“…It is worth noting that while five diamond coated tips needed replacement, no instrument breakage happened with the zirconium nitride coated tips. While this note was not a targeted outcome to be measured, it goes along with the results of Lin et al (19) and Wan et al (20) who reported that orthograde diamond coated tips are more prone to fracture.…”

Thirty-two freshly extracted single-rooted anterior teeth with fully developed apices were obtained, cleaning, shaping were done for each tooth by wave Gold rotary files and obturation were done, teeth were then divided equally in two groups, then apicoectomy was done by tungsten carbide bur and retrograde was done by angled ultrasonic tips, two angled ultrasonic tips were used in this study, diamonid-coated and zirconium nitride coated ultrasonic tips, time of preparation were measured and the tooth was weighed before and after by five digital scale to evaluate the cutting efficiency of ultrasonic tips, Results of intergroup comparison for working time showed E8-SD to have significantly higher mean value than SURG-1 (p<0.001). While results of intergroup comparison for the weight of removed dentine showed SURG-1 to have a significantly higher value (p<0.001), Within the limitations of the study, diamond-coated surgical retrograde tip (E8-SD) showed a significantly higher cutting efficiency that zirconium coated tip ( Surg-1).

“…Studies have shown that the acoustic flow and cavitation produced by ultrasound contribute to the cleaning capacity of the root canal irrigation (Jiang et al, 2010). This also makes them effective in several applications including root canal preparation, removal of pulp nodules and fractured instruments, and condensation of endodontic filling materials (Wan et al, 2014). However, regardless of the technique used, endodontic instruments might fracture within the root canal by improper use or pre-existing factors such as anatomical complications and weak points of the instrument itself related to the manufacturing process (Lopes et al, 2016).…”

Ultrasonic tips and anatomic finishing files have been used as strategies to improve the cleaning and disinfection of root canals, especially in complex anatomies. These instruments are also subjected to fractures, which can hinder the endodontic treatment and negatively affect the outcome. This article presents two cases of successful management of intracanal-fractured instruments with unfavourable prognosis, emphasizing on treatment protocols and outcomes. Two 14-year-old female patients underwent root canal treatment of teeth 37 (case 1) and 47 (case 2). During the final irrigation protocols, case 1 presented a fractured XP-Clean file within the mesiobuccal canal and within the distal canal in case 2, which also showed fractured E1-Irrisonic tips within the mesiobuccal and distal canals. Non-surgical management and bypassing retained instrument fragments were successful in both cases and they may be considered adequate approaches.

“…The only tips that fractured in their study were diamond coated. Wan et al 27 also found, using a custom testing apparatus and extracted tooth substrate, that the diamond coated tips were the ones that fractured. The authors also felt that tip thickness played a role in the resistance to fracture.…”

ObjectivesThe author conducted a study to determine the frequency and types of adverse events associated with endodontic ultrasonic devices as reported to the U.S. Food and Drug Administration (FDA) Manufacturer and User Facility Device Experience (MAUDE) database.MethodsEndodontic ultrasonic device–related adverse events reported to the MAUDE database from January 1, 2016, to October 31, 2020, were accessed and reviewed.ResultsA total of 1258 adverse event reports were submitted to the FDA MAUDE database, as classified under FDA product code ELC (ultrasonic scaler) during the study period. Among these reports, 403 were specific to the dedicated use of the 2 main types of ultrasonic devices used in endodontic treatment: ultrasonic tip devices and irrigation-related devices. Device malfunction-associated events, consisting primarily of device breakage, comprised 393 of the 1258 adverse event reports, whereas the remaining 10 reports were identified as being patient injury–related reports.ConclusionsThe frequency, root causes, and economic costs of ultrasonic tip device breakage remain largely unstudied. Ultrasonic endodontic device–related adverse events and patient injuries occurring within clinical practice may be underreported at the present time. Consequently, the risks and ultimate impacts to patients from ultrasonic endodontic device breakage, malfunction and unknown cause-related adverse events, and patient injuries during their clinical usage remain largely unknown at the present time. Eight of the 10 patient injury–related reports made to the FDA MAUDE database during the period under study, containing descriptions of varying degrees of injury severity, were associated with an irrigation-related device.
