The main priority in the treatment of caries complications in permanent teeth with immature roots is to keep the pulp viable to complete apexogenesis . Treatment of pulpitis of a permanent tooth, the roots of which are at the stage of formation, presents objective difficulties for a dentist. The anatomical features of unformed roots, such as thin root walls, a bell in the apical part of the root, which passes into the growth zone, make endodontic manipulations technically difficult. Treatment of permanent teeth with a formed root in children also involves maintaining the vitality of the pulp for the longest possible time. This is achieved by using conservative methods for treating pulpitis. It has been proven that endodontically treated teeth have lower survival rates, in some cases they are latent, and under certain conditions, active foci of infection and intoxication. With the development of clinical dentistry, materials that help preserve the vitality of all or part of the pulp, and methods of their use in teeth with immature roots in children, are constantly being studied and improved.
