Article Synopsis
- * The patient's dental issues included a fractured tooth and signs of infection, leading to the decision to use a guided endodontic approach due to the complexity of accessing the canal orifices.
- * After utilizing cone-beam computed tomography and 3D printing technology to create a treatment template, successful endodontic treatments were performed, with a positive outcome observed during a 1-year follow-up.
Introduction: This study aimed to assess the fracture resistance of mandibular first molars after preparation with 3 different access cavity designs and 2 rotary systems using finite element analysis.
Methods: Six 3-dimensionally printed mandibular first molars simulating natural teeth received traditional, conservative, and ultraconservative (truss) access cavity preparations. The root canals in each group were instrumented with either XP-Endo Shaper (FKG Dentaire, La Chaux-de-Fonds, Switzerland) or TruNatomy (Dentsply Sirona, Ballaigues, Switzerland) rotary files.
Article Synopsis
- This study evaluated the quality and quantity of bone from the mandibular ramus for potential use in autologous bone grafting.
- Researchers assessed various parameters using CBCT scans and applied statistical methods to analyze the data collected from 52 women and 32 men aged 21 to 70.
- Findings showed that while bone volume and density varied, there was a significant decrease in bone quality related to aging, with the results indicating that both volume and density are not influenced by sex.
