Evaluation of a new 3D-printed tooth model allowing preoperative ICDAS assessment and caries removal.

Introduction: Teaching caries lesion management with operative care requires tooth models with highly realistic anatomical detail and caries lesions that can be assessed using ICDAS. This study aimed to develop and evaluate a new 3D-printed teeth model for ICDAS assessment and caries removal for pre-clinical hands-on education.

Methods: Printable tooth with different layers for enamel, dentin and carious lesions was designed and tested by 31 dental students.

Current strategies for conservative endodontic access cavity preparation techniques-systematic review, meta-analysis, and decision-making protocol.

Objectives: To assess related studies and discuss the clinical implications of endodontic access cavity (AC) designs.

Materials And Methods: A systematic review of studies comparing the fracture resistance and/or endodontic outcomes between different AC designs was conducted in two electronic search databases (PubMed and Web of Science) following the PRISMA guidelines. Study selection, data extraction, and quality assessment were performed.

A cross-sectional analysis of patient care pathways and profiles in a dental emergency department.

Introduction: Hospital dental emergency (DE) departments are assumed to improve access to emergency care. Patients use these facilities at night and during weekends, mainly because private care is not available at these times. However, motivation for using hospital care during office hours remain unclear.

Dental students' attitudes towards management of pain and anxiety during a dental emergency: educational issues.

Introduction: High levels of patients' pain and anxiety characterise dental emergencies. The main objective of this study was to examine the self-reported attitudes of dental students towards these parameters in emergency conditions. A secondary objective was to determine if individual parameters (gender, personal experience of dental pain, personal dental anxiety and year of study) might affect their attitudes.

Sodium Hypochlorite Accident: A Systematic Review.

Introduction: Sodium hypochlorite (NaOCl) extrusion beyond the apex, also known as "a hypochlorite accident," is a well-known complication that seldom occurs during root canal therapy. These "accidents" have been the subject of several case reports published over the years. Until now, no publication has addressed the global synthesis of the general and clinical data related to NaOCl extrusion.

Do cell phones affect establishing electronic working length?

Introduction: Patients often keep their cell phones on and nearby during root canal therapy. Cell phones release electromagnetic interference, which might disturb electronic working length measurements. The purpose of this ex vivo study was to determine the effect of a cell phone (Apple iPhone 5 [Apple, Cupertino, CA] or KP100 [LG, Seoul, Korea]) placed into direct contact with an electronic apex locator (EAL) (Dentaport Root ZX module [J Morita Corp, Tokyo, Japan] or Propex II [Dentsply Maillefer, Ballaigues, Switzerland]) on working length determination.

Implications of endodontic-related sinus aspergillosis in a patient treated by infliximab: a case report.

Introduction: Sinus aspergillosis is a potential complication after root canal therapy of antral teeth. Indeed, zinc oxide-eugenol cement overfilling in the sinus may promote fungal infection. Moreover, if sinus aspergillosis triggers chronic sinusitis with aspergilloma, it may also lead to invasive phenomena, especially for immunocompromised patients.
