Abstract
The purpose of this study was to determine the level of gingival inflammation and the prevalence of periodontopathogenic microorganisms in adolescents with chronic gingivitis, as well as to compare the effectiveness of two approaches in gingivitis treatment-basic therapy alone and basic therapy + adjunctive low-level laser therapy (LLLT). After periodontal evaluation, the content of gingival pockets of 140 adolescents with gingivitis was analyzed by multiplex PCR for the presence of P. gingivalis, A. actinomycetemcomitans, T. forsythensis and P. intermedia. Subsequent to bacteria detection, the examinees were divided into two groups with homogenous clinical and microbiological characteristics. Group A was subjected to basic gingivitis therapy, and group B underwent basic therapy along with adjunctive LLLT. A statistically significant difference between the values of plaque-index (PI) and sulcus bleeding index (SBI) before and after therapy was confirmed in both groups (p < 0.001), though more pronounced in group B. Following therapy, the incidence of periodontopathogenic microorganisms decreased considerably. The best result was obtained in P. gingivalis eradication by combined therapy (p = 0.003). The presence of periodontopathogens in adolescents with gingivitis should be regarded as a sign for dentists to foster more effective oral health programs. LLLT appears to be beneficial as adjuvant to basic therapy.
