Sub-gingival calculus present with signs of inflammation
Progression rate: slow-moderate
No marked familial aggregation
Localized (< 30% sites) or Generalized (30%/ more sites)
Severity graded: slight (mild), moderate / severe
Circum-pubertal / under 30 yr
Severity of destruction ≠ irritant
Sub-gingival calculus minimal/ absent with little or no signs of inflammation
Rapid rate of progression
Marked familial aggregation
Localized (1st molars and incisors) or Generalized (at least 3 permanent teeth other than 1st molar and incisors
