ABSTRACT
Objective: The objective of this study is to compare mean periodontal pocket/probing depth with Envelop flap and modified triangular flap in patients undergoing impacted 3rd molar surgery.
Study Design: A comparative study
Place and Duration of Study: This study was conducted at the Oral and Maxillofacial Department of Multan Dental College/ Ibn-e-Siena Hospital Multan from 13th Sept 2022 to 12 Dec 2022.
Materials and Methods: Non-probability sampling technique with sample size of 150 cases; with 75 cases in each group is calculated at 95% confidence level, 80% power of test and taking magnitudes of mean postoperative periodontal pocketing probing depth i.e. 5.4+0.5mm in Envelop flap and 4.7+0.5mm in Modified triangular flap group in patients underwent impacted third molar extraction.
Results: The mean postoperative periodontal pocket depth in modified triangular flap (group A) was4.51±0.9mm and5.68±0.6mm in envelop flap (group B) groups in patients underwent third molar extraction with P= < 0.0001.
Conclusion: There is a higher incidence of periodontal pocket formation when envelop flap retraction is done. Thus, envelop flap should not be retracted while surgical extraction of mandibular third molar.
