| Outline of Final Research Achievements |
Purpose: The purpose of this study was to use cortisol awakening response (CAR) to investigate the differences in daily life stress experienced by individuals wearing either along-term (LT) or a short-term (ST) dento-maxillary prosthesis following head and neck cancer (HNC) resection. Methods: Salivary samples were collected from 11 LT and 10 ST prosthesis wearers on two consecutive days at two time points, immediately after waking up (T0) and 30 min later (T30), by passive drool collection. Cortisol levels were measured and the differences between the cortisol levels at T0 and T30 (T30-T0) was compared between LT and ST prosthesis wearers. Results: A significant difference was observed in T30-T0 between the two groups. T30-T0 of the ST prosthesis wearers was significantly lower compared with that of the LT prosthesis wearers.
Conclusion: The findings suggest that individuals wearing ST dento-maxillary prostheses following HNC resection experience some sort of daily life stress.
