MANDIBULAR SECOND MOLAR IMPACTION - LITERATURE REVIEW AND CASE REPORTS

Tooth transposition is a rare developmental disorder in which a normal tooth erupts in an inappropriate position. The change in position occurs between two adjacent teeth within the same quadrant. In this article, two cases of tooth transposition involving mandibular molars are described. Patient 1 presented with bilateral transposition between first and second mandibular molars. In addition, giroversion of the first molars was observed. Patient 2 presented with unilateral transposition between the mandibular left molars. Because this tooth disorder does not affect quality of life, both patients declined to seek dental treatment. Out of the 120 cases of tooth transposition found in the literature, 92,5% occurred in the maxilla and 15% were bilateral, 65,8% percent of these cases involved the canine and first premolar; 26.6% involved the canine and lateral incisor; 2,5% involved the canine and central incisor; and only 0.85% involved the first and second molar. The majority of tooth transposition cases occurred in women (66,6%). In literature, tooth transposition is a poorly-documented condition. Consequently, this report seeks to contribute to the existing information in the literature on this disorder.

Tooth Migration

Tooth eruption involves a complex developmental process of tooth migration from the dental follicular origin to the final occlusion position in the oral cavity via the alveolar process. Disturbance of tooth eruption can occur at any point in a series of eruption stages; however, horizontal impaction of the mandibular first molar and primary retention of the primary mandibular second molar are rarely observed simultaneously. This study describes the treatment for two cases of horizontally impacted first molar with primary retention of primary molar. The primary retention of the primary mandibular second molar was extracted, and orthodontic traction was applied to the horizontally impacted primary mandibular first molar. Subsequently, displacement of the premolar tooth bud was improved and space regaining for eruption was achieved, guiding to normal eruption of the first molar.

Distinct Features

Introduction: A buccal bifurcation cyst (BBC) is an uncommon inflammatory odontogenic cyst associated with the permanent mandibular first or second molar in children. Case reports: These reports present two cases of BBC and describes the clinical and radiographic features leading to the diagnosis and the treatment of this lesion. Two patients complained of mandibular buccal swelling around the permanent first molar. The diagnosis of BBC in both cases was based on the clinical and radiographic features. In both cases, only enucleation was performed without extracting the involved tooth. Results: There were no recurrences during follow up. All teeth remained vital and erupted normally. Conclusion: The most appropriate treatment is usually enucleation of the cyst without extraction of the associated tooth. Therefore, knowledge of the distinct features of BBC is important for diagnosis and appropriate treatment.

A supernumerary tooth is an entity in addition to the normal series of teeth that, although rare, can be fused to a tooth, whether deciduous or permanent. Diagnosis and management in cases involving supernumerary teeth in the anterior region of the maxilla are often challenging. The clinical examination associated with the radiographic examination is decisive for the diagnosis and planning of cases. This article describes a case of unilateral fusion of a supernumerary tooth to a permanent upper lateral incisor, in which clinical and radiographic diagnosis was essential for a conservative approach.
