Comparison of shear bond strength of composite resin to enamel surface with laser etching versus acid etching: An in vitro evaluation

A new cyanoacrylate adhesive developed for orthodontic use was subjected to a controlled in vitro trial of ultimate shear bond strength. Performance deteriorated on storage in saline, rendering the material unsuitable for clinical use. Other alternatives to conventional acid-etch retained composite resin bonding agents are discussed.

Group I

The aim of this study was to evaluate the shear bond strength of a composite resin to dental enamel, using three different surface treatments. Fifteen sound third molars were randomly assigned to three groups. The mesial and distal surfaces were flattened and covered using adhesive tape with a central orifice delimiting the adhesion area (7.07 mm²). Group I, the enamel surface was conditioned with 37% phosphoric acid for 15 s; group II, the surface was treated using air abrasion with aluminum oxide; group III, the enamel surface was treated using an association of air abrasion with aluminum oxide and 37% phosphoric acid. The Single Bond (3M) adhesive system was applied and a Teflon matrix was placed and filled with composite resin Z-100 (3M) and light-cured. The shear bond strength test was performed with a universal testing machine. The acid etching technique and air abrasion with aluminum oxide associated with acid etching had the highest shear bond strength values. Data were subjected to statistical analysis using ANOVA and the Tukey test, and no statistically significant difference in shear bond strength was observed between group I (12.49 ± 2.85 MPa) and group III (12.59 ± 2.68 MPa). In contrast, both groups had statistically better shear bond strengths compared to group II (0.29 ± 0.56 MPa; p<0.05). Air abrasion with aluminum oxide does not substitute acid etching. The association of these methods to obtain adequate adhesion to the substrate is necessary.

ABSTRACT To produce good adhesion between composite resin and etched enamel surface, it is necessary to form a microscopi- cally intimate contact between them. Contaminants, like saliva, may interfere with such bonding. Salivary contamination may reduce the bond strength between composite resin and the enamel by 40 to 60%. Recent studies have suggested that only rewashing and drying of the etched and saliva contaminated enamel surface is sufficient in restoring bond strength to the normal ideal condition. Purpose To evaluate the effect of saliva contamination on the shear bond strength of composite resin to enamel by using different parameters. Materials and methods The highest mean shear bond strength of composite resin was obtained on the uncontami- nated enamel surface, and the lowest mean shear bond strength was obtained on the saliva contaminated moist enamel surface. Results The mean shear bond strength of composite resin to saliva contaminated, washed and air-dried enamel surface was less than the mean shear bond strength to the dry enamel surface. Conclusion This suggests that only rewashing of the saliva contaminated enamel surface is not enough in achieving bond strength equal to that of the uncontaminated enamel surface.

Objective: This study was undertaken to assess the effect of enamel deproteinization with 5.25% sodium hypochlorite (NaOCl) before phosphoric acid (H3PO4) etching on the shear bond strength of Adper™ Single Bond 2 adhesive and Filtek™ Z- 350 XT composite resin . Study design: Forty human sound permanent molars which were extracted for periodontal reasons were used in the experimental protocol as under:Group-A (20 teeth):– A 5X4 mm window of the enamel surface was etched with 37% H3PO4 gel for 15 seconds,washed with distilled water and air dried. A single coat of Adper™ Single Bond 2 adhesive was applied and photo polymerized for 20 seconds and Filtek™ Z- 350 XT composite resin block of length 5mm,width 4mm and height 5mm respectively was built and photo polymerized in increments for 20 seconds each. Group-B (20 teeth):- Similarly the enamel surface was treated with 5.25% NaOCl for 60 seconds, washed with distilled water and then etched with 37% H3PO4 gel for 15 seconds, washed with distilled water and air dried. A single coat of Adper™ Single Bond 2 adhesive was applied and photo polymerized for 20 seconds and Filtek™ Z- 350 XT composite resin block of length 5mm, width 4mm and height 5mm respectively was built and photo polymerized in increments for 20 seconds each. The shear bond strength of all the samples were measured (in MPa) on Instron Mechanical Testing Machine. Results: The mean shear bond strength value for Group-A was 13.51 ± 5.726 MPa and for Group-B being 15.06 ± 6.220 MPa. No statistically significant difference in the shear bond strengths was observed between the two groups. Conclusions:No significant effect of sodium hypochlorite enamel deproteinization on the shear bond strength of Adper™ Single Bond 2 adhesive and Filtek™ Z- 350 XT composite resin before acid etching was observed in this study.
