Purpose of the study. Based on the study of the clinical and morphological features of pathological resorption, to select an adequate method of treatment that will ensure the performance of certain manipulations according to the proposed algorithm and increase the effectiveness of therapeutic measures. Research methods. Clinical and radiological examination of a patient with cervical intra-root resorption with perforation of the wall of its crown part, histological examination of a biopsy from the area of tooth resorption was performed. A phased treatment was performed using MTA-based cement (Mineral Trioksit Agregat) and subsequent tooth strengthening with a glass fibre post using an electron microscope (Karl Kaps, Germany). Scientific novelty. The idea of the causes of occurrence and clinical manifestations of pathological intraroot resorption of the tooth. The pathomorphological characteristics of inflammatory process in the area of resorptive changes of pulp in the coronal and root parts are presented. The histological picture of the biopsy corresponds to pulp tissues rich in cells with manifestations of an inflammatory reaction, swelling of the intercellular substance, and collagen fibers of the intercellular substance branched into fibrils. The proposed algorithm and the performed stepwise treatment of pathological resorption of the tooth internal part using MTA-based cement and glass fibre post demonstrated a successful result. Long-term clinical and radiological results of treatment confirmed its effectiveness. Conclusions. On the example of a clinical case, the clinical and radiological aspects of intra-root pathological resorption are clarified, the idea of the pathomorphosis of the detected pathology is expanded. The treatment of a tooth diagnosed with cervical intra-root pathological resorption is proposed, which allowed to achieve a successful result, which is confirmed clinically, radiologically and pathomorphologically.
