PATIENT SELECTION FOR THE LASER TREATMENT BY ESTIMATION OF THE THERAPEUTIC FAILURE PROBABILITY OF SURGICAL TREATMENT

Abstract

The study is dedicated to the study of inflammatory and destructive periodontal diseases. Predicting the probability of a favorable outcome or treatment failure is one of the most important doctor’s tasks when choosing a particular method. This problem could not be solved without using a large amount of data characterizing the patient's condition at a particular point in time. The empirical approach to this problem depends largely on individual experience and does not imply obtaining any formalized (numerical) probability estimates of successful or, on the contrary, unsuccessful end of treatment. Correct and effective using of dental lasers in clinical practice requires knowledge of their effects on tissues of the oral cavity. Each type of laser has its properties that are used to solve clinical cases. Laser radiation requires an approach that is significantly different from the traditional use of dental instruments. To determine lasers therapeutic indications for the treatment of inflammatory and destructive periodontal diseases, we applied biometric approaches to the development of mathematical models using multidimensional analysis, allowing to obtain qualitative assessments for optimization of method and treatment strategy selection. The development of predictive models was carried out in several stages. Each of the generally accepted dental signs characterizing periodontal disease could not be a reliable criterion for the effectiveness or ineffectiveness of surgical treatment. Comprehensive assessment using a logistic (exponential) model of the probability of a particular treatment outcome with a high degree statistical reliability makes it possible to select patients for whom treatment with laser technologies is recommended.
