EFFICACY OF 4% ARTICAINE BUCCAL INFILTRATION VERSUS INFERIOR ALVEOLAR NERVE BLOCK FOR MANDIBULAR MOLARS WITH SYMPTOMATIC IRREVERSIBLE PULPITIS: A SYSTEMATIC REVIEW AND META-ANALYSIS.
OBJECTIVES
To compare the anesthetic efficacy of buccal infiltration (BI) using 4% articaine vs 4% articaine or 2% lidocaine inferior alveolar nerve block (IANB) for mandibular molars with symptomatic irreversible pulpitis.
METHODS
PubMed, Cochrane, Web of Science, Scopus, and ClinicalTrials.gov were searched using MESH terms and specific keywords. Included articles were Randomized Clinical Trials (RCTs), which compared 4% articaine BI vs conventional IANB in terms of the efficacy of pulpal anesthesia and success rate. The quality assessment of included studies was done according to the Cochrane risk of bias assessment tool. Studies were quantitatively assessed using fixed or random effect models.
RESULTS
Out of 756 articles, 5 RCT studies were included with a total number of 500 patients: 231 in 4% articaine BI group, 150 in 2% lidocaine IANB group, and 119 in 4% articaine IANB group. Our meta-analysis results showed that patients anesthetized with 4% articaine BI had a similar success rate compared to 2% lidocaine IANB [pooled RD: 0.14 (95% CI, -0.01 to 0.29); P = .08]. Similarly, there was non-significant difference when compared to 4% articaine IANB [RD:-0.01 (95% CI, -0.13 to 0.11; P = .86)]. Patients anesthetized with 4% articaine BI presented comparable pain scores compared to IANB (4% articaine or 2% lidocaine) [pooled MD: -0.14 (95% CI, -0.38 to 0.11); P = .27]. Regarding quality assessment, 3 studies were considered to have a low risk of bias, one study has an unclear risk of bias, and one study has a high risk of bias.
CONCLUSION
4% articaine BI showed comparable results in terms of pain relief and success rate in comparison with 2% lidocaine IANB or 4% articaine IANB. However, due to the limited number and small sample size of included studies, these findings should be considered carefully, and further studies are required to confirm our findings.

Review
BACKGROUND
The exposed pulp has been the topic of numerous studies, but well-designed and well-executed comparative trials on the outcome and treatment of these teeth have been limited.
OBJECTIVES
This study was conducted to answer the following questions: in patients with nontraumatic pulpitis associated with no or nonspontaneous pain in permanent teeth, (i) is direct pulp capping or pulpotomy (partial/full) as effective as selective or stepwise caries removal [Population/participants, Intervention(s), Comparator(s)/control, Outcome(s) (PICO) 1], (ii) is pulpotomy (partial/full) as effective as direct pulp capping (PICO 2) and (iii) is pulpotomy (partial/full) as effective as a pulpectomy (PICO 3), in terms of a combination of patient and clinical reported outcomes, with 'tooth survival' as the most critical outcome?
METHODS
A literature search was conducted using Clarivate Analytics' Web of Science, Scopus, PubMed and Cochrane Central Register of Controlled Trials from inception to November 3rd 2021. Grey literature and contents of the major subject journals were examined. Eligibility criteria followed the PICO questions. Two independent reviewers performed study selection, data extraction and appraisal; disagreements were resolved by a third reviewer. The risk of bias was assessed by the revised Cochrane risk-of-bias tool for randomized trials.
RESULTS
Three randomized clinical trials (RCTs) were included in the review. No study fulfilled the criteria to answer PICO 1. There were no significant differences in the reported outcomes between investigated treatments in all included RCTs. None of the included studies reported the most critical outcome 'tooth survival'. A high loss of patients during the follow-up period was observed.
DISCUSSION
Although a few studies fulfilled strict eligible criteria, the results of this systematic review clearly highlight a paucity of available evidence. At the present time, clinical decisions cannot be substantiated by direct comparative trials.
CONCLUSIONS
Based on limited evidence, this systematic review discovered no significant differences in effectiveness between compared vital pulp treatments in managing nontraumatic pulpitis associated with no or nonspontaneous pain. Further high-quality RCTs are necessary to investigate the effectiveness of direct pulp capping or pulpotomy (partial/full) compared to selective or stepwise caries removal.

BACKGROUND
This study aimed to evaluate the effect of mineral trioxide aggregate (MTA) pulp capping for caries-exposed permanent teeth. However, the efficacy of MTA in the treatment of children's gums is still controversial, and different studies have shown different efficacy. Therefore, it is necessary to systematically review the efficacy and safety of MTA pulp incision in the treatment of pediatric caries using meta methods.
METHODS
We used meta-analysis to compare differences in the efficacy of MTA and calcium hydroxide (CH) for treating caries in permanent teeth. The mean treatment success rate of MTA for reversible and irreversible pulpitis groups was calculated, and the effect of apical opening condition and surgical type on success rate were investigated.
RESULTS
A total of 15 studies were included, and meta-analysis showed that there was a significant statistical difference between the MTA group and CH group in efficacy [odds ratio (OR) =1.87, 95% confidence interval (CI): 1.28, 2.73, P=0.001, I=63%, Z=3.25], success rate (OR =3.20, 95% CI: 1.93, 5.30, P<0.00001, I=0%, Z=4.52), influence of apical foramen condition on success rate (OR =1.77, 95% CI: 1.14, 2.73, P=0.01, I=15%, Z=2.56), and surgical procedure on success rate (OR =2.64, 95% CI: 1.65, 4.23, P<0.0001, I=45%, Z=4.05).
DISCUSSION
Our results showed that MTA pulpotomy was superior to CH. Nonclosure of apical openings and complete coronal pulpotomy may be more beneficial than partial pulpotomy.

Review
BACKGROUND
The diagnosis of the status of the inflamed pulp is essential in clinical diagnosis and treatment provision. There are a limited number of well-designed and well-executed clinical trials on the diagnosis of the true status of the pulp.
OBJECTIVES
Three PICO questions were formulated and agreed a priori by the European Society of Endodontology to evaluate the clinical tests for sensibility testing, determination of biomarkers and pulp bleeding with regard to their suitability to correctly diagnose the condition of the pulp tissue for the development of S3-Level guidelines.
METHODS
A literature search was conducted using PubMed, Clarivate Analytics' Web of Science, Scopus, Google Scholar and Cochrane Central Register of Controlled Trials from inception to 21 January 2022. Additionally, a hand search was performed, and the contents of the major subject journals were also examined. Eligibility criteria followed the proposed PICO questions. Two independent reviewers were involved in study selection, data extraction and appraising the included studies; disagreements were resolved by a third reviewer. The risk of bias was assessed by the QUADAS-2 tool for diagnostic accuracy studies, the Newcastle-Ottawa scale for noncomparative, nonrandomized studies and the Newcastle-Ottawa Quality Assessment scale adapted for cross-sectional studies.
RESULTS
In total, 28 studies out of 29 publications were considered eligible and were included in the review. Twelve studies were identified to investigate the diagnostic accuracy of the pulp vitality. Ten studies fulfilled the criteria to evaluate the diagnostic accuracy of the pulpal conditions, while 6 studies investigating the expression of biomarkers were eligible. Three studies addressing the prognostic factors and therapeutic interventions relating to pulpal status were included.
DISCUSSION
The core problem in pulp diagnostics is that a reliable reference standard is lacking under clinical conditions. Based on limited evidence, the most promising current approach seems to define a combination of different clinical tests and symptoms, probably in future including molecular diagnosis ("diagnostic package") will be required to ascertain the best possible strategy to clinically diagnose true pulpal conditions.
CONCLUSIONS
The effectiveness of diagnosing pulpitis is low due to limited scientific evidence regarding the accuracy and reproducibility of diagnostic tests. There is a lack of evidence to determine the true status of the pulp or to identify prognostic indicators allowing for a reliable pre-operative estimation of the outcome of vital pulp treatment.

International Endodontic Journal Jul 2022Incorporating an additive into lidocaine is a method to enhance the efficacy of the inferior alveolar nerve block (IANB) in mandibular posterior teeth. (Meta-Analysis)
Meta-Analysis Review
Anaesthetic efficacy of incorporating different additives into lidocaine for the inferior alveolar nerve block: A systematic review with meta-analysis and trial sequential analysis.
BACKGROUND
Incorporating an additive into lidocaine is a method to enhance the efficacy of the inferior alveolar nerve block (IANB) in mandibular posterior teeth.
OBJECTIVES
To assess the efficacy of incorporating additives into lidocaine in the success rate of IANB for teeth with the diagnosis of normal pulp (NP) or symptomatic irreversible pulpitis (SIP).
METHODS
Randomized controlled trials (RCTs) assessing the incorporation of additives into lidocaine on the pulpal anaesthesia success rate of mandibular posterior teeth were searched in PubMed, Scopus, Web of Science, Ovid, EBSCO, Embase, and Cochrane databases up to 1 December 2021. The risk of bias (RoB) was assessed by the Cochrane Risk of Bias Tool. A random-effects model was employed to calculate the pooled risk ratio (RR) with a 95% confidence interval (CI), using STATA 16. The trial sequential analysis (TSA) was applied to calculate the required information size (RIS). The Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach was used to assess the certainty of the evidence.
RESULTS
Of 6966 records retrieved initially, 14 trials (8 for NP and 6 for SIP groups) were included in qualitative and quantitative syntheses. All trials were categorized as low and unclear RoB for NP and SIP groups, respectively. In the NP group, with 307 participants, no significant effect was observed for additives incorporated into lidocaine (RR: 0.84; 95% CI: 0.53-1.32; I = 98%). Subgroup analysis revealed that adding mannitol led to a higher success rate (RR = 1.24; 95% CI: 1.15-1.34; I = 7.16%). In the SIP group, with 434 participants, no significant effect was shown when the additives were incorporated (RR = 1.22; 95% CI: 0.98-1.52; I = 0%). Likewise, in subgroup analysis, incorporating mannitol or sodium bicarbonate demonstrated no significant effect (RR = 1.76; 95% CI: 0.93-3.32; I = 18.41% and RR = 1.06; 95% CI: 0.65-1.72; I = 53.5%, respectively).
DISCUSSION
TSA revealed that the outcome was "inconclusive" for each group. The certainty of the evidence was graded as "very low" and "low" for NP and SIP groups, respectively.
CONCLUSIONS
The very low to low certainty of evidence indicated that incorporating additives into lidocaine did not increase the efficacy of IANB and supplemental injections are still necessary to help practitioners achieve painless dentistry.

Review
BACKGROUND
Inferior alveolar nerve block (IANB) is known to have a lower success rate for anesthesia in patients with irreversible pulpitis. This calls for supplementary techniques to effectively anesthetize such patients. This systematic review aimed to evaluate the published literature for determining the success rate of anesthesia induction using post-IANB intraligamentary (IL) injection in the mandibular teeth of patients with symptomatic irreversible pulpitis. The review question was, "What is the success rate of IL injection in the mandibular teeth of patients with irreversible pulpitis as a supplementary technique for endodontic treatment?"
METHODS
A thorough search of electronic databases and manual searches were performed. The protocol of the review was framed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist and was registered in the International Prospective Register of Ongoing Systematic Reviews (PROSPERO) with a proper criterion for inclusion and exclusion of studies. The included studies were analyzed using the Cochrane Collaboration ''Risk of Bias'' tool. A meta-analysis that included a comparison of primary nerve block and supplemental IL injection was performed. The success rate was evaluated using the combined risk ratio (RR) with a random risk model. A funnel plot was created to measure publication bias.
RESULTS
After all analyses, four studies were included. In the forest plot representation, RRs were 3.56 (95% CI: 2.86, 4.44), which were in favor of the supplemental IL injections. Statistical heterogeneity was found to be 0%. These values suggest that supplemental IL injections provide better success rates for anesthesia.
CONCLUSION
According to the pooled qualitative and quantitative analyses, supplemental IL injections increased anesthetic efficacy.

Review
Lipopolysaccharide (LPS) is widely used for induction of inflammation in various human tissues, including dental pulp. The purpose of this study was to summarize current medical literature focusing on (1) cell types used by researchers to simulate dental pulp inflammation, (2) LPS variants utilized in experimental settings and how these choices affect the findings. Our study was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). We searched for studies reporting outcomes of lipopolysaccharide application on dental pulp cells in vitro using electronic databases: MEDLINE, Web of Science and Scopus. Having gathered data from 115 papers, we aimed to present all known effects LPS has on different cell types present in dental pulp. We focused on specific receptors and particles that are involved in molecular pathways. Our review provides an essential foundation for further research using in vitro models of pulpitis.

AIM
The aim of this systematic review was to evaluate the clinical outcome of partial pulpotomy, pulpotomy and pulpectomy for treating primary teeth with normal or infected pulp or with irreversible pulpitis.
METHODS
Two reviewers on Pubmed and ISI Web of Science performed a comprehensive literature review of publications from 1966 until July 2019. Pico outline was used to facilitate literature research. Among abstracts, publications were selected according to the following criteria: prospective clinical study, correct indication for the performed treatment, clear definition of clinical and/or radiographic success criteria and at least 6-month follow-up period. The strict selection criteria under the keywords "pulpotomy", "partial pulpotomy" and "pulpectomy" resulted in a limited amount of randomised controlled trials (RCT) or controlled clinical trials (CT). Qualitative assessment of the selected clinical studies and level of evidence was included according to the criteria described by the Oxford Centre for Evidence-Based Medicine (CEBM).
CONCLUSION
Prerequisites for a successful pulpotomy are symptom-free teeth, sterile removal of coronal pulp and haemostasis. Both MTA and formocresol perform well for partial pulpotomies after caries exposure. Formocresol had been the most popular amputation material for pulpotomies. Due to the potential side effects, other medicaments, such as ferric sulfate, mineral trioxide aggregate (MTA) or NaOCl are suggested. Grey and white MTA yeld the same results. Lasers are not recommended due to their large diversity. Regarding pulpectomy, the conditions, procedures, and evaluation for the treatment were not well defined in the studies. Nevertheless, there is evidence to use calcium hydroxide, zinc oxide eugenol paste or iodoform based pastes as root filling materials for non-vital molars. Pulpectomies showed better success rates than pulpotomies. Stainless steel crowns are recommended as definite restorations after both endodontic treatments. Longer follow-up periods, further clinical studies with comparable conditions and clear definition of evaluation criteria are needed to further confirm the results of endodontic treatment in primary teeth.

Review
Several studies have linked apical periodontitis and systemic diseases. The aim of this study is to present a systematic review of the available literature investigating whether there is an association between pulpal-periapical pathology and autoimmune disease. The review was conducted following the PRISMA statement. A literature search was performed in five databases. Studies involving patients with pulpal-periapical pathology and autoimmune diseases were included in the review. Based on the PICO model, the research question aimed to assess whether there is an increased risk of developing pulpal-periapical pathology in patients with autoimmune disease. Article selection, data extraction, and quality assessment were performed using an adapted version of the STROBE guidelines. A total of seven studies were included in our review. The types of articles were five case-control and two cross-sectional studies. Periapical pathologies were associated to three autoimmune diseases (diabetes mellitus I, rheumatoid arthritis, and inflammatory bowel disease). Among the included studies, four show a low risk of bias, while three present a moderate risk. There could be an association between apical periodontitis and autoimmune diseases, although most studies report statistically non-significant associations.

Review
This systematic review aimed to assess the effect of premedication on postoperative pain after root canal treatment in vital teeth. Five electronic databases were searched for randomized clinical trials, and two independent reviewers selected eligible studies, extracted data, and assessed the quality of studies using the Cochrane Risk of Bias tool. Meta-analysis was conducted using the random-effects model, and the pooled effect estimate of the standardized mean difference (SMD) between premedication and placebo was calculated. Subgroup analysis was conducted based on the class and route of the drug. Studies with a high risk of bias were excluded from the sensitivity analysis. Ten trials satisfied the inclusion criteria, of which eight were included in the meta-analysis. Premedication was more effective in reducing postoperative pain than placebo at 6 hours (SMD = -1.00; 95% confidence interval [CI] = -1.33 to -0.66), 12 hours (SMD = -0.80; 95% CI = -1.05 to -0.56), and 24 hours (SMD = -0.72; 95% CI = -1.02 to -0.43). The results of the sensitivity analysis confirmed the findings of the primary analysis. Based on these results, it can be concluded that premedication is effective in reducing postoperative pain in teeth with irreversible pulpitis. However, additional quality studies are required for further validation.
