Rare case of gemination of mandibular third molar—A case report

Abstract

Fusion and germination are the anomalies that occur due to some developmental eccentricity during the time of morpho-differentiation of the tooth bud and have a close resemblance to each other. The gemination is an attempt of the division of a single tooth into two and, hence, appears as an enlarged single tooth while the tooth count is normal when the affected tooth is counted as one. Its exact pathogenesis is ambiguous. This anomaly has been observed mostly in deciduous dentition as compared to that in permanent dentition. Gemination is rarely associated with the third molar and, hence, the terminology is arguable when this condition is seen in relation to the third molar. In the present article, a case of germination of mandibular third molar has been reported.

Endodoncia y rehabilitación protésica como alternativa terapéutica de geminación dental

“…Se presenta con mayor prevalencia en la dentición decidua (0,5%), aunque también puede presentarse en la dentición permanente (0,1%), en ambos casos los dientes anteriores son los más afectados, los reportes indican que los dientes geminados unilaterales son los más frecuentes que los bilaterales (0,01% dentición primaria y 0,02 % en dentición permanentes) (15,17). El caso clínico presentado corresponde a un diente geminado unilateral correspondiente a un incisivo lateral derecho (1.2) lo cual guarda relación con los datos epidemiológicos presentados.…”

“…que puedan afectar a los dientes adyacentes. Por lo tanto, las posibles opciones de tratamiento pueden ser: extracción, tratamiento de conductos (endodoncia), ortodoncia y rehabilitación estética, siendo necesario un buen diagnóstico (11,14,15). En el presente artículo se reporta un caso de geminación en un incisivo lateral superior derecho, mismo que fue tratado de manera multidisciplinar realizando la endodoncia en primer lugar y posteriormente la prótesis fija unitaria, para lograr los objetivos estéticos y funcionales que el caso requería.…”

A Geminated Mandibular Second Molar—A Case Report

“…Tooth gemination and fusion are anomalies that occur during the morpho-differentiation stage of odontogenesis [7]. The precise aetiology of geminated teeth is uncertain, but studies show a variety of local and systemic factors to be responsible for the developmental disturbances.…”

Endodontic management of a rare case of the geminated maxillary second molar tooth using CBCT

“…In the majority of cases, it is seen in anterior teeth, and it is rarely seen in posterior teeth. 4 Fusion (Figure 1B) is defined as the union of two neighboring tooth buds during their developmental stage due to physical force or pressure. When these follicles unite, the developmental stage determines whether there should be one tooth with one pulp chamber with confluent enamel and dentin or two separate pulp chambers with the union of dentin only.…”

“…If the bifid tooth is counted as one entity in gemination, the total number of teeth in the dental arch is otherwise normal. In the majority of cases, it is seen in anterior teeth, and it is rarely seen in posterior teeth 4 …”
