Coronectomy: A Knowledge, Attitude and Practice Survey (KAP) Among Oral and Maxillofacial Surgeons.

INTRODUCTION

Since mandibular third molars are frequently impacted, third molar extractions are among the most common procedures performed by oral surgeons (35.9-58.7% of all surgical procedures). Inferior alveolar nerve (IAN) injury is major postoperative complication in 0.81-22% of the cases leading to a permanent injury in 1-4% of the cases. Prior studies have proven that coronectomy, a procedure that involves the removal of the crown and coronal one-third of the roots of the third molar with intentional retention of the two-third apical roots to protect the IAN, can thus prove to be a viable alternative in such cases of close proximity to the IAN.

AIM

This study was conducted in India to determine the knowledge, attitudes, and practices of oral and maxillofacial surgeons regarding coronectomy and its role in the prevention of IAN injury.

METHODOLOGY

The questionnaire entitled: "Coronectomy: A Knowledge, Attitude and Practice (KAP) Survey among Oral and Maxillofacial Surgeons" was sent to 120 oral and maxillofacial surgeons. Five questions in each domain, i.e., knowledge, attitude, and practice were designed to know the level of awareness, acceptance, and current status of the performance of coronectomy among oral and maxillofacial surgeons (OMFS). Teeth with acute infection and mobile teeth were excluded from the consideration of coronectomy procedures.

RESULTS

Out of the 120 questionnaires sent, 50 responses were obtained, thus producing a response rate of 41.6%. The male-to-female ratio in the study was 34:16. 52% of the surgeons had performed up to 5 coronectomies during their entire practice, while 16 % had never even attempted the procedure. Only 42% of the respondents preferred coronectomy, but most of the surgeons were in support of practice-oriented continuing.
