Review
INTRODUCTION
Proresolving lipid mediators are specialized molecules (SPMs) involved in the active resolution of the inflammatory process by regulating tissue homeostasis. The aim of this study was to investigate the scientific literature to assess the potential of SPMs as an adjunct in the treatment of endodontic infection.
METHODS
Three electronic databases (PubMed, Web of Science, and Scopus) were searched from their inception until February 2020 (PROSPERO CRD42020164743). Supplemental research was performed by screening the references of the relevant studies eligible for inclusion. A quality assessment of animal studies was performed using the Animal Research: Reporting of In Vivo Experiments guidelines, whereas the Systematic Review Centre for Laboratory animal Experimentation Risk of Bias tool was used to assess the risk of bias.
RESULTS
A total of 3295 records were screened, and 8 articles meeting the criteria were included for this qualitative review. The eligible studies showed a high to moderate overall quality and a low to moderate risk of bias. SPMs positively affected the development of pulpitis and apical periodontitis in experimental animal models. The early treatment of pulpitis with the topical application of SPMs was beneficial to control inflammation within 24 hours from contamination. In addition, SPMs delivered within the root canals after disinfection were found effective in promoting periapical healing.
CONCLUSIONS
Our findings suggest that SPMs may play a role in the inception and treatment of pulpal-periapical diseases, and they should be considered for future research for developing new therapeutics as an adjunct to endodontic treatment.

Review
PURPOSE
Endodontic disease is one of the most common causes of bacterial odontogenic sinusitis (ODS). Diagnosing ODS of endodontic origin involves otolaryngologists confirming sinusitis, and dental specialists confirming endodontic sources. The purpose of this study was to conduct a multidisciplinary literature review to highlight clinical and microbiological features of ODS, and the most optimal diagnostic modalities to confirm endodontic disease.
METHODS
An extensive review of both medical and dental literature was performed by rhinologists, endodontists, and an infectious disease specialist. Frequencies of various clinical and microbiological features from ODS studies were collected, and averages were calculated. Different endodontic testing and imaging modalities were also evaluated on their abilities to confirm endodontic disease.
RESULTS
ODS patients most often present with unilateral sinonasal symptoms for over 3 months, purulence on nasal endoscopy, and overt dental pathology on computed tomography (CT). Subjective foul smell, and maxillary sinus cultures demonstrating anaerobes and α-streptococci (viridans group) may be more specific to ODS. For endodontic evaluations, cold pulp testing and cone-beam CT imaging are most optimal for confirming pulpal and periapical disease.
CONCLUSION
Diagnosing ODS requires collaboration between otolaryngologists and dental specialists. Clinicians should suspect ODS when patients present with unilateral sinonasal symptoms, especially foul smell. Patients will generally have purulent drainage on nasal endoscopy, and both sinus opacification and overt dental pathology on CT. However, some patients will have subtle or absent dental pathology on CT. For suspected endodontic disease, endodontists should be consulted for at least cold pulp testing, and ideally cone-beam CT.

Review
The objective of the present systematic review is to evaluate the success of pulpotomy in mature permanent teeth presented with irreversible pulpitis. The following databases were searched: PubMed, Oral and Dentistry Database, Cochrane, and CINAHL plus. We included studies published in the English language only. However, narrative reviews and case reports/series were excluded. The first electronic and hand search yielded a total of 2851 articles. After going through extensive screening and eligibility process, only six articles were finally selected for the review. The follow-up period ranged from 1 to 10 years. Randomized controlled trial compared pulpotomy with the root canal treatment and reported comparable and even better success of the pulpotomy (78% success). All the other studies have also shown better clinical and radiographic success of pulpotomy (68%-100%). Pulpotomy can be considered an alternative option for mature permanent teeth with irreversible pulpitis.

Meta-Analysis Review
BACKGROUND
The outcome of vital pulp treatment after carious pulp exposure is multifactorial and related to the procedure, biomaterial and pre-operative pulpal diagnosis.
OBJECTIVES
To conduct a systematic review and meta-analysis determining the outcome of direct pulp capping (DPC) in mature permanent teeth with a cariously exposed pulp and a clinical diagnosis of reversible pulpitis, and ascertain whether the capping material influences the outcome.
METHODS
Sources: MEDLINE Ovid-SP, Cochrane Central Register of Controlled Trials (CENTRAL), International Clinical Trials Registry Platform (ICTRP), ClinicalTrials.gov, Embase and Web of Science until April 2020. Inclusion: Prospective, retrospective cohort studies and randomized trials investigating DPC outcome or comparing different capping materials after carious pulp exposure. Exclusion: Primary teeth, mechanical, traumatic or not specified pulp exposure, teeth with irreversible pulpitis or no pulpal diagnosis. Risk of bias assessed using Cochrane and modified Downs and Black quality assessment checklist. Meta-analysis on combined clinical/radiographic outcome was performed using a random effect model. Success was defined as absence of signs and symptoms of irreversible pulpitis, apical periodontitis or loss of pulp vitality.
RESULTS
Quality assessment highlighted four non-randomized studies to be of fair and five of poor quality. Four randomized trials had a high risk of bias. The pooled success rate differed based on material and follow-up. Calcium hydroxide success rate was 74% at 6-months, 65% at 1-year, 59% at 2-3 years and 56% at 4-5 years. Mineral trioxide aggregate (MTA) success was 91%, 86%, 84% and 81% at the same time points. Biodentine success was 96% at 6-months, 86% at 1 year and 86% at 2-3 years. The meta-analysis revealed MTA had better success than calcium hydroxide at 1-year (OR 2.66, 95% CI; 1.46- 4.84, P = 0.001) and 2- to 3-year follow-up (OR 2.21, 95% CI; 1.42-3.44, P = 0.0004). There was no difference between MTA and Biodentine.
DISCUSSION
These results were based on poor methodological quality studies. The effect size for of MTA vs Ca(OH)2, although modest, was consistent with narrow CI.
CONCLUSIONS
Low-quality evidence suggests a high success rate for direct pulp capping in teeth with cariously exposed pulps with better long-term outcomes for MTA and Biodentine compared with calcium hydroxide.

There is a lack of evidence about the best approach for cavitated caries lesions with the possibility of pulpal involvement in primary teeth. Thus, the present authors aimed to verify the best treatment for deep caries lesions with or without pulp involvement in primary teeth. The search was conducted in MEDLINE/Pubmed and Web of Science databases until May 2020. Studies that compared techniques to manage deep caries lesions with at least 12 months of follow-up were included. The risk of bias was evaluated using the RoB tool. Network meta-analysis and pairwise meta-analyses were conducted considering the treatment clinical success as an outcome, according to the pulp health condition. From 491 potentially eligible studies, 9 were included. For deep caries lesions with pulp vitality, the Hall Technique presented the highest probability of success (78%). In the event of accidental pulp exposure, pulpectomy presented a 76% chance of providing the best clinical results. For pulp necrosis, no difference was observed between a pulpectomy and non-instrumented endodontic treatment (RR = 0.69; 95%CI: 0.21-2.33) Thus, it was concluded that the Hall Technique may be a better option for deep caries lesions with pulp vitality. In cases of accidental pulp exposure of vital teeth during caries removal, a pulpectomy may be considered the best option. However, there are insufficient studies to build up evidence about the best treatment option when irreversible pulpitis or pulp necrosis is present.

Meta-Analysis Review
Comparing the anaesthetic efficacy of 1.8 mL and 3.6 mL of anaesthetic solution for inferior alveolar nerve blocks for teeth with irreversible pulpitis: a systematic review and meta-analysis with trial sequential analysis.
BACKGROUND
The scientific literature is contradictory in relation to selecting the appropriate volume of local anaesthetic solution for inferior alveolar nerve blocks (IANB) when attempting to anaesthetize mandibular teeth with irreversible pulpitis.
OBJECTIVES
To compare the efficacy of 1.8 and 3.6 mL of the same anaesthetic solution for IANBs when treating mandibular teeth with irreversible pulpitis.
METHODS
A literature search was performed in PubMed, Scopus and EBSCOhost databases until May 2020. Randomized clinical trials published in English, comparing 1.8 with 3.6 mL of the same anaesthetic solution for IANBs in permanent mandibular teeth with irreversible pulpitis, were included. The risk of bias of the included trials was appraised using the revised Cochrane risk of bias tool. A meta-analysis was performed using the random-effects model. The effect of random errors on the results of the meta-analysis was evaluated by trial sequential analysis and the quality of evidence was appraised using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach.
RESULTS
Four clinical trials involving 280 teeth from patients with ages ranging from 18 to 65 years were included. Among the four trials, three were categorized as having a 'low' risk of bias and one was categorized as having 'some concerns'. The primary meta-analysis revealed that 3.6 mL of anaesthetic solution when administered for IANBs was associated with significantly greater success rates compared with 1.8 mL (RR = 1.94; 95% CI, 1.07, 3.52; I = 77%). Similarly, the results of the sensitivity analysis (restricting trials only to those that used the Heft-Parker visual analogue pain scale) revealed that the use of 3.6 mL significantly increased the success of IANBs compared with 1.8 mL. The trial sequential analysis confirmed the evidence for the beneficial effect of 3.6 mL to achieve success for IANBs was 'conclusive'. The quality of evidence was graded as 'high'.
CONCLUSION
Increasing the volume of anaesthetic solution from 1.8 to 3.6 mL improved the success rate for IANBs in mandibular molars with irreversible pulpitis. The quality of the evidence was 'high'. Future high-quality clinical trials are required with different types of anaesthetic solutions and other types of teeth.

Meta-Analysis Review
INTRODUCTION
The effectiveness of intracanal cryotherapy for reducing postoperative pain is unclear. The objective of this systematic review was to evaluate the effect of intracanal cryotherapy on postoperative pain after root canal therapy in patients with pulpal or periradicular pathosis.
METHODS
We searched PubMed, Embase, Scopus, and the Cochrane Library as well as the top 3 endodontic journals for relevant articles. We included randomized controlled trials that included adults. Our main outcome was postoperative pain intensity measured with a validated scale. We assessed the risk of bias using the Cochrane criteria and the quality of the included studies using Grading of Recommendation Assessment, Development, and Evaluation. We used a random-effects model for meta-analysis.
RESULTS
Eight studies involving 810 patients were included. The overall risk of bias was moderate. Seven of 8 studies used a visual analog scale to measure pain intensity. Compared with controls, intracanal cryotherapy significantly reduced postoperative pain at 6 (mean difference = -1.37; 95% confidence interval [CI], -0.61 to -2.14; P < .05; I = 76%; moderate-quality evidence) and 24 hours after the procedure (mean difference = -1.43; 95% confidence interval, -0.70 to -2.15; P < .05; I = 89%; moderate-quality evidence). There was no significant effect on pain at 48 and 72 hours and 7 days after the procedure.
CONCLUSIONS
Moderate-quality evidence suggests that intracanal cryotherapy (ie, using cold saline irrigation as a final irrigant) significantly reduces the intensity of pain at 6 and 24 hours after root canal therapy. Future clinical trials assessing the effectiveness of intracanal cryotherapy are advocated.

Meta-Analysis
OBJECTIVES
To describe the efficacy and number of side effects for the Gow-Gates mandibular block (GGMB) and Vazirani-Akinosi mandibular block (VAMB) compared to inferior alveolar nerve block (IANB) in patients requiring lower third molar (L3M) extraction.
MATERIALS AND METHODS
A systematic search was performed in three electronic databases and complemented with a manual search. The inclusion criteria were randomised clinical trials in healthy patients who underwent at least one L3M extraction. Screening and article selection were carried out by two independent reviewers. After data extraction, a meta-analysis was performed for the success rate, number of positive aspirations, and onset time outcomes.
RESULTS
Six randomised clinical trials were included out of the 367 potentially eligible papers. No significant differences were found in terms of success rate using GGMB (risk ratio [RR] 1.04; 95% confidence interval [CI] 0.92 to 1.18; P = 0.48) nor VAMB (RR 0.96; 95% CI 0.86 to 1.06; P = 0.41). The VAMB group exhibited a lower number of positive aspirations than the IANB group (RR 0.08; 95% CI 0.01 to 0.55; P = 0.01), but there was no statistically significant difference between the GGMB and IANB groups (RR 1.06; 95% CI 0.13 to 8.78; P = 0.96). The delayed onset was even longer in GGMB (mean difference [MD] 3.32 min; 95% CI 1.98 to 4.66; P < 0.001) and VAMB (MD 0.90 min; 95% CI 0.37 to 1.43; P = 0.0001) than IANB.
CONCLUSIONS
GGMB and VAMB seem to be effective and safe anaesthetic techniques for the removal of L3M, but these blocks exhibited a more delayed onset time than IANB.
CLINICAL RELEVANCE
GGMB and VAMB are safe and effective anaesthetic techniques for the removal of L3M. However, IANB can still be considered the first option since GGMB and VAMB exhibited more delayed onset times and variable buccal nerve anaesthesia.

Meta-Analysis
OBJECTIVES
Pain management for the extraction of the mandibular third molar is a challenge as compelling evidence in comparative anaesthetics is currently lacking.
MATERIALS AND METHODS
Thorough literature searches took place in PubMed, ScienceDirect, CENTRAL, Embase, Web of Science, CBM, and CNKI. Thirty-three trials were meta-analysed using a Bayesian statistical approach within the random-effects model. Grading of Recommendations Assessment, Development, and Evaluation was performed to determine the overall quality of evidence across all comparisons.
RESULTS
In terms of success rate, an inferior alveolar nerve block (IANB) injection of 2% lidocaine with epinephrine was less effective than a combined injection of buccal infiltration (BI) and lingual infiltration (LI) with a 4% articaine (RR = 0.85 [0.75, 0.96], P = 0.611). According to visual analogue scale (VAS), 2% lidocaine-IANB with epinephrine caused higher VAS scores than 4% articaine-IANB with epinephrine (MD = 0.84 [0.28, 1.40], P = 0.057), whereas 0.5% levobupivacaine-IANB showed lower scores than 2% lidocaine-IANB (MD = - 1.62 [- 2.97, - 0.28], P = 0.045). Also, 2% lidocaine-IANB with epinephrine presented longer latency than both 4% articaine-IANB with epinephrine (MD = 39.44 [16.97, 61.90], P < 0.001) and 4% articaine-BI + LI with epinephrine (MD = 164.41 [16.23, 312.58], P < 0.001); 4% articaine-IANB with epinephrine produced shorter latency than 0.5% bupivacaine-IANB with epinephrine (MD = - 42.92 [- 70.28, - 15.56], P = 0.106); 0.75% ropivacaine-IANB caused shorter onset of action compared with 2% lidocaine-IANB (MD = - 40.88 [- 65.50, - 16.26], P < 0.001). In addition, 2% lidocaine-IANB with epinephrine produced significantly shorter duration than both 4% articaine-IANB with epinephrine (MD = - 47.33 [- 57.88, - 36.77], P = 0.265) and 2% mepivacaine-IANB with epinephrine (MD = - 10.01 [- 19.59, - 0.44], P = 0.769). The duration of action triggered by 4% articaine-IANB with epinephrine was shorter compared with 0.5% bupivacaine-IANB with epinephrine (MD = - 64.17 [- 74.65, - 53.69], P = 0.926). Both 0.5% levobupivacaine-IANB and 0.75% ropivacaine-IANB produced longer duration of action than 2% lidocaine-IANB (MD = 333.70 [267.33, 400.07], P < 0.001) and (MD = 288.01 [287.67, 288.34], P = 0.634, respectively).
CONCLUSIONS
The network meta-analysis demonstrated that the intraosseous injection of 4% articaine with epinephrine had the most noteworthy success rate. However, the combination of BI and LI of 4% articaine with epinephrine, and IANB of 0.5% bupivacaine were, according to a VAS, the most effective. It should be noted that a rapid onset of action was produced by BI combined with LI of 4% articaine with epinephrine and IANB of 2% mepivacaine with epinephrine, while the most prolonged duration of action was generated by IANB of 0.5% levobupivacaine or 0.5% bupivacaine.
CLINICAL RELEVANCE
For a better understanding of local anaesthesia for the extraction of the third molar, our study was aimed to provide evidence to guide better dental practices in pain management for clinicians.
