Mickey,
I think you can be pretty sure that in 8 weeks there is not new attachment so what is really happening in this case? I think time will tell what you really have happening with this treatment.  Do you have any measurements regarding attachment level ? Do you know if you’ve lost any tissue? What was the cause of the pocket (periodontitis vs. perio abcess)? Answers to these may give us all more insight into what has really happened here.

My big concern is always heat inside a pocket with the erbium. Take your 1W 0/0 and aim it at your finger and see how close you can come w/o discomfort. Feel how deeply the heat penetrates. Now imagine that same thing closed in on each side (bone, soft tissue, etc around the tip in the pocket). Possibly by being only 1 mm in the pocket, the distance to the target was great enough to decrease the power density. Maybe you were able to prevent thermal damage because the treatment time was also short enough. It seems though that, that, is a mighty fine line to walk.

Glad to hear it seems to be working for your patient,

Mickey look for a vertical root fracture or a perf (was endo done on the tooth) in the mid buccal area if this is the only area with a vertical defect.

You got repair by recession and a reduction in inflammation. The laser may have had little to do with it. It may also rebound-you treated it a ton of times in a short period of time, you didn’t regrow anything.
