“…In order to avoid being washed out, the ideal setting time should be reduced. However, an extremely reduced setting time may result in difficult handling during application of the material (4,18). According to the manufacturer, the final setting time of white MTA-Angelus is 15 min.…”

“…Several studies have shown that both MTA and PC present similar physicochemical and biological properties (2)(3)(4)(5). PC has been proposed as an alternative material to MTA, but its major disadvantage is that it does not achieve the radiopacity level required to be distinguished from the surrounding anatomical structures, thus requiring the addition of a radiopacifying agent prior to its use as an endodontic material (6).…”

“…Prognosis in these cases is improved when the transplanted tooth has a partially developed root, because it will allow for pulp revascularization and proper development of the root with closure of the foramen (3)(4)(5), thereby reducing the likelihood of requiring endodontic therapy with its associated additional costs and possible complications.…”

Objective: To propose bismuth carbonate, a radiopacifying agent, as a new endodontic root repair material that was added to Portland cement (PC) at 2 wt%, 5 wt%, 10 wt% and 15 wt%, and physicochemical and biological properties of each formulation were evaluated in comparison to MTA-Angelus. Methods: Mixed and powder samples were analysed by scanning electron microscopy (SEM) and X-ray power diffraction (XRD), and the semiquantitative constitution of the powder was determined by energy-dispersive spectrometer (EDS). Setting time was evaluated by Vicat needle and radiopacity analysed with digital X-ray. The pH of all tested materials was observed after immersion in water for 3, 24, 48, 72 and 168 h (or 7 days). Solubility and calcium release were measured after immersion in water for 24 h. A multiparametric assay XTT-NR-CVDE was used to evaluate the cytotoxicity of the materials in human periodontal ligament (HPDL) fibroblasts. HPDL fibroblasts were exposed to PC 15% and mineral trioxide aggregate (MTA), and the expression of proinflammatory cytokines (IL1A, IL6, IL8, TNF) and bone formation genes (ALP, COL1 , RUNX2) was evaluated by real-time PCR. Mineralisation of HPDL fibroblasts cocultured with PC, PC 15% and MTA was evaluated with Von Kossa staining. Results: PC-based groups presented more irregular and larger particles than MTA. PC and MTA showed similarities as observed by XRD and EDS. Setting time of PC-based groups was increased with the addition of bismuth carbonate. All tested materials were alkaline, and pH tended to reduce over time. All cements had solubility lower than recommended, with no difference between them (P>0.05) and showed calcium release. PC 15% had similar radiopacity when compared with MTA (P>0.05). Cell viability was higher for the tested materials than the positive control (P<0.001), but there was no difference when they were compared with negative control (P>0.05). Gene expression levels were similar for all tested groups (P>0.05). Analysed cements had positive Von Kossa staining. Conclusion: Overall, the addition of 15% of bismuth carbonate did not result in significant changes to its physicochemical and biological properties when compared with MTA, except for the setting time, and may be considered a potential substitute for MTA. Keywords: Bismuth carbonate, mineral trioxide aggregate, portland cement, root repair material INTRODUCTIONMineral trioxide aggregate (MTA) is a root repair material with Portland cement (PC) and bismuth oxide as major components (1). Several studies have shown that both MTA and PC present similar physicochemical and biological properties (2-5). PC has been proposed as an alternative material to MTA, but its major disadvantage is that it does not achieve the radiopacity level required to be distinguished from the surrounding anatomical structures, thus requiring the addition of a radiopacifying agent prior to its use as an endodontic material (6).Previous studies have shown that bismuth oxide, the radiopacifying agent in ProRoot MTA and MTA-Angelus, decrea...

“…MTA is considered the gold standard for root-end filling 7,17,21 , induces biomineralization, and is associated with favorable prognosis in endodontic surgeries. However, MTA contains bismuth oxide, which is a factor that must be taken into consideration when using this cement as a root-end filling material.…”

“…The major components of Portland cement are comparable to those of MTA, except for the radiopaque agent bismuth oxide [13][14][15] . Other similarities between the two materials include antimicrobial activity and biocompatibility 3,13,[16][17][18][19][20] . Previous studies indicate the potential viability of using Portland cement in the same applications as MTA.…”

PURPOSE:To evaluate the clinical applicability of Pozzolana Biologic Silva cement (PBS ® ) in endodontic surgery. METHODS:Persistent apical periodontitis was diagnosed in 30 teeth of 12 patients by cone-beam computed tomography (CT). All patients had 2 or 4 affected teeth and underwent endodontic surgery with root-end filling. Patients with 2 affected teeth had one tooth (control) treated with mineral trioxide aggregate (MTA-Angelus ® ) as a root-end filling material, and the other tooth treated with PBS (experiment). When the patient had four affected teeth, two of them were treated with MTA and two with PBS. Six months after surgery, all patients were assessed by CT scan. Between-group comparisons of measurements were performed using the Wilcoxon test. RESULTS:Periradicular tissue regeneration was observed in all cases. Significant within-group differences in long axes of the lesion were found in the bucco-palatal direction (PBS group, p=0.0012; MTA group, p=0.024) and coronal-apical direction (PBS group, p=0.0007; MTA group, p=0.0015) between pre-and postoperative measurements. CONCLUSIONS:Pozzolana Biologic Silva cement can be used in the treatment of persistent periradicular lesions. The clinical use of PBS as a root-end filling material may be an alternative to MTA. PBS has additives, which provide enhanced strength.
