Background: This study evaluated the effect of nano-silica (NS) incorporation with resin infiltrant on water sorption and solubility of resin infiltrant, mineral density of demineralized enamel, and resin tags penetration.
Methods: NS (Sigma-Aldrich, St Louis, Missouri, USA) was added into the resin infiltrant (ICON, DMG, Hamburg, Germany) at two concentrations by weight. The tested groups were: ICON (control), ICON + 0.
Objectives: To evaluate surface microhardness and gingival marginal adaptation of three different bulk-fill flowable resin composites (FB-RBCs) in Class V cavities with enamel or dentin margins before and after thermocycling (TMC).
Materials And Methods: Three available FB-RBCs were used; Palfique Bulk Flow (PaBF) (Tokuyama Dental), SDR Flow+ Bulk Fill Flowable (Dentsply Sirona), and I-Flow Bulk Fill (I-Dental). Thirty discs were prepared from each type of FB-RBCs.

Aim: To compare the color change of three flowable composites after exposure to staining solutions.
Materials And Methods: A total of 240 oval samples were constructed of conventional flowable resin composite, self-adhesive flowable resin composite, and nanohybrid flowable ormocer ( = 80). Each set was further subcategorized into three subsets as regards staining solution.
Aim: The present randomized clinical study compared the 18 months performance of self-adhering flowable composite with a conventional flowable composite in anterior Class V restorations.
Materials And Methods: Totally, 20 patients, each with two moderate cervical carious lesions, participated in this single-center study. Forty restorations were allocated on a random basis by one examiner not involved in the restoration or the evaluation procedures, In each patient, one lesion was allocated to be restored using self-adhering flowable composite [Fusio liquid dentin (FL)] and the other to be restored using conventional flowable composite [Tetric Flow (FF)].
Aim: The aim of the study is to evaluate the effectiveness of two different in-office bleaching agents, Zoom2 (Z) and Boost (B), regarding color stability 1-week, 2-week, 1-month and 2-month periods after treatment.
Materials And Methods: A total of 60 patients each of whom had anterior teeth of shade A3 or darker were randomly selected from the pool of patients attending the Dental Hospital at the University of Dammam. For the Z group (n = 30), a light activation unit was used to activate the bleaching agent.
Objectives: We aimed to evaluate the potential cytotoxicity (apoptosis-induction) of three types of self-etch dental adhesives: two-component one-step (Xeno III), two-component two-steps (Clearfil Protect Bond) and one-component one-step (Xeno V) on cultured odontoblasts.
Methods: Each adhesive was prepared to simulate its clinical manipulation. Cured sterile individual masses were immersed in DMEM and left at 37 °C for 24 h.
Purpose: To evaluate and compare the 2-year clinical performance of an ormocer, a nanohybrid, and a nanofill resin composite with that of a microhybrid composite in restorations of small occlusal cavities made in posterior teeth.
Materials And Methods: Thirty-five patients, each with 4 occlusal restorations under occlusion, were enrolled in this study. A total of 140 restorations was placed, 25% for each material: an ormocer-based composite, Admira; a nanohybrid resin composite, Tetric EvoCeram; a nanofill resin composite, Filtek Supreme; and a microhybrid resin composite, Tetric Ceram.
