Autogenous tooth transplantation, or autotransplantation, is the surgical movement of a tooth from one location in the mouth to another in the same individual. Once thought to be experimental, autotransplantation has achieved high success rates and is an excellent option for tooth replacement. Although the indications for autotransplantation are narrow, careful patient selection coupled with an...

Teeth and bones are frequently the only sources of DNA available for identification of degraded or fragmented human remains. The unique composition of teeth and their location in the jawbone provide additional protection to DNA compared to bones making them a preferred source of DNA in many cases. Despite this, post-mortem changes in the structure and composition of teeth, and the location and ...

The purpose of this study was to establish tooth width and arch dimensions in normal and malocclusion samples and to compare tooth width and arch dimensions between males and females in normal and malocclusion samples. A total of 120 pairs of orthodontic study casts were included in the study. An electronic digital caliper was used for the measurements. Descriptive statistics and the t-test wer...

Computer-aided tooth shade determination of the natural tooth is an emerging application area which is still in development. Selecting the correct porcelain type is the key to repair teeth successfully. But the color and shade determined by human observers could not achieve a satisfied result because of the effect of the surrounding light and the limit of human eyes. And the computer-aided toot...

The differences in tooth colour are important factors in the esthetic dentistry. The aim of this study was to determine the tooth colour using visual methods under natural light and "Easy Shade" device. Five hundred patients of Dental Clinic Graz Austria were selected for this study. The results of this study showed that the shade matching using "Easy Shade" device were not better than shade ma...

Scans of the human genome have identified many loci as potential targets of recent selection, but exploration of these candidates is required to verify the accuracy of genomewide scans and clarify the importance of adaptive evolution in recent human history. We present analyses of one such candidate, enamelin, whose protein product operates in tooth enamel formation in 100 individuals from 10 p...

Research has shown that tooth loss results in morphological changes in alveolar ridge that may influence the subsequent implant placement. Immediate implant placement was introduced as a possible means to limit bone resorption and reduce the number of surgical procedures following tooth extraction. Histological and clinical evidence from human clinical studies showing efficacy of immediate impl...

Introduction: Revascularization is the newest treatment proposed for an immature permanent tooth with necrotic pulp. Revascularization is defined as a treatment process with a biological base which is aimed at replacing the lost structures and the continued development of roots. Case presentation: Patient was an eight-year-old child with the history of trauma to the maxillary anterior region. ...

OBJECTIVES Tooth loss appears to have an important role in the loss of mastication and esthetics. The aim of this systematic review was to investigate the prevalence of tooth loss and edentulism in the Iranian population. METHODS Studies reviewed in this article were primarily identified via search of the online bibliographic databases including PubMed and Iranian Biomedical Journals, by usin...

We explored the relationship between growth in tooth root length and the modern human extended period of childhood. Tooth roots provide support to counter chewing forces and so it is advantageous to grow roots quickly to allow teeth to erupt into function as early as possible. Growth in tooth root length occurs with a characteristic spurt or peak in rate sometime between tooth crown completion ...
