Let me try and settle this question in the most diplomatic way possible.
Dentistry, as any other human endeavor, is subject to very rapid technological developments. I can tell you that I diagnose, treatment plan, practice and execute procedures much differently than what was taught to me in Dental School over 15 years ago. In addition, many common opinions at that time have since been proven to be misguided and empirically based (someone's opinion) rather on science and statistics. We are getting better and better. Experience means very little these days without proper updates and continual educational/professional growth.
However, I can tell you that there are things that are constant: The human anatomy is the same, the healing response to injury and surgery is the same, and our response to bacterial insult is the same. Biology Does Not Change. What changes (and gets better) is our ability to diagnose, treat, and evaluate the long term outcomes of our treatment. Hence, certain "traditional" therapies have been proven effective, and some were proven to be less effective and have been dropped from treatment protocols. The problem with new technology is that long-term data is not available. This is why most educated professionals tend NOT to "jump" on a new procedure, but wait for some data to accumulate.
LANAP is only but one of many, technology based, treatment modalities. The data is very favorable and is pouring in. Few periodontists have incorporated LANAP into their practice. It is very expensive technology (the laser costs tens of thousand of dollars). The higher end practices can afford it, but their patients are ready to foot the bill. Unfortunately there are dentists out there who advertise TECHNOLOGY as the solution to all problems. The LANAP technology is best performed by a trained Periodontist as it is just another procedure, and required the dentist to have the same advanced education as it is to perform the more traditional surgical modalities. Ultimately IT IS NOT THE TECHNOLOGY, but WHAT YOU DO WITH IT, the counts. Forget about the technology itself and concentrate on finding the BEST trained Periodontist and the one with whom you are most comfortable. Then go with his/her advise. You MUST ask about the LANAP technology, but if you trust the Periodontist and he/she is uncomfortable with the technology and are comfortable delivering more "traditional" established methods, go with his/her recommendations. I personally prefer a more traditional method with a trained professional, than the newest technology with a less trained, doctor.
www.perio.org will have a link to locating a trained Periodontist near you. You might want to go for a second opinion.
