Introduction: In the COVID-19 pandemic scenario, in addition to pathogenesis of SARS-CoV-2, microbial coinfection increases difficulties diagnosis, treatment, prognosis COVID-19, as well it can worsen comorbidities and affect risk life patients. has had a profound impact on dentistry. endodontic management protocol was suggested. Objective: To present importance effectively performing asepsis c...

AIM To investigate the chemical interaction of calcium hydroxide with the antibiotics demeclocycline calcium in Ledermix Paste and clindamycin hydrochloride in Odontopaste. METHODOLOGY Validated methods were developed to analyse the interaction of calcium hydroxide in two forms, Pulpdent and calcium hydroxide powder, with the two antibiotics. High-performance liquid chromatography (HPLC) was ...

Introduction Hydroxyl ion release from calcium hydroxide is responsible for the key attributes of broad spectrum antimicrobial activity, penetration into biofilms, inhibition of endotoxins, and dissolution of organic tissues.1,2 The maximum solubility of calcium hydroxide in water at 25C is only 0.159 g/100mL (0.16%), and this reduces to 0.140 g/100 mL (0.14%) at 40C, with an accompanying decre...

OBJECTIVE The purpose of this study was to evaluate the efficacy of auxiliary chemical substances and intracanal medications on Escherichia coli and its endotoxin in root canals. MATERIAL AND METHODS Teeth were contaminated with a suspension of E. coli for 14 days and divided into 3 groups according to the auxiliary chemical substance used: G1) 2.5% sodium hypochlorite (NaOCl); G2) 2% chlorhe...

Introduction One of the most important factors for successful endodontic therapy is root canal cleaning. The difficulty involved in eliminating microorganisms, as well as their residual presence, warrants the use of root canal dressings after bio-mechanical preparation. Aim The aim of the study was to compare the diffusion ability between nonalcoholic calcium hydroxide-propolis paste, calcium...
