Abstract

Since the beginning of the COVID-19 pandemic, the number of people wearing masks in everyday life has increased. At the same time, there has been a noticeable rise in the amount of patients with bad breath (foe-tor ex ore), gingivitis, caries, and xerostomia. The appearance of these symptoms and diseases caused by wearing a mask is designated by the term mask mouth. The aim of this article is to establish the link between wearing protective masks and deteriorating oral health. From the conducted research, it has been es-tablished that wearing a surgical mask over a long period of time leads to reduced air exchange in the mask and "recycling" of exhaled air. This leads to inhalation of air with increased CO2 content and increase in pCO2 in the blood, which is subsequently compensated by rapid and deep breathing in most cases through the mouth. The goal is to exhale the accumulated CO2. As the mask reduces air exchange, the level of CO2 in the mask remains relatively high. Prolonged breathing through the mouth often leads to xerostomia. Saliva is known to have protective functions against the development of bacteria in the oral cavity through its an-tibacterial properties. Xerostomia can be a prerequisite for the development of various diseases of bacterial origin, such as gingivitis. Furthermore, oral respiration leads to an increase in temperature and CO2 in the air in the mask and a decrease in pH in the oral cavity, which are optimal conditions for biofilm formation, plaque buildup, development of most bacteria, e.g., S. mutans, which is the main cause of caries.Copyright © 2022, Bulgarian-American Center.

戴防护口罩与口腔健康不良的关系
自2019冠状病毒病大流行开始以来,日常生活中戴口罩的人数有所增加。与此同时,患有口臭(口臭)、牙龈炎、龋齿、口干症的患者也明显增加。这些由戴口罩引起的症状和疾病的出现被称为口罩口。本文的目的是建立佩戴防护口罩与口腔健康恶化之间的联系。从所进行的研究中可以确定,长时间佩戴外科口罩会导致口罩内的空气交换减少,并导致呼出的空气“再循环”。这导致吸入二氧化碳含量增加的空气和血液中二氧化碳分压增加,随后在大多数情况下通过口腔快速深呼吸来补偿。目标是呼出累积的二氧化碳。由于面罩减少了空气交换,面罩内的二氧化碳含量仍然相对较高。长时间用嘴呼吸经常会导致口干症。众所周知,唾液通过其抗细菌特性对口腔内细菌的发展具有保护作用。口干症可能是各种细菌性疾病发展的先决条件,如牙龈炎。此外,口腔呼吸导致口罩内空气中的温度和二氧化碳升高,口腔内pH值降低,这是生物膜形成、菌斑积聚和大多数细菌(如变形链球菌)发育的最佳条件,变形链球菌是导致龋齿的主要原因。版权所有©2022,保加利亚-美国中心。版权所有。
