"Healthy " ambulant subjects whose ages ranged from 5 to 66 years were selected from hospital staff and outpatients, according to the following criteria: (1) absence of urinary symptoms, (2) absence of past history of urinary symptoms or previous bilharzial infection, (3) absence of bilharzial ova in a midday specimen of urine, (4) viable urinary bacteria count of less than 10,000/ml., and (5) ...

Radiographic demonstration of calcification within spinal canal tumors is rare [1] . The most common lesion of this type showing calcification is a meningioma. Other lesions showing calcification include neurofibromas, hemangioblastomas, neuroblastomas, ganglioneuromas, and herniated thoracic disks. Very rarely is calcification seen within neurilemomas [2, 3] , and, if present, it may be noted ...

Locating the number and position of orifices on pulp-chamber floors can be difficult. This is especially true when the tooth being treated is heavily restored, malposed, or calcified. After evaluating 500 pulp chambers of extracted teeth, new laws for finding pulp chambers and root-canal orifices are proposed. The use of these laws can aid in the determination of the pulp-chamber position and t...

INTRODUCTION The aim of this in vitro study was to compare the canal transportation of two single-file engine-driven systems, Neoniti and Reciproc, using cone-beam computed tomography (CBCT). METHODS AND MATERIALS Forty-five non-calcified roots with mature apices and apical curvature of 15-30 degrees were selected from extracted human maxillary molars for this study. Samples were randomly div...

AIM To describe the application of GT files in roots with abrupt curvatures. SUMMARY Most dentists interpret obstructions to instrument progress as calcification, rather than abrupt curvature. Basically, there are not any apically calcified canals, only clinicians who are not clever enough or patient enough to sneak to patency. Dentists should be on their guard and sensitive to the 'rubber ba...

In this review, we examined a 45-year-old Asian man who had been diagnosed with florid osseous dysplasia (FOD) of the mandible and acute perimandibular cellulitis. This presentation occurred after a history of off-and-on swellings of the jaw and multiple treatments received at another hospital. An aggressive resection of the jaw was planned; however, the patient denied the treatment and came to...

CASE REPORT Root canal treatment was performed in a mandibular right second premolar with a periapical lesion and apical resorption. The root canal was prepared with K-files using the step-back technique and 3% NaOCl as an irrigant; during obturation gross overfilling of gutta-percha occurred. The tooth was permanently restored with a post and core along with a crown. Although healing of the pe...

It has been observed that the root canal treatment for the preservation of tooth having periapical pathology has shown over 90% of success whereas in the case where the canal is calcified, perforated, ledge is formed, and cases where symptoms still exist after treatment, endodontic treatment may not be the solution in attaining a successful treatment. Thus Apisectomy would generally be done to ...
