- Objectives
The study aimed to conduct a bibliometric analysis of the GentleWave system (Sonendo, Inc.).
Methods
An electronic search was conducted in June 2024 using the Web of Science Collection database. Two reviewers independently screened publications, extracting data on authorship, publication details, study design, and citation metrics. Statistical analyses were performed in R to assess variable correlations, while the VOSviewer (Visualization of Similarities Viewer) software was used to map author and keyword networks.
Results
The search yielded 47 records, with 32 studies included. Publications spanned 2014 to 2024. The Journal of Endodontics published the highest number of studies (n = 15), and the International Endodontic Journal had the highest impact factor (5.4). The University of British Columbia and Sonendo, Inc. were the most frequent affiliations. Among the 32 articles, 28 were in vitro studies, primarily focusing on microbiology (n = 9). A total of 95 authors were identified, with Haapasalo and Shen being the most cited (n = 229). The articles accumulated 495 citations, demonstrating a strong positive correlation between the number of studies and citation counts (r = 0.98).
Conclusions
The analysis highlights a predominance of in vitro studies. Geographic concentration in the United States and Canada limits diversity, while the strong correlation between study numbers and citations suggests that increased publication volume enhances visibility.

- Objectives
The aim of this study was to investigate the efficacy of three newly introduced rotary endodontic systems: Genius ProFlex (Medidenta), TruNatomy (Dentsply Maillefer), and ZenFlex (Kerr).
Methods
Forty-five mandibular molars with root canal curvatures <5° were utilized. Micro-computed tomography scans were performed pre- and post-preparation to assess apical transportation, centralization, percentage of dentin wear, and canal volume alterations. Eight instruments of each diameter underwent cyclic fatigue testing.
Results
The percentage of dentin wear on mesial and distal walls showed no significant differences among ZenFlex, TruNatomy, and Genius ProFlex at 1, 2, 3, and 4 mm from the apical foramen and root canal orifice (p > 0.05). Centering ability varied in the mesiolingual canal (p < 0.05). No notable differences were observed in transportation (p > 0.05). Genius ProFlex demonstrated lower volumetric changes (p < 0.05). There were significant differences in cyclic fatigue, with higher values for Genius ProFlex and lower values for TruNatomy (p < 0.05).
Conclusions
The three nickel-titanium rotary instruments are safe and efficient for root canal preparation, with Genius ProFlex exhibiting superior cyclic fatigue resistance.
