Subjects were randomised into two groups and received either scaling and root planing quadrant by quadrant at 2\u2010weekly intervals (Q\u2010SRP group) or same\u2010day full\u2010mouth scaling and root planing (FM\u2010SRP group). Clinical measurements and serum samples were obtained at baseline and approximately 6 weeks after the last clinical intervention (R1) and 6 months after the initiation of therapy (R2). Furthermore, serum samples were obtained from each patient undergoing therapy (Q\u2010SRP and FM\u2010SRP) at 3 bi\u2010weekly instances so as to determine the short\u2010term effects of each session of scaling and root planing on the dynamics of the humoral immune response. Serum antibody titre was assayed by enzyme\u2010linked immunosorbent assay (ELISA) and antibody avidity was measured by thiocyanate dissociation against five putative periodontal pathogens: <jats:italic>Porphyromonas gingivalis<\/jats:italic>; <jats:italic>Actinobacillus actinomycetemcomitans<\/jats:italic>; <jats:italic>Prevotella intermedia<\/jats:italic>; <jats:italic>Treponema denticola<\/jats:italic> and <jats:italic>Bacteroides forsythus<\/jats:italic>.<\/jats:p><jats:p><jats:bold>Results: <\/jats:bold> Both therapies resulted in similar antibody titre reductions against the majority of the organisms tested and although there was a distinct trend for antibody avidity to increase following therapy, this was not found to be statistically significant, reflecting marked inter\u2010individual variation. In addition, no evidence emerged from this study to support increased antibody titres following the active phases of both treatment approaches due to an inoculation effect. Nevertheless, significant short\u2010term increases in antibody avidity to most test bacteria were noted for both treatment strategies.<\/jats:p><jats:p><jats:bold>Conclusion: <\/jats:bold> Both therapies were associated with a reduction in antibody titres and an increase in the binding ability or avidity of antibodies, but there was a marked inter\u2010subject variability and statistical significance was reached for only some of the test bacteria. No significant differences in the humoral antibody dynamics were found between the two treatment approaches.<\/jats:p>","DOI":"10.1111\/j.0303-6979.2004.00463.x","type":"journal-article","created":{"date-parts":[[2004,2,10]],"date-time":"2004-02-10T10:32:37Z","timestamp":1076409157000},"page":"152-159","source":"Crossref","is-referenced-by-count":32,"title":["Quadrant root planing versus same\u2010day full\u2010mouth root planing"],"prefix":"10.1111","volume":"31","author":[{"given":"D.
