    BACKGROUND: Medical professionals, especially dental professionals, have been adversely affected by the pandemic of COVID-19 due to an increased chance of exposure to patients because of close contact during treatments.

    OBJECTIVES: This study aimed to evaluate knowledge about the disease and assess ways of precautions to be taken during the pandemic.

    METHODS: A questionnaire was developed and registered at Google Forms. The study population included dental practitioners, working in hospitals and clinics. A total of 495 dental practitioners from 14 different countries across the world responded. Most dentists were aware of the required modifications in the management of patients. The points allotted for each correct/best answer by participants for a group of questions regarding each component (Knowledge, Perceptions, and Practices) were added/summed to generate an overall score for each of the three components.

    RESULTS: Both univariate and multivariate analysis employed for the evaluation of results. Moreover, the total practice score was significantly associated with gender and sector of practice. Multivariable analysis model using multiple linear regressions was formulated by including those variables which were significant at the univariate stage. Hence, the practice sector was the only variable found to be significantly associated with the total knowledge score (p-value

    The present study aimed to analyze mid horizontal facial third proportions, those being the interpupillary, inner intercanthal, and bizygomatic distance modified with golden proportion, The Preston proportion, golden percentage and 70% recurring esthetic dental proportion were used for determining maxillary anterior teeth width. A total of 230 participants took part in this study. The front dental and facial photographs along dental stone cast which were converted to three-dimensional (3D) models were used for evaluation. The mid horizontal facial third proportions showed no significant relationship with maxillary anterior teeth width without modification with dental proportions. Whereas, with modification, no statistically significant difference was found between inner-intercanthal distance by golden percentage and width of central incisors. The bizygomatic distance was greater than intercanine distance. While the interpupillary distance by golden proportion was found to be consistent with intercanine distance in female participants. The modified anterior teeth width was significantly different from measured values, when determined by using the three mid facial proportions with Preston and 70% recurring esthetic dental (RED) proportion. Furthermore, the measured width of maxillary anterior teeth showed no difference when plaster dental casts widths were compared with 3D models. The interpupillary, inner-intercanthal, and bizygomatic distance should not be directly used to determine maxillary anterior teeth width. While maxillary anterior teeth width can be determined by modifying the inner inter-canthal distance with golden percentage and interpupillary distance with golden proportion. Moreover, the midfacial third proportions modified with Preston and 70% recurrent esthetic dental proportion were found to be unreliable for the determination of maxillary anterior teeth widths.
