Amaç: Estetik olarak dişlerinden memnun olmayan genç bireyler kendilerinin uygulayabileceği beyazlatma ürünlerine süpermarket, eczane ve internetten kolaylıkla ulaşabilirler. Bu ürünlerin genç daimi dişlerin minesi üzerine kontrolsüz uygulanmasının etkileri bilinmemektedir. Bu çalışmada kişiler tarafından uygulanabilen farklı diş beyazlatma ürünlerinin genç daimi dişler üzerine etki ve etkinliğinin in vitro olarak değerlendirilmesi amaçlandı. Gereç ve Yöntem: Ortodontik tedavi amacıyla çekilmiş 84 genç daimi premolar diş rastgele 7 gruba ayrıldı. EBright Light Accelerated Teeth Whitening SystemTM , Luster 1 Hour WhiteTM, White Light Teeth Whitening SystemTM, WhitedentTM, Crest 3D White WhitestripsTM, Purewhite Whitening TraysTM, Spray White 90TM üretici firmaların önerilerine göre diş gruplarına uygulandı. Materyaller dişlere uygulanmadan önce, uygulandıktan sonra ve termal siklusu takiben minelerin mikrosertlik, yüzey pürüzlülüğü, yüzey morfolojisi ve renk ölçümleri yapıldı. Sonuçlar istatistiksel olarak değerlendirildi. Bulgular: Kullanılan bütün ürünler dişlerde beyazlatma sağladı. Uzun dönemde minenin mikrosertliğine olumsuz bir etki gözlenmedi (p>0.05). Pure White Whitening TraysTM grubunda beyazlatma sonrası pürüzlülük artarken, diğer gruplarda istatistiksel olarak anlamlı bir değişiklik olmadı (p>0.05). Genel olarak yüzey pürüzlülüğü termal siklus sonrasında artarken, SEM değerlendirmelerinde hiçbir grupta mine prizmalarını açığa çıkartacak kadar bozulma olmadığı saptandı. Sonuç: Çalışmada kullanılan ürünlerin genç daimi dişlerin mine yüzeylerinde minimal düzeyde değişiklik oluşturduğu ve Crest 3D White WhitestripsTM in daha güvenle kullanılabileceği sonucuna varıldı
Purpose: Young individuals who are not aesthetically satisfied with their teeth can easily access the whitening products they can apply through the supermarkets, pharmacies and the internet. The effects of uncontrolled application of these products on the mines of young permanent teeth are unknown. This study was aimed at evaluating in vitro the effects and effectiveness of different tooth whitening products that can be applied by individuals on young permanent teeth. Tools and Methods: 84 youth permanent premols taken for the purposes of orthodontic treatment were randomly divided into 7 groups. The E-Bright Light Accelerated Teeth Whitening SystemTM, Luster 1 Hour WhiteTM, White Light Teeth Whitening SystemTM, WhitedentTM, Crest 3D White WhitestripsTM, Purewhite Whitening TraysTM, Spray White 90TM were applied to dental groups according to the recommendations of manufacturers. Before, after, and after the thermal cycle, the materials were applied to the teeth, the microserity, surface smoothness, surface morphology and color measurements were made. The results were statistically evaluated. Results: All the products used provided whitening in the teeth. There has been no negative impact on the microsensity of the mine over a long period of time (p>0.05). In the Pure White Whitening TraysTM group, after whitening smoothness increased, while in other groups there was no statistically meaningful change (p>0.05). In general, the surface smoothness increased after the thermal cycle, and SEM assessments found that there was no disturbance enough to reveal mine prisms in any group. The study found that the products used in the study made minimal changes in the mining surfaces of young permanent teeth and that Crest 3D White WhitestripsTM could be used safer. Keywords: Whitening agents, tooth whitening, child, in vitro. EFFECTS OF OVER THE COUNTER BLEACHING PRODUCTS (OTC) ON THE COLOR, MICROHARDNESS, SURFACE ROUGHNESS AND MORPHOLOGY OF THE YOUNG PERMANENT TEETH ENAMEL ABSTRACT Aim: Esthetically unsatisfied young individuals can access self-applicable teeth whitening products (over the counter-OTC) from the supermarkets, pharmacies or on the internet easily. Effects of uncontrolled application of whitening products on the enamel surfaces of young permanent teeth is unknown. In this study, it is aimed to evaluate the effectiveness and impact of some different individual self-applicable teeth whitening products on young permanent teeth as an in vitro activity. Material and Methods: Eighty-four young permanent teeth extracted for orthodontic treatment, were randomly distributed into 7 groups. Seven different OTC teeth whitening products; E-Bright Light Accelerated Teeth Whitening SystemTM, Luster 1 Hour WhiteTM, White Light Teeth Whitening SystemTM, WhitedentTM, Crest 3D White WhitestripsTM, Purewhite Whitening TraysTM, Spray White 90TM, applied to tooth groups according to the manufacturers' recommended application procedures. Color, enamel microhardness, surface roughness and morphology were evaluated before bleaching, after bleaching and after thermal cycling. Obtained data were statistically assessed. Results: All of the OTC products were capable of whitening the teeth. It is seen that OTC products do not have any long-term negative impact on microhardness of enamel(p>0.05). Surface roughness increased after bleaching in Pure White Whitening TraysTM group, changes in roughness in the other groups were not statistically significant(p>0.05). Overall, it is observed that surface roughness increased after the aging process and considering the results of SEM, none of the groups had enough corruption on the morphology of the enamel to expose enamel prisms. Conclusion: We concluded that the products used in this study caused minimal changes on emal surfaces of young permanent teeth and the use of Crest 3D White WhitestripsTM can be safer than other studied products.
