After orthodontic brackets debonding, the remaining resin has to be removed. The
purpose of this study was to determine the most efficient method as well as to introduce
a new method of composite removal. The study was carried out on a sample of 30 premolars,
extracted for orthodontic purposes. Brackets had been bonded using the Ortho
One Bisco composite resin. After the removal of brackets, samples were randomly divided
into three groups of ten. Composite remnants in the first group were removed using
the Band Driver (KaVo). For the second group, the tungsten carbide bur (Komet) was
applied. In the third group, composite remnants were removed manually, using adhesive
removing pliers (ORMCO). The samples were analysed using a light-stereomicroscope
(Olympus). Photomicrographs were examined and the ARI (Adhesive Remnant
Index) was calculated. Post Hoc tests (Scheffe, Tukey) indicated a statistically significant
difference between groups 1 and 2 as well as between groups 1 and 3. The tungsten
carbide bur was found to be the most efficient instrument for composite remnant removal.
