“…When observed under X-ray diffraction and SEM analysis, this adherent interstitial layer is indistinguishable from hydroxylapatite in composition and structure. 4 The physical properties of epoxy resin-based sealers are appreciable and also have a very good apical sealing ensuring adequate biological performance, but it has several disadvantages in clinical use, radiopacity, and retreat ability. Thus, there remains no perfect adhesive material designed solely for endodontic purposes and becomes important to develop one which is suitable to use in such procedures.…”

Aim: This study aims to compare the marginal adaptation and sealing ability [mineral trioxide aggregate (MTA)-Fillapex, AH Plus, Endofill sealers] of root canal sealers. Materials and methods:In the present study, the inclusion criteria include 45 single-rooted extracted mandibular premolar teeth, with single canal and complete root formation. The sectioning of the samples was done at the cementoenamel junction using a low-speed diamond disc.Step-back technique was used to prepare root canals manually. The MTA-Fillapex, AH Plus, and Endofill sealers were the three experimental sealer groups to which 45 teeth were distributed. Under scanning electron microscope (SEM), marginal gap at sealer and root dentin interface were examined at coronal and apical halves of root canal.Results: Among the three maximum marginal adaptations were seen with AH Plus sealer (4.10 ± 0.10) which is followed by Endofill sealer (1.44 ± 0.18) and MTA-Fillapex sealer (0.80 ± 0.22). Between the coronal and apical marginal adaptation, significant statistical difference (p = 0. Kannur, Kerala, India, e-mail: vimalremy@gmail.com there was a statistically significant difference (p < 0.05) found between the above two groups at coronal and apical third. Conclusion:The present study proves that AH Plus sealer has a better marginal adaptation when compared with other sealers used.Clinical significance: For sealing space of crown wall and main cone in root canal treatment, sealers play an important role. The other advantages of sealers are that they are used to fill voids and irregularities in root channel, secondary, lateral channels, and space between applied gutta-percha cones and also act as tripper during filling.

“…However, several studies have shown that some of these materials may cause cellular degeneration and delayed wound healing of periapical tissues [29, 30]. The cytotoxic effect of these endodontic sealers may be caused by heavy metals released from the set materials [11, 31]. …”

Objective. The present study assessed the chemical elements in two novel calcium silicate-containing root canal sealers, BioRoot RCS and Well-Root ST, compared to a calcium silicate-containing root canal sealer that has been on the market for several years, MTA Fillapex, and epoxy resin-based sealer AHPlus. Material and Methods. The sealers were mixed and manipulated according to the manufacturers' instructions. Twelve cylindrical molds (inner diameter 4 mm; height 3 mm) were placed on a glass petri dish and packed with the materials. The dish was transferred to an incubator. After 72 h the molds were examined by scanning electron microscopy and energy dispersive X-ray microanalysis. Results. BioRoot RCS and Well-Root ST had high peaks of calcium, zirconium, oxygen, carbon, silicon, and chlorine. Well-Root ST also had sodium, magnesium, aluminum, and titanium peaks. MTA Fillapex and AHPlus had carbon, oxygen, calcium, titanium, and bismuth peaks. A silicon peak was also observed for MTA Fillapex, and zirconium and tungsten peaks for AHPlus. Conclusion. BioRoot RSC had the highest degree of purity. The clinical implication of metals contained in the other sealers needs to be investigated.

“…This layer hermetically seals the root canal, thereby eliminating remaining microbes. The MTA sealer is composed of calcium oxide which, every time it contacts water, creates Ca(OH) 2 that breaks into calcium and hydroxyl ions, thereby maintaining a high pH in the tissue [15][16][17][18].…”

“…Calcium hydroxide (Ca(OH) 2 ) sealer, which is biocompatible, has limited antimicrobial activity [4,5]. The mineral trioxide aggregate (MTA) sealer has good adhesion, hydrophilic, biocompatibility, and antimicrobial properties [6].…”

Objective: The objective of this study was to evaluate the antimicrobial activity of mineral trioxide aggregate (MTA) and calcium hydroxide (Ca(OH)2)sealers on Enterococcus faecalis at various time points after the preparation of the sealer.Methods: Antimicrobial activity of MTA and Ca(OH)2 sealer on E. faecalis (ATCC 29212) was assessed by the direct contact test immediately, 1 day,and 7 days after the preparation of the sealer.Results: The antimicrobial effect of MTA sealer was greatest 1 and 7 days after the preparation of the sealer. The effect of Ca(OH)2 was greatest 1 dayafter the preparation of the sealer.Conclusion: MTA sealer showed constant antimicrobial activity on E. faecalis overtime. By contrast, Ca(OH)2 sealer showed decreasing antimicrobialactivity overtime, with the greatest antimicrobial activity being 1 day after the preparation of the sealer.
