Objective: To evaluate the clinical efficacy of two flowable composite resins used to restore occlusal caries lesions. Tetric Flow (Vivadent) and Esthet-X Flow (Dentsply/Caulk) are composite resins with decreased filler loading (Tetric Flow: 67% filler by weight, 43% by volume; Esthet-X Flow: 61% filler by weight, 53% by volume) and lower viscosity compared to conventional composite resins.
Method And Materials: Sixty-three teeth with occlusal caries were randomly assigned to calibrated practitioners who placed occlusal restorations (32 for Esthet-X Flow; 31 for Tetric Flow).
Objectives: This double-blind study examined the bleaching effectiveness of two 30% carbamide peroxide bleaching gels: one with 5% potassium nitrate (treatment A) and one without (treatment B). The treatment time was reduced for this pilot study to one hour per day for 10 days to determine whether the higher concentration would whiten teeth and to ascertain the tooth sensitivity and gingival effects of the 30% solution.
Method And Materials: Forty subjects were selected with an initial tooth shade corresponding to Bioform shade guide B65 or darker.
Article Synopsis
- The study aimed to assess the effectiveness of two flowable resin composites, Tetric Flow and Esthet-X Flow, in restoring tooth decay in occlusal lesions, focusing on their lower viscosity compared to traditional composites.
- Sixty restorations were placed and evaluated over one year for factors like color match, marginal discoloration, and adaptation, showing Esthet-X Flow had a slightly better color match but no significant differences overall.
- Despite some deterioration in marginal quality over time, all restorations remained clinically acceptable at the one-year mark, leading to the recommendation that flowable resin composites should only be used for smaller restorations.
This study evaluated the clinical performance of a posterior resin composite used with a fourth- and fifth-generation bonding agent. Sixty-two Class I and II restorations were placed with half the restorations restored with Gluma Solid Bond (a fourth-generation bonding system, or total etch two-step system) and the other half restored with Gluma Comfort Bond and Desensitizer (a fifth-generation bonding system, or total etch one-step system). Solitaire 2 was used as the restorative material for all restorations.

F2000 and Silux Plus were used to restore the teeth with moderate-sized non-carious cervical lesions. F2000 was placed using two different bonding agents: F2000 self-etching primer/adhesive (F2000SE group) and Single Bond (F2000SB group); Silux Plus was placed as a control using Single Bond (SiluxSB group).

Methods: The tested materials were used to restore moderate-size Class 5 non-carious cervical lesions. All materials were used following the manufacturers' directions for etching, bonding, curing, and finishing.
