Background and Aim: The purpose of this study was to evaluate the diagnostic precision of intra oral digital radiography in detection of dentinal occlusal caries in primery molars.
Materials and Methods: 43 extracted primary molars with no clinical apparent caries were selected at first , then Occlusal surface of 40 tooth with 007 ss white bur cavity was made to a depth of one millimeter from DEJ. At final digital radiography was taken with Dr suni sensor. 83 radiographs observed by 4 observer. Statistical analyzes by SPSS13 and five indices were calculated by a T.Test.
Results : Positive.Predictive.Value and Negative.Predictive.Value to respectively 63/5% and 67/5% was detected, and False. Positive and False .Negative error rates was totally 34/9%, (P<0.7).
Conclusion : In accordance with the diagnostic performance, the digital system cannot be recommended for detection of dentinal occlusal caries in primary molars.
