Effect of resin infiltration application on early proximal caries lesions in vitro.

Background/purpose: Resin infiltration (RI) material ICON is used in treating early proximal caries lesions, as it depends on a micro-invasive infiltration technology. This in vitro study aimed to evaluate the effect of ICON resin infiltration (RI) on early proximal caries by comparing surface roughness and hardness before and after treatment with RI using atomic force microscopy (AFM), automated microhardness testing system (AMHTS), and scanning electron microscopy (SEM) in vitro.

Materials And Methods: Twenty seven premolars extracted for orthodontic reasons were sectioned buccolingually, creating 54 specimens.

Comparison of Penetration Depth and Microleakage of Resin Infiltrant and Conventional Sealant in Pits and Fissures of Permanent Teeth .

Aim: To assess the penetration and microleakage of a resin infiltrant for the prevention of noncavitated white lesion progression in the fissure system of permanent teeth and compare it to a conventional sealant.

Materials And Methods: Sixty extracted permanent teeth with artificially produced noncavitated white lesions were randomly distributed according to the restorative material into group I (experimental) which received ICON resin infiltration, and group II (control) which received Helioseal F fissure sealant. For the penetration test, restorative materials were mixed with a fluorescent dye (eosin H) before light curing; roots were then amputated, and three buccopalatal microscopic sections were obtained from each tooth.
