ABSTRACT
<p><b>OBJECTIVE</b>To investigate the polymorphism of FcgammaRIIIb genotype, IgG G2m(23) factor and their associations with the susceptibility to aggressive periodontitis.</p><p><b>METHODS</b>DNA of white blood cells and serum from 21 aggressive periodontitis patients and 26 healthy controls was extracted. Genotype of FcgammaRIIIb and phenotype of G2m(23) factor was determined by allele-specific PCR and dot immunobinding assay respectively.</p><p><b>RESULTS</b>The frequency of FcgammaRIIIb-NA1/NA1 genotype in aggressive periodontitis patients was significantly higher than in healthy controls (P < 0.05). The ratio of subjects with FcgammaRIIIb-NA1/NA1 genotype and positive G2m(23) factor was higher in aggressive periodontitis patients (11/21) than in health controls (5/26) (P < 0.05). However, no statistical difference in distribution of G2m(23) factor alone was observed between patients and controls.</p><p><b>CONCLUSIONS</b>This study indicates that FcgammaRIIIb-NA1/NA1 genotype may be a susceptible genotype to aggressive periodontitis in Chinese population. Subjects with FcgammaRIIIb NA1/NA1 genotype and positive G2m(23) factor may be more susceptible to aggressive periodontitis.</p>
