EVALUATION OF TENSILE STRENGTH OF GUTTA PERCHA CONES WITH DIFFERENT DISINFECTANT SOLUTIONS – AN IN VITRO STUDY.
Journal Title: IJAR-Indian Journal of Applied Research - Year 2018, Vol 8, Issue 2
Abstract
This study was done to evaluate the tensile strength of gutta-percha using 5% sodium hypochlorite NaOCl, 2% chlorhexidine CHX and 1% peracetic acid disinfectant solutions. 40 gutta-percha cones of size 30 (6% taper) were obtained from sealed packs as 4 different groups. Experimental groups were disinfected using 5% NaOCl, 2% CHX, 1% peracetic acid respectively except the control group. Then tensile strength of gutta-percha cones were measured using the universal testing machine. The mean tensile strength values for group I, II, III, IV are 7.003MPa, 8.49 MPa, 6.60MPa and 9.45MPa respectively. Results were subjected to statistical analysis one-way analysis of varience test and unpaired 't' test. 1% peracetic acid decreased tensile strength significantly as compared to 5% NaOCl and 2% CHX. The result concluded that the least decreased in tensile strength is for CHX followed by NaOCl and peracetic acid.
