We explore the functional, developmental, and evolutionary processes which are argued to produce tooth reduction in the extinct marine reptile Stenopterygius quadriscissus (Reptilia: Ichthyosauria). We analyze the relationship between mandible growth and tooth size, shape, and count, to establish an ontogenetic trend. The pattern in S. quadriscissus is consistent with hypotheses of tooth size r...

AIM The purpose of this report is to present a case of endodontic management of a dilacerated maxillary central incisor fused to supernumerary tooth unusually appearing as a labial tubercle using cone beam computed tomography (CBCT) as a diagnostic aid. BACKGROUND Anterior teeth are commonly encountered with aberrant anatomical variations in the crown, number of roots, and root canals. Fusion...

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...

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

In this paper, we are interested in the application to video segmentation of the discrete shape optimization problem

We consider a non-local shape optimization problem, which is motivated by a simple model for swarming and other self-assembly/aggregation models, and prove the existence of different phases. A technical key ingredient, which we establish, is that a strictly subharmonic function cannot be constant on a set of positive measure.

The behaviour of solutions to fourth order problems is studied through the decomposition into a system of second order ones, which leads to relaxed formulations with the introduction of measure terms. This allows to solve a shape optimization problem for a simply supported thin plate. Ref. S.I.S.S.A. 32/97/M (March 97) Asymptotic behaviour of solutions of fourth order Dirichlet problems 1
