Objective: The aim of this study is to evaluate the effect of different filling methods on canal filling quality in resin primary molar teeth prepared with two different preparation techniques. Material and Methods: For the study, 60 maxillary primary second molar teeth obtained from resin block were used. Root canals were prepared using a manual #K-file (n=30) and a VDW RotateTM System (n=30) rotary instrument. Each group was divided into 3 subgroups according to the filling technique used (n=10): Calci-Paste® syringe (control group); Calci-Paste® syringe and Uc-One® (ultrasonic activation); Calci-Paste® syringe and Eddy® (sonic activation). The quality of the canal filling (under filled, optimal filled, overfilled) and the presence/absence of voids were assessed using cone beam computed tomography. SPSS (Statistical Package for Social Science, IBM SPSS®, version 26, Chicago, USA) program was used for statistical analysis. Results: There was no significant difference between the different preparation and filling techniques in terms of filling volume and length, In the study, voids were detected in all three filling methods, but the highest void filling was found in the Calci-Paste® syringe +ultrasonic activation group (48%). The manual preparation and syringe group had the most optimally filled teeth but there was no significant difference between the groups (For preparation methods p=0.573; for filling methods p=0.976). Conclusion: In this study, it was found that sonic and ultrasonic systems did not improve the quality of root canal filling in resin primary molars and ultrasonic activation caused more voids.

Amaç: Bu çalışmanın amacı, iki farklı preparasyon tekniği ile hazırlanan rezin süt molar dişlerde farklı dolum yöntemlerinin kanal dolum kalitesi üzerine etkisini değerlendirmektir. Gereç ve Yöntemler: Çalışmada rezin bloktan elde edilmiş 60 adet maksiller süt 2. Molar diş kullanıldı. Kök kanallarının preparasyonu manuel #K-tipi eğe (n=30) ve VDW RotateTM System (n=30) döner alet kullanılarak yapıldı. Her grup kullanılan dolum tekniğine göre 3 alt gruba ayrıldı (n=10): Calci-Paste® enjektör (kontrol grubu); Calci-Paste® enjektör ve Uc-One® (ultrasonik aktivasyon); Calci-Paste® enjektör ve Eddy® (sonik aktivasyon). Kanal dolumunun kalitesi (eksik dolum, optimal dolum, taşkın dolum) ve boşluk varlığı/yokluğu konik ışınlı bilgisayarlı tomografi kullanılarak değerlendirildi. İstatistiksel analiz için SPSS (Statistical Package for Social Science, IBM SPSS®, version 26, Chicago, ABD) programı kullanıldı. Bulgular: Farklı preparasyon ve dolum teknikleri arasında dolum hacmi ve uzunluğu açısından anlamlı bir fark bulunmamıştır (p>0,05). Bu çalışmada, her üç dolum yönteminde boşluk saptandı ancak en fazla boşluklu dolum Calci-Paste®enjektör+ultrasonik aktivasyon (%48) grubunda bulundu. Manuel preparasyon ve enjektör grubu en optimal doluma sahipti ancak gruplar arasında anlamlı bir fark bulunmadı (preparasyon yöntemleri için p=0,573; dolgu yöntemleri için p=0,976). Sonuç: Bu çalışmada, rezin süt molar dişlerde sonik ve ultrasonik sistemlerin kök kanal dolumunun kalitesini artırmadığı ve ultrasonik sistemlerin daha fazla boşluğa neden olduğu bulunmuştur.
