ABSTRACT:Aim and objectives

Aim: Is to evaluate the two different natural crosslinking agents citric acid and grape seed extract.

Objective: To know the difference between the two agents on bond strength of fiber post on to root dentin using self-etch adhesive.

Materials and Methods

1. 30 Single rooted maxillary anterior teeth with similar root segments and fully developed apices were selected.

2. Root canal treatment is performed and post space preparation is done using #2 peeso reamers and irrigated with 2.5% NaOCl and 17% of EDTA and dried with paper points and then divided in to 3 groups according to pretreatment used.

Group 1: No pretreatment, only conventional self-etching & bonding. (Control Group).

Group 2: Pretreatment with 10% citric acid for 5 Minutes.

Group 3: Pretreatment with 6.25% Grape seed extract for 5 Minutes.

3. The post space treated with self-etch adhesive and fiber post is bonded using flowable composite

4. Bond strength evaluation is done by transversely sectioning the roots of each group of 1.0 MM, thickness and 3 sections were obtained and embedded in acrylic resin block.

Micro push-out bond strength was measured using universal testing machine and SEM analysis is done to classify the facture pattern.
