At present, it is very important to identify the available literature regarding the use of masks and respirators by analyzing their historical evolution in the medical field. In addition, consideration should be given to the major filtering characteristics of those most used due to the current SARS-CoV-2 pandemic. Therefore, the purpose of this literature review is to describe the qualitative evolution that facemasks and respirators have undergone along with their different characteristics.
This literature review was conducted between September and December 2020. Articles were identified from PubMed Central, Scopus, and Web of Science. The following keywords were used "COVID-19," "dentistry," and "masks." These MeSH terms were combined with the Boolean operators "AND" and "OR."
We found 36 articles in PubMed Central, 21 in Scopus, and 17 in Web of Science, which included reviews, clinical, descriptive, and experimental trials.
The emergence of new pathogens leads to continuous improvement in masks and respirators. It was determined that for the dental field, respirators with filtration characteristics greater than 95%, such as FFP3, N100, N95, and KN95, are indicated in addition to their decontamination and reuse processes.

Some patients reportedly present with oral manifestations of coronavirus disease 2019 (Covid-19). It is unknown if this is due to the virus itself or a side effect of treatment; however, severe acute respiratory syndrome coronavirus 2 has been shown to have a predilection for angiotensin-converting enzyme receptors that are present in the respiratory tract, oral mucosa, tongue, and salivary glands, causing alterations in taste and smell. Therefore, the objective of this review was to present the future challenges of Covid-19 and oral manifestations in daily dental practice through a literature review.
Scientific evidence in the databases Scopus and PubMed was searched using the Boolean operators. Articles published in Spanish and English between January and December 2020 were included.
Of the 89 articles found in Scopus, 69 were of the open access type and 20 were in the "others" category; only 22 scientific articles were found in PubMed.
It is important to take into account these clinical manifestations such as loss of taste and smell in order to detect the disease. Good oral hygiene is also recommended as a preventive measure to reduce viral load, which considerably reduces the probability of infecting other people who are in contact with the infected patient.

The study aims at reviewing Myanmar's current situation to consider an improved oral health system and at promoting the oral health status of the Myanmar population.
This review was conducted using the World Health Organization's (WHO's) six building blocks of the health system oral health-care service delivery, dental workforce, oral health information system, essential medicine, health financing, and leadership and governance. The review was established on scientific articles and documents and information from reliable government and nongovernment organizations' websites.
According to the National Oral Health Survey (2016-2017), the prevalence rate of untreated caries in six-year-old Myanmar children (84.1%), and in the 35-44 and 65-74 age group (above 40%) is high, which reflects a low utilization of oral health-care services. The dentist to population ratio is approximately 116,000 There are around 5,000 dentists and 400 trained dental nurses in Myanmar, and only about 1,000 dentists serve in government sectors. The inequalities in dental health care are compounded by a limited dental workforce and inequality of dentists between the public and private sectors in Myanmar. In the last National Health Plan (NHP, 2006-2011), the Myanmar government's funding for required dental equipment and materials in each dental unit (around 5726 USD) has been considered inadequate. The current expenditure is not transparent. The other challenges are an insufficient supply of dental materials and instruments to all public dental sectors and a lack of oral health-care infrastructure.
Such findings suggest a pressing need to address the effective oral health-care system and decree the specific goals for the Myanmar population's oral health.

Most of these tumors are primary or de novo GBs that manifest rapidly with initial presentations such as headache, new-onset epileptic seizure, focal neurological deficits, and altered mental status. The typical radiological features of GB include strong contrast enhancement, central necrosis, and edema with mass effect. Herein, we describe two cases of primary GB - two women aged 60 and 51 years who were diagnosed with GB 3.5 and 4 months, respectively, after their initial admission. These patients presented with right-sided headaches, and their neurological examination was within the normal limits. Their initial radiological investigations revealed no suspicious lesions, either on T1-weighted or T2-weighted magnetic resonance (MR) images. The 60-year-old patient was readmitted with persistent headache, and her T1-weighted MR images revealed a well-demarcated mass lesion in the right temporal lobe with strong contrast enhancement. Moreover, the T2-weighted MR images revealed closed sulci and swollen midline structures because of edema. Buloxibutid The 51-year-old patient was readmitted with persistent headache, and her MR image revealed a mass lesion with heterogeneous contrast enhancement and necrosis on T1-weighted images and hyperintense areas with severe edema on T2-weighted images. The patients underwent craniotomy and gross total tumor resection. Notably, in both cases, the lesions were pathologically diagnosed as GB. Therefore, it should be borne in mind that only persistent headache could be a sentinel sign of GB before it becomes radiologically visible, thereby emphasizing the need for follow-up imaging studies at short intervals.
