Dental sound checker is an instrument for analyzing occlusal sound by visual trace recording. The tracing however is not perfectly stable. For the present study, criteria for evaluation of desirability of occlusion were examined on the basis of frequency of clear-cut sound. It was found that care must be given to the following points. 1. The head must be secured in the up-right position in order to prevent variation in tracing due to deviation in head position when recording occlusal sound. Adoption of the patient's own tapping resulted in stable results. 2. Production of sound is not limited to clear-cut sound even with the subjects with normal occlusion. Therefore, several recordings must be made to determine the tracing characteristic of each subject. 3. Some subjects even with loss of many teeth showed a higher frequency of clear-cut sound tracing when occlusal adjustments were made. Dental sound checker is useful since the occlusal state of the denture can be checked and the desirability of occlusal adjustments can be determined visually at its use. 4. Dental sound checker is useful in ascertaining the state of occlusion and of occlusal adjustment in the subjects with loss of many teeth. However, its use will be more effective when it is accompanied by an over-all diagnosis combining articulatory paper examination and palpation by the dentist.
