Abstract

Amaç;
Bu çalışmada amaç trikalsiyum silikat içerikli materyallerin koronal diş
renklenmesine etkisinin spektofotometre ile değerlendirilmesidir

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.

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.
