Dissolution of pulp tissue by aqueous solution of chlorhexidine digluconate and chlorhexidine digluconate gel.

摘要: Aim  To evaluate the activity of various root canal irrigants on bovine pulp tissue. Methodology  The tested were: 0.5, 1.0 and 2.5% sodium hypochlorite; 2% aqueous solution chlorhexidine digluconate; digluconate gel (Natrosol™); distilled water as control. Bovine fragments were weighed placed in contact with 20 mL each substance a centrifuge at 150 r.p.m. until total dissolution. Dissolution speed was calculated by dividing weight dissolution time. Statistical analysis performed using Kruskal–Wallis test. Results  Distilled both solutions did not dissolve tissue within 6 h. Mean speeds for hypochlorite 0.31, 0.43 0.55 mg min−1, respectively. solvent ability similar to that water. results solutions, statistically different (P > 0.01). Conclusions  Both preparations able tissue. All efficient dissolving tissue; varied concentration solution.
