Gingival health in children with mixed and permanent dentition with diagnosed pyelonephritis

Sirma Todorova Angelova


Introduction: The share of hospitalizations of children with diagnosed urinary tract infections amounts to 4.6 % to 10 % of all hospitalized children. The interest towards fast and minimally invasive diagnostic tests has been exponentially increasing during the last decade. Saliva has been implemented as a biological medium for multi-aspect diagnostic investigations. The determination of the degree of gingival inflammation based on quantitative verification of salivary white blood cells correlates positively to data obtained by application of conventional parameters for evaluation of the periodontal status. The indicator of salivary blood has been investigated as a significant factor for the assessment of the inflammatory process of gingival tissue.

Aim: The aim of the study is related to exploration, analysis and assessment of gingival health of children with mixed and permanent dentition with diagnosed pyelonephritis in comparison to children without common health disorders.

Materials and Methods: The participants in the study are divided into two main groups - children with pyelonephritis and healthy controls. Each of the 2 groups includes two subgroups based on the type of dentition. A combination of methods has been implemented - clinical, paraclinical, and statistical methods.

Conclusion: Among children suffering from pyelonephritis, the indicator of salivary blood is associated with the degree of gingival inflammation. The significance of the PLI and GI indicators in their role as predictors of destructive inflammatory processes of the gingival tissue is verified. The concentration of salivary leucocytes correlates to the intensity and activity of gingival inflammatory disorders.
