Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The primary objective of this study was to compare between the lingually based triangular flap with the buccally based triangular flap in the surgical removal of impacted mandibular third molars.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Many flap designs used for impacted third molar surgery do not place the mucoperosteal incision on sound bone, as they involve incisions that are placed on the extraction socket resulting in higher incidence of mucosal dehiscence, followed by secondary wound healing

This study involved 20 patient with bilaterally mesially angulated impacted third molar (class II position B). One side was surgically removed using the lingually based triangular flap and the other side was surgically removed using the bucally based triangular flap

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Lingually based triangular flap

Group Type EXPERIMENTAL

Lingually based triangular flap

Intervention Type PROCEDURE

A lingually based triangular flap was used to remove the impacted third molar. An incision was made adjacent to the distal surface of the mandibular second molar and extended along the sulcus to the distobuccal corner of the mandibular second molar, an oblique vestibular incision was made and extended into the vestibular fornix of the mandible. Aligned with the mesiobuccal cusp of the second molar.

It was continued posterosuperior towards the anterior border of the mandibular ramus An incision will be made from the anterior border of the mandibular ramus to the distal surface of the mandibular second molar.

Buccally based triangular flap

Group Type ACTIVE_COMPARATOR

Buccally based triangular flap

Intervention Type PROCEDURE

The impacted teeth was removed using a buccal based triangular flap. It will be extended along the sulcus to the distobuccal corner of the second molar . The incision was continuous, with a relieving vertical incision, oblique into the mandibular vestibular fornix, aligned with the mesiobuccal cusp of the second molar.
