“…Adhesion to root dentin is the critical property of root canal sealers for two important reasons: ( 1 ) there is decreased apical and coronal leakage by superior, and ( 2 ) the filling material is fixed and stops its dislocation during procedures. The chemical composition of sealers is the major factor in determining their adhesion characteristics [ 12 , 13 ].…”

“…They concluded that AH Plus sealer is more effective in avoiding fractures among the various sealer groups. There was no significant difference among MetaSEAL and MTA Fillapex groups regarding fracture resistivity [ 12 ]. One of the intracanal medicaments used in the present study is TAP, an amalgamation of triple antibiotics, which is usually applied to treat the necrotic pulp of open apex teeth and promote teeth revascularization and regeneration.…”

This study aimed to compare the effect of 4 different intracanal medicaments on the push-out bond strength of two sealers (AH Plus and MTA Fillapex). 100 single-rooted extracted premolar teeth were divided into 5 groups, with 20 samples in each group, one group being the control group. After cleaning and shaping procedures, the canals were filled with 4 different medicaments: calcium hydroxide, tri-antibiotic paste (TAP), Metapex, or Chlorhexidine (2%) gel for 2 weeks. Following this, the medicaments were rinsed away, and the samples in those sub-groups were obturated with gutta-percha/AH Plus or MTA Fillapex sealers. After 2 weeks of incubation, a 2-mm-thick middle section from each root was evaluated to test push-out strength. The obtained data were tabulated, and appropriate statistical analysis was performed (two-way ANOVA and LSD test). When comparing the average values, the bond strength values of AH Plus were significantly higher than those of MTA Fillapex (p<0.05) in all medicament groups. Based on the findings, we concluded that AH Plus had comparatively higher bond strength than MTA Fillapex. We also observed that AH Plus had higher bond strength in the presence of calcium hydroxide, whereas MTA Fillapex in the presence of Chlorhexidine. A comparison of the push-out bond strength shows that irrespective of the root canal segment or the final irrigant used, AH Plus showed higher values among all groups. The limitation of the current study was that the effect of TAP on the bond strength of endodontic sealers was not negative.

“…Chlorhexidine berperan sebagai penghambat matrix metalloproteinases (MMP) dan mencegah disintegrasi kolagen, sehingga memungkinkan penetrasi sealer resin yang lebih baik ke dalam jaringan kolagen. 20 Sealer berbahan dasar zinc oxide adalah yang paling banyak digunakan untuk obturasi saluran akar meskipun sifat resistensinya rendah terhadap gaya tekan, buruknya kemampuan untuk menembus tubulus dentin, dan kohesi molekulnya yang rendah. 21 Eugenol (2-Methoxy-4-allylphenol) dapat menyebar di dalam tubulus dentin dan komponen fenoliknya (2-Methoxy-4-allylphenol) dapat menonaktifkan molekul dalam rantai polimer yang terbentuk, mengganggu setting dan mengurangi kekuatan pelekatan.…”

Background:Resin-based sealers are widely used because they have good physical and biological properties and form micro-retention in dentin. There are also non-resin-based sealers. A non-resin-based sealer also has good micro-retention properties. The bond between dentin and the sealer can be improved by removing the smear layer. 2.5% NaOCl and 17% EDTA are the most common combination of irrigation solutions used to remove the smear layer. The use of 2% chlorhexidine after 17% EDTA at the end of irrigation will increase the antimicrobial effect and inhibit the activity of matrix metallo-proteinase (MMP).Objective: to determine push-out bond strength of obturation material with resin and non-resin sealers with 2.5% NaOCl, 17% EDTA and 2% CHX irrigation solution.Methods: The study used a true experimental method (post-test only group design). The treatment group (obturation with gutta percha and resin sealer; gutta-percha and non-resin sealer; gutta-percha only) were tested using a universal testing machine. Statistical tests using the Kruskal Wallis test and Mann Whitneytest.Results:Kruskall Wallis test showed that there were differences value of push-out bond strength in different obturation material with gutta percha and resin sealer; gutta-percha and non-resin sealer; gutta-percha only (p <0.05). The Mann Whiney test showed a significant difference bond strength between the non-resin sealer obturation group and gutta percha only group and between between the resin sealer obturation group and gutta percha only group (p<0.05).Conclusion:The use of sealer (a resin-based sealer and non-resin-based sealer) and 2.5% NaOCl, 17% EDTA and 2% CHX as irrigation solution can increase the bond strength of the obturation material.

Comparative evaluation of N-acetylcysteine and chlorhexidine as final irrigation on the push-out bond strength of different sealers

Aim: Using N acetyl cysteine (NAC) and Chlorhexidine as final irrigants, the study aims to examine the push out bond strength of distinct sealers. Materials and Methods: Access and biomechanical preparation were done on decoronated 80 single-rooted teeth. Canals were alternatively irrigated using 5ml of 5.25% NaOCl and 5ml of 17% EDTA solution during instrumentation. On the basis of final irrigation procedure, the samples are divided into two groups: Group 1 – NAC and Group 2 – 2% Chlorhexidine. Using paper points, canals were dried and subdivided depending on the sealers used, Group 1A and 2A- AH plus and 1B and 2B- BioRoot RCS. Teeth were obturated and middle root sections were tested for push-out bond strength using universal testing equipment. Statistical analysis was done. Results: NAC with AH-plus sealer had the maximum push-out strength, whereas Chlorhexidine with BioRoot RCS sealer had the lowest. Conclusion: NAC increases the bond strength of the obturating materials as the final irrigant. NAC can be considered as a final irrigant for endodontic therapy.
