GÝRÝÞ ve AMAÇ: Bu çalýþmanýn amacý, endodontik tedavilerde kullanýlan çeþitli þelasyon ajanlarýnýn kök dentinin mineral içeriðinde yarattýðý deðiþiklikleri deðerlendirmektir.
YÖNTEM ve GEREÇLER: EDTA, NaOCl, fitik asit ve sitrik asitin (CA) kök dentini mineral içeriði üzerindeki etkileri, enerji daðýtýcý x-ýþýný spektroskopisi (EDX) kullanýlarak analiz edilmiþtir. 15 adet çekilmiþ insan maksiller ön diþinden 30 adet dentin örneði hazýrlanmýþtýr. Örnekler 5 deney grubuna ayrýlmýþtýr. Deney gruplarý, distile su (kontrol grubu), NaOCl (%5), EDTA (%17), fitik asit (%1) ve sitrik asit (%10) solüsyonlarýnda bekletildikten sonra kök dentininde bulunan kalsiyum (Ca) ve fosfor (P) seviyeleri ölçülmüþtür.
BULGULAR: Sonuçlarýn istatistiksel analizinde, tek yönlü ANOVA ve Tukey testleri kullanýlmýþtýr. CA ve fitik asit grubunun Ca düzeyleri kontrol, NaOCl ve EDTA gruplarýndan anlamlý derecede düþük bulunmuþtur (p<0.05). CA ve fitik asit grubunun P düzeyleri kontrol, NaOCl ve EDTA gruplarýndan anlamlý düzeyde yüksek bulunmuþtur (p<0.05). CA ve fitik asit grubunun Ca/P düzeyleri kontrol, NaOCl ve EDTA gruplarýndan anlamlý derecede düþük bulunmuþtur (p<0.05).
TARTIÞMA ve SONUÇ: Fitik asit ve sitrik asitin diðer irrigasyon ajanlarýna göre kök dentininden daha fazla kalsiyum uzaklaþtýrdýðý sonucuna varýlmýþtýr. Bu, kök dentini yapýsýnýn pürüzlülük, geçirgenlik ve mikrosertlik gibi özelliklerini etkileyecektir. Bu ajanlar kanal tedavisi sýrasýnda dikkatli kullanýlmalýdýr.

INTRODUCTION: The aim of this study is to evaluate the changes in the mineral content of root dentin caused by various chelating agents used in endodontic treatments.
METHODS: The effects of EDTA, NaOCl, phytic acid and citric acid (CA) on root dentin mineral content were analyzed using energy dispersive x-ray spectroscopy (EDX). 30 dentin samples were prepared from 15 extracted human maxillary anterior teeth. The samples were divided into 5 experimental groups. Calcium (Ca) and phosphorus (P) found in root dentin after the experimental groups were kept in distilled water (control group), NaOCl (5%), EDTA (17%), phytic acid (1%) and citric acid (10%) solutions. levels were measured.
RESULTS: One-way ANOVA and Tukey tests were used in the statistical analysis of the results. The Ca levels of the CA and phytic acid groups were significantly lower than the control, NaOCl and EDTA groups (p<0.05). The P levels of the CA and phytic acid groups were significantly higher than the control, NaOCl and EDTA groups (p<0.05). The Ca/P levels of the CA and phytic acid groups were significantly lower than the control, NaOCl and EDTA groups (p<0.05).
DISCUSSION AND CONCLUSION: It was concluded that phytic acid and citric acid remove more calcium from root dentin than other irrigation agents. This will affect the properties of root dentin structure such as roughness, permeability and microhardness. These agents should be used with caution during root canal treatment.
