Tek kon açýlý güta perka kanal dolgu yöntemi ile diðer kanal dolgu yöntemlerinin apikal sýzdýrmazlýklarýnýn dört farklý kanal patý kullanýlarak karþýlaþtýrýlmasý

GÝRÝÞ ve AMAÇ: Araþtýrmamýzda, tekkon (ProTaper Gutta-Perka)(PTGP) olarak uygulanan açýlý gutta-perka tekniðinin apikal sýzdýrmazlýðýnýn, lateral kondensasyon ve Thermafil teknikleriyle 4 farklý kanal patý kullanýlarak boya penetrasyon ve þeffaflaþtýrma yöntemiyle karþýlaþtýrmalý olarak deðerlendirilmesi amaçlanmýþtýr.
YÖNTEM ve GEREÇLER: Araþtýrmada çekilmiþ 200 adet tek kanallý alt premolar diþ kullanýldý. Tüm diþlerin kök kanal preparasyonlarý ProTaper Ni-Ti enstrümanlarla yapýldý. 20 adet diþ negatif ve pozitif kontrol grubu olarak ayrýldý. Geri kalan 180 adet diþ 60’ar adetlik 3 ana gruba ve bunlarda kendi aralarýnda 15’er adetlik 4 alt gruba ayýrýldý. Bu 3 ana gruba lateral kondensasyon, Thermafil ve tekkon (PTGP) kanal dolgu teknikleri 4 farklý kök kanal patý (Roekoseal, AH Plus, Diaket ve Ketac-Endo) ile uygulandý. Kanal dolgularý tamamlanan bütün gruplara boya sýzýntýsý ve þeffaflaþtýrma yöntemi uygulanarak lineer ölçüm metoduyla sýzýntý miktarlarý belirlendi. Ýstatiksel analizler için ANOVA testi ile birlikte Bonferroni ve Tukey ileri düzey testleri kullanýldý (p ≤ 0.05).
BULGULAR: En fazla boya sýzýntý deðerini 2.902 ± 2.041 mm ile tekkon (PTGP) tekniði gösterirken, lateral kondensasyon 2.173 ± 1.447 mm ve en az sýzýntýyý 1.832 ± 1.009 mm ile Thermafil tekniði göstermiþtir. Lateral kondensasyon ve Thermafil teknikleri arasýndaki fark istatiksel olarak anlamlý bulunmazken, tekkon (PTGP) tekniði bu iki tekniðe göre anlamlý derecede farklý bulunmuþtur (p>0.05). Kanal dolgu patlarý içinde ise en az apikal sýzýntý deðeri Diaket ve Roekoseal kullanýlan gruplarda, en fazla sýzýntý ise Ketac-Endo kullanýlan gruplarda gözlenmiþtir. Tekkon (PTGP) kanal dolgu yöntemin sýzdýrmazlýðý, Diaket ve Roekoseal ile kullanýldýðý gruplarda diðer kanal dolgu yöntemlerinden farksýz iken, AH-Plus ve Ketac-Endo ile kullanýldýðýnda anlamlý olarak daha fazla apikal sýzýntý göstermiþtir.
TARTIÞMA ve SONUÇ: Genel anlamda tekkon(PTGP) tekniðinin, lateral kondensasyon ve Thermafil tekniðine oranla sýzdýrmazlýðýnýn yetersiz olduðu fakat birlikte kullanýldýðý kanal patlarýna göre farklýlýk göstererek bu iki tekniðe yakýn sýzdýrmazlýk saðlayabileceði sonucuna varýlmýþtýr.

The comparison of apical microleakage of single-cone tapered gutta-percha canal filling technique with the other gutta-percha canal filling techniques using with four different canal sealers

INTRODUCTION: The aim of this study is to evaluate apical sealing of single-cone tapered gutta-percha technique with lateral condensation and thermafil techniques by using 4 different canal sealers dye penetration and clearing methods comperatively.
METHODS: 200 single canal extracted mandibular premolars were used in this study. Root canal preparation of teeth were performed with ProTaper ni-ti- instruments. 20 premolars were separated as negative and positive control groups. 180 teeth were divided into 3 main groups which are consisted of 60 teeth and these groups were divided into 4 sub groups which are consisted of 15. Lateral condensation, thermafil and single cone techniques were applied with 4 different root canal sealer. After filling all the root canals, dye leakage and clearing methods were applied to all groups and by using lineer measurement method the amount of leakage were identified. ANOVA test were used for statistical analysis.
RESULTS: The maximum dye leakage was in the single cone technique 2.902=2.041 mm, in lateral condensation 2.173=1.477mm and the minimum value was 1.832=1.009mm in Thermafil technique. The difference between lateral condensation and thermafil techniques was not statistically different but single cone technique was found significantly different. The minimum apical leakage value of all root canal sealers was found in groups which diaket and roekoseal were used, the maximum leakage was in ketac-endo group. The unleakage of single cone root canal filling technique was not different than other techniques when diaket and reakoseal were used but the apical leakage was significantly higher when AH plus and keta-endo were used.
DISCUSSION AND CONCLUSION: As a result single cone root canal filling technique is insufficient when compared to lateral condensation and Thermafil techniques about apical leakage; but can show a difference based on the canal sealers It was used with and can provide similar unleakage like those two techniques.
