Assessment of the functional state of the microcirculation system of the dental gingival complex in the dynamics of treatment of patients with low crown height

The height of the tooth crown is one of the key factors for fixing fixed structures. One of the most common reasons for cementation is the insufficient stump area of the teeth, in particular, their small height, respectively, this factor is of great practical importance. Along with this, there are three levels of the gingival complex – low, medium and high, respectively, in such a clinical situation, the dentist will have to make an important choice between the method of preparation, which consists in clinical gum lengthening. To date, there is no differentiated approach to a particular method of therapy, depending on the type of dental gingival complex. The purpose of the work is to analyze the state of the microcirculation system of the dental gingival complex using laser Doppler flowmetry in the dynamics of treatment of patients with low tooth crown height. 416 patients who applied for orthopedic treatment participated in the examination and treatment. Based on the microcirculation parameter, the mean square deviation and the coefficient of variation, an assessment of the state of microcirculatory changes was carried out against the background of therapy before the start of treatment and after 14 days. The results of the study proved that in the near future, patients with gingivectomy and alveloplasty had pronounced microcirculatory disorders, regardless of the gum biotype. The parameters in patients with gum retraction did not change significantly. However, in a short period of follow-up, it is impossible to fully assess the clinical and functional state of the dental gingival complex. It is advisable to carry out further monitoring of this category of patients.
