Lingual Braces and Bacteremia after Tooth Brushing
Bacteremia Associated With Toothbrushing and Dental Extraction
Published in Circulation June 2008
Background—Antibiotic prophylaxis recommendations for the prevention of infective endocarditis are based in part on studies of bacteremia from dental procedures, but toothbrushing may pose a greater threat. The purpose of this study was to compare the incidence, duration, nature, and magnitude of endocarditis-related bacteremia from single-tooth extraction and toothbrushing and to determine the impact of amoxicillin prophylaxis on single-tooth extraction.
Methods and Results—In this double-blind, placebo-controlled study, 290 subjects were randomized to (1) toothbrushing, (2) single-tooth extraction with amoxicillin prophylaxis, or (3) single-tooth extraction with identical placebo. Blood was drawn for bacterial culturing and identification at 6 time points before, during, and after these interventions. The focus of our analysis was on bacterial species reported to cause infective endocarditis. We identified 98 bacterial species, 32 of which are reported to cause endocarditis. Cumulative incidence of endocarditis-related bacteria from all 6 blood draws was 23%, 33%, and 60% for the toothbrushing, extraction-amoxicillin, and extraction-placebo groups, respectively (P<0.0001). style="font-weight: bold;">Conclusions—Although amoxicillin has a significant impact on bacteremia resulting from a single-tooth extraction, given the greater frequency for oral hygiene, toothbrushing may be a greater threat for individuals at risk for infective endocarditis.

Choices for Replacing a lost tooth
According to a New York study, a tooth loss ignored for long could lead to an increased risk of loosing adjacent teeth also. The factor that plays a vital role in long term tooth problems after one tooth loss is, the method chosen for tooth replacement. Research shows that a choice of wrong tooth replacement techniques, could hasten the chain reaction of adjacent tooth loss as time passes.
Dr. David Scharf, a Board Certified Periodontist and Dental Implant Surgeon and a Clinical Assistant Professor at New York University College of Dentistry, says “Many times consumers will choose to replace a missing tooth with a removable partial denture because it is the least expensive option. In the long run however, removable partial dentures may be more costly due the loss of adjacent teeth and the need for future replacements. Many people opt to replace teeth with dental implants because they do not compromise the survival of the adjacent teeth.”

Dental Treatment During Pregnancy ?
Pregnant women can safely undergo essential dental treatment and receive topical and local anesthetics at 13 to 21 weeks gestation, says a study published in the June 2008 issue of The Journal of the American Dental Association.
Although obstetricians generally consider dental care safe for pregnant women, supporting clinical trial evidence has been lacking. To address this issue, researchers compared safety outcomes from the Obstetrics and Periodontal Therapy Trial in which pregnant women received scaling and root planing (deep cleaning) and essential dental treatment (defined as treatment of moderate-to-severe or fractured or abscessed teeth).

Era of Digital Impressions ? JADA June 2008
Time to say good buy to Alginates and Silicones ? Digital impressions appear to be practical, and the concept is being perfected, but the need for further research is clear. Digital impressions eliminate some of the negative characteristics of conventional elastomer impressions, but proper soft-tissue management and isolation of tooth preparation margins still is necessary.
The relative cost of digital impressions to conventional elastomer impressions is related directly to the number of impressions made by specific practitioners per month, but a dentist must use a digital impression system for a significant amount of time to compensate for the cost of the device. Nevertheless, the acceptance of the digital impression concept is promising.
