Abstract Introduction: A change in natural and shining properties of Enamel is called as developmental defect of Enamel. Enamel defects caused a negative change in aesthetics of teeth and increased the susceptibility of caries, Therefore, some opaque spaekles will appear on the teeth which destroy tooth aesthetics. Causes of enamel defects are divided into two major groups such as local and systemic. Objective: The objective of this study consist of: Developmental defects of enamel (DDE) incidence in permanent dentition of children between 11 to 13 years old in Rasht (2002-2003). Materials and Methods: In this cross-Sectional descriptive study, 578 students (286 boys and 292 girls) based on multistage cluster sampling and DDE index were studied, the researcher employed DMFT index to study condition of caries in the given subjects and x2 test was used. Results: Results indicate that 1-There is a 59.8% developmental defects of enamel incidence among children between 11 to 13 years old in Rasht and most of incidence occurs in Labial tooth surface. 2- The mean of DMFT is 2.01 in an SD of 2.05 (2.01 ±2.05) 3- According to X2 test, there isn’t any significant difference of enamel defects among ages and sexes. Conclusion: result s of this research showed that half of this student had developmental defect of enamel and anterior teeth had more defects that is related to longer developmental time.
