| Research Abstract |
The aim of the present study was to assess the psychological stress of children using salivary amylase activity. The subjects consisted of 13 patients who attended the Pediatric Dental Clinic of Niigata University Medical and Dental Hospital for periodical examinations. They ranged from 8 to 11 years of age (The mean age being 10.7). The subjects who received extraction of teeth, cavity preparation, and application of fluoride were excluded. The first saliva samples were obtained when the child arrived for the dental visits. The second saliva samples were obtained after treatment immediately, and the third saliva samples were obtained 15 minutes after treatment.
Control subjects were 9 dentists who were in good health. The average age of the control subjects was 33.4 yr (ranging 26-42 yr). Saliva samples were also obtained in the same manner. These samples had been kept at -20℃ until the hormone measurements were done.
In the child patients, salivary amylase activity of the third saliva samples was significantly lower (p<0.05) than that of the first saliva samples. However in the control subjects, there were no significant differences between the salivary amylase activities obtained before and after treatment.
The results of the present study indicated that children felt anxiety when they arrived for the dental visits, but children's stress was allayed within 15 minutes after treatments. As a method of measuring stress in children, measurement of salivary amylase activity may be recommended. This is the first report that we assess the psychological stress in children using salivary amylase activity in pediatric dentistry.
