OBJECTIVE To study the in vivo osteoinductive potential, bone-bonding ability (bioactivity) and bone biomineralization of current hydraulic calcium silicate cements used as graft materials and placed in contact with medullary bone. METHODS ProRoot MTA, MTA Plus and Biodentine were used to fill surgical bone defects (2-mm diameter through the entire cortical thickness to reach the medullary bo...

Abstract The endodontic revascularization may be an alternative treatment for necrotic immature teeth, however, several steps cause tooth discoloration. This study evaluated the use of three calcium silicate-based cements with different radiopacifying agents on color alteration (∆E) extracted premolars after simulation revascularization. Forty single rooted were shaped #1-6 gates Glidden drills...

The aim of this study was to determine the subcutaneous connective tissue reactions Medcem MTA and Pure Portland Cement. MTA, Cement ProRoot were placed in polyethylene tubes implanted into dorsal Sprague Dawley rats. presence inflammation, edema, necrosis, dystrophic calcification, thickness fibrous capsule formation recorded by histological examination 7, 30, 60 days after implantation proced...

It is a worthy aim to preserve the pulp vitality in teeth with immature root in order to continue the root's maturation. Traumatic injuries and caries are two main reasons for pulp exposure in immature teeth. This article describes two vital pulp therapies on two patients, a nine-year-old boy with traumatized central tooth and a 10-year-old boy with caries exposure in a premolar tooth. Both tee...

Microstructure development and the kinetics of hydration of pure tricalcium silicate (C3S) and CaCl2-accelerated C3S pastes were investigated by performing isothermal calorimetry and in situ small-angle neutron scattering (SANS) measurements on parallel specimens during the first few days of hydration, as well as on 28-day old specimens hydrated under the same curing conditions (water/cement ra...

This study investigated the impact of calcium silicate (CS) content on composition, compressive mechanical properties, and hardness of CS cermets with Ti-55Ni and Ti-6Al-4V alloys sintered at 1200°C. The powder metallurgy route was exploited to prepare the cermets. New phases of materials of Ni16Ti6Si7, CaTiO3, and Ni31Si12 appeared in cermet of Ti-55Ni with CS and in cermet of Ti-6Al-4V with C...

Discoloration-resistant calcium aluminosilicate cement has been formulated to overcome the timely problem of tooth discoloration reported in the clinical application of bismuth oxide-containing hydraulic cements. The present study examined the effects of this experimental cement (Quick-Set2) on the viability and proliferation of human dental pulp stem cells (hDPSCs) by comparing the cellular re...
