The growing prevalence of periodontal and oral mucosa diseases results in increasing number of people in need of orthopedic treatment due to tooth loss, which, accordingly, requires quality dental care.
The aim – is to study the pharmacological action of a new dental drug of combined composition in the form of a mucoadhesive gel under the conditional name "Cholident" for the treatment and prevention of inflammatory diseases of the periodontium, oral mucosa and to facilitate adaptation to removable dentures.
Material and Methods. The study of antiexudative activity of the dental gel was performed on a model of carrageenan edema using electronic plethysmometer, manufactured by WPI. As a reference drug, "Kamistad®" gel (STADA Arzneimittel, AG, Germany) was used. Evaluation of the reparative effect of the gel was performed on the model of thermal burn. At light optical research of histologic micronutrients epithelialization, border zone creation, infiltration of inflammatory cells (macrophages) and angiogenesis have been evaluated.
Results. After application of the gel under study, the antiexudative effect began to appear after 30 minutes, as evidenced by a decrease in the volume of the affected paw, while a similar effect of the comparison drug was observed only 60 minutes after application to the paw. The study drug also showed a longer action, as the antiexudative effect was still observed 120 min after application, while in the control group there was no decrease in paw volume after 90 min of the experiment. Sustained decrease of the combustion wound area in the animals to which the studied gel was applied has been demonstrated. Activation of epithelial proliferation in the border area, increase in the height of regenerating epidermis and formation of a thin layer of cells in the combustion area, signs of demarcation zone formation, and increase in density of newly formed vessels in the border zone dermis have been revealed by the results of histological examination.
Conclusions. The results show that the studied gel has a moderate anti-inflammatory effect, which in severity and duration of action exceeds the comparison drug, reduces the local inflammatory response and promotes skin regeneration in the acute phase of combustion.
