the levels of endotoxin found on the root surfaces of these individual , periodontally involved teeth at varying times following in vivo root planing support the following conclusions : the concentration of endotoxin present on diseased root surfaces is markedly reduced , but not eliminated , by in vivo root planing , significant retoxification of root planed surfaces occurs within a relatively short time period after root planing and biological responses to such toxification conceivably may lead to subsequent phases having reduced levels of endotoxin .
