The Effect of Chloroquick on Fracture Resistance of Root Filled Teeth- An In-Vitro Study
Main Article Content
Abstract
Aim: To evaluate and compare the fracture resistance of endodontically treated teeth irrigated with different irrigating solutions under instron testing machine.
Materials and Methodology: Hundred extracted, human, single rooted mandibular premolars, recently extracted from patients for orthodontic purpose were selected. All the teeth were decoronated upto a standardised length of 12 mm. All the teeth were then biomechanically prepared upto size F4 and chemomechanically irrigated with different combinations of irrigants : Group 1: Chloroquick, Group 2: 5% EDTA(ethylenediamine tetra acetic acid) and 2.5% NaOCl(so, Group 3: 17% EDTA and 2.5% NaOCl, Group 4: 5% EDTA, Chloroquick and 2% Chlorhexidine and Group 5: 17% EDTA, Chloroquick and 2% Chlorhexidine followed by insertion of F4 gutta percha cones and application of AH Plus 26 sealer. All teeth irrespective of the groups were stored at 370C and 100% relative humidity for 14 days to allow sealer to set and each group was subjected to instron testing machine to evaluate their fracture resistance. The force required to fracture each specimen was recorded in Newtons and data were analysed statistically using analysis of variance ( ANOVA) test and Post- Hoc Tukey test.
Results: The mean fracture resistance of Group 5 was highest followed by Group 3, Group 1, Group 4 and Group 2. (Group 2<Group 4<Group 1<Group 3<Group 5).
The mean fracture resistance of Group 5 was significantly higher than rest of the groups (P<0.001) and also of Group 3 was significantly higher than other groups.
Conclusion: In context to all the irrigating solutions used for chemomehanical preparation, Chloroquick and it’s combination with 17% EDTA and 2% Chlorhexidine showed higher fracture resistance.
