Indiana University-Purdue University Indianapolis (IUPUI) / Microabrasion with PREMA Compound (Premier Dental Product Co.,
King of Prussia, Penn.) has been advocated for the removal of superficial enamel
stains. This procedure eliminates stains by removing a microscopic layer of
enamel. The objective of this study was to determine whether the use of PREMA
microabrasion prior to orthodontic bonding affects the tensile bond strength of
an adhesive precoated stainless steel orthodontic bracket. Sixty noncarious
extracted human premolar teeth were randomly divided into three groups of 20
and stored in 3-percent buffered formalin solution. Group I was a control group
that was etched and bonded in the usual manner. Group II received PREMA
Compound microabrasion immediately prior to bonding. Group III received
PREMA microabrasion followed by a six-week storage period prior to bonding.
After bonding, specimens were thermocycled and stored in distilled water at
37 °C for 14 days. The specimens were then loaded to failure in the tensile mode
of an Instron testing machine (Instron Corp., Canton, Mass.). A stress-breaking
apparatus was utilized to minimize all forces other than tensile. The data was
statistically analyzed using one-way analysis of variance at the 0.05 level. No
statistically significant differences were found among the three groups. From
these results it was concluded that microabrasion with PREMA did not affect
bond strength. Enamel microabrasion can be provided prior to orthodontic
treatment without any detriment to bracket bond strength.
