“…In the injectable group, after PUI, the highest performance was related to XP-endo Finisher (45.8%), EA (20%), and SNI (8.3%), respectively. Therefore, in line with the previous studies [ 29 , 33 , 36 , 37 ], it was concluded that PUI possesses a great aptitude in clearing remote areas.…”

The present study aimed to investigate the efficiency of passive ultrasonic irrigation (PUI), EndoActivator (EA), standard needle irrigation (SNI), and XP-endo Finisher files in removing pure calcium hydroxide (pCH) and injectable CH from in vitro root resorption cavities. Using a rotary system, the root canals of 116 extracted single rooted teeth were prepared. Imitated internal resorption cavities were then created in root halves. The specimens were divided into two groups according to the form of CH (n = 58): (I) pCH; (II) injectable CH. The teeth of each group were randomly divided into six subgroups: negative control (n = 5), positive control (n = 5), PUI (n = 12), XP-endo Finisher (n = 12), EA (n = 12), and SNI (n = 12). The root canals were irrigated using NaOCl and EDTA and split longitudinally, and both halves were evaluated with a stereomicroscope. Kruskal–Wallis and Mann–Whitney U tests were used to analyze data. The present results revealed that PUI completely removed pCH in 79% and injectable CH in 70.8% of the internal resorption cavities which was significantly higher than other methods (p<0.05). There was no statically significant difference between different forms of CH in terms of CH removal (p=0.918). The PUI technique was observed as the most efficient method of P-CH and injectable CH removal from a replicated internal resorption cavity. Finally, according to the findings, different forms of CH were comparable in terms of CH removal.

“…Different methodologies have been used to assess the amount of Ca(OH) 2 remaining 22,31,32 . In the present study, the specimens were longitudinally split, and the percentage of residual Ca(OH) 2 was calculated from images obtained under magnification of the entire area desired at stereomicroscopy.…”

Objective: this study aimed to assess the effectiveness of Passive Ultrasonic Irrigation (PUI) with different solutions for calcium hydroxide (Ca(OH) 2 ) removal. Materials and method: forty-eight single-rooted mandibular premolars were prepared and filled with Ca(OH) 2 . After 15 days, the specimens were randomly divided into four groups according to the method of removal of the intracanal medication (n=12). In Group 1, Ca(OH) 2 removal was performed through conventional irrigation with 2.5% NaOCl and 17% EDTA combined with the use of the 'master apical file' at working length. Groups 2 and 3 were treated in the same manner as Group 1, following the PUI with 2.5% NaOCl and 17% EDTA, and 2.5% NaOCl and 10% citric acid, respectively. Group 4 served as a control group and received no intracanal medication. The roots were longitudinally grooved and split in two halves. The half with the higher remaining amount was analyzed with a stereomicroscope, and the percentage of surface area covered by the remaining Ca(OH) 2 in relation to the total surface area and the surface area of each third of the root canal was calculated. The results were statistically analyzed with the Kruskal-Wallis Test and Mann-Whitney Test. Null hypothesis was set as 5%. Results: none of the groups tested showed similarity to the control group (P < 0.05).However, no statistical difference was observed between the removal techniques of Ca(OH) 2 from root canals. Conclusions: neither syringe irrigation nor the combination of syringe irrigation with PUI were effective methods for removing Ca(OH) 2 from the root canals.

“…A substância Hidróxido de Cálcio (Ca(OH) 2 ) é amplamente utilizada no tratamento endodôntico como medicação intracanal. Tem como características a ação antimicrobiana, a degradação de restos teciduais, a inibição da reabsorção radicular e a indução de reparação de tecidos duros (4). No entanto, o Ca(OH) 2 é difícil de ser removido, uma vez que o material se adere às paredes do conduto radicular e interfere na adaptação do material obturador, causando futuras infiltrações que influenciarão negativamente o prognóstico do tratamento (5,6).…”

Objetivo: Avaliar a eficácia da remoção de Ca (OH)2 do canal radicular, comparando o uso de limas manuais, Easy Clean e irrigação ultrassônica passiva (IUP). Método: Trinta dentes incisivos bovinos foram utilizados neste estudo. Os canais radiculares foram preparados e as amostras foram divididas aleatoriamente em 3 grupos de acordo com a técnica utilizada para a remoção do Ca(OH)2 (n = 10): G1: limas manuais; G2: lima Easy Clean; G3: IUP. Após quinze dias, os espécimes foram seccionados e processados para observação dos terços médio e apical utilizando microscopia eletrônica de varredura (MEV). Um avaliador cego e calibrado atribuiu escores a cada espécime. Os dados obtidos foram submetidos ao teste de Kruskal-Wallys, seguido do teste de Dunn. Resultados: Não houve diferença significativa na remoção do Ca(OH)2 entre a lima manual e a Easy Clean e entre Easy Clean e IUP. A técnica de IUP removeu significativamente mais Ca(OH)2 quando comparado com o grupo lima manual. Nenhuma das técnicas testadas removeu completamente o Ca(OH)2 das paredes do canal radicular. Conclusão: Independentemente da técnica utilizada, nenhum dos protocolos testados removeu completamente o Ca(OH)2 do canal radicular. Entretanto, a irrigação ultrassônica passiva foi mais eficaz do que o grupo das limas manuais.
