Postoperative pain after single-visit root canal treatment or vital pulp therapy: A systematic review and meta-analysis.

Background: This systematic review aimed to investigate whether vital pulp therapy and root canal treatment (RCT) promote different postoperative pain.

Studies Reviewed: The authors searched PubMed, Cochrane Library, Embase, and Latin American and Caribbean Health Sciences Literature databases for studies published through June 30, 2022. The authors included randomized clinical trials if they reported on the assessment of postoperative pain after direct pulp capping, partial pulpotomy, pulpotomy, or single-visit RCT.

Cytotoxic, migration, and angiogenic effects of intracanal irrigants on cells involved in revascularization of immature teeth.

Objective: To evaluate protocols of root canal irrigation and dentin pretreatment in a cell culture model simulating immature teeth. Cytotoxic, migration, and angiogenic effects of Sodium hypochlorite associated with EDTA (NaOCl/EDTA), NaOCl associated with Smear Clear (NaOCl/SC), and QMix were compared.

Design: Three roots of mandibular first premolars had their length and root canal diameter standardized.

Cytotoxic, Migration, and Angiogenic Effects of Photodynamic Therapy and Photobiomodulation Associated with a Revascularization Protocol.

Introduction: This study evaluated photodynamic therapy (PDT) and photobiomodulation therapy (PBM) as adjuncts to pulp revascularization using cultures of apical papilla cells (APCs) and endothelial cells (HUVECs).

Methods: The root canal and apical foramen of 2 mandibular first premolars were enlarged to simulate immature teeth. The canal of 1 tooth was filled with 1 mL 0.

Noninvasive positive pressure ventilation delivered by helmet vs. standard face mask.

Objective: This bench and human study compared large and small helmets with face mask (FM) for delivery of noninvasive positive pressure ventilation.

Design: A lung simulator was employed, and the human study involved six healthy subjects. We evaluated a continuous high-flow (CPAPHF), low flow (CPAPLF), ventilator (CPAPVENT) CPAP, and pressure support ventilation (PSV 10 and 20 cmH2O).

Non-invasive ventilation delivered by conventional interfaces and helmet in the emergency department.

Non-invasive positive pressure ventilation is increasingly used as a first-line treatment for respiratory failure. Non-invasive positive pressure ventilation can reduce the complications of endotracheal intubation such as barotrauma, nosocomial infections and the need for sedation. Non-invasive positive pressure ventilation has been shown to reduce the rate of endotracheal intubation in acute cardiogenic pulmonary oedema (27%), in chronic obstructive pulmonary disease (21%), and in acute respiratory failure (17%).
