Objective: To explore student’s perceptions regarding impact of kinesics (facial expressions, gestures, head movements and postures) on undergraduate medical education. Methods: A qualitative exploratory online survey was conducted from July-Sept 2020 among purposively chosen final year BDS students (n=150) of three dental colleges of Islamabad during COVID-19 lockdown phase. Semi-structured survey questions were validated and piloted before execution. Thematic analysis was performed, and consensus was built among all authors regarding findings, hence ensuring analytical triangulation. Results: Response rate was 46% (69/150). Twenty sub-themes emerged under three domains of kinesics. Participants told that ‘neutral expressions’ frequently used by teachers create ‘boring learning environment’ and ‘hesitation among students to ask questions.’ A smile of teacher imparts ‘new degree of interest in the subject’ and gives ‘freedom of expression’ to the students. On contrary, anger ‘demotivate’ students, instills ‘fear among them’, make them anxious therefore, they are ‘unable to understand lectures’ which ultimately leads to ‘loss interest in the subject’. Use of gestures by teachers creates ‘enjoyable teaching-learning process’ but movements such as clearing throat or shaky legs produce ‘constant split-second interruption’. Moreover, standing posture of teachers bring ‘interest and alertness among students’. Conclusion: Nonverbal communication can have positive or negative impact on undergraduate medical education. Therefore, teachers may start lecture with a smile and anger should be avoided to produce friendly and healthy learning environment. Faculty training is required for the effective use of nonverbal communication strategies to create an optimal learning environment for the students. doi: https://doi.org/10.12669/pjms.37.7.4180 How to cite this:Aziz A, Farhan F, Hassan F, Qaiser A.

Objective: To study the clinocopathological factors and presence of Human Pappiloma Virus in ameloblastoma by immnohistochemistry. Methods: It was a cross sectional study on 50 surgical specimens of ameloblastoma, completed in six months. These were selected and processed for initial screening by H&E and then by immunohistochemistry (IHC) for detection of Human Papilloma Virus (HPV). The questionnaire was designed to study the clinicopathological factors associated in these patients. Sections of 4µm were cut, placed on special positive charged glass slides in the Department of Pathology, King Edward Medical University. It was then examined by the histopathologists for grading and scoring of these lesions. Chi Square test was used to assess the differences found in types of ameloblastomas. The p-value was smaller than 0.05 (p < 0.05). Results: The mean age of the patients (12-80 years old) was 38.6±15.1 years, with male-female ratio 2.84: 1. HPV was positive in 9 (18%), whereas negative in of 41 (82%) patients. Among the positive, reactive HPV with score-1 was 8 and score-2 was 1. According to histological variant, follicular was present in 78%, Plexiform pattern in 8%, Conventional and Desmoplastic variants in one patient each; and Cystic and Acanthomatous were seen in two and three patients respectively. The mandible was involved in 39 patients, maxilla and right maxilla involved in 4 patients each, right retromolar, cheek and angle of mandible was seen in one patient each. About 16% patients had anterior, 66% had posterior and 18% had both anterior and posterior regions involved. Among the HPV positive reactive statistically, no significant difference was found with smoking, Paan and exposure to pesticides, factory or mine (p-value > 0.05). Among HPV positive reactive patients, eight had ameloblastoma whereas, 1 had ameloblastomic fibroma. There was no statistical significance of type, location and region of tumor in HPV positivity. Conclusion: Mandible and posterior region was more commonly involved. Follicular pattern was most common. There was no effect of exposure to pesticides, factory or mine, smoke and human papilloma virus in the etiology of ameloblastoma because only 18% of patients showed the association of HPV16 doi: https://doi.org/10.12669/pjms.35.6.909 How to cite this:Ali M, Bukhari MH, Hassan F, Illyas M.
