Farklı Yıkama Tekniklerinin Smear Tabakasını Uzaklaştırma Etkinlikleri

Amaç: Bu çalışmanın amacı, farklı yıkama tekniklerinin kök kanallarından smear tabakasını uzaklaştırma etkinliklerini karşılaştırmaktır. Yöntem: Madde kaybı bulunmayan periodontal nedenlerle çekilmiş 30 adet tek kök ve tek kanallı insan alt küçük azı dişi her grupta 10 adet diş olacak şekilde 3 deney grubuna ayrıldı. Tüm deney gruplarında kök kanallarının genişletme ve şekillendirme işlemi ProTaper® F4 numaralı alete dek gerçekleştirildi. 1. grupta 27 gauge kalınlığında dental iğne ucu korono-apikal yönde hareket ettirilerek, 2. grupta 31 gauge kalınlığında Ultradent NaviTip® Double Sideport yıkama ucu ve 3. grupta ise EndoVac yıkama cihazı hem kök kanal şekillendirilmesi sırasında hem de son yıkama sırasında kullanıldı. Son yıkamada smear tabakasının uzaklaştırılması amacıyla sırasıyla 3 ml %5 EDTA, 3 ml %2,5 NaOCl ve son olarak 3 ml distile su kullanıldı. Yıkama sistemlerinin smear tabakasını uzaklaştırma etkinlikleri taramalı elektron mikroskobu ile değerlendirdi. Verilerin istatistiksel analizinde %95 güven aralığında Kruskal-Wallis ve Mann-Whitney U testleri kullanıldı. Bulgular: Tüm deney gruplarında smear tabakasının koronal 1/3'lük kısımda apikal 1/3'lük bölgeye kıyasla daha iyi uzaklaştırıldığı gözlendi. Ancak, sistemlerin tüm bölgelerde smear tabakasını uzaklaştırma etkinlikleri arasında istatistiksel farklılık saptanmadı. Sonuç: Smear tabakasının uzaklaştırılmasında EndoVac sistemi konvansiyonel yıkama teknikleri ile benzer etkinlik göstermiştir.

Smear Layer Removal Efficacy Of Different Irrigation Techniques

OBJECTİVES: To compare the cleaning efficacy of 3 root canal irrigation techniques as well as their effectiveness in removing smear layer from root canal walls. METHODS: Thirty permanent mandibular premolars were divided into 3 groups of 10 teeth each. Teeth were instrumented with ProTaper rotary system up to F4. In group I, the teeth were irrigated by conventional irrigation using 27-gauge irrigation-needle. In group II, irrigation was done using 31-gauge NaviTip Double Sideported-needle. In group III, irrigation was performed with EndoVac irrigation system. Final irrigation was performed using 3 ml 2.5% sodium hypochlorite followed by 3 ml 5% EDTA and a final rinse with 3 ml distilled water. Scanning electron microscope evaluation was done for assessment of smear layer removal in the coronal, middle, and apical thirds. Data were analyzed using Kruskal-Wallis and Mann-Whitney U tests for significance at P <= .05. RESULTS: The removal of smear layer from the coronal third of root canals was significantly better than apical and middle thirds (p<0.05). No significant difference was observed between the procedures according to smear layer removal ability. CONCLUSİON: EndoVac system showed no betterment over conventional irrigation procedures.
