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.
