Fifteen patients, eight males and seven females with a mean age of 13.32 years, were selected for unilateral molar distalization. Dentally, all presented with a unilateral Class II molar relationship. The subjects were all in the permanent dentition with second molars erupted and with a well aligned lower dental arch. For maxillary molar distalization a new intra-oral appliance was developed, t...

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...

E ctopic eruption of the permanent first molar is a local eruption disturbance in the developing permanent dentition. This abnormal eruption pattern is most commonly seen in the maxillary arch. The abnormal mesioangular eruption path of the maxillary first molar causes resorption of the distal root of the adjacent primary second molar. Progression of ectopic eruption may cause impacted permanen...

There is a growing interest in the relationship between occlusion and posture because of a greater incidence of neck and trunk pain in patients with occlusal dysfunction. The study was designed to verify whether an alteration of the spinal column alignment may be experimentally induced in rats as a consequence of altering dental occlusion and also to investigate whether the spinal column underw...

Introduction: Patients with dental Class II bialveolar protrusion are generally treated by extracting the four first premolars or two first and two second premolars, and retracting the anterior teeth. This case report describes the treatment of an adult patient with bialveolar protrusion, a Class II canine and molar relationship, and lip protrusion. Methods: In this patient, the maxillary right...

The case of an immature natal maxillary first primary molar is reported. Natal molars are rare occurrences, the present instance being only the eighteenth reported case. Clinical and histologic examination revealed that the tooth was rootless, incompletely mineralized, and acutely inflamed. Subsequent radiographs showed that the tooth was actually the primary first molar.

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 purpose of this study was to evaluate treatment effects of Jones jig appliance during class-II molar correction with a focus on the magnitude of maxillary first molar distalization, its tipping, extrusion and rotation as well as anchorage loss at premolarincisor unit. A complete set of pre and post distalization records including history, clinical examination, Lateral cephalometric radiogra...

Ectopic eruption is the abnormal eruption of a permanent tooth that often causes root resorption of an adjacent primary tooth which can be noted during routine dental radiographic evaluation. The mesial eruption of the permanent first molar may be a local eruption problem or may indicate developmental arch circumference deficiency requiring further consideration. Early treatment is mandatory to...
