DATA SOURCES: PubMed, Cochrane-CENTRAL, Scopus, Web of Science, Proquest, Embase, Dentistry and Oral Sciences Source, and ClinicalTrials...

Objectives: Endodontic treatment of immature teeth poses a significant challenge, especially in achieving a proper seal using traditional obturation methods. Revascularization presents itself as an alternative approach to this problem, and the application of triple antibiotic paste (TAP) has been suggested as a means to achieve disinfection during the procedure. This study aims to compare the antibacterial properties of three different antibiotic combinations to assess their effectiveness on root canal disinfection...

OBJECTIVES: While factors contributing to dental antibiotic overprescribing have previously been described, previous work has lacked any theoretical behavior change framework that could guide future intervention development. The purpose of this study was to use an evidence-based conceptual model to identify barriers and facilitators of appropriate antibiotic prescribing by dentists as a guide for future interventions aimed at modifying antibiotic prescribing. METHODS: Semi-structured interviews were conducted with dentists from the National Dental Practice Based Research Network (PBRN) exploring patient and practice factors perceived to impact antibiotic prescribing...

BACKGROUND: Different degrees of malnutrition are seen in patients with hematological malignancies. None of the approaches used to determine malnutrition risk have general acceptance. The use of the GLIM criteria developed by the Global Leadership Initiative on Malnutrition has promising results. MATERIALS AND METHODS: A total of 67 patients with leukemia, lymphoma, and multiple myeloma were included in the study. NRS-2002 (Nutritional Risk Screening-2002) was used to screen the nutritional status of the patients, and malnutrition was diagnosed and graded using the GLIM criteria in patients who were found to be at risk of malnutrition in this test...

BACKGROUND: Dental appointments offer an opportunity to evaluate a documented penicillin (PCN) allergy and determine whether the patient might be a candidate for medical reassessment of their allergy. The authors gathered feedback on the Penicillin Allergy Reassessment for Treatment Improvement (PARTI) tool, designed to enhance dentist-patient communications regarding PCN allergies. METHODS: From January 2022 through May 2023, the authors conducted a mixed-methods study, collecting focus group data from patients with PCN allergies and surveying health care workers (HCWs) regarding the PARTI tool...
