Photodynamic therapy in the coadjuvant treatment of Sporothrix schenckii complex.

Introduction: Sporotrichosis, a zoonosis caused by animal, mainly cat, scratches or bites, is caused by fungi belonging to the Sporothrix complex. Treatment usually consists in antifungal administration, although treatment failure and hepatotoxicity reports have been noted. Alternative sporotrichosis treatment methods, such as antimicrobial photodynamic therapy (aPDT), may, therefore, be indicated.

Photodynamic Therapy as an adjunct in the Treatment of Medication-Related Osteonecrosis of the Jaw: A Case Report.

Medication-related osteonecrosis of the jaw (MRONJ) corresponds to an adverse effect of the use of drugs such as bisphosphonates and denosumab. This condition is often associated with pain, infection, purulent secretion, paraesthesia, tooth mobility and halitosis, decreasing the patient's quality of life. The management of MRONJ tends to be conservative, through the guidance of oral hygiene, antibiotic therapy and mouthwashes.

The Role of the Dental Surgeon in Controlling the Dissemination of COVID-19: A Literature Review.

As early as December 2019 in the province of Hubei, China, contamination of patients with pneumonia of an unknown etiology occurred. These patients presented with symptoms such as coughing, sore throat, malaise, diarrhea, high fever, and dyspnea. This emerging disease was named COVID-19 due to being part of the group of coronaviruses (CoVs) belonging to the subfamily , in the family and in the order.

Micro-CT analysis of dentinal microcracks on root canals filled with a bioceramic sealer and retreated with reciprocating instruments.

This study aimed to analyze the potential occurrence of dentinal defects after the removal of a root canal filling with two different sealers using Reciproc (RC) or Reciproc Blue (RB). The mesial roots of 60 mandibular molars with a Vertucci type IV configuration were selected. The samples were initially instrumented with Reciproc (R25) and then divided into the following four experimental groups according to the endodontic sealer and retreatment instrument (n = 15): BC Sealer/Reciproc (BCRC); BC Sealer/Reciproc Blue (BCRB); AH Plus/Reciproc (AHRC); and AH Plus/Reciproc Blue (AHRB).

Antibacterial Effect of Photodynamic Therapy on Root Canal Disinfection Combined with Different Irrigation Protocols.

Introduction: Photodynamic therapy (PDT) is an emerging alternative therapy to conventional endodontic treatment to optimize bacterial elimination. The aim of this study was to evaluate the antibacterial effect of PDT combined with different irrigation protocols on root canals inoculated with () .

Methods And Materials: Ninety uni-radicular human premolars were prepared and contaminated with for 4 days.

Reciproc and Reciproc Blue in the removal of bioceramic and resin-based sealers in retreatment procedures.

Objectives: To compare the remaining root canal filling material, dentin removal, apical transportation, and apical extrusion of debris after the retreatment of canals filled with bioceramic or resin-based sealers using the Reciproc or Reciproc Blue instruments.

Materials And Methods: Sixty mandibular molars with severely curved mesial roots were selected. The samples were initially instrumented with Reciproc (R25) and then divided into four experimental groups according to the endodontic sealer and retreatment instrument (n = 15): BC Sealer/Reciproc (BCRC), BC Sealer/Reciproc Blue (BCRB), AH Plus/Reciproc (AHRC), and AH Plus/Reciproc Blue (AHRB).

Quantitative analysis of apically extruded bacteria following preparation of curved canals with three systems.

This study compared the amount of apically extruded bacteria following preparation of curved root canals using two continuously rotating multifile and one reciprocating single-file systems. Mesiobuccal canals from maxillary molars were contaminated with Enterococcus faecalis and divided into three groups according to the instrumentation system: Reciproc (R25 instrument, 25/.08), BT-RaCe (10/.
