When an esthetic restoration with minimal tooth reduction is desired, for example in patients with uncomplicated tooth fractures, composite partial coverage crowns may be a therapeutic option. The indirect composite restoration allows restoration of the original tooth anatomy, function, and esthetics to be reproduced while preserving tooth structure. The use of composite partial coverage crowns...

AIM Dentigerous cyst (DC) is a disembriogenetic lesion. The cyst wall encloses the crown of an impacted tooth. Several therapeutic approaches have been mentioned in the literature for management of this lesion. Case Report This article describes the management of an adolescent with a mandibular DC surgically treated with extraction of the tooth, enucleation of the cyst and replantation of th...

The aim of the study was to evaluate factors involved in tooth surface loss due to consumption of dried-roasted seeds. Data of tooth surface loss were collected from a group of 141 patients by clinical examination, interview and by getting the questionnaire regarding dietary factors, oral hygiene practices and pregnancy (for women) filled. No significant differences in tooth surface loss were f...

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...

Tooth fusion consists of the union of crowns by the enamel and/or dentin. We describe a case of a patient who presented with a fistula in the apical portion of teeth 32 and 33. Clinically, tooth 32 showed increased crown width in relation to other teeth in the same arch. Radiographic examination evidenced fusion of tooth 32 with a possible supernumerary tooth. Cone-beam computed tomography was ...
