Research Abstract

In annual dental health examinations at school, gingival condition is divided into healthy, observation of gingivitis (GO) and gingivitis (G). However, the level of gingival health status can take on any value from healthy to severe gingivitis. School dentists need to minimize the impact of different examiner styles in school settings involving more than one examiner. The aim of this study was to develop a computer training soft to improve their ability to evaluate gingival health status using color photos of the anterior teeth. A probability index was calculated from percentages for each report level of 39 training dentists: judgment which was equal to the golden standard was given more weight than the other two. This software can be used under two conditions : a test or calibration tool toward researchers group at the same time using LCD projector, or individuals sit in front of the computer and run the program, to improve their diagnosis ability. It takes 5 minutes per trial. Levels 5-10 will be used to keep examinees motivated or to give them a sense of progression.
