Braket Çevresindeki Mine Demineralizasyonunun Er- YAG Lazer ve Florid Uygulaması Sonrası İn-Vitro Olarak Değerlendirilmesi

Amaç: Bu in-vitro çalışmanın amacı; birlikte ve ayrı ayrı florür ve farklı dozlarda Er:YAG lazer uygulamalarının, braket çevresindeki mine yüzeyinde oluşan demineralizasyona karşı etkilerini incelemektir. Gereç ve Yöntem: Bu çalışmada 80 üst daimi 1. premolar 8 grup olarak ayrılmıştır: G1, kontrol; G2, asidik fosfat florit (AFF); G3, 0.50 W Er:YAG lazer ; G4, 0.50 W Er:YAG lazer + AFF; G5, 0.75 W Er:YAG lazer; G6, 0.75 W Er:YAG lazer + AFF; G7, 1 W Er:YAG lazer; G8, 1 W Er:YAG lazer + AFF. Braketler premolarların bukkal yüzeylerine yapıştırılmıştır. Demineralizasyon değerleri dişin gingival ve braket arasındaki bölgede DIAGNOdent yardımıyla ölçülmüştür. Son ölçümde yüzey düzensizliği Atomik Kuvvet Mikroskobu (AKM) ile belirlenmiştir. Yapay çürük lezyonu oluşturmak için tüm gruplar 5 ve 9 günlük pH siklusuna tabi tutulmuştur. Veriler Kruskal-Wallis, Friedman and Duncan istatistik testleri kullanılarak analiz edilmiştir (p

In Vitro Evaluation Of Enamel Demineralization Around The Brackets After Er-Yag Laser Irradiation And Flouride Application

Objective: The aim of this in vitro study was to investigate the effects ofa fluoridated agent and Er:YAG irradiation with different doses, alone or incombination, on enamel resistance to demineralization. Materials and Methods:This study consisted of 80 premolars divided into eight groups: G1,untreated (control); G2, Acidic Phosphate Fluoride (APF) for 4 min; G3, 0.50W Er:YAG laser; G4, 0.50 W Er:YAG laser + APF; G5, 0.75 W Er:YAG laser;G6, 0.75 W Er:YAG laser + APF; G7, 1 W Er:YAG laser; G8, 1 W Er:YAGlaser + APF. Brackets were bonded to the buccal surfaces of premolars, anddemineralization values were measured before and after treatment from thegingival aspects of the brackets, with DIAGNOdent. In last timepoint surfaceroughness was detected with Atomic Force Microscopy (AFM). All groupswere subjected to 5 and 9 days of pH-cycling to produce artificial cariouslesions. Data were tested using the Kruskal-Wallis, Friedman and Duncantests (p
