Abstract:
OBJECTIVEIn order to investigate the effect of PABA produced by Streptococcus sanguis on microecological balance of subgingival plaque, different concentrations of PABA were applied to see if it can influence the form and adherence of P. gingivalis.
METHODSAfter adding different concentrations of PABA into 1/2 concentration of BHI media, an anaerobic technique was used to culture P. gingivalis. P. gingivalis grew in the medium was observed by a scanning electron microscope.
RESULTSExcessively high or low PABA concentration could influence the form and adherence of P. gingivalis.
CONCLUSIONPABA produced by Streptococcus sanguis can affect the form and adherence of P. gingivalis. It indicates that Streptococcus sanguis plays regulative effect on the microecological balance of subgingival plaques.
