Pulpal and periradicular pathosis are the result of microbial, mechanical, or chemical invasion. Microorganisms are the main irritants of pulpal and periapical tissues. The goal of the obturation is to obtain a fluid-tight seal of the root canal system from its coronal aspect through its apical extent to preserve from the irritants.. Root apices have morphological irregularities in teeth with p...

AIM To determine the pH of pus collected from periapical abscesses. METHODOLOGY Forty patients (Male = 17/Female = 23) between the ages 17 and 37 years, each with a periapical abscess and with no relevant medical history, were recruited. All the participants had moderate-to-severe pain on percussion accompanied by localized or generalized swelling. At least 1 mL of pus was aspirated from each...

Periapical surgery is a well-accepted technique used to salvage endodontically involved teeth that cannot be satisfactorily treated or retreated by nonsurgical conventional endodontic procedures (1-4). Indications for periapical surgery are well described in the above mentioned endodontic references. Considering that the prognosis of success following endodontic surgery ranges from 60 to 89% (5...

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 ...
