Prolonged Aspirin Chewing Can Damage Teeth, According To Case Study

People who often chew aspirin over a prolonged period could severely damage their teeth, according to a case study in this month's issue of the Journal of the American Dental Association (JADA).  "Aspirin can cause severe damage to both the hard and soft tissues of the mouth," said researchers from the University of Maryland Dental School, Baltimore

Airsonett Airshower Delivers 'Clean Room' Quality Air Directly To The Breathing Zone

The patented Airsonett Airshower they said, delivers "clean room" quality air within three minutes after the unit begins operating with very little, if any, remixing and contamination of the surrounding air. The unit also purifies air in an entire room to levels of an industrial clean room several hours faster than most conventional air purifiers, depending on the square footage of the room, Airsonett noted...
 

long term usage of antibiotics
 
In my mind, there is no doubt about the effectiveness of certain antibiotics
in treating periodontal diseases.  Brian Mealey, DDS, periodontist,
researcher, and speaker on periodontitis and diabetes, says that a course of
doxy when treating a diabetic patient for perio will often help with
bringing the blood glucose level down, as well as benefitting the perio
outcome.

But many of us are uncomfortable with the notion of long term usage of
antibiotics - for any reason.  David, I recommend you read the book "The
Antibiotic Paradox - How the Misuse of Antibiotics Destroys Their Curative
Powers" by Stuart Levy, MD.  It is an eye-opener read!

Also, the April issue of Access magazine contained a compelling article on
antibiotic prophylaxis. Because of all the emerging strains of microbes that
are resistant to ANY antibiotic, there will probably be BIG changes to the
established guidelines.  Here's a quote from Brian Strom, MD, MPH, chair of
biostatistics and epidemiology at U. of Penn.:  "There is no need for
prophylaxis for dental work .   Valve disease is indeed a risk factor - a
strong one.  But one would need antibiotics all year round, as dental work
does not add to the risk.."  Asked how he believes the guidelines should be
altered, he answers succinctly, "They should be eliminated."  He wrote this
because of what he feels is indiscriminate use of antibiotice - all because
of the emergence of new, highly resistant microbes.

Objective The purpose of this prospective, randomized, blinded study was to compare the pain of injection and post-injection pain of the AMSA injection using the computer-assisted Wand Plus® injection system versus a conventional syringe.

Study design Using a crossover design, 40 subjects randomly received 2 blinded AMSA injections using the Wand Plus® system and a conventional syringe, at 2 separate appointments. The AMSA injection site was centered halfway between the midpalatine raphe and gingival margin of the first and second premolars. The pain of needle insertion, anesthetic solution deposition pain, and postinjection pain were recorded on a Heft-Parker VAS for the 2 AMSA injections.

Results For needle insertion, 38% of the subjects had moderate/severe pain with the Wand Plus® and 34% moderate/severe pain with the conventional syringe, with no significant difference between techniques. There was a significant difference for solution deposition pain, with the conventional syringe causing more moderate/severe pain (42% conventional vs. 25% for the Wand Plus®). Regarding postinjection pain, after numbness wore off there was no significant difference between the Wand Plus® injection technique (0% moderate pain) and the conventional syringe technique (8% moderate pain). Postinjection, approximately 8% to 10% of the subjects experienced slight palatal swelling and 2% experienced temporary numbness. These problems resolved quickly and were considered minor.

Conclusions The AMSA injection, using the Wand Plus®, resulted in similar pain ratings for needle insertion as the conventional syringe but statistically lower pain ratings upon anesthetic solution deposition. However, the AMSA, using either the Wand Plus® or a conventional syringe, has the potential to be a painful injection. We found the incidence of postinjection pain and sequelae was low with both techniques.
