The purpose of this study was to determine the prevalence of third molars in terms of respondents' age. Furthermore it was desired to determine the extent of the manifestation of pathological changes, such as caries, apical lesions, and alveolar bone resorption. This study was based on 500 OPGs of patients from the Faculty of Dentistry, University of Zagreb. Patients were divided into seven age...

A total of 263 ankyloscd primary molars in 107 children aged three to 12 years was studied for four years. Forty-six children remained in the study for eight years. Observation of affected dentitions showed that the condition was likely to recur. Three clinical pa~terns for the condition are described. Typically, maxillary molars became ankylosed earlier and demonstrated more severe in[raocclus...

The late Eocene prosimian Wadilemur elegans from the Jebel Qatrani Formation, northern Egypt, was originally interpreted as an anchomomyin adapiform primate based on limited information from the lower molars and distal premolars. Recently recovered fossils attributable to this species, including a proximal femur, the fourth upper premolar and first and second upper molars, and a mandible preser...

OBJECTIVE The aim of this study was to investigate the root and canal morphology of maxillary third molars in Central India population using cone-beam computed tomography (CBCT) analysis. MATERIALS AND METHODS CBCT images of 116 maxillary third molars were observed, and data regarding the number of roots, the number of canals, and Vertucci's Classification in each root was statistically evalu...

PURPOSE The objective of this outcome study was to compare ferric sulfate pulpotomy (FS) and primary tooth root canal therapy (RCT) on cariously exposed vital pulps of primary molars. METHODS A total of 291 molars were treated in 130 children--182 molars received FS and 109 received RCT by random selection. RESULTS At 2-year reassessment, 116 molars (73 FS, 43 RCT) were available for clinic...

SETTING The Reception and Primary Care Clinic, Prince Philip Dental Hospital, Hong Kong. DESIGN Retrospective study. SUBJECTS AND METHODS The records of 7486 patients were examined to determine whether the chief complaints were related to impacted teeth an...

OBJECTIVE This study assessed the anterior-posterior positioning of the upper and lower first molars, and the degree of rotation of the upper first molars in individuals with Class II, division 1, malocclusion. METHODS Asymmetry I, an accurate device, was used to assess sixty sets of dental casts from 27 females and 33 males, aged between 12 and 21 years old, with bilateral Class II, division...

The purpose of this study was to measure the shear bond strength of Gluma/Lumifor (Gluma and Lumifor--Columbus Dental, St. Louis, MO) to the occlusal dentin of primary first and second molars, permanent first and second molars and premolars. The data were examined for differences using a one-way analysis of variance and Duncan's Multiple Range test. The shear bond strength, (kc/cm2, x +/- SEM) ...

We describe Lutreolina tonnii sp. nov. (Mammalia, Metatheria, Marsupialia, Didelphimorphia, Didelphidae), recovered from Early (or Early–Middle) Pleistocene deposits of the coastal cliffs near Necochea City in Buenos Aires Province, Argentina. Its holotype, a right maxillary with M1-3, indicates that it belongs to largest species genus, including extinct and extant species. It also differs othe...
