Effect of Probiotic Mouthrinses on Surface Microhardness of Esthetic Restorative Materials.

Aim: To assess the influence of three probiotic mouthrinses on the microhardness of three esthetic materials used for teeth restorations.

Materials And Methods: Thirty specimens of each material: conventional glass ionomer cement (GIC), resin-modified glass ionomer, and resin composite were randomly assigned to three groups. Surface microhardness was measured at baseline.

The Fit Accuracy of Removable Partial Denture Metal Frameworks Using Conventional and 3D Printed Techniques: An Study.

Aim: To evaluate the accuracy of removable partial denture (RPD) metal frameworks fabricated by the conventional lost-wax (CLW) technique and those made by the selective laser melting (SLM).

Materials And Methods: A dentoform of a mandibular Kennedy class III, modification 1 dental arch were surveyed, and rest seats were prepared on the abutment teeth. The dentoform was then duplicated into a metal die which was used as a reference model.
