OBJECTIVE We analyzed the distribution of 10 periodontal bacteria species (Porphyromonas gingivalis, Tannerella forsythensis, Prevotella intermedia, Prevotella nigrescens, Campylobacter rectus, Eikenella corrodens, Actinobacillus actinomycetemcomitans, Capnocytophaga ochracea, Capnocytophaga sputigena, and Treponema denticola) in children, and then compared(More)
OBJECTIVES To examine the occurrence of specific periodontal bacteria in children and adolescents. METHODS Ten putative periodontal bacteria were longitudinally examined in plaque and saliva samples from 119 periodontally healthy children (2-15 years old) using a polymerase chain reaction method. RESULTS Capnocytophaga ochracea, C. sputigena, and(More)
BACKGROUND Porphyromonas gingivalis is considered to be one of the most important pathogens in periodontal disease and its fimA genes have been classified into six variants (types I through V and Ib). A majority of the P. gingivalis organisms isolated from periodontitis patients are type II, followed by type IV, while type I is prevalent in healthy adults.(More)
A 10-year-old Japanese girl with severe tooth mobility in her lower permanent incisors was examined clinically, as well as radiographic and microbiological means. The incisors had severe alveolar bond loss and pocket depths exceeding 7 mm at the first visit, however, 10 periodontal bacteria were not detected in subgingival plaque samples taken from the(More)
