“…The ideal endodontic therapy stands on good chemical cleaning and requires complete filling of the canal space with an inert material 21 .the obturating material should be in strong contact with the canal walls to make it more perfect and thus can be achieved by making the gutta-percha and the sealer into homogenous mass. The ysiochemical structure of the endodontic sealers is an important role in bond strength and tissue tolerance with antimicrobial outcome (22,23) . This study was designed to demonstrate the effect of EDTA and Chlorohexidine on push out bond strength AH plus Resin Based Sealer and Total Fill BC Sealer.…”

Purpose: This study was designed to evaluate the impact of irrigating solutions on push out bond strength of Bio-ceramic and resin based endodontic sealers. Materials and Methods: sixty extracted human teeth with single root and single canal were prepared with RACE FKG rotary files (#35, 0.06) taper. The specimens were divided into two experimental groups according to the final rinse used (30 samples each): Group (I) irrigated with 17%EDTA, Group (II) irrigated with 2% Chlorohexidinedigluconate (CHX). Each group was subdivided into two subgroups according to the sealer used (15 samples each). Total Fill Bio-ceramic sealer, and AH Plus Sealer The specimens were obturated by single cone gutta-percha with vertical condensation technique. Results: Final irrigation with EDTA resulted in the highest bond strength of bioceramic sealer to dentin of the root which was statistically different from irrigation with chlorohexidinedigluconate (CHX). Bond strength values were as follows: EDTA>CHX. Conclusion: The type of final irrigation affects the adhesion of Total Fill Bio-ceramic and AH plus sealers to root canal dentin.

“…The use of a chelating agent such as 17% EDTA solution to remove the inorganic component, followed by 5.25% NaOCl solution to dissolve any remaining organic component is the most commonly used regimen to remove the smear layer 22,23,24 . EDTA easily enters dentinal tubules due to its low surface tension and eliminates smear layer up to the depth of 2.5-4 μm 25 .…”

Aim of the study: The aim of this study was to compare the adaptation of two calcium silicatebased root canal sealers with a resin-based sealer to root canal walls at the middle and apical levels using scanning electron microscope. Material and methods: Twenty-six single-canalled lower premolars were instrumented and randomly divided into three groups according to the sealer used with gutta-percha (n=8); AH plus, Bioroot RCS, and Endoseal MTA. Two random specimens served as the blank control group to assess the smear layer removal from the dentinal walls. Teeth were sectioned at middle and apical levels and gap width was evaluated using scanning electron microscope. Data were statistically analyzed with significance level set at p ≤ 0.05. Results: At the apical and mid-root levels, the highest mean values were found in Endoseal MTA group followed by Bioroot RCS group while the lowest mean value was found in AH Plus group with statistically significant difference between all groups. Statistically significant differences were found between Endoseal MTA and each of Bioroot RCS and AH Plus groups. No statistically significant difference was found between Bioroot RCS and AH Plus groups. Conclusions: AH Plus and Bioroot RCS showed statistically better results than Endoseal MTA regarding adaptation to the root canal walls.

“…Another reason to use EDTA additionally was that NaOCl alone is not effective in the removal of intracanal smear layer, especially in the apical third of the canal. [ 28 ] To prevent cross contamination with desired bacterial growth, all the samples were sterilized in autoclave at 121°C, 15 lbs pressure for 20 min. An external coating with nail polish was done in all the samples to seal the dentinal tubules so as to prevent the seepage of bacteria.…”

Introduction:In endodontics, despite careful instrumentation and antimicrobial irrigation, root canals still harbor cultivable microorganisms. Such cases require intra canal medicament that eliminates the microbial inhabitants from the canals. Recent trend advocates the use of herbal extracts due to easy availability, cost-effectiveness, low toxicity, and lack of microbial resistance. Hence, in the present study, Neem, Tulsi, and Guduchi extracts were used as intracanal medicaments.Aim:This study aimed to evaluate and compare the antibacterial efficacy of Neem, Tulsi, Guduchi extracts, and chlorhexidine against Enterococcus faecalis, when used as intracanal medicaments.Materials and Methods:One hundred and twenty-five extracted human teeth, inoculated with E. faecalis, were divided into four experimental groups and a control group (n = 25 in each group). The experimental groups were treated with chlorhexidine, Neem, Tulsi, and Guduchi extracts and their antibacterial property was evaluated by estimating microbial counting (CFU/ml).Results:The reduction in bacterial count for chlorhexidine, Neem, Tulsi, and Guduchi groups was 60.76%, 51.98%, 37.73%, and 34.93%, respectively. Statistically significant difference in reduction of bacterial count was observed in all the groups, when compared with the control group.Conclusion:Among all the herbal extracts, Neem was found to be the most potent medicament followed by Tulsi and Guduchi. However, chlorhexidine was found to be at epic.
