“…This supports some studies in which Ca(OH) 2 remnants improved the seal of a calcium hydroxide-based (25) and a resin-based sealer (23) and improved the marginal adaptation of MTA (30). However, the bonding of AH Plus and MTA Fillapex in this study was not affected by Ca(OH) 2 , which is in agreement with other studies (24,26,27,29).…”

“…The effect of one-week CH medication on the improved marginal adaptation of an MTA-apical plug has also been demonstrated. [26] This improvement was attributed to the conversion of CH to calcium carbonate or to the reaction of MTA with residual CH. Thus, in the present study, favourable results from the CH-treated group may be related to the Ca CC ions supplied by the residual CH, which was previously suggested to improve the adhesion of MTA.…”

The aim of the present study was to evaluate the effect of the intracanal medicaments used in regenerative endodontic treatment on push-out bond strength (PBS) of mineral trioxide aggregate (MTA) and Biodentine (BD). The root canals of 102 maxillary incisors were enlarged to simulate immature roots and were randomly divided into three groups (n D 34): a control group (no intracanal medicament) and two test groups, subjected to calcium hydroxide (CH) or triple antibiotic paste (TAP) medication for two weeks. After the medication removal, each group was divided in two subgroups and the coronal portion of each canal was filled with MTA or BD. After one week of storage, the coronal region of each root was horizontally sectioned and push-out test was performed. Data were analyzed by two-way analysis of variance and the Tukey post hoc test (P D 0.05). PBS values were significantly affected by the type of material (P < 0.001) and the type of medication used (P D 0.049), but no interaction was found (P D 0.97). The BD group showed significantly higher push-out resistance values than those of the MTA group (P < 0.001). TAP showed the lowest PBS values, which were significantly lower than those of the control group (P D 0.043) but not than those of CH (P D 0.229). After a two-week application period, TAP seemed to decrease the PBS of both cements, while CH did not. BD appeared to have higher PBS compared to MTA, regardless of medication.

“…The sealer penetration into dentinal tubules is related to its physicochemical characteristics as composition, film thickness and flow (16,22). The effect of CH on sealer tubular penetration could be related to the properties of the sealer because it depends on the interaction between the sealer and the residual CH (5,23,24). When CH was used, MTA Fillapex showed better tubular penetration than AH Plus in the middle third.…”

Objective: The aim of this study was to evaluate the effect of a calcium hydroxide (CH) dressing on the tubular penetration of two endodontic sealers, AH Plus (Dentsply Maillefer, Ballaigues, Switzerland) and MTA Fillapex (Angelus, Londrina, Brazil). Methods: Seventy-two mandibular premolars with a single root canal were prepared with ProFile.04 rotary instruments (Dentsply Maillefer) and divided into four groups. In two groups, an intracanal CH dressing was placed for 15 days. The obturations were performed with lateral condensation of gutta-percha in combination with one of the tested sealers. The roots were transversely sectioned at the apical and middle levels. The percentage of sealer penetration in the root canal walls and the percentage of impregnated dentin area in the transverse sections were obtained using confocal laser scanning microscopy. Statistical analysis was performed using one-way analysis of variance (ANOVA) and Games-Howell test. Results: The CH dressing reduced the mean value of tubular penetration in the middle third of teeth obturated with AH Plus (P<0.01), whereas no difference was observed at the apical sections for both sealers. Conclusion:The CH dressing did not interfere with the apical penetration of both tested sealers, however, decreased the tubular penetration in the middle third of the AH Plus root canal fillings. Overall, MTA Fillapex presented higher tubular penetration than AH Plus obturations. Keywords: Calcium hydroxide, confocal laser scanning microscopy, epoxy resin-based root canal sealer, mineral trioxide aggregate-based sealer
