THREE UNUSUAL CASES OF PAPILLON-LEFEVRE syndrome with late onset of fe
atures and relatively mild periodontal disease are presented. These ex
amples confirm some of the late onset of features and mild periodontal

olymorphonuclear leukocyte chemotactic, phagocytic, and bactericidal a
ctivity, and therapeutics with regard to this syndrome are discussed.
