The recently updated National Council on Radiation Protection and Measurement Radiation Protection in Dentistry and Oral and Maxillofacial Imaging (NCRP Report No. 177) prompts this review of progress related to patient thyroid shielding since the ATA statement was published. Summary Relevant publications appearing since the ATA statement were identified by querying PubMed for "thyroid and dental and (collar or shielding)" and substituting specific dental radiographic procedures in the search. The search was expanded by reviewing the cited papers in the PubMed-retrieved papers and by use of the Web of Science to retrieve papers citing the PubMed retrieved publications. Although many quantitative studies have appeared reflective of current dental radiographic instrumentation and practice, much more can be done to foster minimizing radiation to the thyroid. Conclusions We list seven areas that should be pursued. Among them are harmonizing guidelines for the use of thyroid collars based on the recent studies and a comprehensive survey of current dental radiological practice patterns.This study investigates college students' exposure to messages about campus dating and sexual violence (DSV) to discover classes of students based on the message source. Latent class analysis was performed with data assessing 5,284 students' exposure to 16 different sources of information regarding DSV, from having a professor discuss these topics to participating in related campus events. Several variables were included in the analysis to understand students' class membership in relation to pertinent student demographic factors. The best model indicated that there are five classes of students based on their exposure to messages, with some subgroups of students having high exp
