The Role of Serum Vitamin D Levels and Vitamin D Receptor () Gene Variants on Dental Caries.

Background/objectives: Vitamin D helps the mineralization of bone, teeth, and other calcified tissues by regulating calcium-phosphate metabolism. The nuclear activation of the vitamin D receptor () gene is essential for the effectiveness of vitamin D. The main objective of this study is to determine the role of vitamin D levels and gene variants in dental caries.

Evaluation of Glass-Ionomer versus Bulk-Fill Resin Composite: A Two-Year Randomized Clinical Study.

Background: The aim of this split-mouth design research was to compare the clinical performance of a glass-ionomer cement system on Class I/II cavities against the clinical performance of bulk-fill resin composite restoration materials. Methods: Thirty-five patients were randomized and enrolled in the study, aged between 10 and 12 years, all of whom had a matched pair of permanent mandibular carious molars with similar Class I/II. A total of 70 restoration placements were performed.

Comparative evaluation of fluoride varnishes, self-assembling peptide-based remineralization agent, and enamel matrix protein derivative on artificial enamel remineralization in vitro.

Background: One of the most unfavorable side effects of fixed orthodontic treatment is white spot lesions (WSLs). Although the most important approach is prevention of WSLs, it is also essential to evaluate the efficacy of the remineralization agents. However, there is no concurrence in the literature with respect to the remineralization process of these agents.

Temperature-dependent erosivity of drinks in a model simulating oral fluid dynamics.

Objectives: Aim of this investigation was to study the temperature-dependent in vitro enamel erosion of five acidic drinks and citric acid under controlled conditions in an artificial mouth.

Methods: The erosive potential of Orange juice, Coca-Cola Zero, Sprite Zero, two fruit teas and citric acid (control) was investigated on bovine enamel specimens at temperatures between 5 °C and 55 °C. The pH values and total calcium content of all test drinks were determined.

Color assessment after bleaching with hydrogen peroxide versus ozone: a randomized controlled clinical trial.

This randomized controlled clinical trial evaluated the color change of teeth bleached with either hydrogen peroxide (HP) or ozone (OZ). A total of 26 patients with a mean age of 36.2 years (SD, 8.
