Glenn van AsSpectatorBob I will say that you must be careful with the Continuum tips as they will degrade ( the old ones at least) in the bleach. I know because I did it and they had an aluminum coating and that broke down in the bleach as I saw little silver flakes in the tooth under the scope in the pulp chamber.
I still use bleach but not with the laser.
I use vertical condensation with Kerr EWT like Cliff as well.
We use the System B for downpack and the Obtura 2 for back fill.
I also use the erbium but not for shaping, more for cleaning and disinfecting.
Z2 and Z3 is 200 and 300 micron or #20 and #30 files I would imagine.
Nice result and mark here is the final fill adjusted in the ACDSee program.
Thanks for the interesting case…….cool stuff.
Glenn
I dont know if I am ready to shape totally the canal with the laser yet.
Buchanan says you need 30-45 mins for bleach in cases and I wonder if the laser will allow you to do them differently and faster in certain cases.
I think the Nd Yag, diode, argon etc can be used with bleach to warm it up without fear of problems but be careful with the Bleach with the erbium…….I know like I said because I did it and saw the breakdown. I dont know what kind of coating there is on the Waterlase tips so cant make a suggestion.
I concur with Mark……..only lase on the upstroke. I have had bleeding coming out of the canal after using the laser on the down stroke because it went through the apex and guess what…….My apex was enlarged.
i stay 2-3 mm from the end and lift out at around 2 mm per second and use it in the canals for around 30 secs per canal.
Cool stuff Mark.

Quote:Glenn, thanks for the nice remarks. The radiograph you copied looks great, except it’s the initial apical working length files, not the fill, but that’s ok, I get your drift.
I have read studies that show you don’t have to use Buchannan’s 30-45 min bleach technique when using the laser because of how the smear layer is removed. I will try to find it and post it, or at least it’s source (the study that is).
And yes, the tips are 200-300 micron respectively. The Z-3 is concurrent with a 30-35 file in most cases, depending on how many times you activate the laser to enlarge the canals.
All I know is, it IS faster, easier, and my final results are better than ever. Just after dental school, I practiced in a large general practice and for 2 years I did almost nothing but the endo for everyone. I studied at that time with the endodontist next door, Dr. Marshall Smulson, who was the chairman of endo at Loyola, also where I taught in the Operative dept. I do a ton of it, and feel I have been taught, especially those 2 years after dental school, by one of the original masters. That being said, it is one of my strong points I believe in my daily practice routine, and so far, my results have been excellent. Now with the laser, it has gotten even better. Has anyone seen the SEM’s of the canal walls after exposure to Erbium laser energy? If not, I will try and post them here. Once I saw the comparisons, to the Profile Crown Down technique, the K File step back technique, and the YSGG Step back technique, I won’t do another endodontic procedure without the laser, if possible. I really do believe in what I am seeing thus far, and have done MANY cases. I am NOT an endodontist by any means, but seriously, I can’t believe the results after using the laser, in post op sensitivity (lack thereof), better fills, relieving infection, and inflamation. Amazing so far. That is my take on it. Thanks for letting me share this with you all. I hope, Glenn, you try it, enlarging that is. Let me know how you do. You guys are great, thanks for the replies!
Sincerely,
Mark
whitertthSpectatori used my waterlase at .75 watt no air or water…. she seemd to have a very high recurrence rate of all her ulcers…..
whitertthSpectatormark great stuff….how long did the crown lengthening take? also i see pretty good hemostasis…is that a kodak moment or did u have good hemostasis throughout? Hope your jumpshot is well….
smileagainSpectatorI will be using my Waterlase for endo very shortly, because I will be visiting Bill Chen’s office this weekend to learn more about the technique.
We have all had that hot nerve fiber that we are unable to anesthetize- no matter what. To solve this problem I place a cotton ball covered with topical anesth directly in the pulp chamber for @ 60 sec. then I am able to do a direct pulpal injection with no feeling 90% of the time- and the 10% is just a small “bee sting.” This has saved me many hours and saved the patient from any discomfort.Jerry Rosenfeld, DDS
2thlaserSpectatorHey Ron. The crown lengthening took about 7 minutes. Not long at all. The hemostasis WAS good. Usually I get a little bit of bleeding, that I like. I will let it sit for about 5 min, let the patient bathe it in saliva, by then, it’s stopped, and I am ready for impression, build up, whatever is next. I have been lecturing so much, I haven’t played bball in over 2 months, so you would be able to pass through me like MJ at 23 y/o! BUT, that’s gonna change! SOON! Thanks.

jetsfanSpectatorMark,
Once again , fantastic job.
For the endo, my preference is CRCS endo sealer. It is a calcium hydroxide type sealer. One of the endo guru’s recommended it at a meeting I attended. Maybe it’s me but,
Don’t you think it would be helpful if there was some type of color on the handles of the Z3 and Z4 endo tips. Even with my 4x loupes it is sometimes difficult to distinguish between them.
Glenn van AsSpectatorThanks Jetsfan…….I will ask my front office team about whether they have had problems with this or not.
Great point and thanks for making it.
ALl the best.
Glenn
2thlaserSpectatorColor would be a good idea, however, since laser light is specific to color, that might be why we see either clear sapphire tips, or the brownish color of the disposable tips like the Z’s we have. Good question, we ought to ask. Thanks for the tip on the sealer, and for the kind words on this case. If anyone has any other thoughts on how to do this better, let me know. I know I could’ve used the diode for the soft tissue, just that I get so used to the Er that I don’t opt for the diode that often. I was thinking of that today as I was getting ready to head to the office. Thanks again.

Samuel MossSpectatorHi,
I have been using the Waterlase since last July. I have many questions. I will start with the fact that everyone has had the cold pain when I use the enamel setting. Sometimes, I start with the dentin setting (3.5 W, 65% air, 55% H20). Invariably, they raise their hand that “the cold hurts.” I go to the slow speed with round burs, then go back to the laser. Just about all these sensitive problems are on the molars. I read about defocusing and anesthetizing with the Waterlase. Exactly, how is this done? Do you keep the laser settings the same, pull back, bathe the buccal and lingual for 60-90 seconds? Or do you go to the .25W setting with 0 air and water staying about 10 mm away (I assume this is “defocused”) and bathe the buccal and lingual? Or do you do one or the other but on the occlusal surface? Any word on this would be extremely helpful.Mossman
2thlaserSpectatorHere’s another case I did today, utilizing a “slot”prep technique taught to me by Stu Rosenberg, Kim Kutsch, and Bob Barr. I really feel this is a service to the patient. On the occlual surface there were NO diagnodent readings. On the x-ray, there was mesial decay (don’t have the xray to post, you’ll have to trust me here!). I really tried to keep the marginal ridge intact, and with the pinpoint accuracy of the laser, this is really fast and easy. I started out the normal way, 5.5W, 80%air, 50%water, (BTW, we have found that a 30%differential between water to air ratio seems to work the absolute best for speed of preps), for 90 sec. Then at 5.5W, I enter the enamel to about 1/2 way down the proximal surface, then change to 3W to finish the box, keeping the same air/water settings. Then I cleaned out decay using the small #4 microspoon excavator, and then on 1.25W went back to fine tune the prep prior to placing the composite resin restoration. This is the first interproximal restoration for this patient, low caries rate, and YES, we WILL be replacing that terrible amalgam on #3 in the near future!!!! We used no anesthetic, he felt NOTHING. They usually don’t with slot preps on molars. Here are the pictures…sigh…I need a scope, just don’t have the money for one yet!
This is so fast and easy, less than 20 min in and out. (of course this took about a half an hour as I stopped to take the pictures.) But I thought it was a good example of how to use the laser to preserve tooth structure.
Thanks!
Mark
jetsfanSpectatorMark,
Could you clarify something for me please. As far as the endo… the tooth was anesthetized as usual 5.25 90/90
Once the pulp was visualized, did you reanesthetize the pulp with the z2 at endo settings, or was the tooth asleep enough to get the 15 file to the apex. I tried to do endo on a vital bicuspid without an injection. It was like trying to do endo on a Mexican jumping bean(I hope I am not aging myself). Finally gave intrapulpal and proceeded with the laser.
JETSFAN
dkimmelSpectatorMark, Nice! What did you matrix with. I have found some times that the prep is so small That I can not matrix without opening the slot up larger then the caries.
Where did you find that little spoon?
DAvid
dkimmelSpectatorMark, Did I read your thread correctly? You removed an alloy with the laser. I realized One cusp was gone and the alloy was not vaporized .
Great case. Does your Waterlase have a delay on starting the water at low water %. ? Like 14% and lower.
David
molarmedicSpectatorI have been offered to purchase a 1999 periolase for about 񘠄. Is this machine useful, and secondarily, is the price acceptible?
