Method: Healthy women, 20 regularly menstruating and 20 postmenopausal were selected from patients seen at University of East Sarajevo, Faculty of Medicine. Electrical (electrical pulp tester) and cold (refrigerant spray) stimuli were performed on mandibular incisors, twice in regularly menstruating (menstrual and luteal phases) and once in postmenopausal women. Results were expressed as pain threshold values for electrical pulp stimulation (0-80 units) and as pain intensity scores (visual numeric scale, from 0 to 10) for cold stimulation.
Result: In young women higher pain electrical threshold (not significantly) and pain sensitivity score (significantly) were observed in luteal and menstrual phase, respectively. In postmenopausal women electrical pain threshold was significantly higher while pain intensity score was significantly lower than in young women, regardless of the menstrual phase and painful stimuli.
Conclusion: Higher responsiveness to acute dental pulp pain was related with short-term decreased estrogen level (young women, menstrual phase), while lower responsiveness was obtained in short-term increased estrogen level (young women, luteal phase) and long-term decreased estrogen level (postmenopausal women), regardless of type of stimuli.
