Abstract

Disc displacement with reduction is one of the temporomandibular joint disorders which often occurred. Disc displacement can cause the changing of condyle position which can be evaluated by using radiograph. Cone Beam Computed Tomography (CBCT-3D) is a radiograph for viewing of the condyle with more accurate. The aim of this study was to determine the condyle position in disc displacement with reduction. Sample was 11 patients with disc displacement and 3 asymptomatic patients as control. A radiographic exposure was done with CBCT-3D and measurement of joint space in sagittal view was performed. Statistical analysis used T-test. The result of this study showed that there was significant difference (p<0,05) between disc displacement with reduction and asymptomatic patients. It can be concluded that there was different condyle position between disc displacement with reduction and asymptomatic patients. It means condyle position displacement caused sagittal joint space changed.

Abstract

Sodium Hipoklorit (NaOCl) merupakan desinfektan yang sangat efektif untuk membersihkan basis gigi tiruan.Namun, penggunaan dari bahan kimia ini dapat menurunkan kekuatan impak dari basis resin akrilik. Penelitianini dilakukan untuk mengetahui pengaruh larutan sodium hipoklorit dengan konsentrasi 2% dan 5% terhadapkekuatan impak basis gigi tiruan resin akrilik. Penelitian ini menggunakan 30 spesimen resin akrilik QC-20berukuran 50 x 6 x 4 mm. Spesimen dibagi ke dalam 3 kelompok perendaman; konsentrasi 2% NaOCl, 5%NaOCl dan kelompok kontrol. Perendaman dilakukan selama 5 hari 1 jam 40 menit yang mensimulasipemakaian larutan desinfektan selama 1 tahun. Masing-masing kelompok perendaman diuji dengan charpyimpact tester dengan kecepatan impak sebesar 2,9 m/detik dan energi pendulum sebesar 1 joule. Dataselanjutnya dianalisis dengan Analisis Varian (ANOVA). Hasil analisis menunjukkan bahwa terdapat perbedaanyang signifikan (p< 0,05) antara larutan perendaman terhadap kekuatan impak. Sebagai kesimpulan, larutansodium hipoklorit dapat menyebabkan perubahan kekuatan impak basis gigi tiruan akrilik.
