title: [The clinical evaluation of the quality of tooth filling after exposure to hydroxyethylidene diphosphonic acid].
abstract: Ultrastructure of dental enamel was examined under electron microscope after exposure to hydroxyethylene diphosphonic (HEDP) acid and prophilometry of enamel surface was carried out after its exposure to acid salts; clinical studies in 105 patients aged 18-50 years with different diseases of hard dental tissues were carried out in order to assess the duration of filling preservation after dental enamel treatment with HEDP salts. Clinical results were assessed from subjective sensations of patients and data of examination. The criteria of assessing the results were presence of a filling in a filled carious cavity, marginal adhesion of the filling, alteration of color along the external interface of the filling, caries relapses, status of dental pulp and periapical tissues. Clinical and laboratory studies showed that treatment with HEDP acid creates favorable conditions for tooth filling.
