Effect of MMP Inhibitors on Shear Bond Strength of Adhesive to Dentin after Different Drying Techniques: An Study.

Background And Objective: Instead of excessive drying or wetness, maintaining an optimal moisture level on the dentin surface may enhance the polymerization process of certain monomers. The study was intended to contrast and evaluate the effect of Matrix metalloproteinases (MMPs) inhibitors (Chlorhexidine (CHX) and Doxycycline (DOX)) on the shear bond strength (SBS) of adhesive dentin interface after different drying techniques (blotting with tissue paper (TP) and damp cotton pellet (CP)).

Materials And Methods: Ninety molars collected were split into three groups according to the materials used during the acid etching step: Group A (control): 37% phosphoric acid only; Group B: 37% phosphoric acid followed by 2% CHX; Group C: 37% phosphoric acid followed by 2% DOX.

Electrochemical dissolution and retrieval of broken NiTi endodontic files from root canal using chloride based isotonic fluids as electrolytes - An study.

Objective: The electrochemical dissolution method of instrument retrieval emphasizes on the dissolution of the instrument rather than sacrificing dentine. Most of the studies conducted for electrochemical dissolution used fluoride-containing electrolytes and were performed inside a beaker. In this study, we used chloride-based fluids as electrolytes.

A SEM Evaluation of the Permeability of Different Desensitizing Methods on Occlusion of Dentinal Tubules: An Study.

Aim: The purpose of the current research was to assess the permeability of three various desensitizing techniques on dentinal tubule occlusion using a scanning electron microscope (SEM).

Materials And Methods: For this research, 100 human sound premolar teeth that were extracted for orthodontic purposes were gathered. With the aid of a water-cooled diamond saw, the teeth were divided in a mesiodistal (vertically) orientation.

The Effects of Various Final Irrigants on the Bond Strength of Root Dentin Exposed to Chloroform: An Study.

Aim: The aim of the study was to assess the reaction of different final irrigants to the bond strength of root dentin exposed to chloroform.

Materials And Methods: Fifty extracted maxillary central incisors were selected. Working length was determined, and canal was instrumented with ProTaper rotary system (Dentsply Maillefer) till F4 file.

Evaluation of Radicular Dentin Microcracks Formation after Instrumentation with NiTi Hand and Rotary File System: A Stereomicroscopic Study.

Aim And Objective: The present study aimed to assess the formation of microcracks in root dentin post-instrumentation with nickel-titanium (NiTi) hand and rotary file system.

Materials And Methods: Totally, 80 freshly extracted mandibular premolar teeth with single roots were chosen for this study. Access opening was performed and #10 K-file was used to attain patency of canal.
