Bacteremia induced by acrylic and clear removable orthodontic retainers
Hayder J Attar
Ibn Sina National College for Medical Studies, KSA
Introduction
: Wearing orthodontic retainers after comprehensive orthodontic treatment is a regular practice. This makes an
opportunity for the bacteria to enter the blood stream during the procedure. The fact behind the bacteremia is that the wires of
acrylic removable retainer causes trauma to the buccal mucosa, gingival or even the alveolar mucosa and may introduce bacteria
and subsequently bacteremia may occur. Other explanation is that when inserting removable retainer, bacterial deposits on the tooth
surface may be pushed into the gingival sulcus by the pushing effect of the retentive clasps of removable retainer.
Aim of study
: This study is aimed to investigate the incidence of bacteremia in orthodontic patients after inserting clear and acrylic
removable retainers and to compare the colony forming units between both types of retainers.
Materials & methods
: Forty-one subjects with an age range between 8-18 years from both genders were included in this study. Only
34 subjects were suited to this research. Eighteen subjects received acrylic retainer and the other sixteen received clear orthodontic
retainer. For each subject blood sample were taken before and immediately (within one minute) after the insertion of the retainer.
Blood Broth cultures were done on the samples to assess the presence of bacteremia. Post-insertion bacteremia was found in regarding
the acrylic retainer, 12 cases (66.67%) acrylic retainers, whereas only 2 cases (12.5%) was found in clear retainer. There was highly
significant difference (P-value=0.001) in the colony forming unit per ml of blood between both groups, being higher in acrylic one.
Conclusion
: Removable retainer used in orthodontic retention presents a significant cause of bacteremia.
