Microradiographic and Microhardness Studies of Developing Enamel
This study was undertaken on human and Rhesus monkey enamel using three methods of analysis to gain information concerning the pattern of enamel calcification: (1) microhardness pattern of enamel mineralization; (2) microradiography; and (3) plastic substitution studies. Halves of teeth were selected and tested on a Tukon Microhardness Tester with a Knoop Diamond Indentor. The other half of eac...
متن کاملpostnatal studies of bats (pipistrellus kuhlii and miniopterus schreibersii) & histomorphology and histochemistry studies of organs and diseases of (neurergus microspilotus and n. kaiseri)
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
Destructive effects of citric acid, lactic acid and acetic acid on primary enamel microhardness
Objective: This study aimed to assess the destructive effects of citric acid, lactic acid and acetic acid produced from the fermentation of foods on primary teeth enamel. Methods: This in vitro, experimental study was conducted on 24 sound primary teeth. The teeth were polished with a fine abrasive paper under running water. Tooth pieces measuring 3 × 4 × 3mm were cut out of the teeth and s...
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 کاملEffect of Remin Pro and Neutral Sodium Fluoride on Enamel Microhardness After Exposure to Acidic Drink
Background and Aim: High consumption of carbonated diet soda is the most common etiologic factor for dental erosion. The purpose of this study was to evaluate the microhardness of the enamel surface eroded by cola after treatment with Remin Pro and neutral sodium fluoride. Materials and Methods: This in vitro experimental study was performed on 20 extracted premolars with no corrosion, abras...
