Objective: The purpose of this article is to describe a new file featuring a unique design created for both the sonic activation of irrigants during cleaning and measuring the apical diameter. Materials and methods: To assess the effectiveness of Sonic-Tips, a MicroCTscan was performed on an upper premolar root with lateral canals. After a chemio-mechanical (cleaning and shaping process) preparation of the root canal, the same root canal was irrigated twice with a radiopaque solution. The first irrigation was done by injecting the radiopaque solution passively in the root canal through a small gauge needle, 2 mm from working length. The second irrigation again was done by delivering the radiopaque solution passively in the root canal through a small gauge needle, 2 mm from working length, but in the latter case a Sonic-Tip number 20 was activated. After each cleaning (irrigation) the root was observed under MicroCT scan. Results: The results demonstrate how Sonic-Tips enabled flushing and made it possible for the irrigant to penetrate into lateral canals. Discussion and conclusions: Cleaning, shaping and three-dimensional obturation are the three main phases of the endodontic treatement. The goal of proper cleaning of a complex root canal is not easily achieved. From previous studies, it is clearly evident how "Sonic and Ultrasonic activation of irrigants" plays a strategic role in the cleaning of a well-shaped complex root canal. Another key stage of the endodontic treatment is the "three-dimensional filling" of root canals with thermoplastic guttapercha cones. Before the filling phase, it is essential to know the accurate apical diameter of the canal, in order to choose the suitable filling material (gutta percha points, Thermafil obturators or heat carriers), followed by applying optimal condensation pressure in order to prevent overfilling.

Abstract

Objective: The purpose of this article is to describe a new file featuring a unique design created for both the sonic activation of irrigants during cleaning and measuring the apical diameter. Materials and methods: To assess the effectiveness of Sonic-Tips, a MicroCTscan was performed on an upper premolar root with lateral canals. After a chemio-mechanical (cleaning and shaping process) preparation of the root canal, the same root canal was irrigated twice with a radiopaque solution. The first irrigation was done by injecting the radiopaque solution passively in the root canal through a small gauge needle, 2 mm from working length. The second irrigation again was done by delivering the radiopaque solution passively in the root canal through a small gauge needle, 2 mm from working length, but in the latter case a Sonic-Tip number 20 was activated. After each cleaning (irrigation) the root was observed under MicroCT scan. Results: The results demonstrate how Sonic-Tips enabled flushing and made it possible for the irrigant to penetrate into lateral canals. Discussion and conclusions: Cleaning, shaping and three-dimensional obturation are the three main phases of the endodontic treatement. The goal of proper cleaning of a complex root canal is not easily achieved. From previous studies, it is clearly evident how "Sonic and Ultrasonic activation of irrigants" plays a strategic role in the cleaning of a well-shaped complex root canal. Another key stage of the endodontic treatment is the "three-dimensional filling" of root canals with thermoplastic guttapercha cones. Before the filling phase, it is essential to know the accurate apical diameter of the canal, in order to choose the suitable filling material (gutta percha points, Thermafil obturators or heat carriers), followed by applying optimal condensation pressure in order to prevent overfilling.
