The sequence and timing of permanent tooth eruption is thought to be highly heritable and can have important implications for the risk of malocclusion, crowding, and periodontal disease. We conducted a genome-wide association study of number of permanent teeth erupted between age 6 and 14 years, analyzed as age-adjusted standard deviation score averaged over multiple time points, based on child...
BACKGROUND Equine incisors are subjected to continuous occlusal wear causing multiple, age related changes of the extragingival crown. It is assumed that the occlusal wear is compensated by continued tooth elongation at the apical ends of the teeth. In this study, μCT-datasets offered the opportunity to analyze the three-dimensional appearance of the extra- and intraalveolar parts of the enamel...
BACKGROUND Feeding mode during infancy and its effect on deciduous tooth appearance in oral cavity in two generations and among genders. AIM AND OBJECTIVE Study aimed to compare and correlate times and patterns of deciduous tooth eruption in breastfeeding (OBF), partial breastfeeding (PBF) and spoon feeding (SF) infants and initiation of semisolid food feeding (SSF) in infants.

The term odontoma was first coined by Broca in 1866, who defined it as a tumour formed by overgrowth of complete dental tissue. Odontoma has also been defined as ‘tu...
A case is presented which demonstrates the incomplete transposition of a posterior tooth. In this case, the path of eruption of an abnormally angulated developing mandibular second premolar was diverted distally following the extraction of the adjacent first

Dilacerations generally involve central incisors; most often maxillary incisors rather than their mandibular counterparts. The clinical features of dilaceration include non-eruption the responsible tooth or prolonged retention deciduous predecessor tooth. In Case 1, showed a at boundary between crown and root, more laterally labiolingually. 2, dilacerated with relatively normal orientation dent...
