The lungs are the organs of respiration which are situated on either side of the heart and other mediastinal contents in its pleural cavity. A fresh lung is spongy, can float in water and crepitates when handled. Lungs are important with respect to its blood circulation. The lungs are divided by fissures into lobes which facilitate movements of lobes in relation to one another. The hilum of each lung is its gateway. In the present study, we aim to assess the morphological variations of human cadaveric lungs at Chitwan Medical College (CMC). An observational study was conducted at dissection hall of anatomy department at Chitwan Medical College from September 2019 to October 2020 after taking ethical approval form Institutional Review Committee of CMC. All the intact 70 lungs present in the department were studied. Photographs of the intact lungs were taken from different surface. The lungs were porus, highly elastic and spongy in texture. On keeping lungs to water tank it got floated. We found 34(80.96%) of the studied specimen of right side had horizontal fissure present in it. The remaining 8 (19.04%) specimens did not have horizontal fissures, while 3 (5.88%) specimens had incomplete fissures. The oblique fissure was not present in 2 (2.38%) of the study specimens. The left side of the study specimen has a variance of 1(4.16%). When the hilum right lung was examined, 40 (95.23%) of the structure had the usual organization pattern. In the left lung, the usual pattern of organization was 21(75%). The differences are thought to be present in the lung’s fissure and hilum. The current study’s findings are therapeutically important. The findings could prove beneficial to cardiovascular and thoracic surgeons.

Introduction: The main blood supply for arm is provided by the brachial artery. It shows variation in branching and termination patterns in some individuals. Variation in brachial artery may cause difficulties during various clinical and surgical procedures. The present study aims to find out the prevalence of higher termination of brachial artery in cadavers in the department of anatomy of a medical college. Methods: A descriptive cross-sectional study was carried out from 10th January 2020 to 20th April 2021 after the ethical approval was taken from the Institutional Review Committee of Nobel Medical College (reference number: IRC-NMCTH 280/2020). The study was done in 58 upper limbs of 29 properly embalmed cadavers. Convenient sampling was done. They were carefully dissected. The level of termination of brachial artery was noted. The length of the brachial artery and the distance between its termination and the intercondylar line of humerus was recorded. Results: Higher termination of brachial artery was observed in 3 (5.17%) extremities; one (1.72%) at middle third of arm and two (3.45%) at lower third of arm. In 52 (89.66%) extremities, the site of termination was at the level of neck of radius. The brachial artery terminated a few centimeters below its usual site at the level of upper part of shaft of the radius in 3 (5.17%) extremities. Conclusions: The prevalence of higher termination of brachial artery in cadavers is slightly lower than the studies performed in similar settings. It is not an uncommon finding. It may have impact on clinical and surgical procedures.

Introduction: Additional anatomic features present on teeth are called non-metric dental traits. Carabelli’s cusp and shovelling are such traits which are mostly evaluated for identification of ethnicity. The present study aims to determine the prevalence of Carabelli’s cusp and shovelling among Indo-Nepalese and Tibeto-Nepalese ethnic group. Methods: A descriptive cross-sectional study was conducted in a tertiary hospital from March 22 to June 22 2019 after obtaining ethical approval from the institutional review committee. The study was conducted among 274 patients and convenient sampling method was applied. Data were analyzed by the help of Statistical Package for Social Sciences version 21. Results: Among 274 cases, 153 (55.84%) cases were Indo-Nepalese and 121 (44.16%) were TibetoNepalese. Carabelli’s cusp (16/26) was noticed in 87 (56.86%) of Indo-Nepalese and 45 (37.19%) of Tibeto-Nepalese. Shovelling (11, 12, 21, 22) was present in 47 (30.71%) Indo-Nepalese and 79 (65.28%) of Tibeto-Nepalese. Further, Carabelli’s cusp (16/26) was found in 77 (53.10%) females and 55 (55.12%) males. Shovelling was present in 75 (51.72%) females and 51 (39.53%) males. Bilateralism with respect to Carabelli’s cusp was present in 82 (62.2%) cases. Presence of bilateral shovelling on upper central incisors and lateral central incisors were among 117 (94.35%) and 56 (91.80%) respectively. Conclusions: Carabelli’s cusps are frequently found in Indo-Nepalese ethnic group and shovelling of teeth most commonly present in Tibeto-Nepalese population. Further, bilaterism for shovelling of teeth is more common than bilaterism for cusp of Carabelli.

ABSTRACTBackground: Impression making is one of the critical factors in determining success or failure of complete denture therapy. The precise reproduction of edentulous foundation is essential for retention, stability, and support of the removable prosthesis. Evidence suggests that there is variability in materials and techniques regarding impressions making for complete dentures. There is little published information on studies conducted among Nepalese Prosthodontists. The purpose of this study was to evaluate current materials andmethods for impressions for complete denture prosthodontics in Nepal. Materials & Methods: A questionnaire based survey was conducted among Nepalese Prosthodontists. Ethical approval for the beginning of the study was obtained via Institutional Review Committee, Nepal Medical College. A self-administered anonymous questionnaire was distributed to the participants. Data were analyzed by using frequency distribution.Results: Majority of responses indicated use of irreversible hydrocolloid in stock metal tray for making the preliminary impression. The selective pressure was the predominantly used impression philosophy (78.3%). The most common material for the fabrication of custom trays was autopolymerizing acrylic resin (96.7%). All respondents border molded the custom tray prior to making the final impression. The final impression materials used were zinc oxide eugenol impression paste (73.3%), polyvinylsiloxane (11.7%), polyether (11.7%) and polysulphide (3.3%). Conclusion: Although there is variability in impression materials andtechniques used by Prosthodontists in Nepal for the fabrication of complete dentures, the results showed interesting trends. Most practitioners followed the traditional techniques of complete denture impression procedures.Keywords: complete denture; custom tray; edentulism; impression.

Introduction: Racial variation, genetic inheritance and various other factors can affect the jaw size and ultimately the tooth size and number. Studies for agenesis of mandibular third molars (M3s) have been carried out in various populations but data relating to these are not evident from most of the parts of Nepal. Hence, the objective of the present study is to determine the prevalence of agenesis among the population of patients visiting the Department of Oral Medicine and Radiology of this institute. The study also sought the odds of agenesis of M3 in one side when there was missing M3 on the other side of the mandible. Methods: This study was conducted after the approval from Institutional Review Committee of BPKIHS. Two hundred and eighty four patients (568 sites of M3, bilaterally), visiting the Department of Oral Medicine and Radiology were studied with Panoramic Radiograph to assess for agenesis of mandibular third molars, bilaterally. Percentage of agenesis was calculated and chi square test was applied where relevant. Odds ratio was also calculated. Results: Agenesis was seen in 28.7% of the participants. The Odds of M3 being missing on one side with concurrent missing M3 on the other side was 40.27 (Confidence Interval 19.34 to 83.87). Conclusions: Agenesis was highly prevalent in this study group. The likelihood of M3 being absent on one side, when there was concurrent missing M3 on the other side of mandible was also high.
