RESUMO
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.
RESUMO
Background: In the COVID-19 age, attempts are being made to raise student awareness and improve best practices to contain the outbreak. Methodology: The target population was interns and 3rdyear undergraduate students from JSS Dental College and Hospital, Mysuru. COVID-19 knowledge, awareness and attitude of the students and interns and the preparedness to tackle the current COVID 19 pandemic were assessed. Results: 120 respondents responded via a contented validated self-administered questionnaire with regard to knowledge, attitude and practices and preparedness to address the COVID 19 pandemic by undergraduates and interns. The student participants irrespective of their years into practice were aware of the guidelines being issued by Health care authorities and to address the COVID 19 pandemic. Among the respondents, 57.5% were 3rd year dental students and 42.5% were interns. Regarding knowledge about COVID infection, 42.9% (3rd year students) and 57.1% of the interns were aware of the recent developments, 34.1% of the III year students were aware of the safe distance to be maintained between patients, 42.4% of the students and 57.6% of interns were aware of the authority to be contacted with suspected COVID 19 infections. The participants were also aware of the vaccine trial which was conducted. Most of the respondents (64.3% of the students and 78.6% of the interns) were aware of fumigation in clinical or high-contact areas on a daily basis and biweekly in nonclinical areas. Conclusions: The results suggest a strong need to encourage the current training program among students in health care-related fields.
