Abstract

Inferior third molar impaction remains an actual topic of discussion in modern dentistry due to the frequent complications and treatment contraindications. According to Rock and Elsey inferior third mandibular molar impaction occurs in 73% of young people. Many theories of impaction of inferior 3rd molar have been proposed, but the most popular is the insufficient development of retromolar space. Some authors claim that M3 extraction should only be performed when complications may occur, others say that M3 should be extracted if there are no contraindications, but Martin Kunkel is the advocate of the prophylactic extraction of the inferior third molar. In order to achieve the proposed goal, the frequency of impaction of mandibular third molar and their relationship with neighboring anatomical structures was evaluated. There were statistically processed data of medical records and radiographic examination. This study was made based on 320 patients treated in the University Dental Clinic nr.2, SUMPh ,,Nicolae Testemițanu”. Of these, 147 patients were selected: 58 patients with impacted inferior 3rd molar and 89 patients with inferior 3rd molar apparently erupted in the correct position. The most common complication caused by M3 was pericoronitis, followed by second molar caries.

Highlights

Teeth that are completely or partially within the bone and soft tissue for various reasons, despite passing the normal eruption age, are calledCURRENT ISSUES AND PROSPECTS FOR THE DEVELOPMENT OF SCIENTIFIC RESEARCH impacted teeth
The study group comprises 263 ambulatory medical records of the patients who addressed between 01.10.19 and 01.03.21 in the University Dental Clinic no. 2 during the period 2017-2018 with the impaction of the inferior third molar
The factor was the occlusal space available for M3 eruption, and after analyzing the patients’ radiographic images, we found out that the most common position is Level B, where the occlusal plane of the impacted tooth is between the occlusal plane & the cervical margin of the 2nd molar

Summary

Introduction

Teeth that are completely or partially within the bone and soft tissue for various reasons, despite passing the normal eruption age, are called. CURRENT ISSUES AND PROSPECTS FOR THE DEVELOPMENT OF SCIENTIFIC RESEARCH impacted teeth. Impacted teeth may cause various pathologies, such as pericoronitis, infection, unrestorable caries, root resorption in adjacent teeth, periodontal bone loss, cystic lesions, and neoplasms. The impacted position can be horizontal, vertical, mesioangular, or distoangular. The teeth with the highest impaction rate are mandibular third molars. The aim of this study is to predict the difficulty of the extraction based on different indices, so that we could establish the attitude and tactics of surgical treatment of inferior molar impaction
