W ith the increasing acceptance of dental implants, there is a greater need for the dental profession to ensure the recipient site for an implant is adequate. The presence or absence of an anatomical limitation should always be confirmed beyond a reasonable doubt. Conventional two-dimensional radiographs (PAs, or panoramic films) 1 have limitations as diagnostic tools because they don't convey ...

The aim of this report was to characterize osteonecrosis of the jaws (ONJ) in previously irradiated fields in dogs that underwent radiotherapy (RT) for oral tumors. Osteoradionecrosis of the jaw (ORNJ) was further defined as osteonecrosis in a previously irradiated field in the absence of a tumor. Thirteen dogs clinically diagnosed with 15 ONJ lesions were included in this retrospective case se...

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 ...

OBJECTIVES To develop "basic principles" on the use of dental cone beam CT by consensus of the membership of the European Academy of Dental and Maxillofacial Radiology. METHODS A guideline development panel was formed to develop a set of draft statements using existing European directives and guidelines on radiation protection. These statements were revised after an open debate of attendees a...

Two mainland Japanese males were examined with a computer tomography (CT) X-ray scanner to reconstruct three-dimensional CT simulation images of their cranial anatomy and to check for the presence/absence of 23 nonmetric cranial traits. Surface anatomy for scoring 19 nonmetric cranial variations was clearly observed among the 23 variations. Evaluation of the four other traits might have been di...

Medical radiation exposure of the U.S. population has not been systematically evaluated for almost 25 y. In 1982, the per capita dose was estimated to be 0.54 mSv and the collective dose 124,000 person-Sv. The preliminary estimates of the NCRP Scientific Committee 6-2 medical subgroup are that, in 2006, the per capita dose from medical exposure (not including dental or radiotherapy) had increas...

The purpose of this paper is to present a comparison of doses delivered to the patients when dealing with intra-oral, panoramic and CT dental examinations. The technology progress will be discussed from a dose and an image quality point of view. DAP values were measured for two intra-oral systems using speed D and E/F dental films, and a digital system in two different acquisition modes (CCD te...

The rapid development of dental implantology in recent years made the use of CT preoperative study a common part ofdetailed operational planning. Establishing the quality of residual alveolar bone in the area of interest, for the needs of successful osseointegration of endosteal implants, is an important part of the preoperative study . In the presence of an active bone transformation in the zo...

Streaking artifacts on computed tomography (CT) images are caused by high density materials such as hip prosthesis, surgical clips and dental fillings. The artifacts can lead to compromised clinical outcome due to the inability to differentiate tumor volume and the uncertainties in dose calculation. The goals of our study are to evaluate how GE’s smart metal artifact reduction (MAR) algorithm i...
