“…The present study found no difference in bond strength between the two application modes. This finding not only corroborates the claims of the manufacturer, improving clinical versatility, but it is also in harmony with the results of previous studies [18–20]. The phosphoric acid applied according to the “total-etch” mode results in removal of the smear layer and smear plugs and in opening of the dentin tubules (Fig 2).…”

PurposeTo compare various pre-treatments serving as cleaning procedures of dentin on the bond strength of resin composite promoted by a universal adhesive system applied either in the absence or presence of simulated pulpal pressure.Materials and MethodsPrior to application of the adhesive system (Scotchbond Universal) and resin composite (Filtek Z250), ground dentin surfaces were given one of five pre-treatments either without or with simulated pulpal pressure: 1) no pre-treatment, adhesive system in “self-etch” mode, 2) phosphoric acid etching, adhesive system in “total-etch” mode, 3) polishing with pumice on prophylaxis cup, 4) air abrasion with AIR-FLOW PLUS powder, 5) air abrasion with AIR-FLOW PERIO powder; n = 20/group of pre-treatment. After storage (37°C, 100% humidity, 24 h), micro shear bond strength was measured and data analyzed with parametric ANOVA including Bonferroni-Holm correction for multiple testing followed by Student’s t tests (significance level: α = 0.05).ResultsThe ANOVA found type of pre-treatment and simulated pulpal pressure to have no significant effect on dentin bond strength. The explorative post-hoc tests showed a negative effect of simulated pulpal pressure for phosphoric acid etching (adhesive system in “total-etch” mode; p = 0.020), but not for the other four pre-treatments (all p = 1.000).ConclusionAir abrasion with powders containing either erythritol and chlorhexidine (AIR-FLOW PLUS) or glycine (AIR-FLOW PERIO) yielded dentin bond strengths similar to no pre-treatment, phosphoric acid etching, or polishing with pumice. Simulated pulpal pressure reduced the bond strength only when the self-etch adhesive system was used in total-etch mode.

“…However, over-etching of the underlying mineralized dentin may occur; thus, resin monomers would not penetrate the full depth of the demineralized dentin, producing a porous, non-resinous, infiltrated zone (19). The universal adhesives showed equivalent bonding quality to that of dentin regardless of etching mode (20). In AI enamel, this adhesive system without previous etching provided a bond strength similar to that of etch-and-rinse adhesive systems (21).…”

“…The use of a universal adhesive eliminated the etch, rinse and dry phases, and showed relevant results in terms of bond strength (20,21), thereby obliterating the dentin tubules, and reducing or eliminating tooth sensitivity (11,14). Thus, based on the present clinical case, it may be concluded that the sealing of the exposed dentin on teeth affected by AI by a universal self-etch adhesive system effectively reduced or eliminated tooth sensitivity immediately and maintained this effect during the 12-month follow-up period.…”

Immediate Desensitization in Teeth Affected by Amelogenesis Imperfecta

et al. 2016

The aim of this paper was to describe a clinical case of immediate dental desensitization using a self-etch adhesive system in an adolescent patient diagnosed with amelogenesis imperfecta (AI). AI was associated with severe tooth sensitivity, treated by the application of a universal adhesive system for desensitization of the teeth affected by AI. Reduction of tooth sensitivity was assessed using a visual analog scale during all reevaluations. The technique was effective for reducing tooth sensitivity. It was concluded that the adhesive system for tooth desensitization had an immediate effect and maintained its effectiveness during a 12-month follow-up period.

“…Highly effective bonding performance of universal adhesives reflects chemical bonding capacity of functional monomers to various substrates [17][18][19][20] . Moreover, the extent to which liquid drops wet dentin surfaces depends on chemical interactions between the liquid and dentin, and on physical considerations such as capillary action, and surface roughness 21) .…”

(AB, Bisco) were used in this study. Bovine dentin surfaces were air polished with glycine or sodium bicarbonate powders prior to the bonding procedure, and resin pastes were bonded to the dentin surface using universal adhesives. SBSs were determined after 24-h storage in distilled water at 37°C. Surface-free energy was then determined by measuring contact angles using three test liquids on dentin surfaces. Significantly lower SBSs were observed for dentin that was air-powder polished and surface-free energies were concomitantly lowered. This study indicated that air-powder polishing influences SBSs and surface-free energies. However, glycine powder produced smaller changes in these surface parameters than sodium bicarbonate.
