“…The majority of previously published reports have focused on the influence of saliva on orthodontic adhesives [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] or fissure sealants, [19][20][21][22][23] and only a few reports have dealt with the effect of salivary contamination on resin restorations. 24 Controversial data have been reported regarding the effect of saliva contamination on the enamel bond strength of adhesives, because it depends not only on the individual adhesive used, but also on the adhesive in combination with the primer.…”

SUMMARYObjective: This study evaluated the effect of saliva contamination on the bovine enamel microtensile bond strengths (µTBS) of four selfetching adhesives. Materials and Methods: The labial enamel surfaces of extracted non-carious bovine incisors were serially wet ground. The enamel surfaces were not contaminated (Group A), contaminated with saliva before/after priming (Groups B/C) or they were water-sprayed after salivary contamination occurred before/ after priming (Groups D/E). Four self-etching adhesives and the corresponding resin composites from the same manufacturer (Clearfil SE Bond + Clearfil AP-X, Kuraray Co; Xeno III + Ceram X, Densply; Frog + Ice, SDI; FL Bond II + Beautifil II, Shofu Inc) were applied onto the enamel surfaces. The µTBS tests were performed with a micro tester (BISCO, Inc). The enamel surface was analyzed with AFM (Atomic Force Microscopy) before/after salivary contamination occurred or after the saliva-contaminated enamel was water-sprayed. The data were analyzed using one-way ANOVA, factorial design ANOVA and post hoc Tukey's HSD multiple comparisons. Salivary contamination before and after priming could significantly reduce the enamel bond strength of self-etching adhesives. Proper isolation should be performed before and during application of the adhesives and placement of the resin composite. Thorough water-spraying could significantly improve the µTBS of saliva-contaminated enamel.

“…However, when using bonding brackets or an eruption appliance on partially erupted or impacted teeth, procedures such as protective liquid polishing must be applied before contamination occurs to prevent negative effects on bond strength. (Sayınsu & Işık, 2007) The presence of prismatic and aprismatic enamel affects the efficacy of phosphoric acid. While a more uniform surface appearance is achieved by etching in the presence of prismatic enamel, bond strength is reduced in the presence of aprismatic enamel.…”

“…However, clinical conditions during the act of surgery do not allow ideal isolation of the bonding site, and may cause failure of composites to bond to tooth enamel (CACCIAFESTA et al, 2003;OZTOPRAK et al, 2007;SAYINSU et al, 2007). The properties of a composite may be harmed by various intraoral factors, which include a high degree of humidity inside the oral cavity, aging of the tooth, dental caries, saliva and/or blood at the bonding site (CACCIAFESTA et al, 2004ab).…”

“…However, momentary contamination of the bond areas by blood forms an organic pellicle that diminishes enamel porosity, reducing the micro retention creation, and thus making it difficult for composites to adhere (OONSOMBAT et al, 2003;OZTOPRAK et al, 2007;SAYINSU et al, 2007;CAMPOY et al, 2010).…”

ABSTRACT:This study aimed to evaluate the best method for decontaminating tooth enamel contaminated with blood/saliva before bonding orthodontic accessories, since such contamination is commonly present in surgical procedures of extrusion/orthodontics. 195 bovine incisors were used. Initially their vestibular faces received prophylaxis, H3PO4 at 37% and adhesive application. After this, the vestibular faces of all the teeth were contaminated with blood/saliva. The teeth were then randomly divided into 13 groups (n=15), Group C (Control -without contamination and bonded according to manufacturer's recommendations) and 12 experimental groups according to the decontamination method: Group WD-without decontamination, Group DW-washed with distilled water, Group PS-washed with physiologic solution, Group JA-jets of air, Group G-gauze, Group CW-cotton wool, Group DW+JA-distilled water + jets of air, Group DW+G-distilled water + gauze, Group DW+CW-distilled water + cotton wool, Group PS+JA-physiologic solution + jets of air, Group PS+G-physiologic solution + gauze, Group PS+CW-physiologic solution + cotton wool. After bonding the shear bond strength test was performed on all the samples at a speed of 0.5mm/min. Data were analyzed statistically by ANOVA and Tukey's test at 5% significance level. The results demonstrated absence of statistical differences between the Control and Groups DW+JA and PS+JA (P>0.05). The groups that presented the lowest bond strength values were Group WD, in which no decontamination was performed, and Group PS in which specimens were washed with physiologic solution only. The best methods of decontaminating enamel contaminated with blood/saliva were washing with distilled water or physiologic solution followed by drying with jets of air.
