COMPARATIVE CHARACTERISTICS OF PHYSICO-CHEMICAL PROPERTIES OF DRUGS TOPICAL APPLICATION FOR THE PREVENTION OF COMPLICATIONS OF TOOTH EXTRACTION
Background. A comparative study of the dynamics of iodine desorption from drugs containing iodoform and used after tooth extraction to preserve blood clots and prevention, treatment of inflammatory complications. This took into account the type and form of drugs. The content and desorption of iodine determine the duration of local exposure to the drug on the tissues of the tooth well. Objectives. To study the physico-chemical properties of iodoform containing topical preparations for the prevention and treatment of alveolitis of the jaw. Methods. The objects of the study were complex multicomponent preparations of domestic production, presented in the dental market in the form of gauze bandage, collagen sponge, paste, powder containing iodoform. A standard titrimetric method was used to quantify the iodine content in aqueous systems. For the analysis of changes of iodine content in aqueous model systems applied to the spectrophotometric method in which the concentration of a substance was assessed according to the calibration chart from 0 minutes to 48 hours. In the model solution, the albumin and pH were changed, iodine concentration was determined in 1, 15 and 30 min. Results. Medications significantly differed in both the number of iodoform and desorption in the aquatic environment of the iodine. However, the content of iodoform in the preparations did not exceed the maximum permissible concentration. Desorption of iodine from the bandage after 15 minutes is significantly less than from the viscose flagellum. Desorption of iodine from the collagen sponge remains constant for 24 hours., but increases after 48 hours. Desorption of iodine from the powder is reduced after 45 minutes. Desorption of iodine from the paste gradually increases, reaches a maximum of 105 minutes and persists after 48 hours. In the albumin-bound state, iodine is more easily desorbed in an acidic medium, and at low concentrations of iodine, desorption in a neutral medium is significantly less. Conclusions. The duration of action of iodoform when applied topically affect the dosage form of the carrier (fiber, sponge, paste, powder), the concentration of the drug, the pH and albumin content in the aqueous medium.
