Dentinogenesis Imperfecta (DI) or hereditary opalescent dentin is inherited in a simple autosomal dominant mode with high penetrance and low mutation rates. It generally affects both the deciduous and the permanent dentitions. DI corresponds to a localized form of mesodermal dysplasia which is observed in the histo-differentiation. An early diagnosis and treatment are therefore fundamental, whi...

Amelogenesis Imperfecta (AI) is a genetic disease affecting primary and permanent tooth enamel. The incidence varies between 1:700 to 1:4000. The clinical findings include enamel defects, tooth sensitivity, poor dental aesthetics, reduced vertical dimension, dentin dysplasia, and pulpal calcification. Effective treatment planning should incorporate numerous factors such as the patient’s age, di...

background & aim: regional odonto dysplasia (rod) is an unusual nonhereditary of teeth with significantly clinical and radiographic features. affected teeth usually remain unerupted or semi-erupted with a discolaration and irregular shape. radiographically these teeth have a large pulp chamber and thin layer of enamel and dentin with similar density. this article is introducing a female patient...

This study evaluated the influence of time after application of oxalate solutions in reducing dentin hydraulic conductance. Fifty dentin discs were obtained from extracted human third molars and assigned to 5 groups (n=10), according to the desensitizing agent used: Group I: OxaGel; Group II: experimental agent DD-1: Group III: experimental agent DD-2. In Groups IV and V, a placebo gel and deio...

OBJECTIVE The aim of the present study was to investigate the incidence of dentinal microcracks caused by different preparation techniques. MATERIALS AND METHODS 120 extracted human mandibular incisor teeth were divided into five experimental groups and one control group (n = 20): Group 1: Hand preparation with balanced force technique up to #25 K-file. Group 2: Preparation with only ProTaper...

Ectodermal dysplasia is a hereditary disorder characterized by the absence or defect of two or more ectodermally derived structures. These structures include teeth, hair, skin, nails, and sweat glands. Oligodontia, anodontia, and dysmorphic teeth have been reported in both the primary and permanent dentition of affected individuals. Hair tends to be sparse and very fine while skin is dry due to...

The object of this study was to investigate the relationship between the staining behavior of the carious dentin by the caries detector solution and the structural characteristics of the dentin. Using 160 human extracted caries teeth, the ground and polished sectioned surface and the cutting surface of the caries cavities were prepared. The surface stained by the detector solution was examined ...

KOSTAS VERDELIS: Study Of Mineral And Matrix Maturation In Dentin (Under the direction of Adele L. Boskey and J. Timothy Wright) Spectroscopic analysis was used to study the patterns of changes in the mineral and matrix properties of dentin during maturation of the tissue. Fourier Transform Infrared Imaging (FTIRI) analyses on undecalcified semi-thin sections from fetal bovine incisors and deve...
