the purpose of this study was to evaluate the effect of er:yag laser on the shear bond strength of resin modified glass ionomer (rmgi) to enamel.twenty extracted caries-free human premolars were selected. the teeth were embedded in acrylic resin. the buccal surfaces of each sample were ground to plane enamel with carbonated disc. the teeth were randomly divided in two groups. in the first group...

In the frame of a tree species identifying mobile application, designed for a wide scope of users, and with didactic purposes, we developed a method based on the computation of explicit leaf shape descriptors inspired by the criteria used in botany. This paper focuses on the characterization of the leaf contour, the extraction of its properties, and its description using botanical terms. Contou...

A new species of salamander, Hynobius yangi, is described from Kori (=Hyoam-ri), Busan-shi, southeastern Korea. It is a lentic breeder belonging to the H. nebulosus species group, and has long been confused with another Korean species H. leechii. The new species, however, is genetically substantially differentiated from Korean and Japanese relatives. Hynobius yangi is morphologically very simil...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2015210663 DESCRIPTION Supernumerary teeth are additional teeth present in dentition and are more common in permanent dentition, however, they are a rare finding in primary dentition and can be due to various genetic or environmental factors. The majority of supernu...

hyperdontia or supernumerary teeth in both arches without any syndromic manifestation are extremely rare. supernumerary teeth are commonly associated with gardner’s syndrome, cleft lip and palate, cleidocranial dysplasia and trichorhinophalangeal syndrome. five cases of non-syndromic multiple premolars of maxillary and mandibular arches in indian patients are presented here. this case series re...

statement of problem: knowledge of internal anatomy of tooth plays an important role in a successful endodontics treatment. for a proper endodontic treatment, it is not only important to know the form of normal anatomy of tooth’s interior but one must also be acquainted with the possible diverse forms. purpose: a thorough understanding of the internal anatomy of human mandibular incisors (centr...

Mandibles and teeth of ungulates have been extensively studied to discern the functional significance of their design. Grazing ungulates have deeper mandibles, longer coronoid processes, flatter incisor arcades, and more hypsodont molars in comparison to browsers. If the functional significance of both mandible and teeth shapes is well-established, it remains uncertain to what extent mandible s...

Modeling of the occlusal surface of teeth is an important problem in computer-aided design of dental restorations. The designed shape must t the existing individual anatomy of the patient. Also, the design process must be fast to be practical in clinical applications. In this paper we present a technique for automatic adaptation of the oc-clusal surface for the restoration of teeth based on geo...
