Tooth areas correlate significantly with long bone measurements in a skeletal population of rhesus monkeys from Cayo Santiago. Correlations are relatively large for the troop as a whole, as well as for males and females separately. Femur and humerus length measurements show the higheres correlations with tooth size.

BACKGROUND The patterning cascade model of tooth morphogenesis accounts for shape development through the interaction of a small number of genes. In the model, gene expression both directs development and is controlled by the shape of developing teeth. Enamel knots (zones of nonproliferating epithelium) mark the future sites of cusps. In order to form, a new enamel knot must escape the inhibito...

Tooth loss or damage, such as that caused by dental caries and periodontal disease, can cause fundamental problems with oral functions. The development of regenerative therapy for tooth tissue repair and whole-tooth replacement is currently considered a novel treatment with the potential to fully recover tooth function. Several mesenchymal stem cell-like cell types have been identified in oral ...

In osteichthyans (bony fishes) the dentition is characterized by marginal tooth rows replaced basal resorption. Basal resorption was present in stem osteichthyan Andreolepis, which also possessed overgrowing tooth-shaped odontodes, a possible intermediate state between external odontodes and teeth. however, lacked enlarged found more advanced osteichthyans, how these evolved from condition unkn...

PURPOSE Articulation paper mark size is widely accepted as an indicator of forceful tooth contacts. However, mark size is indicative of contact location and surface area only, and does not quantify occlusal force. The purpose of this study is to determine if a relationship exists between the size of paper marks and the percentage of force applied to the same tooth. MATERIALS AND METHODS Thirt...

Background and purpose: Transverse problems in the maxilla (high arched- narrow hard plates) can cause respiratory disorders. Palatal expansion can be helpful in this way. The present study aimed at evaluating the effect of bone borne expansion and tooth borne palatal expansion on airway volume. Materials and methods: A review study was performed by search in Google Scholar, Scopus, PubMed, Em...

Mice carrying mutations in Wise (Sostdc1) display defects in many aspects of tooth development, including tooth number, size and cusp pattern. To understand the basis of these defects, we have investigated the pathways modulated by Wise in tooth development. We present evidence that, in tooth development, Wise suppresses survival of the diastema or incisor vestigial buds by serving as an inhibi...
