Prevalence of Delayed Eruption of Permanent Upper Central Incisors at a Tertiary Hospital in Riyadh, Saudi Arabia.

Tooth eruption is defined as the axial movement of the tooth from its site of development in the alveolar bone to its functional position in the oral cavity. A delay in eruption can directly affect the accurate diagnosis, overall treatment planning, and timing of treatment. Thus, Delayed Tooth Eruption can have a significant impact on a patient's proper health care. This study aimed to estimate the prevalence of delayed eruptions of permanent upper central incisors in Riyadh, Saudi Arabia. A retrospective study assessed panoramic radiographs of children between the ages of 6-10 years old who attended the Dental University Hospital clinics at King Saud University in Riyadh, Saudi Arabia between 2014 and 2020. The radiographs were collected and examined to detect any delayed eruption of the permanent upper central incisors. Panoramic radiographs with delayed erupted permanent upper central incisors were identified by tooth developmental stages and eruption sequence. Of the 745 radiographs, 23 (3.09%) presented at least one delayed erupted permanent upper central incisor of which boys and girls comprised 16 (69.5%) and 7 (30.4%), respectively. Retained primary teeth was the most causative factor of delayed eruption (43.4%), followed by the early loss of primary teeth (21.7%) and insufficient arch space. The present study is the first to assess the prevalence of delayed eruption of the permanent upper central incisors on a Saudi population. Boys were found to have more prevalence of delayed eruption of the permanent upper central incisors compared to girls. Clinicians should be aware of such a condition as early diagnosis of delayed eruption is essential for providing optimal dental care.

Knowledge, Attitudes, and Practices Toward COVID-19 in a Saudi Arabian Population: A Cross-Sectional Study.

Background Preventative measures are necessary to control a pandemic such as coronavirus disease 2019 (COVID-19), and different platforms to communicate guidelines have varying levels of effectiveness. Objective At the time of this study, there were no published studies investigating knowledge, attitudes, and practices related to COVID-19 within the Saudi population. Therefore, this study aims to address this gap in current knowledge and provide baseline data to the government and other health associations for preventive measurements for future outbreaks. Methods This study was conducted among the Saudi population using an online questionnaire. The questionnaire assessed the awareness of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) incubation period, the known symptoms of COVID-19, the mode of transmission of SARS-CoV-2, and infection control measures for prevention. Results The study included 6000 participants. Most respondents (84.93%) of the population reported awareness of the virus, 78.78% reported a belief that the virus leads to death, 89.47% reported a belief that 14 days is the incubation period, and 93.73% were aware of the possibility of asymptomatic carriers. Conclusions The Saudi population is aware of the attitudes and practices of prevention as well as the mode of transmission. The efforts by the Ministry of Health were effective in increasing awareness among the Saudi population toward COVID-19.
