An unusual case of dens invaginatus on a mandibular second molar: a case report.

The present case report describes the endodontic treatment of a type III B dens invaginatus (DI) in a three-rooted mandibular second molar since the invagination invades the root and extends apically. Clinical and cone-beam computed tomography examination of the mandibular second molar showed a broadened coronal morphology, DI, a third root, periapical radiolucency, and compression of a distal root canal by the invagination, which developed an atypical semilunar shape. The tooth was diagnosed with pulpal necrosis, symptomatic apical, and peri-invagination periodontitis.

Activation of Irrigants in Root Canals with Open Apices: A Narrative Review.

Performing endodontic treatment on a tooth with an immature apex can be challenging due to the risk of irrigant extrusion beyond the apex. This narrative review investigates the over-apex extrusion of activated irrigants in teeth with open and immature apices and aims to provide crucial insights for practice and research. Two hundred fifty-two results were found from the electronic search.

The Impact of Assessment of Nurses' Experiences in Thoracic Surgery in Onco-Hematological Patients.

Nowadays, Thoracic Surgery is technologically advanced; therefore, it also focuses its attention on nursing care. The aim of the study is to evaluate the effect of the assessment of a dedicated team of nurses (DTN) in all onco-hematological patients undergoing VATS lobectomy for lung cancer on the outcome of the patient, preventing pressure injuries, reducing perioperative stress, duration of operations, complications, and hospital stay times. We performed a single-center observational retrospective study, including 31 DTN and 760 onco-hematological patients who underwent thoracic surgery between 30 October 2018 and 30 June 2023 at "Vanvitelli" University of Naples.

Pulp regeneration treatment using different bioactive materials in permanent teeth of pediatric subjects.

Background And Objectives: The present systematic review aims to assess the success rate of the pulp regeneration treatment, according to the American Association of Endodontists (AAE) criteria, using different bioactive materials in permanent teeth of pediatric subjects (6-17 years of age).

Materials And Methods: The study protocol was registered on PROSPERO and adhered to the Preferred Reporting Items for Systematic Reviews and Meta-analyses statement. The question formulation was accomplished using the PICO model, and an electronic search was carried out on Scopus, MEDLINE/PubMed, Web of Science, and Cochrane databases till April 1, 2023.

Influence of Bioceramic Cements on the Quality of Obturation of the Immature Tooth: An In Vitro Microscopic and Tomographic Study.

The present in vitro study focuses on the filling ability of three different bioceramic cements with or without the addition of a bioceramic sealer in an open apex model on the marginal apical adaptation, tubule infiltrations, and void distributions as well as the interface between the cement and the sealer materials. To this end, sixty mandibular premolars were used. MTA-Biorep (BR), Biodentine (BD), and Well-Root Putty (WR) were used to obturate the open apex model with or without the addition of a bioceramic sealer, namely TotalFill BC sealer™ (TF).
