Conclusion: Platelet-rich fibrin and chlorhexidine 0.2% gel had a large number of included studies and patients per comparison. Overall, there was moderate evidence to support the use of platelet-rich fibrin or chlorhexidine 0.2% gel in the socket for the prevention of AO after mandibular third molar surgery.
PubMed 32718882 ↗Colloidal Silver
The short answer. There isn't much data on Colloidal Silver yet — 6 mentions, 5 with a clear outcome — so treat these numbers as anecdotal. There is a moderate body of research — 4 meta-analyses and 4 trials.
From 6 mentions in total — the rest didn't say how it went and aren't counted.

What the research says
Systematic reviews and meta-analyses from PubMed, with their published conclusions.
At least one meta-analysis, or 5+ randomized controlled trials. The grade measures how much human research exists — read the conclusions below for what it found.
Conclusion: It is expected that the antibacterial property of bulk silver is carried over and perhaps enhanced, to silver nanoparticles. Therefore, when one examines the environmental issues associated with the manufacture and use of silver nanoparticle-based products, the antibacterial effects should always be taken into account particularly at the different stages of the product lifecycle. Currently, there are two arguments in the scientific literature about the mechanisms of antimicrobial properties of silver nanoparticles as they relate to colloidal silver particles and inonic silver.

PubMed 19945151 ↗Conclusion: The possibility of NSD in the wound healing time being the best treatment was 75.2%, followed by SID (36.6%), and finally SSD (1.1%); and the possibility of NSD being the best relieving the pain was 83.5%; followed by SID (60.0%), and finally SSD (16.3%). According to the evidence, treatment for burns with NSD can improve the wound healing time and relieve the pain of wounds.
PubMed 33909511 ↗Conclusion: With the available evidence it is not possible to be definitive about risks to human health from oral exposure to silver particulates. However, the balance of evidence suggests that there should be concerns especially when considering the evidence from jewellery workers. There is an urgent need to determine whether people exposed to particulate silver as part of drinking water treatment have evidence of DNA damage.
