Aim: The current study aimed to evaluate the effectiveness of QMix and EDTA solutions in removing Ca(OH) 2 from root canals. Materials and Methods:Forty-eight mandibular premolar teeth were instrumented by ProTaper Universal instruments. All of the teeth were then fixed in modified Eppendorf vials using a silicone impression material. After the removal of the specimens from the Eppendorf vials the roots were split into two halves longitudinally and standard longitudinal grooves were then created on the dentinal walls at a level of 3 mm below the cementoenamel junction and 3 mm above from the apex of the roots. The Ca(OH) 2 was placed into the grooves and the specimens were then remounted into the silicone impression material. Six groups were formed: Needle-EDTA, Needle-QMix, Ultrasonic-EDTA, Ultrasonic-QMix, Sonic-EDTA and Sonic-QMix. The root halves were separated and digital images of artificially created grooves were obtained with a stereomicroscope at a 25x magnification. The Ca(OH) 2 left on the artificially created grooves were scored using a 4-graded scoring system and the data were statistically analyzed.Results: Needle QMix group removed more Ca(OH) 2 than with the EDTA group at the apical part of the root canal (P < 0.083). Conclusions:When the irrigation was performed by a conventional needle, the QMix solution had better efficiency than EDTA in removing Ca(OH) 2 from the apical part of the root canal. In clinical practice, the QMix solution can be used effectively for the removal of Ca (OH) 2.

“…It can be suggested that the influence of CH in the penetration of AH Plus could be more apparent in middle third, since the apical third has less dentinal tubules The lower sealer penetration in the apical third is also attributed to the ineffective delivery of irrigants and the reduced effectiveness of smear layer removal techniques in the apical region. CH removal is more difficult in the apical third; despite this, it interestingly did not have a role in the tubular penetration of both sealers in the 3-mm level segments (4,21).…”

“…Despite various proposed techniques, no technique thoroughly removes the CH dressing (4,21). The conventional syringe irrigation was used to remove the CH dressing before obturation procedures because this method does not require special devices, since the syringe is already used in root canal treatment.…”

Objective: The aim of this study was to evaluate the effect of a calcium hydroxide (CH) dressing on the tubular penetration of two endodontic sealers, AH Plus (Dentsply Maillefer, Ballaigues, Switzerland) and MTA Fillapex (Angelus, Londrina, Brazil). Methods: Seventy-two mandibular premolars with a single root canal were prepared with ProFile.04 rotary instruments (Dentsply Maillefer) and divided into four groups. In two groups, an intracanal CH dressing was placed for 15 days. The obturations were performed with lateral condensation of gutta-percha in combination with one of the tested sealers. The roots were transversely sectioned at the apical and middle levels. The percentage of sealer penetration in the root canal walls and the percentage of impregnated dentin area in the transverse sections were obtained using confocal laser scanning microscopy. Statistical analysis was performed using one-way analysis of variance (ANOVA) and Games-Howell test. Results: The CH dressing reduced the mean value of tubular penetration in the middle third of teeth obturated with AH Plus (P<0.01), whereas no difference was observed at the apical sections for both sealers. Conclusion:The CH dressing did not interfere with the apical penetration of both tested sealers, however, decreased the tubular penetration in the middle third of the AH Plus root canal fillings. Overall, MTA Fillapex presented higher tubular penetration than AH Plus obturations. Keywords: Calcium hydroxide, confocal laser scanning microscopy, epoxy resin-based root canal sealer, mineral trioxide aggregate-based sealer

“…Ancak bu sonuçlardan farklı olarak, Çapar ve ark. 22 EndoVac'ın Ca(OH) 2 uzaklaştırmada yetersiz olduğunu belirtmişler ve bunun sebebi olarak kanal içine yerleştirilen mikrokanüller üzerindeki deliklerin tıkan-masını göstermişlerdir. Bu çalışmada da aynı problem gözlenmiş olmasına rağmen, bu durumun elde edilen sonuçları etkilemediği görülmüştür.…”

ÖZET Amaç: Bu çalışmanın amacı, EndoVac, pasif ultrasonik ve manuel aktivasyonun kök kanallarından Ca(OH)2'in uzaklaştırılmasındaki etkinliğinin değerlendirilmesidir. Gereç ve Yöntem: Toplamda elli beş adet çekim sebebi bilinmeyen insan üst molar dişin palatinal kökü kullanılmıştır. Şekillendirme apikal çap 0,45 mm olacak şekilde step-back tekniği ile yapılmıştır. Radyoopak Ca(OH) 2 patı yerleştirilen örnekler 37 o C ve %100 nemli ortamda 1 hafta süreyle saklanmıştır. Örnekler rastlantısal olarak Ca(OH) 2 'in uzaklaştırılma tekniğine göre üç gruba (n=15) ayrılmıştır. Grup 1'de MAF (apikal şekillendirmede kullanılan son eğe) olarak belirlenen #45 numara K-tipi eğe ile manuel olarak yıkama solüsyonunun aktive edilmiştir. Grup 2'de pasif ultrasonik sistem (EMS, Nyon, Switzerland) ucuna takılan #25 spreader yardımıyla aktive edilmiştir. Grup 3'te EndoVac ile yıkama yapılmıştır. Negatif kontrol grubundaki (n=5) örneklere Ca(OH) 2 yerleştirilmemiş olup, pozitif kontrol grubunda (n=5) kanal içi medikament uygulanmış ancak herhangi bir uzaklaştırma işlemi yapıl-mamıştır. Örneklerden deneyler öncesi ve sonrasında alınan radyografilerin dijital görüntüleri ImageJ Software programı kullanılarak kuronal, orta ve apikal bölgelere ayrılmıştır. Kalan Ca(OH) 2 miktarı yüzde cinsinden değerlendirilmiştir. Verilerin istatistiksel değerlendirilmesinde Kruskal Wallis ve Dunn's çoklu karşılaştırma testi kullanılmıştır. Sonuçlar, anlamlılık p<0,05 düzeyinde değerlendirilmiştir. Bulgular: Deney gruplarından bağımsız olarak, kalan Ca(OH) 2 miktarı yüzdesi apikalde, kuronal ve orta bölgeye göre istatistiksel olarak anlamlı derecede daha yüksek bulunmuştur (p=0,0001). Apikalde kalan Ca(OH) 2 miktarı yüzdesi açısın-dan gruplar arasında istatistiksel olarak anlamlı farklılık gö-zlenmiştir (p=0,045). Apikalde manuel grupta kalan Ca(OH) 2 miktarı yüzdesi PUI kullanılan gruba göre istatistiksel olarak anlamlı şekilde daha yüksek bulunmuştur (p<0,05). Sonuçlar: Yıkama ve aktivasyon tekniklerinin hiçbiri Ca(OH) 2 'i tamamen uzaklaştıramamıştır. Apikal bölgede, EndoVac ve pasif ultrasonik yıkama etkili şekilde Ca(OH) 2 uzaklaştırıl-masını sağlamıştır. Anahtar Kelimeler: EndoVac, pasif ultrasonik yıkama, manuel aktivasyon, Ca(OH) 2 uzaklaştırılması SUMMARY Aim: The aim of this study is to compare the efficacy of EndoVac, ultrasonic and manual agitation techniques on the removal of calcium hydroxide from root canals. Materials and Methods: Fifty five palatal roots of maxillary molars were used. The roots were prepared to size #45 with step-back technique. Then, root canals were filled with a radiopaque Ca (OH) 2 paste by using lentulo spiral. The samples were stored 100% humidity and at 37 o C for 1 week. For the removing of calcium hydroxide from root canals 3 different irrigation techniques were used. In group 1 (n=15) K-files with the same size of master apical file (MAF) was used with ÖZGÜN ARAŞTIRMA
