The use of removable dentures is one of the main approach to oral rehabilitation of partially or completely edentulous patient. Denture hygiene is an important things for the elderly as a vulnerable people. The purpose is to discribe both of the literature or recent study that related to denture hygiene in elderly. Removable denture got special attention cause accumulate food residue, bacterial biofilm, and calculus at the mucosa or denture interface. Recently, the presence of bacterial bioflim on denture was considered a risk factor for aspiration pneumonia in frail older people. In general, removable denture that is used acrylic based denture.The microporous surfaces of an acrylic denture provide a wide range of environments to support microorganisms that can threaten the health of patient. Knowing denture cleanser as apart of denture hygiene in elderly is an important things.

Pendahuluan: Bruxism adalah aktivitas parafungsi oklusal pada siang atau malam hari dimana terjadi grinding, clenching, dan gnashing. Bruxism dapat memberikan tekanan berlebih pada tulang sehingga tulang beradaptasi melalui proses remodeling tulang yang dapat mengubah jumlah, densitas, dan ketinggian tulang. Perubahan yang terjadi pada tulang dapat dianalisis dengan mengukur ketinggian tulang kortikal mandibula. Salah satu metode pengukuran yang dapat digunakan adalah indeks panoramik mandibula (PMI) melalui radiografi panoramik. Tujuan penelitian ini adalah menganalisis perbedaan ketinggian tulang kortikal mandibula pada penderita dan bukan penderita bruxism. Metode: Jenis penelitian ini adalah analitik cross sectional. Sampel penelitian ini terdiri dari dua kelompok, yaitu 30 sampel radiograf panoramik digital penderita bruxism dan 30 sampel radiograf panoramik digital bukan penderita bruxism. Data dianalisis menggunakan independent t-test pada software MegaStat 10.1. Hasil: Hasil analisis p-value menunjukkan ketinggian tulang kortikal mandibula regio kanan penderita bruxism dan bukan penderita bruxism adalah 0,1517mm dan regio kiri adalah 0,2036mm (p-value>0,05). Simpulan: Tidak terdapat perbedaan ketinggian tulang kortikal mandibula antara penderita bruxism dan bukan penderita bruxism.Kata kunci: Bruxism, kortikal mandibula, indeks panoramik mandibular. ABSTRACTIntroduction: Bruxism is an occlusal parafunction activity during the day or night that includes grinding, clenching, and gnashing. Bruxism can exert excessive pressure on the bone so that the bone adapts through the process of bone remodelling, which can change the amount, density, and height of the bone. Changes that occur in the bone can be analysed by measuring the height of the mandibular cortical bone. One of the measurement methods commonly used was the panoramic mandibular index (PMI) through panoramic radiography. The purpose of this study was to analyse the differences in the height of the mandibular cortical bone in bruxism and non-bruxism patients. Methods: The type of research was cross-sectional analytic. The sample of this study consisted of two groups, which were 30 samples of digital panoramic radiographs of bruxism patients and 30 samples of digital panoramic radiographs of non-bruxism patients. Data were analysed using an independent t-test in the MegaStat 10.1 software. Results: The results of the p-value analysis showed that the mandibular cortical bone in the right region of bruxism and non-bruxism patients was 0.1517 mm, and in the left region was 0.2036 mm (p-value > 0.05). Conclusion: There is no difference in the mandibular cortical bone height between bruxism and non-bruxism patients.Keywords: Bruxism, mandibular cortical bone, panoramic mandibular index.

Physiologically, the human teeth must fit into the jaw relationship harmony, not vice versa. In order to produce full dentures that fit into the harmony of the jaw, the denture teeth arrangement should be made according to the balanced occlusion principle. One of the most important factors in the principle is condylar angle adjustment. Objectives: To compare the condylar angle average values between the complete dentulous and totally edentulous subjects in Deutero-Malay. Methods: This was a descriptive comparative clinical research, that involved 16 complete dentulous Deutero-Malay dental students and 14 totally edentulous Deutero-Malay patients at Oral and Dental Hospital of Faculty of Dentistry Padjadjaran University who fullfilled the inclusion criteria. The condylar angle value measurement was done with protrusive record method using the fully-adjustable arcon type articulator. Results: The average value of the complete dentulous Deutero Malays' condylar angles was 38.0±8.5° and the average value of the totally edentulous Deutero-Malay' was 30.7±14.6°. Statistically, there was a significant difference between the condylar angle's average value of the complete dentulous and the totally edentulous in the Deutero-Malay. Conclusion: There was a condylar angle decrease on complete edentulous subjects compared to the fully dentulous subjects in Deutero-Malay. ABSTRAK Perbedaan sudut kondilus antara subjek bergigi dan tidak bergigi pada Deutero-Malay. Secara fisiologis, gigi manusia harus sesuai dengan harmonisasi hubungan rahang, namun tidak sebaliknya. Untuk dapat menghasilkan gigi tiruan lengkap yang sesuai dengan harmonisasi hubungan rahang, pengaturan gigi harus dibuat sesuai prinsip oklusi seimbang. Salah satu faktor terpenting dalam prinsip oklusi seimbang adalah penyesuaian sudut kondilus. Tujuan: Membandingkan rerata nilai sudut kondilus antara subjek bergigi lengkap dengan subjek yang tidak bergigi pada Deutero-Malay. Metode: Penelitian ini adalah penelitian klinis deskriptif komparatif. Sampel penelitian adalah 16 mahasiswa kedokteran gigi dengan subras Deutero Malay yang bergigi lengkap dan 14 pasien tidak bergigi Deutero Malay pada Rumah Sakit Gigi dan Mulut Fakultas Kedokteran Gigi Universitas Padjajaran, yang telah memenuhi kriteria inklusi. Pengukuran nilai sudut kondilus dilakukan dengan metode pencatatan protrusif menggunakan artikulator tipe fully adjustable arcon. Hasil: Nilai rata-rata sudut kondilus dari Deutero-Malay bergigi lengkap adalah 38,0+8,5 o dan rerata nilai sudut kondilus dari Deutero-Malay tidak bergigi adalah 30,7±14,6°. Secara statistik, terdapat perbedaan bermakna antara nilai rerata sudut kondilus pada subjek bergigi lengkap dengan yang tidak bergigi pada Deutero-Malay. Simpulan: Terdapat penurunan sudut kondilus subjek yang tidak bergigi dibandingkan dengan sudut kondilus subjek bergigi lengkap pada Deutero-Malay.

The porcelain-fused-to-metal crown is the most popular indirect restoration in dentistry due to its high fracture resistance and low cost. However, unaesthetic labial margin is unacceptable to patients. Metal collar causes dark discoloration, which is worsened by gingival recession. Modification in metal collar coping has been developed to combine high fracture resistance of metal and high aesthetic of porcelain. Modification in crown fabrication including structure and composition of both nickel chromium alloy and feldspathic porcelain; application of self-cured resin cement and digital method; is meant to improve aesthetics without compromising fracture resistance. This study was an experimental laboratory research to evaluate fracture resistance of porcelain-fused-to-metal crowns with different metal coping designs. A total of 20 samples were used and divided into 4 groups according to different coping designs: (1). full metal collar; (2). full metal collarless; (3). modified metal collarless with 1.5 mm reduction; (4). modified metal collarless with 2 mm reduction. Universal Testing Machine (LRXPlus, Lloyd) was used to measure fracture resistance of all crowns. Average fracture resistance value for group 1 was 988.42 N; Group 2 was 1180.15 N; Group 3 was 1089.47 N; Group 4 was 1202.61 N. The results of statistical analysis showed that there was a difference in fracture resistance among porcelain-fused-to-metal crowns with different coping designs, although the value was not statistically significant. The higher coping reduction at labial margin, the higher the fracture resistance and standard deviation.

Denture adhesive is a device that applied to the base of a denture before the denture is inserted into the mouth. The device used to improve denture retention and stabilization. It was thought that added antifungal agent to denture adhesive might be an effective way to inhibit the growth of Candida albicans and prevent denture stomatitis.The study was performed as an experimental laboratory study by an observed antifungal test of denture adhesive against Candida albicans growth using Kirby Bauer diffusion agar method with 5 samples and 3-time repetitions. The conclusion of this study was that the antifungal agent in denture adhesive containing poly (methylvinylether/maleic acid), sodium-calcium mixed partial salt and propyl hydroxybenzoate and denture adhesive containing sodium carboxymethylcellulose couldn't inhibit the growth of Candida albicans.
