“…Mesioangular position characterized by second molar making a convergence angle of >30° (i.e., 40% and 80%) is the most common type of third molar impaction comprising about 43% of all third molar impactions. [12] In the present study, of 150 radiographs, 97 (65%) impacted third molars are in mesioangular in position, of which 60 (69%) impacted third molars causing decay on adjacent second molars followed by 31 (21%) impacted third molars are in horizontal position, of which 20 (23%) impacted third molars cause decay on adjacent second molars.…”

Introduction: Impacted third molars are the most frequently impacted teeth in humans and can predispose the adjacent second molar to an array of detrimental effects such as caries. Aim: The aim of the present study was to determine the prevalence of impacted mandibular third molars and to evaluate the decay on the second molar as an effect of an impacted third molar in three different age groups. Objectives: The present study evaluates (1) prevalence and determines the decay on the second molar as an effect of impacted mandibular third molars in three different age groups and (2) awareness among the patients about mandibular third molar impaction and its treatment. Materials and Methods: The present study was conducted in the Department of Oral and Maxillofacial Surgery, Kamineni Institute of Dental Sciences, Sreepuram, Narketpally, Nalgonda, Telangana. A total of 150 radiographs records have been assessed. Based on the age groups, 150 radiographs have been divided into three groups, namely, Group A: Age: 21-25 years (50 radiographs); Group B: Age: 26-30 years (50 radiographs); and Group C: Age: 31-35 years (50 radiographs). Results: The present study reveals that mesioangular impactions were the most prevalent type of impaction, followed by horizontal, vertical, and distoangular impactions. In age groups 21-25 years and 31-35 years, horizontal third molar impaction shows the highest effect on adjacent second molar. Of 150 patients, 87 (58%) show grossly decayed second molar because of the effect of impacted mandibular third molars and 58 (39%) patients were asymptomatic and unaware of existing condition and pathology of an adjacent second molar. Conclusion: Impacted mandibular third molars are associated with complications that are manifested on the adjacent second molars. In this present study, about 58% show decay on the second molar as an effect of an impacted mandibular third molars and 39% were unaware of the existing condition of second molars, and if untreated, it may lead to the severe destruction of the tooth.

The eruption of the first permanent molars is very important as it provides the harmony of the growth of the face and sufficient occlusion support. A delay in the eruption of this tooth can cause morphological, functional and aesthetic disturbances. These include reduced vertical size of the lower face, extruding the antagonist teeth, malloclusion formation, follicular cyst formation, pericoronal inflammation, and roots resorbtion of the adjacent teeth, as well as functional problems of dentoalveolar area, etc. In this regard, the issue of etiology, pathogenesis, early diagnostics and further treatment of lower first permanent molars retention is very relevant for modern orthodontics. In the literary review, morphological and radiological diagnostic criteria of eruption of first permanent lower molars have been presented. Materials and methods of the research. The article reviews and analyzes literature on the etiology, pathogenesis, early diagnostics of retention of the lower first permanent molars. Results The analysis of the literature pointed to a small number of studies regarding the disrupted eruption of first lower permanent molars. In most cases, they are presented as clinical cases. According to the world literature, the prevalence of delayed eruption of the first molar of the mandible was 0.01% to 0.04%. Data from the world literature indicate that the retention of the lower first molar is a polyfactoral disease. According to the etiological factors authors distinguish general and local. Local factors causing delay in teeth eruption include impaired pathway for teeth eruption, abnormality of the tooth form, hyperplasia, displacement of the rudiment because of the cyst and the tumour, loss of space for eruption, gingival fibrosis, idiopathic conditions. Systemic factors include endocrine disorders such as hypothyroidism, hyperthyroidism, hypoparathyroidism, rickets, craniofacial hypertrophy. In the literary review morphological and radiological diagnostic criteria of eruption disturbance of the first permanent lower molars are presented. Thus, the Korean scientists proposed to determine the depth of the retention, the angle of inclination and the space for their eruption on panoramic radiographs. The review presents the classification of retention types for the first permanent molars of the mandible.

“…Although they are mostly asymptomatic, they are sometimes discovered when a patient presents with pericoronitis or pathologies such as a cystic lesion in an adjacent tooth. Thus, the discovery of an impaction usually occurs during a routine visit, and this leads to a late diagnosis (8)(9)(10). There are insufficient studies about impacted premolar prevalence in the literature.…”

Objective: The aim of this study was to determine the prevalence of impacted premolars and the associated pathology of these teeth in the Anatolian population.Methods: This retrospective cohort study was composed of 10246 panoramic radiographs of patients (6074 females, 4172 males) between 2000 and 2011. We reviewed the panoramic radiographs and clinical data and determined the prevalence of impacted premolars to be associated with sex, age, and number of premolars. We investigated the associated pathology and approach of treatment.Results: A total of 83 patients (43 females, 40 males; mean age 23.42±11.18 years, range 12 to 69) had 101 impacted permanent premolars that were either mesioangular (n=47, 46.54%), vertical (n=32, 31.68%9), distoangular (n=14, 13.86%), horizontal (n=6, 5.94%), and/or buccolingual (n=2, 1.98%). Premolar transmigration was absent. Of these premolars, 7 (6.93%) were associated with cystic lesions. In this study, 61.39% of impacted premolars were extracted; 39 (38.61%) were followed up. Conclusion:The prevalence of impacted premolars in the Anatolian population was determined to be 0.98%. Although premolar impaction is infrequent, early diagnosis is important because most of the cases (93.07%) are asymptomatic.
