Objectives: The purpose of this study was to evaluate and compare the cytotoxic effects of ProRoot MTA and DiaRoot BA, a bioceramic nanoparticulate cement, on subcutaneous rat tissue. Study Design: Fifty Sprouge Dawley rats were used in this study. Polyethylene tubes filled with ProRoot MTA and DiaRoot BioAggregate, along with a control group of empty, were implanted into dorsal connective tissue of rats for 7, 15, 30, 60, and 90 days. After estimated time intervals the rats were sacrificed. The specimens were fixed, stained with hematoxylin and eosin, and then evaluated under a light microscope for inflammatory reactions and mineralization. Results: All groups evoked a severe to moderate chronic inflammatory reaction at 7 and 15 days, which decreased with time. Both the MTA and BioAggregate groups showed similar inflammatory reactions, except at 90 days when MTA showed statistically significant greater inflammation (p>0.05). The MTA group showed foreign body reaction at all times. Compared to BioAggregate, MTA showed significantly more foreign body reaction at 60 and 90 days (p<0.0001). After 30 days foreign body reaction of BioAggregate decreased significantly. Both MTA and BioAggregate groups showed similar necrosis at 7 and 15 days (p=0.094 and p=0.186 respectively). No necrosis was observed after 15 days. Similarly there was no fibrosis after 30 days for both MTA and BioAggregate groups (p>0.05). Conclusions: Since DiaRoot BioAggregate showed significantly better results than MTA, we can conclude that it is more biocompatible. However, further studies are required to confirm this result.

To investigate the effect of accelerated-set mineral trioxide aggregate (MTA) on the proliferation and odontoblastic differentiation of human dental pulp cell niches (DPSC).
Mineral trioxide aggregate (MTA) has been successfully used in clinical applications in endodontics. However, little is known about the involvement of Wnt/β-catenin signaling in human dental pulp cel...

Background. This in vitro study compared the effects of mineral trioxide aggregate (MTA), calcium enriched mixture(CEM) cement, Biodentine (BD) and octacalcium phosphate (OCP) on the viability of huma...
Objective. The aim of this in vitro study was to evaluate the long-term fracture resistance of simulated human immature permanent teeth filled with BioAggregate™ (BA), mineral trioxide aggregate (MT...
This prospective clinical randomized controlled trial is established to compare the clinical, radiographic, and histological treatment outcomes between MTA and FC in pulpotomized human pri...
A new Endodontic Cement (NEC) is being compared with mineral trioxide aggregate in pulpotomy of primary molars.
Comparison of clinical and radiographic success between Mineral Trioxide Aggregate and Ferric Sulfate pulpotomies for primary molars. Recall appointments are completed 6 months, 9 months a...
This prospective study compares the use of indirect pulp therapy and mineral trioxide aggregate pulpotomy for pulp therapy of the primary molar with dental caries approaching the pulp.
Traumatic tooth injuries are common in children and adolescents, and often result in pulpal necrosis and the development of periapical lesions. Treatment of traumatized teeth with endodont...
Endodontic procedure performed to induce TOOTH APEX barrier development. ROOT CANAL FILLING MATERIALS are used to repair open apex or DENTAL PULP NECROSIS in an immature tooth. CALCIUM HYDROXIDE and mineral trioxide aggregate are commonly used as the filling materials.
Neoplasms developing from some structure of the connective and subcutaneous tissue. The concept does not refer to neoplasms located in connective or soft tissue.
The outer covering of the calvaria. It is composed of several layers: SKIN; subcutaneous connective tissue; the occipitofrontal muscle which includes the tendinous galea aponeurotica; loose connective tissue; and the pericranium (the PERIOSTEUM of the SKULL).
An acute, diffuse, and suppurative inflammation of loose connective tissue, particularly the deep subcutaneous tissues, and sometimes muscle, which is most commonly seen as a result of infection of a wound, ulcer, or other skin lesions.
Water naturally or artificially infused with mineral salts or gases (carbon dioxide).
Dentistry is the study, management and treatment of diseases and conditions affecting the mouth, jaw, teeth and their supporting tissues (Oxford Medical Dictionary) The work of a dentist ranges from regular patient check-up to orthodontics and surgery....
