Periapical pathosis cases were classified and the effect of bacteria on clinical symptoms was examined. A positive correlation between bacterial growth and clinical symptoms was found. Peptococcus magnus and Bacteroides species were commonly found in clinically acute cases, while oral streptococci and enteric bacteria were frequently isolated from clinically asymptomatic cases. and Goodman (8) ...

This paper describes a new nonsurgical approach for treating large periapical lesions which involves using a modified vacuum system within the root canal space. This new technique produces a vacuum effect in the periapical zone, which facilitates evacuation of large amounts of inflammatory fluids. This technique was used in 3 clinical cases, in which the patients presented with copious amounts ...

Conventional nonsurgical endodontic treatment has a high degree of clinical success, but in certain cases surgical intervention becomes necessary. This is the case report of a patient presenting with bilaterally separate periapical lesions in the maxillary anterior region. One lesion was managed by periapical surgery using a novel and safe method of separating the soft tissue mass of the periap...

Apical periodontitis is an inflammatory disorder of periradicular tissues caused by aetiological agents of endodontic origin. The subject has been reviewed by Nair. (1)(2) They are believed to result from inflammatory processes in the periapical tissues associated with bacterial infection and necrosis of the dental pulp in carious teeth. As a consequence of these processes and the inability of ...

The new Apexum procedure (Apexum Ltd, Or-Yehuda, Israel) is based on a minimally invasive removal of periapical chronically inflamed tissues through a root canal access. Apexum procedure (a novel method that allows for the removal or debulking of periapical tissues without using scalpels, periosteal elevators, or sutures) results in significant less postoperative discomfort or pain than convent...

The success of root canal treatment is based on total elimination of root canal content, thorough cleaning, shaping and obturation of root canal system. Calcium hydroxide is recommended as intra-canal medicament because of its antibacterial properties, tissue dissolving ability, inhibition of tooth resorption and indication of tissue repair by hard tissue formation. Here we present a series of ...

This case report presents conservative management of unset mineral trioxide aggregate (MTA) after being placed as a root-end filling material following periapical surgery. Periapical surgery was indicated for a maxillary lateral incisor of a 15-year-old male due to persistent exudate and a large periapical lesion. During surgery Angelus MTA was placed as root-end filling. The next session it wa...

INTRODUCTION Digital radiographic imaging systems have undergone tremendous improvements since their introduction. Advantages of digital radiographs over conventional films include lower radiation doses compared with conventional films, instantaneous images, archiving and sharing images easily, and manipulation of several radiographic properties that might help in diagnosis. METHODS A total o...
