This study investigated the accuracy of diagnosing periapical lesions through conventional radiography (CR) and direct digital radiography (DDR) technique. A total of 170 patients with clinically suspected periapical pathosis and 30 normal subjects were included in the study. Both the conventional and digital images were taken with same exposure parameters keeping the film without lead foil and...

INTRODUCTION Endodontic retreatment is a complex intervention that requires detailed analysis of possible reasons for failure, and flawless practical execution of the procedure. OBJECTIVE The aim of the study was to assess the outcome of endodontic retreatment based on clinical and radiographic criteria after a two-year observation period. METHODS Clinical study included 49 teeth indicated ...

INTRODUCTION Studies have shown the regulatory role of Leptin in bone formation, its expression in adipose tissue as well as increased levels in circulation following the adminstration of inflammatory stimuli such as lipopolysaccharides (LPS). However, there is little data evaluating the role of Leptin in inflammatory periapical lesions. The aim of this study was to evaluate the presence and co...

Objectives: To assess and compare five diagnostic imaging methods used in the identification of periapical diseases, of different diameters, mechanically simulated. Methods: The sample of the present study consisted of 12 dried human mandibles. Digital panoramic radiography, conventional and digital periapical radiography (charged couple device and photo-stimulable phosphor plate), and high-res...

BACKGROUND AND AIMS Chronic periapical disease with pulpal origin is an inflammatory condition caused by bacterial infection. Chronic infection could affect general health by increasing the production of cytokines such as interleukin-6 (IL-6) that probably play a role in pathogenesis of pulpal and periapical diseases. The aim of the present study was a comparative evaluation of the level of ser...

This manuscript summarizes the statements and clinical recommendations in periapical implant lesions, as per the state of the art and expert opinion agreement among the participants in the 9th Mozo-Grau Conference 2016 held in Quintanilla (Valladolid, Spain). The current status of the concept, frequency, etiology, diagnosis, clinical classification, surgical procedure and prognosis are describe...

Specific immunity has been implicated in the pathogenesis of periapical lesions, although the extent to which these mechanisms are actually involved in either protection or destruction of the pulp-periapex complex is yet to be established. To investigate this question we compared periapical-lesion pathogenesis in RAG-2 severe combined immunodeficient (SCID) mice with immunocompetent control mic...

HEIDI KOHLTFARBER, DDS: A Comparison of 2D versus 3D Radiography in the Diagnosis and Treatment Planning of Root Canal Treated Teeth with Periapical Lesions (Under the direction of Donald Tyndall) Objectives: The aims of the study were to assess diagnostic efficacy in lesion detection, evaluate the effect of cone beam CT on treatment planning and clinician confidence. Methods: Forty digital per...

Large periapical lesions, regardless of whether they are granulomas, abscesses or cysts, are primarily caused by root canal infection. Thus the treatment protocol should be elimination of etiological factors in the root canal system rather than their product, apical true cyst. A 10 year old female patient reported to the Department of Pedodontics and Preventive Dentistry, Dr R Ahmed Dental Coll...

The presence of Enterococcus faecalis in root canal teeth affected by primary and secondary periapical lesions was studied using polymerase chain reaction (PCR) assays. The association between presence of E. faecalis with clinical signs of apical lesions was assessed to evaluate a possible relationship between clinical findings. Microbial samples were obtained from healthy patients affected by ...
