Publication Mean Mesiodistal Width of Canine in Patients Visiting a Tertiary Care Centre: A Descriptive Cross-sectional Study(Nepal Medical Association, 2022) Baral, Radha; Dahal, Samarika; Gupta, Sanjay PrasadAbstract Introduction: The measurement of the teeth is one of the most reliable methods of identification. The teeth represent the most durable, resilient, and chemically stable part of the skeleton. The comparison of tooth dimensions is one of the tools of sex determination. Canines, in particular, are found to have the greatest degree of sexual dimorphism. The aim of the study was to determine the mean mesiodistal width of canines in patients visiting a tertiary care centre. Methods: This descriptive cross-sectional study was done among patients visiting a tertiary care centre from 25 August 2021 to 28 December 2021. The ethical approval was taken from the Institutional Review Committee [Reference number: 61 (6-11)E2 078/079]. The maximum mesiodistal width of the permanent maxillary canine was measured by a digital vernier caliper. The formula given by Garn and Len was used to calculate sexual dimorphism. Convenience sampling was used. Point estimate and 95% Confidence Interval were calculated. Results: Among 104 maxillary casts studied, the mean mesiodistal width of the maxillary canine was 7.85±0.45 mm (7.76-7.93, 95% Confidence Interval). The mean mesiodistal width of the right maxillary canine in males and females were 7.90±0.48 mm and 7.83±0.45 mm respectively and that of the left maxillary canines in males and females were 7.92±0.44 mm and 7.75±0.45 mm respectively. The sexual dimorphism in the right and left maxillary canine was seen in 10 (0.96%) and 22 (2.12%) respectively. Conclusions: The mean mesiodistal width of the maxillary canine was similar to other studies done in similar settings.Publication Prevalence of Dentinal Hypersensitivity among Dental Patients Visiting Tertiary Care Center: An Observational Study(Nepal Medical Association, 2025) Ghimire, Saru; Ghimire, Sagar; Dahal, Samarika; Dahal, Sirjana; Paudel, Neetika; Paudel, PrayashAbstract Introduction: Dentinal hypersensitivity is a widespread condition characterized by a brief, sharp pain arising from exposed dentin in response to external stimuli, which cannot be linked to any other dental conditions. This study aimed to estimate the prevalence of dentinal hypersensitivity among patients attending a tertiary health care center. Methods: A observational cross-section study was conducted, involving 376 patients aged 10-70 years who visited a tertiary care center. Convenience sampling was employed to select participants, and the prevalence of dentinal hypersensitivity was assessed through a questionnaire. Data were collected from the Department of Oral Medicine and Radiology after obtaining ethical approval Institutional Review Committee (Reference number: 385 (6-11) E2 079/80). The analysis was performed using Microsoft Excel, and descriptive statistics were reported . Results: There were 376 patients in the study and the prevlence of dentin hypersensitivity wasa 236 (62.77%; CI 95%: 57.66%-67.67%). Among those diagnosed, 138 (73.02%) were male, and 98 (52.41%) were female. The age-specific prevalence was found to be 30 (50.85%) in patients aged 10-19 years, 73 (63.48%) in those aged 20-29 years, 42 (53.16%) in patients aged 30-39 years, 23 (51.11%) in those aged 40-49 years. Conclusions: This study identified a high prevalence of dentin hypersensitivity among the patient population, with variations observed across different age and sex groups.Publication Self-Assessment of Oral Health Status among Adults Residing at Chautara, Sindhupalchowk, Nepal(Nepal Health Research Council, 2025) Dahal, Sirjana; Khapung, Anju; Dahal, Samarika; Poudel, PrakashBackground: Little is known about attitudes and practices regarding oral health of developing countries. This study aimed to determine the self-assessment of oral health status among adults residing at Chautara, Sindhupalchowk, Nepal. Methods: A descriptive cross-sectional study was conducted among 440 adults selected by convenience sampling method. Interview using WHO oral health questionnaire for adults 2013 was taken after receiving informed consent. Data were entered in Microsoft Excel Sheet and analysed in SPSS version 24. Mean, standard deviation, frequency and percentage were calculated. Results: Majority had positive assessment regarding their teeth (366, 83.18%) and gums (384, 87.27%). Many (417, 94.77%) cleaned their teeth ?one times a day. Majority used toothbrush (434, 98.64%) and paste (411, 93.41%) for cleaning their teeth. Some, (184, 41.82%) visited a dentist at least once in their lifetime and the main reason was pain or trouble in teeth/gums/mouth (94, 51.09%). Very often, they faced problems chewing (31, 7.0%) and biting (27, 6.1%) foods. They mostly consumed tea with sugar (132, 30.0%) and biscuits, cakes and cream cakes (59, 13.4%) several times a day. Most of them smoked cigarettes every day (93, 21.1%), followed by tobacco chewing (67, 15.2%). In the past 30 days, 179 (40.7%) drank one or more drinks of alcohol. Conclusions: The study findings showed that most of the adult residents of Chautara, had positive self-assessment of their oral health status. However, they faced many oral health problems which may be due to their unhealthy lifestyle suggesting need for oral health awareness programs. Keywords: Adults; oral health; self-assessment.Publication Type I Lip Patterns among Medical Students of a Medical College(Nepal Medical Association, 2023) Shrestha, Kabir; Dahal, Samarika; Baral, Radha; Neupane, AbishikhaAbstract Introduction: Identity and identification have long been a source of interest and concern in forensic dentistry, whether in the context of a criminal investigation or the identification of a deceased person. Lip print has demonstrated a high level of potential as one of the best options, as well as its usage as supporting evidence. The aim of this study was to find out the prevalence of Type I lip patterns among medical students of a medical college. Methods: This descriptive cross-sectional study was done among medical students of a medical college from 30 December 2021 to 30 February 2022 after obtaining ethical approval from the Institutional Review Committee. The lipstick was applied in a thin layer uniformly, and the impression was taken with the help of the cellophane tape. The specimens were analyzed and classified based on Tsuzuki and Tsuchihashi's classification. A convenience sampling method was used. The point estimate was calculated at a 95% Confidence Interval. Results: Among 120 medical students, the prevalence of type I lip pattern was 48 (40%) (31.23-48.77, 95% Confidence Interval). Among them, 26 (54.17%) were males and 22 (45.83%) were females. Conclusions: The prevalence of Type I lip pattern among medical students was higher than in other studies done in similar settings.
