Introduction: Implant dentistry is currently being revolutionized by breakthroughs in techniques, technology, and material, there are few systematic reviews and meta-analyses that examine the effects of utilizing different bone graft substitutes in immediate implant placement surgeries.
Aim: The purpose of this research is to systematically review and meta-analyze the effect that different bone graft substitutes have on implant stability when concurrently utilized in patients undergoing immediate implant surgeries.
Methodology: The PICO criteria were used to construct the focused question, and the systematic review has been outlined as per the PRISMA guidelines. The revised Cochrane risk-of-bias method for randomized trials was used to assess the risk of bias for the selected articles. To derive estimates for the results, random effects meta-analysis was conducted on the selected articles.
Results: The electronic databases were searched and a total of 1583 articles were identified. After title and abstract screening and due to problems in retrieval a further 1358 articles were eliminated. Fifteen articles were finally chosen to be qualified for review. Of which full text evaluation of 5 articles were found to meet the eligibility criteria and were therefore included in the systematic review.
Conclusion: This systematic review and meta-analysis on the stability of dental implants and bone graft substitutes in immediate implant surgery, was unable to draw any conclusions and established no statistically significant correlation between the different types of grafts used and implant stability.
Objective: Evidence suggests that lipocalin-2 (LCN-2), a bone-derived protein, is upregulated in periodontal diseases. This systematic review aimed to evaluate LCN-2 concentrations in individuals with periodontal diseases, identifying the most suitable body fluids for its detection, the type of periodontal disease with the highest LCN-2 expression, its association with other inflammatory markers and systemic diseases, and whether its expression can be modified by periodontal treatment.
Methods: A systematic search of Google Scholar, PubMed, and ProQuest up to August 2024 was conducted. The studies were screened and selected by the authors according to specific eligibility criteria. Quality assessment of the included studies was performed according to the study type using STROBE statement for observational studies or the modified Jadad scale for experimental studies. The review was registered in PROSPERO (CRD42023458565).
Results: In total, three thousand six hundred and thirty-eight reports were identified, of which twenty-seven were full-text assessed for eligibility, including eleven articles. Seven articles were observational, and four were experimental. Significantly elevated LCN-2 levels were reported in patients with periodontal disease across 9 studies, being higher in periodontitis rather than gingivitis. LCN-2 was mainly detected in gingival crevicular fluid (GCF) and saliva. LCN-2 expression is related to the increment of inflammatory markers, and periodontal therapy decreases LCN-2 concentrations. LCN-2 levels were aggravated when periodontitis was accompanied by obesity and type 2 diabetes.
Conclusion: LCN-2 is implicated in periodontal diseases, probably through the inflammation process.
Objective: The study aims to compare the effectiveness of behavioural therapy and inhalational sedation in reducing dental anxiety among patients visiting dental clinics.
Methods: A search was conducted in PubMed, Cochrane databases, Scopus, and Google scholar through August 2024. All the randomized control trials, cohort studies, case control, cross-sectional studies that evaluated the effectiveness of behavioural therapy with inhalational/conscious sedation among children and adults to reduce dental anxiety were included. Outcome assessed was change in the dental anxiety scores as measured by the validated tools. PRISMA guidelines were followed for the meta-analysis. Meta-analysis was conducted using Cochrane Review Manager (Revman) version 5.3. Random effects model was used to compare the two groups in reducing dental anxiety. Quality of the studies included was evaluated using the Risk of Bias Assessment tool and Newcastle-Ottawa tool. Heterogeneity was assessed using I2 values. Certainty of evidence was assessed using GRADE pro software. The protocol was registered in PROSPERO (CRD-NIHR) database with Reference ID CRD42024581013.
Results: A total of 940 participants were included in the analysis. Behavioural therapy was significantly more effective than inhalational sedation in reducing dental anxiety among patients prior to the dental treatment (SMD: -0.87; 95% CI: -1.29 to -0.45; P < 0.0001; I2:78%). Additionally, behavioural therapy demonstrated more effectiveness than inhalational sedation in reducing the dental anxiety among children (SMD: -0.64; 95% CI: -1.16 to -0.11, P = 0.02%; I2:88%). Certainty of evidence was high among the randomized controlled trials and moderate among the observational studies.
Conclusion: The findings of this review and meta-analysis suggests that behavioural therapy is more effective than inhalational sedation in reducing dental anxiety specifically among children.
Aims/objectives: Biomechanical preparation (BMP) of primary teeth often involves using hand and rotary instruments. This study aimed to assess the effectiveness of hand and rotary instruments during BMP in primary teeth.
Methods: A thorough search for relevant systematic reviews and meta-analyses (SRMAs) was conducted in four databases, including MEDLINE, EMBASE, Google Scholar, and the Cochrane Library. The primary outcome assessed was the instrumentation time (IT) for BMP, and the identified SRMAs were qualitatively analysed using the ROBIS tool. Furthermore, quantitative analysis, evidence stratification, and GRADE analysis of eligible SRMAs were performed using the browser-based R package metaumbrella software.
Results: Six SRMAs addressing the research question were included, with five being evaluated as having a high risk of bias (ROB). The findings indicated that the IT required for BMP in primary teeth was 3.2 min less (95% CI = 1.52 to 4.93; I2 = 96%; P = < 0.001) using rotary instruments compared to hand instruments, with a 'class IV' evidence stratification and 'very low' class of evidence.
Conclusions: Based on the existing evidence, it can be inferred that there is insufficient quality data to recommend the use of rotary instruments over hand instruments in primary teeth.
Purpose: Digital dentistry provides an alternative to fabrication of crowns. This systematic review focuses on the accuracy of the mean internal space of lithium disilicate crowns when comparing intraoral scanning to conventional impressions.
Methods: Ovid Medline, Cochrane and PUBMED were searched and the review protocol followed the International Prospective Register of Systematic Reviews (PROSPERO) (CRD42023379908) and guided by The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Cohen Kappa coefficient confirmed the agreement of data. The revised Cochrane Risk of Bias tool was utilised to evaluate randomised controlled trials The Methodological Index for non-randomised controlled trials.
Results: Of the six in vivo studies, three concluded that digital techniques improved the internal fit over their conventional counterparts. Two found that there was no significant difference and one indicated that digital technique resulted in an inferior internal fit. Of the eight in vitro studies, two concluded digital techniques to be superior, two found digital techniques to be inferior and four found no significant difference.
Conclusion: Significant heterogeneity between studies limits the potential any systematic review of the internal fit of dental crowns when comparing conventional and optical impressions. This systematic review indicates digital methodology is comparable to that of conventional impressions.
