Aydinoglu, Aysu published the artcileDevelopment of Biomimetic Hydroxyapatite Containing Dental Restorative Composites, Recommanded Product: Ethyl 4-dimethylaminobenzoate, the publication is Arabian Journal for Science and Engineering (2022), 47(5), 6667-6678, database is CAplus.
The aim of the study was to evaluate the incorporation effect of biomimetic hydroxyapatite (BHA) particles on the mech. properties of exptl. dental composites. Two exptl. composites were produced from the same organic matrix, Si/Zr nanocluster, and SiO2/silane as main inorganic reinforcing fillers. 7wt% BHA was added to one of the groups to evaluate its effect on mech. properties. The BHA was also modified with 3-MPTMS to improve chem. bonding. Chem. structures and phys. properties of the fillers were identified by XRD, FTIR, XPS, TGA, SEM, BET, and Zeta-Sizer. According to ISO 4049 and DIN 50,133 the mech. properties, and to ISO 10993-5:2009 the biocompatibility was investigated. Anal. of variance (ANOVA) was used for the statistical anal. of acquired data. The BHA was synthesized by the biomimetic method in simulated body media (SBF). The SEM images of BHA/Silane particles demonstrated rod-like shapes and similar dimensions with natural hydroxyapatite present in tooth enamel. The modification by using 3-MPTMS was decreased the mean particle size of the fillers due to a lower agglomeration tendency. Moreover, the addition of small mass fractions of the BHA into the dental resins can substantially meet the ISO 4049 requirements. Consequently, the BHA was not adversely decreasing the mech. properties of the dental composites. Also, the biocompatibility of the BHA-containing composites was found better than the samples without BHA-containing composites. The incorporation of the BHA can meet the mech. requirements of dental resins and composites. Addnl., it may show regenerative properties against small lesions.
