Root canal treatment of a root-fractured incisor tooth with internal resorption: a case report.A case is described in which root canal treatment with calcium hydroxide was used successfully to repair a fracture site with internal resorption of the tooth.- - - - - - - - - - ranking = 1keywords = tooth (Clic here for more details about this article) |
2/21. Bur extensor for root canal access.Access to a tooth with a partial canal calcification was made. The access was possible only with a bur extensor connected to a LN bur. Calcification was bypassed, and the canal was completely prepared.- - - - - - - - - - ranking = 0.2keywords = tooth (Clic here for more details about this article) |
3/21. Otodental syndrome: a case report and genetic considerations.A 5-year-old boy presented with otodental syndrome. His maxillary and mandibular incisors were within normal limits. The premolar/molar areas in all quadrants were occupied by markedly macrodontic teeth showing globular shape. The canines had a similar rounded shape. Two canines and 1 of the other abnormal teeth demonstrated areas of yellow hypoplastic enamel. Radiographs revealed that some of the abnormal teeth had bifurcated pulp chambers and pulp stones. Premolar tooth germs were absent. audiometry demonstrated that the child had a marked bilateral sensorineural hearing loss for frequencies above 1000 Hz. No other members of the immediate family were clinically affected. The parents of the child were not aware of any similarly affected relatives. Suggestions with respect to possible genetic mechanisms and gene participation in the etiology of this syndrome are offered.- - - - - - - - - - ranking = 0.2keywords = tooth (Clic here for more details about this article) |
4/21. Obliteration of pulp canal space after concussion and subluxation: endodontic considerations.Concussion and subluxation injuries to permanent teeth lead to obliteration of the pulp canal space in 3% to 11% of cases, depending on the severity of the injury and the developmental stage of the tooth. Obliteration of the pulp canal space may make root canal treatment necessary because of the development of apical periodontitis or for cosmetic reasons. If carefully executed, root canal treatment in teeth with an obliterated pulp canal space is highly successful and may act as a basis for internal bleaching.- - - - - - - - - - ranking = 0.2keywords = tooth (Clic here for more details about this article) |
5/21. Unusual manifestations in X-linked amelogenesis imperfecta.This paper describes a female with X-linked amelogenesis imperfecta (XAI). This case is unusual in having taurodontism, pulpal calcifications, coronal defects prior to tooth eruption and unerupted teeth. These findings have been reported in some cases of autosomal dominant and autosomal recessive AI but have not previously been documented in XAI.- - - - - - - - - - ranking = 0.2keywords = tooth (Clic here for more details about this article) |
6/21. Odontomas--report of 3 cases.Three clinical cases of odontoma were detected in 2 children and 1 adolescent. The tumors were surgically removed. Clinical suspicion was based on facial deformity in one of the cases and on the absence of permanent tooth eruption in the other two. Radiographic evidence of odontoma was confirmed through histological study.- - - - - - - - - - ranking = 0.2keywords = tooth (Clic here for more details about this article) |

8/21. Combined endodontic and surgical treatment of a three-rooted maxillary first premolar.A case is reported in which endodontic treatment of a maxillary first premolar was complicated by the fact that the tooth had three roots. One of the roots was completely calcified and therefore could not be negotiated with endodontic files. There was a large periapical lesion associated with the tooth and this was surgically removed. During the surgical procedure a retrograde cavity was prepared on the calcified root using ultrasonic instruments and this was filled using Super EBA cement. Twelve months later the tooth was asymptomatic and the periapical tissues had completely healed.- - - - - - - - - - ranking = 0.6keywords = tooth (Clic here for more details about this article) |
9/21. Case report of a rare syndrome associating amelogenesis imperfecta and nephrocalcinosis in a consanguineous family.A rare syndrome associating amelogenesis imperfecta (AI) with nephrocalcinosis has been reported. The purpose of this study is to characterise the phenotype of a consanguineous family presenting amelogenesis imperfecta, delayed permanent teeth eruption and nephrocalcinosis. Six family members were examined. Ground sections of the case index deciduous teeth and biopsies of enlarged dental follicles were analysed. The patients's parents were first cousins. The case index had yellow discoloration and altered teeth shapes, retention of deciduous teeth, and delayed eruption. Panoramic radiographs revealed multiple enlarged pericoronal follicles in unerupted teeth and generalised intrapulpal calcifications. Renal ultrasound showed the presence of nephrocalcinosis. No other family members presented enamel defects or nephrocalcinosis. Histologically, the enamel appeared hypoplastic, and dental follicles indicated pericoronal hamartoma. The consanguineous marriage suggests an autosomal recessive mode of inheritance. Further studies are necessary to clarify the genetic defect behind this syndrome that associates AI, nephrocalcinosis and impaired tooth eruption.- - - - - - - - - - ranking = 0.2keywords = tooth (Clic here for more details about this article) |
10/21. Criteria for management of calcific metamorphosis: review with a case report.Calcific metamorphosis is seen commonly in the dental pulp after traumatic tooth injuries and is characterized by deposition of hard tissue within the root canal space. Opinion differs among practitioners as to whether to treat these cases upon early detection of calcific metamorphosis or to observe them until symptoms or radiographic signs of pulpal necrosis are detected. In this article, the clinical, radiographic, and histopathologic appearance of calcific metamorphosis is described; a review of the literature is presented to address these issues in an attempt to establish sound rationale for treatment. Approximately 3.8% to 24% of traumatized teeth develop varying degrees of calcific metamorphosis. Studies indicate that of these, approximately 1% to 16% will develop pulpal necrosis. Most of the literature does not support endodontic intervention unless periradicular pathoses is detected or the involved tooth becomes syptomatic. It may be advisable to manage cases demonstrating calcific metamorphosis through observation and periodic examination. A report of a case where in non-surgical endodontic intervention was successfully carried out a patient suffering from calcific metamorphosis with periapical pathoses is also presented.- - - - - - - - - - ranking = 0.4keywords = tooth (Clic here for more details about this article) |
