Abstract

Introduction: The surgical procedure of dental implant comprising one stage surgery for the non-submerged implant design and two stages for submerged. Submerged design is frequently used in Faculty of Dentistry Padjadjaran University as it is safer in achieving osseointegration. This study has been carried out to evaluate resistant capacity of an implant component design submerged against failure based on location and the value of internal stress during the application of mastication force using the 3D Finite Element Method (FEM). Methods: The present study used a CBCT radiograph of the mandibular patient and Micro CT Scan of one submerged implant. Radiograph image was then converted into a digital model of 3D computerized finite element, subsequently inputted the material properties and boundary condition with 87N occlusion load applied and about 29N for the shear force. Results: The maximum stress was found located at the contact area between the implant and alveolar crest with stress value registered up to 193.31MPa located within an implant body where is understandable that this value is far below allowable strength of titanium alloy of 860 MPa. Conclusion: The location of the maximum stress was located on the contact area between the implant-abutment and alveolar crest. This implant design is acceptable and no failure observed under mastication load.

Abstract

Aggressive Periodontitis is one of periodontal disease that generally affects individuals less than 30 years old, with a rapid attachment loss and alveolar bone destruction. Special features of the disease are affected incisors and first molars with symmetrical bilateral destruction. The purpose of this study was to determine the prevalence and characteristics of Aggressive Periodontitis at Student Clinics, Faculty of Dentistry Padjadjaran University on May to July 2010. Based on accidentally sampling, 415 new patients at Dental and Oral Hospital, Faculty of Dentistry Padjadjaran University and Dental and Oral Polyclinic at RSUP dr. Hasan Sadikin Bandung participated in this study. Each subject filled out the questionnaire and did a clinical examination. Patients with attachment loss ≥ 4 mm were referred for radiographic and microbiologic examination to support the diagnosis. The results showed that there were 13 patients who have the diagnostic criteria of Aggressive Periodontitis. Nine patients were diagnosed as Localized Aggressive Periodontitis, and 4 patients as Generalized Aggressive Periodontitis. It is concluded that the prevalence of Aggressive Periodontitis was 3.13%, and indicated low prevalence. Characteristics of Localized Aggressive Periodontitis patients were female in 20-29 age range, whereas characteristics of Generalized Aggressive Periodontitis patients were male in 30-39 age range.

Abstract

Introduction: Periodontal disease is a multifactorial disease that attacks periodontal tissue caused by bacterial plaque and calculus, and also nutritional deficiency. Applying a healthy dietary habit will be able to prevent the occurrence of periodontal disease. The purpose of this study was to discovered description of the Healthy Eating Plate habit and periodontal health knowledge in undergraduate students of Faculty of Dentistry Universitas Padjadjaran. Method: This research was quantitative with two questionnaire instruments; the first contained the food variety and the proportion consumed by respondents, and the second contained questions regarding the periodontal health. The samples were as much as 137 undergraduate students of Faculty of Dentistry Universitas Padjadjaran batch 2015, taken with an accidental random sampling technique. Results: The nutritional proportion of all respondents were as follows: at breakfast, 27.5% of carbohydrate, 25.1% of protein, 24.3% of vegetables, and 23.4% of fruits; at lunch, 29.1% of protein, 27.1% of carbohydrates, 19.8% of vegetables, and 24.4% of fruits; at dinner, 27% of protein, 23% of carbohydrate, 20.9% of vegetables, and 20.1% of fruits. The level of periodontal knowledge was 68.94%. Conclusion: The respondents dietary habit was close enough to the indicators of the Healthy Eating Plate, with a moderate level of periodontal health knowledge.

Abstract

Pendahuluan: Diabetes mellitus adalah penyakit disregulasi metabolisme yang disebabkan oleh defisiensi fungsional aksi insulin dan bermanifestasi pada berbagai organ tubuh termasuk rongga mulut. Diabetes mellitus merupakan modifying factor penyakit periodontal karena dapat memperburuk respon jaringan periodontal terhadap iritasi plak bakteri. Akumulasi plak dapat diukur dari tingkat kebersihan mulut seseorang. Penelitian ini bertujuan untuk mengevaluasi tingkat kebersihan mulut penderita diabetes mellitus tipe 1 di RSUP Dr. Hasan Sadikin, RSUD Ujung Berung dan RS Al Islam Bandung. Metode: Sebanyak 16 penderita diabetes mellitus tipe 1 berusia 16-48 tahun diperiksa kebersihan mulutnya menggunakan Oral Hygiene Index-Simplified (OHI-S) dari Greene dan Vermillion (1964). Hasil: Rata-rata skor OHI-S sebesar 1,905, berdasarkan OHI-S, skor tersebut berada dalam kriteria sedang. Simpulan: Kebersihan mulut penderita diabetes mellitus di RSUP Hasan Sadikin, RSUD Ujung Berung dan RS Al Islam tergolong dalam kategori sedang. ABSTRACTIntroduction: Diabetes mellitus is a metabolic dysregulation disease caused by a functional deficiency of insulin action and manifests in various organs including the oral cavity. Diabetes mellitus is a modifying factor for periodontal disease because it can worsen the response of periodontal tissues to bacterial plaque irritation. Plaque accumulation can be measured from the level of ones oral hygiene. This study aims to evaluate the level of oral hygiene of type 1 diabetes mellitus patients at Dr. Hasan Sadikin Hospital, Ujung Berung Hospital, and Al Islam Hospital Bandung. Methods: 16 patients with type 1 diabetes mellitus aged 16-48 years were examined for oral hygiene using the Oral Hygiene Index-Simplified (OHI-S) from Greene and Vermillion (1964). Result: The average OHI-S score is 1.905, based on OHI-S, the score is in the medium criteria. Conclusion: Oral hygiene of diabetes mellitus patients at Hasan Sadikin General Hospital, Ujung Berung Regional Hospital, and Al Islam Hospital is classified as moderate.Keywords: Diabetes mellitus type 1, oral hygiene, Oral Hygiene Index-Simplified.
