Congenitally missing teeth are frequently presented to the dentist. Interdisciplinary approach may be needed for the proper treatment plan. The available treatment modalities to replace congenitally missing teeth include prosthodontic fixed and removable prostheses, resin bonded retainers, orthodontic movement of maxillary canine to the lateral incisor site and single tooth implants. Dental imp...

Double or fusion of the teeth is a primary developmental anomaly union of two independently developing primary or permanent teeth. The tooth fusion may contribute to various significant problems such as crowding, caries and periodontal diseases and they may be associated with anomalies in the succeeding permanent dentition which necessitate careful examination & proper treatment planning becaus...

Objective: The objective of this study was to investigate the relationship between age, gender and clinical crown length using a longitudinal study design. Method: Four hundred and fifty-six sets of study models initially obtained for a large prospective longitudinal cohort study of orthodontic needs were examined. Each set of models corresponded to subjects at three different ages: 11–12, 14–1...

OBJECTIVES The aim of this study was to evaluate the effects of damping on stress concentration in an impacted incisor. METHODS Damping ratios of maxillary incisors were tested using an in vivo modal testing method. A finite element model of the upper central incisor was established for dental trauma analysis. To assess the effect of damping properties on induced stresses in the traumatized i...

an accurate diagnosis of the morphology of the root canal system is a pre-requisite for successful root canal treatment. frequently, root canals are left untreated because the clinicians fail to identify their presence, particularly in teeth that have anatomical variations or additional root canals. in this report a maxillary lateral incisor with two roots has been described.

A peptide that is rich in organically bound phosphorus and contains abundant serine residues has been identified in the dentin of man (1), fetal bovine (2, 3), and rat (4). This phosphoprotein may play a role in mineralization (5-9). Butler et al. (4) reported that the phosphoprotein of rat incisor dentin constituted 10.8% of the proteinaceous material recovered from decalcified incisor teeth w...

The aim of this study was to re-examine Leon Williams geometric theory and to find the degree of correspondence between the face and the tooth form in the population of Zenica, Bosnia and Herzegovina. Two thousand individuals with intact frontal teeth, in age between 17 and 24 years, were measured for 3 horizontal distances on the face: temporal width (Ft-Ft), zygomatic width (Zyg-Zyg) and goni...

The orthodontic management of congenitally missing maxillary lateral incisors has three common treatment approaches: space closure by means of canine substitution, the placement of an endosseous dental implant, and a tooth supported restoration. Replacement of the missing teeth with an endosseous dental implant is a viable option, especially when adjacent teeth are healthy and unrestored ( Koki...
