Publication A Study of Assessment of Partial Edentulous Patients Based on Kennedy’s Classification at Dhulikhel Hospital Kathmandu University Hospital(Kathmandu University, 2013) Sapkota, B; Adhikari, B; Upadhaya, CABSTRACT Background Oral health contributes significantly towards quality of life(QOL). Edentulousness falls in a special category among the various conditions of dental origin. Dietary intake and nutritional status is affected by poor oral health and loss of teeth. This will ultimately compromise general health. Objective To identify the frequency of Kennedy’s classification among partial edentulous patients and to compare occurrence among gender and between upper and lower arches and also to compare edentulousness among employed and unemployed population. Methods This study was carried out at Dhulikhel Hospital Dental Department. The study was conducted randomly among 194 patients in dental OPD who were partially edentulous. A structured pro forma was used to find out the edentulousness based on Kennedy,s classification. Results Among the Kennedy’s classification ClassIII was found to be most common. Among them females and unemployed group were found to have more edentulousness and upper arch was more common. It was also found that females were more conscious and get the replacement of missing teeth among which those having Class IV missing were replaced most often. Conclusion The Kennedy Class III partial edentulousness type is most commonly found in this study. KEY WORDS Edentulousness, kennedy’s classificationPublication Assessment of The Relationship of Incisive Papilla to Maxillary Central Incisor and Canine-Papilla-Canine Line among the Dentate population of Central Nepal(Kathmandu University, 2017) Sapkota, B; Srii, R; Srivastava, S; Marla, V; Koju, SABSTRACT Background Incisive papilla has been used as a fixed anatomical landmark to guide in teeth arrangement. Objective To assess the relationship of distance from central incisor to incisive papilla with various types of arch forms, shapes of incisive papilla and types of canine-papilla- canine relation. Method Two hundred maxillary stone casts were prepared. Eighteen casts were excluded as they had voids and the final study was carried out in 182 participants. The arch form was assessed according to Testut L. and shape of incisive papilla was recorded according to Filho IE et al. A digital Vernier caliper was used to measure the distance from posterior point of incisive papilla to the mesio-incisal edge from the labial side of maxillary central incisor. The inter-canine line was drawn and its position with incisive papilla was assessed. The analysis was done using SPSS version 20.0. One way ANOVA was done. Result Result showed that parabolic type of arch was the most common i.e. 76.4%. Mean distance of central incisor to incisive papilla was 11.093±1.894 mm. No significant difference was observed in the distance of Central incisor to Incisive Papilla among different arch forms (p=0.854) and various shapes of incisive papilla (p=0.091). The mean distance of central incisor to incisive papilla was significantly greater when canine-papilla-canine line passed from the middle than from posterior part of incisive papilla. Conclusion These results suggest that incisive papilla is a reliable biometric guide which would help to reduce the clinical time of both the dentist and the patients in placement of the anterior teeth.

Objective The aim of this study was to assess the level of edentulousness, the cause of edentulousness, the denture wearing and denture needs of selected Nepalese population. It will also analyze how factors, such as habits, built, educational needs influence edentulousness. Method Patients visiting the Dental Outpatient Department of Dhulikhel Hospital and various dental camps organized by the hospital were selected for study. The examination was conducted using basic diagnostic tools (Mouth mirror, straight probe and explorer). Statistical software SPSS 16.0 was used for data analysis, chi-square test was performed for each parameter. Result The statistical analysis showed that age was statistically associated to edentulousness, but gender and built were not associated to edentulousness. Furthermore educational status and habit were statistically associated with edentulousness. Conclusion Oral health awareness and education programs should be conducted at the community level for every individual. The role of oral hygiene practice, the negative effect of various oral habit, especially smoking and tobacco chewing habits, the need to replace missing teeth and care of artificial denture should be explained.

The mandibular anterior fixed bridge often presents problems to the dentist due to the size of the natural teeth and their visibility. In addition, due to high cost factor, many patients are not able to afford fixed partial denture for missing anterior teeth. This article describes a cost effective technique for the restoration of missing mandibular anterior teeth by fabrication of full coverage crowns and resin-bonded fixed bridge combination. KEY WORDS Crown, Mandibular anterior teeth, Resin-bonded bridgePublication Oral Hygiene and Gingival Health in Patients with Fixed Prosthodontic Appliances - A Six Month Follow-up(Kathmandu University, 2015) KC, Basnyat S; Sapkota, B; Shrestha, SABSTRACT Background Gingival inflammation and periodontal disease are the common complications of fixed dental prosthesis. They can be overcome by good oral hygiene maintenance. Objective The objective of this study was to assess the oral hygiene and gingival condition in patients after placement of fixed dental prosthesis for a period of six months. It was also analyzed how factors like type of fixed dental prosthesis (Single crown, fixed partial denture) and material (Metal, Porcelain fused to metal) are statistically associated with oral hygiene and gingival health. Method The sample consisted of 50 patients visiting the Dental Outpatient Department of Dhulikhel Hospital. The oral examinations were conducted using basic diagnostic tools (Mouth mirror, periodontal probe and explorer). Teeth and gingiva were examined using the Plaque and Gingiva Index by Silness and Löe. The examinations were conducted after 14 days and six months after placement of fixed dental prosthesis along with the oral hygiene instructions. Paired sample t-test were done to find statistical association using SPSS 16.0. Result Our results revealed no significant difference in plaque index among patients with single crown whereas fixed partial denture showed statistical significance. No significant differences were found for type of material. The statistical analysis showed similar results for gingival index. Conclusion Our research showed that single crown had no significant difference on Plaque index and Gingival index of the patient after 14 days and six months, whereas, Fixed partial denture showed significant difference. Both metal and porcelain fused to metal crown revealed no statistically significant difference on Plaque index and Gingival index.

To maintain harmony of the occlusal condition, the posterior teeth must pass close to but not contact their opposing teeth during mandibular movement. Anterior guidance is essential to a harmonious functional relationship in the masticatory system. Objective The objective of this study was to find out the frequency of pattern of occlusal contacts in lateral position and to compare the accuracy of shim-stock and articulating paper. Method This study was conducted in the Department of Prosthodontics, Kathmandu University School of Medical Sciences. The study consisted of 80 healthy subjects between the age group of 18-30 years. They were selected randomly from undergraduate students and dental hygienist of college of dental science and written consent was taken. This age was selected because of minimal occlusal wear. Results In the present study with 80 participants the majority of the contact patterns with shimstock on the working side were group function( 84%), the canine protected occlusal patterns were found to be 12% and the unclassifiable pattern were found to be 4%. On the otherhand, the data with articulating paper were group function type (94%), the canine protected occlusal patterns as 2.5% and the unclassifiable pattern were found to be 3.5%. In this study, with shim stock, the majority of the contact patterns were group function being 84% whereas with the articulating paper it was 94%. When shim stock occlusal strip (12 μm thick) was compared to commonly used articulating paper (40 μm), the excessive thickness of articulating paper that exceed the maximum recommended thickness of occlusal recording strips markedly must have given much more false contacts. Conclusion It was concluded that the majority of the contact pattern were group function being 84% with shim stock and 94% with articulating paper. Also shim stock exhibits superior accuracy and reliability. KEY WORDS Canine guided, GPT, group function, nonworking side, unclassified pattern, working side.
