ВАРІАБЕЛЬНІСТЬ РОЗМІЩЕННЯ ТРЕТІХ МОЛЯРІВ У НИЖНІЙ ЩЕЛЕПІ

Abstract

Introduction. Wisdom teeth are the most mysterious part of human anatomy because there are still no clear terms when these molars erupt. There are several basic classifications that are based on the following: the angle of inclination and the position of the tooth germ in the bone; the eruption state; location of roots. With the help of screening, which includes a clinical examination and the review of panoramic X-rays, tooth location in the jaw is identified. Today, the removal of third molars without significant reason is very common. There is a debate among foreign doctors about the necessity of these teeth for a person. Objective. To find out the frequency of eruption, the absence of a dental germ and possible locations for rudiments of the third large angular teeth in the lower jaw of a modern person with a physiologically formed dental bite. Research methods. Four hundred individuals from the Western region of Ukraine were screened using Panorax to establish various locations of the mandibular third molars. These panoramic X-rays were classified by age, gender, the presence of third molars and the corresponding side of their location. Results. The sum of teeth is calculated based on the total number of erupted, impacted or missing teeth (separately) on one side in all categories. The percentage ratio of the sum of teeth in a certain group on one side to the total number of teeth on the given side was determined. The percentage ratio of teeth of a certain group on one side for a given age group to the total number of teeth for the same group was determined. Conclusion. It has been calculated that patients with erupted teeth constitute 35.29% of all individuals. Moreover, 58.5% of them have both wisdom teeth on the lower jaw. This accounts for only 20.65% of all patients. It was revealed that pathological medial location of the third molar was the most frequent. The lingual positioning of the mandibular third molar was the least frequent.
