Application of Image J in Quantitative Analysis of the Therapeutic Effect of Resin Infiltration for White Spot Lesions

Abstract

Resin infiltration has been increasing used recently, but evaluation methods of it is not objective or practical in clinical. This article aim to introduce the application with details of Image J in quantitative analysis of the therapeutic effect of resin infiltration for white spot lesions (WSL). Images from 10 maxillary central incisors with WSL were collected by digital camera before and after treatment of resin infiltration. Images were imported into Image J. Two methods (gray scale and ratio of WSL) were performed to acquire data of gray scale and ratio of WSL of each crown before and after treatment of resin infiltration. Date of two methods was statistical analyzed respectively. The Student’s t-test showed significant difference between data from before and after treatment of resin infiltration. Application of Image J in analysis of the therapeutic effect of resin infiltration for WSL is objective and practical in clinical.
