Pain is still an actual problem in dentistry, and a usage of anaesthetics can be still limited, so new ways of caries treatment are still being searched in order to ease this process both to a patient and a doctor. Efficiency of chemomechanical tooth treatment to children was studied. 30 children within two age groups of 3-6 and 7-13 years took part in this research, and their teeth with caries were treated in two different ways--chemomechanical and traditional. Teeth with the same class of cavities were treated. There are presented records about the need of anaesthetics' usage, cleaning duration and patients' complaints in this study. Results show that chemomechanical treatment could be as effective as traditional one, causes less pain and lowers the need for anaesthetics. There was noticed less removal of solid tissue cleaning carious cavity.
