Objectives. To establish the radiographic prescriptions in dental implant assessment amongst dentists in Romania. Materials and method. Fifty-four dentists were interviewed during a dental meeting, using a 15-questions question)naire, regarding the imaging modality options for both preoperative implant site assessment and for follow-up. We took into consideration particularly the cost, the patient’s radiation dose for each imaging prescriptions, and the broad coverage of facial bones and teeth. Results. The majority of dentists (34) prescribed only panoramic radiographs for dental implant assessment, and 10 dentists (18.5%) ordered panoramic radiographs plus periapical radiographs and/or conventional tomography and/or cone beam computed tomography (CBCT). Only three (5.55%) of the interviewed dentists prescribed conventional tomography or CBCT as a single examination, and seven of those interviewed preferred the combination of cone beam computed tomography or of conventional tomography with other imaging methods. In the frequency order, the main reason given for prescribing panoramic radiographs were broad coverage, cost, acces)sibility, and radiation dose. Conclusions. This study revealed that most of the Romanian dentists prescribe for dental implant assessment only panoramic radiographs. Thus, they are not following or ignore the recommendations of the international societies of dentomaxillofacial imaging regarding the use, in oral implantology, of the cross-sectional imaging techniques.

The accurate visualization of the endodontic system before root canal treatment is the premise for the predictable positive outcome of the clinical procedures. The conventional X-ray gives a two dimensional view of a tridimensional reality. There are anatomy details impossible to detect with 2D imaging. The Cone beam computed tomography (CBCT) gives us the possibility to view and understand the special morphology of the anatomic structures of the teeth, bone and surrounding tissues. CBCT should be standard of care when 3D imaging is necessary in endodontics. CBCT helps us visualize the root canal anatomy: number of roots and root canals, shape, cross sections, curvatures, volume of the root canals; also obscure or missed canals, proximity to the mandibular canal (IAN) or the sinus. Examining the root canal system in three dimensions is actually a great asset for the endodontic treatment. [ABSTRACT FROM AUTHOR]

Bone defects of various causes – infectious, trauma, congenital – are important medical and socio-economical problems because of impossibility of spontaneous healing, difficult treatment and long healing period. Autografts, allografts and bone substitutes play an important role in bone reconstructive surgery. The aim of this research was evaluate the accuracy and the reliability of assessing small bone defects regeneration using two imaging methods: RVGVisiodent and NewTom CBCT. [ABSTRACT FROM AUTHOR]

The aim of our study is the radiological and CBCT testing of the complete healing of chronical apical lesions. Materials and method. The study has taken place in the Endodontic Clinic of the Faculty of Dental Medicine in Craiova on twelve patients with different forms of chronical apical periodontitis. Conservatory root canal treatment has been performed to all patients. Radiological and CBCT exams have been effectuated immediately after the root canal filling and being repeatedly recalled for the same investigation 6 months, 1 year and finally 2 years after. Results and discussions. During recalls, we noticed the disappearing of apical radiolucency from the first year after finishing treatment at 6 patients and after 2 years this phenomenon occurred at another 4 patients, as for 2 patients the conservatory treatment of apical lesions failed. On CBCT exam, we observed total disappearing of apical radiolucency at only 2 patients in the first year after the treatment and at 6 patients 2 years after. Therefore, the results show an improvement of accuracy when evaluating the healing degree of chronical apical lesions. Conclusions. CBCT images prove a much higher accuracy in detecting lesions that persist after conservatory treatment of apical lesions than classical radiological exams that may lead to false positive results.
