The presence or absence of periapical radiolucencies, after a predetermined healing period, have been used as a criteria for therapeutic success or failure in endodontic treatment. However, in radiologic diagnosis it has been shown that variations within and between examiners are substantial. In the present study six endodontists evaluated the periapical tissues in radiographs of 119 endodontic...

Paresthesia is a burning or prickling sensation or partial numbness resulting from neural injury. Paresthesia resulting from periapical pathosis or various stages of root canal treatment is of great importance in the field of endodontics. The purpose of this paper is to review paresthesia caused by periapical lesions, local anesthesia, cleaning, shaping and obturation.

The radicular cyst has been classified as inflammatory cyst, as a consequence to pulpal necrosis following caries, with an associated periapical inflammatory response. Many times it is d ifficult to differentiate radicular cysts from the obligatory pre-existing chronic periapical periodontitis lesions radiographically. This paper presents a case of radicular cyst in the maxillary anterior region.

INTRODUCTION Periapical surgery is the last resort in the arsenal of an endodontist to effectively deal with periapical lesions that result from necrosis of the pulp. Bone grafts, growth factors and membranes form an array of regenerative materials that influence the healing outcome of periapical surgery. PRESENTATION OF CASE The main purpose of the two cases reported here was to assess the p...

PURPOSE The aim of this study was to systematically review the evidence for periapical implant lesion, which makes a patient more susceptible to the periapical lesion, frequency, symptoms, signs (including radiological findings) and possible treatment options. MATERIAL AND METHODS A systematic literature review and analysis of publications included in PubMed, Embase and Cochrane; articles pub...

BACKGROUND To evaluate the prevalence and the characteristics of jaw lesions diagnosed in young adults aged 20 to 30 years in a southern Brazil reference center, over a period of 25 years. And to analyze the concordance between clinical and histological diagnosis. MATERIAL AND METHODS In this cross-sectional retrospective study, the biopsies files from this center were retrieved and data rega...

To be able to determine if endodontic treatment of apical pathosis is successful or not, healing of lesions is followed up by radiographic imaging. This can be done by observing changes in apical radiolucencies. Recently, cone beam computed tomography (CBCT) has been introduced as a method of gaining an unabridged view of dental anatomy, thus eliminating some of the most prevalent problems, suc...

This study evaluated the effectiveness of ultrasound, color Doppler imaging and conventional radiography in monitoring the post-surgical healing of periapical lesions of endodontic origin. Fifteen patients who underwent periapical surgery for endodontic pathology were randomly selected. In all patients, periapical lesions were evaluated preoperatively using ultrasound, color Doppler imaging and...

Periapical lesions are caused by bacterial infections. The fundamental objective of endodontic treatment is to eliminate bacteria present in the root canal system because they play an important role in the development and maintenance of periapical lesions. Therefore, confirming the absence of bacteria before filling root canals is important. Anaerobic culture tests have been used in many endodo...
