Although oral dental tissue is a vertebrate attribute, trunk dental tissue evolved in several extinct vertebrate lineages but is rare among living species. The question of which processes trigger dental-tissue formation in the trunk remains open, and would shed light on odontogenesis evolution. Extra-oral dental structures (odontodes) in the trunk are associated with underlying dermal bony plat...

OBJECTIVE To compare the mean dental maturity amongst three vertical facial patterns (short, average and long anterior facial heights) and also amongst two sagittal facial patterns (skeletal class I and II) in orthodontic patients. STUDY DESIGN Cross-sectional analytical study. PLACE AND DURATION OF STUDY The Aga Khan University Hospital, Karachi, from August to October 2008. METHODOLOGY ...

Abnormalities of dental development and eruption occur quite commonly in the horse and result in a wide range of clinical conditions. A congenital/developmental problem present at the time of tooth eruption often leads to acquired dental problems as the teeth continue to erupt and wear. Consequently, several different dental abnormalities whose pathogenesis may be inter-related, are often prese...

means of the well-known method of irradiation followed by testing with BTfecessive-marker stocks, many visible mutants at specific loci have been obtained in mice by several investigators. In some instances the mutants so obtained are presumably identical with the markers employed in the tester stock, but very often distinctive new alleles are involved. These latter may be of intrinsic interest...

The time at which orthodontic treatment should be started remains a matter of conjecture. Anomalies of dental development and functional problems tend to be addressed in the mixed dentition, while definitive treatment tends to be delayed until the late mixed dentition to maximize growth potential and patient compliance. However, some clinicians advocate starting treatment earlier in certain typ...

Parathyroid hormone (PTH) is essential for calcium and phosphate homeostasis in odontogenesis-related cells. Therefore, the present study aimed to investigate association between single nucleotide polymorphisms gene encoding PTH, dental caries Brazilian children. Three hundred fifty-three children (170 boys 183 girls, age ranging from 8 11 years old) were included this study. The International ...

Introduction: Dentinogenesis is regulated by cytokines and growth factors, and modulated by alterations in the extracellular microenvironment. Dental matrix protein-1 (DMP-1), which is predominantly expressed in odontoblasts, is required during the early and late stages of odontogenesis. In the present study, we examined the involvement of proinflammatory cytokines in the expression of odontoge...
