Effect of Different Prophylactic Polishing Procedures on the Surface Roughness of Microhybrid and Nanohybrid Resin Composites

Abstract

Objectives: The aim of the present study was to evaluate effects of different professional dental prophylaxis procedures on the surface roughness of a microhybrid (Charisma, Heraeus-Kulzer) and a nanohybrid (Ice, SDI Dental) resin composites.

Materials and Methods: 45 disc shaped (2 mm thick /8 mm in diameter) specimens of each restorative materials (totally 90 specimens) were prepared using plexyglass mold. One side of specimens were polished with medium, fine and ultra-fine Sof-Lex (3M-ESPE) discs and 45 specimens of each composite were randomly divided into five groups (n=9). The first group received no prophylaxis treatment and served as control. The other groups received prophlaxis procedures including Detartrine paste (Septodont) with rotating rubber cup, Gelato paste (Keystone Industries) with rotating rubber cup, pumice-water slurry with rotating rubber cup and pumice-water slurry with rotating brush. After prophlaxis procedures surface roughness values of all specimens were measured using an optical prophylometer (Zygo New View 7200, Ametek). Data was statistically analyzed using Mann Whitney U and Kruskal-Wallis Tests.

Results: The smoothest surfaces were observed in control groups for both resin composites (p<0.05). Control groups’ surface roughness values of resin composites tested were significantly different (p<0.001). However there were no statistically significant differences between surface roughness values of microhybrid and nanohybrid resin composites that received same prophylaxis treatment. Gelato paste, pumice-water slurry with rotating rubber cup and pumice-water slurry with rotating brush caused significantly greater Ra values than control group but Ra values obtained with Detartrine were not significantly different from the control group in both composite.

Conclusions: All prophylaxis procedures tested in the study increased the roughness values of both composites to a level that would be retantive to bacteria. Because of that dental professional must be careful during prophylaxis procedures otherwise repolishing or rarely replacement of the composite restoration would be necessary after prophylaxis.

Farklı Profilaktik Parlatma İşlemlerinin Mikrohibrit ve Nanohibrit Kompozit Rezinlerin Yüzey Pürüzlülüğü Üzerine Etkisi

Öz

Amaç: Bu çalışmanın amacı, farklı profesyonel dental profilaksi işlemlerinin bir mikrohibrit (Charisma, Heraeus-Kulzer) ve bir nanohibrit (Ice, SDI Dental) kompozit rezinin yüzey pürüzlülüğü üzerine etkisini değerlendirmektir.

Gereç ve Yöntem: Her restoratif materyalden 45 adet disk şekilli örnek (2 mm kalınlık ve 8 mm çapında, toplam 90 örnek) plastik kalıplar kullanılarak hazırlandı. Örneklerin bir yüzü orta, ince ve ultra ince grenli Sof-Lex (3M-ESPE) disklerle parlatıldı ve her kompozitten 45 örnek rastgele beş gruba ayrıldı (n=9). İlk gruba profilaksi işlemi uygulanmadı ve kontrol grubu olarak kullanıldı. Diğer gruplar, Detartrine patı (Septodont), Gelato patı (Keystone Industries) ve pomza-su karışımının dönen lastiklerle uygulandığı ve pomza-su karışımının dönen fırçalarla uygulandığı profilaksi işlemlerine tabi tutuldu. Profilaksi işlemlerinden sonra bütün örneklerin yüzey pürüzlülük değerleri bir optik profilometre (Zygo New View 7200, Ametek) kullanılarak ölçüldü. Elde edilen veriler Mann Whitney U ve Kruskal-Wallis testleriyle istatistiksel olarak analiz edildi.

Bulgular: Her iki kompozit rezin için en pürüzsüz yüzeyler kontrol gruplarında gözlemlendi (p<0.05). Test edilen kompozit rezinlerin kontrol gruplarının yüzey pürüzlülük değerleri birbirinden anlamlı derecede farklıydı (p<0.001). Bununla birlikte aynı profilaksi işlemlerinin uygulandığı mikrohibrit ve nanohibrit kompozit rezinlerin yüzey pürüzlülük değerleri arasında istatistiksel olarak anlamlı derecede farklılık yoktu. Gelato patı, dönen lastik ve fırçayla uygulanan pomza-su karışımı kontrol grubuna oranla anlamlı derecede yüksek Ra değerlerine neden olmuştur fakat Detartrine ile elde edilen Ra değerleri her iki kompozitte de kontrol grubundan anlamlı derecede farklı değildir.

Sonuç: Çalışmada test edilen bütün profilaksi işlemleri, her iki kompozitte de yüzey pürüzlülük değerlerini bakterilerin retansiyonuna neden olabilecek seviyeye kadar yükseltmiştir. Bu sebeple diş hekimleri profilaksi işlemleri sırasında dikkatli davranmalıdır aksi taktirde profilaksi sonrası kompozit rezinlerin yeniden parlatılması veya nadiren de yenilenmesi gerekecektir.
