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 ...

When the pathological process affects dental pulp of deciduous element and causes inflammation or infection, endodontic treatment is indicated. The maintenance primary tooth important, especially in cases permanent agenesis. aim this study to report a clinical case about lower molar with furcation lesion, root resorption premolar A patient was selected at clinic FAPAC/ITPAC (Porto Nacional) – T...

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...

AIM To monitor and compare the outcome of periradicular surgery in teeth that had previously undergone surgical treatment versus teeth that were undergoing a surgical procedure for the first time. METHODOLOGY A total of 164 patients with 231 roots with previously unresolved periapical lesions were followed for up to 5 years following surgery. In all, 162 roots had received unsuccessful conven...

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...

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...
