Effects of adding graphene fibers to polymethyl methacrylate on biocompatibility and surface characterization.

Statement Of Problem: Interim fixed prostheses are used provisionally to provide esthetics and maintain function until placement of the definitive prosthesis. Polymethyl methacrylate (PMMA) has been widely used as an interim material but has mechanical limitations that can be improved with the addition of nanomaterials such as graphene fibers (PMMA-G). However, studies on the biocompatibility of this material are lacking.

The Influence of the Thickness of the Materials for the Provisionalization in Minimally Invasive Restorations.

This in vitro study aimed to determine the flexural strength and modulus of elasticity of two bisacrylic resins for temporary crowns at different thicknesses, i.e., Structur 3 and Structur Premium, and to compare them with each other.

Salivary biomarkers of oxidative stress and quality of life in patients with oral lichen planus.

Aim: Lichen planus is a T cell-mediated chronic inflammatory disease of unknown etiology. The objective of the present study was to evaluate the status of oxidative stress in saliva and the anti-oxidant defense system in relation to quality of life parameters in patients with oral lichen planus (OLP).

Methods: The sample consisted of 70 patients (40 with OLP and 30 control patients).

Topical 1% oxytetracycline hydrochloride versus placebo in oral mucosa biopsy.

Background: Oral surgical procedures produce side effects such as pain and inflammation, the magnitude of which depends on the degree of tissue damage produced.

Objective: To explore the effectiveness and safety of the topical application of 1% oxytetracycline hydrochloride after biopsy of the oral mucosa.

Methods: A randomized, double-blind, placebo- and no treatment-controlled study was conducted in 90 patients with lesions needing histopathologic analysis.

Perioperative antibiotic regimen in rats treated with pamidronate plus dexamethasone and subjected to dental extraction: a study of the changes in the jaws.

Purpose: Osteonecrosis of the jaws is a well-known condition associated with long-term bisphosphonate use. This study analyzed the prophylactic effect of antibiotic treatment in Sprague-Dawley rats treated with pamidronate plus dexamethasone and subjected to oral surgery in the form of dental extraction.

Materials And Methods: One hundred twenty animals were included in a randomized prospective study.

Clinical evaluation of polyvinylpyrrolidone sodium hyaluronate gel and 0.2% chlorhexidine gel for pain after oral mucosa biopsy: a preliminary study.

Purpose: To study the symptoms of patients during the 7 days after incisional biopsy of the oral mucosa and the application of polyvinylpyrrolidone-sodium hyaluronate (Aloclair) gel or 0.2% chlorhexidine digluconate gel.

Materials And Methods: A total of 90 consecutive patients with lesions requiring histopathologic analysis were studied.
