Effects of water flow on dental hard tissue ablation using Er:YAG laser.

CONCLUSION: Effective ablation of dental hard tissue using Er:YAG laser requires that the appropriate water flow rate correspond properly to irradiation conditions. The results of this study suggest the following parameters; a water flow rate of 1.69 mL/min for enamel and dentin ablation at a pulse energy of 250 mJ and for dentin ablation at 400 mJ/pulse, and a water flow rate of 6.75 mL/min for enamel ablation at a pulse energy of 400 mJ, regardles] s of pulse repetition rate of 5, 10, and 20 Hz.

In addition I had asked Keith Bateman to send me studies supportiing HK.

He twice said that he would long ago in October by phone and by email.

I never received them. The chapter is due January 15th , and I will go with what I have now as I had told Keith twice that the deadline was November 15th, and he had originally told me to write the chapter without including the Er,Cr:YSGG because they were a unique wavelength and insinuated they werent a part of the erbium laser family.

I dont want to get snitty about it but I asked diplomatically of both Keith and Jeff at the ADA, and both declined as they said that given my background I was unlikely to be fair in my assessment of them.

It was afterwards that Keith said he would help me out. I am of course disappointed that Keith didnt live up to his word and at least send me the articles he claimed he would.

The chapter is now half written and its a little late for me to go back and change it all around.

I hope this helps you.

Thanks Ray: I wanted people to know that I tried to present as good a chapter as I can given the fact that I am a clinician and not a researcher so its tough for me to interpret all the research that is out there.

I am doubtful that ever there will be complete closure to this issue and in addition I believe in my heart that whatever happens for one wavelength happens very similar to another in the erbium family. I have never believed that it magically happens to a huge extent for one compared to the other.

Finally Ray I wanted you to know that I tried darn hard to get the proper papers for statements that certain companies have made regarding their product, to substantiate these.

I was promised that papers would arrive. I tried to go to a lecture to hear it from a gurus own mouth as to how it works. I was denied entrance to the lecture even after I was officially invited by the speaker.

I have toned down my remarks in all forums but when people do read the chapter I hope that there is recognition of a few main points.

1. I tried to be even handed in my representation.
2. I am primarily a clinician who knows pretty well the pros and cons of using the product.
3. I tried to educate people as to what the laser can do given the restrictions of publishing a scientific look at all hard tissue lasers.

Hope that helps.

Take care and again, sorry if I seemed snitty but the lack of cooperation of certain individuals really should be apparent so that I am not crucified for not giving both sides of the story…….when in all honesty all I got was one side.

All the best and happy new year and its gonna be a good year for all the laser companies and lasers are a real buzz word in the dental field these days.
