    Evaluation of the Bond Strength of Different Pulp Capping Materials to Dental Adhesive Systems: An In Vitro Study
    (Sage Publications India Pvt Ltd, 2021) Akbiyik, Sema Yazici; Bakir, Elif Pinar; Bakir, Seyhmus
    Aim: To evaluate the bond strengths of pulp capping materials (Dycal, ProRoot MTA, Biodentine, TheraCal LC, Calcimol LC, and ApaCal ART) and different adhesive systems (Gluma 2 Bond, Clearfil SE Protect, Gluma Self Etch, Clearfil S-3 Bond Plus, Gluma Bond Universal, Clearfil S-3 Bond Universal). Materials and Methods: Two hundred fifty-two acrylic blocks were prepared in which cylindrical cavities of 4 x 2 mm(3) were formed. Pulp capping materials were placed in the cavities. Different adhesive systems were applied to each pulp capping material group. After applying the composite resin, the shear bond strength (SBS) values of the specimens were determined in the Instron test device. Fracture types were evaluated using a stereomicroscope and a scanning electron microscope. Data were analyzed by Shapiro-Wilk's and Kruskal-Wallis H test. Results: There is a statistically significant difference between pulp capping materials in terms of SBS values (P < .05). Dycal's SBS was found significantly lower than other materials, and the highest bond strength was observed in Calcimol LC material. Although there is no statistically significant difference (P > .05) between the adhesive agent groups in terms of SBS, Gluma 2 Bond showed the highest bond strength value. Conclusion: In traditional pulp capping materials such as Dycal, MTA, and Biodentine, using a two-step self-etch adhesive system can result in higher bond strength values. In resin-based TheraCal LC,, ApaCal ART, and Calcimol LC materials, it may be recommended to use a two-step etch and rinse adhesive system.

    Evaluation of the Bond Strength of Resin-Modified Glass Ionomer Enhanced with Bioactive Glass to Composite Resin with Different Dental Adhesive Systems
    (Sci Printers & Publ Inc, 2021) Bakir, Seyhmus; Bakir, Elif Pinar; Akbiyik, Sema Yazici
    OBJECTIVE: To investigate the bond strength of resin-modified glass ionomer enhanced with bioactive glass (Activa BioActive-Base/Liner) to composite resin using different dental adhesive systems. STUDY DESIGN: In this study, Activa BioActive-Base/Liner (ABA/BL) was placed in cylindrical cavities formed in acrylic blocks. In blocks divided into 6 groups according to the adhesive system to be applied, two-step etch-and-rinse Gluma 2 Bond (Heraeus Kulzer, Germany), one-step self-etch Gluma Self Etch (Heraeus Kulzer), universal system Gluma Universal (Heraeus Kulzer), two-step self-etch Clearfil SE Protect (Kuraray, Japan), one-step self-etch Clearfil S-3 Bond Plus (Kuraray), and universal system Clearfil S-3 Bond Universal (Kuraray) adhesive systems were applied on ABA/BL. After composite resin (3M ESPE Filtek Ultimate) was applied to the prepared surfaces, the specimens were placed in a universal test device and shear bond strength test was determined. Fracture types were evaluated using a stereomicroscope and scanning electron microscope. Data were analyzed by Shapiro-Wilk, two-way ANOVA, Kruskal-Wallis, and Post-Hoc Multiple Comparisons tests. RESULTS: In terms of bond strength values, the highest bond value was seen in the two-step self-etch (Clearfil SE Protect) group, and the lowest bond strength value was seen in the universal system (Clearfil S-3 Bond Universal) group. There was no statistically significant difference between the adhesive agent groups in terms of bond strength values (p>0.05). CONCLUSION: It is thought that choosing the two-step self-etch technique as an adhesive system when resin-modified glass ionomer enhanced with bioactive glass (ABA/BL) is used as the pulp capping/base material will be more appropriate in terms of bond strength.
