Evaluation of the Efficacy and Color Stability of Two Different At-Home Bleaching Systems on Teeth of Different Shades: A Randomized Controlled Clinical Trial.

Objective: This randomized controlled clinical trial compared the bleaching efficacy of two different at-home bleaching systems on teeth of different shades and their color stability after a 6-month follow-up.

Materials And Methods: Ninety-two patients (777 teeth) were randomly divided into three groups: (a) negative control, (b) patients treated with a custom-made tray containing 10% carbamide peroxide (10% CP/PF) (Opalescence PF), and (c) patients treated with a pre-loaded tray containing 6% hydrogen peroxide (6% HP/Go) (Opalescence Go). Teeth in all groups were divided into three sub-groups according to the VITA Classic Shade Guide: light (A1-C1), medium dark (C2-B3), and dark (A3.

Six-month Clinical Evaluation of a Self-adhesive Flowable Composite in Noncarious Cervical Lesions.

Purpose: The aim of this randomized, controlled, single-center, split-mouth clinical trial was to evaluate the clinical performance of a self-adhesive flowable composite resin (SAFC) in noncarious cervical lesions in comparison with a nanohybrid composite applied with a three-step etch-and-rinse adhesive system (E&Ra/nanoC).

Materials And Methods: Eighty noncarious cervical lesions were included and assigned to one of two groups according to the split-mouth design. The cervical lesions in the experimental group were restored with an SAFC (Fusio Liquid Dentin), while a nanohybrid composite (G-aenial) applied with a three-step etch-and-rinse adhesive system (Optibond FL) was used for the control group.
