Comparative Evaluation of Shear Bond Strength of Tricalcium Silicate-based Materials to Composite Resin with Two Different Adhesive Systems: An Study.

Background: Establishing a strong bond between the pulp capping agent and the restorative material is crucial to the success of the procedure. Without this bond, there is a risk of bacterial infiltration into the pulp, leading to treatment failure. In the past, calcium hydroxide was commonly used for such treatments, but it faced challenges, including poor adhesion to dentin, dissolution over time, and the development of multiple tunnel defects.

Comparative Evaluation of Flexural Strength of Conventional and Modified with Chitosan, Titanium Dioxide Nanopowder and Nanohydroxyapatite: An Study.

Aim: To evaluate the effect of different add-ons on the flexural strength (FS) of glass ionomer cement (GIC).

Materials And Methods: Around 72 samples were fabricated and divided among the following six different groups: group I-control (conventional GIC-nonmodified), group II-GIC powder modified with 3% titanium dioxide (TiO) and liquid is unmodified, group III-powder modified with 10% nanohydroxyapatite (nHA) and liquid is unmodified, group IV-powder is unmodified and Liquid is modified with 10% chitosan (CH), group V-powder is modified with 3% TiO and liquid is modified with 10% CH, and group VI-powder is modified with 10% nHA and liquid is modified with 10% CH. The samples were then subjected to a three-point bending test on a universal testing machine for the evaluation of FS.

A review of bio-impedance devices.

Bio-impedance measurement analysis primarily refers to a safe and a non-invasive technique to analyze the electrical changes in living tissues on the application of low-value alternating current. It finds applications both in the biomedical and the agricultural fields. This paper concisely reviews the origin and measurement approaches for concepts and fundamentals of bio-impedance followed by a critical review on bio-impedance portable devices with main emphasis on the embedded system approach which is in demand due to its miniature size and present lifestyle preference of monitoring health in real time.
