Contemporary Disinfections Methods on the Microhardness of Root Canal Dentin

Abstract

ABSTRACT Aim: The aim of this study is to compare PDT and ozone with traditional disinfection methods in terms of root canal dentin microhardness. Materials and Methods: One hundred distal roots of extracted mandibular third molars were included in this study. Root Canals were shaped with Reciproc (VDW, Munich, Germany) and VDW gold endodontic motor and were irrigated with 10ml distilled water. The samples were divided into 5 groups according to the final root canal disinfection method (n=20). Group 1 was disinfected with 2.5% sodium hypochlorite + 17% EDTA (NaE), group 2 with 2% chlorhexidine (CHX), group 3 with 170 ppm ozone gas (OZ), group 4 with photodynamic therapy (FDT). Group 5 was assigned as the control group (DS), and only distilled water was irrigated. Root canal dentin microhardness was evaluated using the Vickers test method. Data were evaluated with one-way analysis of variance at 95% confidence interval. Results: The OZ group was the group with the highest microhardness value of 53.83 and the differences were significant when compared with NaE (48.45), CHX (48.58) and DS (49.07) groups. There was a significant difference in the FDT group with 53.74 microhardness values when compared with the NaE and CHX groups. Conclusion: Within the limitations of this in vitro study, ozone or photodynamic therapy as a disinfection method may contribute to the hardness of the root canal dentin structure.

Güncel Dezenfektan Yöntemlerinin Kök Kanal Dentin Mikrosertliği Üzerine Etkisi

Abstract

ÖZ Amaç: Bu çalışmanın amacı, fotodinamik terapi ve ozon gazının kök kanal dentin sertliğine etkisinin konvansiyonel yöntemlerle karşılaştırılarak incelenmesidir. Gereç ve Yöntem: Çekilmiş yüz mandibular üçüncü molar dişin distal kökleri bu çalışmaya dahil edildi. Kök kanalları Reciproc (VDW, Münih, Almanya) ve VDW altın endodontik motor ile şekillendirildi ve 10 ml distile su ile irrige edildi. Son kök kanal dezenfeksiyon yöntemine göre örnekler 5 gruba ayrıldı (n=20). Grup 1 %2,5 sodyum hipoklorit + %17 EDTA (NaE) ile; grup 2 %2 klorheksidin (CHX) ile; grup 3 170 ppm ozon gazı ile (OZ); grup 4 fotodinamik tedavi (FDT) ile dezenfeksiyon işlemi tamamlandı. Grup 5 kontrol grubu olarak atanarak (DS) sadece distile su irrige edildi. Kök kanal dentin mikrosertliği Vickers test yöntemi ile değerlendirildi. Veriler, %95 güven aralığında tek yönlü varyans analizi ile değerlendirildi. Bulgular: OZ grubu 53.83 ile en yüksek mikrosertlik değerine sahip olan grup olup NaE (48.45), CHX (48.58) ve DS (49.07) grupları ile karşılaştırıldığında anlamlı fark bulunmuştur. 53.74 mikrosertlik değeri sahip olan FDT grubu NaE ve CHX grupları ile karşılaştırıldığında anlamlı fark bulunmuştur. Sonuç: Bu in vitro çalışmanın sınırlamaları dahilinde, dezenfeksiyon yöntemi olarak ozon veya fotodinamik tedavi, kök kanal dentin yapısının sertliğine katkıda bulunabilir.
