background and aims. gingival recession (gr), a common problem in periodontium, is associated with various etiologic factors. there is controversy over the role and importance of these factors. the aim of this study was to evaluate the etiologic factors of gr in a group of subjects in northwest iran. materials and methods. in this case-control study, patients referring to a university clinic (1...

Tooth crown dimensions are reasonably accurate predictors of sex and are useful adjuncts in sex assessment. This study explores the utility of buccolingual (BL) and mesiodistal (MD) measurements in sex differentiation when used independently. BL and MD measurements of 28 teeth (third molars excluded) were obtained from a group of 53 Nepalese subjects (22 women and 31 men) aged 19-28 years. Step...

This study aimed to evaluate the biomechanical behaviour of adhesive endo-crowns and the influence of their design on the restoration prognosis when four loading positions are applied from the restoration-tooth junction. Two three-dimensional finite element models for the lower first molar were developed: endo-crown as a monobloc and endo-crown of a primary abutment and a full crown. Four crown...

background and aims: to obtain maximum advantages from orthodontic fixed appliances and to achieve the desired final occlusion, correct bracket positioning is highly necessary. in order to measure and determine bracket’s height, diverse gauges have been used. the objective of the present study is to determine and compare bracket positioning accuracy by using height bracket positioning gauge (hb...

BACKGROUND AND AIMS The aim of this study was to determine whether variations in the mesiodistal dimensions of mandibular canines had any role in sex determination. MATERIALS AND METHODS The study comprised of patients in the 19‒24-year age group (20 males and 20 females). Mesiodistal dimensions of mandibular canines was measured at the maximum mesiodistal width, first intraorally, then on pl...

STATEMENT OF PROBLEM In rehabilitating edentulous patients, selecting appropriately sized teeth in the absence of preextraction records is problematic. PURPOSE The purpose of this study was to investigate the relationships between some facial dimensions and widths of the maxillary anterior teeth to potentially provide a guide for tooth selection. MATERIAL AND METHODS Sixty full dentate Mala...

Malformed or congenitally missing teeth are a problem often faced by both orthodontists and restorative dentists. Between 1% and 2% of the population will exhibit a shape modification of the maxillary lateral incisor commonly referred to as a peg lateral. The inheritance of the peg-shaped lateral incisors has been associated with the genotype that causes missing lateral incisors, and the shape ...

Esthetic anterior dental appearance depends on the alignment, occlusion, and exposure of anterior teeth.1–3 In order to establish adequate alignment and occlusion, the upper and lower incisors need to be proportional in size. Interarch tooth size discrepancy (ITSD) is defined as a disproportion in the mesiodistal dimensions of teeth of opposing dental arches. In the absence of a proportional ma...
