COVID-19-associated Parotid Gland Abscess.

Background: Human infection with the SARS-CoV-2 virus has caused a pandemic characterized by a plethora of diseases, of which those affecting the internal organs and nervous system can have severe, life-threatening consequences. Among the manifestations of the disease at the viral entry site, diseases in oral mucosa adnexa are rarely reported. This case report describes a COVID-19-associated aggravating parotid gland disease.

Retrospective analysis of bacterial colonization of necrotic bone and antibiotic resistance in 98 patients with medication-related osteonecrosis of the jaw (MRONJ).

Objectives: The aim of our study was to describe microbial flora associated with MRONJ and characterize the susceptibility of pathogens to help guide an effective empiric antibiotic treatment in these patients.

Materials And Methods: A retrospective, single-center analysis was performed, using 116 bone samples from 98 patients. The bone samples were homogenized and subjected to routine culture methods.

Postoperative bleeding risk for oral surgery under continued rivaroxaban anticoagulant therapy.

Objectives: The purpose of this study was to assess the risk of postoperative bleeding complications after oral procedures performed under continued mono or dual anticoagulation therapy with rivaroxaban (and aspirin).

Methods: This retrospective single-center observational study included 52 oral procedures performed under continued oral anticoagulant therapy with rivaroxaban (20 mg/day). Among them, two procedures were performed under continued dual therapy with aspirin (100 mg/day) added to the regimen.
