Abstract: Авторами статьи проведены исследования состояния пульпы резцов, клыков и премоляров нижней челюсти при патологической стираемости горизонтальной формы. Установлено, что состояние пульпы резцов, клыков и премоляров нижней челюсти при их па­ тологической стертости зависит не только от группы зубов, но также от степени патологической стираемости и возраста пациента.; The authors of the article studied the condition of the pulp of mandibular incisors, canines and premolars at their pathological abrasion of horizontal form. We conducted a comprehensive examination of patients with the intact dental arches and with the pathological abrasion of hard tissues of mandibular incisors, canines, premolars of horizontal form of varying severity. In addition to the control group, the patients were divided by age into three experimental groups. The second group consisted of the patients aged 45-54 years. Group 3 was of the patients aged 55-64 years, and the Group 4 included the patients of 65 years and older. The study results showed that in the control group the 31th and 41th teeth reacted to the electric currents 2.68 ± 0.26 and 3.32 ± 1.04 microamps, respectively. The decrease of excitability was investigated in the experimental groups comparing to the control group. In the second experimantal group, the figures of excitability of the 31th and 41th teeth were 12.83 ± 1.66 and 17.94 ± 1.11 microamps, respectively. The third experimental group (55-64 years), consisting of patients with a pathological abrasion of nearly two-thirds of the tooth, is also characterized by a decrease in the excitability of the central incisors, which dissection figures are 21.56 ± 2.46 and 24.75 ± 0.87 mircoamps, respectively. Dissection of teeth increased their electroexcitability on the average from 2 mircoamps to 3 mircoamps. The abrupt decrease of the tooth excitability was investigated in patients of Group 4 (experimental) with completely erased tooth crowns. The figures of tooth excitability were in the range from 64,31 ± 9,84 to 82,5 ± 6,78 mircoamps. It was established that the condition of the pulp of mandibular incisors, canines and premolars at their pathological abrasion depends not only on the group of teeth but also on the pathological abrasion degree and the patient's age.
