“…In the present study, the heat of the plugger tip was not measured, but the increase in the external temperature was dissipated, meaning that it was actually transmitted to the patient, who sometimes feels that heat. Similar to the study of Venturi et al [28], the measurements were performed in the air, unlike Dimopoulos et al [21], who used a polytetrafluoroethylene (PTFE) cylinder. According to Nikolaev et al [29], the current devices used to perform the continuous heat wave technique are completely safe and effective.…”

“…To achieve a high amount of gutta-percha, filling techniques have been developed to achieve this purpose. When the apical part of the canal is filled with the Buchanan continuous wave technique at −4 mm, the gutta-percha is not thermoplasticised in the last few millimetres, since the gutta-percha is a very poor conductor of heat [20][21][22]. For that reason, in this study, canals have been filled to different depths with three different systems, and the emitted heat has been observed.…”

The aim of this study was to assess temperature changes with different continuous wave obturation systems when downpacking to 2 mm and 4 mm from the apical foramen in an open system not simulating the surrounding biological structures at body temperature. Sixty single-rooted teeth were divided into three groups: (A) Dia-Duo® (DiaDent Group International, Cheongju-si, Korea), (B) Elements Free® (Kerr Corporation, Orange, CA, USA) and (C) Calamus® (Dentsply Sirona, Ballaigues, Switzerland). The root canals were instrumented with Protaper Gold (Dentsply Sirona, Ballaigues, Switzerland) to size F2 (25.08). The root canals were filled by a continuous wave using an AH Plus® sealer (Dentsply Sirona). Temperatures during the obturation procedure were measured by a thermal imaging camera (Testo 875-1®) perpendicular to a vice where the teeth were held at −2 mm and −4 mm from the apical foramen. Comparisons were made by applying Student’s t-test and ANOVA (p = 0.05). The continuous wave technique at −2 mm with the Dia-Duo system® emitted average temperatures of 37.3 °C, Elements Free® emitted 39.85 °C and Calamus® emitted 40.16 °C. At −4 mm, the Dia-Duo system® emitted average temperatures of 34.81 °C, Elements Free® emitted 33.73 °C and Calamus® emitted 32.91 °C. There were significant differences between continuous waves at −2 mm and at −4 mm (p < 0.05). Dia-Duo® was the only system that did not present significant differences between the two lengths (p = 0.197). Regarding the heat emitted, the best system was Elements Free®, since, at −2 mm, it emitted the highest temperature without going above 47 °C. The Dia-Duo® system had lower temperatures. It could be concluded that not all systems transmit the same temperature to the apex and, therefore, to the periapical tissues. The surrounding conditions, such as temperature and humidity, have not been considered in this study.
