摘要
Ten periodontally affected subjects and 10 healthy subjects were selected in order to examine the duration patterns of percussion sounds in all upper teeth, excluding the 8′s. Probing depth, loss of attachment, tooth mobility by ‘Periotest’, bone loss and percussion sound duration via occlusal sound analyser were recorded during the pretreatment period. The following results were obtained from the study: the normal duration of percussion sounds ranged from 4.40–5.33 ms; percussion sound values of periodontal patients were of longer duration than those of healthy subjects; a close correlation between duration and other individual parameters was found in all upper teeth, with the exception of molars.
