Antimicrobial Potential of Calcium Hydroxide Chlorhexidine, Octenidol, Endoseptone and Combination of Calcium Hydroxide and Chlorhexidine against Enterococcus faecalis as Intracanal Medicament

Abstract

The complete microfloral debriment of the root canal is possible only through successful endodontic treatment. Due to complexicity constraints of root canal system complete microfloral removal by simply mechanical instruments is not sufficient. Therefore we aim to evaluate the antimicrobial efficacy of five different intracanal medicaments such as calcium hydroxide, chlorhexidiene, octenidol, endosepton and calcium hydroxide and chlorhexidine against Enterococcus faecalis. The Antibacterial activity of aforesaid medicaments was done against Enterococcus feacalis using agar disk diffusion method, over a period of 24 hrs and 72 hrs. The samples were divided into 6 groups. The zone of inhibition was measured after 24 and 72 hrs and were recorded in millimeters and compared with respect to control. There was a significant difference in the mean zone of inhibition at 24 and 72 hrs between calcium hydroxide, endoseptone, octenidol, calcium hydroxide and chlorohexidine combination, chlorohexidine and control group. Chlorohexidine was found to have maximum inhibitory efficacy followed by calcium hydroxide and chlorohexidine combination. Within the limitations of this study it may be concluded that Chlorhexidine can be used as an efficient intracanal medicament.

The effect of four different intracanal medicaments on the push-out bond strength of root canal sealers

“…Our study recorded the highest push-out bond strength when calcium hydroxide was used as an intracanal medicament [ 13 ]. Other researchers had similar findings and stated that calcium hydroxide Ca(OH) 2 used as a treatment for 14 days showed satisfying effects on the bond strength of AH Plus to root dentin [ 14 – 18 ]. However, according to Amin et al , intracanal treatment with Ca(OH) 2 for a week showed no changes in the bond strength of AH Plus.…”

“…The eugenol portion of these sealers is chelated by zinc oxide present in gutta-percha. Inappropriate polymerization of these sealers can cause stress on root canal walls, resulting in microleakage, marginal gaps, and a few clinical failures [ 14 ]. One side of the root canal may detach due to forces of polymerization shrinkage which may exceed its bond strength to root dentin, and a strong bond with the root canal dentin cannot be formed [ 15 ].…”
