    AIM: The study aims to determine the frequency of positioning errors, record the number of diagnostically inappropriate images, and assess the quality of panoramic radiographs.

    MATERIALS AND METHODS: In this study, a total of 2629 patients for whom orthopantomogram were selected out of 3900 new patients between August 2020 and June 2021. The positioning errors of the radiographs were evaluated and categorized into ten groups. The quality of the radiographs is further assessed as "Excellent," "Diagnostically Acceptable," and "Diagnostically Unacceptable."

    RESULTS: Out of the total radiographs, 32.8% had no errors, and 77.2% of the radiographs had one or more positioning errors. The radiographs were analyzed in detail, and the errors found in the panoramic radiographs were recorded. The most common positioning error observed in the radiograph was error 8, failure to place the tongue close to the palate.

    CONCLUSION: The results and evaluation inferred that attention to patient positioning and focusing on reducing diagnostically indecent images could improve the quality of panoramic radiographs. Proper instructions to the patient, patient preparation, appropriate positioning of the patient, and the technician's skill plays a vital role in reducing diagnostic errors in Panoramic Radiography.

    The long-term solution to managing the current COVID-19 pandemic is through mass immunization of the population. However, uncertainty or unwillingness to receive the vaccine could be a barrier in attaining sufficient vaccine coverage. Therefore, understanding the psychology of the population towards the vaccines against COVID-19 is of paramount importance. Our study was aimed at determining the predictors of COVID-19 vaccine intention in the Saudi Arabian population. A structured questionnaire guided by the 'Report of the SAGE working group on vaccine hesitancy' was administered during a span of two months among the general population from all administrative regions of Saudi Arabia, proceeding the launch of the vaccination campaign. In total, 879 out of 1600 subjects responded and completed the survey (response rate 54.9%). About 56 percent of the participants intended to be vaccinated. The predictors of a higher intention to vaccinate included those 50 years of age or older, male subjects, people suffering from systemic disease/s, subjects who were not previously infected with COVID-19, those who follow the updates about COVID-19 vaccines, and adults with a higher level of anxiety about contracting coronavirus (p < 0.05). Results from our study and other similar studies can aid policy makers and stakeholders in planning effective strategies based on the changing behavior of the population.
  3. Fulltext COVID-19 Vaccine Intention among Healthcare Workers in Saudi Arabia: A Cross-Sectional Survey

    The COVID-19 pandemic has caused largescale morbidity and mortality and a tremendous burden on the healthcare system. Healthcare workers (HCWs) require adequate protection to avoid onward transmission and minimize burden on the healthcare system. Moreover, HCWs can also influence the general public into accepting the COVID-19 vaccine. Therefore, determining COVID-19 vaccine intention among HCWs is of paramount importance to plan tailor-made public health strategies to maximize vaccine coverage. A structured questionnaire was administered in February and March 2021 among HCWs in Saudi Arabia using convenience sampling, proceeding the launch of the vaccination campaign. HCWs from all administrative regions of Saudi Arabia were included in the study. In total, 674 out of 1124 HCWs responded and completed the survey (response rate 59.9%). About 65 percent of the HCWs intended to get vaccinated. The intention to vaccinate was significantly higher among HCWs 50 years of age or older, Saudi nationals and those who followed the updates about COVID-19 vaccines (p < 0.05). The high percentage (26 percent) of those who were undecided in getting vaccinated is a positive sign. As the vaccination campaign gathers pace, the attitude is expected to change over time. Emphasis should be on planning healthcare strategies to convince the undecided HCWs into accepting the vaccine in order to achieve the coverage required to achieve herd immunity.
