Abstract


Background:  The present study was conducted to compare the fracture resistance of radicular dentin when intracanal medicaments such as CH, CHX, CHID, were mixed with LP for 1-week and 1-month time interval.  Material & method: The study was conducted on sixty single-rooted extracted human permanent premolars teeth and complete instrumentation was done. Samples were divided into five groups based on intracanal medicament used: Group 1 - no medicament was placed (CON), group 2 - mixture of 1.5 g of CH and 1 ml of 2% CHX (CHCHX), group 3 - mixture of 1.5 g of CH, 1 ml of CHX and 1 ml of 5% LP solution (CHCHXLP), group 4 – CH and iodoform (CHID), group 5- CHI and 1ml of 5%LP solution (CHIDLP). After storage period of each group for 1week and 1-month, middle 8 mm root cylinder was sectioned and tested for fracture resistance.  Results: At 1-month time interval, there was a statistically significant difference in fracture resistance between CHCHX and CHCHXLP groups.  Conclusion: Addition of LP has not decreased the fracture resistance of radicular dentin after 1-month.
