 Dental implants, as a result of their excellent success rates and advantages over fixed or removable methods, have become the optimal treatment for replacing missing teeth. Surgical and restorative techniques that can reduce the loss of hard and soft tissues that often accompany implant placement are desirable. Achieving an esthetic outcome in tooth replacement and implant treatment requires a...

While >50 genes have been found to influence the development of teeth in mice, we still know very little about the genetic basis for the adaptive characteristics of teeth, such as size and shape. We applied interval mapping procedures to Procrustes size and shape data obtained from 10 morphological landmarks on the mandibular molar row of the F(2) progeny from a cross between the LG/J and SM/J ...

Panoramic X-Ray images are very popular as a first tool for diagnosis in odontological protocols. Automating the process of analysis of such images is important in order to help dentist procedures. In this process, teeth segmentation from the radiographic images and feature extraction are essential steps. In this paper, we propose a segmentation approach based on mathematical morphology, quadtr...

The purpose of this study was to investigate the anatomical features of C-shaped root canal system in mandibular second molars using micro-computed tomography (microCT). Fifty-eight extracted mandibular second molars with fused roots were collected from a native Chinese population. The teeth were scanned into layers of 0.5-mm thickness by microCT and measurements were made at eleven levels. The...
