operatively trismus one day after extraction, and trismus five day after extraction. The four grades of extractions as described by Parent in 1974 were statistically analyzed by computing pearson product moment correlation coefficient with post operative pain and trismus first and fifth day to find any co relation between them.

The grading of extraction was found significantly correlated with post operative pain, trismus one day after and fifth day of surgery.
