Короткий опис (реферат):
The prevalence of caries in the world is still very high. Surgical treatment is used most often. The essence of the method is to remove the affected tissues and replace the defect with filling material. The stage of preparation is the most labor-intensive for the doctor and requires considerable effort, experience and modern equipment and tools. Depending on the depth, location of the cavity, age of the patient, the state of oral hygiene and group affiliation of the teeth may be different features of the preparation. To date, there are a number of methods of preparation of hard tissues of the teeth. But the most popular are still rotating tools and the use of turbine and a variety of micromotor tips. However, the preparation of enamel and dentin using boron has a number of disadvantages: vibration, unpleasant sound, overheating of the hard tissues of the tooth, soreness. Therefore, one of the current problems of modern dentistry is the search for and study of alternative methods of preparation.
