Chemical composition of human enamel and dentin
The theoretical or practical dosimetry involving radiation interactions in humans needs the reliable elemental composition data of body tissues. The object of this research was to obtain the characterization dental hard tissues and to determine its effective atomic number. An analytical research of inorganic composition, from 30 intact human molars, extracted for periodontal reasons, was perfor...
متن کاملDental bleaching with ozone: effects on color and enamel microhardness.
The aim of this in vitro study was to evaluate the effects of dental bleaching with ozone (O3) on color change and enamel microhardness. Enamel blocks (3 x 3 x 3mm) were randomly distributed for treatments (n=10). Color change (ΔE) and Knoop microhardness of the enamel blocks were evaluated before and after the following treatments: C - deionized water (control); HP - 37.5% hydrogen peroxide (P...
متن کاملLight-activated bleaching: effects on surface mineral change on enamel.
AIM This study evaluated the in vitro effect of 35% hydrogen peroxide (HP) on surface enamel change when activated with different light curing units (LCUs). MATERIALS AND METHODS Enamel blocks (4 × 4 × 2 mm) were obtained from bovine incisors. The initial microhardness of the enamel was determined for each specimen. After this enamel blocks were randomly divided into four groups (n = 10) and ...
متن کاملEffect of Office Bleaching Systems on Chemical Compositions of Enamel and Dentin: an in Vitro Study
Background and Aim: To determine the change in the mineral component of enamel and dentin as well as to evaluate the differences in surface texture of the same dental hard tissues following three office bleaching procedures in vitro. Materials and Methods: Sixty extracted human anterior teeth were used. Thirty teeth were used as enamel samples; the buccal surfaces of the remaining 30 teeth were...
متن کاملMicrohardness of demineralized enamel following home bleaching and laser-assisted in office bleaching
BACKGROUND There is little data regarding the effect of tooth whitening on microhardness of white spot lesions. This study was conducted to investigate the effect of home-bleaching and laser-assisted in-office bleaching on microhardness of demineralized enamel. MATERIAL AND METHODS Forty bovine incisors were selected and immersed in a demineralizing solution for 12 weeks to induce white spot ...
