“…CBCT was used in this study as an appropriate option for high-quality image resolution and is feasible for use in adolescents with CP, considering the ease in positioning of the patient, low cost, rapid acquisition, and lower amount of radiation emitted. Studies have shown that exposure to radiation with CBCT corresponds to 20% of exposure generated in fan-beam computed tomography (FBCT) and is equivalent to a complete periapical radiographic series (14 periapical radiographs) [21]. The results of this study were obtained using CBCT images, as this technique allows for bone and density measurements at the edge of the mandible and is feasible for use in adolescents with CP.…”

Objective:The aim of this study was to assess the bone density of the mandible in adolescents with cerebral palsy (CP) treated with antiepileptic drugs using one beam computed tomography (CBCT). Methods: The study was carried out with 18 adolescents aged 12-18 years, undergoing routine dental treatment at the dental clinic of APCD-São Caetano do Sul. CBCT scans were of divided into two groups: G1 adolescents with CP using antiepileptic drugs and G2 normoactive adolescents. A single dentomaxillofacial radiologist assessed and evaluated the images using Dental Slice software and Image J. Fisher's exact tests as well as paired and unpaired Student's t-tests were performed. Results: Groups differed significantly with regard in the values of density (p < 0.001), with G1 presenting lower values compare to G2. G1 showed significantly lower density means on the right side, left side, and right/left sides of the mandible edge than G2 (p < 0.001). Conclusion: CP patients using antiepileptic drugs show evidence of bone mineral density loss of the mandible.

Background: Three-dimensional (3D) imaging has been widely utilized in dentistry to improve diagnosis, treatment planning and appliance fabrication.Technology was come increasingly important with developments in 3D imaging and modeling technology such as (CBCT), intraoral scanning and CAD/CAM. 3D imaging provides more precise and realistic diagnosticinformation on craniofacial hard and soft tissue, making 3D analysis easier, faster and more reliable, to assess the knowledge, attitude and practice regarding 3D imaging in Saudi Arabian dental practitioners. Methodology: In our study, a Google forms online survey consisting of 25 questions was sent to orthodontists, orthodontic residents and general dentists and dental interns in Saudi Arabia. Additionally, the questionnaire was asked about dental practitioner perceptions of three-dimensional (3D) imaging. The data obtained was analyzed using the following tests: Descriptive statistics tests (frequency, mean, median and mode, range and standard deviation), chi square test. Results: The study included 1574 participants, 58.1% of them were males and 41.9% were females. 40.2% were intern, 38.4% had less than five years of experience, 12.4% had 5-ten years of experience and 9% had more than ten years of experience. 91.4% of participants think that 3D imaging has advantages over other digital imaging modalities. Conclusion: The study shows that Saudi dentists have moderate knowledge of 3D imagining in dentistry. Knowledge levels have a strong correlation with ages, practice, residence region, gender and work experience.

“…Three-dimensional (3D) imaging systems can be used to objectively assess facial morphology in a variety of research and clinical settings. Some examples include the evaluation of congenital craniofacial dysmorphisms 1 and for the early screening of genetic anomalies, 2 along with pretreatment planning and treatment monitoring in orthodontics 3 and facial aesthetic surgery. 4,5 Compared to two-dimensional (2D) imaging, 3D methods have been shown to be more accurate and reliable, especially when assessing complex facial movements such as smiling and oral synkinesis.…”

Background: Three-dimensional imaging can be used to obtain objective assessments of facial morphology that is useful in a variety of clinical settings. The VECTRA H1 is unique in that it is relatively inexpensive, handheld, and does not require standardized environmental conditions for image capture. Although it provides accurate measurements when imaging relaxed facial expressions, the clinical evaluation of many disorders involves the assessment of facial morphology when performing facial movements. The aim of this study was to assess the accuracy and reliability of the VECTRA H1, specifically when imaging facial movement. Methods: The accuracy, intrarater, and interrater reliability of the VECTRA H1 were assessed when imaging four facial expressions: eyebrow lift, smile, snarl, and lip pucker. Fourteen healthy adult subjects had the distances between 13 fiducial facial landmarks measured at rest and the terminal point of each of the four movements by digital caliper and by the VECTRA H1. Intraclass correlation and Bland–Altman limits of agreement were used to determine agreement between measures. The agreement between measurements obtained by five different reviewers was evaluated by intraclass correlation to determine interrater reliability. Results: Median correlation between digital caliper and VECTRA H1 measurements ranged from 0.907 (snarl) to 0.921 (smile). Median correlation was very good for both intrarater (0.960–0.975) and interrater reliability (0.997–0.999). The mean absolute error between modalities, and both within and between raters was less than 2 mm for all movements tested. Conclusion: The VECTRA H1 met acceptable standards for the assessment of facial morphology when imaging facial movements.
