In Vitro Analysis of Quality of Dental Adhesive Bond Systems Applied in Various Conditions

Abstract

Introduction: There are several methods of reducing a microleakage, and one of them is choosing appropriate adhesive material. The aim of the work was the in vitro analysis of 4 bonds: 3M ESPE “Single bond”, Dentsply “Prime and Bond Active”, Coltene “One Coat 7 Universal”, and Kuraray “Clearfil Universal Bond Quick”. Material and methods: 136 healthy molar teeth were collected and randomly split into 4 groups and Vth Class cavities were prepared. Chosen adhesives were used in four groups of teeth with the same composite. Teeth were the thermocycled, sealed, covered with lacquer, and submerged in 1% methylene blue solution for 24 h. After the thermocycling, the vertices of each tooth were sealed using dental wax. Each tooth was then fully covered with lacquer. All teeth were then submerged into 1% methylene blue solution for 24 h in room temperature. In the next step they were transversely cut through a center of restoration. The Olympus BX43 microscope was used to photograph each cut tooth. With the usage of Olympus stream software, measurement of the dye’s leakage was performed. Results. The statistical analysis proved that the most effective material when applied to ideally prepared cavity surface was Dentsply “Prime and Bond Active”. The second material was 3M ESPE “Single Bond”, third—Coltene “One Coat 7 Universal” and fourth—Kuraray “Clearfil Universal Bond Quick”. The most effective material applied to a too-dry surface was Dentsply “Prime and Bond Active”, second—3M ESPE “Single Bond”, third—Coltene “One Coat 7 Universal” and fourth—Kuraray “Clearfil Universal Bond Quick”. When it comes to too damp surfaces the best results were obtained with Dentsply “Prime and Bond Active” then Coltene “One Coat 7 Universal”, 3M ESPE “Single Bond” and Kuraray “Clearfil Universal Bond Quick”. Conclusion: The level of cavity dampness influences the quality of adhesives. Better results are obtained with over-dried surfaces than over-damp, which is connected with the dilution of the material.

Assessment of Wettability and Contact Angle of Bonding Agent with Enamel Surface Etched by Five Commercially Available Etchants: An In Vitro Study

“…e wetting behavior of dentin bonding agents is influenced by the adhesive blend's physicochemical characteristics, which is influenced by the acid etchant in use. Similar results were obtained in a study performed by Trzcionka et al, which suggested that overdried surfaces exhibit bonding more strongly than overdamp surfaces due to dilution of material [21]. is forms the basis of double-step etching and priming procedures in orthodontic bonding.…”

Resin-Based Cement Applied to Enamel and Dentin Pre-Treated with Phytic Acid: An In Vitro Study

“…The clinical relevance, if any, of the different etching patterns is not well understood, however, they are essential for a better understanding of the fundamentals of adhesion [30]. In view of this, future studies should be directed toward in-depth analysis and comparison between these two acids in terms of their effects on the chemical and physical properties of enamel and the bonding quality including its effect on microleakage under different conditions that simulate clinical situations [40].…”

Bonding Performance of a Hydrophilic Amide Monomer Containing Adhesive to Occlusal and Cervical Dentin

“…Given the higher wettability of this monomer, the manufacturer insists that immediate air-drying after application of the adhesive should be performed. If done, it could be advantageous for good adhesion, especially in the cervical region, because the shorter manipulation time could avoid irritation from adhesion-reducing factors such as bleeding from the gingiva, gingival crevicular fluids, and moisture in the oral cavity, among others [11]. Furthermore, this 1-SEA can also be used for pretreatment in abutment construction using composite resin and the pretreatment of resin cements in the luting of prostheses [12].…”
