Publication Classification of Impacted Third Molars on Conebeam Computed Tomography Images(Nepal Health Research Council, 2025) Niroula, Deepa; Dahal, Sirjana; Poudel, Kalpana; Singh, Ashutosh Kumar; K.C, KrishnaBackground: 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.Publication Comparison of Asthma Control Test and GINA based assessment in Nepalese population: A cross-sectional study(Nepalese Respiratory Society, 2024) Dhungana, Ashesh; Lamichhane, Buddhi Sagar; Shrestha, Prajowl; Shrestha, Deepa Kumari; Niroula, DeepaAbstract: Introduction: Asthma has a high age adjusted mortality in low- and middle-income countries like Nepal, which is preventable. Asthma control test (ACT) and GINA based assessment are the two most used tools to monitor effectiveness of the treatment. Utility these tools have not been evaluated in patients with asthma in Nepal. Objective: This study aims to compare the agreement between ACT and GINA assessment tools in Nepalese population. Methods: In a cross-sectional observational study, patients aged more than 18 years diagnosed as asthma at least three months prior were included. Active smokers and those with concomitant other respiratory disorder were excluded. ACT translated to native Nepali language was self-administered by the patient. GINA assessment of asthma control was recorded by the physician. Patients were classified as having well controlled, partially controlled and poorly controlled asthma by using both the tools. Spearman’s correlation coefficient was used to evaluate the agreement between the ACT and GINA based classification. Results: A total of 56 patients were included into the study. The mean age was 39 ± 12 years and the median duration of symptoms was 39.5 (IQR = 25.5-53.5) months. Using the GINA recommended asthma control tool, the number of patients with well controlled, partially controlled and poorly controlled asthma were 21 (38%), 24 (43%) and 11 (20%) respectively. Using the ACT scores, 35 (63%), 11 (20%) and 10 (18%) patients had well, partially, and poorly controlled asthma respectively. Both ACT and GINA score had a good agreement in classifying poorly controlled asthma. ACT and GINA scores had a weak positive yet statistically significant correlation (Spearman’s rho= 0.752, p= 0.019). Conclusions: ACT and GINA based assessment tools have good agreement to identify poorly controlled asthma in patients with asthma in Nepal.Publication Periodontal Lesions among Maxillary Sinus Mucosal Thickening Visiting the Department of Oral Medicine and Radiology of a Tertiary Care Centre(Nepal Medical Association, 2024) Bali, Harleen; Neupane, Manisha; Mahanta, Swagat Kumar; Niroula, Deepa; Upadhyaya, Chandan; Kafle, DashrathAbstract Introduction: Maxillary sinus due to its proximity to posterior maxillary teeth could be affected by their pathology. Since cone beam computed tomography is the go-to for 3-D imaging in dental set-up. This study aimed to find out the prevalence of periodontal lesions among maxillary sinus mucosal thickening visiting the Department of Oral Medicine and Radiology of a tertiary care centre. Methods: This descriptive cross-sectional study was conducted in the Department of Oral Medicine and Radiology of a tertiary care centre from 01 February 2021 to 30 June 2021 after obtaining ethical approval from the Institutional Review Committee. The medical records from 01 January 2019 to 31 December 2019 were retrieved. The identification of maxillary sinus mucosal thickening of more than 3 mm, in cone beam computed tomography images, was registered separately for the right and left sinuses of each patient. The presence of periodontal lesions of posterior teeth was recorded. A convenience sampling method was used. The point estimate was calculated at a 95% Confidence Interval. Results: Among 195 maxillary sinus mucosal thickening, periodontal lesions were found in 74 (37.95%) (31.14-44.76, 95% Confidence Interval) maxillary sinuses of 46 patients. The mean age was 53.67±12.72 years and 30 (65.21%) were males. Conclusions: The prevalence of periodontal lesions among maxillary sinus mucosal thickening in CBCT images was similar to other studies done in similar settings.
