Article Abstract
Aims: The study aimed to evaluate and compare the efficacy of xylene in dissolving newer bioceramic sealers versus an epoxy resin-based sealer during endodontic retreatment.
Subjects And Methods: Comparing AH Plus to gutta-percha (GP) and CeraSeal (Meta Biomed), Prashanti Bioceramic Sealer, and MTA-Fillapex (Angelus), a total of 72 ( = 18) extracted human permanent teeth with a single root and a single canal were prepared to size F3 and obturated. The ProTaper Universal Retreatment technology was then used to retreat the canals. The percentage volume of remaining filling material was determined by measuring the amount of residual material following retreatment using cone-beam computed tomography.
Statistical Analysis Used: The Tukey's post hoc test and one-way ANOVA were used to analyze the data.
Results: Dissolving sealers with xylene showed varying degrees of efficiency. The results showed statistically significant difference between resin sealer and bioceramic sealers but no statistical difference among bioceramic sealers in the amount of residual after retreatment ( < 0.05). MTA Fillapex had the greatest retrievability, whereas AH Plus had the lowest.
Conclusions: Bioceramic sealers were more easily dissolved by xylene than epoxy resin-based sealers. The variability among bioceramic sealers suggests that their composition significantly influences their retreatability to consider in endodontic retreatment planning.

Background: Advanced materials and techniques are used to successfully manage the apexification of immature teeth with open apices. The use of mineral trioxide aggregate (MTA), bioceramic sealers, and sodium hypochlorite (NaOCl), combined with internal heating and ultrasonic activation, ensures that canals are cleaned, disinfected, and sealed properly. Magnification devices, such as dental operating microscopes (DOM), provide precise visualization for accurate material placement, while the micro apical placement system ensures void-free MTA delivery.

Objectives: This study aimed to evaluate the cytotoxicity and osteogenic potential of three sealers, including a strontium silicate-based sealer, C-Root SP (C-R), and two calcium silicate-based sealers, iRoot SP (i-R) and AH Plus Bioceramic Sealer (AHPbcs), compared with AH Plus (AHP) on MC3T3-E1 pre-osteoblasts.
Materials And Methods: Standardized sealer discs were eluted in a culture medium to assess cytotoxicity using the CCK-8 assay at various dilutions (1:1, 1:2, 1:5, and 1:10). Osteogenic differentiation was evaluated by culturing cells in osteogenic medium supplemented with 1:5 diluted sealer extract.

Objective: This study examined how system-matching gutta-percha (GP) cones in conjunction with calcium silicate-based sealers (CSBS) affect the sealing quality of canals prepared with variable taper nickel titanium (NiTi) files, using confocal laser scanning microscopy (CLSM) and micro-computed tomography (micro-CT).
Materials And Methods: Forty-eight extracted human mandibular premolars were instrumented using the ProTaper Ultimate and divided into four groups based on GP cone (system-matching vs. non-matching) and sealer type (PlanB vs.
