Introduction: Permanent canines are considered as the cornerstone of mouth. Canines are important for esthetics and function as they are located in the anterior segment of the mouth and help in tearing of food. An impacted tooth is that tooth that cannot or will not erupt into its normal functional occlusion due to some circumstances. Those impacted tooth are considered pathologic as they might lead to various problems like resorption of roots of adjacent teeth, cystic formation, and infection with partial eruption leading to pain and trismus. Materials & Method: All the patients (550) being treated in department of Orthodontics in Nepal Medical College from January 2017 to December 2019 were included in the study. Patients aged 13-30 years were included in the study. Clinical examinations and panoramic radiographs of patients were taken. Anterior occlusal view was done in those patients having canine impaction to determine the patterns of impaction. Data was processed in SPSS version 16.0. Result: Among 550 orthodontic patients, 31 patients were found to have canine impaction. Among them 18 (58.1%) were females and 13 (41.9%) were males. The overall prevalence of canine impaction was found to be 5.6%. Various dental anomalies were observed in the participants’ radiographs, the most common being the retained deciduous teeth (54.8%) followed by dilacerations of adjacent teeth (51.6%). Peg shaped lateral incisors and root resorption of adjacent tooth were almost equal (22.6%) with least being the odontomas and other impacted teeth. Conclusion: The prevalence of canine impaction in tertiary care dental hospital in Kathmandu was found to be 5.6%. Patients with impacted canines also had other dental anomalies. Knowing the prevalence of impacted canines, will encourage the community to be aware about canine impaction and educate the population about the clinical implications and the importance of performing preventive and interceptive procedures.

Objective: To access the awareness of dental practitioners of Nepal towards COVID-19 transmission through aerosols.Materials and Methods: The study involved 384 dentists from all over Nepal and was conducted for a period of three months. A self-reported online questionnaire was developed using Google forms and the link was shared. It emphasized the awareness related to the aerosol and ventilation system in their daily practices was prepared. The data were analysed in Statistical Package for Social Sciences version 20.0 software. Results: Majority of participants were female 52.9% (n = 203) and within the age groups of <30 years 57% (n = 219). Participants from Bagmati Province were 60.4% (n = 232), with least from Sudurpaschim Province 0.5% (n = 2). 60% of participants provided only emergency services during the COVID-19 pandemic and few (7%) provided consultations via telephone. The current ventilation system used was a well-ventilated room with open windows 65.4% (n = 251). However, 52.8% (n = 203) preferred specialized operatory incorporating high efficiency particulate air (HEPA) filters and ultraviolet (UV) light. More than 60% of respondents were unaware of the particle size of the aerosol.Conclusions: The obtained results signify the need for the proper ventilation system with appropriate air filtration systems in dental clinical setups.

Background: In elderly, poor oral health in the form of tooth loss, dental caries, periodontal disease and oral cancer affects physical and psychological aspect of life. Health is not only absence of disease but also psychological and social well-being. Thus, the assessment of disease by clinical examination as well as measurement of psychosocial impacts associated with disease are equally important. Aim: To find the association between periodontal status and oral health-related quality of life among elderly attending Kantipur Dental College. Materials and Methods: A cross-sectional study was carried out among 184 elderly patients attending Kantipur Dental College by convenient sampling method. Oral health-related quality of life was assessed by GOHAI. Periodontal status was assessed by using CPI modified and Loss of attachment. Data was analysed with SPSS version 20. Results: Among 184 total participants (74 men, 110 women), the mean GOHAI score was 46.59+8.70. Of the total, 13% had high GOHAI score whereas 27% had moderate and 60% had low GOHAI score. Periodontal status of elderly population was found to be significantly associated with oral health-related quality of life (p<0.05). Conclusion: The findings of this study suggest a need to improve oral health care and knowledge for elderly group through preventive and curative public health measures.

Introduction: According to World Health Organization, oral health means the retention throughout life of a functional, aesthetic and natural dentition of not less than 20 teeth and not requiring a prosthesis. The major reasons for tooth loss are dental caries and periodontal disease. Proper understanding of reasons for tooth loss helps to improve oral health. Objective: To identify the reasons and patterns of permanent teeth loss among patients attending Kantipur Dental College. Methods: A cross-sectional study was carried out among 403 patients aged 18 years and above attending Kantipur Dental College, Kathmandu by convenience sampling method. Data was collected through structured questionnaire and clinical examination and was analysed using SPSS version 20. Results: A total of 403 patients were examined of which 38% had tooth loss. Mean number of tooth loss was 2.99+3.44. Statistically significant difference was found in mean tooth loss between age groups and levels of education (P value < 0.001). Dental caries was the most common reason of tooth loss followed by periodontal disease. Most common reason for not saving the tooth was "tooth cannot be saved" (65.1%). Mandibular molars accounted for majority of tooth loss followed by maxillary molars. Conclusion: The results of the present study show that dental caries was the major cause of tooth loss irrespective of the age group. It points out the need to carry out oral health awareness and other preventive programs both at school and community levels.
