AIM: Mineral trioxide aggregate (MTA) was associated to Aloe vera to verify the coadjutant action of that medicinal plant in the bone neoformation process in tibia of rats.MATERIAL AND METHOD: 36 male rats (Rattus norvegicus) were used, divided into two groups of 18 rats each. Two circumferential bone defects with approximately 5 mm in diameter were made on the right tibia of each animal: the upper defect was filled with blood coagulates in both groups to serve as experimental control and the lower defect was filled with MTA and Aloe vera in experimental (group E1) and MTA and distilled water in experimental (group E2). Seven, 15 and 30 days after surgery, six animals from each group were euthanized and the right tibia of each animal was removed for histological analysis.RESULT: Histologically, experimental group E1 presented better results for the two variables, inflammation [at seven days (p=0.045)] and bone formation [at seven days (p=0.018) and 30 days (p=0.034)], compared to the E2 group.CONCLUSION: The association of MTA and Aloe vera showed potential to reduce the effects of the inflammatory cascade and promote bone neoformation making it to a promising proposal for future use in endodontic therapy.

Comparison of root canal filling quality by mineral trioxide aggregate and gutta percha cones/AH plus sealer

et al. 2016

The aims of this study were to evaluate the quality of canal filling using mineral trioxide aggregate (MTA) and gutta-percha (GP) in root canals, and to investigate the differences in the percentage of voids between mesial and distal canals by using microcomputed tomography. Twenty-two extracted human mandibular molars were instrumented using rotary files. Two teeth without canal fillings served as negative controls, and the other teeth were obturated with either ProRoot ® MTA or gutta-percha and AH Plus ® sealer. Obturated teeth were scanned with microcomputed tomography, and the percentage of voids (V %) was calculated. These specimens were also examined under a scanning electron microscope. The MTA group showed a significantly higher V % than the GP groups (p<0.05). The mesial canal groups showed significantly higher V% than did the distal canal groups (p<0.05). In orthograde filling, MTA exhibited significantly lower filling quality than did GP.

“…Although earlier studies recommended the use of a Ca(OH)2 prior to MTA placement, recent studies report that the initial use of Ca(OH)2 paste was not necessary for apexification to occur, and it has shown to be strongly related to the extrusion of MTA and formation of barriers beyond the limits of the root canal walls. 3 The major problem in cases of a wide open apex is the need to limit the material to the perforation, thus avoiding the extrusion of a large amount of material into the periodontal tissue [18,19]. A large volume of the extruded material may set before it disintegrates and get resorbed.…”

“…A large volume of the extruded material may set before it disintegrates and get resorbed. This might result in the persistence of the inflammatory process, which may complicate or even prevent repair of the tissue [18,19] Using a matrix avoids the extrusion of the material into the periodontal tissues, reduces leakage in the sealing material and allows favorable response of the periodontal tissues. As mentioned before, a number of materials are available for the formation of the apical matrix.…”
