Further knowledge concerning the spontaneous occurrence of dental caries in animals as well as in man is necessary in. order to shed more light on the etiology of this disease. The present communication reports the incidence and the clinical and histological descriptions of lesions in the teeth of monkeys.t These lesions are similar to or identical with those found in man. The dentitions of a c...

The Journal of Clinical Pediatric Dentistry Volume 33, Number 4/2009 289 INTRODUCTION Tooth banking is based on the firm belief that personalized medicine is the most promising avenue for treating challenging diseases and injuries that could occur throughout lifetime. Stem cell therapy has been used around the world to treat such conditions, and the full promise of stem cell therapy has only be...

In postnatal dental development, and in crown size itself, there is a demonstrable "distance gradient" so that teeth closer together within a jaw quadrant show higher correlations. Thus, adjacent teeth exhibit systematically higher commonality in both tooth formation and crown size than more remote teeth in the same quadrant, despite absolute differences in formation (calcification, root elonga...

Dilaceration is a dental deformity characterized by an angulation between crown and root causing non-eruption of the tooth. It generally occurs following trauma to the deciduous dentition the apices of which lie close to the permanent tooth buds. Surgical extraction used to be the first choice in treating the severely dilacerated teeth. In this case report, it is described how a dilacerated cen...

Background: Odontogenic tumors are derived from the epithelial and/or mesenchymal remnants of the tooth-forming apparatus. Therefore, they are found exclusively in tooth-bearing areas. Similar to other neoplasms in the body, odontogenic tumors tend to histologically mimic the cell or tissue of origin. Case history: A 5-year-old boy presented with a chief complaint of pain in the mandible whi...

Recessive dystrophic epidermolysis bullosa of Hallopeau-Siemens (RDEB-HS) is a rare genetic disorder characterized by trauma-induced blisters, milia, acral pseudosyndactyly, and scarring. RDEB-HS patients present with a distinct pattern of oral involvement consisting of microstomia, ankyloglossia, vestibule obliteration and dental caries. In this review, we describe the orodental manifestations...

This study deals with correlations of tooth size in human primary teeth. Traditionally, mesiodistal or buccolingual measurements have been used to express crown size. However, in this study, crown area was used as a reference parameter. Graphic reconstructions of 38 histologically prepared human fetuses with Crown-Rump Length (CRL) between 54 and 280 mm were used to obtain linear and area measu...

The dilated odontoma is an infrequent developmental alteration that appears in any area of the dental arches and can affect deciduous, permanent and supernumerary tooth. Dens invaginatus is a developmental anomaly resulting from invagination of a portion of crown forming within the enamel organ during odontogenesis. The most extreme form of dens invaginatus is known as dilated odontoma. The aim...

Lamellae or cracks are distributed throughout tooth enamel in both deciduous and permanent dentitions. While earlier authors postulated that lamellae may be pathways of entry for caries, no evidence was adduced and the theory appears to have been discounted. The present study seeks to show that, at least in some cases, lamellae are permeable to dyes, may be associated with caries initiated in t...
