Resin-based dental pulp capping restoration enclosing silica and portlandite nanoparticles from natural resources.

Natural-based materials represent green choices for biomedical applications. In this study, resin pulp capping restoration enclosing strengthening silica and bioactive portlandite nanofillers were prepared from industrial wastes. Silica nanoparticles were isolated from rice husk by heat treatment, followed by dissolution/precipitation treatment.

Efficacy of photobiomodulation using diode laser 650 nm combined with nano-cellulose and nano-amorphous calcium phosphate in bone healing of rabbit tibial defects assessed by H&E staining and computed tomography.

Background: The purpose of the current study was to evaluate the effect of Diode LLLT 650 nm, TEMPO oxidized Nano-fibrillated cellulose mixed with Nano-Amorphous calcium phosphate, and their combination on bone healing in rabbit tibia using H&E staining and computed tomography.

Methods: Eighteen adult male New Zealand rabbits were selected, two circular bone defects were created in each tibia, resulting in four bony defects in each rabbit, representing the four tested groups; group A (negative control), group B (filled with mineralized nano-cellulose), group C (combination), group D (laser). Animals were euthanized after two weeks and one month, defects were assessed by CT for bone density, then histological samples were examined by H&E stain.

Effect of silver diamine fluoride/potassium iodide treatment on the prevention of dental erosion in primary teeth: an in vitro study.

Introduction: Dental erosion has a great effect on oral health, when diagnosed it is irreversible, this sets the importance of different preventive measures being investigated against dental erosion.

Aim: This in vitro study aims to evaluate the effectiveness of silver diamine fluoride and Potassium iodide (SDF-KI) in comparison to casein phosphopeptide-amorphous calcium phosphate fluoride (CPP-ACPF) varnish, sodium fluoride (NaF) varnish, silver diamine fluoride (SDF) alone and deionized water as a control group in the prevention of dental erosion in primary teeth and assessing its staining effect.

Materials And Methods: Forty deciduous teeth enamel specimens were randomly allocated into the five study groups.

Direct-acting antiviral regimens in Egyptian patients with chronic hepatitis C virus infection: A real-world single-center experience.

Background And Study Aims: Chronic hepatitis C virus (HCV) infection has always been identified as a major health threat and a potential cause of liver cirrhosis, portal hypertension, and other associated problems. The introduction of direct-acting antiviral agents (DAAs) has represented a paradigm shift in HCV management. In this study, we aim to observe the rate of sustained virologic response (SVR12) in a large scale of patients at a single center as well as record the post-treatment changes in the hematologic, hepatic, and renal biochemical profiles.

EFFICACY OF HEMOSTATIC AGENTS IN ENDODONTIC SURGERY: A SYSTEMATIC REVIEW AND NETWORK META-ANALYSIS.

Objective: Adequate hemostasis is a critical step in endodontic surgery. It facilitates the procedure and affects the success and prognosis of the operation. This systematic review and network meta-analysis (NMA) aimed to systematically assess the efficacy of hemostatic agents in endodontic surgery and to identify the most effective ones.
