“…The highest values of bond strength have been observed using the lateral condensation technique (LCT) and Tagger's hybrid technique (THT). 86 Similar results were obtained in another study wherein the strengths of the bonds to human dentin using AH Plus/gutta-percha (GP), Sealer 26/GP, Epiphany SE/Resilon, and Epiphany SE/GP root canal filling materials, when LCT or THT were used, were evaluated by means of push-out tests. The highest pushout forces were obtained when the canals were obturated using LCT with AH Plus and GP, followed by Sealer 26 and GP.…”

“…87 On the other hand, the lowest bond strengths were found with the continuous wave condensation technique, which could be explained by the presence of a thin cement layer, although the micro-CT images showed better results regarding the filling quality. 86 Considering the need for heat to obtain a positive result in thermoplasticized GP techniques, a systematic review compared these techniques to cold lateral condensation, using micro-CT to evaluate the quality of root canal filling. 88 Although it was evidenced that neither technique could completely obturate the root canal, thermoplasticized techniques did have significantly fewer voids in most studies, which is clinically desirable.…”

The correct obturation of the root canal system achieved by means of a core and a cement is essential for the success of endodontic treatment. There are several root canal cements (RCCs) on the market; however, because of their excellent characteristics, epoxy resin-based sealers (ERBSs) have been widely used. The main aim of this review was to analyze and integrate the available information on different ERBSs. An electronic search was performed in the PubMed and Scopus databases, using "epoxy resin" AND "root canal treatment", and "epoxy resin" AND "endodontics" as search terms. In general, ERBSs have good flow properties, film thickness, solubility, dimensional stability, sealing capacity, and radiopacity. They are also able to adhere to dentin while exhibiting low toxicity and some antibacterial effects. However, their main disadvantage is the lack of bioactivity and biomineralization capability. A large number of ERBSs are available on the market, and AH Plus keeps being the gold standard RCC. Yet, information on many of them is limited or non-existent, which could be due to the fact that some of them are relatively new. The latter emphasizes the need for relevant research on the physicochemical and biological properties of some ERBSs, with the aim of supporting their clinical use with sufficient evidence via prospective and long-term studies.

“…Though theoretically possible, practical in vitro studies presented here do not confirm this. Studies that evaluated the two techniques and found significantly fewer voids in thermoplasticized GP also demonstrate that the filling of isthmuses and lateral canals occurs with the sealer [77,80].…”

Complete Obturation—Cold Lateral Condensation vs. Thermoplastic Techniques: A Systematic Review of Micro-CT Studies

To prevent re-infection and provide a hermetic seal of the root canal system, an endodontist must aim to produce a void-free obturation. This review aimed to compare the completeness of root canal obturation between the two most prevalent methods—cold lateral condensation and warm gutta-percha techniques—using micro-CT (PROSPERO reg no. 249815). Materials and Methods: A search of Scopus, Embase, PubMed (Medline via PubMed), and Web of Science databases was done without any time restriction according to the PRISMA protocol. Articles that compared both techniques and were published in English were included. Data was extracted and the risk of bias was assessed using an adapted tool based on previous studies. Results: A total of 141 studies were identified by the search. Following the screening and selection of articles, 9 studies were included for review. Data was extracted manually and tabulated. Most studies had a moderate risk of bias. None determined operator skill in both methods before comparison. The data extracted from the included studies suggests that both techniques produce voids in the obturation. The thermoplasticized gutta-percha techniques may result in fewer voids compared to cold lateral condensation. Conclusion: Considering the limitations of the included studies, it was concluded that neither technique could completely obturate the root canal. Thermoplasticized gutta-percha techniques showed better outcomes despite a possible learning bias in favor of cold lateral condensation. Establishing operator skills before comparison may help reduce this bias.

Micro-computed tomography and bond strength analysis of different root canal filling techniques

Abstract: It can be concluded that LCT and THT were associated with higher bond strengths to intraradicular dentine than CWCT. However, LCT was associated with more empty voids than the other techniques.
