1/41. 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.- - - - - - - - - - ranking = 1keywords = dental (Clic here for more details about this article) |
2/41. 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.- - - - - - - - - - ranking = 6keywords = dental (Clic here for more details about this article) |
3/41. 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.- - - - - - - - - - ranking = 1keywords = dental (Clic here for more details about this article) |
4/41. 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.- - - - - - - - - - ranking = 4keywords = dental (Clic here for more details about this article) |
5/41. An unusual case of talon cusp on geminated tooth.A rare case of talon cusp on geminated permanent central incisor is described. These developmental anomalies cause clinical problems including unsightly dental appearance, occlusal interference, displacement of the affected tooth, attrition, periodontopathy, irritation of the tongue, loss of space and malocclusion. Clinical and radiographic characteristics of these anomalies and modes of treatment are presented. Recognition of this condition and early diagnosis are important to avoid complications.- - - - - - - - - - ranking = 1keywords = dental (Clic here for more details about this article) |
6/41. Primary triple teeth: histological and CT morphological study of two case reports.The macromorphology and micromorphology of two specimens of primary triple teeth using histological and CT analysis approach is analyzed. A single morphological pattern of triple teeth has been found and described: three nearly separate crowns with three separate pulp chambers, and three joined roots with three connected root canals. The characteristic triple teeth appearance occurred because a labial supernumerary tooth is the junction element between two teeth of normal series: the central incisor on the mesial side and the lateral incisor on the distal side. Primary triple teeth suggest an idiopathic abnormality in the distribution of the dental material originated very soon in the dental development. They can be considered as an early double fusion between three tooth germs, initially separate but in close proximity and developing synchronically.- - - - - - - - - - ranking = 2keywords = dental (Clic here for more details about this article) |
7/41. Dental gemination: report of case.Dental anomalies can be classified in different groups: anomalies of volume, anomalies of number, anomalies of form, anomalies of position and anomalies by union. Of the latter, we distinguish between fusion, alveolus-dental gemination, concrescence, coalescence and anchylosis. Gemination is more frequent in the anterior teeth, although it can also affect the bicuspids and molars, being an anomaly of infrequent union (prevalence 0.5%). We present the case of a young male patient age 19, without medical antecedents of interest, that goes to consultation for repeated inflammatory accidents at level of the inferior left retromolar area. These episodes are caused by a semi-impacted inferior third molar that is fused to a supernumerary fourth molar, sharing its roots, crown, pulp chambers and canals. After the appropriate radiologic study and suitable planning, the semi-impacted third molar was extracted under local anaesthesia and without any other complications during or after the operation.- - - - - - - - - - ranking = 1keywords = dental (Clic here for more details about this article) |
8/41. Regional odontodysplasia (Ghost teeth). A case report.Regional odontodysplasia is a rare development anomaly affecting the teeth with an unknown etiology. This dental abnormality involves the hard tissues of the teeth that are derived from both epithelial (enamel) and mesenchymal (dentine & cementum) components of the tooth forming apparatus. Teeth in a region or quadrant of maxilla or mandible are affected to the extent that they exhibit short roots, wide open apical foramen and large pulp chamber, the thinness and poor mineralisation qualities of th enamel and dentine layers have given rise to a faint radiolucent image, hence the term "Ghost teeth". Both the permanent teeth and the deciduous teeth are affected. Females are more commonly affected than males. There is a maxillary predominance (2.5:1) with a predilection for the anterior teeth. Eruption of the affected teeth is delayed or does not occur. Because of the poor quality of the affected teeth, they cannot be rehabilitated for functional use therefore the treatment of choice is extraction with prosthetic replacement. However, necrosis and facial cellulitis appear to be a complication if these teeth are retained. A unique case of regional odontodysplasia affecting the entire right quadrant of mandible is reported here.- - - - - - - - - - ranking = 1keywords = dental (Clic here for more details about this article) |
9/41. Clinical variants in tooth number and crown form: a report of bilateral double teeth associated with a talon cusp.The aetiological factors related to many dental anomalies are still uncertain. Clinical descriptive terms may be useful in communications. This paper describes a previously unreported case of dental anomaly exhibited as bilateral double teeth associated with a talon cusp. The clinical variants related to crown numbers and forms are also discussed.- - - - - - - - - - ranking = 2keywords = dental (Clic here for more details about this article) |
10/41. Radiographic diagnosis of supernumerary teeth: report of six unusual cases.The purpose of this report was to describe the radiographic findings of 6 uncommon situations of supernumerary teeth in a Brazilian pediatric dentistry and orthodontic clinic. Six cases of supernumerary teeth were diagnosed in association with other dental anomalies such as number, position, and form. The supernumeraries were asymptomatic and were detected through routine radiographic examination. The importance of routine radiographic examination is emphasized for the correct diagnosis of supernumerary teeth, and avoidance of associated complications.- - - - - - - - - - ranking = 1keywords = dental (Clic here for more details about this article) |
