EFFECT OF LENTULO SPIRAL USAGE AT DIFFERENT SPEEDS ON APICAL EXTRUSION OF CALCIUM HYDROXIDE

Abstract

Aim: The aim of this study was to evaluate the apical extrusion of calcium hydroxide [Ca(OH)₂] paste, which placed into the root canal with lentulo usage at different speeds and a hand file.

Material and Methods: 40 maxillary central incisors were used. Root canals were enlarged up to 40.06 Revo-S size. At each instrument change, root canal was irrigated with 2.5 mL of 5.25% NaOCl. Final irrigation was performed with 5 mL of 17% EDTA, 5 mL of 5.25% NaOCl, and 5 mL of saline; then, dried with paper-points. Each teeth were placed in the plastic tubes, and the tubes were covered with aluminium foil. Ca(OH)₂ powder and distilled water were mixed at a ratio of 1:1.5. Specimens were divided into 4 groups according to Ca(OH)₂ placement method (n=10): G1: #30 Lentulo spiral at 20000 rpm, G2: #30 Lentulo spiral at 10000 rpm, G3: #30 Lentulo spiral at 5000 rpm, G4: #40 K-Flexofile. Lentulo was used 2 mm short of the working length, and K-Flexofile at the working length. The apices of the specimens were inspected with a dental loop, and situation was scored. Data were subjected to statistical analysis using Chi-square test (α=0.05).

Results: Minimum extrusion was seen in Group 3 and 4, and maximum was in Group 1. However, there was no significant difference among the groups (P > 0.05).

Conclusions: Lentulo should be used with lower speeds in clinical practice to prevent extrusion. Ca(OH)₂ placement with K-Flexofile and lentulo spiral at 5000 rpm can be considered safe.

FARKLI HIZLARDA LENTÜLO SPİRAL KULLANIMININ KALSİYUM HİDROKSİTİN APİKAL EKSTRÜZYONU ÜZERİNE ETKİSİ
ÖZ

Amaç: Bu çalışmanın amacı, bir el eğesi ve farklı hızlarda lentülo kullanımı ile kanala yerleştirilen kalsiyum hidroksit [Ca(OH)₂] patının apikal ekstrüzyonunun değerlendirilmesiydi.

Gereç ve Yöntem: 40 adet maksiller santral keserler kullanıldı. Kök kanalları 40.06 Revo-S boyutuna kadar genişletildi. Her enstrüman değişiminde kök kanalı 2.5 mL %5.25’lik NaOCl ile irrige edildi. Final irrigasyonu 5 mL %17’lik EDTA, 5 mL %5.25’lik NaOCl ve 5 mL serum fizyolojik ile yapıldı; ardından kağıt konlar ile kurutuldu. Her bir diş plastik tüplere yerleştirildi ve tüpler alüminyum folyo ile sarıldı. Ca(OH)₂ve distile su 1:1.5 oranında karıştırıldı. Ca(OH)₂yerleştirme yöntemine göre dişler 4 gruba ayrıldı (n=10): Birinci, ikinci ve üçüncü gruplar 30 numara Lentülo ile sırasıyla 20000,10000 ve 5000 tur/dk da çalışılarak dolduruldu. Dördüncü grupta ise #40 K-Flexofile kullanıldı. Lentülo çalışma boyundan 2 mm kısa, Flexofile ise çalışma boyunda kullanıldı. Örneklerin apeksleri dental loop ile gözlendi ve durum skorlandı. Ki-kare testi kullanılarak veriler istatistiksel analize tabi tutuldu (α=0.05).

Bulgular: Minimum ekstrüzyon Grup 3 ve 4’te, maksimum taşma Grup 1’de gözlendi. Ancak, Gruplar arasında anlamlı farklılık yoktu (P > 0.05).

Sonuç: Klinik pratikte ekstrüzyondan korunmak için lentülo daha düşük hızlarda kullanılmalıdır. K-Flexofile ve 5000 rpm’de lentulo spiral ile Ca(OH)₂yerleştirilmesi güvenli olarak kabul edilebilir.
