Results and analysis of microscopic examination of modern methods of preparing baby teeth
Currently, the main reasons for patients ' fear of dental appointments are associated with the use of the most common standard rotational technique for preparing carious cavities. Alternative methods of removal of affected hard tissues are not widespread enough at the reception of dentists, but they have a number of advantages in comparison with the usual turbine tip for a dental unit. The GOAL is to Compare the current methods of preparing baby teeth and find out whether they are effective and acceptable at children's dental appointments. Methods caries of removed baby teeth was prepared using standard rotational and available alternative methods (chemical-mechanical, ultrasound and laser). After the first part of our study, we decided to combine the preparation methods. At the first stage, the samples were initially prepared, followed by comparative staining of the samples with caries detectors. This was necessary to evaluate the quality of removal of carious dentin in all samples. Further, for a more accurate result, a comparative microscopic study of all samples was performed on an electron microscope. This was necessary for a detailed study of the "smeared layer" that is formed as a result of standard rotary dissection and comparison with samples obtained as a result of using alternative and combined methods. Results In the course of the study, it was found that not one of the methods used did not fully meet all the requirements, there were positive and negative aspects everywhere. Conclusion one of the best methods of dissection, in comparison with the rest, were: laser technique and a combination of chemical and ultrasound dissection.
