Background:The latest advancement in adhesive dentistry is the development of self adhering flowable composite resin which incorporates the self-etch adhesion technology to eliminate the steps of etching, rinsing, priming and bonding. Few studies have addressed resin bonding to primary teeth.Aim:The aim of this study was to compare the shear bond strength and nanoleakage of conventional and self adhering flowable composites to primary teeth dentin.Settings and Design:This study was conducted in the Department of Pedodontics and Preventive Dentistry, I.T.S Dental College, Hospital and Research Centre, Greater Noida; in association with the Department of Mechanical Engineering, I.T.S Engineering College, Greater Noida; and the Advanced Instrumentation Research Facility (AIRF), Jawaharlal Nehru University, New Delhi.Materials and Methods:Sixty of the ninety primary teeth were evaluated for shear bond strength and thirty for nanoleakage. The samples were divided into three groups; Group I – Dyad Flow (Kerr), Group II – Fusio Liquid Dentin (Pentron Clinical Technologies) and Group III – G-aenial Universal Flo (GC). Shear bond strength was determined using a universal testing machine. Nanoleakage pattern was observed under scanning electron microscope.Results:The shear bond strength of conventional flowable composite was significantly greater than self adhering flowable composite (p<0.05). Nanoleakage scores of both conventional and self adhering flowable composites were comparable.Conclusions:Self adhering flowable composites combine properties of composites and self etch adhesives, eliminating the need for separate bond application that simplifies direct restorative procedure. The evolution of self adhering materials could open new horizons for pediatric dentistry.

The aim of this study was to determine the effect of three storage solutions and two storage durations on microshear bond strength (μSBS) of a resin composite. Sixty non-carious human permanent molars were stored in three storage solutions (0.1％ thymol, 10％ formalin, and distilled water). Each tooth was separated mesio-distally into two parts. Specimens of the first part were stored for 24 hours, while specimens of the second part were stored for two months in the solutions. After each storage period, the enamel surface was covered with a composite resin in combination with an etch-rinse adhesive system. Specimens were then serially sectioned into sticks of 1 mm 2 bond area and subjected to μSBS test. There were no statistically significant differences between the two storage periods for each solution (p>0.05). The thymol solution group showed lower μSBS values than those of distilled water for both storage periods (p<0.05). As for the formalin group, its μSBS values were not statistically different from those of distilled water and thymol groups at each storage period (p>0.05).In conclusion, the thymol solution caused the μSBS of the resin composite to decrease when compared to both formalin and distilled water after 24 hours and two months. However, the μSBS of the resin composite was not affected by storage duration.

“…26,27 The results found for the etch-and-rinse adhesives showed that its bonding to enamel was not affected by the presence of water, which agrees with the findings of previous studies. 11,28 The bonding solution present in Scotchbond contains bisphenol A diglycidyl methacrylate (Bis-GMA) and 2-hydrox- yethyl methacrylate (HEMA), combined with an initiation system. The presence of HEMA gives this material a hydrophilic behavior, which explains why the water had little influence on the bond strength when the adhesive was applied without the primer solution.…”

“…Bond strength may be reduced if the tooth is contaminated with saliva during adhesive procedures. 9 However, the influence of water after enamel etching and before application of the adhesive has not been thoroughly defined, 10,11 especially in relation to self-etching adhesives. With selfetching adhesives, the composition includes not only hydrophilic monomers but also water and organic solvents such as acetone and ethanol.…”

The enamel surface should not be desiccated extensively when an all-in-one self-etching adhesive is employed. SUMMARYObjective: To evaluate, through the application of different dentin bonding systems, the influence of wetness on shear bond strength in enamel.Methods: This study evaluated three etch-andrinse adhesive systems (Scotchbond MP [used with and without primer]; Singlebond; and Prime&Bond 2.1) and two self-etching adhesive systems (Clearfil SE Bond; and Xeno IV). Flat bovine enamel surfaces were either airdried for 30 seconds or blotted with absorbent paper after acid-etching for the conventional bonding agents or before the application of self-etching bonding agents. The resin composite EsthetX was bonded to flat surfaces that had been treated with one of the adhesives, following the manufacturer's instructions. After being stored in water at 378C for one week, bonded specimens were broken in shear. Data were evaluated with two-way analysis of variance (ANOVA) and Student-Newman-Keuls tests (a¼0.05). For comparing each condition , 2011, 36-3, 274-280 individually, regardless of the adhesive or wetness condition, a one-way ANOVA and a Student-Newman-Keuls test (a¼0.05) were applied.Results: The two-way ANOVA showed significant differences among adhesive systems. An interaction effect was also observed (p,0.05), but wetness did not influence shear bond strength (p¼0.98). The one-way ANOVA showed that the all-in-one adhesive was the only material influenced by the presence of water at the enamel's surface.Conclusion: The all-in-one adhesive behaved differently depending on whether the enamel surface was dry or wet.
