Imaging of odontogenic keratocyst of the jaw by panoramic radiography: a scoping review

Objectives: This review article is aimed to determine the imaging of odontogenic keratocyst of the jaw by panoramic radiography. Review: This research is a descriptive research using the scoping review method based on the Preferred Reporting Items for Systematic Review and Meta-analysis Scoping Review (PRISMA-Scr) which was conducted from February 2021 to April 2021. The search for literature related to the research topic was carried out through database of scientific articles on PMC NCBI, Pubmed NCBI, and Garuda as well as hand searching. The identified articles were screened by checking for duplicates, reading the titles and abstracts, and reading the entire articles. A total of 16 articles were included out of 161 articles in total. Conclusion: Imaging of odontogenic keratocyst of the jaw by panoramic radiography is most commonly found in the 1st and 2nd decades of life and in males, the lesions are unilocular or multilocular radiolucent and have an envelopmental shape in which the outline of the cyst surrounds the entire unerupted tooth. OKCs have well-defined with sclerotic or scalloped margins, most often occur in the posterior mandible and often associated with impacted 3rd molars, root resorption was a rare occurrence

Knowledge, attitude and perception on radiation imaging among children's caregivers in the pediatric dental clinic

OBJECTIVE: Nuclear medicine provides important clinical information for diagnostic and therapeutic purposes. Use of medical imaging has gradually increased in the United States and this has raised health concerns about the potential future risks associated with radiation exposure in children. While studies have evaluated the adverse effects of imaging procedures, there is insufficient evidence about communicating radiation risks. The overall purpose of this paper is to review radiation risks in pediatric imaging using published evidence by the World Health Organization and to evaluate the knowledge and attitude of caregivers towards radiation risks in pediatric imaging. Specifically, we aim to determine whether an educational brochure improves parental knowledge of radiation and/or changes in attitude and perception to allow their children to undergo dental radiographs. METHODS: A prospective sample survey was performed of caregivers who presented with their child to the Boston University Pediatric Oral Healthcare Center. Parents or legal guardians (18 years or older) who accompanied a child were eligible for inclusion and approached for enrollment. Pre- and post-survey questionnaires were used to evaluate parents’ or guardians’ level of knowledge and attitude about the risks and benefits of dental radiographs. Parents were also asked their comfort level to allow their child to undergo dental radiographs. After completing the pre-survey questionnaire, parents were asked to read the English-language informational handout. Statistical analysis was performed through Microsoft Excel 2013. Descriptive analysis was conducted to summarize the survey responses. RESULTS: Among 30 parents who were surveyed, a small proportion (30%) of parents were very comfortable with dentist using dental radiographs on their child, versus 57% after reading the handout. Results showed that the informational handout improved the parental knowledge of risks and benefits of ionizing radiation. Most parents indicated that the handout was helpful and they reported increased level of comfort and willingness in their children receiving radiation imaging during dental treatment procedures. DISCUSSION: Educating parents or caregivers through an informational handout is a helpful resource in improving their knowledge and in relieving their concerns. Informing parents about the risks of ionizing radiation does not change parental willingness for their children to undergo dental radiographs

Lead X-Ray Vests: Pros and Cons in Dental Radiography and Patient Education on Radiographic Technology

Problem: There is a greater need to emphasize and educate patients and providers about radiologic advancements and patient exposure. The tradition of placing lead x-ray vests on patients for all radiographs is no longer a necessity. Without the explanation of why lead aprons are no longer needed, unnecessary steps for the provider and potential harm to the patient could be caused. Methods: This review of literature was assembled by analyzing data from primary and secondary sources through online databases. The most recent research on the risks and benefits of the use of lead x-ray vests towards patients in the dental office was examined. Articles included in this review were published within the last five years. Major Findings: Studies show the use of lead x-ray vests is widely obsolete with most new types of radiographic technology. Conclusions: Collimation and new digital radiographic devices have dramatically decreased patient radiation exposure by limiting the beam to a confined space on the patient\u27s oral cavity. There is also a risk that vests may pose a lead exposure hazard if not taken care of properly. The general patient population is widely unaware of these advancements in x-ray technology and of the ineffectiveness of lead aprons.https://scholarscompass.vcu.edu/denh_student/1020/thumbnail.jp

Assessment of plastics in the National Trust: a case study at Mr Straw's House

The National Trust is a charity that cares for over 300 publically accessible historic buildings and their contents across England, Wales and Northern Ireland. There have been few previous studies on preservation of plastics within National Trust collections, which form a significant part of the more modern collections of objects. This paper describes the design of an assessment system which was successfully trialled at Mr Straws House, a National Trust property in Worksop, UK. This system can now be used for future plastic surveys at other National Trust properties. In addition, the survey gave valuable information about the state of the collection, demonstrating that the plastics that are deteriorating are those that are known to be vulnerable, namely cellulose nitrate/acetate, PVC and rubber. Verifying this knowledge of the most vulnerable plastics enables us to recommend to properties across National Trust that these types should be seen as a priority for correct storage and in-depth recording

Some Pattern Recognition Challenges in Data-Intensive Astronomy

We review some of the recent developments and challenges posed by the data analysis in modern digital sky surveys, which are representative of the information-rich astronomy in the context of Virtual Observatory. Illustrative examples include the problems of an automated star-galaxy classification in complex and heterogeneous panoramic imaging data sets, and an automated, iterative, dynamical classification of transient events detected in synoptic sky surveys. These problems offer good opportunities for productive collaborations between astronomers and applied computer scientists and statisticians, and are representative of the kind of challenges now present in all data-intensive fields. We discuss briefly some emergent types of scalable scientific data analysis systems with a broad applicability.Comment: 8 pages, compressed pdf file, figures downgraded in quality in order to match the arXiv size limi
