Objective: To assess, in vitro, the ability of the ProTaper™ and WaveOne™ systems to reduce Enterococcus faecalis contamination in primary molars. Study design: Sixty roots of primary molars were contaminated with E. faecalis. Roots were randomly allocated to one of four groups (n=20): ProTaper™, WaveOne™, control A, or control B. The files used were S1 and S2/F1 and F2 (ProTaper™ system) and 25.08 (WaveOne™ system). In control group A, the root canal was left uninstrumented, whereas in control group B, the root canal was irrigated with NaCl 0.9%. E. faecalis was sampled from the root canal system before and after instrumentation and the Wilcoxon test and Mann–Whitney U were used. Results: There were no differences in E. faecalis counts between pre-instrumentation counts in the ProTaper™ and WaveOne™ (p>0.05). The ProTaper™ system led to an 89.36% reduction in E. faecalis burden, versus 78.10% with the WaveOne™ system (p>0.05). Instrumentation time was shorter with WaveOne™ (p<0.0001). Conclusions: The ProTaper™ and WaveOne™ systems were equally effective in reducing Enterococcus faecalis in primary molars. The WaveOne™ system was associated with shorter instrumentation time.

Endodontic Sealers

ABSTRACT Microorganisms invading the root canal system of a tooth may interact with the host tissue and cause pulpo-periapical pathosis. The goals of root canal treatment are to disinfect the root canal system and to prevent subsequent reinfection. The disinfection is attempted with endodontic instruments, irrigants, and medications. Due to the complex canal anatomy, microorganisms can persist even after thorough disinfection regimens are used. After disinfection, the canal is sealed with a root filling material along with sealers. To curtail residual microorganisms, root-filling materials should ideally be bactericidal, as well as biocompatible. In addition, the root filling materials are expected to act as a physical barrier to prevent the leakage of substrate to any residual microorganisms and the ingress of additional microorganisms. The aim of the present study was to assess the antimicrobial activity of various Endodontic sealers on the Enterococcus faecalis. Enterococcus faecalis is a microorganism commonly detected in asymptomatic, persistent endodontic infections. In the changing face of dental care, continued research on E. faecalis and its elimination from the dental apparatus may well define the future of the endodontic specialty.

ABSTRACT Introduction The main objective of root canal treatment is to disinfect the entire root canal system, and irrigation is an important step in reducing the bacterial load from the root canal system. However, irrigants currently used in the field of endodontics have their share of limitations, and the search for an ideal root canal irrigant continues. The use of herbal extracts as endodontic irrigants is today gaining popularity. Aims and objectives To evaluate and compare the antimicrobial potential of herbal extracts, such as neem (Azadirachta indica), triphala (Terminalia chebula), green tea (Camellia sinensis), and combination of neem and triphala as endodontic irrigants against Enterococcus faecalis. Materials and methods Freshly prepared extracts of neem, triphala, green tea, and 2% chlorhexidine were used to assess the antimicrobial efficiency against E. faecalis using the agar well diffusion test. Agar plates were incubated at 370°C for 24 hours in an incubator. The diameter of bacterial inhibition zones around each well was recorded to the nearest size in mm. Results Higher mean zone of inhibition was recorded in chlorhexidine followed by neem extract and combination of neem and triphala than triphala and green tea extract respectively. The lowest mean zone of inhibition was found in green tea extract. Conclusion From the present study, it can be concluded that neem leaf extract shows comparable zones of inhibition with that of chlorhexidine and combination of neem and triphala.
