Publication Comparative Study to Determine the efficacy of Zinc Oxide Eugenol and Alveogyl in Treatment of Dry Socket(Kathmandu University, 2017) Chaurasia, NK; Upadhyaya, C; Dixit, SABSTRACT Background Dry socket is one of the most common complications following permanent tooth extraction, especially mandibular third molar. Management remains controversial and different authors have shown different results with the use of zinc oxide eugenol and AlveogylTM, some preferring AlveogylTM over zinc oxide eugenol. Objective To determine the incidence, possible risk factors and compare the effectiveness of two most commonly used agents (Zinc oxide eugenol and AlveogylTM) for management of dry socket. Method Dry socket patients were randomly divided into two groups. Various risk factors were recorded through proper history. After thorough irrigation with normal saline, zinc oxide eugenol paste mixed with cotton pellet was placed in one group whereas AlveogylTM was placed in another group. Intensity of pain was recorded on visual analogue scale of Zero to ten. Pain score was recorded at the time of diagnosis, thirty and sixty minutes after placement of medication and on second, fifth, seventh and tenth day. The medication was changed every day until the pain subsided. The data were collected and analyzed using SPPS software (version 20). Result Incidence of dry socket was 4.70%, more common in males (59.09%). It was more common after extraction mandibular third molar. Initial and final pain relief on visual analogue scale was better with use of zinc oxide eugenol. Conclusion Zinc oxide Eugenol paste is more effective in management of dry socket for early as well as final pain relief compared to AlveogylTM. KEY WORDS Alveogyl, dry socket, visual analogue scale, zinc oxide eugenolPublication Etiology, Pattern, Treatment and Outcome of Maxillofacial Fractures at Dhulikhel Hospital(Kathmandu University, 2021) Chaurasia, NK; Upadhyaya, C; Dulal, SABSTRACT Background Maxillo-Facial region is one of the prominent parts of human body and is more vulnerable to injury when any form of trauma is encountered. Injury to this region can result in fractures and pattern of fractures often depends upon the mechanism of injury as well as direction of impact. Objective To determine the etiology, pattern, treatment, and outcome of maxillofacial fractures presenting to Dhulikhel hospital. Method The records of all the patients with maxillofacial injuries presenting to the department of oral and maxillofacial surgery of dhulikhel hospital between period of December 2012 to November 2019 were included in the study. The data regarding age, sex and etiology were recorded. The etiologies were classified as Motor vehicle accidents (MVA), interpersonal violence, fall injuries, sports related injuries, occupational hazards, gunshot injuries and animal attacks and others. Similarly, the pattern of fractures was recorded according to classification by anatomical site. The types of treatment performed was also recorded. Treatment outcome in the form of any post- operative complications were recorded. Result Out of 1366 patients with maxillofacial injuries, 378(27.7%) patients had fracture of maxillofacial region. The most common etiology was motor vehicle accidents (53.7%) followed by fall injury (31.2%). Zygomatico-maxillary complex was the most common type of fracture (27.9%). Open reduction and internal fixation were the most common form of treatment provided (85.4%) and post-operative complications were minimal (5.0%). Conclusion Motor vehicle accidents still remain the most common cause of maxillofacial fractures. Midface fractures are more common than mandible fracture. The present study provides an insight into changing etiology and pattern of maxillofacial fractures and open reduction and internal fixation remains the most favored treatment of maxillofacial fractures with minimum complications.

Objective To evaluate the incidence and pattern of mandibular impacted third molars in patients of Dhulikhel Hospital. Method A retrospective study was conducted from March 2016 to November 2016 and reviewed 581 orthopantomograms and clinical records of patients who presented to the Department of Oral and Maxillofacial Surgery. The angulation of impaction was measured using Winter’s classification and the level and position of impacted third molar was recorded using Pell and Gregory classification system. The etiology for extraction was recorded from previous clinical records. Result In this study, incidence of impaction was more prevalent in females. The most common pattern of impaction was mesioangular followed by horizontal, vertical, distoangular and others. The most common cause of extraction was caries in the third molar. There was no significant difference between the pattern of impaction in the right and left sides of the mandible. Conclusion Classifications of impacted mandibular third molars can be effectively used to predict the surgical difficulty and to evaluate the risk of postoperative complications. Therefore, this study highlights the importance of evaluation of pattern, type and class of impaction in Nepalese population giving a high clinical significance.

Ossifying fibromas of the mandible are more common than in the maxillary region. Juvenile ossifying fibroma has been distinguished from conventional ossifying fibroma on the basis of patient’s age, site predilection, and clinical behavior. The lesion should be differentiated from other fibro-osseous lesions as its management varies from surgical enucleation to complete resection. Present report describes the case of juvenile ossifying fibroma of anterior maxillary region in a 7 year old male patient, with a detailed description of clinical, radiographic, histopathologic features, and its surgical management. KEY WORDS Fibro-osseous lesions, Juvenile, Maxilla, Ossifying fibromaPublication Philtral Column and Nostril Shape Pattern in Nepalese Population: Comparative Study between Two Ethnic Groups of Nepal(Kathmandu University, 2024) Chaurasia, NK; Upadhyaya, C; Mahantha, S; Upadhyaya, S; Shakya, M; Upreti, S; Bhandari, A; Baral, IABSTRACT Background Knowledge of the normal appearance of lip-nose complexes in a particular ethnicity or race helps to plan and modify surgical techniques for their deformity. Objective To determine the shape of the philtral column and nostril in children of two ethnic groups (Aryans and Mongoloids) of the Nepalese population and compare them to see if any variation exists. Method The present prospective study was carried out between December 2021 to January 2023 among 200 children of age 5-12 years. The children meeting our inclusion criteria were divided equally into Aryan and mongoloid groups based on the caste system in Nepal. Facial photographs were obtained in frontal and basal views. They were analyzed to determine the shape of the philtral column and nostril shape based on Mori’s classification system. Result Out of 200 children, 123 were males and 77 were females. The most common type of philtral and nostril shape in the Nepalese population was triangular and teardrop respectively. Triangular and concave type philtral shape was predominant in Aryans whereas triangular and parallel type was predominant in Mongoloids however the variation was not significant. Similarly, teardrop nostrils were most common in both ethnic groups. Conclusion The results provide a morphological pattern and variation in the philtral and nostril shape in the two major ethnic group of Nepalese population.

Although it is a multifactorial disease, tobacco and alcohol use are the most common risk factors involved. Oral cancer has a direct relationship with deleterious habits. Inadequate knowledge about the disease and lack of awareness about its risk factors play vital role in increasing incidence of oral cancer. Objective To determine the prevalence and pattern of oral cancer as well as to find out the risk factors associated with development of oral cancer. Method The hospital records of the patients with histo-pathologically confirmed oral cancer between November 2011 to December 2021 were studied. Data regarding age, sex, associated risk factors and pattern of oral cancer were recorded. Descriptive statistics were obtained and recorded in tabulated form. Result Total of 312 (53.6%) cases out of 582 biopsies turned out to be histo-pathologically confirmed oral cancer. Out of 312 cases of oral cancer, 294 (94.27%) were squamous cell carcinoma. Total number of males were 196 (66.7%) and females were 116 (37.1%). The mean age was 56.2±13.4 years. Smoking (34.7%) was the most common risk factor and gingiva (42.6%) was the most common site of involvement. Conclusion Squamous cell carcinoma is the most common type of oral cancer and gingiva is the most common site of involvement. Tobacco smoking is the major risk factor for developing oral cancer.
