dens invaginatus is a rare developmental anomaly of teeth with complex root canal system morphology. the present case describes a peg shape maxillary lateral incisor with dens invaginatus (oehlers type ii), necrotic pulp, and an associated large periradicular lesion. nonsurgical endodontic treatment was performed with the aim of removing the blind sac with diamond bur under the use of operating...

The purpose of this study was to evaluate in vivo the response of the periradicular tissues after endodontic treatment and root filling with Epiphany/Resilon (Penntron Clinical Technologies, LLC, Wallingford, CT) or gutta percha and new Sealapex (SybronEndo, Glendora, CA) in dogs' teeth with or without coronal restoration. Teeth without coronal restorations were used to assess the influence of ...

Aspirating the unknown contents of a bony cavity and saline irrigation of a body wound are both basic surgical techniques. These two techniques have been combined in treating persistent periradicular pathosis in two cases. The cases demonstrate significant bony healing of extensive periradicular defects after the use of the combined procedure. Both cases were nonresponsive to nonsurgical root c...

The purpose of a root-end filling is to establish a seal between the root canal space and the periradicular tissues. As root-end filling materials come into contact with periradicular tissues, knowledge of the tissue response is crucial. Almost every available dental restorative material has been suggested as the root-end material of choice at a certain point in the past. This literature review...

Despite the good general patient acceptance, high patient comfort, safety and precision in the needle placement, exposure to radiation in computed tomography (CT)-guided spinal interventions remains a serious concern, and is often used to argue against its use. The aim of this study was to determine the technical possibilities of reducing the radiation dose in CT-guided epidural and periradicul...

Flare-ups can occur after root canal treatment and consist of acute exacerbations of an asymptomatic pulpal and/or periradicular pathologic condition. The causative factors of interappointment pain encompass mechanical, chemical, and/or microbial injury to the pulp or periradicular tissues. Microorganisms can participate in causation of interappointment pain in the following situations: apical ...

Apical periodontitis, a chronic inflammatory lesion of the periradicular tissue, is caused by etiological agents endodontic origin. It considered as potent communication between microbiological factors and defense system host at interface periodontal ligament infected radicular pulp. Endodontic treatment failure often characterized existence post-treatment apical which may be persistent, recurr...

Pulpal and periradicular pathology is the common sequel following trauma to teeth severe enough cause displacement of tooth resulting in necrosis pulp as a result severing neurovascular supply near apical constriction. This case report evidenced conservative non-surgical endodontic management large periapical lesion 19-year-old young male induced due traumatic injury face.

Spinal injection procedures can be performed blindly or, more accurately, with fluoroscopic or computed tomography (CT) guidance. Radiographic guidance for selective nerve root blocks and epidural injections allows an accurate needle placement, reduces the procedure time and is more secure for the patient, especially in patients with marked degenerative changes and scoliosis, resulting in a nar...

Endodontic infections have been traditionally studied by culture methods, but recent reports showing that over 50% of the oral microbiota is still uncultivable (B. J. Paster et al., J. Bacteriol. 183:3770-3783, 2001) raise the possibility that many endodontic pathogens remain unknown. This study intended to investigate the prevalence of several uncultivated oral phylotypes, as well as newly nam...
