Pregnancy Complication Associated With Periodontal Destruction
CHICAGO - March 2, 2005 - Periodontal inflammation plays a possible role in
the development of preeclampsia, a potentially deadly condition that affects
approximately 5 percent of U. S. pregnancies, according to a study in the
Journal of Periodontology. Study Abstract *
"This finding may pave the way for screening and treating periodontal
disease as a preventive method to reduce the occurrence of preeclampsia,"
said Vincent J Iacono, DMD and AAP president.

General dentists James Shen, DDS and Rily Young, DDS of Huntington,
California and oral pathologist Jerry E. Bouquot, D.D.S. of Houston, Texas
are facing lawsuits alleging that in 1999 and 2000 they acted negligently
and conspired to defraud four patients by diagnosing nonexistent jaw
problems. In each case, the plaintiff sought help for multiple symptoms,
some of which (such as tooth and jaw pain) could have been related to dental
problems and others of which (such as sinusitis and chest pain) that were
outside of the scope of dentistry. In all four cases, Shen and Young
diagnosed "cavitations," removed jaw tissues alleged to contain them, and
sent specimens to Bouquot who confirmed the alleged diagnosis.

Shen and Young are among a small number of dentists who maintain that facial
pain and even pain and diseases located far from the mouth are caused by
cavities (cavitations) within the jaw bones and can be cured by locating and
scraping out the affected tissues. They may also remove all
root-canal-treated teeth as well as other teeth close to the area where they
claim the problem exists. Bouquot coined the term "NICO" in the 1980s.

There is no scientific evidence to support the diagnostic and treatment
methods associated with the NICO concept. The lawsuits allege:

The patients' jaw tissues were healthy and should not have been biopsied or
removed.
Three of the patients each had at least five teeth removed unnecessarily.
All of the plaintiffs have required extensive medical and surgical treatment
to repair jaw damage and disfigurement caused by the NICO surgery.
Shen and Young should have advised medical referral for many of the
plaintiffs' symptoms.

Jaw Cavitations (NICO)

The controversial proposal of a low-grade, non-suppurative, radiographically
"invisible" osteomyelitis presenting as a jawbone cavity associated with
facial pain and trigeminal neuralgia was first described more than 20 years
ago.8 The current version of this concept, so-called neuralgia-inducing
cavitational osteonecrosis (NICO),9 has evolved into an even more
controversial issue that remains unproven and associated with iatrogenic
harm.

Papers supporting "scientific" aspects of NICO have been published in
peer-reviewed mainstream journals. The publications offer changing
explanations with only anecdotal case reports and no definitive etiology,
biochemistry, histopathology, neuropathology or diagnosable clinical
features meeting scientific standards of proof, while advocating repeated
surgical procedures for diagnosis and therapy,10 also without proof of
effectiveness. At present, the existence of NICO as a clinical entity
remains unproven and unaccepted by the majority of science-based
practitioners.11,12 NICO must be evaluated by well-designed studies; until
then, unproven concepts should not be the basis for invasive dental surgical
procedures.

The dubious theory of NICO surgery has been promoted beyond reason by some
practitioners as a cure for arthritis, heart disease, immune disorders and
many pain conditions, again without supporting evidence. The concept of
surgically detecting and removing jawbone "cavitations" has been further
expanded to advocate removal of all root canal-treated teeth and even vital
teeth close to the "cavitation" or "toxic areas."13 A dentist was issued a
Letter of Censure by a provincial regulatory authority for proposing to
extract 6 teeth restored with root canal fillings based on the diagnosis of
pathological jawbone cavities - cavities that a panel of dentists could not
detect clinically or radiographically.14 Tragically, the death of an avid
believer in unconventional medicine (UM) who died of recurrent disseminated
breast cancer was attributed to jawbone "cavitations" by UM supporters.15
NICO is an example of unconventional dentistry (UD) that is less
conservative, more invasive, riskier, less effective and more expensive than
conventional dentistry.

Review of NICO Follow-up Studies

Several follow-up studies are published (Table 1) relative to patients who
have had surgical curettage of bone marrow damaged by ischemia, infarction
or low-grade inflammation. These were almost all informal surveys with the
surgeon asking the patients how they were doing. The investigations by
Roberts et al. were conducted by mailed survey, a step in the right
direction. The 1995 study by Bouquot & Christian (Table 2) was the only one
to not use the patients' surgeons to ask the questions, it was a mailed
survey which was returned to a researcher who was unknown to them. It was
further unique in that it guaranteed anonymity, used a standard pain
assessment instrument (the McGill Pain Survey), incorporated multiple
questions designed to identify patients providing inconsistent data, and had
follow-up as long as 18 years.

Comparison of NICO follow-up studies with those for trigeminal neuralgia
The "gold standard" for facial pain follow-up studies, excluding those
relating to the temporomandibular joint disorders, is the collective body of
clinical studies of patients with trigeminal neuralgia, a pain disorder
which is more precisely defined than most others and one which has been
studied much longer and more extensively than others. This gold standard is
considerably flawed. Of the 85+ trigeminal neuralgia studies published up
to 1998, many had such brief sections on methods & materials that it is now
impossible to say how the study was performed...some had no methods section
at all. Almost all studies were simple searches of the medical records of
affected patients, a technique with obvious biases relative to the patient
telling the doctor what the doctor wants to hear, the doctor hearing only
what he or she wants to hear, etc. These are all honest mistakes but
undoubtedly give a more positive outcome that anonymous surveys which
guarantee anonymity. In fact, only two studies used mailed surveys and
only one used an established pain questionnaire/instrument. The best
studies were those which compared two different treatment modalities, but
these are different types of studies and excluded from the present
discussion. References will eventually be posted here.
