On 1 March at 14:30 in an open meeting of the Medical Promotion Council of RSU to be held in the Hippocrates Lecture Theatre (Riga, 16 Dzirciema Street) Jūlija Kalniņa will defend her doctoral thesis “Ozone therapy in prevention and treatment of carries in permanent teeth”.

Dental caries is a major oral health problem, affecting 60–90 % of school children. Contemporary dental caries treatment and prevention methods allow to detect caries at an early stage what accounts for a considerable reduction in the intensity of teeth decay. Ozone therapy is a novelty in dentistry and is applied both for prevention and also for treatment of dental caries. Ozone destroys cariogenic bacteria – one of the main causes of dental decay. It is a painless and fast treatment solution, what is a vital aspect of the therapy, knowing that many children have certain fears associated with visiting a dentist.

The main scope of the research was to determine the efficiency of ozone therapy in children, by analysing changes in the mineralization of dental tissues during caries prevention and treatment in permanent teeth.

Changes in dental tissues following application of ozone and various conventional means of prevention (fluoride varnish and sealants) were observed for the period of time of two years.

The thesis covers three parts – the first is devoted to determining and assessing dental carries incidence rate in the target group, oral hygiene and the condition of periodontium, likewise oral care and eating habits. The second part determines the impact of ozone on dental tissue mineralization in caries prevention in premolar teeth, whereas the third part deals with ozone impact on dental tissue mineralization for early stage caries treatment in permanent molars.

The research has proven that ozone therapy may be applied in dental caries prevention and treatment in permanent premolars and molars. Introduction of ozone therapy would improve dental decay prevention and treatment quality; reduce the time of treatment and wold be a vital acquisition for patients and dentists.
