Abstract

The action of chemicals such as calcium hydroxide (Ca(OH)(2)) and sodium hypochlorite (NaOCl) that are used as tissue solvents may be enhanced by prolonged contact. The objective of this study was to determineif sealing Ca(OH)(2) and NaOCl into the canal space would improve debridement of both the main canal and areas inaccessible to files. Mesial root canals of 75 freshly extracted mandibular molars were step-backhand-instrumented. Another six molars were controls. Either Ca(OH)(2), NaOCl, or no medication was sealed in the canals for 1 or 7 days. Canals were finally irrigated with H2O and prepared for histological evaluation. The cleanliness of main canals and inaccessible areas (isthmiand fins) at the apical, middle, and coronal thirds was examined, scored, and compared by nonparametric statistical analysis. Results showed no significant differences among different groups in either the 1-day or 7-day time intervals in either the main canal or inaccessible areas. Instrumentation combined with NaOCl irrigation alone accounted forthe removal of tissue in the main canal. In conclusion, in this system, prolonged contact with Ca(OH)(2) and NaOCl was similarly ineffective; neither contributed significantly to canal debridement.
