Abstract
Patients in pedodontics usually do not appropriately report the symptoms of their own disease because of their immaturity. For this reason X-ray inspection plays a big part in diagnosis. It is considered that radiation injury for children is generally more severe than that for adults under the same exposure dose. Therefore it is necessary to detect the effective minimum exposure dose as accurately as possible for protection. The exposure dose was surveyed by use of TLD combined with the 6-films technique for children (child intraoral technique) currently used in the dental clinic. First, the reliability of TLD, the effect of scattered rays and indicator dependence etc. were tested. Second, the distribution of exposure dose in the intraoral technique for children was examined by water phantom. The following results were obtained. 1. It was necessary to select the stabilized TLD as the measuring values were comparatively scattered. 2. Measuring of the effect of scattered rays showed that it was the least in use of Pb, value of which was 101 for air dose 100. This indicated that Pb was the best for scatter protection. 3. For the indicator dependence it was unnecessary to adjust the glancing angle in case it was
