Root canal preparation: A literature review and clinical case reports of available materials and techniques

INTRODUCTION: Moyers analysis is widely used for analyzing mixed dentition, however, the accuracy of its theoretical probability tables has been recently questioned. Taking into consideration the fact the mixed dentition analysis is of paramount importance to precisely determine the space needed for alignment of canines and premolars, this research aimed at objectively assessing in the literature such an important step for orthodontic diagnosis. METHODS: A computerized search involving articles published on PubMed and Lilacs between 1990 and September, 2011 was conducted in accordance with the method described in the Cochrane 5.1.0 handbook. RESULTS: The research resulted in a sample composed of 629 articles. The inclusion criteria were: Articles using the Moyers analysis with a sample greater or equal to 40 patients. Conversely, the exclusion criteria were: Dental casts of patients with syndromes or oral cleft, researches conducted with a literature review, only, or clinical case reports and researches conducted before 1990. For this systematic review, 19 articles were selected. CONCLUSION: Based on the literature available, we can conclude that the Moyers mixed dentition analysis must be carefully used, since the majority of the articles analyzed showed that the probability of 75% was not as accurate as expected, leading to the need of adapting the probability levels depending on the study population.

Objective: the purpose of this literature review was to evaluate apical debris extrusion after root canal preparation with Protaper Universal and Protaper Next Rotary systems. Material and Methods: the question that supported the collection of scientific evidence for the present study was: Which rotary system presents the best performance regarding the apical extrusion of debris: Protaper Universal or Protaper Next? From the online search databases, a bibliographic research was carried out covering original research studies, using as descriptors: Apical extrusion debris, Protaper Universal and Protaper Next. Articles had to meet the following inclusion criteria: should have been published in the English language from 2014 to 2017 and should compare both mentioned rotary files systems regarding apical extrusion of debris in the same study. Ninety-six articles were found after research and six were included for this integrative review. Results: six studies remained included after the inclusion criteria analysis. Of these, 50% were published in 2016, 16.6% in 2015 and and 33% in 2014. Weight establishment of the extruded material was the methodology used in all studies to evaluate the performance of the files By analyzing the amount of apically extruded material, it was found that the Protaper Universal system extruded more quantity than the Protaper Next system. Conclusion: it was concluded that, although there is no system capable of performing the instrumentation without promoting apical extrusion, the Protaper Next rotary files system presented better performance when compared to the Protaper Universal files system, regarding the apical debris extrusion.

Venomous Fish

Stonefish are regarded as one of the most venomous fish in the world. Research on stonefish venom has chiefly focused on the in vitro and in vivo neurological, cardiovascular, cytotoxic and nociceptive effects of the venom. The last literature review on stonefish venom was published over a decade ago, and much has changed in the field since. In this review, we have generated a global map of the current distribution of all stonefish (Synanceia) species, presented a table of clinical case reports and provided up-to-date information about the development of polyspecific stonefish antivenom. We have also presented an overview of recent advancements in the biomolecular composition of stonefish venom, including the analysis of transcriptomic and proteomic data from Synanceia horrida venom gland. Moreover, this review highlights the need for further research on the composition and properties of stonefish venom, which may reveal novel molecules for drug discovery, development or other novel physiological uses.

Mandibular First Molar

In everyday endodontic practice, clinicians face various atypical configurations, such as presence of extra root and/or atypical canal configuration. One of the major reason of the treatment failure is the missed extra root and/or canals. Mandibular first molars typically have two roots (one mesial and one distal), but sometimes present with a supernumerary root either distolingually (radix entomolaris), or mesiobuccally (radix paramolaris). Hence, the thorough knowledge of root canal anatomy and morphology along with its variation is crucial for the successful outcome of the root canal treatment. The aim of this paper is to present and describe the three clinical case reports of three rooted mandibular first molars and its endodontic management.

The aim of this study was to undertake a literature review on the use of XP-endo Shaper (FKG Dentaire SA, La Chaux-de-Fonds, Switzerland) for root canal preparation evaluated using microcomputed tomography (micro-CT) technology, with emphasis on the analysis of untouched canal walls. We searched the PubMed, Science Direct, SciELO, and MEDLINE databases for articles published from 2017 to 2019 using the following keywords: micro-CT, untouched walls, XP shaper, and XP endo. Articles without an abstract were excluded. Five papers were selected. Few studies on this topic are available. The studies published so far show that the XP-endo® Shaper system performs well in terms of canal preparation but leaves untouched walls.

Root Fractures

Evidence indicates that root canal preparation is a critical step upon which the prognosis of the endodontic treatment depends. Vertical root fractures can furtherly develop as propagations from the previously formed dentin cracks. Therefore, root canal preparation should be carefully approached with the minimal crack formation and careful dentin removal. Different modalities have been proposed in the literature and rotary systems are most commonly used nowadays. Although the reported efficacy of these modalities is high, evidence shows that they are usually associated with a considerable risk of crack formation. In the present literature review, we have discussed the effects of rotary instrumentation and root canal preparation on dentinal crack formation based on evidence from the different studies in the literature. Our evidence showed that all of the investigated approaches to prepare root canals adequately can result in crack formation. The different rotary instrumentations also showed variable frequencies of developing dentinal cracks, and evidence from some comparative investigations shows that ProTaper modalities are associated with the least frequencies of the events. However, to make a solid conclusion for clinical practice, further research is still needed to validate our current evidence.
