Introduction. Dental pulp the richly vascularized and innervated connective tissue. The pulp sensibility for stimulation depends on free nervous terminations and the only pulp response to different irritants is pain. Patient’s age can substantially determine pulp response for different stimuli. Aim. The aim of the study was to determine a pulp threshold sensibility using electric pulp test in patients over 55 years old. Material and methods. The study group was composed of 226 patients, 110 male and 116 female in age 55 to 110.The average age was 69,4. Total number of teeth was 1619, of which 153 were roots, which were classified for extraction. Electro sensibility of 1342 teeth was assessed using electric pulp tester- Vitality Scanner 2006 (Sybron Endo). The pulp sensibility ranges were evaluated separately for upper and lower teeth and different classes of teeth: incisors, canines, premolars and molars. Achieved data with values of minimum, maximum, median, mean and SD were presented in tables. Results. Ranges of pulp sensibility were different in individual classes of teeth. The lowest mean values of pulp response sensibility were obtained for mandibular lateral incisors and for canines the values ranged from 33,7 to 35,6. Among premolars the lowest value was obtained for second maxillary premolars (30,4) and the highest for first maxillary premolars (35,4). The lowest average pulp sensibility threshold was obtained for first maxillary molars (32,9) and the highest for third mandibular molars (46,8).

Key words: electric pulp test method, dental pulp vitality, elderly patients.
