1/63. 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.- - - - - - - - - - ranking = 1keywords = tooth (Clic here for more details about this article) |

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 = 0.71428571428571keywords = tooth (Clic here for more details about this article) |
3/63. Unusual presentation of mandibular extraoral sinus in a fourteen year old girl: a case report.A case of fourteen year old healthy girl with complaint of a discharging sinus on the lower right side of face is reported. All teeth were vital and there was no evidence of periodontitis. There was no history of extraction of a tooth. Total leucocyte count, differential leucocyte count, fasting blood sugar, chest x-ray and routine urine examination were within normal limits. actinomycosis and scrofuloderma which simulate such a condition were ruled out by culture study. The intraoral periapical x-ray of mandibular molar showed questionable periapical changes at the time of presentation. But definite osteolysis was observed in the repeat radiograph after three months. It was decided to extract the second molar and curette the sinus tract. The extraction proved to be difficult. On examination of the extracted tooth, it was found that the mandibular second molar and second premolar were fused together. The radiograph of the tooth taken after extraction showed confluence of the premolar pulp with the periodontal membrane. On follow up, the lesion was found to heal satisfactorily.- - - - - - - - - - ranking = 0.42857142857143keywords = tooth (Clic here for more details about this article) |
4/63. 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 = 0.71428571428571keywords = tooth (Clic here for more details about this article) |
5/63. 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 = 0.28571428571429keywords = tooth (Clic here for more details about this article) |
6/63. Bilateral connation of permanent mandibular incisors: a case report.Connated teeth are the consequences of developmental anomalies leading to the eruption of joined elements. According to current definitions, gemination occurs when one tooth bud tries to divide, while fusion occurs if two buds unite. Clinical experience shows, however, that diagnosis can be complicated due to superimposed anomalies. This report describes a unique case of bilateral fusion of permanent mandibular incisors and discusses the differential diagnosis and possible future treatment options anticipated for this particular case.- - - - - - - - - - ranking = 0.14285714285714keywords = tooth (Clic here for more details about this article) |
7/63. 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 = 0.14285714285714keywords = tooth (Clic here for more details about this article) |
8/63. Root-canal treatment of a trifid crown premolar.AIM: To describe successful root-canal treatment of a permanent maxillary first premolar with unusual anatomy. SUMMARY: A diagnosis of irreversible pulpitis of a geminated first premolar was made. Clinical and radiographic examination revealed a tooth with a trifid crown that joined to give the appearance of a single root at the cementoenamel junction. Root-canal treatment involved three separate access openings and treating four canals, three of which joined to exit through a common foramen. KEY learning POINTS: Symptomatic teeth with morphological aberrations can be saved by root-canal treatment.Careful clinical and radiographic evaluation are essential, as treatment must be modified to address the unusual complexities of the root-canal system(s).- - - - - - - - - - ranking = 0.14285714285714keywords = tooth (Clic here for more details about this article) |
9/63. Bilateral fusion of mandibular second molars with supernumerary teeth: case report.Fusion is a developmental anomaly characterized by the union of two adjacent teeth. In this article we report a rare case of bilateral fusion of permanent mandibular second molars with supernumerary teeth. The rarity with which this entity appears, along with its complex characteristics, often make it difficult to treat. The endodontic management of one tooth is described, as well as the successful treatment of a periradicular lesion.- - - - - - - - - - ranking = 0.14285714285714keywords = tooth (Clic here for more details about this article) |
10/63. 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 = 0.57142857142857keywords = tooth (Clic here for more details about this article) |
