Special Issue Information

Dear Colleagues,

The first two decades of the 21st century have seen spectacular developments in the dental sciences and related technologies, which have also transformed the way we think of endodontics. What was once not much more than root canal treatment is now an entire complex subdiscipline of dentistry equipped with an armamentarium of the latest technologies, including surgical microscopes, high-resolution digital imaging and computer-assisted guided surgery tailored to the individual patient’s needs. This development offers the practitioner an ever-growing set of tools to save patients’ teeth with ever-growing success rates.

This Special Issue aims to provide an overview of the latest research in endodontics and endodontic surgery, from bench science to chairside and clinical studies. The Special Issue features studies that can further our understanding of the latest issues and developments in the field and help the readers familiarize themselves with the state of the art in endodontics.

Topics of potential interest include (the list is not exhaustive):

Static and dynamic navigation in endodontic surgery;
The role and accuracy of digital (CBCT) imaging in endodontics;
The advantages and limitations of new technologies;
Success and survival in endodontics;
Materials and material-related issues;
Preclinical research regarding emerging endodontic techniques.

Abstract

Endodontic preparation with ultrasonic instruments can lead to temperature rise (TR) on the external root surface (ERF), which may damage the periodontium. The aim was to measure the TR due to the ultrasonic preparation applied at different energy levels and durations during the removal of broken endodontic instrument from the root canal. Thirty-five maxillary central incisors were decoronated and 4 mm of NiTi instruments were fractured 5 mm from the most coronal part of the root. The roots were divided into seven groups according to the preparation mode (endodontic-E5, periodontal-P3) and preparation duration (30 s, 45 s, 60 s). Ultrasonic preparation was performed in periods consisting of four preparation phases with intermediate irrigations and drying. During all preparations, the TR was recorded on ERF using a K-type thermocouple. The results demonstrated that the TR measured at the end of the preparation period was higher than at baseline in all groups (p < 0.001). The largest TR (8.0 ± 0.5 °C) occurred at high energy level (P3) with 60 s preparation duration (p < 0.001). The TR measured after rinsing was significantly lower than before rinsing (p < 0.001). In conclusion, rinsing between ultrasonic preparation phases can reduce the TR, which might be potentially harmful using high-energy exceeding 60 s. Full article

Comparison of the Three-Dimensional Accuracy of Guided Apicoectomy Performed with a Drill or a Trephine: An In Vitro Study

Abstract

Guided apicoectomy performed with 3D-printed polymer-based static surgical guides is an emerging trend in endodontic surgery. Static-guided apicoectomy is carried out with either a drill or a trephine. The aim of this in vitro study was to assess the accuracy of osteotomy and apicoectomy performed through a polymer guide, with both drill and trephine, and to compare the accuracy achievable with the two instruments. Six plaster models of a maxilla master model with extracted human maxillary teeth in polymethyl-methacrylate resin were used. The modeled osteotomies were performed in these. The master model was CBCT-scanned, and digital surgical plans were prepared, based on which the surgical guides were printed. The plans contained both drill and trephine apicoectomies. Digital three-dimensional position analysis was performed with dedicated algorithms. A total of 39 drill and 47 trephine osteotomies were analyzed. A statistically significant difference between the two instruments was found only in the global deviation of the distal endpoint, indicating lower deviation for the trephine procedure (1.53 mm vs. 1.31 mm, p = 0.038). Nevertheless, from a clinical perspective, this distinction is inconsequential. The results suggest that, for all practical purposes, the two approaches to apicoectomy allow the same level of accuracy. Full article

Abstract

Purpose: Recently, a novel approach to apicoectomy has emerged, involving the use of a hollow trephine with a surgical guide. This innovative technique creates a semicircular section, in contrast to the conventional straight cut (with a bur). The semicircular shape of this section raises questions about the method’s effectiveness in eliminating supernumerary canals (SNCs), which are auxiliary canals alongside the main root canal. These canals pose a risk of further infection if not thoroughly eliminated. The aim of this exploratory study was to assess the efficacy of the proposed method in the removal of SNCs. Methods: A sample of 200 extracted single-rooted human teeth was rigorously narrowed down by multiple steps to 33 specimens that contained SNCs in the apical third. These specimens underwent apical semicircular sectioning, removing the apical 3 mm of the root. The specimens then underwent repeated CT scanning. For samples with residual SNCs, the section was transformed into a straight section and another CT scan was performed. Results: The semicircular section eliminated all SNCs in 94% of the specimens, and it eliminated 97.3% of the SNCs in all specimens. The straight-line sectioning eliminated 98.6% of all SNCs and eliminated all SNCs in 96.97% of the SNC-containing teeth. Conclusions: The efficacy of semicircular apicoectomy performed with a trephine appears to be comparable (χ² = 1.00, df = 1, and p = 0.317) to that of the conventional straight apicoectomy performed with a bur as reported in the literature.
