Abstract
The purpose of this study was to investigate the frequency of the anginosus group streptococci isolated from apical periodontitis of deciduous teeth.
The pus samples from root canals (3 cases) or from gingival abscesses (4 cases) of deciduous teeth in 7 children who were from 3 years and 1 month old to 9 years 6 months old, were gathered and anginosus group streptococci were isolated using Streptogram®(Wako)a nd 16 S rRNA sequencing.
In 7 cases, S. anginosus was isolated from 3 cases, S. intermedius was isolated from 2 cases, and S. constellatus was isolated from 1 case. Among the samples in 1 case, S. anginosus and S. intermedius were isolated. The anginosus group streptococci were isolated from 5 cases in 7 cases,71.4%.
This is the first report showing isolation of anginosus group streptococci from the apical periodontitis of deciduous teeth using the method mentioned above.
