ABSTRACT
<p><b>OBJECTIVE</b>To study the natural progress of different degree chronic periodontitis and its association with IL-1B-511 genetic polymorphisms. METHODS; 100 subjects with chronic periodontitis were selected and examined at baselined and in the 6 month and in 1 year on attatchment loss at 6 sites of each tooth. DNA samples were obtained with buccal swabbing technique and were further analyzed for IL-1B-511 genotype polymorphisms using PCR-RFLP-based method in all subjects.</p><p><b>RESULTS</b>The mean AL increases were 1.43 mm within 1 year. Among 100 subjects, 16 patients with moderate progression (0 mm < AL increase/a year < or = 1.0 mm), 84 patients with rapid progression of periodontal disease (AL increase/ a year > 1.0 mm). There was no significant difference for the distribution and frequency of IL-1B-511 genotype and alleles between the AL increase/ a year > 1.0 mm group and AL increase/a year < or = 1.0 mm group. The progression of periodontal disease (AL increase/a year > 1.0 mm group) was significantly higher in the non-severe chronic periodontitis group than in the severe group (P < 0.05). The percentage of molar was higher as far as the rapid-progress sites (AL increase > 2.0 mm both in the 6th and the 12th months examination) were concerned than that of premolar and anterior (P < 0.05). The number of progressed sites in the severe group was higher than the non-severe chronic periodontitis group (P < 0.05).</p><p><b>CONCLUSION</b>The progress of chronic periodontits varies individually. No specific relationship was found between the progression of chronic periodontitis and IL-1 gene polymorphisms.</p>
