Enhancing orthopedic outcomes: A comparative analysis of gentamicin sulphate and nanosilver in bone cement.

Background: Orthopedic surgeries frequently utilize bone cement, which can increase the risk of postoperative infections. Addressing this challenge, this study aims to enhance the mechanical, physical, and handling properties of bone cement by integrating gentamicin sulfate (GS) and nanosilver (nAg). The objective is to evaluate and compare the effects of these additives on properties such as compressive strength, flexural strength, doughing time, working time, setting time, and exothermic temperature.

Evaluation of different remineralization agents in the treatment of natural caries-affected dentin in permanent teeth.

Background: In the preventive treatment protocol, providing remineralization of the tissue in demineralized dentin caries is an important step.

Objective: In this in vitro study, the effectiveness of remineralization agents in natural caries-affected dentin (NCAD) were investigated.

Methods: Forty caries slices were prepared from permanent molar dentin with International Caries Detection and Assessment System (ICDAS 2) (Code 3).

Effects of silane-modified fillers on properties of dental composite resin.

The effect of silanization on the mechanical, chemical, and physical properties of dental composites was investigated. Silica fillers were obtained from colloidal silica solution, Ludox® HS-40 and they were silanized by using 3-methacryloxypropyl trimethoxysilane (MPTMS) in an acidic media. Mineralogical and chemical structures of unsilanized and silanized fillers were determined by using XRD and FT-IR analyses.

The precursors effects on biomimetic hydroxyapatite ceramic powders.

In this study, effects of the starting material on chemical, physical, and biological properties of biomimetic hydroxyapatite ceramic powders (BHA) were investigated. Characterization and chemical analysis of BHA powders were performed by using XRD, FT-IR, and ICP-AES. Microstructural features such as size and morphology of the resulting BHA powders were characterized by using BET, nano particle sizer, pycnometer, and SEM.
