Validation of Modified Hertel Exophthalmometer.

STUDY DESIGN: This is a correlation study. OBJECTIVE: The objective was to obtain normative values from modified Hertel exophthalmometer, to compare difference in values between modified and standard Hertel exophthalmometer and to statistically analyze for correlation. METHODS: The study to validate the modification done to Hertel exophthalmometer was performed at the Department of Oral and Maxillofacial Surgery at our institute. Informed consent was obtained from patients; measurement in 100 volunteers was made with Hertel and modified Hertel exophthalmometer by a single observer, and the measurements taken by the 2 devices were tabulated along with variables such as age and gender. Data were collected and statistical analysis was performed to compare and correlate the values between standard and modified exophthalmometer. Differences of ocular protrusion values in gender and age were also calculated. RESULTS: There has been no statistically significant difference in the normative data between standard Hertel and modified Hertel exophthalmometer and in relation to age and gender. CONCLUSIONS: The modification of the Hertel exophthalmometer is validated and can also be used for relative exophthalmometry to assess the need for treatment and to evaluate the globe position and orbital volume intraoperatively. The proposed modification of the instrument allows it to be used in cases when one of the lateral orbital walls is fractured or displaced due to trauma.

A Review of Prolonged Post-COVID-19 Symptoms and Their Implications on Dental Management.

The available data regarding the short and long-term consequences of COVID-19 is still insufficient. This narrative review aims to provide information on the prolonged COVID-19 symptoms in recovered patients and their implications during dental management. Additionally, this manuscript highlights the oral manifestations of COVID-19 and its management. A systematic search was conducted in PubMed, Embase, Cochrane Library and Web of Science databases, WHO and CDC websites, and grey literature was searched through Google Scholar. Clinical articles (clinical trials, case-reports, cohort, and cross-sectional studies) were included, reporting prolonged post-COVID-19 symptoms. Although COVID-19 is an infectious disease primarily affecting the lungs, its multi-organ involvement is responsible for several prolonged symptoms, including oral implications. In recovered patients with prolonged COVID-19 symptoms, considerations for providing dental treatment has to be made as they can present with assortment of symptoms. These prolonged post-COVID-19 symptoms can affect the delivery of the required dental treatment. Hence, the recommendations proposed in this narrative review can be a useful starting point to aid dental teams providing adequate care for such recovered patients.
