Official Title: Randomized Controlled Trial of Self-etching Adhesive Systems on Caries-affected Dentin: Microbiological Evaluation and Clinical 24-month Follow-up
Brief Summary: The objectives were to evaluate the antibacterial effect of self-etching adhesives on carious dentin and the clinical results of restorations in a randomized controlled clinical trial. 104 carious deciduous molars (n=92) were randomly allocated to receive one of the self-etching adhesives: Clearfil SE Bond - control (CB - n =53) or Clearfil SE Protect containing MDPB (CP - n=51) after caries removal selective. Clinical, radiographic, photographic and plaster model assessments (n=53 deciduous molars, CB=29, CP=24) of resin restorations were performed at baseline and at 6, 12, and 24 months. Dentin samples (n=51 deciduous teeth; CB=24 and CP=27) were collected immediately after excavation of carious dentin and 3 months later, and cultured for mutans streptococci - (MS), lactobacilli (LB) and total microorganisms (TM). Data were statistically analyzed (p<0.05).
