Characteristics

Phases	Properties
Alpha (α) form	Brittle at room temperature Gluey, adhesive and highly flowable when heated (lower viscosity) Example: Thermoplasticised gutta-percha used for warm condensation obturation technique
Beta (β) form	Stable and flexible at room temperature Less adhesive and flowable when heated (high viscosity) Example: Commercially available gutta-percha used for cold condensation obturation techniques
Gamma (γ) form	Similar to α- form, unstable
