  1. Marital status and number of teeth: * = Significance (p < 0.05) between the marital status groups.
  2. Social group and number of teeth:
  3. a = significance (p < 0.05) between all social groups.
  4. b = significance (p < 0.05) between high and low social groups.
  5. c = significance (p < 0.05) between medium and low social groups.
  6. Educational level and number of teeth:
  7. a = significance (p < 0.05) between all education groups.
  8. b = significance (p < 0.05) between low and medium education groups.
  9. c = significance (p < 0.05) between low and high education groups.
  10. The analyses of variance method was applied including a post-hoc analysis (LSD).
