Aim. Determine the level of marginal penetration of filling materials depending from the resistance of tooth.

Materials and methods.Examined 323 persons among which were found 523 fillings: 480 from composite, 13 — from amalgam, 30 — from cements. Under clinical observation in dynamics were 123 patients. Depending of the using during the treatment of caries of facilities these patients were divided into 8 subgroups: 4 subgroups with low and middle levels of intensity of caries and 4 subgroups with high and very high levels of intensity of caries. In subgroups with low and middle levels of intensity of caries as a pickling agent was used 10% maleic acid, in second subgroup additionally performed postfilling fluoridation; in third and fourth subgroups enamel was pickled with 35% phosphoric acid, in fourth subgroup additionally performed postfilling fluoridation.

Results.Established that at a low level of resistance the choice of pickling agent and application of postfilling fluorination authentically influence at the marginal penetration of the fillings and their clinical condition. A year after the imposition of fillings in patients with low and middle level of resistance their safety is 97,6% and the indicators of marginal penetration while using different pickling agents and postpfillings fluorination not different. In a group of patients with high and very high levels of intensity of caries after a year 91,4% of fillings were retained 8,6% — considered "unacceptable", a significant increase of disturbance of marginal adaptation of fillings are found in the case of 35% phosphoric acid in all periods of observation.

Conclusion. After filling of carious cavities using fluorine compounds helped to reduce marginal penetration of fillings in the early period of observation.
