Abstract

Objectives: compare the prevalence of four periodontopathic bacteria including Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Fusobacterium nucleatum and Treponema denticola in saliva samples from children with and without Fanconi anemia. Material and methods: Dental plaque samples were collected from 71 children and adolescents, aged 6-18 years old. The samples were divided in three groups: Fanconi anemia before transplant (n=25), Fanconi anemia after transplant (n=23) and control (n=24). The test bacteria were identified using a 16S rRNA-based PCR analysis. Results: A. actinomycetemcomytans was found only in one sample of Fanconi anemia before transplant group. P. gingivalis was identified in one sample of Fanconi anemia before transplant group and Fanconi anemia after transplant group. T. denticola was found in two samples of Fanconi anemia before transplant group. F. nucleatum was observed in all groups. The presence of microorganisms ranged from 30% in the control group to 58% in the Fanconi anemia before transplant group. No statistical differences were found between groups. Conclusion: Systemic alterations found in FA subjects did not affect the prevalence of the four bacteria analyzed.
