The influence of image display systems on observers' preference for visualizing subtle dental radiographic abnormalities.

Objective: The objectives of this study were to assess observers' preference for standard screens (SSs) or medical displays (MDs) in visualizing difficult-to-diagnose radiographic dental abnormalities and their preference for dental filter tools when utilized with MD systems.

Study Design: A retrospective data set of 60 in vivo radiographs consisting of intraoral (n = 20), panoramic (n = 20), and cone beam computed tomography (n = 20) images was created. Three image display monitors, including an SS, an MD, and an MD with 3 dental filter configurations (bone-low density enhancement filter, tooth-high density enhancement filter, and a combined filter representing regular MD), were utilized to assess 4 observers' monitor preferences in detecting radiographically subtle dental abnormalities.

Observer preference for a dedicated medical display vs a standard screen in the detection of dental radioanatomic features.

Objective: The aim of this study was to assess observers' preference for a dentomaxillofacial dedicated medical display (MD) vs a general-purpose standard screen (SS) for in vitro and in vivo observation of normal radioanatomic features.

Study Design: The in vitro sample consisted of 2-dimensional (2-D) intraoral (n = 15), panoramic (n = 2), cephalometric (n = 2), and 3-dimensional (3-D) cone beam computed tomography (CBCT) (n = 9) data sets, acquired by utilizing commercially available skull and head-and-neck phantoms. The in vivo sample consisted of 80 radiographs (intraoral = 20; panoramic = 20; cephalometric = 20; and CBCT = 20).

Halve the dose while maintaining image quality in paediatric Cone Beam CT.

Cone beam CT (CBCT) for dentomaxillofacial paediatric assessment has been widely used despite the uncertainties of the risks of the low-dose radiation exposures. The aim of this work was to investigate the clinical performance of different CBCT acquisition protocols towards the optimization of paediatric exposures. Custom-made anthropomorphic phantoms were scanned using a CBCT unit in six protocols.

Image quality assessment of pre-processed and post-processed digital panoramic radiographs in paediatric patients with mixed dentition.

Purpose: To determine the impact of an image processing technique on diagnostic accuracy of digital panoramic radiographs for the assessment of anatomical structures in paediatric patients with mixed dentition.

Materials And Methods: The study consisted of 50 digital panoramic radiographs of children aged from 6 to 12 years, which were later on processed using a dedicated image processing method. A modified clinical image quality evaluation chart was used to evaluate the diagnostic accuracy of anatomical structures in maxillary and mandibular anterior and maxillary premolar region of processed images.

Update on a rare mandibular osteolytic lesion in childhood: the buccal bifurcation cyst.

Buccal bifurcation cyst is a rare, uncommon buccal cystic lesion associated with the permanent mandibular first molar in children just prior to tooth eruption, and is categorized by the World Health Organization as an odontogenic cyst occurring in a vital tooth, near the buccal cervical margin of the lateral aspect of a root, as a result of an inflammatory process in a periodontal pocket. The aim of this study is to present a series of three similar mandibular buccal bifurcation cyst cases, by providing clinical, radiological and histological characterization of the lesion, in order to lead clinicians through the diagnosis, treatment and follow-up process and contribute to deeper knowledge of this rare pathological entity.

CBCT in orthodontics: a systematic review on justification of CBCT in a paediatric population prior to orthodontic treatment.

Background: Taking into account radiation doses, safety, and protection, we highlighted the features in which cone-beam computed tomography (CBCT) can offer an advantage compared to the conventional two-dimensional imaging in paediatric dentistry before orthodontic treatment.

Objective: The aim of this article was to conduct a systematic review to assess the diagnostic efficacy of CBCT in the paediatric population at a pre-orthodontic phase.

Search Methods: MEDLINE via PubMed was searched to identify all peer-reviewed articles potentially relevant to the review until 1 July 2018.
