“…The long-term sealing of the root canal is influenced by the sealer [31]. The VibraTHO technique encompasses indirect ultrasonic activation of the root canal sealer, heat generation by ultrasonic energy to soften the gutta-percha, and geometrically driven short warm vertical compaction of the softened gutta-percha, which gives rise to the hydrodynamic stream of the sealer [16]. Although the results of the use of a calcium silicate sealer with the VibraTHO technique appeared to improve significantly at the middle-to-coronal portion compared to the SC technique, no significant improvement was observed in the apical area (Table 2).…”

“…The tip that bound in the canal at a depth of approximately 4 mm from the orifice was assumed to "fit" the canal. After dispensation of Endoseal TCS and insertion of the prefitted master GP points, as in the SE group, the root canal filling was completed using the VibraTHO technique as described in the previous study by Cho et al [16]. The excess GP was sheared off at the orifice with the ultrasonic tip in an activated state, followed by 2-3 s of indirect ultrasonic sealer activation and heating of the GP with the activated tip.…”

“…In 2021, a novel root canal filling technique, known as ultrasonic vibration and thermohydrodynamic obturation (VibraTHO), was introduced [16]. The VibraTHO technique incorporates indirect ultrasonic sealer activation and short-range warm vertical compaction of a single GP cone.…”

This study aimed to assess the effectiveness of ultrasonic vibration and thermo-hydrodynamic obturation (VibraTHO) using two types of root canal sealers, in comparison to the single-cone (SC) technique and a calcium silicate-based root canal sealer in complex root canal anatomies. Thirty single-rooted human maxillary premolars with two canals that had a complex root canal anatomy of transverse anastomoses or ramifications were prepared and assigned to the following three experimental groups, according to the filling method: SE group, SC technique with Endoseal TCS; VE group, VibraTHO with Endoseal TCS; and VG group, VibraTHO with GuttaFlow 2. Each tooth was scanned using micro-computed tomography, and the volume percentages of the filling material were calculated. The analysis of variance was used to analyze the statistical differences between the three groups (p < 0.05). The mean volume of the filling material was higher in the VG and VE groups than that in the SE group (p < 0.05) along the apical to middle-to-coronal thirds, and significant differences were observed between each root canal area (p < 0.05), with the only exception being at the apical thirds between the VE and SE groups. The VibraTHO technique using GuttaFlow 2 can be a more effective root canal filling method for anatomically complex root canal systems than the SC technique with Endoseal TCS. On the other hand, the VibraTHO technique using Endoseal TCS has a limited effect on improving the quality of the root filling at the apical portion of anatomically complex root canal systems, compared to the SC technique with Endoseal TCS.

“…The ultra-sonic time of application during master cone placement was 2-3 sec., and excess guttapercha was cut at canal's orifice using hot instrument. (8) Fig (9) The US tip that produces optimum fitting within the 4 mm from the canal orifice and bind to the canal at the needed depth was selected. After the introduction of sealer, the master gutta-percha point was gently inserted to the working length.…”

The present study aimed to evaluate the filling quality of a bioceramic sealer with a single gutta-percha cone technique using ultrasonic sealer activation. Twenty-four single-rooted mandibular premolars were selected. Canals were instrumented and allocated into three groups randomly according to the method of ultrasonic sealer activation: group 1: single-cone with ultrasonic activation, group 2: single-cone with Vibration Thermo-hydrodynamic obturation (Vibra THO) technique, group 3: single-cone without ultrasonic activation. After setting of sealer, teeth were immersed in methylene blue dye then demineralized and cleared. Microleakage was assessed under stereomicroscope at 20x magnification.ANOVA and Bonferroni post hoc tests were used for the evaluation of dye penetration at the apical three mm of the roots. Single-cone without ultrasonic activation had the highest mean value of apical microleakage (4080.2±1132.1 μm) followed by the Vibra THO technique (2033.3±1754.3 μm) and the least results with single-cone with ultrasonic activation (1389.1±1094.8 μm) with statistically significant difference between the groups (P<0.05). In multiple comparisons, only statistical significant difference was found between single-cone without ultrasonic vibration and single-cone with ultrasonic activation. It was concluded that when using premixed bioceramic sealer with SC, ultrasonic activation is recommended to obtain better sealing ability of the canals.
