1/115. Endodontic therapy in a fused mandibular molar. This case report describes the endodontic management of fusion involving a mandibular third molar and a fourth molar (distomolar). ( info) |
2/115. Bilateral fusion of the mandibular primary incisors: report of case. Fusion is a common dental finding. However, bilateral mandibular fusion of the primary incisors is a rare event, occurring with a prevalence of less than 0.02 percent. When all four permanent successors are present, this event becomes rarer still. Once fusion has been diagnosed, careful monitoring is required, since problems with exfoliation can occur, along with caries formation in the groove of the incompletely fused teeth. ( info) |
3/115. Endodontic management of a mandibular third molar fused with a fourth molar. CASE REPORT: Developmental anomalies in permanent molars frequently require surgical intervention. A case of a mandibular third molar fused with a fourth molar which was successfully treated with conservative endodontic therapy is reported. ( info) |
4/115. Eruption disturbances of maxillary permanent central incisors associated with anomalous adjacent permanent lateral incisors. Several causes of eruption disturbances in upper permanent central incisors have been described. This report describes six cases in which the failure of maxillary permanent central incisors to erupt appears to be associated with developmental anomalies in the adjacent permanent lateral incisors. The root formation of the unerupted central incisors was delayed in comparison to the contralateral incisors as was the development of the adjacent lateral incisors. The shapes of the crowns were abnormal and in five cases out of the six described, the primary predecessors of the unerupted incisors were fused. ( info) |
5/115. Bilateral dental fusion of the upper central incisors: a multidisciplinary approach. The multidisciplinary treatment of a case of bilateral dental fusion of the upper central incisors with maxillary constriction, crowding, and palatal inversion of one of the lateral incisors is reported. The rarity with which this anomaly appears, along with its complex characteristics, often make it extremely difficult to treat. It requires the involvement of different specialists to find the most suitable treatment for each individual patient. CLINICAL SIGNIFICANCE: This particular case of bilateral dental fusion required the involvement of orthodontists, periodontists, endodontists, and restorative specialists. For the individual evaluation of these extremely complex cases, the esthetic and functional results to be reached must be assessed compared to treatment times and biologic and economical costs. The long-term prognoses of these complex therapies also must be borne in mind. ( info) |
6/115. Fusion of primary incisors--a report of six cases. Six cases of asymptomatic dental twinning anomalies in the primary dentition are reported in 4205 school children. A clinical and radiographic presentation of the cases of fusion of primary incisor teeth is illustrated. This clinical entity has been found to appear with varied clinical and radiographic appearances. An association of fusion of primary incisors with the number of succedaneous teeth was seen. ( info) |
7/115. Connation of permanent incisors: a report of two cases. Presented here are two uncommon cases of connation of permanent incisors. The term connation is being used in this paper instead of fusion, gemination etc., as it ideally describes the anomaly. Various treatment modalities have also been recommended for such cases.

8/115. A supernumerary tooth fused to the facial surface of a maxillary permanent central incisor: case report. A case of a supernumerary tooth fused to the facial surface of a maxillary permanent central incisor is reported. root canal therapy on the maxillary central incisor was performed due to pulpal communication between the supernumerary tooth and the maxillary central incisor after removing the supernumerary tooth structure. The communication was sealed with mineral trioxide aggregate. The difference between fusion and gemination is discussed. ( info) |
9/115. Maxillary lateral incisor with two root canals: fusion, gemination or dens invaginatus? Endodontic retreatment of a maxillary right lateral incisor with two root canals is described. The diagnosis of fusion, gemination or dens invaginatus could not be made, due to conflicting findings, and to previous root canal treatment that erased the original configuration of the pulp chamber.

10/115. Fusion of the permanent maxillary right incisor to a supernumerary tooth in association with a gemination of permanent maxillary left central incisor: a dental, genetic and dermatoglyphic study. The relationship between fusion of the permanent maxillary right central incisor to a supernumerary tooth in association with gemination of permanent maxillary left central incisor and dermatoglyphics were investigated.
