Gemination aka twinning and fusion, are rare occurrences in posterior mandibular teeth, often requiring endodontic and surgical treatment for functional, orthodontic or cosmetic reasons. The diagnosis and design of a precise treatment plan in cases involving double teeth are in most cases challenging. The purpose of this case report is to describe a successful multidisciplinary treatment protoc...

The normal and lateral line cycloid scales of a cyprinid fish Rutilus frisii kutum Kamenskii, 1901 have been subjected to scanning electron microscopy technique to study their detailed structure. The scales have the general morphological characteristics of the cycloid scales. In the normal scale located below the dorsal fin, the focus lies on the anterior region with few mucous pores. There is ...

An increased number of teeth in relation to normal dental formula is called hyperdontia, and the additional tooth are termed as supernumerary tooth. A supplemental a that closely resembles shape its adjacent with which they associated supplements for occlusion. Primary dentition presents lower prevalence compared permanent dentition. This report primary

This article describes an esthetic rehabilitation of a case of severe fluorosis associated with tooth mobility and gingival recession. Direct composite technique was applied to improve the color, shape and alignment of the teeth using direct composite veneering and replacement of the missing tooth by fiber-reinforced composite bridge. One year follow up have displayed acceptable outcomes and es...

We report the first successful synthesis and characterization of single-crystal wurtzite CdSe nanoribbons through a simple thermal evaporation process. Asymmetric growth of the nanoribbons occurs, yielding a sawlike shape with sharp teeth on one side. This asymmetric growth is suggested to be induced by the polarization of the c-plane in the wurtzite crystal structure.

The aim of this study was to investigate the possible relationship between interfacial forces, duration of instrumentation and effectiveness of root canal shaping by filing. All factors were standardised except the manner of manipulation of the files and the dependent variables (interfacial force and duration of filing). The outcome measured was the final prepared canal shape. The study tested ...

background: since there has been no published report on the impact of permanent canines in shiraz population, this study was conducted to investigate the prevalence and the location of the impacted permanent canines in patients referred to the department of radiology of shiraz dental school in 2012. materials and methods: this was an analytic cross-sectional study on 1012 panoramic radiographs....
