In the complementary preparation, all root canals were prepared by Flatsonic (Figure 1 ) coupled to the ultrasound appliance Ultrawave XS (Ultradent Products) at a frequency of 50 Hz and power of 25%. This tip was activated inside the root canal, at 4 mm to the WL, in the direction of the flattened area (buccal and lingual direction) performing 3 cycles of 30 seconds. Each cycle was performed as follows: 15 seconds in the direction of the buccal wall, with 10 seconds performed without air/water cooling and 5 seconds with air/water cooling in accordance with the manufacturer's specifications. The same procedure was performed for the lingual wall. In each ultrasound cycle, 2.5 mL of 2.5% NaOCl was used (1.25 mL before and 1.25 mL after each cycle). After use of the Flatsonic, the PDL 25/0.03 instrument was operated using a VDW.SILVER motor, with rotary motion, at 950 rpm and a torque of 2 N·cm, in accordance with the manufacturer's specifications. The instrument was introduced into the root canal up to the WL, after which brushing motions were made on the buccal and lingual walls (flattened areas in the apical third) with an amplitude of 3 mm, totaling 3 motions on each wall. The irrigation and final irrigation protocols were performed in accordance with the criteria previously described for preparations with NiTi systems.

After obtaining approval from the Institutional Ethics Committee (Registration number #CAAE: 9779617.5.0000.5416), 12 extracted 2-rooted maxillary premolars without any anomalies in the root canal system were selected. Root-end resection was performed at 90° from the long axis of the root, approximately 3 mm from the apex. After apicectomy, 3.0-mm deep cavities were prepared using an Ultrawave device (Ultrawave XS, Ultradent, South Jordan, UT, USA) with a T1F-R ultrasonic retrotip (CVD-Vale, São José dos Campos, SP, Brazil).
The teeth were divided randomly into 3 groups, and the cavities were filled with mineral trioxide aggregate (MTA) (Angelus, Londrina, PR, Brazil), Biodentine (Septodont, Saint Maur des Fosses, France) or Intermediate Restorative Material (IRM) (Dentsply DeTrey, Konstanz, Germany) by a single, previously trained and calibrated operator. The materials were mixed according to the respective manufacturer's instructions. The samples were kept in an oven at 37℃ and 95% humidity for 3 times longer than their recommended setting time.

Conventional access cavities were prepared, and the canals were explored with a size 10 K-file (Dentsply Maillefer, Ballaigues, Switzerland) until their tip became visible in the apical foramen. The working length (WL) was established 1.0 mm short of the apical foramen. The root canals were prepared with the Reciproc Blue R40 file (VDW, Munich, Germany). The instruments were driven by an electric motor (VDW Silver, Munich, Germany) in the "RECIPROC ALL" function, according to the manufacturer's instructions, up to the WL. Root canal irrigation during preparation was performed with 6 mL of 2.5% sodium hypochlorite (NaOCl) (2 mL for each third). A 30-G NaviTip needle (Ultradent Products, South Jordan, USA) was coupled to a 5 mL syringe, and placed up to 2 mm short of the WL.
A complementary preparation was performed using a Flatsonic ultrasonic tip (Helse Ultrasonic, Santa Rosa de Viterbo, Brazil) activated by an Ultrawave XS (Ultradent) appliance at a power of 25% and frequency of 50 Hz. The ultrasonic tip was activated for 3 cycles, each cycle lasting 30 seconds in the direction of each flattened region (buccal and lingual). A total of 3 mL of 2.5% NaOCl was used (1.5 mL before and 1.5 mL after each cycle) for each ultrasound cycle. Final irrigation of each sample was performed with 5 mL 2.5% NaOCl, followed by 2 mL 17% EDTA and 5 mL of distilled water.

The Irrisonic ultrasonic tip was activated in an Ultrawave XS ultrasonic device (Ultradent, South Jordan, USA) using a power of 10% and frequency of 50 Hz, according to the manufacturer's recommendation. The ultrasonic tips were positioned 2 mm short of the working length and used in in-and-out movements to avoid contact with the root canal walls. The irrigant solution was delivered into the root canals, and the ultrasonic activation was performed using three cycles of 20 seconds each, with 2.5% NaOCl in the first and third cycles, and 17% EDTA in the second cycle. A 2-mL aliquot of irrigation solution was used in each cycle, totalizing 4 mL of NaOCl and 2 mL of EDTA. The final irrigation used 5 mL of distilled water.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
