Background/Aims Traumatic dental injuries, including avulsion, are relatively common, with a reported prevalence of up to 4.5%. The Internet and video‐sharing websites are frequently used as a resource for patient accessible health information. YouTube™, the online video leader, is a popular choice with patients, who decide to seek advice when managing an avulsed tooth. The aim of this study was to examine the quality of information offered by videos on YouTube™ for those individuals seeking information regarding the emergency management of an avulsed tooth. The quality of information was compared to the guidelines of the International Association of Dental Traumatology (IADT). Methods YouTube™ was searched systematically for videos on avulsion using the terms ‘knocked tooth out’ and ‘dental avulsion’. Strict inclusion and exclusion criteria were adhered to, and videos were assessed on several variables. The usefulness of the selected videos in providing adequate information about avulsed teeth was then evaluated using a 9‐point score based on the IADT guidelines. Descriptive statistics were consequently generated. Results A total of 120 videos were analysed, 13% (n = 16) of which met the inclusion‐exclusion criteria. Most had been uploaded by healthcare professionals (81%, n = 13) in the United States (63%, n = 10). Videos had generally low completeness scores (mean: 4.375 ± 1.9; range: 2‐7). Completeness was not affected significantly, either by viewers’ interactions or by the date of upload. Conclusion YouTube™ generally hosts videos with low usefulness with regard to the management of avulsed teeth. Therefore, dentists should be aware of this resource and warn parents/carers regarding the reliability of information and the misleading content which is available on YouTube™ videos.

This systematic review provides a summary of all studies published between 2000 and 2019 using a health-related quality of life (HRQOL) patient-completed questionnaire to report outcomes following diagnosis and treatment of thyroid cancer. The search terms were “thyroid cancer” or “thyroid carcinoma,” “quality of life” or “health related quality of life,” and “questionnaire” or “patient reported outcome.” EMBASE, PubMed, Medline, PsycINFO, CINAHL, and HaNDLE-On-QOL search engines were searched between 2 February and 23 February 2020. A total of 811 identified articles were reduced to 314 when duplicates were removed. After exclusion criteria (not thyroid specific, no quality of life questionnaires, and conference abstracts) were applied, 92 remained. Hand searching identified a further 2 articles. Of the 94 included, 16 had a surgical, 26 a primarily medical, and 52 a general focus. There were articles from 27 countries. A total of 49 articles were published from 2015 through 2019 inclusive. A total of 72 questionnaires were used among the articles and a range of 7 to 2215 participants were included within each article. This review demonstrated an increasing number of publications annually. The scope of enquiry into aspects of HRQOL following thyroid cancer is broad, with relatively few addressing surgical aspects and many focusing on the impact of radio-iodine. More research is required into shared decision-making in initial management decisions and HRQOL and interventions aimed specifically at addressing long-term HRQOL difficulties.

Background: Clinical observations suggest molar incisor hypomineralisation (MIH)may present with other dental conditions. Aims: The study aimed to determine the prevalence and variety of dental anomalies in children presenting with MIH. Design: A convenience sample of children referred to a UK dental hospital was recruited. Orthopantogram radiographs, taken as part of routine care, were assessed for dental anomalies. Two calibrated examiners reviewed the films separately and determined the presence and character of anomalies. Results: Radiographs were obtained from 101 patients, with an age range of 6-15 years. Co-existing hypodontia was identified in 12%, with lower second premolars being the most commonly missing teeth. Concurrent ectopic first permanent molars were identified in 8%, and infraocclusion of one or more primary molars was identified in 9%. Abnormal morphology was found in 9%, including macrodont and microdont teeth. In total, 29% of patients had an associated dental anomaly.Examiners had perfect agreement using Cohen's kappa coefficient. Conclusion: This high prevalence of dental anomalies, particularly hypodontia, in children with MIH is a novel and clinically important finding. Further research is warranted considering the potential implications for assessment and treatment planning. K E Y W O R D Sdental anomalies, hypodontia, molar incisor hypomineralisation
