Secondary Factors for Periodontal Disease
Ravi Morjaria and Rohan Chopra
Periodontal Disease
What is a Secondary Factor?
Causes disease progression
Divided into local and systemic
Local Factors
Calculus
Dental Factors
Iatrogenic Factors
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%
Calculus
Dental Factors
Root Morphology and anatomical anomalies
Dental Factors
Tooth alignment
Dental Factors
Carious lesions
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
Iatrogenic Factors
Systemic Factors
Smoking and Tobacco Systemic Disease Medications Hormonal Influences Poor Nutrition Stress
Systemic Factors

Systemic Factors
