title: Deproteinization treatment on bond strengths of primary, mature and immature permanent tooth enamel.
abstract: OBJECTIVE
  The aim of this study was to examine the effect of pre-post deproteinization treatment with 5% sodium hypochloride on shear bond strength (sbs) of adhesive resin to primary, immature and mature permanent teeth enamel.
  
  
  METHODS
  30 teeth were used for each of primary, immature and mature permanent teeth groups. (totally 90). In control groups, enamel was etched for 60s with 37% phosphoric acid (3M) and rinsed for 10s (Procedure A). In experimental groups, deproteinization was applied with 5% NaOCI solution for 120s before (Procedure D+A) and after acid-etching (Procedure A+D). Gluma Comfort Bond (Heraeus-Kulzer) and Charisma (Heraeus-Kulzer) composite resin were applied to etched enamel surfaces. Data were determined with Two-Way ANOVA and LSD Multiple Comparison Test (p < 0.05).
  
  
  RESULTS
  SBS was significantly lower in primary and immature permanent teeth than mature permanent teeth (p < 0.05). "Procedure A+D" statistically increased sbs values in primary and immature permanent teeth (p < 0.05).
  
  
  CONCLUSIONS
  Deproteinization after acid etching significantly enhanced the shear bond strength values in primary and immature permanent teeth.
