Abstract

Thirty sound human upper premolars were used to evaluate the in vitro effect of collagen removal from the acid-etched dentin surface on the penetration depth of three types of dental adhesive systems. Standardised buccal and lingual class V cavities were made and the teeth were then subdivided randomly into six groups five teeth each. Three types of dental adhesive systems were used (syntac sprint, Vivadent-Liechtenstein. Syntac single component, Vivadent-Liechtenstein. PQ1> Ultra Dent-USA). The bonds were used with and without deproteinization (10% Sodium hypochlorite for one minute). The highest mean of penetration depth (10.15 jl) was recorded in the group where the PQ1 bond was used on acid-etched and NaOCl-treated dentin. The lowest mean of penetration depth (5.77jl) was recorded where the Syntac Single Component bond was used on the acid-etched dentin surface.

Conclusion: A one minute application of 10% sodium hypochlorite on conditioned dentin significantly increases the penetration depth regardless of the type of adhesive system used. Alcohol-containing systems showed the greatest penetration.
