OBJECTIVES:  To find the association of extraversion personality traits with oral parafunctional habits. METHODOLOGY: A Cross-sectional descriptive study was conducted on 200 individuals in the College of Dentistry, Sharif Medical and Dental College, Lahore, over 5 months from July to November 2021. Data was collected using a pre-validated medical questionnaire and a ten-item personality inventory scale (TIPI). The sampling technique used was Convenience sampling. A sample size of 200 was calculated with the help of WHO sample size determination software. RESULTS: There was a statistically significant difference in the scores of extraversion personality traits across the oral parafunctional habit group of nail-biting (p= 0.007). In contrast, that for tooth grinding (0.114), tooth clenching (0.076), biting hard objects (0.74) and chewing gum (p= 0.659) was non-significant. The highest mean rank score for the personality trait of extraversion was found in individuals who strongly agreed to have a habit of nail-biting (129.23), tooth grinding (153.63), and tooth clenching (142.61) and biting hard objects (12.07). The highest mean rank score for the parafunctional habit of chewing gum (107.28) was found in individuals who strongly disagreed with having the habit. CONCLUSION: The highest mean rank score for the personality trait of extraversion was found in individuals who strongly agreed to have a habit of nail-biting, tooth grinding, tooth clenching and biting hard objects. The highest mean rank score for the parafunctional habit of chewing gum was found in individuals who strongly disagreed with having the habit.

To evaluate dentists' knowledge, attitude, and practice of cross infection control protocol. The questionnaire proforma was based on 15 questions was used to check the knowledge, attitude, and practice of the standard infection control protocols among the 3rd and 4th-year students of BDS, house officers and demonstrators of College of Dentistry, Sharif Medical and Dental College, Lahore, who were active in dental health provision in a clinical setting. A total of 200 participants were enrolled in the study after convenient sampling. We found that despite good knowledge of safety protocols, implementation of these standards is lacking. Non-compliance in following standard infection control protocols is a big challenge and can increase the risk of cross-infection. Keywords: cross-infection, dental practitioners, sterilization.
