Dentinal tubule anastomosis: A potential factor in adhesive bonding?

摘要: This study investigated adhesive tag formation within dentinal tubules and the anastomosing of lateral canals observable with scanning electron microscopy. mechanism micromechanical bonding had not been studied previously. The following brands adhesives were applied to prepared dentin surface unerupted human third molars: Scotchbond Multipurpose, C&B Metabond, All-Bond 2, both etched unetched, Tenure Solution, XR-Bond. experimental specimens decalcified for SEM examination. Many tubule resin tags branching observed. branches result primer, adhesive, or entering communicating adjacent tubules. polymerization in was more prevalent C & B 2 adhesives. network interconnected formed these materials may be fundamental development a stronger dentin/resin bond.
