“…This chemical interaction between MDP and hydroxyapatite increase the mechanical strength of the adhesive interface in the self-etch strategy. (25) This agreement with Yoshida et al (26), Oznurhan et al in (16) whose found that with total-etch adhesive system the major elements that contribute to bond strength are intratubular resin-tag into demineralized intertubular dentine. This might be more difficult to happen in deep dentin because of the smaller amount of intertubular dentin to form the hybrid layer ,therefore deep dentin is more porous and retains more water within its enlarged tubule openings, which may avoid appropriate lateral bonding of the resin tags This disagreement with Ting et al (27) who reported that that the bond strength of one-step self-etch adhesive materials increased with increasing remaining dentin thickness (RDT), whereas that of two-step selfetch material was not affected by RDT.…”

Aim: to evaluate micro tensile bond strength of new generation composite resins with dentin. Methods: Extracted human premolars teeth (n=48)were used to preper one hundred and sixty eight sticks .Specimens divided into two equal main groups according to types of composite used (A1; Xtra fil bulk-fill and A2; Tetric-N-Ceram bulk-fill). Then each main group were subdivided according the adhesive approach used into two equal subgroups (B1; total each and B2; self-etch). According to dentin depths each subgroup were further categorized into two equal categories according to dentin depths (C1; superficial and C2; deep). The μ-tensile bond strength was evaluated using universal testing machine at a crosshead speed of 0.5 mm/min. until failure occurred. Data were recorded, tabulated and statistically analysed.. Results: showed significant (p<0.05) effect of composite and dentin level on μ-tensile bond strength, while the effect of adhesive showed non-significant (p>0.05) dentin.Conclusion: Xtra-Fill bulk-fill has higher bond strength than Tetric Bulk-fill. Additionally, Total-etch adhesive system has higher bond strength than self-etch with the superficial dentin while self-etch adhesive system has higher bond strength with the deep dentin

Buonocore introduced Adhesion into dentistry 1955. According to the preference of the practitioners, each generation of adhesive was replaced by the next generation which overcame the disadvantages of the previous generation. Now, the adhesive which is in use are Self Etch, Total etch Adhesives and Resin modified approach as it has unique properties of self adherence to the tooth. The concept of total etching or etch and rinse technique was given way back in the early 1980s by Fusayama. With this background, the aim of the present study is to survey the preference of Self etch VS Total etch among dental practitioners. A Cross-sectional survey was conducted among the dental practitioners about their preference for self-etch and total-etch adhesive. The data was collected and statistically analysed using the SPSS software version 23. Descriptive statistical analysis was carried out and the chi-square test was used and the p-value was calculated, with a p-value less than 0.05 to be statistically significant. The present survey included 209 dental practitioners of different categories with a clinical experience of at least 3 months, 32.69 % of the practitioners had clinical experience of 10 years and more than that. 71.15 % of the practitioners preferred the usage of Total Etch and remaining 28.85 % preferred the usage of self etch. According to the Practitioners, 68.75 % considered the total etching technique as the best technique and 31.25 % considered self etch as the beat technique. From this survey, it is seen that the majority of the practitioners preferred using total-etch compared to self etch. Despite having its disadvantage it is preferred by the practitioners.

“…SEM images showed that the adhesive failure was dominant in both enamel and dentin groups and among all the tested adhesive systems. In the study by Gre et al, [ 37 ] the microtensile bond strength of a total-etch adhesive and universal adhesives was analyzed and it was indicated that most of the fracture modes were adhesive in all techniques . Further studies are recommended to assess the long-term durability of universal adhesive systems.…”

Objectives: The aim of this study was to assess the microtensile bond strength of three universal adhesives to dentin and enamel. Materials and Methods: Sixty extracted human third molar teeth were chosen and divided into six groups regarding the adhesive (G-Premio Bond, Clearfil S3 Bond or Single Bond) and tooth surface. All the applied bonding agents were universal adhesives. The teeth were polished and the adhesives were applied; then the teeth were restored with composite resin. The samples were mounted in acrylic resin and sectioned. The specimens were subjected to a universal testing machine and the microtensile bond strength was measured. The failure mode of each specimen was determined under a stereomicroscope. Data were analyzed using two-way ANOVA (α=0.05). Results: The microtensile bond strength of G-Premio Bond to enamel and dentin was 11.79±8.27 and 17.55±9.47 MPa, respectively which was not significantly different from the values in Single Bond group (15.59±10.66 and 17.19±10.09 MPa to enamel and dentin, respectively; P>0.05). However, the values for Clearfil S3 Bond were 7.11±4.23 and 7.88±8.83 MPa to enamel and dentin, respectively, which were significantly lower than the values for G-Premio Bond (P<0.05). Scanning electron microscopic (SEM) images showed that the adhesive failure was dominant in both enamel and dentin groups and in all adhesive systems. Conclusion: G-Premio Bond and Single Bond provided higher microtensile bond strength compared with Clearfil S3 Bond. Universal adhesives with their acceptable performance can be applied in self-etch mode on both enamel and dentin.
