Background
Many clinical studies have evaluated the role of biochemical mediators like insulin-like growth factor 1 (IGF-1) in assessment of skeletal maturity. But still the reliability of IGF‑1 as ...an indicator of skeletal maturity remains controversial.
Objective
To assess the correlation between IGF‑1 and different radiographic skeletal maturity indicators.
Search methods
Seven electronic databases (PubMed, Scopus, EMBASE, Medline, Cochrane CENTRAL, Web of Science and SciELO) were searched until January 2020 without any restriction based on language or date of publication.
Selection criteria
The study design included cross-sectional and longitudinal studies comparing IGF‑1 and other skeletal maturity indicators (SMIs).
Data collection and analysis
Data extraction was done by two reviewers independently; 15 studies were eligible to be included in the quantitative synthesis.
Results
There was significant positive correlation between IGF‑1 and different SMIs until puberty which was 0.95 (confidence interval CI = 0.89, 1.02) for males and 0.87 (CI = 0.77, 0.97) for females. A negative correlation between IGF‑1 and different SMIs was found after puberty which was −0.86 (CI = −0.97, −0.75) for males and −0.89 (CI = −0.98, −0.81) for females. The type of SMI compared and type of IGF‑1 sample used accounted for the high heterogeneity found across the studies. Chronological age and number of months passed after puberty showed moderate negative correlation with mean IGF‑1 levels which were −0.57 (CI = −0.67, −0.47) and −0.54 (CI = −0.66, −0.42). Annual increments in mandibular length showed significant positive correlation of 0.69 (CI = 0.48, 0.90).
Conclusions
IGF‑1 would serve as a promising alternative to conventional radiographic skeletal maturity indicators and in predicting the amount of residual mandibular growth.
Introduction: Genetic polymorphisms of genes regulating amelogenesis can alter susceptibility to Early Childhood Caries (ECC). This systematic review aims to analyze associations between ...single-nucleotide polymorphisms of enamel formation genes and ECC. Methods: Search was conducted across PUBMED, CINAHL, LILACS, SCOPUS, EMBASE, Web of Science, Genome-Wide Association Studies databases from January 2003 to September 2022. This was supplemented by hand search. Totally 7124 articles were identified and 21 articles that satisfied the inclusion criteria proceeded to data extraction. Quality assessment was done using the Q-Genie tool. Results: Quantitative synthesis revealed that homozygous genotype AA of rs12640848 was significantly higher in children with ECC with an odds ratio of 2.36. Gene-based analysis revealed significant association between six variants of AMBN, four variants of KLK4, two variants of MMP20, and a single variant of each of MMP9 and MMP13 genes and ECC. The Bonferroni corrected-log10 P value of amelogenesis gene Cluster was 2.25 (0.05/88 = 5.6 × 10−4). Search Tool for Retrieval of Interacting Genes and Proteins plot constructed to comprehend the protein-protein interaction revealed the presence of four functional clusters. Gene function prediction using Multiple Association Network Integration Algorithm revealed that physical interaction between these genes was 69.3%. Conclusion: Polymorphisms of genes regulating amelogenesis can influence the susceptibility to ECC. AA genotype of rs12640848 may increase the susceptibility to ECC. Gene-based analysis revealed a significant association between multiple polymorphisms of genes regulating amelogenesis and ECC.
The purpose of this review was to determine the diagnostic accuracy of cone-beam computed tomographic (CBCT) imaging in detecting vertical root fractures (VRFs) in root-filled teeth compared with a ...reference standard (direct visualization).
Electronic searches were performed in Medline, Scopus, Cochrane, and gray literature for English language articles until June 2020. Prospective and retrospective clinical studies using CBCT imaging to diagnose VRFs in root-filled teeth were included. Case reports and in vitro studies were excluded. The Quality Assessment of Diagnostic Accuracy Studies 2 tool was used to assess the risk of bias and applicability concerns. Meta-analysis was performed using Stata 16.1 software (StataCorp, College Station, TX) via the MIDAS v.3.0 package and METANDI module. Publication bias was evaluated using Deeks’ funnel plot analysis. Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) was performed to evaluate the certainty of evidence. This systematic review was registered in the Open Science Framework (10.17605/OSF.IO/7JKE2).
Eight articles were included in this systematic review and meta-analysis. Risk of bias assessment showed that 5 articles in the patient selection domain had low risk of bias with low applicability concern. In the index test and reference standard domains, 7 articles had moderate risk of bias with moderate applicability concern. Three articles had high RB in the flow and timing domain. There was no publication bias. CBCT imaging had a pooled sensitivity and specificity of 0.78 (95% confidence interval CI, 0.64–0.88) and 0.80 (95% CI, 0.63–0.91), respectively, and an accuracy of 0.86 (95% CI, 0.83–0.89). CBCT imaging also had pooled positive and negative likelihood ratios of 4 and 0.2, respectively. In GRADE analysis, the quality of evidence was low for sensitivity and moderate for specificity when CBCT imaging was used for the diagnosis of VRF.
The overall quality assessment of the included articles showed that in the patient selection domain, the risk of bias was low, and it was moderate in the index test and reference standard domains. Evidence from this systematic review and meta-analysis indicates that CBCT imaging is still not a good tool for diagnosing VRFs in root-filled teeth compared with direct visualization.
•There exists a necessity to perform a systematic review and meta-analysis to determine the association between pulp calcification (PC) and cardiovascular disease (CVD) since there is a lack of ...consensus in literature regarding their association.•Based on the current literature, the certainty of evidence is low to prove the association between PC and CVD.•Further longitudinal studies with a larger sample size need to be performed; and the criteria for the selection of CVD patient needs to be uniform and standardized.
This systematic review and meta-analysis was performed to evaluate the association between pulp calcifications (PC) and cardiovascular disease (CVD).
Five databases (PubMed, Scopus, Embase, Web of Science and ProQuest) were searched to identify articles. Quality assessment of the selected articles was done using Joanna Briggs Institute critical appraisal tool and the inter-examiner agreement was calculated using the Cohen-Kappa test. The random-effects maximum likelihood model was used to evaluate the association between the conditions. Trim-and-fill funnel plot was used to evaluate the presence of publication bias. The level of evidence was evaluated using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) tool.
A total of 2487 articles were identified from the initial search. Ten articles were included in this review of which 7 were cross-sectional and 3 were case-control studies. Eight articles had a low risk of bias (RoB), one article each had a moderate and high RoB. Inter-examiner reliability score was 0.8592. Seven articles reported a statistically significant positive association between CVD patients and PC. Two articles reported a non-significant positive association and one article reported no association between the same. A significant difference was observed in favor of CVD patients to possess more PC in comparison to non-CVD patients with an OR of 4.30 (95% confidence interval (CI): 2.19, 8.46; p = .000). Asymmetry in the Trim-and-fill funnel Plot suggested the presence of publication bias. GRADE analysis demonstrated low certainty of the evidence for the overall sample.
There exists a low level of evidence to show that CVD patients are more prone to have PC in comparison to non-CVD patients.
Aim The aim of this systematic review and network meta-analysis was to identify the best irrigant activation technique (IAT) for the removal of accumulated hard tissue debris (AHTD) from the mesial ...root of mandibular molars evaluated using micro-CT studies.Methods The research question was based on the PICO format. Four electronic databases - PubMed, Scopus, Embase and Web of Science - were searched for articles up to June 2020. Selected articles were assessed for bias using the Joanna Briggs Institute Critical appraisal tool. The network meta-analysis using a fixed-effects model and SUCRA ranking were performed. The quality of the evidence was assessed using the CINeMA framework.Results Eleven studies were included for qualitative synthesis while seven were included for quantitative synthesis. The risk of bias of all included articles was low. The results based on SUCRA values revealed the IAT shock wave-enhanced emission photoacoustic streaming (100%) resulted in the greatest reduction of the volume of AHTD from mesial roots of mandibular molars. Ranking of the other IATs was as follows: photon-induced photoacoustic streaming (87%), laser-activated irrigation (79.3%), XP EndoFinisher (71.2%), ultrasonically activated irrigation (59.6%), apical negative pressure (42.3%), EasyClean (37.4%), EDDY (26.2%), EndoActivator (24.2%), self-adjusting file (11.6%) and needle irrigation (11.3%).Conclusion None of the IATs rendered the root canals completely free of AHTD. The laser-activated irrigation groups fared better than all other interventions in reducing AHTD from the mesial roots of mandibular molars. The confidence rating ranged from low to high for indirect evidence and moderate to high for mixed evidence. Results must be interpreted with caution due to the laboratory nature of the included studies.
The aim of this systematic review was to assess the antimicrobial activity of nanoparticle-mediated photodynamic therapy (N-PDT) on
biofilms in the presence of dentin substrate when compared to ...photodynamic therapy (PDT) and conventional disinfection protocols.
This systematic review was registered in Open Science Framework (10.17605/OSF.IO/GBR3F). Six databases, namely PubMed, Embase, Web of Science, Scopus, Medline, and Google Scholar, were searched for English language articles until June 2022. Laboratory studies assessing the antimicrobial activity of N-PDT against
biofilm in human or bovine teeth were included. The risk of bias (RoB) was evaluated using the Joanna Briggs Institute tool for quasi-experimental studies. Meta-analysis was performed using the random-effects maximum likelihood model.
The search revealed 2804 articles, out of which 9 studies were included in the final review. Seven articles had low RoB and two had moderate RoB. Chitosan and diode laser at 810 nm were the most commonly used nanoparticle and light source, respectively. The meta-analysis of bacterial reduction log and percentage reduction revealed that N-PDT had better antimicrobial efficacy than the control group. When the bacterial reduction log of N-PDT was compared with PDT, PDT performed better N-PDT, and for percentage reduction, there was no difference.
The currently available evidence is low and inconclusive with regard to the superior efficacy of N-PDT. The type of nanoparticle, incubation time, light source, and exposure time were found to be covariates that influence the antimicrobial efficacy of N-PDT.
