Background: Impacts of primary oncology surgical procedure can impede restoration objectives. Restoring oral function, comfort and aesthetics is a challenge due to limitations in the restorative treatment options. Methodology: Literature review on the responsibilities, role of maxillofacial prosthodontist, materails and retentive aids used for prosthesis, classification of maxillofacial prostheses, recent advancements in MFP and Workflow for the fabrication of obturator prostheses in the COVID-19 pandemic scenario. Case report on the fabrication of Holllow bulb definitive obturator during pandemic crisis. A 47 years old male patient reported for post-surgical evaluation in maxillary posterior region of oral cavity. The patient had partial maxillectomysurgical procedure of squamous cell carcinoma in the palate 5 years back. To replace the gap created, the patient was using interim obturator. He had facial asymmetry and collapse. Prosthodontic rehabilitation with one piece closed hollow bulb obturator was planned & subsequently fabricated for the patient. For our case considering the feasibility & ease of manipulation, heat activated acrylic resin was used for this particular patient for rehabilitation. The method described is easy, simple, time saving & economical. Bulb portion was hollow & made of heat cure resin, so weight was less & less chances of tissue irritation. Results: With the Covid-19 infection protocol measures taken definitive obturator was given to the maxillectomy patient to restore aesthetics, function and comfort as well. After insertion of prostheses mastication, deglutition and phonetics were improved. Breathing problems were resolved and aesthetics was improved. Conclusion: A simplified technical approach for the treatment of a patient with palatal defect of and other supportive structure has been presented in Covid-19 situation following the described infection prevention protocols. The technique presented offers a method of obtaining a detailed impression of the defect and promptly provides the patient with a light weight, easyto- use and flexible tissue- tolerant obturator.

The clinical presentation of typical lipomas is often characteristic. But the variations of lipoma based on the associated stroma poses a challenging picture with clinical diagnosis varying from benign tumors, various inflammatory and reactive lesions, salivary gland lesions, to few peripheral odontogenic lesions. Only a thorough clinical and pathological evaluation and correlation will help in arriving at a conclusive diagnosis, in understanding the behaviour, planning the treatment and predicting the prognosis of the lesion. One such case of lipoma presenting as an unassuming swelling clinically, but showing exuberant vascular component occurring on buccal mucosa is presented. A review of this variant of lipoma is discussed in comparison with the present case.

Oral exfoliative cytology is one of the easy, simple, economical and non-cumbersome diagnostic adjunct. It involves examining the exfoliated buccal cells for alterations in cellular and nuclear features. It offers the advantage of being useful in less resource setting areas. Though associated with many false results, the newer technological advancements have proven its diagnostic efficiency. Oral exfoliative cytology can readily be used as adjunct to disease diagnosis, however, it cannot replace biopsy.
