Patients often suffer from physical and mental stress in dental implant surgery. The aim of this prospective study is to investigate the relationship between patient character and blood pressure in dental implant surgery.

Fifteen patients were recruited for the present study. All patients had never received implant treatment in the past. To evaluate the patients’ personality trait, NEO-Five Factor Inventory (NEO-FFI) was used. All patients answered 50 questions at the first visit and divided in five dimensions: neuroticism, extraversion, openness, agreeableness, and conscientiousness. The index of physical stress was evaluated by blood pressure and pulse rate.

Ten females and five males (mean 55.5 ± 10.6 years) were evaluated in this study. A significant positive correlation was found between elevation rate of diastolic blood pressure/mean blood pressure and neuroticism score (rs = 0.584, 0.526, p < 0.05). On the other hand, there was no significant correlation between systolic blood pressure elevation and neuroticism score.

In this limited study, there was significant correlation between neuroticism character and diastolic blood pressure or mean blood pressure rising in patients who received implant surgery.
