Introduction: COVID-19 disease is caused by SARS-CoV-2 virus and it was declared pandemic by World Health Organization (WHO) on March 11,2020. The coronavirus infection has an affinity for ACE2 receptors and by attaching to them, the virus enters the host cells. Along with many body organs like lungs, kidney, liver, upper respiratory tract, nervous system, skeletal muscles, ACE2 concentration is also found in abundance in epithelial cells of tongue and salivary glands. Materials and Methods: Recent studies, researches, documents and case reports published in the world medical literature in the year 2020-2021 were searched and documented in our study. The search engines used were PUBMED, google scholar, WEB OF SCIENCE etc. Results: Dysgeusia, xerostomia, sore throat, aphthous and herpetiform ulcers, candidiasis, enanthema, Kawasaki like lesions were the most common among various oral manifestations. Others includes plaque like changes, gingival inflammation, necrotizing gingivitis, erythema -multiforme, angina-bullosa like lesions, Melkersson-Rosenthal Syndrome, Oral mucormycosis etc.The sites of infection mainly include tongue, gingiva, hard and soft palate, buccal and labial mucosa etc. Conclusion: The etiopathogenesis of such lesions cannot be directly corelated with COVID-19 and factors such as stress, immunosuppression, co-infections, secondary lesions, opportunistic infections, systemic diseases, poor oral hygiene etc. must be considered. Management of stress is an important factor. In this review article various oral lesions are discussed in COVID-19 infection states in detail. The importance of earliest diagnosis of oral lesions is to be kept in mind to prevent further complications.

Lipoma is one of the benign soft-tissue tumors in the adipose tissue. Oral lipomas comprise 1%–5% of benign oral tumors. They are slow-growing, soft, asymptomatic, solitary tumors. In this case report, a 45-year-old female patient having swelling on the upper right arch for 2 months has been reported. Clinically, the right upper second premolar and first molar were grossly carious, with diffuse swelling on the adjacent vestibule. A provisional diagnosis of the periapical abscess was rendered. Radiological evaluation and routine blood tests were performed. After the tissue was obtained, following teeth extraction and socket curettage, it was sent for histopathological evaluation, and findings suggested intraoral intraosseous lipoma. Clinically, they are asymptomatic, and therefore, if it was not curetted and histopathologic evaluation not done, and only thought to be just a swelling or a periapical abscess, proper treatment could not have been established. This paper will surely bring out the importance of histopathology in routine dentistry and the role of histopathological evaluation of periapical soft tissues.

During the second wave of coronavirus disease, or COVID-19, infection due to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus in the year 2021 around the globe, there is a surge in the number of cases of mucormycosis or "Black Fungus" that is directly/indirectly associated with COVID-19.In this review article, mucormycosis of the orofacial region has gained importance from the maximum published literature (45 articles) from various databases like PubMed, Google Scholar, Scopus, Web of Science, and Embase.Rhino-orbital cerebral mucormycosis (ROCM) is a fatal condition associated with COVID-19 among categories of mucormycosis such as pulmonary, oral, gastrointestinal, cutaneous, and disseminated. ROCM targets the maxillary sinus, also involving teeth of the maxilla, orbits, and ethmoidal sinus. These are of particular interest to dentists and oral pathologists for proper diagnosis and identification. Co-morbid conditions, especially diabetes mellitus type II, have to be monitored carefully in COVID-19 patients as they have a higher risk of developing mucormycosis. In this review article, various presentations of COVID-19linked mucormycosis are mentioned having particular emphasis on pathogenesis, signs and symptoms, clinical presentation, various diagnostic modalities including histopathology, radiology like CT and MRI, serology, tissue culture, various laboratory investigations, treatment protocols, management with prognosis, and so on. Any suspected case of mucormycosis needs quick detection and treatment since it progresses quickly due to the destructive course of infection.Long-term follow-up along with proper care is a must to detect any kind of recurrence.
