Abstract

OBJECTIVES: To investigate the effect of scaling and root planing (SRP) on the microflora and humoral immune response in adult periodontitis. MATERIALS & METHODS: Clinical measurements, subgingival plaque samples, gingival crevicular fluid and sera were taken from 4 sites in 28 adult periodontitis patients before and after SRP. Polymerase chain reaction was used to determine the presence of A. actinomycetemcomitans, P. gingivalis, B. forsythus, P. intermedia, and T. denticola. ELISA was used to investigate the systemic and local antibody titres to these organisms, and thiocyanate dissociation for the determination of serum antibody avidity. RESULTS: SRP produced a good clinical improvement. ..
