Comparative analysis of bond strength and microleakage of newer generation bonding agents to enamel and dentin: An in vitro study

Abstract

Aims: This study aims to evaluate the bond strength (BS) and microleakage (ML) of the newer bonding agents to enamel and dentin. Objective: (1) To analyze the BS between self-etch and total-etch adhesives. (2) To analyze the depth of ML between self-etch and total-etch adhesives. Materials and Methods: Sixty mandibular premolars were fabricated and randomly divided into three groups: Group I ( n = 20)-bonded with self-etch adhesive + nanohybrid, Group II ( n = 20) with total-etch adhesive + micro hybrid and Group III ( n = 20) with total-etch adhesive + nanocomposite. Teflon ring molds were used to make composite resin cylinders bonded to the buccal surface. Class II box cavity was prepared on the samples' proximal surface and condensed with composite resin with each group's specific bonding protocol. Shear BS and ML testing were conducted, and data analyzed. Statistical Analysis: Kruskal–Wallis analysis was done to statistically differentiate the BS and ML between the three experimental groups; the P < 0.05, it showed a statistically significant difference. Intergroup comparison was made using the Mann–Whitney U test. Conclusions: Within this study's limitation, resin bonded with self-etch G-Premio Bond used in selective etch technique showed the highest BS and resistance to ML.

Dental restorative materials and halitosis: a preliminary in-vitro study

“…It is crucial to acknowledge the role of metal ions, such as, silver, copper, and zinc, which exhibit antimicrobial effects against diverse oral bacteria [33]. These ions disrupt bacterial cell membranes, inhibit enzyme activity, and interfere with bacterial metabolism, ultimately diminishing bacterial viability and suppressing VSC production [34].…”

In-Vitro Evaluation of Dental Adhesive Bond Strength With Diode Laser Irradiation Before Photopolymerization

“…The findings of our study showed Adper Single Bond 2 in etch-and-rinse mode exhibited the highest shear bond strength to tooth dentin, irrespective of whether with or without diode laser irradiation prior to photopolymerization, compared to the use of Tetric N-Bond Universal, Prime, and Bond Universal self-etch adhesives. Hegde et al [ 14 ] study attributed having a separate step of acid etching of tooth dentin using 37% phosphoric acid (etch-and-rinse mode) to deeper penetration of subsequently placed dental adhesive into exposed collagen fibril scaffold with the formation of thicker, longer resin tags compared to self-etch adhesives with shorter resin tag formation, residual acidity, and hydrolytic instability, resulting in poor SBS to tooth dentin.…”

Time-Dependent Change of Color and Translucency of Recent Restorative Materials in Various Beverages

“…Glass ionomer cements (GIC), which are routinely used as tooth-colored restorative materials. GICs can be considered as the first-choice materials, especially in the restorations of patients with high cariogenic activity, due to their fluoride release feature that gives them a cariostatic property (4,5). In addition, current restorative materials are being developed by combining the strength and esthetics of composites with the benefits of glass ionomers.…”
