“…This could be attributed to the viscous nature of its vehicle. [ 9 ] High pH and calcium ion release by iRoot SP and MTA Fillapex groups can be attributed to the presence of nanoparticles providing a homogenous mixture, high solubility, and good flow characteristics which are important in determining the diffusion of calcium and hydroxyl ions from a material. [ 5 ] Furthermore, iRoot SP being hydrophilic, possesses low contact angle, and allows good adaptation with canal walls.…”

Aim:The aim of this study was to compare the effect on fracture strength, pH and calcium ion diffusion from mineral trioxide aggregate (MTA) Fillapex, iRoot SP, and Ultracal when used for repair of simulated root resorption defects.Materials and Methods:Three sets of 40 teeth each were used, and biomechanical preparation was done. Resorption cavity was made at 5 mm from the apex. Teeth were filled with different experimental materials. In control group, saline was used. Samples of fracture resistance were stored in an incubator for 3 months and then subjected to the universal testing machine. To evaluate the pH and calcium ion release were checked at 1 day and 1, 2, 3, and 4 weeks intervals. Data were recorded and statistical analysis done by one-way analysis of variance followed by post-hoc Tukey test.Results:Highest fracture resistance was seen in MTA Fillapex followed by iRoot SP, control, and then Ultracal group. Teeth filled with iRoot SP showed highest pH and calcium ion release followed by MTA Fillapex and Ultracal group.Conclusion:Bioceramic sealers showed high pH, calcium ion release, and good root reinforcement potential. Initial dressing of calcium hydroxide followed by obturation with Gutta-percha and bioceramic sealer may be considered as an alternative treatment modality for inflammatory resorption.

“…However, Ultra Cal XS contains 3% propylene glycol and 2% methylcellulose [ 53 , 54 ]. Propylene glycol is a viscous vehicle that reduces dispersion and diffusion due to its high molecular weight but maintains prolonged release and improves handling of the material [ 11 , 55 ].…”

Background There is an increasing demand to find a potent antibacterial agent against endodontic pathogens with the least toxic effect. The study aimed to evaluate the antibacterial activity of Lactobacilli probiotics on Enterococcus faecalis (E. faecalis) in comparison to calcium hydroxide paste. Methods The study involved two stages; (stage one): determination of the antibacterial properties of three strains of Lactobacilli probiotics supernatants (PS); Lactobacillus plantarum, Lactobacillus rhamnosus, Lactobacillus acidophilus, and a cocktail mix of the three supernatants against E. faecalis using agar well diffusion method in both solution and gel phase. The formed zones of inhibition (ZOI) were measured in millimeters (mm) and compared to each other. PS solution and gel of the largest ZOI were further compared with calcium hydroxide paste (35% Ultra Cal XS Ca(OH)2) This was followed by (stage two): assessment of the minimum inhibitory concentration (MIC) of the PS that showed the largest ZOI against E. faecalis by agar well diffusion assay for both PS solution and gel. Results All supernatants showed growth inhibition against E. faecalis, and the cocktail mix showed the largest ZOI. However, no significant difference was found between the supernatants in both the solution and gel phases (p > 0.05). Ca(OH)2 showed a significantly lower effect than both the cocktail mix solution and gel (p < 0.05). The MIC of the cocktail mix solution and gel against E. faecalis was 50 mg/ml. (p > 0.05). Conclusion PS has an antibacterial effect on E. faecalis and was more effective than Ca(OH)2.Lactobacilli probiotics could be a promising antibacterial agent used as an irrigant or an intracanal medication.

“…This model provided a justified surface area for studying the diffusion of ions through dentinal tubules of the root and reduced differences between samples. Moreover, to ensure that hydroxyl ions and calcium ions diffused to the external root surface through the dentin at the simulated root resorption cavity, the apical areas were sealed with sticky wax and double coats of nail polish were applied on the root thoroughly except the resorption fields (Caicedo et al, 2004; Viapiana et al, 2016). Although it is inconsistent whether removal of smear layer affects hydroxyl ion diffusion through dentinal tubules (Foster et al, 1993; Saif et al, 2008), this study removed the smear layer from both the instrumented intracanal walls and the external root cavities, in order to create the similarities between samples.…”

Objective: The purpose of this study was to evaluate pH and calcium ion release at the outer dentin surface of simulated external root resorption cavities after root canals obturated with bioceramic root canal sealer compared with those medicated with calcium hydroxide.Materials and Methods: Sixty extracted human single-rooted teeth were selected and instrumented. External root resorption cavities were prepared at the lingual surface of the root. The teeth were randomly divided into three groups:(1) Bioceramic sealer group, canals were obturated with gutta-percha and BioRoot sealer; (2) Calcium hydroxide group, canals were medicated with UltraCal XS;(3) Control group, canals were left empty. Thirty specimens were used for evaluation of pH at 7, 14, and 28 days (n = 10 per group) and the other 30 specimens were used for evaluation of calcium ion diffusion at 28 days (n = 10 per group).Results: Calcium hydroxide group showed the highest median pH value at all time points (7, 14, and 28 days). Both calcium hydroxide and bioceramic sealer groups showed significantly higher median pH values compared with control (p < .001).Comparing within groups, both bioceramic sealer group and calcium hydroxide group showed significantly decreased median pH over time, while the median pH of the control did not show any significant difference among Days 7, 14, and 28. Both calcium hydroxide and bioceramic sealer groups had significantly higher calcium ion release than control. Notably, bioceramic sealer group showed significantly higher calcium ion release than the calcium hydroxide group (p < .01).Conclusions: Root canals obturated with gutta-percha and bioceramic sealer showed high calcium ion levels at the simulated external root resorption cavities but did not show an extended period of alkaline pH.
