次亞鹽素酸나트륨溶液의 齒髓組織에 對한 溶解效果 = The Effect of Solvent Action of Sodium Hypochlorite Solution on Pulp Tissue

다국어 초록 (Multilingual Abstract)

Sodium hypochlorite solution has been widely used as endodontic irrigant due to its ability to dissolve pulp tissue debris and its antimicrobial action.
This in vitro study was conducted to evaluate the solvent action of sodium hypochlorite solution on vital plup tissue under various conditions include concentration, exposure time, and temperature. The percentage of weight loss due to pulp tissue dissolution was calculated with weight difference of lyophilized specimens before and after the exposure to test solutions.
The results were as follows;
Statistical analysis indicated that the ability of both 5.0％ and 2.5％ sodium hypochlorions to dissolve pulp tissue was sighificantly greatet than that of distilled water, but no significant difference was found between 5.0％ and 2.5％ sodium hypochlorite solutions.
There was no significant increase in the pulp tissue dissolving of sodium hypochlorite solutions, as exposure time increased 2 minutes, 5 minutes, and 10 minutes.
Of the given temperatures, no significant difference was found in the solvent action of sodium hypochlorite solution on pulp tissue between 20℃ (room temperature) and 37℃ (body temperature).
