Issues with Chlorhexidine and effects in gingival tissue and implants

Quick question. I had a rep come in to my office to look at one of our machines for software updates and she mentioned something regarding the effects and concerns regarding chlorhexidine and soft tissue complications, fluoride varnish and concerns regarding its ability to decrease the longevity of implants due to corrosion of the first layer of the crown. I am unable to find anything on google scholar and studies. Does anyone know where I can find this information?

When I do a Google search, I search what I’m looking for with “scholarly articles” added. For instance, “Chlorhexidine inhibition of fibroblasts scholarly articles.” You can always ask the rep for research backing up her recommendations.
With this said, the rep is correct. Chlorhexidine inhibits the reattachment of fibroblasts, essentially inhibiting healing. This is why it’s intended use is for gingivitis, not treatment that reattachment is the goal. Here are some studies:

As far as fluoride varnish and it’s corrosion risk to an implant, I believe there’s only a couple of studies on this. I reached out to a friend of mine, implant expert Michelle Strange, and she said, “If a patient has exposed threads and multiple areas of decay and high risk for more decay then I will probably put on the fluoride because the patient has multiple areas that need to be cared for. If threads are not exposed and they’re low carries risk, I would probably error on the side of caution with placing the fluoride because it could do some damage.”
