“…There is still no consensus regarding this matter [ 57 , 58 , 59 ]. However, with the introduction of new heat-treated files and techniques, it seemed that the single-visit procedure has become a good treatment option [ 58 , 60 , 61 ]. According to the literature, both procedures had similar success rates of RCT regardless of the diagnosis (pulp vs. periapical tissue) [ 61 , 62 , 63 ].…”

According to the literature, both procedures had similar success rates of RCT regardless of the diagnosis (pulp vs. periapical tissue) [ 61 , 62 , 63 ]. During multiple-visit RCT, usually, an antiseptic medication (calcium hydroxide) is placed in the root canal system for further disinfection of the canals between treatment appointments [ 64 , 65 ].…”

The main goal of root canal treatment (RCT) is to eradicate or essentially diminish the microbial population within the root canal system and to prevent reinfection by a proper chemo-mechanical preparation and hermetic final obturation of the root canal space. The aim of this study was to assess the quality of the root canal filling and the number of visits needed for completing RCT by operators with different experience, including dentistry students (4th and 5th year), general dental practitioners (GDPs), and endodontists. Data from medical records of 798 patients were analyzed, obtaining 900 teeth and 1773 obturated canals according to the inclusion and exclusion criteria. A similar number of teeth was assessed in each group in terms of density and length of root canal filling and number of visits. The larger number of visits and the lower quality of treatment was observed for 4th year students than for other groups (p < 0.05); in contrast, the endodontists needed the lowest number of visits to complete RCT and more often overfilled teeth than other operator groups (p < 0.05). Interestingly, no statistical difference in quality of root canal filling was noted between 5th year students, GPDs and endodontists. The treatment of lower teeth demanded statistically more visits than that of upper teeth (p < 0.05). The results of the study emphasize that most of the root canal filling performed by operators was considered adequate, regardless of tooth type, files used and number of visits.

Effectiveness of adjunct therapy for the treatment of apical periodontitis: A systematic review and meta‐analysis

et al. 2022

BackgroundAdjunct therapy refers to any intracanal procedure going beyond chemomechanical preparation with instruments and traditionally delivered irrigants (excluding interim dressings). It is not clear whether and which of these adjunct therapies have a significant impact on the outcome of root canal treatment [healing of apical periodontitis (AP) and other patient‐related outcomes].ObjectivesThis systematic review aimed to analyse available evidence on the effectiveness of adjunct therapy for the treatment of AP in permanent teeth, according to a population, intervention, comparison, outcome, time and study design framework formulated a priori by the European Society of Endodontology.MethodsFive electronic databases (PubMed, Embase, Scopus, Cochrane and Web of Science) were searched up to October 2021 to identify clinical studies comparing adjunct therapy to no adjunct therapy in adult patients with AP. Animal studies, reviews, studies with less than 10 patients per arm and studies with a follow‐up time of less than 1 year, or less than 7 days for postoperative pain, were excluded. The quality of the included studies was appraised by the appropriate tools [Risk of Bias 2 (RoB2) for randomized clinical trials (RCTs) and Newcastle–Ottawa Scale for observational studies]. Meta‐analysis was performed using a random‐effects model. The certainty of the evidence was assessed using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach.ResultsFourteen studies (13 RCTs and one retrospective cohort) fulfilled the inclusion criteria for this review. They evaluated different types of adjunct therapy: antimicrobial photodynamic therapy (aPDT; three studies), diode laser canal irradiation (3), Nd:YAG laser canal irradiation (2), Er;Cr:YSGG laser canal irradiation (1), ozone therapy (2) and ultrasonically activated irrigation (UAI) (4). Radiographical healing was reported in seven studies, but meta‐analysis was only possible for UAI (two studies), showing no statistically significant difference in healing after 12 months. Pain after 7 days was reported in seven studies. Meta‐analysis on three studies that used aPDT and on two studies using diode laser irradiation showed no significant difference in the prevalence of pain after 7 days between the control and adjunct therapy. According to RoB2 tool, six studies had a high risk of bias, five studies had some concerns, and two studies low risk of bias. The GRADE assessment revealed a very low strength of evidence for diode laser, and low strength of evidence for PDT, ozone and UAI studies.DiscussionThe included studies displayed significant heterogeneity in terms of type of adjunct therapy, technical details per adjunct therapy, outcome reporting and several combinations of these, limiting the potential for meta‐analysis.ConclusionsThere is insufficient evidence to recommend any adjunctive therapy for the treatment of apical periodontitis.RegistrationProspero CRD42021261869.

“…Unfortunately, the coinciding drawbacks of calcium hydroxide preparations occasionally exclude their use or increase the risk of unfavorable outcomes. This includes a high sensitivity to moisture, causing its dissolution and washing out, lack of adhesion to the dentine or to bonding systems which is responsible for microleakage and post treatment sensitivity [6,7,10]. The relatively low diffusion coefficient of calcium hydroxide, impeding the achievement of high concentrations of the ions in tissues, and the significant decrease of pH from 12.5 to 8.0 in 2-3 weeks cause prolongation of the treatment of contaminated root canals which in turn may weaken the tooth and increase the risk of fracture of the crown.…”

“…It was introduced into dentistry in the 19 th century and since that time it has been commonly used in various indications, especially due to its strong alkalizing, antibacterial, antinflammatory potential as well as its capacity to stimulate pulpal regenerative processes [5][6][7][8][9][10]. The mechanism of action of calcium hydroxide products is based on its ability to dissociate in aqueous solutions into free Ca 2+ ions and hydroxyl ions which activate many chemical reactions in contact with vital tissue as well as provide a highly alkaline environment with pH of approximately 12.5 [5][6][7][8][9][10]. Free hydroxyl ions show enormous reactivity with many various biomolecules.…”

A Comparison of Selected Regenerative Materials Used in the Management of Pulp Diseases – Review of the Literature

2015

The authors present a group of regenerative materials recommended for the treatment of deep caries, pulp exposure, endodontic treatment of immature teeth involving apexogenesis and apexification, and management of internal resorption and chronic periapical inflammations. Biomaterials which demonstrate biocompatibility, expressed by direct integration with dentine on a molecular level, also stimulate the formation of secondary and reparative dentine by odontoblasts. Calcium hydroxide is the oldest and has been the most widely used biomaterial since the 19 th century. However, due to some inconveniences experienced during treatment with this material, modern odontotropic materials like Mineral Trioxide Aggregate (MTA) or Biodentine are more frequently and more preferably used. New materials like MTA and Biodentine make it possible to develop new protocols of treatment and create opportunities for their successful results. Biodentine, in comparison with MTA, seems to be easier to prepare and apply, with a much shorter setting time. However it should be emphasized that observations of the performance of these new regenerative materials are relatively limited, so further research is required to confirm their long term performance and usefulness and to formulate reliable conclusions (Dent. Med. Probl. 2015, 52, 4, 485-490).
