“…Published literature had indicated that this area could prove challenging during preparation and subsequent filling, especially with cold lateral compaction 4) . AH Plus sealer exhibited the least number of gapcontaining regions, a finding consistent with previous studies 34,35) . The superior adaptation of AH Plus could be due to its ability to bond to root dentin chemically by reacting with any exposed amino groups in collagen to form covalent bonds between the epoxy resin and collagen 28) .…”

This study evaluated and compared the sealer thickness and interfacial adaptation of bioceramic sealers (Sankin Apatite III, MTA Fillapex ® , EndoSequence ® BC) to root dentin against AH Plus ® sealer. Sixty extracted single-root premolars were prepared and equally divided into four groups. Sealers were labeled with 0.1% Rhodamine B fluorescent dye. Roots were dissected along the transverse plane at 1 mm (apical), 3 mm (middle), and 6 mm (coronal) levels. Sealer-to-whole canal area ratio was evaluated. Percentage of gap-containing region to canal circumference was calculated using a confocal laser microscope. Sealer thickness was significantly higher at apical and middle levels than at coronal level. EndoSequence BC had the significantly highest thickness compared with MTA Fillapex and AH Plus. The coronal level had significantly less interfacial gaps compared with apical and middle levels. Bioceramic sealers showed more gaps compared with AH Plus, with no significant differences among them.

“…The results are in accordance with our finding. Eric Balguerie et al 7 also observed AH Plus with best tubular adaptation and penetration followed by Acroseal, when compared with glass ionomer and zinc oxide eugenol sealer. The sealer penetration depth in the dentinal tubules depend on factors like smear layer removal, dentinal permeability, root canal dimension, and the physical and chemical properties of the sealer.…”

“…The sealer penetration depth in the dentinal tubules depend on factors like smear layer removal, dentinal permeability, root canal dimension, and the physical and chemical properties of the sealer. 7,25 An acceptable flow within the working time is important for any root canal sealer in order to reach and seal the apical foramen and lateral dentinal wall irregularities. 20 Studies have shown that the flow of AH Plus is comparable or significantly higher than other sealers tested.…”

“…6 The sealer can fill the irregularities of the root canal wall and the dentinal tubules which cannot be filled by gutta-percha. 7 Regardless of the technique used, studies have shown that gutta-percha without sealer will not seal the root canal. 8 Sealers are resorbable when exposed to tissues and tissue fluids, 9 but breakdown products from the sealers may have an adverse effect on the proliferative capability of periradicular cell populations.…”

Abstract:Objective: This study was designed to compare the level of apical microleakage of root canal sealers; Acroseal, AH Plus, Endoflas FS and Endomethasone N, with laterally condensed gutta percha by level of apical dye penetration. Materials and Methods: Freshly extracted sixty permanent maxillary anterior teeth were divided randomly into four groups. Shaping and cleaning of teeth was done followed by obturation with gutta percha and four different root canal sealers. Samples were immersed in 2% methylene blue dye solution in individual dappen dish and stored in the solution for 30 days. The roots were split longitudinally with a chisel in two halves and observed under stereomicroscope. Apical microleakage measured from the apex to the most coronal extent of dye penetration. Results: Minimum microleakage was observed with AH Plus with mean value 2.140 mm, standard deviation 0.817. The maximum microleakage was observed with Endomethasone N with mean value 3.858 mm, standard deviation 1.840. There was no statistically significant difference in microleakage between Acroseal, AH Plus, and Endoflas FS. Endomethasone N showed highest level of microleakage than other three groups under the test condition, which was statistically significant. Conclusion: The microleakage was the lowest for the AH Plus and increased in the following order, Endoflas FS, Acroseal, Endomethasone N.

“…According to Tronstad et al (2000), tight sealing of the canal space is necessary to maintain satisfactory condition of the periapical tissue [8] [9]. Therefore, the physical properties that need to be observed from a root canal sealer is its ability to adhere with the root canal wall and gutta-percha, the solubility against the body tissue fluid, and its stability after hardened.…”

Background: One of the ideal properties of a root canal sealer is to have a good sealing ability, especially at the apical third of the root. Objective: To evaluate the comparison of the apical leakage between obturation using bioceramic sealer (BS) and polydimethylsiloxane sealer (PS). Materials and Methods: Thirty-six mandibular premolars were equally divided into two groups and were obturated with single cone technique. The sealers used for Group I and Group II were BS and PS respectively. After obturation, the samples were incubated (37˚C, 24 h), sealed with two coats of nail polish except for 2 mm from the apex, submerged in the Indian ink for 7 days, decalcified, dehydrated, and made transparent according to Robertson technique. Dye penetration was evaluated under stereomicroscope. Samples without dye penetration were given score 0, dye penetration ≤ 0.5 mm were given score 1, 0.51 -1 mm were given score 2, and >1 mm were given score 3. Result: The largest proportion distribution in BS group was at the score 1 (55.6%), whereas in PS group was at the score 2 (44.4%). Conclusion: Bioceramic sealer showed similar apical leakage to polydimethylsiloxane sealer. Clinical Relevance: Based on this study, bioceramic sealer can be recommended to be used as sealer with low level of apical leakage as well as polydimethylsiloxane sealer.
