“…The tubules within the coronal and middle thirds of the roots are much more permeable than those in the apical thirds due to the presence of tubular sclerosis, smaller diameter, and a reduced number of dentinal tubules in this region (18). According to the results of this study, in all experimental groups, lower penetration of irrigant was observed at the apical 2-mm level than at 5 mm, as observed in other studies (19)(20)(21)(22)(23). Further, relatively straight canals were used in this study because canal curvatures can limit irrigant penetration.…”

The aim of this in vitro study was to compare the percentage of penetration of three final irrigant into the dentinal tubules after application of several irrigation techniques. Mandibular premolars were divided into nine groups (n:10): chlorhexidine (CHX) + conventional syringe irrigation (CI), CHX + EndoActivator (SI), CHX + Er,Cr:YSGG laser (LAI), QMix + CI, QMix + SI, QMix + LAI, Irritrol + CI, Irritrol + SI and Irritrol + LAI. Following irrigation, all roots were horizontally sectioned at 2 mm and 5 mm from the apex and examined using a confocal laser scanning microscopy. QMix exhibited a significantly higher penetration percentage than CHX at the apical section (P < 0.05). In the Irritrol group, SI displayed a significantly higher penetration area than CI in the middle section. Statistically significant differences were also determined between middle and apical section (P < 0.05). Use of QMix with different agitation technique seems advantageous in dentinal tubule penetration.

“…20,21 Comparing the effect of QMix to EDTA to remove the smear layer, according to the literature, QMix acts as effectively as 17% EDTA based on the number of open dentinal tubules. 7,20,22,23 In the present study, the use of QMix showed similar results to EDTA for the sealers AH Plus and Pulp Canal EWT and was superior to MTA Fillapex. The reason for the satisfactory wettability with the use of QMix is associated to the action of EDTA to remove the smear layer and the presence of a surfactant agent combined with CHX.…”

Objective: the present study aimed to evaluate the wettability of different sealers in contact with dentin treated with irrigants used for smear layer removal, after the use of chlorhexidine as chemical auxiliary substance. Material and Methods: thirty single-rooted teeth were used. The crowns were removed and the roots sectioned vertically, resulting in two segments, which were then flattened. Thus, 120 samples measuring 5 mm were obtained. They were immersed in 2% chlorhexidine gel (CHX) for 10 minutes and washed with distilled water (AD) before being subjected to the final irrigant for smear layer removal. The following irrigation protocols were evaluated: control group-CHX+AD+AD+AD; group E-CHX+AD+17%EDTA+AD; group Q-CHX+AD+QMix+AD; group Et-CHX+AD+18%HEBP+AD. The samples were dried and the contact angle was analyzed using a goniometer. The sealers evaluated were: AH Plus (AH), Pulp Canal Sealer EWT (PCS) and MTA Fillapex (MTAF). In each drop of sealer, 60 measurements were made and the flow was observed for 1 minute. The dynamic wettability of the sealers was calculated. Data were statistically analyzed. Results: in all sealers, the presence of smear layer disfavored the wettability. EDTA and QMix favored the wettability of AH and PCS. For the MTAF, QMix showed the best performance, followed by EDTA. HEBP showed statistically lower results, similar to the control. Conclusion: Solutions used for smear layer removal, after the use of chlorhexidine during preparation, influenced the wettability of AH Plus, Pulp Canal Sealer EWT and MTA Fillapex sealers.

This study investigated the dentinal tubule penetration of mineral trioxide aggregate (MTA), NeoMTA Plus and Biodentine placed by either manual condensation or ultrasonic activation in simulated open apex model. Standardized divergent open apex models were created using palatal roots of 60 human maxillary molars and divided into six groups according to the used cements and activation methods (n = 10): MTA‐manual condensation, MTA‐ultrasonic activation, NeoMTA Plus‐manual condensation, NeoMTA Plus‐ultrasonic activation, Biodentine‐manual condensation, Biodentine‐ultrasonic activation. For the measurement of penetration, the cements were mixed with 0.1% Rhodamin B and 6‐mm apical portions of each root canal were obturated in an orthograde direction. The roots were embedded into acrylic blocks, and 1‐mm‐thick sections were obtained at 3 mm from the apex. Specimens were mounted onto glass slides and scanned under a confocal laser scanning microscope (CLSM) and stereomicroscope. Dentinal tubule penetration areas, depth and percentage were measured using LSM and ImageJ software. The data were analyzed using two‐way analysis of variance (anova) with Bonferroni correction (α = 0.05). No correlation was found between stereomicroscope and CLSM analyses (p > .05). CLSM analysis showed no significant differences between MTA, NeoMTA Plus, and Biodentine groups when manual condensation was used (p > .05). Ultrasonic activation did not increase the tubular penetration of MTA, NeoMTA Plus or Biodentine as compared to manual condensation of each material (p > .05). MTA, NeoMTA Plus and Biodentine showed similar tubular penetration when manual condensation was used. Ultrasonic activation of these cements had no effect on tubular penetration of each material as compared to the manual condensation counterparts.
