Coronavirus disease 2019 (COVID-19) is a serious worldwide threat presented by a broad range of symptoms, from mild flu to severe pneumonia. A rising number of atypical infections have been reported. Thus, scientists and clinicians are doing hard work to unravel scientific knowledge about this novel pandemic.
The aim of the present work was to highlight the oral manifestations which could be observed in mild-to-moderate cases of COVID-19.
A questionnaire survey was performed on 665 Egyptian patients who were confirmed COVID-19-positive based on the polymerase chain reaction (PCR) test. After applying the exclusion criteria, cases with mild-to-moderate symptoms were included in the study. The questionnaire consisted of 4 sections. The 1st section included demographic data, smoking, alcohol consumption, and general health status. The 2nd section contained questions regarding the oral hygiene status of the patients, and additionally a question about the hygienic measures they took while being infected with COVID-19. The 3rd section included questions about the most commonly reported COVID-19 symptoms the patients suffered from. The 4th section included questions that referred to the oral manifestations the patients complained of while being infected with COVID-19.
A total of 573 patients were included in this survey. It was reported that 71.7% of COVID-19 patients presented with some oral manifestations at a level of significance, with variable incidence - oral or dental pain (23%), pain in jaw bones or joint (12.0%), halitosis (10.5%), ulcerations (20.4%), and xerostomia (47.6%). Some patients (28.3%) showed 2 or 3 manifestations simultaneously.
It was proven that mild-to-moderate cases of COVID-19 infection are associated with oral symptoms, and thus the significance of dental examination of patients with communicable diseases should be emphasized.
新型冠状病毒病 2019（COVID-19）是一种严重的全球性威胁，其症状广泛，从轻度流感到严重肺炎不等。据报道，越来越多的非典型感染病例。因此，科学家和临床医生正在努力揭开关于这种新型大流行的科学知识。
本研究旨在强调在 COVID-19 轻症至中度病例中可能观察到的口腔表现。
对 665 名基于聚合酶链反应（PCR）检测确诊为 COVID-19 阳性的埃及患者进行了问卷调查。应用排除标准后，将轻症至中度症状的病例纳入研究。问卷分为 4 个部分。第 1 部分包括人口统计学数据、吸烟、饮酒和一般健康状况。第 2 部分包含有关患者口腔卫生状况的问题，以及他们在感染 COVID-19 时采取的卫生措施的问题。第 3 部分包括患者最常报告的 COVID-19 症状的问题。第 4 部分包括患者在感染 COVID-19 时抱怨的口腔表现的问题。
本调查共纳入 573 例患者。报告称，71.7%的 COVID-19 患者出现了一些口腔表现，具有不同的发病率——口腔或牙齿疼痛（23%）、颌骨或关节疼痛（12.0%）、口臭（10.5%）、溃疡（20.4%）和口干（47.6%）。有些患者（28.3%）同时出现 2 种或 3 种表现。
证明轻度至中度 COVID-19 感染与口腔症状有关，因此应强调对传染病患者进行牙科检查的重要性。
