OBJECTIVE The aim of the present study was to evaluate the demographic profile of supernumerary molar (SM) teeth in people in various regions of Turkey. STUDY DESIGN A retrospective analysis was carried out on an initial sample of 104,902 subjects drawn from the ortopantographics files from 10 clinics in 7 Turkish cities with documentation of demographic data, the presence of SM teeth, their ...

Bruxism is the ineffective rubbing of the lower teeth into the upper teeth. In daily use among people, it is called tooth grinding disease. Bruxism is usually a phenomenon that occurs during exercise or when the person feels nervous at the moment when strong jaw movements cause jaw tightening and teeth grinding. It is common in our society, but in general, individuals are not aware of these hab...

Chipped and broken functional teeth are common in modern sharks with serrated tooth shape. Tooth damage consists of splintering, cracking, and flaking near the cusp apex where the enameloid is broken and exposes the osteodentine and orthodentine. Such damage is generally viewed as the result of forces applied during feeding as the cusp apex impacts the skeletal anatomy of prey. Damage seen in s...

The supplemental tooth is of normal shape and size resembling a particular tooth from the normal dentition. These teeth might cause esthetic and/or functional problems because they are usually located in the maxillary anterior region. This is a case report of a patient who had visual discomfort from the color of his teeth and requested esthetic treatment. On intraoral examination, a supplementa...

In this paper, we describe a solid freeform fabrication procedure for human dental restoration via porcelain slurry micro-extrusion. Based on submicron-sized dental porcelain powder obtained via ball milling process, a porcelain slurry formulation has been developed. The formulation developed allows the porcelain slurry to show a pseudoplastic behavior and moderate viscosity, which permits the ...

Due to the complexity of the dental models in semantics of both shape and form, a fully automated method for the separation of the lower and upper teeth is unsuitable while manual segmentation requires painstakingly user interventions. In this paper, we present a novel interactive method to segment the upper and lower teeth. The process is performed on 3D triangular mesh of the skull and consis...

Teeth are specialized structural components of the craniofacial skeleton. Developmental defects occur either alone or in combination with other birth defects. In this paper, we review the dental anomalies in several multiple congenital anomaly (MCA) syndromes, in which the dental component is pivotal in the recognition of the phenotype and/or the molecular basis of the disorder is known. We wil...
