FARKLI KONSANTRASYONLARDA KULLANILAN FİTİK ASİT SOLÜSYONLARININ KÖK KANAL DENTİN MİKROSERTLİĞİ ÜZERİNDEKİ ETKİLERİ
Abstract
Amaç: Bu
çalışmanın amacı farklı konsantrasyonlarda kullanılan fitik asit
solüsyonlarının dentin mikrosertliği üzerindeki etkilerinin araştırılmasıdır.
Gereç ve Yöntem: Bu çalışmada 75 adet
tek köklü, apikal gelişimini tamamlamış çekilmiş alt premolar dişleri
kullanıldı. Koronal giriş kaviteleri bir rond frezle su soğutması altında
açıldı. Kanala ilk giriş #15 K-tipi eğe ile yapıldı. Kanal içine yerleştirilen
paslanmaz çelik #15 K- tipi endodontik kanal eğesinin apekste görün- düğü andan
itibaren eğe 1 mm geri çekilerek çalışma boyu tespit edildi. Protaper Universal
eğeleri kulanı- larak F3 numaralı eğeye kadar preparasyon yapıldı. Daha sonra,
dişler her grupta 15 adet olacak şekilde rastgele 5 gruba ayrıldı. Son
irrigasyon solüsyonları; %17 EDTA, %1 Fitik asit, %0.5 Fitik asit, %5 NaOCl ve
distile sudur. Kökler elmas diskler kullanılarak longi- tudinal olarak ikiye
ayrıldı. Son irrigasyon prosedürleri uygulanmadan önce her örneğin koronal,
orta ve api- kal üçlü seviyelerinden başlangıç mikrosertlik değerleri ölçüldü.
Son yıkama prosedürleri uygulanıp, yeniden ölçümler yapıldı. İstatistiksel
değerlendirme tek yönlü varyans analizi (ANOVA) ve Post-hoc Tukey HSD ile
yapıldı.
Bulgular: Koronal ve orta üçlü seviyesinde
gruplar arasında istatistiksel olarak anlamlı bir farklılık izlen- mezken
(p>0.05), apikal üçlü seviyesinde %1 Fitik asit grubu istatistiksel olarak
anlamlı düzeyde dentin mikrosertliğinde azalmaya neden olmuştur (p<0.05).
Kökün tüm seviyelerinde, %0.5 Fitik asit solüsyonu, diğer gruplarla
karşılaştırıldığında anlamlı farklılığa neden olmamıştır (p>0.05). NaOCl ve
distile su grubu tüm seviyelerde diğer gruplardan farklı bulunmuştur (p<0.05).
Her iki grup da dentin mikrosertliğinde azalmaya neden olmamıştır.
Sonuç: Koronal ve orta üçlü seviyesinde gruplar arasında herhangi bir farklılık
gözlenmezken, %1 Fitik asit solüsyonu apikal üçlü seviyesinde dentin
mikrosertliğinde azalmaya neden olmuştur.

EFFECT OF DIFFERENT CONCENTRATIONS OF PHYTIC ACID SOLUTIONS ON ROOT
CANAL DENTINE MICROHARDNESS
Aim: The purpose of this study is to evaluate the effect of different
concentrations of phytic acid solution on root canal dentine microhardness.
Material and
Methods: 75 single rooted mandibular premolar teeth with a
closed apex were used for this study. Teeth with an average length of 18- 20 mm
were used. Coronal access cavities were prepared under water cooling, using a
round bur. #15 K-file was used for the determination of working length. Root
canals were instrumented up to size F3 by using Protaper Universal files. Teeth
were then randomly divided into five groups; 17% EDTA, 1% phytic acid, 0.5%
phytic acid, 5% NaOCl and distilled water. Roots were divided longitudinally
into two parts by using diamond discs. Initial microhardness measurements at
all three levels were recorded for each sample. Final measurements following
final irrigation protocols were then recorded and the percentage reduction in microhardness
calculated. One-way variance analysis (ANOVA) and Post-hoc Tukey HSD were used
for statistical analysis.
Results: There were no statistically significant results between the groups at
the coronal and middle third of the root canal (p>0.05). However, at the
apical third, 1% phytic acid group caused a significant decrease in
microhardness (p<0.05). Reduction in microhardness caused by 0.5% phytic
acid solution was not significant (p>0.05). Results from NaOCl and distilled
water groups were statistically significant (p<0.05).
Conclusion: While there was no significant reduction in microhardness at the
coronal and middle third, 1% phytic acid solution caused a significant
reduction in microhardness at the apical third.
