Background and Aims: There has been a rising concern regarding the relationship of iron levels, vitamin D, and consumption of multivitamins on pain perception and sleep quality. The purpose of this study is to shed light on these connections in hopes of enhancing quality of sleep. Methods: A cross-sectional analysis was used, and data collection was based on close-ended online questionnaire created on Survey Monkey. The survey included an operator designed questionnaire, questions from both the Brief Pain Inventory and Sleep Quality questionnaires. The targeted population was participants who were medically fit, non-pregnant Saudi citizens aged between 25 and 55 years. Results: Prior to the COVID-19 crisis, data were collected during the months of February and March 2020, with a grand total of 3127 participants, out of which 2774 responses were included. The outcome of the research revealed that diminished levels of vitamin D, and iron had a negative impact on sleep quality. In turn, poor sleep quality had a significant pain response. Conclusion: This study reveals the detrimental role of vitamins on sleep, and their concurrent domino effect on pain.

To identify sleep-domains as well as clinical features in children with trisomy 21 that may shed light on a possible sleep disturbance as compared with typically developing (TD) age-matched-controls. A convenient sample of 100 Saudi Arabian children between the ages of 3-12 were invited to participate from several schools and centers in Riyadh during February 2018 to April 2018. Fifty of these children had trisomy 21, and 50 were TD age-matched-controls. A clinical examination of participants' oral characteristics as well as the Wisconsin's 22 item Children's Sleep Habit Questionnaire (CSHQ) were utilized to help identify the impact of these variables on sleep quality. Sleep domains that harbored strong evidence in differences between the two groups were sleep anxiety, parasomnia, and sleep-disordered-breathing. The clinical features unique to trisomy 21 were Mallampati score, macroglossia, lip-incompetence, tongue-ridging, and wear-facets. Clinical features and sleep quality coexist, providing better insight into the degree of sleep disturbance a child with trisomy 21 may have. Dental clinicians must consider such factors that preclude to poor sleep, which might place children with trisomy 21 at a further disadvantage despite the fact that their baseline is already at risk of being at such a stage.

Background: To validate the Arabic translation of the Children’s Sleep Habit Questionnaire and determine the behavioral prevalence of sleep habits amongst school aged children in Riyadh, Saudi Arabia. Methods: This prospective cross sectional study involved a Linguistic validation involving 50 bilingual parent participants in each of the Arabic and English Surveys, with a cross sectional pilot involving 1546 parent participants regarding their children’s Sleeping Habits. The Children’s Sleep Habit Questionnaire was distributed via Survey Monkey and subjected to IBM-SPSS statistics. Parents of 1546 school aged children ranging from 3 years to 12 years of age completed the survey.Results: The Total score of all domains ranged between 11 and 70. Mean Score of 35-37 in 11 % of this population. The Children’s Sleep Habit Questionnaire scores were High in comparison to the Owen’s article; greater research is needed to determine the underlying causes of the increased likelihood of sleep disorders.Conclusion: Our findings, especially in sleep anxiety are alarming and warrant for more research to determine underlying causes of the more prevalent sleep disorders (Sleep Anxiety) and any other apparent or possible causes for sleep disturbances amongst children.

Aim: While obstructive sleep apnea (OSA) is among the commonest of sleep disorders, morning headache is notoriously associated with OSA. This study was conducted to assess the prevalence of reported morning headache in diagnosed cases of OSA. Materials and Methods: This was an observational cross-sectional study on 160 subjects with and without OSA, who were conveniently recruited and instructed to complete the Stop-Bang questionnaire, Diagnostic Criteria of Temporomandibular Joint Disorder screener and symptom questionnaire, as well as an Operator-designed demographic questionnaire. SPSS statistics on bivariate analysis and odds ratios were conducted. Results: Morning headache was significantly associated with those having OSA when compared with non-OSA subjects (P < 0.001). Also those who had OSA and noticed they quit breathing during sleep were nearly four times as likely to have morning headache (P < 0.027) than those with OSA who did not notice they quit breathing during sleep. Conclusion: Headache is common, but the strongest and most significant predictor of headache in OSA subjects is noticing that they quit breathing.
