Tissue dissolution and modifications in dentin composition by different sodium hypochlorite concentrations
OBJECTIVES To determine the organic matter dissolution and changes in dentin chemical composition promoted by different concentrations of NaOCl over time. MATERIAL AND METHODS Fragments of bovine muscle tissue were weighed before and after 5, 10, and 15 min of immersion in the groups (n=10): G1- 0.9% saline solution; G2- 1% NaOCl; G3- 2.5% NaOCl; and G4- 5% NaOCl. Bovine dentin fragments were...
متن کاملPulp tissue dissolution capacity of sodium hypochlorite combined with cetrimide and polypropylene glycol.
This study evaluated the influence of the addition of cetrimide and polypropylene glycol to sodium hypochlorite (NaOCl) on its capacity to dissolve pulp tissue. Bovine pulp fragments with standardized weight and volume were immersed for 5, 15 and 30 min in 2 mL of NaOCl and Hypoclean (NaOCl added with cetrimide and polypropylene glycol) solutions at 5.25%, 2.5%, 1%, 0.5% and 0.25% and afterward...
متن کاملSodium hypochlorite with reduced surface tension does not improve in situ pulp tissue dissolution.
INTRODUCTION Sodium hypochlorite (NaOCl) solutions with added wetting agents are advertised to dissolve necrotic tissue in root canals faster than their counterparts without a lowered surface tension. This was tested in the current study, and the null hypothesis formulated was that there was no difference between a commercially available NaOCl solution with a lowered surface tension (Chlor-XTRA...
متن کاملEffects of calcium hydroxide and sodium hypochlorite on the dissolution of necrotic porcine muscle tissue.
The dissolving effect of the endodontic medicaments calcium hydroxide (Ca(OH)2) and sodium hypochlorite (NaOCl) on necrotic tissue was studied. Pieces of necrotic porcine muscular tissue were placed in either a 0.5% NaOCI solution (Dakin's solution), Ca(OH)2 mixed with water, or a NaOCI solution following pretreatment in Ca(OH)2 for various time intervals. The tissue pieces placed in 0.5% NaOCl...
متن کاملThe effects of sodium hypochlorite and calcium hydroxide on tissue dissolution and root canal cleanliness.
In this in vitro study, we investigated the efficacy of sodium hypochlorite (NaOCl) and calcium hydroxide (Ca(OH)2) in dissolving necrotic tissue and cleaning root canals. In the first part of the study, 0.5% NaOCl solution and Ca(OH)2 paste and solution were tested with samples of necrotic bovine muscle in different treatment modes and for different periods. The necrotic tissue was weighed bef...
