AbstrakEstetik gigi adalah hal yang penting bagi seseorang. Salah satu hal yang memengaruhi estetik gigi adalah warna gigi. Perubahan warna gigi dapat diperbaiki dengan pemutihan gigi hidrogen peroksida 40% dan strawberry (Fragaria x ananassa). Penelitian eksperimental laboratoris membandingkan gigi kelompok kontrol dengan dua kelompok perlakuan gigi yang diolesi bahan pemutih gigi hidrogen peroksida 40% atau direndam dalam strawberry. Penelitian dilakukan di Laboratorium Histologi Fakultas Kedokteran dan Laboratorium Kimia Universitas Padjadjaran, serta Laboratorium ITMKG Fakultas Kedokteran Gigi Universitas Padjadjaran periode Agustus 2012-Mei 2013. Kelompok masing-masing memakai sembilan buah gigi premolar permanen yang diukur ketebalan email secara mikroskopis, kadar kalsium memakai spektrofotometer, dan kekuatan tekan memakai universal testing machine. Uji statistik pengukuran ketebalan email adalah uji-t, pengukuran kadar kalsium memakai Wilcoxon dan Mann Whitney, sedangkan hasil pengukuran kekuatan gigi diuji dengan Kruskal Wallis dan Post Hoc Mann Whitney. Hasil uji penurunan ketebalan email kedua kelompok perlakuan dibandingkan dengan kontrol (uji dependent t, p=0,002 dan p=0,0001) dan perbedaan penurunan ketebalan email antara kedua kelompok (uji independent p=0,0375) adalah signifikan. Penurunan kadar kalsium kedua kelompok dibandingkan dengan kontrol (uji Wilcoxon p=0,173 dan p=0,441) dan perbedaan kadar kalsium antara kedua kelompok tersebut (uji Mann Whitney p=0,480) tidak signifikan. Uji kekuatan tekan gigi signifikan antara kontrol dan dua kelompok perlakuan (uji Kruskall Wallis p=0,014), namun bila memakai uji Post Hoc Mann Whitney hanya penurunan kekuatan tekan gigi antara kontrol dan hidrogen peroksida yang berbeda signifikan (p=0,02). Simpulan, hidrogen peroksida 40% menurunkan ketebalan email dan kekuatan tekan gigi lebih besar dibanding dengan strawberry, tetapi tidak menurunkan kadar kalsium lebih besar dibanding dengan strawberry. Teeth esthetics is important for someone. One thing influence teeth estheticsis is colour. Dental bleaching using hydrogen peroxide 40% and strawberry (Fragaria x ananassa) is conservative alternative to restore the esthetics of either stained teeth. This study was an experimental laboratory by comparing control group with two treatment groups were teeth smeared hydrogen peroxide 40% or soaked in strawberry. This study was done in Histology Laboratory Faculty of Medicine and Chemical Laboratory Universitas Padjadjaran, and ITMKG Laboratory Faculty of Dentistry Universitas Padjadjaran period August 2012-May 2013. Each group used nine permanent premolars, which will be measured email thickness microscopically, calcium levels using spectrophotometer, and compressive stregth using universal testing machine. The statistical test used for thickness measurement results email was the t-test, for measurement of calcium levels using Wilcoxon test and Mann Whitney while for tooth strength measurements were tested using Kruskal Wallis and Post Hoc Mann Whitney. The results ...

“…Although bleaching could change the surface hardness and roughness and color susceptibility of composite resin restorations, 3,4 it is still not clear whether carbamide peroxide affects their marginal seal and whether replacement of the affected restorations is necessary. …”

“…These restorations may exhibit an increase in superficial roughness and clefts, changes in microhardness and subsequently an increase in marginal microleakage. 3,4 Bailey and Swift reported that bleaching procedures affect the microparticle composite resins negatively due to their higher concentration of organic matrix compared to hybrid composite resins. They observed cracks between the resin matrix and particles in SEM analysis.…”

“…1 Dental bleaching agent is a conservative alternative and minimally invasive procedure compared with direct restorations or ceramic veneers. 2 Most of the time patients undergoing dental bleaching treatment have teeth with restorations, and the tooth-bleaching mechanism involves chemical processes, which could change the physical and mechanical properties of both dental tissue and restorative materials. 3 So the effect of bleaching agents on dental restorative materials had been reviewed recently in few years.…”

Introduction In our society, with the advances in cosmetic consciousness, well-aligned, properly contoured, white and clean teeth are a symbol of health and standard of beauty. Thus, tooth bleaching has become popular cosmetic therapy among patients and dentists. Microleakage is a major challenge to the success rate for all type of restorations. Materials and Methods Eighty maxillary human molars were collected and evaluated and Class V cavities 5×3×2 mm size were prepared with straight carbide bur (SS White) on the buccal and palatal surfaces at the cementoenamel junction of all the samples, so that the upper margin would be in enamel and lower margins on root surface. In total, 160 class V cavities were prepared on maxillary molars. Then samples were randomly divided into 3 groups (microfilled and nanohybrid composite resins and control group) and 3 subgroups (Pola Office, Whiteness HP Blue, Whiteness Perfect) according to the type of composite resins and bleaching agents used. After application of bleaching agents, all samples were immersed in a contrast solution of rhodamine B fluorescent dye for 24 hours. Then using a diamond disc samples were sectioned buccolingually through the center of the restorations and sectioned teeth were evaluated for marginal microleakage under confocal laser scanning microscope to check the extent of dye penetration. Results When all composite resin groups were compared with all the bleaching agents, at occlusal and gingival levels, lowest marginal leakage scores were obtained with the microfilled composite resin bleached with Whiteness HP blue, and in nanohybrid composite lowest microleakage score were obtained with Pola office bleach at both levels.
