ABSTRACT
Objectives: Varicella is common infectious disease mainly in childhood, usually is a mild, self-limited illness and complications are usually rare. The incubation period for this disease is generally 14- 16 days but may vary from 7 to 21 days. Varicella in the adults with comorbidities or immunosuppressed children may be severe and prolonged with complications. Method(s): A case report of a 6-year-old girl hospitalized for new-onset manifestations of disseminated vesicular exanthema, the manifestations of which occurred mainly on the chest, back, capillitium, oral cavity, and genital area. The child was suffering from abdominal, knee and lumbosacral pain at that time. The patient's history revealed that 10 days prior to the cutaneous manifestations, she had influenza with bronchopneumonia requiring oxygen therapy, steroids and antibiotics. Result(s): The condition progressed within 48 h, complicated by the development of multi-organ failure, coagulopathy with the development of disseminated intravascular coagulopathy over the course of antiviral, antibiotic and antifungal therapy. Laboratory parameters included high elevation of C-reactive protein, il-6, leukocytosis, neutrophilia and highly elevated liver enzymes. Varicella infection was confirmed by detection of herpes zoster virus - polymerase chain reaction (PCR) from vesicles. The patient received intravenous immunoglobulin therapy at a dose of 2 g/L and fresh frozen plasma, thrombocyte concentrate. The girl was intubated with analogization. Laboratory parameters subsequently revealed high anti CoV-2 positivity, high CoV-2 IgG positivity and negative CoV-2 IgM. The patient's condition did not preclude the course of multisystem inflammatory syndrome in children (MIS-C) corticosteroids were added to the treatment at a dose of 1 mg/kg weight. Patient's condition stabilized after 1 month. Discussion(s): Our case report presents an example of fulminant complicated life-threatening course of varicella. Even in common respiratory infections, we must think about the risk and consequences of coinfections and post-infectious complications such as in our case especially influenza and COVID-19.
ABSTRACT
The respiratory pump that provides pulmonary ventilation includes the respiratory center, peripheral nervous system, chest and respiratory muscles. The aim of this study was to evaluate the activity of the respiratory center and the respiratory muscles strength after COVID-19 (COronaVIrus Disease 2019). Methods. The observational retrospective cross-sectional study included 74 post-COVID-19 patients (56 (76%) men, median age - 48 years). Spirometry, body plethysmography, measurement of lung diffusing capacity (DLCO), maximal inspiratory and expiratory pressures (MIP and MEP), and airway occlusion pressure after 0.1 sec (P0.1) were performed. In addition, dyspnea was assessed in 31 patients using the mMRC scale and muscle strength was assessed in 27 of those patients using MRC Weakness scale. Results. The median time from the COVID-19 onset to pulmonary function tests (PFTs) was 120 days. The total sample was divided into 2 subgroups: 1 - P0.1 <= 0.15 kPa (norm), 2 - > 0.15 kPa. The lung volumes, airway resistance, MIP, and MEP were within normal values in most patients, whereas DLCO was reduced in 59% of cases in both the total sample and the subgroups. Mild dyspnea and a slight decrease in muscle strength were also detected. Statistically significant differences between the subgroups were found in the lung volumes (lower) and airway resistance (higher) in subgroup 2. Correlation analysis revealed moderate negative correlations between P0.1 and ventilation parameters. Conclusion. Measurement of P0.1 is a simple and non-invasive method for assessing pulmonary function. In our study, an increase in P0.1 was detected in 45% of post-COVID-19 cases, possibly due to impaired pulmonary mechanics despite the preserved pulmonary ventilation as well as normal MIP and MEP values.Copyright © Savushkina O.I. et al., 2023.
ABSTRACT
Introduction: Universities represent important Centers for public health assistance. However, in the context of the COVID- 19 pandemic, most Brazilian universities have suspended their academic activities and outpatient care. Objective(s): Describe how the Teleconsultation Program in Oral Medicine of the School of Dentistry, Brazil, remotely contributes to counseling dentistry on diagnosing oral lesions and providing guidance on treating patients in the North Macro-region of Minas Gerais state. Material(s) and Method(s): Teleconsulting takes place remotely;the professional sends by smartphone, via WhatsApp, the case report, clinical images, and complementary exams, if appropriate. Concerning this, the specialist team analyzes the clinical case and returns it to the professional sender, providing information and suggestions on the oral lesions' diagnostic assessment and clinical management. Result(s): Since the beginning of the program, in 19 months, dentists from 40 municipalities were counseled, which resulted in 287 teleconsultations;from these cases, 103 cases were conducted face-to-face consultations in our Oral Diagnosis Service, and 38 cases were hypothesized as malignant lesions in the oral cavity and had their medical treatment conducted and followed by a multidisciplinary team, when appropriate. Conclusion(s): Teleconsultation Program represents an important tool to strengthen the communication between professionals of public health, improve health work processes, and promote better clinical guidance in Oral Medicine.
ABSTRACT
The oral cavity houses a large number of microorganisms that are potential pathogens, such as cytome-galovirus, hepatitis B virus (HBV), hepatitis C virus, herpes simplex virus types 1 and 2, human immuno-deficiency virus, mycobacterium tuberculosis and currently with the appearance of the SARS COV-2 that causes covid-19, the dental community must take stricter measures in its protection protocols against diseases. To evaluate its germicidal efficacy, ultraviolet light was applied with different exposure times on the alginate dental impressions, immediately after having taken the impression, which when it came into contact with the oral cavity of the patient is contaminated. As a result, a decrease in size and quantity of the bacterial colonies was observed in most of the samples in which the UV LED light was applied at 10 and 15 minutes of exposure. Some samples showed less bacterial growth even after 5 minutes of exposure. All this confirms its germicidal capacity thanks to its 245 nm ultraviolet spectrum that affects the DNA and RNA chain of microorganisms since it is the wavelength of maximum absorption of its molecule, eliminating its reproductive and survival capacity. The advantages it offers such as its small size, easy to handle and install, that it does not require constant maintenance, low acquisition cost;its constant high intensity light that does not generate any increase in temperature, makes it an excellent disinfectant auxiliary that can be incorporated into dental clinics.Copyright © 2023, Ediciones Avances S.L..

ABSTRACT
Introduction: Several studies have evaluated the occurrence of oral lesions and changes in sensory functions in patients positive for COVID-19. Objective(s): To evaluate the manifestations of COVID-19, emphasizing olfactory and gustatory changes, xerostomia, and oral lesions. Material(s) and Method(s): A cross-sectional and observational study was conducted. Approved by the Institutional Ethics Committee (#46151121.6.0000.5141). All patients were diagnosed by reverse transcription-polymerase chain reaction assay (RT-PCR) and considered to have mild symptoms, according to the latest WHO joint report. The patients were evaluated at a reference Service for COVID-19 in Minas Gerais, Brazil. The oral cavity was evaluated for each patient on the second and seventh days. Result(s): A total of 414 patients older than 18 years were evaluated. One hundred thirty-nine presented at least one of the studied conditions, oral lesions (19.08%) were the most frequently observed, followed by gustatory disorders (18.11%), xerostomia (14.25%), and olfactory dysfunction (14%). Among the oral lesions, there were various anatomical locations and clinical presentations. The occurrence involving lips and tongue represented 49 oral lesions, the most prevalent being, respectively, ulcerations (n=51), candidiasis (n=8), and erythema or red plaques (n=7). Fifty patients died. Conclusion(s): This study represents, to date, the largest case series of oral lesions in Brazilian patients with COVID-19, and oral alterations were observed in an expressive percentage of patients with COVID-19. However, it cannot be concluded that SARS-CoV-2 directly causes them.
ABSTRACT
An average person carries 1 to 2 kg of microbes in the alimentary track, including the oral cavity. There are more bacteria in a person's mouth than the total human population in the entire world. Oral health is critical to the general systemic health of an individual. The harmonious co-existence between more than 1000 bacterial species and the host's immune system underpins sustained, long-term homeostasis, the sine qua non of oral health. In a similar manner, global oral health is essential for general population health of the world. Since our last review of this subject in 2019, while significant clinical advances continue, the disparity, lack of prevention, insufficient care, and political unrest have persisted or significantly deteriorated. This review focuses on the following important questions: 1.What is oral microbiome? How to detect, characterize, compare, report, and interpret the results?2.How does oral microbiome affect and respond to local and systemic innate immunity?3.What is the role of oral microbiome in the pathogenesis of diseases of the mouth?4.What are the impacts of oral health or the lack of it at the systemic level?5.Why is oral health important at the population level?6.How can the healthcare providers restore and sustain harmonious co-existence between host and oral microbiome?Copyright © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.

ABSTRACT
Background: Infancy is an important developmental period when the human microbiome is shaped. Given links between young age at antiretroviral treatment (ART) initiation and smaller persisting viral reservoirs, we hypothesized that earlier ART initiation may leave distinct microbial signatures in the oral cavity detectable in children living with HIV (CLWH). Method(s): Oral swab samples were collected from 477 CLWH and 123 children without HIV at two sites in Johannesburg, South Africa. CLWH had started ART < 2 years of age with 60% starting < 6 months of age. Most were wellcontrolled on ART at a median of 10 years of age when the swab was collected. Controls were age-matched and recruited from the same communities. Sequencing of the V4 amplicon of the 16S rRNA gene was done using established protocols. DADA2, decontam, and phyloseq were used for sequence inference, contaminant removal, and subsequent analyses. All p-values were adjusted for multiple testing using Benjamini-Hochberg false discovery rate method. Statistical analyses were performed with R. Result(s): CLWH had lower alpha diversity than uninfected children (Shannon index p< 0.0001). Genus-level abundances of Granulicatella, Streptococcus and Gemella were greater and Neisseria and Haemophilus were less abundant among CLWH compared to uninfected children. Associations were strongest among boys. There was no evidence of attenuation of associations with earlier ART initiation. In fact, decreased bacterial diversity and differences in taxa abundances in CLWH versus controls were consistent regardless of whether ART was started before or after 6 months of age. Shifts in genus-level taxa abundances relative to uninfected controls were most marked in children on regimens containing lopinavir/ritonavir;with few shifts seen if on regimens containing efavirenz. Conclusion(s): A distinct profile of less diverse oral bacterial taxa was observed in school-age CLWH on ART versus uninfected age-matched children suggesting persisting interference of HIV and its treatments on microbiota in the mouth. Any effects of earlier ART initiation were not detectable at this age. Studies of treated adults with HIV have observed similar shifts in taxa abundances. Oral microbiota have been linked to salivary cytokine levels with associations between Granulicatella and IL-8 and Neisseria and IL-6. Declines in Neisseria abundances in oral samples have been associated with more severe outcomes in influenza and COVID-19.
ABSTRACT
Introduction. The connection between the health of the oral cavity and general health is well known, because oral diseases can impair general health, but the health of the oral cavity can also be impaired due to the existence of a systemic disease. The structures of the oral cavity can be affected directly by the disease or indirectly due to the influence of drugs or due to the patient's behavior. Oral manifestations affect hard dental tissues, supporting tissues and oral mucosa. The changes that occur can lead to pain and discomfort, cause concern for the child and parents, and can be completely asymptomatic. Doctors of dental medicine are often the first to suspect the presence of a disease during a routine examination, because the area of the oral cavity is easily accessible for early detection of pathological changes. That way, they can directly influence the course and therapy of the systemic disease by early recognition and referring the patient to further tests. Aim of the lecture is to present oral manifestations of gastrointestinal diseases, diabetes, blood diseases, bacterial diseases and viral diseases with a special focus on COVID-19.
ABSTRACT
The corona virus disease 2019 (COVID-19) caused by severe acute respiratory syndrome corona virus 2 (SARSCoV-2), first detected in Wuhan, Hubei province of China, has emerged rapidly as a health crisis that has challenged health systems and health professionals all over the world. Transmission occurs primarily through droplet spread or contact routes. Due to these characteristics dental staff and dental practitioners are considered to be at the highest risk of acquiring SARS-CoV-2 infection because of their prolonged face to face exposure to patients and exposure to respiratory secretions and aerosols produced during procedures like ultrasonic scaling and cavity/access preparation using a high-speed air rotor with water jet cooling systems. Antiseptic mouthwashes have been widely used as a standard measure before routine dental treatment, especially preoperatively. They have an essential role in reducing the number of microorganisms in the oral cavity. Hence, present review of literature provides details on role of mouthwash in prevention of Covid-19 transmission.Copyright © 2020 Ubiquity Press. All rights reserved.
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.

ABSTRACT
Introduction: An urgent dental care centre (UDCC) was set up at Queen Mary's Hospital in Sidcup, in response to the COVID-19 pandemic. Alongside the reporting of clinical outcomes, it is important to determine the success of a service from a patient's perspective. The aim of this study was to ascertain patient reported outcome measures (PROMs) and patient reported experienced measures (PREMs) of our service. Method(s): The Oral Health Impact Profile 14 (OHIP-14) tool was used to assess the Oral Health-Related Quality of Life (OHRQoL) of patients, and completed before and after attending our UDCC for treatment. Patients were also asked to complete a patient satisfaction questionnaire. Result(s): 146 patients were recruited for our study, with 95 patients completing the OHIP-14 questionnaires pre- and post intervention at our UDCC and 136 patients completing a patient satisfaction questionnaire. A statistically significant reduction in OHIP score when comparing pre- and post-intervention was found across all OHIP-14 domains. The mean positive response rate (strongly agree or agree) for the patient satisfaction questionnaire was 97.1%. Conclusion(s): A significant improvement in OHRQoL was found after treatment at our UDCC, with the majority of patients reporting a positive experience. We conclude that PROMs and PREMs are vital tools to assess service efficacy, help with the planning of service provision and should remain at the forefront even during a crisis such as the COVID-19 pandemic.Copyright © 2021
ABSTRACT
Public health officials are gravely concerned about the harm that viral illnesses continue to pose to humanity, various viral outbreaks, including the Middle East Respiratory Syndrome Corona-Virus (MERS-CoV), H1N1 influenza, the severe acute respiratory syndrome coronavirus (SARS-CoV-2) and SARS CoV-2 or COVID-19 that struck the globe in December 2019. A wide range of COVID-19 oral symptoms, such as ulceration, blisters, enanthems, hemorrhagic sores and cheilitis. Aim(s): to investigate the prevalence of oral symptoms amongst COVID-19 patients due to the disease's aggressive nature and diverse symptomatology and to assess the impact of oral health conditions on COVID-19 disease severity in a sample of Iraqi people. Material(s) and Method(s): a cross-sectional study was conducted on (200) patients in total, (81) male and (119) female, who were identified as SARS-COV2 patients. Result(s): COVID confirmed patients were involved in the present study with mean age (36.69+/-17.22) years & age range of (16-78) years. at least one of the oral manifestations was present in 72.5% of the patients, while about 27.5% did not experience any oro-facial symptoms. The oral symptom with the highest prevalence was dry mouth 50% followed by gustatory dysfunction 37% then burning mouth sensation 22.5% after that the oral pain 17%;myofacial pain 15.5 %;stomatitis\mucositis 14.5%;the prevalence of aphthous lesions, fissural cheilitis and tongue depapillation were at the same percentage which was 9.5%;then candidiasis 7.5%;the least prevalent oral symptoms was gingival bleeding at percentage of 2.5%. Conclusion(s): COVID-19 has a noticeable effect on oral cavity, there was a correlations between some general and orofacial manifestations of COVID-19.Copyright © 2023, Codon Publications.

ABSTRACT
The oral cavity, like the lungs, is often referred to as the <<ecological niche of commensal, symbiotic, and pathogenic or-ganisms,>> and the emigration and elimination of microbes between them are constant, ensuring a healthy distribution of saprophytic microorganisms that maintains organ, tissue, and immune homeostasis. The prolonged hospital stays due to COVID-19 complications, cross-infection, oxygenation therapy through the mask or incubation, and long-term intravenous infusions limit the patient's ability to care about the oral cavity, regularly clean teeth, floss interdental, etc., which creates extremely favorable conditions for colonization by aerobic and anaerobic pathogens of the oral cavity and periodontal pockets and leads to the rapid progression of chronic generalized periodontitis in this category of patients in the future. The goal of the study was to assess the state of the microbiome of the periodontal pockets of dental patients in the post-covid period. Methods. The object of the study was 140 patients with generalized periodontitis of the I and II stages of development in the chronic course (GP), among which 80 patients had coronavirus disease in the closest past. The patients were randomized by age, sex, and stage of GP development. The diagnosis of periodontal disease was established according to the classification by Danilevskyi. The bacteriological material for aerobic and facultative anaerobic microflora and yeast-like fungi was collected from periodontal pockets with a calibrated bacteriological loop and immediately seeded on blood agar. Results. Significant qualitative and quantitative changes in the nature of the oral microbiocenosis were observed in patients with GP after the recent coronavirus disease, compared with similar patients who did not suffer from COVID-19. We have noticed almost complete disappearance of bacteria that belong to the transient representatives of the oral microflora such as Neisseria, corynebacteria (diphtheria), micrococci, and lac-tobacilli. The main resident representatives of the oral microflora, i.e., alpha-hemolytic Streptococci of the mitis group, were found in all healthy individuals and patients of groups A and C, but in 30.0 +/- 4.58% of patients in group B, alpha-hemolytic streptococci in the contents of periodontal pockets are present in quantities not available for detection by the applied method (<2.7 lg CCU/mL). In terms of species, Streptococcus oralis and Streptococcus salivarius are more characteris-tic in gingival crevicular fluid in healthy individuals (93.8% of selected strains). In 68.4 +/- 3.32% of patients in group A, 64.0 +/- 3.43% of patients in group B, and 67.5 +/- 3.76% of patients in group C, the dominant species were Streptococcus gordonii and Streptococcus sanguinis (p<0.01), which increased pathogenic potential as they produce streptolysin-O, inhibit complement activation, bind to fibronectine, actively form biofilms on the surface of tooth enamel and gum epithelial surface, and can act as an initiator of adhesion of periodontal pathogens. The other representatives of the resident microflora of the oral cavity - Stomatococcus mucilaginosus and Veillonella parvula for the patients of group C are also found in periodontal pockets with a significantly lower index of persistence and minimal population level. In the post-covid period, both the population level and the frequency of colonization of periodontal pockets by Staphylo-cocci and beta-hemolytic Streptococci decreases rapidly. For these patient groups, unlike for those that did not suffer from COVID-19, we did not find any case of colonization with Staphylococcus aureus, as well as beta-hemolytic Streptococci and Epidermal staphylococcus were also absent. The most characteristic in the post-covid period is a decrease in the proportion of alpha-hemolytic Streptococci, an increase in the proportion of yeast-like fungi of Candida species, as well as the appearance of a significant number of gram-negative rod-shaped bacteria (Enterobacteria and Pseudomonads). In periodontal patien s, the microbial count is approximately 2 orders of magnitude lower than in those with GP who did not suffer from COVID-19 (p<0.05). Conclusions. The overpassed coronavirus disease due to intensive antibiotic therapy leads to a marked decrease in the number of viable saprophytic microorganisms in the periodontal pockets of patients with GP. In the post-covid period for the patients with GP, there is a decrease in the level of colonization of periodontal pockets by species of resident oral microflora - alpha-hemolytic Streptococci, reduction of resident micro-organism's species, and almost complete disappearance of transient microflora. On the other hand, the frequency of colonization of periodontal pockets by fungi species, enterobacteria, and pseudomonads significantly increases. There are more expressed disorders in the periodontal pocket's microbiome for the patients with a severe and complicated course of coronavirus disease, such as post-covid pulmonary fibrosis, which requires reconsideration of approaches to therapeutic and pharmacological treatment in this category of patients.Copyright © 2022, Zabolotny Institute of Microbiology and Virology, NAS of Ukraine.

ABSTRACT
OBJECTIVES Teledentistry is a telematics approach validated in the literature that allows the remote diagnosis and management of various oral health problems, avoiding direct face-to-face contact with the patient. This study aims to present a review of the scientific literature to analyze in which fields of pediatric dentistry teledentistry has found application and with what results;in addition, a case of unconventional oral candidiasis in a child, diagnosed and managed through the use of teledentistry during the SARS-CoV-2 pandemic in April 2020, is presented. MATERIALS AND METHODS The literature search was performed through PubMed (using keyword and MeSH terms), Scopus and Embase databases, evaluating observational, interventional, case reports and case series studies, published in English between 1999 and 2021 and conducted in children. The clinical case presented was diagnosed and managed through photographs that the pediatric dentist received from the patient's mother via a multi-platform messaging application. Through the same application, the mother was able to provide informed consent to take care of the patient remotely, after acceptance of possible critical issues regarding teledentistry, and receive a prescription for home treatment of oral candidiasis. RESULTS After exclusion of duplicates and articles that did not meet the inclusion criteria, 14 studies were selected. Teledentistry was applied in four different areas: oral health promotion, with 2 studies examining smartphone applications to improve home oral hygiene, diagnosis/follow-up/treatment in orthodontics with 4 studies, caries and other hard and soft tissue diseases of the oral cavity with 7 studies, and finally dental traumatology with a single study. With regard to the promotion of oral health, two applications for the improvement of home oral hygiene were examined. They showed promise for motivation and education. In orthodontics, the studies evaluated in this review reported that teledentistry is useful and valuable for follow-up and orthodontic consultations that can be obtained quickly;doubts remain regarding expense, intervention time and operator compensation. In addition, remotely supervised interceptive treatment appears to reduce the severity of malocclusions. About caries and other hard and soft tissue diseases of the oral cavity, results indicate that teledentistry can reduce waiting lists and the need for face-to-face examinations. Teledentistry is considered valid, efficient and potentially cost-effective for screening and follow-up of caries, being comparable to traditional clinical examination. Teledentistry has proven to be comparable to clinical examination for the diagnosis of dental trauma. CONCLUSIONS The data collected allow us to conclude that teledentistry, thanks to advances in technology, can be a useful means for pediatric dentists to improve the oral health of young patients and to provide better access to oral health services by effectively replacing face-to-face dentistry in various situations. The presented clinical case confirms the conclusions obtained from the literature search. CLINICAL SIGNIFICANCE Teledentistry can replace face-to-face visits in several areas of pediatric dentistry and ensuring safe care during any future pandemics.Copyright © 2023 EDRA SpA.

ABSTRACT
The human body is inhabited by trillions of diverse microorganisms collectively called "microbiome" or "microbiota". Microbiota consists of bacteria, viruses, fungi, protozoa, and archaea. Microbiome demonstrates multi-faceted effects on human physical and mental health. Per evidence there is a multi-functional interplay between the whole-body microbiome composition on the epithelial surfaces including skin, nasal and oral cavities, airway, gastro-intestinal and urogenital tracts on one hand and on the other hand, the individual health status. Microbiota composition as well as an option to modulate it - together create a highly attractive operation area for the translational bio/medical research with multi-professional expertise and healthcare-relevant output in the framework of predictive, preventive and personalised medicine (PPPM/3 PM). Advanced PPPM strategies implemented in the microbiome area are expected to significantly improve individual outcomes and overall cost-efficacy of healthcare. According to the accumulated research data, corresponding diagnostic and treatment approaches are applicable to primary care (health risk assessment in individuals with sub-optimal health conditions and prevention of a disease development), secondary care (personalised treatment of clinically manifested disorders preventing a disease progression) and tertiary care (making palliation to an optimal management of non-curable diseases). In the current book, we do highlight the implementation potential of the microbiome-relevant research in the framework of predictive diagnostics, targeted prevention and treatments tailored to the individualised patient profile.Copyright © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.
ABSTRACT
Paediatric patients comprise a small proportion of the SARS-CoV-2 infected population. They usually present with mild symptoms, however a small proportion of them may require intensive care due to shock and multi-organ failure related to Paediatric Inflammatory Multisystem Syndrome temporally associated with SARS-CoV-2 (PIMS-TS). This review article summarises the oral mucosal lesions in children with COVID-19 and PIMS-TS. The most common sites affected are the tongue and lips. Commonly reported lesions include cheilitis, dry and red lips, and tongue swelling. This article is of importance to all healthcare professionals involved in the multidisciplinary care for this group of patients.Copyright © 2021 The Authors
ABSTRACT
Background: Oroantral communication can occur due to maxillectomy defects, jeopardizing the integrity and function of oral cavity. It is an interdisciplinary challenge to restore these by surgery and prosthetics since many facets need to be addressed, such as speech, deglutition, mastication, aesthetics and psychological distress. Rationale: Surgical repair of maxillectomy defects is not always achievable due to various reasons such as poor systemic health, advanced age etc. Thus prosthetic rehabilitation becomes the most suitable treatment option. Relevance for Patients: Post COVID-19 mucormycosis has seen a surge in the past two years. It is an opportunistic fungal infection in humans infecting intracranial structures by direct invasion in the blood stream. Fundamental goal of prosthetic rehabilitation is the closure of oronasal communication and restoring it functionally thereby improving quality of life for the patient. CAD/CAM (computer aided design/computer aided milling) technology was employed to fabricate a milled framework for maxillary obturator in the most innovative way using PEEK (Polyether ether ketone). Result(s): PEEK material due to its excellent biocompatibility ensured a light weight prosthesis for the large maxillectomy defect and closure of the patency was achieved by the obturator framework.Copyright © 2022 Authors.

ABSTRACT
Introduction: Coronavirus is a large group of RNA viruses that causes chronic respiratory problems in humans. Severe COVID- 19 acute infection, along with associated therapeutic measures, could potentially contribute to various opportunistic fungal infection, xerostomia linked to decreased salivary flow, ulcerations and gingivitis as a result of impared immune system and susceptible oral mucosa. Aim(s): The aim of the study is to create awareness about post COVID complications in the oral cavity among dental students. Material(s) and Method(s): The sample size of the study was about 100 participants of undergraduate dental students. A set of questionnaires was created by the use of google form software, the data collection software score and represent the participants answer in a pie chart. Result(s): It is clear that 59 % of people were aware about the post COVID complications in the oral cavity.Among the males 38% of people were aware that gingivitis is a post COVID complication. Whereas, among females 19% of people were aware that gingivitis is a post COVID complication. Collectively among males and females, males were more aware about the post COVID complication in the oral cavity. Conclusion(s): The study had concluded that students were moderately aware about the post covid complications in the oral cavity. Copyright © 2022 Wolters Kluwer Medknow Publications.

ABSTRACT
Introduction/Aim: Ludwig's angina is potentially life-threatening, polymicrobial infection of bilateral submandibular and sublingual spaces. Most common organisms isolated from deep neck infections are viridans streptococci, streptococcus anginosus group of oral flora. We describe a previously un-reported case of Ludwig's angina associated with an unusual fungus, Candida Krusei. Case Description: 35-year-old, fit and healthy, non-smoking male patient presented with ludwig's angina and sepsis, previously diagnosed with parotitis following telephone consultation with his GP due to the COVID-19 pandemic. CT scan showed periapical pathology of both carious lower third molars with involvement of deep neck tissue spaces including the prevertebral space. The patient underwent multiple theatre visits for neck exploration and had prolonged hospital stay and subsequently recovered and discharged. Tissue samples grew Candida Krusei on multiple occasions. Discussion(s): This is a rare and previously unreported case of Ludwig's angina related to Candida Krusei. Literature search was carried out using MeSH terms Candida krusei, dental infection, neck infection, cervicofacial infection and Ludwig's angina using EMBASE, Medline, PubMed and Google Scholar. Candida Krusei has low disease-causing potential when compared to commonly found candida, with poor adhesive properties to oral cavity. It is not well-studied with regards to its virulence but has high resistance to azoles and other antifungal medications. Conclusion/Clinical Relevance: This report emphasises keeping an open mind when considering potential pathogens in cervico-dentofacial infections, to test tissue for fungi as well as bacteria, and to seek timely advice from microbiologists. The authors also counsel caution when carrying out telephone consultations during the ongoing COVID-19 pandemic. Copyright © 2022
