Influence of Filler Particle Sizes on the Physical Properties of Bulk-Fill Composites Compared to Conventional Composites.

Introduction: Filler size affects how the material is coated and finished, while filler stacking affects how strong the material is, how flexible it is, how resistant it is to wear, and how much it shrinks when it polymerizes. The purpose of this research was to compare micro-hybrid, nano-composite, and bulk-fill composites with respect to their compressive strength, diametric tensile strength, and flexural strength.

Materials And Methods: To organize the samples according to International Organization for Standardization (ISO) 4049 and American Dental Association (ADA) detail number 27, we used a custom-made Teflon mold.

Antibacterial Efficacy of Herbal Solutions in Disinfecting Gutta Percha Cones Against .

Objective: Even when endodontic procedures are performed with the utmost care, reinfection can occur. One possible explanation is that contaminated gutta-percha cones were used in the root canals. The study's goal is to assess the antimicrobial activity and efficacy of Neem, Turmeric, and Calotropis Procera in disinfecting gutta percha cones prior to obturation.

Evaluation of Remineralization Seen in Dentin Related to Ceramic Restorations.

Background: Recently, the caries management had shifted from extension for prevention to early detection and remineralization of remaining tooth structure using noninvasive techniques.

Aim: The present trial was carried out to assess the effect of adding mono-n-Dodecyl phosphate as a surfactant to ceramic on remineralization of dentin.

Materials And Methods: The 32 teeth were divided into the following four groups randomly ( = 8 each group) - Group I: cavities not restored, Group II: Restored with ceramic, Group III: restored with ceramic and 2% mono-n-Dodecyl phosphate, and Group IV: restored with ceramic and 5% mono-n-Dodecyl phosphate.

Quantitative Evaluation of Apically Extruded Debris in Root Canals prepared by Single-file Reciprocating and Single File Rotary Instrumentation Systems: A Comparative Study.

Background: Prevention of the debris from extruding to the periapical region is an important aspect to be taken care of as its extrusion can result in pain, periapical inflammation, and delayed healing owing to the presence of highly infective components in the debris.

Aim: The present trial was aimed to compare and assess the amount of debris extruded apically using the single-file reciprocating system - WaveOne GOLD and single file rotary system - OneShape in root canal preparations .

Materials And Methods: Thirty mandibular premolars were divided into two groups (15 samples each) prepared with a single-file reciprocating system - WaveOne GOLD and single-file rotary system - OneShape.

Antiviral dynamics and sex differences of zidovudine and lamivudine triphosphate concentrations in HIV-infected individuals.

Objectives: Nucleoside analog reverse transcriptase inhibitors (NRTI) are used in virtually all anti-HIV regimens. Clinical response depends on the intracellular formation of the pharmacologically active triphosphate moiety. Our objective was to quantify the pharmacological characteristics of zidovudine and lamivudine triphosphate in HIV-infected individuals.
