Calculus
Two types: supra and sub
Three theories of formation: CO2 theory Ammonia theory Seeding theory

Composition of Calculus
Two thirds of the inorganic component of calculus consists of different types of crystals: Hydroxyapatite – 58% Magnesium whitlockite – 21% Octacalcium phosphate – 12% Brushite – 9%

Dental Factors
Mouth breathing Incompetent lipseal

Dental Factors
Tongue thrusting During swallowing the tongue is thrusted
forward against the teeth instead of being pushed upward towards the palate, leading to increased mobility, spacing and altered occlusion of the anterior teeth.

Iatrogenic Factors
Overhanging or poorly contoured restorations
Subgingival margins of restorations
Prosthodontics – crowns, bridges, dentures
Orthodontic treatment
