PURPOSE The purpose of this study was to determine which materials were most commonly used by pediatric dentists in California to restore Class II lesions in the primary dentition. METHODS A questionnaire consisting of 18 multiple-choice questions was mailed to all 440 active members of the California Society of Pediatric Dentistry (CSPD). The questions related to the practitioners' material ...

PURPOSE The purpose of this study was to determine the prevalence of missing and impacted third molars in people aged 25 years and above. MATERIALS AND METHODS The study sample of 3,799 patients was chosen randomly from patients who visited Pusan National University Dental Hospital and had panoramic radiographs taken. The data collected included presence and impaction state, angulation, and d...

conclusions most extracted maxillary first molars were three rooted and four canals. cbct has relatively high reproducibility and accuracy of distinguishing mb2 canal. results we found 100% of cases with three separated roots, from which 69.23% had four canals including mb2 and 30.77% with three canals. 71.3% of mesiobuccal roots were two canals of type two vertucci and 28.7% type 4 with the me...

PURPOSE The purpose of this study was to compare long-term outcomes of ferric sulfate pulpotomy (FS) and primary tooth root canal therapy (RCT) in vital pulps of deciduous molars exposed to caries lesions. METHODS A total of 291 molars were treated in 130 children. One hundred and eighty-two molars received FS and 109 received RCT by random selection. RESULTS At 3-year re-assessment, 29 mol...

Using a novel coordinate system, we rederive the eld equations and equations of motion for 5-dimensional relativity in the general case where the metric can depend on all 5 coordinates (i.e., Kaluza-Klein theory without the cylinder restriction). We show that in general the fth dimension produces a new dynamical force in 4-dimensional spacetime. This timelike fth force is proportional to the 4-...

AIM To evaluate the root canal configuration of permanent mandibular first and second molar teeth in a Chinese subpopulation using cone-beam computed tomography (CBCT). METHODOLOGY Patients who required CBCT radiographic examinations as part of their routine examination, diagnosis and treatment planning, were enrolled. Cases where the anatomy was compromised by physiological or pathological p...

The topics addressed are: Natural History of Third Molars Conclusions Periodontal Considerations in Third Molar Removal Conclusions—presence of impacted third molars Conclusions—third molar removal Conclusions—reduction in post-operative loss of periodontal attachment Conclusions—periodontal disease severity/progression Microflora Around the Second and Third Molars Conclusions Effects of Age on...

The occurrence of supernumerary teeth is a relatively uncommon dental anomaly and it's rare for patients to have impacted fourth molars in all quadrant. Aim of this work is to describe the presence of bilateral fourth molars in the maxilla and the mandible in a young male patient aged 22 years came to our hospital with acute pericoronal infection around unerupted third inferior molars. Routine ...
