Abstract

Purpose: The purpose of this study was to evaluate the effect of different finishing and polishing systems on intrapulpal temperature of primary teeth assessed using a pulpal blood microcirculation model.
Materials and Methods: 10 sound human maxillary second primary molars used. Standardized Class V cavity preparations were performed with dentin thickness of 1 mm and restored with composite resin. The teeth divided into 6 groups with same ten samples in each group: Enhance finishing cup, Enhance PoGo polishing cup, Sof-Lex spiral finishing wheel, Sof-Lex spiral polishing wheel, Super-Snap Rainbow finishing disc, Super-Snap Rainbow super-polishing disc (n=10 per group). These 3 finishing and 3 polishing tips were applied to the restorations on the teeth with a force of 0.4 N, at a speed of 10 000 rpm for 10 seconds with the help of a slow-speed handpiece and a micromotor. The highest temperature increase were measured and noted.
Results: The highest temperature rises was seen in the Enhance finishing cup and Sof-Lex spiral finishing wheel groups with 2.3 ° C, and the lowest temperature measurement was in the Super-Snap Rainbow Super-Polishing Disc group with 1.1 ° C. Super-Snap Rainbow super-polishing disc group demonstrated significantly lower mean values in comparison with all finishing groups and Sof-Lex spiral polishing wheel. None of the groups exceeded the critical intrapulpal temperature increase of 5.6 ° C that causes irreversible damage.
Conclusion: Under these study conditions, it can be suggested that the temperature increase effects of dry applied finishing and polishing systems on primary teeth pulps are within safe limits.

Kompozit bitirme ve cilalama işlemlerinin süt dişi pulpal sıcaklık değişimine etkisi

Abstract

Amaç: Çalışmanın amacı, farklı bitirme ve cilalama sistemlerinin süt dişi intrapulpal sıcaklık artışı üzerindeki etkilerini, bir pulpal kan mikrosirkülasyon modeli yardımıyla değerlendirmektir.
Gereç ve Yöntem: Çalışma için 10 sağlam insan üst ikinci süt azı dişi kullanıldı. 1 mm dentin kalınlığı kalacak şekilde standardize sınıf V kaviteler hazırlandı ve kompozit rezin ile restore edildi. Dişler, her grupta aynı 10 örnek olacak şekilde 6 gruba ayrıldı: Enhance bitim silindiri, Enhance PoGo cilalama silindiri, Sof-Lex spiral bitim lastiği, Sof-Lex spiral cilalama lastiği, Super-Snap Rainbow bitim diski, Super-Snap Rainbow süper-cilalama diski (n=10 her grup için). Bu 3 bitirme ve 3 cilalama ucu, 0,4 N güç, 10 000 rpm hızda 10 sn boyunca düşük hızda el aleti ve mikromotor yardımıyla dişlerin üzerindeki restorasyonlara uygulandı. En yüksek sıcaklıklar ölçüldü ve not edildi.
Bulgular: En yüksek sıcaklık artışları, 2,3 ° C ile Enhance bitim silindiri ve Sof-Lex spiral bitim lastiği gruplarında, en düşük sıcaklık artışı ise 1,1 ° C ile Super-Snap Rainbow süper-cilalama diski grubunda görüldü. Super-Snap Rainbow süper-cilalama diski grubunun, her 3 bitim grubu ve Sof-Lex spiral cilalama lastiğine göre ortalama sıcaklık artışı anlamlı biçimde daha düşüktü. Hiç bir grup, geri dönüşümsüz hasara neden olan 5,6 ° C kritik pulpa içi sıcaklık artışı seviyesini geçmedi.
Sonuç: Bu çalışmanın koşulları altında, kuru uygulanan bitirme ve cilalama sistemlerinin süt dişi pulpaları üzerindeki sıcaklık artışı etkilerinin güvenli sınırlarda olduğu söylenebilir.
