A common failure in endodontic treatment of the permanent maxillary first molars is likely to be caused by an inability to locate, clean, and obturate the second mesiobuccal (MB) canals. Because of the importance of knowledge on these additional canals, there have been numerous studies which investigated the maxillary first molar MB root canal morphology using in vivo and laboratory methods. In...

We report the case of a 38-year old male patient with sinusitis caused by an infected follicular cyst due to an ectopic impacted third molar in the right maxillary sinus. A 10-day antibiotherapy regimen was administered; subsequently, the cyst and the third molar were removed achieving complete recovery. Fibrous dysplasia was diagnosed at follow-up examination (occupation of the maxillary sinus...

Endodontic treatment may sometimes fail because morphological features of the tooth adversely affect the treatment protocol. Maxillary second molars are recognized as usually having a single palatal root with a single palatal canal. The incidence of second palatal root in the maxillary second molar is very rare. Two cases are presented in this paper describing the endodontic management of a fou...

Correction of class II molars in growing patients with acceptable facial profile can be performed by distalization of maxillary first molars. However, in patients where compliance is difficult intraoral means of molar distalization is required. This case report describes the use and effectiveness of a novel 2K appliance in an 11-year-old female having an orthognathic profile, skeletal Class I r...

We report here on our application of the socket lift technique to create a transplant socket for the transplanted maxillary molar. These outcomes suggest that this technique is likely to be effective for tooth transplantation when the maxillary sinus bottom is close to the alveolar crest.

PURPOSE Few epidemiologic studies have investigated aggressive periodontitis in Koreans, but such studies of disease prevalence and other clinical characteristics would be invaluable in providing proper treatment. The aim of this study was to assess the prevalence of aggressive periodontitis and to measure the extent of associated periodontal breakdown. METHODS The study population consisted ...

The orthodontic treatment of an adult patient with a skeletal Class III malocclusion, increased anterior facial height, negative overjet, and bilateral posterior crossbite is presented. Treatment options included mandibular first premolar or third molar extractions with dentoalveolar compensation or combined surgical-orthodontic treatment. Mandibular third molar extraction with dentoalveolar co...

This case report presents an uncommon case of maxillary molar with two palatal root canals and an enamel pearl in the furcation area. The article discusses root canal complexities of maxillary second molars as well as possibility of coexisting anomalies in the region that makes radiographic interpretation difficult and compromises the success of endodontic treatment.

Taurodontism can be defined as a change in tooth shape caused by the failure of the Hertwig's epithelial sheath diaphragm to invaginate at the proper horizontal level. An enlarged pulp chamber, apical displacement of the pulpal floor, and no constriction at the level of the cementoenamel junction are the characteristic features. Permanent molars are most commonly affected. Endodontic treatment ...

Congenital morphological dental alterations are related to the physiological phase of tooth development. Since the etiology of the dens invaginatus and supernumerary roots has yet to be fully determined, a rare presentation of dens invaginatus in a primary molar and a birooted deciduous maxillary canine were incidentally detected in routine radiographic examinations. Essential clinical consider...
