Clinical behavior of universal adhesives in non-carious cervical lesions: A randomized clinical trial.

Objectives: This randomized, double-blind clinical trial, , evaluated the behavior of two universal adhesives used in etch-and-rinse (ER) or self-etch (SE) approach in non-carious cervical lesions (NCCLs).

Methods: Two hundred and eleven NCCLs were selected in 54 participants and randomly allocated into four experimental groups: Scotchbond Universal Adhesive - SBU (3M Oral Care) and Prime & Bond Elect - PB (Dentsply Sirona) used in ER and SE modes. Two trained operators placed all resin composite restorations (Filtek Z250, 3M Oral Care).

Self-etch Approach of Universal Adhesives as an Alternative to Minimize Bond Degradation on Sound Dentin vs Caries-affected Dentin over Time.

Purpose: To investigate the influence of the etching strategy of universal adhesives on bond degradation to sound and artificially-induced caries-affected dentin.

Materials And Methods: The universal adhesives (Scotchbond Universal Adhesive; All-Bond Universal; Prime&Bond Elect) and adhesives used as controls (Adper Single Bond 2 and Clearfil SE Bond) were applied to sound and artificially-induced caries-affected bovine dentin. Microtensile bond strength was evaluated immediately (24 h) and after one year of water storage (1 year).

Phosphoric Acid Containing Chlorhexidine Compromises Bonding of Universal Adhesive.

Purpose: To examine the influence of phosphoric acid containing chlorhexidine on the dentin bond stability of a universal and a 2-step etch-and-rinse adhesive.

Materials And Methods: Eighty sound bovine incisors were randomly assigned to 8 groups (n = 10) according to: phosphoric acid (37% phosphoric acid [CTR] or 37% phosphoric acid with 2% chlorhexidine [CHX]); adhesive (Scotchbond Universal Adhesive [SBU]or Adper Single Bond 2 [SB2]); and water storage time (24 h and 6 months). Both acids and adhesives were applied to flat dentin surfaces (following manufacturer's instructions) upon which composite cylinders were built up (0.

Internal adjustments decrease the fatigue failure load of bonded simplified lithium disilicate restorations.

Objective: To investigate the effect of intaglio surface adjustment of simplified lithium disilicate ceramic restorations adhesively cemented to a dentin-like material on its fatigue behavior.

Methods: Ceramic discs (IPS e.max CAD) were prepared and an in-Lab simulation of machining roughness was performed by grinding with SiC paper (#60).

The impact of artificially caries-affected dentin on bond strength of multi-mode adhesives.

Aim: The aim of this study is to evaluate the impact of dentin condition on bond strength of multi-mode adhesive systems (MMAS) to sound and artificially induced caries-affected dentin (CAD).

Methods: Flat dentin surfaces of 112 bovine incisors were assigned to 16 subgroups ( = 7) according to the substrate condition (sound and CAD- pH-cycling for 14 days); adhesive systems (Scotchbond Universal, All-Bond Universal, Prime and Bond Elect, Adper Single Bond Plus and Clearfil SE Bond) and etching strategy (etch-and-rinse and self-etch). All systems were applied according to the manufacturer's instructions, and resin composite restorations were built.
