In the first step selected a few cluster, then from each cluster selected some children, randomly. The related from of each student was completed only by probe, mirror, natural light and light. The data were analyzed by X² tests. Findings: From 2500 first permanent molar teeth, 1124 (45.1%) were decayed (300 (45.5%) girls and 325 (44.8%) boys). 46 (1.9%) of teeth were extracted, 27 (1.1%) were filled and 135 (51.9%) were health. 54.8% of decayed first permanent molars are in the mandible that in the left side was more than the right.
