PeerJ 2023The aim of this systematic review is to determine microRNAs (miRs) that are differently expressed between diseased pulpal and periapical tissues.
BACKGROUND
The aim of this systematic review is to determine microRNAs (miRs) that are differently expressed between diseased pulpal and periapical tissues.
DESIGN
This systematic review used PubMed, Scopus, EBSCO, ProQuest, Cochrane database as well as manual searching to extract studies from January 2012 up to February 2022.
RESULTS
A total of 12 studies met the eligibility criteria were included. All selected studies were of case-control type. Twenty-four miRNAs associated with apical periodontitis, 11 were found to be upregulatedand 13 were downregulated. Four out of the 44 miRs associated with pulpal inflammation were upregulated, whereas forty were downregulated. Six miRs, namely hsa-miR-181b, hsa-miR-181c,hsa-miR-455-3p,hsa-miR-128-3p, hsa-miR199a-5p, and hsa-miR-95, exhibited considerable downregulation in both periapical and pulp tissues.
CONCLUSION
MiRs have been investigated for their role in pulpal and periapical biology and may be utilised in diagnostic and therapeutic purposes. Further investigations are required to determine why certain irreversible pulpitis situations progress to apical periodontitis and others do not, based on the various miR expressions. Moreover, clinical and laboratory trials are needed to support this theory.

Review
BACKGROUND
Local anesthesia is essential for pain control in dentistry. The authors assessed the comparative effect of local anesthetics on acute dental pain after tooth extraction and in patients with symptomatic irreversible pulpitis.
TYPES OF STUDIES REVIEWED
The authors searched MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, and the US Clinical Trials registry through November 21, 2020. The authors included randomized controlled trials (RCTs) comparing long- vs short-acting injectable anesthetics to reduce pain after tooth extraction (systematic review 1) and evaluated the effect of topical anesthetics in patients with symptomatic pulpitis (systematic review 2). Pairs of reviewers screened articles, abstracted data, and assessed risk of bias using a modified version of the Cochrane risk of bias 2.0 tool. The authors assessed the certainty of the evidence using the Grading of Recommendations Assessment, Development and Evaluation approach.
RESULTS
Fourteen RCTs comparing long- vs short-acting local anesthetics suggest that bupivacaine may decrease the use of rescue analgesia and may not result in additional adverse effects (low certainty evidence). Bupivacaine probably reduces the amount of analgesic consumption compared with lidocaine with epinephrine (mean difference, -1.91 doses; 95% CI, -3.35 to -0.46; moderate certainty) and mepivacaine (mean difference, -1.58 doses; 95% CI, -2.21 to -0.95; moderate certainty). Five RCTs suggest that both benzocaine 10% and 20% may increase the number of people experiencing pain reduction compared with placebo when managing acute irreversible pulpitis (low certainty).
PRACTICAL IMPLICATIONS
Bupivacaine may be superior to lidocaine with epinephrine and mepivacaine with regard to time to and amount of analgesic consumption. Benzocaine may be superior to placebo in reducing pain for 20 through 30 minutes after application.

Review
Clinical question Is cervical pulpotomy a viable treatment alternative to conventional root canal treatment for management of acute irreversible pulpitis in mature permanent teeth?Data sources A comprehensive literature search was performed on PubMed and Cochrane Library covering the years 2000-2021 for randomised clinical trials addressing the defined clinical question. The title and abstract were reviewed by two authors independently and any conflict was resolved by discussion with the third author.Study selection Only randomised controlled trials studies that compared cervical pulpotomy against non-surgical root canal treatment were included in this systematic review. Studies dealing with primary teeth or immature permanent teeth were excluded.Data extraction and synthesis Studies that reported clinical and radiographic success rate with a minimum follow-up of six months were included. The authors tabulated the data from primary sources without any synthesis.Results Only four studies fulfilled the inclusion/exclusion criteria. The results indicate that the clinical success rate of pulpotomy was comparable to root canal treatment while the radiographic success rate was higher in pulpotomy.Conclusions Pulpotomy is not inferior to the conventional root canal treatment for the management of acute irreversible pulpitis in mature permanent teeth in adults.

Review
BACKGROUND
Root canal treatment (RoCT), or endodontic treatment, is a common procedure in dentistry. The main indications for RoCT are irreversible pulpitis and necrosis of the dental pulp caused by carious processes, coronal crack or fracture, or dental trauma. Successful RoCT is characterised by an absence of symptoms (i.e. pain) and clinical signs (i.e. swelling and sinus tract) in teeth without radiographic evidence of periodontal involvement (i.e. normal periodontal ligament). The success of RoCT depends on a number of variables related to the preoperative condition of the tooth, as well as the endodontic procedures. RoCT can be carried out with a single-visit approach, which involves root canal system obturation (filling and sealing) directly after instrumentation and irrigation, or with a multiple-visits approach, in which the treatment is completed in two or more sessions and obturation is performed in the last session. This review updates the previous versions published in 2007 and 2016.
OBJECTIVES
To evaluate the benefits and harms of completion of root canal treatment (RoCT) in a single visit compared to RoCT over two or more visits, with or without medication, in people aged over 10 years.
SEARCH METHODS
We used standard, extensive Cochrane search methods. The latest search date was 25 April 2022.
SELECTION CRITERIA
We included randomised controlled trials and quasi-randomised controlled trials in people needing RoCT comparing completion of RoCT in a single visit compared to RoCT over two or more visits. DATA COLLECTION AND ANALYSIS: We used standard Cochrane methods. Our primary outcomes were 1. tooth extraction and 2. radiological failure after at least one year (i.e. periapical radiolucency). Our secondary outcomes were 3. postoperative and postobturation pain; 4. swelling or flare-up; 5. analgesic use and 6. presence of sinus track or fistula after at least one month. We used GRADE to assess certainty of evidence for each outcome. We excluded five studies that were included in the previous version of the review because they did not meet the current standard of care (i.e. rubber dam isolation and irrigation with sodium hypochlorite).
MAIN RESULTS
We included 47 studies with 5805 participants and 5693 teeth analysed. We judged 10 studies at low risk of bias, 17 at high risk of bias and 20 at unclear risk of bias. Only two studies reported data on tooth extraction. We found no evidence of a difference between treatment in one visit or treatment over multiple visits, but we had very low certainty about the findings (risk ratio (RR) 0.46, 95% confidence interval (CI) 0.09 to 2.50; I = 0%; 2 studies, 402 teeth). We found no evidence of a difference between single-visit and multiple-visit treatment in terms of radiological failure (RR 0.93, 95% CI 0.81 to 1.07; I = 0%; 13 studies, 1505 teeth; moderate-certainty evidence). We found evidence of a higher proportion of participants reporting pain within one week in single-visit groups compared to multiple visit groups (RR 1.55, 95% CI 1.14 to 2.09; I = 18%; 5 studies, 638 teeth; moderate-certainty evidence). We found no evidence of a difference in the proportion of participants reporting pain until 72 hours postobturation (RR 0.97, 95% CI 0.81 to 1.16; I = 70%; 12 studies, 1329 teeth; low-certainty evidence), pain intensity until 72 hours postobturation (mean difference (MD) 0.26, 95% CI -4.76 to 5.29; I = 98%; 12 studies, 1258 teeth; low-certainty evidence) or pain at one week postobturation (RR 1.05, 95% CI 0.67 to 1.67; I = 61%; 9 studies, 1139 teeth; very low-certainty evidence). We found no evidence of a difference in swelling or flare-up incidence (RR 0.56 95% CI 0.16 to 1.92; I = 0%; 6 studies; 605 teeth; very low-certainty evidence), analgesic use (RR 1.25 95% CI 0.75 to 2.09; I = 36%; 6 studies, 540 teeth; very low-certainty evidence) or sinus tract or fistula presence (RR 1.00, 95% CI 0.24 to 4.28; I = 0%; 5 studies, 650 teeth; very low-certainty evidence). Subgroup analysis found no differences between single-visit and multiple-visit RoCT for considered outcomes other than proportion of participants reporting post-treatment pain within one week, which was higher in the single-visit groups for vital teeth (RR 2.16, 95% CI 1.39 to 3.36; I = 0%; 2 studies, 316 teeth), and when instrumentation was mechanical (RR 1.80, 95% CI 1.10 to 2.92; I = 56%; 2 studies, 278 teeth).
AUTHORS' CONCLUSIONS
As in the previous two versions of the review, there is currently no evidence to suggest that one treatment regimen (single-visit or multiple-visit RoCT) is more effective than the other. Neither regimen can prevent pain and other complications in the 12-month postoperative period. There was moderate-certainty evidence of higher proportion of participants reporting pain within one week in single-visit groups compared to multiple-visit groups. In contrast to the results of the last version of the review, there was no difference in analgesic use.

Meta-Analysis Review
OBJECTIVES
To determine the clinical performance of light-cured calcium silicate-based cement for direct or indirect pulp capping. The research question was as follows: in teeth with deep caries lesions, does the use of resin-modified calcium silicate-containing composites improve the radiological success and prevent irreversible pulpitis and pulpal necrosis compared with other pulp-capping agents?
MATERIALS AND METHODS
The following databases were screened until September 2021: PubMed, Web of Science, Scielo, Scopus, Embase, and The Cochrane Library. Randomized clinical trials reporting the clinical evaluation of a resin-modified calcium silicate material as an agent for pulp therapy were included. Meta-analysis was performed using the Rev Manager v5.4.1 software. The risk difference and 95% confidence interval of the dichotomous outcome (restoration failure or success) were calculated for comparison.
RESULTS
Ten studies were considered for qualitative analysis and meta-analysis. Studies evaluating the performance of light-cured calcium silicate-based cement from 1 month to a maximum follow-up period of 36 months and comparing it with the performance of CaOH, mineral trioxide aggregate, or Biodentine were included. In the global analysis for direct pulp capping at 6-month follow-up, no statistical differences were observed between the experimental group using the light-cured calcium silicate-based cement and control group (P = .28). However, at 12-month follow-up, global analysis favored the control group (P < .001). For indirect pulp capping, at 6- and 24-month follow-ups, no statistically significant differences were observed between the experimental and control groups (P = .88; P = .21).
CONCLUSIONS
Light-cured calcium silicate-based cement showed a limited clinical performance as a direct pulp capping agent, especially when evaluated in the long term. However, using it as an indirect pulp capping agent may be a reliable and easy-to-use option for restoring teeth with deep caries.
CLINICAL SIGNIFICANCE
This systematic review provides evidence that supports the use of light-cured calcium silicate-based cement as an indirect pulp capping agent.

Meta-Analysis
Treatment planning is key to clinical success. Permanent teeth diagnosed with "irreversible pulpitis" have long been implied to have an irreversibly damaged dental pulp that is beyond repair and warranting root canal treatment. However, newer clinical approaches such as pulpotomy, a minimally invasive and biologically based procedure have re-emerged to manage teeth with pulpitis. The primary aim of the study was to conduct a meta-analysis to comprehensively estimate the overall success rate of pulpotomy in permanent teeth with irreversible pulpitis as a result of carious pulp exposure. The secondary aim of the study was to investigate the effect of predictors such as symptoms, root apex development (closed versus open), and type of pulp capping material on the success rate of pulpotomy. Articles were searched using PubMed, Scopus, CENTRAL, and Web of Science databases, until January 2021. Outcomes were calculated by pooling the success rates with a random effect model. Comparison between the different subgroups was conducted using the z statistic test for proportion with significance set at alpha = 0.05. A total of 1,116 records were retrieved and 11 studies were included in the quantitative analysis. The pooled success rate for pulpotomy in teeth with irreversible pulpitis was 86% [95% CI: 0.76-0.92; I = 81.9%]. Additionally, prognostic indicators of success were evaluated. Stratification of teeth based on (1) symptoms demonstrated that teeth with symptomatic and asymptomatic irreversible pulpitis demonstrated success rate of 84% and 91% respectively, with no significant difference (p = 0.18) using z-score analysis; (2) open apex teeth demonstrated a significantly greater success rate (96%) compared to teeth with closed apex (83%) (p = 0.02), and (3) pulp capping materials demonstrated that Biodentine yielded significantly better success rates compared to Mineral Trioxide Aggregate (MTA), calcium hydroxide, and Calcium Enriched Mixture (CEM.) Collectively, this is the first meta-analytical study to determine the clinical outcome of pulpotomy for carious teeth with irreversible pulpitis and it's predictors for success. Moreover, we identify the stage of root development and type of biomaterial as predictors for success of pulpotomy.

Meta-Analysis Review
BACKGROUND
Pulpitis characterized by spontaneous pain can result in debilitating pain. Dogma has existed to offer only have two treatment options, namely root canal treatment (RCT) or extraction, although pulpotomy has always remained a potential treatment modality.
OBJECTIVE
This review aimed to answer the following research question: 'Does pulpotomy (partial or full) (I) result in better patient and clinical reported outcomes (O), compared with RCT (C) in permanent teeth with pulpitis characterized by spontaneous pain (P) evaluated at various time intervals?' (T).
METHODS
Two authors independently performed study selection, data extraction and risk of bias assessment. The literature search was conducted in the following electronic databases: Clarivate Analytics' Web of Science, Scopus, PubMed and Cochrane Central Register of Controlled Trials. English language clinical trials comparing the patient and clinical reported outcomes between RCT and pulpotomy were included. The meta-analysis was performed on a fixed-effect model and the quality of evidence assessed by the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach.
RESULTS
Two randomized clinical trials were included. Amongst two trials, one has published four reports at different time points involving the same cohorts. The meta-analysis revealed no difference in postoperative pain (Day 7) between RCT and pulpotomy (OR = 0.99, 95% CI 0.63-1.55, I = 0%) and quality of evidence was graded as 'High'. Clinical success was high at year 1, 98% for both interventions, however, decreased over time to 78.1% (pulpotomy) and 75.3% (RCT) at 5 years.
DISCUSSION
Pulpotomy is a definitive treatment modality that is as effective as RCT. This could have a significant impact on treatment of such patients affording the advantages of retaining a vital pulp and preventing the need for RCT.
CONCLUSION
This review could only include two trials, hence there is insufficient evidence to draw robust conclusions. The clinical data accumulated so far suggests no difference in pain between RCT and pulpotomy at Day 7 postoperatively and a single randomized control trial suggests that the clinical success rate for both treatment modalities is similar long term. There is a need for more well-designed trials by different research groups to develop a stronger evidence base in this area.

Review
Pulpotomy has been used in primary teeth and immature permanent teeth. However, with the advent of new bioactive material, the procedure is shifting towards permanent teeth with mature apices of roots. The objective of this systematic review was to evaluate the success of pulpotomy on mature permanent teeth with acute irreversible pulpitis and to compare it with root canal treatment or between the effectiveness of the bioactive material used. The following databases were searched: PubMed, Cochrane Library: Cochrane Central Register of Controlled Trials, Embase, ClinicalTrials.gov, International Clinical Trials Registry Platform. After using the keywords predefined, the electronic search yielded a total of 86 articles. After undergoing a thorough screening and eligibility process, only four articles were finally selected. Unexpectedly, pulpotomy demonstrated a better tendency for success in such cases over the years. This shows that pulpotomy is not inferior to root canal treatment for permanent treatment of irreversible pulpitis. In addition, the results obtained showed that pulpotomy is rapid, biologically reliable and more cost-effective in all situations compared to root canal therapy. Complete pulpotomy appears to have a high success rate as a permanent treatment of irreversible pulpitis and could be considered as an alternative to root canal therapy. Pulpotomy is not inferior to root canal treatment for a permanent treatment of irreversible pulpitis. In addition, the results obtained have shown that complete pulpotomy is faster and more profitable in all situations compared to root canal treatment. Furthermore, with the advent of new so-called bioactive materials, the use of this therapeutic is increasingly considered. This is why a review based on studies of reliable articles is above all necessary to be able to generalise the indication of this therapy.

Review
The major focus of this systematic review is to assess how effective partial pulpotomy is in managing carious vital pulp exposures in permanent posterior teeth. An electronic search for studies published between January 2011 and December 2021 was conducted using the following databases: PubMed, Scopus, Google Scholar, and Web of Science. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) criteria were followed during the search process. We selected human randomized clinical trials (RCTs) that investigated the success rate of partial pulpotomy for the treatment of cariously exposed vital permanent posterior teeth and the success rate of decayed exposed vital human permanent posterior dentition managed with a partial pulpotomy. Exclusively, randomized clinical trial papers were considered for assessment. The Cochrane Collaboration's tool was applied to assess the risk of bias. Four papers were selected for the final analysis from the 321 identified during the initial search. Our results showed that after six, 12, and 24 months of follow-up, the success rate was 94%, 93%, and 90%, respectively. The preoperative pulp state was the only significant predictive factor. Teeth with the presumptive diagnosis of irreversible pulpitis had the worse outcome. The treatment outcome was not influenced by the final restoration, pulp capping agent, apex closure, or patient age. Finally, the available data indicated that partial pulpotomy showed a high success rate in treating cariously exposed permanent posterior teeth for up to 24 months. When assessing the effectiveness of a partial pulpotomy, six months of maintenance is deemed adequate. To enhance treatment success, additional clinical and radiological measures are needed.
