Amaç: Bu çalışmanın amacı, diş fırçalama kuvvetinin diş minesinin yüzey pürüzlülüğü, parlaklığı ve renk değişimi üzerindeki etkilerini incelemektir.
Gereç ve Yöntem: Bu çalışma, periodontal veya ortodontik nedenlerle çekilmiş 16 insan daimî kesici dişinin sağlam vestibüler mine yüzeyleri üzerinde gerçekleştirildi. Dişler rastgele 2 alt gruba ayrıldı (grup başına n=8) ve akrilik bloklara gömüldü. Vestibüler minenin başlangıçtaki yüzey pürüzlülüğü, parlaklığı ve rengi ölçüldü. Numune başına üç ölçüm yapıldı ve ortalaması alındı. 5.000 dairesel döngü (grup 1 ve 2 için sırasıyla 1.5 ve 2.5 N kuvvet ile) (MOD Dental, Türkiye) ile altı aylık diş fırçalama simülasyonu yapıldı. Ardından aynı ölçümler tekrarlandı ve veriler bağımsız örneklem ve eşleştirilmiş örneklem t-testleri ile analiz edildi (p<0.05).
Bulgular: 1.5 ve 2.5 N ile diş fırçalama simülasyonu sonrası ölçülen yüzey pürüzlülük değerleri arasında anlamlı derecede fark gözlendi (p=0,022). 1.5 ve 2.5 N kuvvet uygulandığında yüzey parlaklık değerleri anlamlı derecede azaldı (sırasıyla p=0,001, p=0,002). 2,5 N (3,48±0,83) fırçalama kuvveti ile meydana gelen renk değişimi (ΔE), 1,5 N'dan (2,42±0,86) istatistiksel olarak anlamlı derecede yüksekti (p=0,025).
Sonuç: Bu çalışmanın sonuçları uygulanan fırçalama kuvvetine bağlı olarak yüzey pürüzlülüğü ve renk değişimi değerlerinin arttığını, parlaklık değerlerinin ise azaldığını göstermiştir.

The Effect of Brushing Force on The Surface Properties and Color Stability of Dental Enamel

Öz

Aim: This study aimed to determine the effects of toothbrushing force on the surface roughness, gloss, and color change of dental enamel.
Material and Methods: This study was carried out on the sound vestibular enamel surfaces of 16 human permanent incisors extracted for periodontal or orthodontic reasons. Teeth were randomly divided into 2 subgroups (n=8, per group) and embedded in acrylic blocks. The vestibular enamel's initial surface roughness, gloss, and color were measured. Three measurements per sample were performed and averaged. Six months of toothbrush simulation with 5,000 circular cycles (with a load of 1.5 and 2.5 N for groups 1 and 2, respectively) (MOD Dental, Turkey) was performed. The same measurements were repeated and the data were analyzed with independent samples and paired sample t-tests (p<0.05).
Results: A significant difference was observed between the surface roughness values after the toothbrushing simulation with 1.5 and 2.5 N (p=0.022). Surface gloss values decreased significantly when 1.5 and 2.5 N forces were applied (p=0.001, p=0.002, respectively). Color change (ΔE) for brushing force of 2.5 N (3.48±0.83) was statistically significantly higher than 1.5 N (2.42±0.86), (p=0.025).
Conclusion: Results of this study revealed that the surface roughness and color change values increased depending on the applied brushing force whereas gloss values decreased.
