INMICROSCOPY, AS INNATURE,ONERECOGNIZESONLYWHATONEALREADYKNOWS. Routine histopathological diagnostic reports and publications based on retrospective reviewing of such, perpetuate the notion that nearly half of all apical periodontitis lesions are cysts. Studies based onmeticulous serial sectioning of apical lesions retrieved in toto show that the actual prevalence of cysts is only about 15% of ...

BACKGROUND This study aimed to evaluate the accuracy of two imaging methods in detecting the apical pathology in endodontically treated teeth. MATERIAL AND METHODS A clinical examination from a sample of 156 teeth of patients treated by students of masters in endodontics at the Care Center of the Faculty of Dentistry at St. Joseph University, Beirut was done after 5 years of follow-up. Perira...

The only sign of chronic apical periodontitis is periapical lesions that are seen in radiographs. Lesions are visible when the inflammation reaches cortical plates. Lesions located in cancellous bone, cannot be easily seen in radiography. Developing computerized technology in radiography, which has numerous advantages and its show up devices in the market, encourage the clinicians to take advan...

Periapical lesions are the most common pathological conditions involving teeth which often require surgical intervention. To achieve optimal healing both clinically and radiographically, bone grafts and barrier membranes have been used to fill the periapical defect after degranulation of the lesion. Colostrum is one of the new materials, which has osteoinductive or regenerative potential. The p...

Great attention has been given to the study of radiolucent periapical lesions to avert possible misdiagnosis of apical periodontitis associated with certain radiolucent non-endodontic lesions. However, there are a significant number of radiopaque lesions found in the periapical region, which could be equally relevant to endodontic practice. The diagnosis and management of these radiopaque/hyper...

BACKGROUND To determine the prevalence of periapical lesions in root canal-treated teeth in a rural, male adult, Turkish population and to investigate the influence of the quality of root canal fillings on prevalence of periapical lesions. METHODS The sample for this cross-sectional study consisted of 552 adult male patients, 18-32 years of age, presenting consecutively as new patients seekin...

Periapical radiography is essential in diagnosis, treatment planning and follow-up in endodontics. However, image interpretation can be confounded by geometric distortion, superimposition of regional anatomy and technique errors. These problems can be overcome by utilizing small or limited-volume cone beamcomputed tomography imaging techniques, which produce accurate 3-D images of the teeth and...
