(Nepal Medical Association, 2021) Bhattarai, Bhagabat; Gupta, Sujaya; Dahal, Sirjana; Roy, Deepak Kumar; Pant, Saroj; Karki, Rachana; Thakuri, Tanu
Abstract: Introduction: The aetiological factors of dental fear include negative information, witnessing or having a bad experience, and negative conditions related to periodontal treatment. Modified Dental Anxiety Scale Nepali version, is one of the tools used in epidemiological studies to measure dental anxiety in adults. The objective was to find out the prevalence of anxiety among dental patients visiting for periodontal therapy in a tertiary care hospital. Methods: This descriptive cross-sectional study was conducted among patients visiting for periodontal therapy from November 2020 to January 2021 at a tertiary care dental hospital. Ethical clearance from Institutional Review Committee (Reference no. 0311202001) was taken before the study. Convenient sampling was done. A standard questionnaire for dental anxiety was used for data collection after receiving informed consent from the participants. Data were entered and analyzed in Microsoft Excel Sheet. Descriptive data are presented as means, standard deviations, frequencies, and percentages. Results: Among a total of 311 participants visiting for periodontal therapy, 297 (95.49%) (92.57-97.42 at 95% Confidence Interval) were having anxiety. Among total patients, 113 (36.33%) were fairly anxious, 111 (35.69%) were slightly anxious, 62 (19.94%) very anxious and 11 (3.54%) were extremely anxious. Majority of males 54 (17.36%) were slightly anxious while most females 67 (21.54%) were fairly anxious. Mean Modified Dental Anxiety Scale-Nepali score of all the participants was 11.59±3.808. Extreme dental anxiety was observed in 11 (3.54%) participants 7 (2.25%) females; 4 (1.29%) males. Conclusions: The prevalence of anxiety among patients visiting for periodontal therapy in this study was found to be higher compared to other studies done in similar settings.

(Nepal Health Research Council, 2025) Niroula, Deepa; Dahal, Sirjana; Poudel, Kalpana; Singh, Ashutosh Kumar; K.C, Krishna
Background: An important anatomical factor in injuries to the inferior alveolar nerve is the spatial relationship between the mandibular canal and the corresponding third molars. This study was designed to classify the anatomic three-dimensional relationship between mandibular third molars and the mandibular canal on cone-beam computed tomography mages. Methods: A cross-sectional study was conducted by using CBCT images of 100 individuals visiting the Dental Outpatient Department of X hospital from Jan 2022 – Oct 2022. The images were used to classify the threedimensional relationship between the mandibular canal relative to the roots of the mandibular third molar according to Liqun Gu et al 2018 classification. In this classification, four anatomical positions were considered: buccal, lingual, apical and inter-radicular. The second factor considered was the contact and non-contact relationship between the inferior alveolar nerve canal and the mandibular nerve. The data was analyzed via SPSS version 20. Chi square test was performed to determine the contact relationship of the mandibular third molar root with the mandibular canal. Results: Most of the mandibular canals observed via CBCT (45.0%) were located on the buccal side of the mandibular third molar followed by the apical side (26.0%), between the roots (23.0%) and very few (6.0%) on the lingual side. A significant association was found between the position of the mandibular third molar and the mandibular canal (p<0.001) when the position was lingual and interradicular. Conclusions: The findings of this study revealed that the majority of mandibular third molars were located on the buccal side. There was a significant relationship between the position of the mandibular third molar and the mandibular canal. Keywords: Cone-beam computed tomography; impaction; mandibular canal; third molar.

(Institute of Medicine, 2022) Guragain, Manjeev; Dahal, Sirjana; Joshi, Kalit R; Rathi, Ankita; Dahal, Samarika; Poudel, Samikshya S; Pantha, Sandesh; Bhochhibhoya, Amar
ABSTRACT Introduction: Most of the dental research has focused on dentist’s perceptions of patients based on their demographic profiles, while little is known about patient’s perceptions of their dentists. Further, there is a lack of data regarding patient preferences in selecting prosthodontists based on gender and age in Nepal. This study aims to investigate the influence of various demographic factors on patient preferences in selecting their prosthodontist. Methods: A sample of 358 patients presenting at the Department of Prosthodontics, Tribhuvan University Teaching Hospital, Institute of Medicine for replacement of missing teeth took part in this questionnaire-based study. The questionnaire was designed to assess the influence of sex and age of the prosthodontist on the decision to select a prosthodontist. Statistical analysis was performed by SPSS version 16. Results: Majority (258, 72.1%) preferred treatment by a prosthodontist of age <44 years. There was a significant association seen between participants’ age, sex, and educational status and age preference for prosthodontists. Also, their sex, educational status, and prosthodontist among family and friends were significantly associated with prosthodontist’s sex preference. Conclusion: There was preference for younger prosthodontists by the study participants but they had no gender preference for having their treatment done. Keywords: Age, gender, preference, prosthodontist, treatment

(Nepal Medical Association, 2025) Ghimire, Saru; Ghimire, Sagar; Dahal, Samarika; Dahal, Sirjana; Paudel, Neetika; Paudel, Prayash
Abstract 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.
