“…The present study showed that all of the file systems had an improved TTF/NCF when FRM was employed, in accordance with the findings derived from V Faus-Matoses (2022) [29], Ferreira F et al (2017) [46], and Van der Vyver 2020 [47], who indicated that the resistance of NiTi alloy endodontic rotary files to cyclic fatigue was better when reciprocating motion was used compared to CR.…”

This in vitro study aims to assess the cyclic fatigue resistance of the Protaper Ultimate (PTU) files compared to the Protaper Gold (PTG) and the M3 UDG (M3) files using various motion kinematics in simulated canals. As far as the authors are aware, no study has previously compared the three file systems before this current investigation. Therefore, closing this information gap is the goal of the current research. Methods: A total of (60 new endodontic files were randomly divided into 6 groups (10 files per group); groups 1, 3, and 5 used continuous rotation (CR), while groups 2, 4, and 6 used forward reciprocating motion (FRM). A manufactured stainless-steel artificial canal was used to perform the cyclic fatigue testing. The results were analyzed using Student’s t-test and two-way ANOVA. All pairwise comparisons revealed statistically significant differences in the time to failure (TTF) for every study group (p < 0.001), with the exception of the PTG and M3 files, which performed similarly using both CR and FRM. Conclusions: The PTU files performed better than the PTG and M3 files in terms of the TTF and number of cycles to failure (NCF) using both CR and FRM.

“…Liquid growth/viability assays were performed either as stand-alone procedures or prior to anti-biofilm activity measurements (30 reports 9,50,57,58, ) and as a comparative method in one 86 of the four reports that investigated EOW effectiveness by agar diffusion assays. 66,[86][87][88] In vitro adherence and anti-biofilm assays (36 reports) were performed using laboratory biofilm models (11 reports, 70,[73][74][75][77][78][79][89][90][91][92] ), extracted human teeth (14 reports 90,91,[93][94][95][96][97][98][99][100][101][102][103][104] ), bovine teeth (1 report 105 ) and biomaterial substrates (10 reports 24,61,83,[106][107][108][109][110][111][112] ).…”

ObjectivesThe objective of this scoping review was to map evidence of electrolysed oxidising water (EOW) as a biocide for dental applications of relevance to older people and identify research gaps.BackgroundEOW is an emerging, “green,” and cost‐effective biocide. There are no reviews on the landscape of EOW research as either an antiseptic or disinfectant in dental healthcare or its suitability for the oral healthcare of older people.Materials and MethodsThe review follows the PRISMA Extension for Scoping Reviews (PRISMA‐ScR) guidelines. Database searches (Google Scholar, PubMed, Web of Science, Ovid, Scopus and Science Direct) were undertaken using MESH terms and Boolean operators with no date restrictions, to identify full‐text, original reports published in English‐language peer‐reviewed journals.ResultsThe search yielded 114 papers that met the inclusion/exclusion criteria. Dental applications of EOW include its use as an endodontic irrigant (39%); mouth rinse/surgical irrigant (21%); disinfectant for dental unit water lines (19%) and dental biomaterials (17%); and for antimicrobial efficacy, effects on oral tissues and on dental material properties. Most studies (83%) evaluated a single EOW formulation (acidic, moderately acidic or neutral) that was either generated at ‘point‐of‐use’ (POU; 72%), bottled (‘ready‐to‐use’, RTU; 24%) or from unspecified (3%) sources. Six reports evaluated storage‐related parameters and 25 evaluated clinical applications; 89 were in vitro studies and one investigated the cost‐effectiveness of POU EOW.ConclusionsNeutral‐pH, EOW is effective as an antimicrobial agent without deleterious effects on oral tissues. However, research on the impact of storage conditions, anti‐Candida biofilm efficacy and mechanism of action against yeasts, long‐term effects on denture materials and cost‐effectiveness is required to establish the suitability of EOW as a multipurpose biocide for dental healthcare, including infection‐control requirements relating to older people.

“…Ledge formation typically occurs when rigid files with sharp, inflexible cutting tips are used in a rotational motion within a curved root canal. It can also result from the repeated application of pressure with the same file at a certain level, especially before the beginning of an apical curve, the use of nonprecurved stainless steel files, insufficient pre-flaring, or the absence of a glide path [11] (Fig. 2).…”

“…The only chance to address this error is to introduce into the canal a fine K-file (08 to 010), very strongly precurved, with 1-2 mm apical slight movements and a 30° watch-winding rotation, which will inevitably deviate from the false trajectory [11,13].…”

Introduction: Endodontic therapy is a complex procedure that requires a high level of precision due to the intricacies of the root canal system. Despite advancements in endodontic tools and techniques, incidents such as instrument fractures, dentinal plugs, false routes, and root perforations can occur when best practice recommendations are not adhered to. These complications pose a significant public health concern as they can lead to potentially severe infectious complications and ultimately result in endodontic treatment failure. The aim of this study is to elucidate the causes of endodontic complications, particularly during the root canal shaping stage, and to identify strategies for their prevention.Materials and Methods: A cross-sectional, analytical, descriptive, and unidirectional study was conducted on a randomly selected sample of 300 private dentists in Casablanca. The questionnaires were completed anonymously, and statistical analyses were performed using SPSS software. The discussion will be enriched through a comprehensive literature search of major databases, complemented by a series of clinical cases illustrating these complications and the means by which they can be mitigated.Results: The study reveals that 91% of dentists encountered complications during endodontic therapy, with 284 dentists (94.98%) experiencing complications during root canal shaping. The most prevalent complication was instrument fracture, reported by 235 dentists (82.75%). Key contributing factors to these complications included forced file passage, non-adherence to the instrumental sequence, and absence or inadequacy of irrigation. However, these incidents can be averted by adhering to a meticulous treatment protocol and respecting the various steps critical to the success of root canal shaping.Conclusion: In conclusion, there exists a disparity between recommended best practices and the current practices in the field of endodontics, which can lead to multiple complications and subsequent endodontic treatment failures.
