The acid resistance of Nd:YAG laser-ablated enamel surfaces was studied by evaluating crystal structure, mineral distribution, and fluorescence radiance and image in the present study. For comparison, 37% phosphoric acid etching was performed. The formation of beta-tricalcium phosphate (beta-TCP) was confirmed in the laser-ablated surface. The Ca/P ratio increased after ablation due to mineral ...

Alveolar ridge augmentation with beta-tricalcium phosphate (beta-TCP) granules, calcium phosphate cement (CPC) powder and web form of titanium fibers (TW) added to Platelet-Rich-Plasma (PRP) was histologically observed for 5 months by the experiments using the maxilla of rabbits. As a result, TW was thus found to promote the rapid bone development within a period of less than 5 months, because ...

Macroporous biphasic calcium phosphate (BCP) with channel-shaped pores was produced by a novel dual-phase mixing method. The processing route includes mixing water-based BCP slurry and polymethylmethacrylate resin; shaping in a mold; and polymerization, drying, pyrolyzing, and sintering. After comparison with two other commercial macroporous BCP materials, which were produced along different ro...

Bone is a complex porous composite structure with specific characteristics such as viscoelasticity and anisotropy, both in morphology and mechanical properties. Bone defects are regularly filled with artificial tissue grafts, which should ideally have properties similar to those of natural bone. Open cell composite foams made of bioresorbable poly(L-lactic acid) (PLA) and ceramic fillers, hydro...

Metallic biomaterials are widely used for implants and dental orthopedic applications due to their good mechanical properties. Among all these materials, 316L stainless steel has gained special attention, because of its characteristics as an implantable biomaterial. However, the Young’s modulus this metal is much higher than that human bone (~193 GPa compared 5–30 GPa). Thus, a stress shielding...

M ANY investigations have been made to establish the relationships between the concentration of salivary components and the presence of caries. In recent years considerable effort has been expanded in attempts to correlate salivary composition with the presence or absence of calculus. Since calculus is composed mainly of calcium and phosphorus as the phosphate salt, it follows from various chem...

PURPOSE The aim of this study was to evaluate the improvement of osteogenic potential of biphasic calcium phosphate (BCP) bone substitute coated with synthetic cell-binding peptide sequences in a standardized rabbit sinus model. METHODS Standardized 6-mm diameter defects were created bilaterally on the maxillary sinus of ten male New Zealand white rabbits, receiving BCP bone substitute coated...
