Objective: The aim of this clinical trial was to assess the effect
of resin infiltration on the progression of proximal caries lesions.
Subjects and Methods: Forty-one patients, aged between
15 and 33 years, with 2 or more non-cavitated proximal
caries lesions were included. In 41 of the adolescent and
young adults, 45 pairs of proximal lesions with radiological
extension into the inner and outer half of the enamel, or into
the outer third of the dentin, were randomly allocated to the
test groups (resin infiltration application + fluoridated toothpaste
and flossing use) or to the control group (fluoridated
toothpaste and flossing use). Standardized geometrically
aligned digital bitewing radiographs were obtained using
individual biting holders. The radiographic progression of
the lesions was assessed after 1 year by digital-subtraction
radiography. The McNemar test was used for statistical analysis.
Results: In the test group 1/45 of the lesions (2.2%) and
in the control group 9/45 of the lesions (20%) showed progression.
The caries progression rate of the control group
was significantly higher than that of the test group (p < 0.05).
Conclusions: Resin infiltration of proximal caries lesions is
effective in reducing progression of the lesion.
