Article Synopsis
- The study assessed how different methods of agitation for dental irrigants affect the temperature of the tooth root surface, using nine human lower premolars as subjects.
- Temperature measurements were taken at three sections of the root (middle, cervical, apical) using three agitation methods: ultrasonic tips, Easyclean tips, and XP-endo Finisher files.
- Results showed that the ultrasonic agitation method raised temperatures more than the other methods, but all remained below 47ºC, indicating safety for surrounding periodontal tissues.
Introduction: The aim of this study was to analyze the contribution of bone marrow-derived cells (BMDCs) to reparative dentinogenesis using bone marrow transplantation (BMT) and pulp capping as an in vivo model.
Methods: A chimeric mouse model was created through the injection of BMDCs expressing green fluorescent protein (GFP+ BMDCs) from C57BL/6 GFP+ transgenic donor mice into irradiated C57BL/6 wild-type recipient mice (GFP- mice). These GFP- chimeric mice (containing transplanted GFP+ BMDCs) were subjected to microscopic pulp exposure and capping with white mineral trioxide aggregate (n = 18) or Biodentine (Septodont, St Maur-des-Fossés, France) (n = 18) in the maxillary first molar.
Objective: Knowledge of internal anatomy of the teeth is of great importance in endodontics, leading to success in root canal therapy (RCT). The aim of this study was to assess the root anatomy and canal configuration of maxillary molars in a Brazilian subpopulation using tomographic images using a voxel size of 125 μm.
Materials And Methods: This in vivo retrospective study assessed 651 cone-beam computed tomographic scans from 328 maxillary first molars and 323 maxillary second molars.
