Dynamics of Gingival Indices and Microbiological Findings During Treatment of Plaque-Induced Gingivitis in Children Aged 10-14 Years

Abstract

Background: The study analyzed the dynamics of the clinical periodontal status during the treatment of adolescents with generalized plaque-induced gingivitis. Aim: Assessment of the predominant subgingival microflora in the case of a diagnosed inflammatory process in the gingiva in childhood. Methods: Full-mouth periodontal assessment of plaque accumulation and bleeding on probing with an electronic periodontal probe was performed during the treatment of 34 adolescents with generalized plaque-induced gingivitis. The treatment protocol includes five visits (1, 3, 7, 14, and 30 days). Subgingival biofilm sampling was performed by real-time PCR testing to identify, follow-up in dynamics, and determine the quantities of main subgingival periodontopathogens during treatment. Three samples per child were taken from five teeth with the most severe inflammation. Results: For children aged 10-14 years with generalized plaque-induced gingivitis, two weeks after the start of treatment, the index values for bleeding on probing decreased twice from 53 to 27%. C. gingivalis was isolated before the start of treatment in all children, followed by P. intermedia, P. micros (70,4%) and T. denticola, T. forsythia (52,9%). Representatives of the red complex according to Socransky showing greater resistance to the therapy performed in terms of frequency and amount. Conclusion: The predominant subgingival microflora in adolescents with generalized plaque-induced gingivitis is representative of the orange and red Socransky complex, with index values decreasing smoothly at each subsequent visit during treatment.
