Efficacy of ultrasonic vibration in warm gutta-percha vertical compaction.
TL;DR: Investigating whether vertical compaction of warm gutta-percha used with ultrasonic vibrations performs better compared to the traditional one produced a similar level of sealing as the traditional method.
Abstract: AIM: Vertical compaction of warm gutta-percha is a methodology to seal root canals and it might be associated with ultrasonic vibration. The aim of this paper was to determine whether vertical compaction of warm gutta-percha used with ultrasonic vibrations performs better compared to the traditional one. METHODS: Twenty-four single-rooted teeth were endodontically treated and randomly divided into two groups: in the first group (G1), teeth were filled using vertical compaction, while in the other (G2), vertical compaction was used with ultrasonic vibration. A microleakage test was performed after 24 h and 30 days from root canal sealing. RESULTS: After 24 hours, microleakage was similar in both groups (0.013 µL/min; SD 0.008); after 30 days, it was 0.006 µL/min (SD 0.004) in G1 and 0.004 µL/min (SD 0.003) in G2 (P>0.05). CONCLUSION: Under these experimental conditions, ultrasonic vibration used with vertical compaction produced a similar level of sealing as the traditional method.

TL;DR: The aim of this study is to show a thermoplastic technique of gutta-percha single-cones through a developed ultrasonic insert and it can be concluded that the obturation E N D O D O N T IA is shown.
Abstract: Single-cones gutta-percha obturation techniques have been chosen because of their simplicity, the cones adaptation to the preparation and due to their clinical and scientific proved performance in the last years. However, the cement large thickness surrounding the cones and voids might have negative impacts and may limit the use of this technique. The aim of this study is to show a thermoplastic technique of gutta-percha single-cones through a developed ultrasonic insert. Three patients were selected with highly complex clinical obturation circumstances: (1) teeth with C-shaped canal, (2) canal with internal root resorption; (3) simultaneous desobturation of middle and cervical thirds for cementation of intraradicular retainer. In all cases the preparation was performed with Wave One Gold reciprocating files (Dentsply Sirona) and the gutta-percha cones of choice were conicity 0.06 taken to the canal with AH Plus cement (Dentsply). Then they were thermoplasticized through the ultrasonic insert ObtPrep (Trinks, São Paulo, Brazil) by the technique described. In clinical cases 1 and 2, obturation of the three-thirds root was performed. In case 3, only the apical third was obturated and in the sequence cementation of Reforpost 1 glass fiber (Angelus, Londrina / PR). In all cases, simultaneous coronary shielding was performed with Opus bulk fill resin (FGM, Santa Catarina, Brazil). It can be concluded that the obturation E N D O D O N T IA
