Meta-Analysis
INTRODUCTION
Dental implants are a common solution for edentulous patients. This systematic review and meta-analysis aimed to determine whether locally delivered diphosphonates influence the osseointegration of dental implants in humans.
MATERIAL & METHODS
In March 2023, we conducted an electronic systematic literature search using three databases (MEDLINE/PubMed, Embase, Web of Science). We included randomized trials documenting locally delivered diphosphonates in partly edentulous patients. Two independent reviewers evaluated study eligibility, extracted data, and assessed study quality.
RESULTS
We have identified 752 studies, out of which 7 studies involving 154 patients met the inclusion criteria. The overall meta-analysis indicates that diphosphonates are associated with marginal bone loss during the pre-loading period (mean difference (MD) of -0.18 mm, 95% CI -0.24 to -0.12, p<0.00001; I²=83%), marginal bone loss after one year (MD -0.35 mm, 95% CI -0.56 to -0.14, p = 0.0009; I²=14%), and five years loading (MD -0.34 mm, 95% CI -0.56 to -0.13, p = 0.002; I²=0%). However, the drug did not seem to affect the implant survival rate (risk ratios (RR) of 1.02, 95% CI 0.98 to 1.08, P = 0.33; I²=9%).
DISCUSSION
This study suggests that local use of diphosphonates does not affect implant survival, but it does reduce marginal bone loss and improve the osseointegration of dental implants in humans. However, future research must be more standardized and address methodological biases to draw more conclusive findings.

Review
INTRODUCTION
Prosthetic joint infection (PJI) is a destructive complication of knee replacement surgery (KR). In two-stage revision a spacer is required to maintain limb length and alignment and provide a stable limb on which to mobilise. Spacers may be articulating or static with the gold standard spacer yet to be defined. The aims of this scoping review were to summarise the types of static spacer used to treat PJI after KR, their indications for use and early complication rates.
METHODS
We conducted a scoping review based on the Joanna Briggs Institute's "JBI Manual for Evidence Synthesis" Scoping review reported following Preferred Reporting Items for Systematic Review and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) checklist. MEDLINE, EMBASE and CINAHL were searched from 2005 to 2022 for studies on the use of static spacers for PJI after KR.
RESULTS
41 studies (1230 patients/knees) were identified describing 42 static spacer constructs. Twenty-three (23/42 [54.2%]) incorporated cement augmented with metalwork, while nineteen (19/42, [45.9%]) were made of cement alone. Spacers were most frequently anchored in the diaphysis (22/42, [53.3%]), particularly in the setting of extensive bone loss (mean AORI Type = F3/T3; 11/15 studies 78.3% diaphyseal anchoring). 7.1% (79 of 1117 knees) of static spacers had a complication requiring further surgery prior to planned second stage with the most common complication being infection (86.1%).
CONCLUSIONS
This study has summarised the large variety in static spacer constructs used for staged revision KR for PJI. Static spacers were associated with a high risk of complications and further work in this area is required to improve the quality of care in this vulnerable group.

Review
CONTEXT
Office-based treatments are increasingly offered as an optional step to replace medical treatment or delay surgery for male lower urinary tract symptoms (LUTS). Nevertheless, little is known regarding the risks of retreatment.
OBJECTIVE
To systematically evaluate the current evidence regarding retreatment rates after water vapor thermal therapy (WVTT), prostatic urethral lift (PUL), and temporarily implanted nitinol device (iTIND) procedures.
EVIDENCE ACQUISITION
A literature search was conducted up to June 2022 using the PubMed/Medline, Embase, and Web of Science databases. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed to identify eligible studies. The primary outcomes were the rates of pharmacologic and surgical retreatment during follow-up.
EVIDENCE SYNTHESIS
A total of 36 studies including 6380 patients met our inclusion criteria. Surgical and minimally invasive retreatment rates were generally well reported in the studies included and reached up to 5% after 3 yr of follow-up for iTIND, and up to 4% for WVTT and 13% for PUL after 5 yr of follow-up. The types and rates of pharmacologic retreatment are poorly reported in the literature, with the latter reaching up to 7% after 3 yr of follow-up for iTIND, and up to 11% after 5 yr of follow-up for WVTT and PUL. The main limitations of our review are the unclear to high risk of bias in most of the studies included and the lack of long-term (>5 yr) data on retreatment risks.
CONCLUSIONS
Our results highlight the low retreatment rates at mid-term follow-up after office-based treatments for LUTS, supporting the development of these strategies as an intermediate step between BPH medication and conventional surgery. Pending more robust data with longer follow-up, these results should be used to improve patient information and facilitate shared decision-making.
PATIENT SUMMARY
Our review highlights the low risk of mid-term retreatment after office-based treatments for benign enlargement of the prostate that is affecting urinary function. For well-selected patients, these results support the increasing use of office-based treatment as an intermediate option before conventional surgery.

Meta-Analysis
Clinical, Radiographic, and Histologic Outcomes of Regenerative Endodontic Treatment in Human Immature Teeth Using Different Biological Scaffolds: A Systematic Review and Meta-analysis.
BACKGROUND
Biological scaffolds such as blood clot (BC), platelet-rich plasma (PRP), platelet- rich fibrin (PRF), and platelet pellet (PP) are used in regenerative endodontic treatments (RETs).
OBJECTIVE
To systematically and quantitatively evaluate clinical, radiographic, and histologic outcomes of RET studies using different biological scaffolds.
METHODS
MEDLINE, Scopus, Cochrane library, and Embase were searched to identify studies on RET procedures with any scaffold type performed on immature non-vital human teeth, employing any type of biological scaffold. Clinical, radiographic, and histologic outcomes were extracted. Cochrane collaboration risk of bias tool and Newcastle-Ottawa scale were used for quality assessment. Random and fixed model meta-analysis was carried out with 95% confidence interval.
RESULTS
Thirty-two studies were included in the qualitative analysis from the primarily retrieved 1895 studies. Only one study had high risk of bias and 71.8% of the studies had high quality. None of the studies reported any histologic findings. Thirty studies were included in meta-analysis. Clinical success rate of RET using either BC, PRP, or PRF was >99%. Furthermore, 32%, 23%, and 27% of BC, PRP, and PRF cases regained vitality, respectively. Periapical healing was seen in 67%, 75%, and 100% of BC, PRP, and PRF cases, respectively. There was no statistical difference between BC, PRP, or PRF regarding clinical success or any radiographic outcomes.
CONCLUSION
There was no significant difference between BC, PRP, and PRF in terms of clinical and radiographic outcomes. When it is difficult or dangerous to induce bleeding in root canals, PRP and PRF may be employed instead.

INTRODUCTION
The concept of bioresorbable scaffolds (BRS) was born with the aim to reduce the rate of late and very late cardiac events related to drug-eluting stents. However, first-generation BRS failed to prove their short-term safety and efficacy. Based on data derived from early investigations, new-generation BRS have been developed and tested in preliminary studies. The present review's focus was to summarize the mechanical characteristics of these new scaffolds and the clinical evidence of their safety and efficacy.
EVIDENCE ACQUISITION
This systematic review was performed following Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA). PUBMED, Google Scholar, and Biomed central databases were analyzed. Only papers published in English and in peer-reviewed journals were selected to summarize current evidence about new generation BRS, with CE mark approval. Overall, 23 studies were included.
EVIDENCE SYNTHESIS
Data obtained from selected studies assessing the safety and efficacy of new generation BRS are encouraging. This is thanks to the progressive development of scaffolds with a different backbone structure and struts thickness that guarantee higher radial strength, flexibility, and resistance to fracture. These characteristics led to low rates of major adverse cardiac events and device-oriented composite endpoint at follow-up.
CONCLUSIONS
New-generation BRS have a good safety profile in stable patients with simple lesions, supported by a meticulous implantation technique. The first studies were performed on a small population with short-term follow-up, therefore new randomized clinical trials and registries are needed to expand the preliminary findings.
