OBJECTIVES To survey the current radiographic prescriptions in dental implant assessment amongst dentists in Brazil. METHODS Sixty-nine dentists were interviewed during a dental implant meeting by two calibrated graduate students, using a 19-question questionnaire, considering imaging modality options both for pre-operative implant site assessment and for follow-up, particularly with respect ...

PURPOSE The aim of the present study was to evaluate the measurement accuracy of endodontic file length on periapical digital radiography after application of noise reduction digital enhancement. MATERIALS AND METHODS Thirty-five human single-rooted permanent teeth with canals measuring 20-24 mm in length were selected. ISO #08 endodontic files were placed in the root canals of the teeth. The...

AIM To report a clinical case of unicystic ameloblastoma previously misdiagnosed as radicular cyst. SUMMARY A 49-year-old white male was referred to a private practitioner complaining of an asymptomatic bony hard swelling of the left posterior mandible. The patient's dental history indicated that his left mandibular first molar had been extracted approximately 10 years previously. At that tim...

Dental root resorption especially in maxillary incisive region almost always happens simultaneously with orthodontic treatment, and it gained researchers attention, in particular after the use of periapical radiography. However, the fundamental etiology of dental root resorption is still dubious. Multifactoral causes are mentioned, among others are hormonal, nutritition, trauma, dental root for...

Before the advent of OPG and CBCT; Intraoral periapical radiography was mainstay of dental imaging since years. CBCT was rst adapted for potential clinical use in 1982 at the Mayo Clinic Biodynamics Research Laboratory. This technique is a recent development and is found to be more efcient and economical than conventional tomography or CT in oral diagnosis. CBCT allows better 3D visualisation...

Abstract The aim of this article is to discuss the sequelae a missing tooth from normal series dental arch and importance cone beam computed tomography (CBCT) in diagnosis treatment planning such cases. We also correlate position an impacted maxillary premolar as seen on panoramic radiography with CBCT. Routine imaging modalities like intraoral periapical, occlusal, view often give inadequate i...

Paresthesia is a neurosensitivity disorder caused by injury to the neural tissue. It is characterized by a burning or twinging sensation or by partial loss of local sensitivity. Paresthesia related to endodontic treatment can occur because of extravasation of filling material or the intracanal dressing, as a consequence of periapical surgery or because of periapical infection. A literature revi...

The aim of this study was to evaluate the accuracy of linear measurements made on conventional and digitized periapical and panoramic radiographic images of dry human hemi-mandibles. Images from the posterior region of 22 dry human hemi-mandibles were obtained by conventional panoramic and periapical radiography technique. Using a digital caliper, 3 vertical measurements were marked directly on...

introduction: the purpose of this clinical study was to compare the accuracy of working length (wl) determination using cone-beam computed tomography (cbct), conventional periapical radiographies and electronic apex locator. methods and materials: this study was conducted during root canal treatment of 19 patients with a total of 30 single-rooted teeth diagnosed with apical periodontitis. after...
