    Man oh man…….I do get around huh.

    Wish I was in Tampa……not my article.

    I got some really cool cases to post but wonder how much crap I am gonna take for them??

    Albert……I stick by that pretty much.

    Use below 2watts which is 30 Hz and 60 Mj (1.8 watts)
    I fill the chamber with water (flush the bleach out).
    I make sure the tip is at least 2 and better yet 3 mm away from the apex, otherwise you will widen your apex, ask me how I know ( blood suddenly in the canal).

    Fire the laser on the way out of the canal at a rate of 1-2mm per second til you get to the canal orifice. I now keep the water on but the water will often bounce of the stopper. Sometimes I will place a small black mark (jiffy marker ) on the side of the tip , or cut a sleeve from a bur and use that as a stopper which doesnt block the water.

    NaOCL will break down the coating on the old tips……not sure about the newer ones.

    Now Janet, I have also with the microscope noticed a difference in the canals in terms of tissue on the walls with less of it being visible after 20-30 secs with the laser. THat is an honest opinion. At high mag , it oftens looks like Glass and in my heart I think it could replace EDTA for opening the smear layer just before you obturate as well.

    I use it just like Janet does if the bleach hasnt been in there long enough.

    Dont know if I know it all, but guys like Mark are shaping with it………I dont know if I like that, I like NiTi better for that but thats because I want a taper for my warm vertical condensation.

    Hope that helps……..

    PS one thing I have done and you can try this , is that if your case is vital , and the bleach is bubbling alot……

    Remove the bleach and use the laser for 30-45 secs in the canal (best if it is a one canal tooth) , then put the bleach back in and see how much bubbling is occurring……..

    Not as much as before is the usual finding in my hands.

    Hey David, did I read correctly that you had trouble cutting the gingival tissues with the Waterlase? Was the tip damaged, is this a common occurence to have different cutting of the same tissues. Sorry about all the questions but I am a new Waterlase user first cases tomorrow – awesome. Could you also elaborate on your hemostasis control in this technique and you build up and temp crown technique. The temp crown in particular loooked awesome and considering you did it with no assistance even better. Great case thanx for posting.

    Did the endo using Glenn’s technique and it seemed to go really well. Thanks again Glenn, U Da Man! I used local to the RCT/C/Crn, but wonder how it would of went if I tried laser anesthesia. How has everyone’s experience been with using laser anesthesia for endo?

    Andrew, This took about an hour from the time the patient came and went. Seemed like forever. I really do depend on my assistants.
    Cam, The waterlase can cut the gingival tissue well. My tip was fine. It was just odd that the tissue cut differently . That is the healthy tissue on the outer edges cut smoothly were as the granulated tissue seemed to absorb the laser energy and not cut. Be careful at what settings you are using. I am using a higher wattage but defocused then some. Try starting at the lower settings first. I used the diode in this case because I had it and wanted to see how it did with the granualted tissue.
    Hemostasis is a problem with this patient in general. She has parathyroid and some renal problems. Everything was alright ttill I removed bone. Talk about bleed. That is why I packed an epi cord with Al chloride sponge on top. Let it set for 2 min and preped. Not ideal but I was not taking an impression .
    The core was Build-IT with Simplicty as bond. I put the old crown back on and tacked it with composite then took a check bite impression with a bite material ( clear stuff from Miles). Then it was just a matter of sticking the temp. material in the impression and putting it back in the mouth. Trim it up and cement in place. This was the easy part. I was off on the temp color but I was getting lazy by the end of the appt.
    Hope your case went well!

    Glenn posted an open crownlengthing (CL)case recently that got me thinking. The use of lasers has pushed the use of a closed technique for CL. This is a great selling point for the use of lasers. There is nothing like doing a CL , prep and impression all in one app. Beats the heck out of waiting 3 months. I am just afraid that sometimes we get short sighted. Two questions come to mind :
    1.When should you do a closed CL and when is an open CL procedure indicated?
    2. In a closed procedure what are some of things we need to look out for?

    When I eval a case for CL it is not just about that tooth but the adjacent teeth. You have to make sure after CL that you have adequate crown to root ratio and not blowing through a furcation area. The adjacent teeth are just as important. You do not want a negative gingival or osseous architecture. This seems to be one key in doing a closed CL. If you can do the CL and not leave a negative osseous or gingival defect then a closed procedure is indicated.

    I have noticed in the closed CL it is easy to leave a thin layer of bone around the prep. A scaler seems to remove it easily. There is also a tendency to trough the area and the need to go back and blend the bone to get a smooth transition at the interprox as well as buccal lingual. Tougher in the man. molar areas. At times it seems difficult to angle the handpiece along the long access of the tooth. Biolase needs to work on the tips for this. Rather a pain on long preps. So much so would require doing as an opened CL.

    Anyone else have some thoughts on this?

    Hi David,
    Great work!
    It’ll probably take me two hours WITH an assistant.

    Ron, This may sound odd but I have had better luck with the 2.75W /55w/65a defocused with the tissue removal. Far less bleeding to none.
    I agree with the superoxol, nice , clean and works.
    The diode is another great idea. I hear you about not wanting to use anesthic. Just got my TAC gel in today. This stuff is great. Could be a non injection option to allow cord placement or use of the diode.

    Albert:

    Occlusal surfaces of molars can be quite a challenge, and you’ll find that some teeth seem “harder” than others(heredity?,fluoride?).  For me these are also the hardest to prepare without pharmaceutical anesthesia, and usually on the molars I’m going to use some sort of  “caine”.  If the patient is anesthetized, you can crank the setting with the DELight and go through enamel very quickly.  

    For example, today on a 13 yo male I prepared tooth number 18 Occlusal at 355mJoules and 25 Hz with the 80degree tip and yes the patient was anesthetized.  I then prepared number 4 Occlusal and number 31 Buccal Pit at 160-240mJ but ONLY 10 Hz(without any pharmaceutical or “laser” anesthesia).

    My overall NPA(no pharmaceutical anesthesia :biggrin: ) rate today using both erbiums was 66.7% and that made for a very typical and happy day for me!

    Hello: Just a few comments about tip activation with the diode, and especially concerning soft tissue periodontal pocket debridement.
    You always start from the gingival crest and work down to the pocket bottom. Bob Gregg, Del McCarthy and a few of the rest of us old farts were taught by ADL in 1990 to do the reverse, and it made no sense then, and makes much less now. You should first calibrate you fiber extrusion out of the handpiece to the measured pocket depth MINUS 1 mm. Then, remembering to stay on soft tissue (and more precisely on the diseased soft tissue,) move the fiber from the gingival crest down toward the apical portion of the pocket. If you think about it, you can’t easily stay on soft tissue if you start down at the apical extension of the pocket, and you must remember that there’s some depth of penetration of this wavelength beyond the contact area.
    Be very careful with two things: 1) don’t over initiate (not carbonize!) your tip, paying particular attention to avoiding putting carbon on the sides. 2) please clean off as much goop as possible, especially on the sides of the fiber. Otherwise, you can just heat up your endo explorer and accomplish the same thing, which could be some unwanted collateral thermal damage. You already know that diodes only operate either continuously or with very long “pulse” durations, so the thermal relaxation can be minimal.
    Use minimal power settings (I like about 0.3-0.4W. CW) and work quickly.
    Then you can return to the pocket, which is now more of a pool of fresh blood, and perform bacterial reduction with a slightly higher setting (like 0.6-0-0.8W CW) moving faster, like you’re performing hemostasis, again working crown down.
    You can find some articles on this by Nora Raffetto, RDH, who, although she’s one of us veteran laser users, should not be called either old or fart or both. Keep Smiling………..DON

    Hi Don,

    I’ve read many people use pulsed for their decontamination/bacterial reduction and was wondering why you prefer CW?

    Thanks for posting and sharing,

    After reading other people’s posts, they seemed able to achieve higher power settings than I was able. Here’s my max setting at each Hz. Does this seem about right?
    30 hz-195mj
    25 hz-275mj
    20 hz-290mj
    10 hz-290mj
    3 hz-155mj

    The surveys offer interesting snapshots of fluid market conditions so I think they are useful for monitoring the state of the market. However, I think a thought experiment on the positive utilities (fun, standard of care and economics) and the negative utilities (I am doing fine as is, too expensive, too close to retirement etc…) would be more useful at this stage of penetration. There are many factors to consider and many of them are variables that will change with increasing market penetration. I tend to think in simplistic terms and look only at the X-factor. X-factor being the ROI on the lasers. For example, if the gross revenue for an average successful user increases by 15%, what does his/her pre-laser revenue have to be in order for a laser purchase to have positive return? If the TOTAL cost of the laser is &#361600/month, then 12 * &#361600/0.15 = &#36128,000/year. You can add more complexity and real life distributions but the basic idea remains the same.

    Hmmm, I see.

    Let me do some checking tomorrow before I possibly stick my foot in my mouth. I’ll get back with you on this tomorrow evening.
