Abstract

Introduction: Despite presence of many self or professional preventive treatments, dental caries has always been a public health challenge. One of them is ICON
Aim: To evaluate the laboratory correlation between ICON resin infiltration (smooth surface) and APF topical fluoride in treating artificial enamel lesion on extracted human premolars and molars.
Materials and Methodology: In the laboratory quantitative research, microscopic assessment was done with ‘Stereo-microscope’ and ‘Digital Imaging Software’ 6.14.4 version on 22 extracted (treated with ICON & APF) human teeth after inducing artificial incipient caries.
Statistical Analysis: t-test was applied to check effectiveness of APF-ICON in MATLAB software, to find mean, median, standard deviation, p-value and confidence level of mean to justify the results appropriately.
Results: A significant inference (p<0.5) was acquired at the end of the study i.e. at 6th week. Statistically, APF showed superiority to ICON with respect to lesion depth (mean 50.2mm).
Conclusion: ICON and APF are one of many ways to provide treatment of incipient caries or white spot lesions and maintain a natural anatomy of tooth structure with a clinical implication that they have potential as an agent.

Introduction

In today’s era, dental caries still poses a prevalent clinical condition worldwide among individuals. Despite presence of many self or professional preventive treatments be it fluoridated toothpastes, mouthwashes, topical applications or pit and fissure sealant, benefiting smooth or proximal surface caries, dental caries has always been a public health challenge.
Various minimally invasive approaches for the treatment of incipient lesions have been proposed in the past with some or other drawbacks. For example, a paste containing casein phospho-peptide amorphous calcium phosphate complexes (CCP-ACP) was used as the re-mineralization paste [1]. The major drawback of using this technique is the high amount of enamel that is eroded as a part of micro-abrasion [1].
And that is when in 2009, infiltration of porous lesion body with low viscosity resin was approached. A new resin product was introduced with an assumption that it might be a promising non-invasive painless technique to restore the healthy form of a tooth structure.
Although, this concept at an early stage was not new. The first attempt to infiltrate porous de-mineralized enamel used resorcinol - formaldehyde-based formulation in the 1970s but, due to its toxic nature, it was substituted for commercially available adhesives. However, due to its variable penetration coefficient, the poor ability of these materials to effectively penetrate natural carious lesions limits their use as agents for caries Infiltration [2].
