TRİKALSİYUM SİLİKAT İÇERİKLİ ÜÇ FARKLI ENDODONTİK MATERYALİN SEBEP OLDUĞU KORONAL DİŞ RENKLEŞMESİNİN SPEKTROFOTOMETRİK ANALİZ YÖNTEMİ İLE DEĞERLENDİRİLMESİ
Abstract
Gereç ve Yöntem; Bu çalışmada 50 adet maksiller santral diş kullanıldı. Dişler rastgele 5 gruba (n=10) ayrıldı. Dişler 37 °C in % 100 nemli ortamda bekletildi. Diş köklerinin apikal kısımları, mine-sement birleşiminin 2 mm apikalinden elmas frezlerle uzaklaştırıldı. Ardından apikal giriş, Gates Glidden frezler 1 numaradan 6 kadar kullanılarak genişletildi. Gruplar; Negatif kontrol grubu, Biodentin, Bioaggregate, ProRoot MTA ve Pozitif kontrol grubu (defibrine koyun kanı) olarak belirlendi. Reperatif materyal 2 mm kalınlıkta olacak şekilde kaviteye yerleştirilip cam iyonomer siman ile kavite girişi kapatıldı. Renk ölçümünde Vita Easyshade Advance spektrofotometre kullanıldı. Materyaller yerleştirilmeden önce (T0), yerleştirildikten sonra 1. Hafta (T1), 2. Hafta (T2), 1 ay (T3) ve 2 ay (T4) olmak üzere 5 defa ölçüm yapılarak renk değişim miktarları (∆E) değerlendirildi. Commission Internationale de l'eclairage L*a*b* değişimleri her grup için ölçülerek karşılaştırıldı.
Bulgular; Negatif kontrol grubu,
biodentin ve bioaggregate gruplarında, diş kronunda anlamlı derecede renk
değişikliği görülmedi. Ayrıca bu gruplar ProRoot MTA ve Pozitif kontrol
grubuna göre daha az renkleşmeye sebep oldular .Pozitif kontrol grubu ve
ProRoot MTA gruplarında 2 aylık değerlendirme sürecinde L* değerlerinin düştüğü
ve zaman ilerledikçe örneklerin renginin koyulaştığı gözlendi.
Sonuç; Estetiğin önem kazandığı ön grup dişlerde, MTA’ya alternatif olarak, trikalsiyum silikat içerikli Biodentine veya Bioaggregate gibi dentin tamir materyalleri tercih edilebilir.

IN VITRO SPECTROPHOTOMETRIC ANALYSİS OF CORONAL TOOTH DISCOLORATION INDUCED BY THREE DIFFERENT TRICALCİUM SILICATE BASED ENDODONTIC MATERIALS
ABSTRACT
Aim;. The aim of this study is to evaluate the coronal tooth discoloration caused by the materials used in such applications, by using spectrofotometre.
Material and Methods; Fifty extracted human maxillary central incisor teeth were used in this study. Teeth were randomly assigned into 5 groups (n = 10) and stored in saline solution at 37 °C in 100% humidity. Apical part of the root, was removed 2 mm below the semento-enamel junction. Then apical access cavity was made in 5 groups and prepared by using Gates Glidden files (Dentsply, Maillefer, USA) at number 1 to 6. The groups were as follows: Negative control group, Biodentin, Bioaggregate, ProRoot MTA and Positive control group (bovine animal blood). A 2-mm-thick increment of reparative material was placed on the pulpal floor, covered by glass ionomer cement. Color change was evaluated with Easyshade Advance Spectrophotometer at 5 time points: day 0 (T0), day7 (T1), day 14 (T2), 1 month (T3) and 2 months (T4). Changes in Commission Internationale de l'eclairage L*a*b* were measured for each experimental group and compared with each other.
Results; There were no significant differences between negative control group, biodentin and bioaggregate group. These groups produced significantly less discoloration than ProRoot MTA and positive control group. There were significant drops in the values of L* from T0 to T4 in the Positive control group and ProRoot MTA group. The values decreased over time as the samples became darker..
Conclusions; Tricalcium Silicate based materials such as Biodentine or Bioaggregate can be prefer instead of MTA in the anterior teeth, where the esthetic outcome is very important.
