“…The adhesive failure was the most common failure followed by mixed failure in composite, which is in accordance with other study (38) as the majority of failures were adhesive which may be due to the nature of specimen and that the microtensile testing provide stress distribution at the interface so more adhesive failures and less cohesive failures (39,40) .…”

Purpose: This study was conducted to evaluate the effect of egg shell and white tea dentin pre-treatment on microtensile bond strength between resin composite and dentin surface. Materials and Methods: Forty-five extracted molar teeth were divided into three subgroups according to dentin pretreatment ; with no treatment (control ), Egg shell, and white tea. Each group was subdivided for microtensile testing into three equal subgroups, either after 24 hours (T0), after1 month (T1), and after 3 months (T2).The occlusal enamel was removed. And according to each group one of pretreatments was used. Resin composite blocks were fabricated on dentin after application of self etch adhesive. The teeth were longitudinally sectioned to get composite-dentin beams, two central beams were selected from 45 teeth in order to have 90 beams. Specimens were assessed after 2 storage periods in artificial saliva: either one month (T1) or three months (T2) storage period. Specimen were subjected to microtensile bond strength testing. Results: at T0, there was no statistically significant difference in mean μTBS between different dentin pre-treatments, while at T1 and T2, white tea group showed significantly the highest μTBS mean values, followed by egg shell group, then control group. Conclusion: Natural remineralizing agents could enhance microtensile bond strength of universal bonding system in self etch mode, and remineralizing potential of natural agents has stabilized by time.

Comparison of bond strength of universal adhesives using different etching modes: A systematic review and meta-analysis

This review aims to evaluate whether the etch-and-rinse or self-etch mode is the better protocol for dentin adhesion by universal adhesives. A total of 15 articles were included in the meta-analysis. Two reviewers performed a literature search up to October 2020 in four databases: PubMed, Web of Science, Embase, and the Cochrane Library. Without considering the difference in aging mode, the analysis of the immediate and long-term bond strength of dentin showed that there was no statistical significance between the etch-and-rinse and self-etch mode of universal adhesive, and the long-term bond strength decreased relative to the immediate. In vitro studies suggest that prior acid etching did not improve bond performance. Whether from the perspective of long-term bonding performance or simplifying operating procedures, the self-etch mode is preferred.

“…The divergence in outcomes can be attributed to the differences in types of adhesive systems and methodologies. Ozan et al, (12) who evaluated the dentin bond strength of universal adhesives, reported that their radiotherapy before restoration group had lower bond strength values than their no-radiotherapy group with the application of the etch&rinse mode. The divergence in outcomes can be related to the differences in the types of specimens they used (extracted radiotherapy-treated teeth).…”

“…Therefore, it is critical for an HNC patient to organize a timely treatment plan, with the use of the most beneficial adhesive system to achieve optimized treatment. However, there are controversial results, which are attributed to the selection of adhesive systems (11,12,13). Thus, adhesive systems must be chosen according to the substrate, and the selection of the most appropriate restorative material may be important under irradiated circumstances (14).…”

This study investigated the shear bond strength (SBS) of a universal adhesive to enamel/dentin; 1) that had undergone radiotherapy (RT) and 2) that were readily restored and had undergone RT. Enamel and dentin surfaces were obtained from 90 intact human molars. They were randomly divided into six groups according to the presence and timing of irradiation (RT0:no radiotherapy/control, RT1:RT before restoration, RT2:RT after restoration groups) and adhesive application modes (etch&rinse/ER, self-etch/SE)(n=15). A universal adhesive and resin composites were applied. The radiotherapy protocol was conducted with 60 Gy. The SBS test was subjected (1mm/min) and failure type analysis was performed. The resin-enamel/dentin interfaces were examined. Data were statistically analyzed. For enamel and dentin, the presence and timing of irradiation did not significantly influence the SBS values (p>0.05). For enamel, significantly higher SBS values were obtained using etch&rinse mode than self-etch mode (p<0.05). The predominant failure was mixed type. Loss of enamel prisms and obliterated irregular dentinal tubules were found for the radiotherapy-treated specimens. Resin tags were clearer in the irradiated enamel treated with ER than SE. Irradiation with different timings did not influence the bond strength to enamel and dentin, negatively. Irrespective of radiotherapy, the etch&rinse mode caused higher bond strength to enamel than self-etch mode.
