Use of a bottle warmer to increase 4% sodium hypochlorite tissue dissolution ability on bovine pulp.
The aim of this study was to evaluate the tissue dissolution ability of 4% sodium hypochlorite at increasing temperatures with the use of a baby bottle warmer. Twenty pieces of bovine pulp tissue from freshly extracted incisors and canines were weighted and randomly distributed among four groups in accordance to the exposure to 4% sodium hypochlorite at different temperatures: group C--room temperature (20.5 degrees C--control); group T1--45 degrees C; group T2--60 degrees C; group T3--75 degrees C. The samples were placed within test tubes when the solution reached the desired temperature. Time taken for the dissolution was recorded. One-way anova with logarithmical transformation and Duncan post-hoc was used (P = 0.05). There was a statistically significant increase in speed of pulp dissolution from group T1 to group C and from groups T2 and T3 to group T1; group T2 and T3 displayed similar dissolution speeds.
