Efficacy of different irrigant activation devices in removing dentin debris from an artificial isthmus connecting curved canals.

The aim of this study was to evaluate the debridement efficacy of sonic irrigation (EDDY; VDW, Munich, Germany and EndoActivator; Dentsply-Sirona, Ballaigues, Switzerland) and ultrasonically activated irrigation (Irrısafe; Satelec Acteon, Merignac, France) in a simulated canal isthmus connecting curved canals. Transparent resin blocks were produced containing two curved canals connected with an isthmus. The isthmus was then filled with dentin debris.

A prospective clinical study investigating the effectiveness of partial pulpotomy after relating preoperative symptoms to a new and established classification of pulpitis.

Aim: To prospectively investigate the outcome of partial pulpotomy after 1 year, using a hydraulic calcium silicate cement (HCSC) on symptomatic cariously exposed pulps in adult teeth. To compare the traditional American Association of Endodontists (AAE) pulpitis classification with the recently proposed Wolters classification system in predicting the likelihood of treatment failure.

Methodology: Sixty-two symptomatic adult teeth with deep and extremely deep carious lesions were classified according to the Wolters (mild/moderate/severe pulpitis) and the traditional pulpitis classification (reversible/irreversible pulpitis).

Dental Practice after COVID-19 Pandemic: Analysis of Italian Guidelines and Current Literature to Propose Appropriate Protocols for Dental Practices.

On March 11, 2020, WHO declared COVID-19 a pandemic. This disease is caused by SARS-CoV-2, a virus that can be spread by symptomatic or asymptomatic carriers through contact, droplets and airborne transmission. Because of the transmission routes of this virus, dental treatments are considered "high risk" procedures, both for patients and operators.

The management of deep carious lesions and the exposed pulp amongst members of two European endodontic societies: a questionnaire-based study.

Aims: To investigate and compare views on management of deep caries and the exposed pulp by Endodontic Society members in Ireland (Irish Endodontic Society [IES]) and Italy (Accademia Italiana di Endodonzia [AIE]). Further aims were to investigate the influence of patient-related factors (age, symptoms) and operator-related factors (material choice, antibiotics) on management.

Methodology: A structured online questionnaire containing two cases (an 18- and 45-year-old) and two scenarios (± mild symptoms), including history and radiograph, was sent to IES and AIE members.
