| Outline of Final Research Achievements |
This study examined the sensitivity of periodontal sensation in upper left first molar in terms of Receiver-Operating Characteristic Curve (ROC curve). ROC curve of periodontal sensation was evaluated by calculating area under curve (AUC) before and after rest (control task), mental arithmetic as psychological stress (mental task) and occlusal loading as physical stress (bite task).
This study showed that AUC of ROC in 10 gf loading was significant smaller than that in 20 gf loading before all tasks, however, after bite task, AUC of ROC in 20gf loading decreased, which caused significant difference not to appear.
