Abstract
To determine the cause of fear and worry regarding dental treatment in children, which can be factors for stress during procedures, we measured α -amylase using a simplified chair-side indicator in patient saliva samples obtained before and after treatment in 84 children aged 3−12 years (45 boys, 39 girls). The relationships between measured values and various parameters were examined, with the following results obtained.1.There were differences among individuals as well as wide variations in amylase levels in saliva before and after treatment. However, the value declined after treatment in many cases.2.Although no significant differences related to age were observed in regard to amylase level, that rose after treatment in many patients aged 6 to 12 years old.3.When analyzed by time of day, the percentage of cases with an elevated level after treatment was higher in the afternoon than in the morning, while that of cases with a reduced level was significantly higher in the morning.4.There were scant variations in amylase level when analyzed based on hour or treatment protocol.5.Use of local anesthesia had no significant effect on variations in amylase level.6.Patient characteristics had no significant correlations with amylase levels. However, there were slightly fewer patients with a quiet character who showed an elevated level after treatment as compared to those classified as active or average, while the number of quiet patients with a reduced level was somewhat greater as compared to the other types.Based on our results, we propose that treatment of child patients should be performed with appropriate consideration regarding time of day, use of local anesthesia, age, and personal characteristics. Our findings may also be useful for development of future dental procedures.
