Stainless steel crowns are invaluable restorative material for the treatment of badly broken down primary teeth in pediatric dentistry. But it is difficult to fit margin because selection of size is not easy and they are not adjusted for Korean children. The purpose of this study was to examine and analyze the marginal adaptation of stainless steel crown of posterior primary tooth. Marginal surface was taken by Fine Pix S602 digital camera and measurements of crown were recorded at 20 points that were randomly selected for marginal gap evaluation by Kappa image base program.

1. Mean marginal gap were large upper 2nd primary molar, lower 1st primary molar, lower 2nd primary molar, upper 1st primary molar in order(p<0.05).

2. Mean marginal surface dimension ratio was more than 20£¥ irrespective of tooth.

3. Largest amount of marginal gap was shown at mesial surface in upper 1st, 2nd primary molar and distolingual surface in lower 1st primary molar, buccal surface in lower 2nd primary molar.
