Bacteremic capacity of a minimally invasive flapless accelerated orthodontic technique
Volume 6, Issue 3, September 2017, Pages 105–108
Abstract
Objective
The
aim of present prospective cohort study was to investigate prevalence
of bacteremia after a minimally invasive flapless accelerated
orthodontic technique.
Material and Methods
The
sample consisted of 30 orthodontic patients (18 female, 12 male; mean
age: 19.57 ± 0.5 years). All patients had Class I malocclusion and had
fixed orthodontic appliance treatment. The flapless technique was
performed with a reinforced scalpel on the labial aspect of the
mandibular incisors to separate the interproximal cortices
transmucosally. Using aseptic technique, two blood samples of 20 mL were
collected before and 30 to 60 seconds after the flapless technique. The
blood was aseptically inoculated into culture bottles and incubated at
35°C for 2 weeks. Medium alterations showing bacterial growth were
investigated by using Gram staining. The bacteria were identified by
VITEK 2 (bioMérieux, Marcy l'Etoile, France) automated microbiology
identification system. The result was analyzed statistically using the
McNemar test, with P < 0.05 indicating statistical
significance. The intensity of bacteremia was expressed as
colony-forming units per milliliter.
Results
No significant difference between the preoperative and postoperative samples were determined with respect to bacteremia (P = 0.335). Only Streptococcus oralis was detected in two postoperative samples.
Conclusion
A minimally invasive flapless accelerated orthodontic technique is not related to transitory bacteremia, as Streptococcus oralis was detected in only two postoperative samples.
