Comparison of efficacy of natural antioxidants on the adhesive bond strength of NaOCL treated dentin

To compare efficacy of Natural collagen crosslinkers on the adhesive bond strength of Naocl treated pulp chamber dentin. A total of 50 Mandibular molars are randomly divided into four groups according to the solution used. Group I: Negative Control: No treatment.Then, specimens are bonded with self-etch adhesive followed by composite restoration. These specimens are sectioned to produce sticks which are subjected to bond strength test.
