FARKLI KİMYASAL YAPILARA SAHİP DİŞ MACUNLARININ FELDSPATİK PORSELENİN YÜZEY PÜRÜZLÜLÜĞÜNE ETKİSİ

Amaç: Bu çalışmanın amacı, farklı kimyasal yapılara sahip diş macunlarının feldspatik porselenin yüzey pürüzlülüğüne etkisinin incelenmesidir. Gereç ve Yöntem: Çalışma kapsamında toplam 40 adet disk şeklinde porselen örnek kullanıldı. Örneklerin yüzey bitim ve cila işlemlerinden sonra profilometre cihazı ile pürüzlülükleri ölçülüp kaydedildi ve rastgele dört gruba ayrıldı. Örnek yüzeyleri dört farklı kimyasal yapıya sahip diş macunu ve elektronik diş fırçası ile günde iki kere iki dakika olmak üzere toplam bir aya denk gelecek şekilde iki saat boyunca fırçalandı. Birinci ayın sonunda profilometre ile tekrar yüzey pürüzlülükleri ölçüldü ve kaydedildi. Verilerin istatistiksel değerlendirmesi varyans analizi kullanılarak yapıldı. Bulgular: Varyans analizinin sonuçları farklı kimyasal yapıdaki diş macunlarının feldspatik porselenin yüzey pürüzlülüğünü anlamlı derecede arttırdığını (p<0.05) gösterdi. En yüksek pürüzlülük değeri (2.60 ± 0.48 µm) siyah renk koduna sahip diş macununda, en düşük pürüzlülük değerinin ise (1.96 ± 0.43 µm) kırmızı renk koduna sahip diş macununda olduğu tespit edildi. Sonuç: Elde edilen verilere göre, diş macunlarının feldspatik porselenin yüzey pürüzlülüğünü arttırdığı, macunların kimyasal içeriğine bağlı olarak da bu artışın değişebildiği sonucuna varıldı.

After the surface polishing, the surface roughness of specimens was measured by profilometer and divided into four groups randomly. The surface of specimens was brushed two hours instead of two times a day through two minutes for a month by electric toothbrush and toothpastes, which have four different chemical compositions. After a month the surface roughness were measured by profilometer again and recorded. The statistically analysis obtained data were performed with repeated measures analysis of variance test.Results: The results of variance test showed that statistically significant differences between different chemical composition toothpastes on surface roughness of feldspathic porcelain (p<0.05). The highest surface roughness value (2.60 ± 0.48 µm) was identified in black color code toothpaste, the lowest surface roughness value (1.96 ± 0.43 µm) was identified in red color code toothpaste.Conclusion: The obtained data presented that, the toothpastes have increased the surface roughness of feldspathic porcelain and this increasing has changed depending on the chemical composition of toothpastes.Keywords: Toothpaste, porcelain, surface roughness
