Oral health-related quality of life after rehabilitation with maxillary obturators: A comparison of patients with maxillectomy defects associated with cancer and post-COVID-19 mucormycosis.

Statement Of Problem: Maxillectomy alters function and esthetics, negatively affecting oral health-related quality of life (OHRQoL). OHRQoL has been assessed after prosthetic rehabilitation in patients with maxillectomy associated with cancer. However, OHRQoL studies after prosthetic rehabilitation in patients with coronavirus disease 2019 (COVID-19) associated mucormycosis are lacking.

Effect of Alcohol and Tea on Solubility of Soft-liner and Polymethyl Methacrylate Resin: An In Vitro Study.

Aim: To evaluate solubility of soft denture liner material and acrylic denture base resin when stored in 8% and 50% concentration of alcohol and tea(with milk and green tea) at an interval of 4,7,11 and 15 days.

Materials And Methods: An in vitro study wasdone on 75 standardized samples in disk form (15 mm × 2 mm), each for soft-liner and acrylic denture base resin. Samples were divided into 5 groups (15 per group/per material) and stored in distilled water (A), 8% alcohol (B), 50% alcohol (C), tea with milk (D) and green tea (E).

Comparison of the flexural strength of polymethyl methacrylate resin reinforced with multiwalled carbon nanotubes and processed by conventional water bath technique and microwave polymerization.

Purpose: This study was done to compare the flexural strength of polymethyl methacrylate resin reinforced with multiwalled carbon nanotubes (MWCNTs) and processed by conventional water bath technique and using microwave energy.

Materials And Methods: A total of 180 acrylic resin specimens measuring 65 mm × 10 mm × 2.5 mm were fabricated, with conventional water bath groups and microwave group having ninety specimens each.
