PURPOSE: We evaluated the effects of gum chewing on the response to psychological @entity1642 induced by a calculation task and investigated the relationship between this response and masticatory performance. METHODS: Nineteen healthy adult volunteers without dental problems undertook the Uchida-Kraepelin (UK) test (30min of reiterating additions of one-digit numbers). Before and immediately after the test, saliva samples were collected from the sublingual area of the @entity1 . Three min after the UK test, the @entity1 were made to chew flavorless gum for 3min, and the final saliva samples were collected 10min after the UK test. The experiment was performed without gum chewing on a different day. Masticatory performance was evaluated using color-changing chewing gum. RESULTS: Salivary @entity3507 levels at immediately and 10min after the UK test were compared with and without gum chewing condition. Two-way repeated measures analysis of variance revealed significant interaction between gum chewing condition and changes in @entity3507 levels during post 10min UK test period. A significant correlation was found between changes in @entity3507 levels and masticatory performance in all @entity1 . CONCLUSION: Our results indicate that gum chewing may relieve @entity1642 responses; however, high masticatory performance is required to achieve this effect.

Masticatory performance alters XXXX relief effect of gum chewing.
