Evaluation of different surface treatments on the bond strength of CAD/CAM PMMA denture teeth to heat-polymerized acrylic denture base.

This in vitro study aims to evaluate various surface treatments on the shear bond strength and failure mode of CAD/CAM PMMA teeth to the heat-polymerized acrylic denture base. The study sample consisted of 100 teeth that were divided equally into five groups: Group 1: denture artificial teeth (control), Group 2: PMMA teeth without surface treatment, Group 3: PMMA teeth with MMA etching, Group 4: PMMA teeth with sandblasting (aluminum oxide particles), and Group 5: PMMA teeth with perpendicular grooves. The shear bond strength test was performed using a universal testing machine and the failure mode was recorded.

The Use of Opioids and Pain Medications in the Management of Postoperative Pain in Total Knee Arthroplasty Patients: A Retrospective Study.

Purpose: The opioid crisis amplified the concern for the appropriate use of opioids. Our study aims to investigate the pain levels and amount of opiates needed during the first three days following total knee arthroplasty (TKA), whereby Drug Enforcement Administration (DEA) Schedule II oral opiates are not available.

Methods: A year-long retrospective review of adult patients who underwent TKA was conducted.
