İrrigasyon Solüsyonlarının Kök Kanalından Kalsiyum Hidroksit Uzaklaştırma Etkinliğinin Değerlendirilmesi

Amaç: Bu çalışmada geleneksel şırınga irrigasyonunda kullanılan çeşitli irrigasyon solüsyonlarının kök kanalının apikal kısmında hazırlanan bir oluktan kalsiyum hidroksit medikamentini uzaklaştırma etkinlikleri değerlendirilmiştir. Yöntemler: Toplam 100 adet tek köklü insan dişinin kronları uzaklaştırılıp, kök uzunlukları standardize edildi. Kökler uzunlamasına ikiye ayrıldı her iki yarımın apikal 1/3’lük kısmına standart oluklar açıldı. Ca(OH)2 95 örneğin kök kanallarına ve oluklara yerleştirildi, bir hafta bekletildi. Beş örnek pozitif kontrol grubu olarak ayrıldı. Kalan örnekler irrigasyon ajanlarına göre çalışma gruplarına rastgele ayrılarak (n=18); NaOCl (%5,25), EDTA (%17), etanol (%70), GA(%10) veya SA (%10) ile irrigasyon iğnesi kullanılarak yıkandı. Her örnekteki oluklar 20X büyütme altında stereomikroskop ile incelendi, Van der Sluis sınıflamasına göre skorlandırıldı. Elde edilen veriler her grubun skor ortalamasını karşılaştırmak için Kruskal-Wallis H testi ile analiz edildi. Bulgular: En düşük skor EDTA grubunda saptanırken, EDTA’nın Ca(OH)2 uzaklaştırma becerisi NaOCl, SA ve etanol ile benzer bulunmuştur (p > .05). En yüksek skorun saptandığı GA grubunda Ca(OH)2 uzaklaştırma skorları EDTA ve SA’dan anlamlı oranda yüksektir (p < .05). Sonuçlar: Test edilen solüsyonların iğne irrigasyonunda kullanılmaları sonucu hiçbiri Ca(OH)2 medikamentinin tamamen uzaklaştırılmasında başarılı olmamıştır. En iyi skorlar EDTA ve SA solüsyonlarında tespit edilirken en yüksek skor GA grubunda tespit edildi.
