Abstract: Context: The success of endodontic treatment mainly depends on effective irrigation methods to dissolve pulpal tissue, remove debris, and clean the complex root canal system. Sodium hypochlorite (NaOCI) is a widely used endodontic irrigant due to its tissue - dissolving and antibacterial properties. Aim: Quantitative evaluation of human pulp tissue dissolution at different temperatures of sodium hypochlorite. Materials and Methods: Twenty - four samples of human pulp tissue were collected from freshly extracted premolars. The samples were divided into two groups: Group I with normal saline and Group II with 5.25% NaOCI. Each group was further divided into two subgroups according to temperature (37?C and 60?C) and three divisions based on time intervals of tissue dissolution (1 minute, 5 minutes, and 60 minutes). Result: The results showed that normal saline did not show any dissolution of pulp tissue. In contrast, 5.25% NaOCl demonstrated a significantly higher tissue dissolution capacity compared to normal saline at both temperatures and all - time intervals. Less pulp dissolution was seen when kept in contact for 1 minute but increased subsequently when kept in contact for 5 minutes to 60 minutes at 60?C. Conclusion: According to the findings of the current study, it can be concluded that 5.25% NaOCl exhibits maximum pulp tissue dissolution at 60?C temperature when kept in contact with pulpal tissue for a minimum of 5 minutes and a maximum of 60 minutes.
