Purpose: Xerostomia is a serious concern with many ramifications observed in the oral cavity. Dentists can recognize the features of xerostomia early and relieve the discomfort of the patient. The relationship between xerostomia and its risk factors has been established but the risk factors have been considered independently or with no distinction among the causative components of xerostomia. Studies relating to xerostomia and edentulism with relation to risk factors and symptoms are not very many. Methods: A cross-sectional study was conducted in partially and completely edentulous patients. Questionnaires were completed by 234 participants. The questionnaire recorded the socio-demographic information, medical history, oral hygiene habits, and symptoms of xerostomia. Clinical examination was done to record the missing teeth. All the data were collated into an excel sheet and statistically analyzed. Results: The mean age of the participants was 54.6 years. Of the 234 participants, 68 (29.05%) had xerostomia. The older age group (>50 years) showed a higher prevalence of xerostomia than the younger age group (<50 years), past smokers complained more of xerostomia than the current smokers and as the number of medications increased xerostomia increased, but none of them were statistically significant. Conclusion: The prevalence of xerostomia in partially and completely edentulous patients was 29.05%. None of the variables of risk factors were associated with xerostomia. Dry lips and dry throat were strongly associated with xerostomia.

Background: Due to COVID-19 pandemic globally, regular schooling and teaching were disrupted and e-learning has become the major mode of teaching and learning from the age of childhood to professional colleges. After the first and second waves of the COVID-19 pandemic, the present survey was undertaken to assess the knowledge, attitude, and perception of dental undergraduates of Mysore city, India.

The study was conducted in the month of September and October 2020. There were about 184 students present in both 3rd and 4th year BDS. The questionnaire was sent to all the students through SurveyMonkey. Out of 184 students, 134 students responded for the questionnaire and the response rate would be around 72.82%. Validity and reliability were assessed before finalizing the questionnaire. Results: Almost 90% of the students had a computer and Internet facilities and they have computer and Internet facilities. Two-thirds of the students preferred blended learning, i.e., a combination of e-learning and a traditional classroom environment, and that the assignments could be finished better in a traditional method. Regarding satisfaction, 80% of the students expressed dissatisfaction toward online learning. Conclusion: Although the dental students had computer and Internet facilities, they had negative perceptions and attitudes toward online learning. Almost all students favored the traditional method of learning.
