Ron,

Widened pdl, particularly at the osseous crest, changes in furcation involvement and altered lamina dura are common radiographic findings associated with excessive occlusal loading.

Andy

Ron,

You are exactly right. Look under Nd:YAG section later today for some more pictures to show this……

Bob

Thanks Glenn,

You feeling ocasionally “inadequate” is like Giguere feeling inadequate as a goalie for the “slop” goals Devils got last night! :biggrin:

None of us can be or know all, as me and the rest here simply nod and bow to your clinical, microscopic and photographic skills.

That’s why this forum is so great–we can learn from each other.

As far as wanting to know what’s going on–well–we do.

1. We know from “ancient” histology studies that a “closed system” above a perapical endo lesion will generate new PDL, cementum, and bone.

2. We know from recently finished histology at LSU and Ray Yukna that when we create this same “closed system” as shown here, we also get new PDL, cementum, and bone.

1735 Laser-assisted Periodontal Regeneration in Humans

R.A. YUKNA, G.H. EVANS, S. VASTARDIS, and R.F. CARR, Louisiana State University, New Orlreans, USA

Objective: The Laser Assisted New Attachment Procedure (LANAP) has been advocated for the sulcular debridement of periodontal pockets with the goal of obtaining new attachment. Clinical case reports have reported favorable clinical results, but there is no human histologic proof of regeneration.

Methods: 3 patients with 2 single-rooted teeth with moderate-advanced chronic periodontitis associated with subgingival calculus deposits were enrolled. Occlusal adjustment and direct bond extracoronal splinting was performed. Under local anesthesia, a 1/4 round bur notch was placed at the apical extent of calculus as carefully as possible. One of each pair of teeth received Nd:YAG laser treatment of the inner pocket wall to remove the pocket epithelium (laser settings were 3 watts, 150 pulses/second, 10 hz). Both teeth were then aggressively scaled/root planed with an ultrasonic scaler. The pocket of the test tooth was lased again to coagulate any blood present and to form a pocket seal. Triple antibiotic ointment and a light cured dressing was placed. Control teeth received all of the above except the laser treatment. The patients were seen every 10 days for the first month, then at 2 and 3 months, at which time the treated teeth were removed en bloc for histologic processing. Decalcified step serial sections were stained with H & E.

Results: 2 of the 3 LANAP treated specimens showed new cementum, new bone, and new periodontal ligament in and coronal to the notch. The control teeth had a long junctional epithelium with no evidence of regeneration. There was no evidence of any adverse pulpal or tooth surface changes in either specimen.

Conclusions: This report supports the proof of principle that LANAP can be associated with periodontal regeneration on a diseased root surface in humans.

Have a great day!

Thanks as always for all you contribute!

Hi Bob,

Very interesting process.

How does patient flosses without disturbing the fibrin clot?

Andrew

Hi Bob,

WOW! No flossing and even brushing. What a marketing concept!

This should be highlighted and promoted over the regenerative benefits of your Periolase.

For anyone who is desiring a flossing sabbatical, the Periolase will not only deliver but promise to maintain or even ennhance the preexisting bone level.

For a price, you too can take a flossing vacation.

How’s that for a true testament of the Nd:YAG?

The humor is meant to express my amazement of the healing power of LANAP with your Periolase as you might have noticed.

Andrew

Hi Bob,

Your wife’s cooking? Is that a Freudian slip of your better half’s culinary standard?

Thanks for sharing again.

Great stuff you post, Bob.
