Subject: daily peridex

Does anyone recommend peridex or equivalents to patients for daily 
use.  I recommend (and provide at a discount) Phosflur to my patients 
but wouldn't peridex be a better choice?

here is a comment by the ADA in the November supplement to the JADA 
on using rinses of this type

Dr. Mark Lively,

I just read your post to Charlie. Were you not talking DAMON system up about a year ago? I am glad to hear someone else is having a nightmare using this system. I have about 70 cases and can not wait to finish them. I used the D3s and I can not tell you how many I have rebonded with new brackets and finishing certainly is a challenge . Please share your experiences in more detail.

Subject: first molar extraction

In regard to Mort Speck's beautifully presented case, I have only requested first molar extractions a handful of times, so my experience is limited. In these cases, space closure has varied due to the anatomical location of the maxillary sinus lining. When the first molar is extracted, the lining often recontours occlusally, inhibiting bodily tooth movement during space closure. Since this occurance is not predictable, isn't it somewhat risky?  Anyone have thoughts on subject?

Subject: adult open bite retention

Charlie, I recall a case report by Jack Sheridan (aka Jack the Stripper).  An adult open bite case was retained via upper and lower fixed 3-3 retainers.  On the lingual surface of the canine teeth, Caplin hooks were incorporated into the fixed retainers so that anterior vertical elastics could be worn as needed to maintain the correction.

Please email me directly.  I do not want to be quoted by other reps that are
selling a different system.  This happened to me about 18 months ago.

Hi Jayaram,

Thank you for the reply, and the pictures and reference to your letter, which I have reread.

Unfortunately, all this does not answer my question.  "Where is the scientific evidence supporting a Class I molar relationship?"

Certainly the teeth fit together nicely in Class I - if the overbite and overjet are ideal; if the tip and torque are ideal; if the anatomy of each tooth is ideal; if there is no Bolton's discrepancy; if nothing changes with time; etc., etc.

I was taught (in the 70s) to treat to Class I, and for many years we extracted to achieve this.  Now I ask, why?  I have kept abreast of the orthodontic literature but have seen no valid evidence on this, merely anecdote and opinion.  Given that we practise in an environment of Evidence Based Practice I believe we should alter our paradigms as the evidence leads us.  In 27 years of specialist orthodontic practice, my paradigms have shifted mightily!  That is why I am asking for references to any valid scientific articles.

Try this article, from a colleague of mine:

Subject: Routine radiographs

How often are you taking routine progress radiographs on your 
patients in fixed appliances?
Do you increase the frequency in patients with thin or tapered roots?
Panoramic or upper occlusal?
