Clinical Trial Summary
The purpose of this study is to evaluate the efficacy of using orthodontic bands with glass
ionomer cement to arrest or reverse interproximal lesions as a preventive treatment compared
to monitoring and oral hygiene.
The investigators hypothesize that placing orthodontic bands with glass ionomer cement will
arrest and possibly remineralize incipient carious lesions compared to teeth that are being
monitored without intervention.
Description:
This study is designed to determine the efficacy of orthodontic bands and glass ionomer
cement in arresting and remineralizing incipient carious lesions as compared to monitoring
for changes.
This is a single blinded, split mouth randomized control trial, with the patient being their
own control. A split mouth study is considered the gold standard because both experimental
and control groups are exposed to the same environmet and conditions within the mouth. This
study design eliminates confounding variables that may occur that could significantly alter
the interpretation of end results (e.g. oral hygiene effectiveness between two patients).
Participants will be screened at their routine periodic dental examination, where they will
receive a dental exam, prophylaxis (cleaning), radiographs and fluoride varnish application
in accordance with the guidelines from the American Academy of Pediatric Dentistry.
Radiographs will be examined by an evaluator to determine if participants meet the inclusion
criteria. Each participant requires at least one pair of permanent posterior teeth with
interproximal caries lesions in enamel or in proximity of the dentinal enamel junction (E1,
E2, early D1). An ideal pair consists of the same tooth type on the left and right side of
the mouth (i.e. tooth #5 and #12, maxillary right permanent first premolar and maxillary left
permanent first premolar). Another acceptable type of pair is same tooth type (i.e. tooth #5
and #21, maxillary right permanent first premolar and mandibular left permanent first
premolar) or two adjacent teeth (i.e tooth #19 and 18 mandibular left first and second
molar). Additionally, patients may also be screened when coming in for other dental treatment
as well.
Each participant will have his or her qualifying lesions randomized equally into two groups,
one that will receive the band, and one that will not. Envelopes will contain the treatment
conditions: Left/Upper/Distal or Right/Lower/Mesial, to indicate that the lesion on either
the left/upper/distal or right/lower/mesial side of the mouth will get banded. They will be
randomly organized and then ordered in the box.
After randomization has occurred, each participant will have a blank orthodontic band
(Denovo) fitted on the treatment lesion and cemented with glass ionomer cement (Fuji).
Additionally, oral hygiene instructions will be reinforced. Participants will be instructed
to return for their routine periodic dental exam in 6 months. Because the intervention is
obvious, blinding the patient or the operator is not possible. At the 6 month visit, the band
will be removed with a band remover prior to their dental exam and cleaning. Routine
radiographs (according to the AAPD's radiographic guidelines) will be taken after the band
has been removed. 20,21,22
A blinded second investigator will examine the pre and post treatment radiographs. Lesions
will be classified initially by ADA CCS, and change will be noted as: progression, arrest, or
regression. A de-identified data sheet containing the data will be sent to a statistician and
a McNemar's Chi-square test will be used to test the differences in the lesion status of both
groups
