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 ...

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...

This study intended to examine histologically root canal-treated teeth evincing apical periodontitis lesions and correlate the findings with clinical observations. Specimens were obtained from 24 patients (12 asymptomatic and 12 symptomatic) by extraction or endodontic surgery and consisted of roots or root tips and the associated pathologic lesion. Specimens were processed for histologic analy...

BACKGROUND AND OBJECTIVES Ultrasound-guided cervical periradicular steroid injection (US-CPSI) is an attractive alternate to conventional C-arm guided transforaminal epidural injection for treatment of cervical radicular pain. We compared the technical differences and clinical outcomes between these two techniques. METHODS Following ultrasound-guided needle placement, the extent of contrast m...

Aim: To evaluate the diagnostic accuracy of panoramic radiography (PAN) for identification infectious foci tooth and periradicular bone before definitive chemo-radiotherapy treatment oropharyngeal cancer, using multislice spiral computed tomography (MSCT) imaging as reference standard. Materials methods: 50 patients with cancer who had performed both pre-treatment MSCT PAN were retrospectively ...

Inflammatory external root resorption is one of the major complications after traumatic dental injury. In this case report, we describe treatment of a maxillary central incisor affected by severe, perforating external root resorption. An 18-year-old patient presented with a previously traumatized, root-filled maxillary central incisor associated with pain and sinus tract. Radiographic examinati...

A problem that an endodontist can encounter during the course of root canal treatment is pain and swelling or both in the form of flare-ups. The causes for this flare-up are numerous which include mechanical, chemical, microbial injury to the pulp or periradicular tissues, whereby an acute periradicular inflammation results. This situation can be prevented by selection of instrumentation techni...
