1/10. 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 = 1keywords = extraction (Clic here for more details about this article) |
2/10. 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 = 0.33333333333333keywords = extraction (Clic here for more details about this article) |
3/10. Endodontic and periodontal treatments of a geminated mandibular first premolar.AIM: To describe a rare case of gemination involving a mandibular first premolar. SUMMARY: The complex morphology of geminated teeth renders their endodontic and periodontal management difficult. Root canal and periodontal treatments were performed on a geminated mandibular first premolar with three canals. Clinical examination showed two separated crowns with united roots. Radiographically, two distinct pulp chambers with two joined and a third independent canal were seen. Conventional root canal treatment resulted in complete healing of the apical lesion. However, the occurrence of a vertical fracture led to the extraction of the mesial segment. At the follow-up visit, the distal segment was clinically healthy and continued to satisfy functional demands.- - - - - - - - - - ranking = 0.33333333333333keywords = extraction (Clic here for more details about this article) |
4/10. Endodontic and surgical treatment of a geminated maxillary incisor.AIM: A geminated maxillary incisor required complex multidisciplinary treatment to preserve health and restore aesthetics. This report describes the coordination of coronal division, root extraction, bone grafting, endodontic treatment and orthodontics in achieving treatment goals. It is the intention of this report to show how a difficult case could be managed by properly coordinated multidisciplinary care. SUMMARY: Pulp testing of the geminated central right maxillary incisor gave a normal response. Radiographic investigation indicated a connection of the pulp chambers. Both the mesial and distal root were filled with gutta-percha. The connection between the two root canals was sealed with a flowable dentine-bonded resin. After dividing the crown with a diamond bur, the mesial part of the tooth was removed and the extraction socket was filled with beta-tricalcium phosphate ceramic (Cerasorb). Radiographs taken immediately after surgery and after 6 months showed no periodontal or periapical lesions. No signs of external resorption were identified. The diastema between the central incisors was closed by orthodontic treatment. KEY learning POINTS: Geminated teeth may present aesthetic and functional problems which require multidisciplinary care. Careful clinical and radiographic examination is essential to decide on the fate of the coronal and root halves involved. A proper coordination between endodontic and surgical treatment may result in maintaining one tooth half, even if a midroot connection between the pulp chambers becomes evident. Orthograde endodontic treatment, hemisection and orthodontics may solve the aesthetic problem of a geminated tooth.- - - - - - - - - - ranking = 0.66666666666667keywords = extraction (Clic here for more details about this article) |
5/10. Concrescence: report of a rare case.Concrescence represents an uncommon developmental anomaly in which juxtaposed teeth are united in the cementum but not in the dentin. The incidence of concrescent teeth is reported to be highest in the posterior maxilla. The presence of concrescent teeth may influence surgical procedures as well as periodontal, endodontic and even orthodontic diagnoses and treatment. Therefore, consideration should be given to the possible occurrence, recognition, and implications of this anomaly in diagnosis and treatment planning. The purpose of this article is to report a case of concrescence between an impacted third molar and an erupted second molar that was identified postextraction.- - - - - - - - - - ranking = 0.33333333333333keywords = extraction (Clic here for more details about this article) |
6/10. Preserving pulpal health of a geminated maxillary lateral incisor through multidisciplinary care.AIM: To report the multidisciplinary care of an unaesthetic geminated maxillary lateral incisor tooth, which allowed its preservation in the mouth. SUMMARY: Preoperative examination of an unsightly geminated maxillary lateral incisor (tooth 22) demonstrated two pulp chambers and open apices, with normal pulp sensitivity responses. At surgery, a periodontal mucoperiosteal flap was reflected and the distal part of the geminated tooth was removed. The exposed root canal of the preserved tooth was sealed with mineral trioxide aggregate (MTA). The extraction socket and osseous defect was grafted with decalcified freeze-dried bone allograft (DFDBA) before flap closure. During follow-up, distal caries in tooth 22 and a diastema between tooth 22 and 23 were managed with composite resin restorations. Forty-two months postoperatively, normal thermal and electrical pulp sensitivity tests confirmed pulp health. Convincing apexogenesis and dentinogenesis of the developing root was confirmed by radiographic examination. Acceptable periodontal health including 3-4 mm clinical probing depths was achieved. Optimizing aesthetics and occlusion was accomplished without orthodontic treatment.- - - - - - - - - - ranking = 0.33333333333333keywords = extraction (Clic here for more details about this article) |
7/10. Macrodontia of maxillary central incisors: case reports.Two cases of maxillary anterior macrodontia, resulting from fusion and gemination, were treated orthodontically. Problems of esthetics and overjet were solved in the first patient by sectioning and extraction of a fused mesiodens, and in the second patient by treating toward an Angle Class III buccal occlusion.- - - - - - - - - - ranking = 0.33333333333333keywords = extraction (Clic here for more details about this article) |
8/10. Treatment of an unusual case of fusion.An unusual example of anterior tooth fusion is presented in which the involved tooth had one crown, one talon cusp, two roots, and three root canals. Despite extensive multidisciplinary consultations, treatment failed, resulting in extraction of the tooth.- - - - - - - - - - ranking = 0.33333333333333keywords = extraction (Clic here for more details about this article) |
9/10. Esthetic and functional treatment of a fused permanent tooth: a case report.This report describes a young patient with fusion of a maxillary central incisor to a supernumerary tooth. Treatment involved extraction of the fused tooth and orthodontic movement of the lateral incisor to occupy the position of the extracted tooth. A resin composite laminate veneer was placed on the lateral incisor to simulate the appearance of a central incisor. Five years of follow-up revealed that treatment had successfully restored esthetics and function.- - - - - - - - - - ranking = 0.33333333333333keywords = extraction (Clic here for more details about this article) |
