Radiopacity of Posterior Restorative Materials: A Comparative In Vitro Study.

Background: The objective was to investigate the radiopacity of 11 commercial posterior restorative materials by establishing their mean gray values (MGVs) and comparing them with dental hard tissues.

Methods And Materials: Five-disc specimens were prepared for each of the following materials: Cerasmart 270 CAD/CAM block A3LT (CS), Amalgam (A), Ketac Molar A3 (KM), Cention-N A2 (CN), G-aenial Universal Flo AO2 (GO2) and A2 (G2), Ever-X Flow Dentine (EXD) and Bulk (EXB) shades, Equia Forte HT Fil A2 (EF2) and A3 (EF3), and Equia Fil A3 (E3). Freshly extracted maxillary premolar teeth were used as a control.

The Use of Toothpastes Containing Different Formulations of Fluoride and Bioglass on Bleached Enamel.

To investigate the application of toothpaste either containing calcium sodium phospho-silicate bioglass (NovaMin) or calcium fluorosilicate bioglass (BioMinF) on the surface mineral composition and morphology of enamel after bleaching procedure. Thirty extracted noncarious human teeth were allocated into five groups (n = 6). Bleaching using 40% hydrogen peroxide (HP) and fluoridated toothpaste containing bioactive glass (1450 ppm fluoride).

Follow-up of flowable resin composites performed with a universal adhesive system in non-carious cervical lesions: A randomized, controlled 24-month clinical trial.

Purpose: This randomized, controlled study evaluated the 2-year clinical performance of two flowable resin composites performed with a universal adhesive in two etching modes for restoring non-carious cervical lesions (NCCLs).

Methods: One hundred NCCLs were restored with two flowable composites ( Charisma Opal Flow and G-aenial Universal Flo) and a universal adhesive (Single Bond Universal) with two etching modes (self-etch and etch&rinse) in a random order. The restorations were evaluated for retention, marginal adaptation, anatomic form, marginal discoloration, surface texture and secondary caries (modified USPHS criteria) at baseline, and after 6, 12 and 24 months.

The improvement of biocompatibility of adhesives : The effects of resveratrol on biocompatibility and dentin micro-tensile bond strengths of self-etch adhesives.

Objective: The aim of this in vitro study is to evaluate the effects of resveratrol (RES) addition on the cytotoxicity and microtensile bond strength (μTBS) of different adhesives.

Materials And Methods: Five self-etching adhesives (G-aenial Bond-GC, Optibond All in One-Kerr, Gluma Self Etch-Kulzer, Clearfil S Bond-Kuraray, and Nova Compo-B Plus-Imicryl) were tested. They were applied to L-929 cell culture by the extract method.

The protective effect of resveratrol against dentin bonding agents-induced cytotoxicity.

This study was designed to evaluate the cytotoxicity of four dentin bonding agents and the effects of an antioxidant addition. Group A: G-aenial Bond, Group B: Optibond All in One, Group C: Gluma Self Etch and Group D: Clearfil S(3) Bond were added to the medium using extract method. The cells were cultured with or without resveratrol (RES) addition.
