OBJECTIVE The purpose of this study was to investigate the root/number of roots and morphology of mandibular premolars and molars in a Korean population, and to evaluate the prevalence of three-rooted mandibular first molars having distolingual (DL) roots, three-rooted mandibular second molars, and C-shaped roots in mandibular second molars. METHODS Serial axial cone-beam computed tomography ...

The aim of this in vitro study was to measure critical morphology of molar pulp chambers. One hundred random human maxillary and mandibular molars (200 teeth in total) were used. Each molar was radiographed mesiodistally on a millimeter grid. Using a stereomicroscope, the measurements were read to the nearest 0.5 mm. Results were as follows (mean, mm): pulp chamber floor to furcation, maxillary...

the aim of this study was to determine the prognosis and survival for patients with borderlineovarian tumor (bot). a retrospective review of 30 patients with serous andmucinous bot treated at or referred to our institution was performed. fifteenpatients (50%) had serous, and the others had mucinous bot. about 86% of allpatients in both groups were in stage i of the disease. the recurrent diseas...

Although functional appliances have been widely adopted for clinical modulation of mandibular growth for nearly a century, the underlying regulatory mechanism of mandibular condyle growth have been under investigation. Over these years, studies have been focused on both the natural growth of mandibular condyle and its growth modulation by functional appliances at cellular and molecular levels. ...

The form and size of the human mandible is subject to considerable variation from the accepted normal. One of the more interesting and rewarding aspects of oral surgery is the operative correction of the Mandibular abnormalities, the category of malformation into which the mandibular deformity falls. In this study we reviewed more than 30 articles to clarify the mandibular prognathism with its ...

human mandibular premolars have earned the reputation for having an extremely complex root and root canal morphology. the incidence of multiple roots and canals in mandibular second premolars is lower than those in mandibular first premolars. mandibular second premolars with three root canals and separate foramina are very rare. in this case report, endodontic management of a three-rooted mandi...
