The measurement of the setting characteristics of rigid autopolymerizing resins for direct use in the oral cavity.
Differential scanning calorimetry has been used with success to determine working and setting times of autopolymerizing denture and orthodontic base resins. The technique is considered to be far more suitable for this task than thermal methods which are influenced by specimen geometry and heat transfer. Since only a few milligrams of material are required the technique would be suitable for other dental materials whose setting characteristics are of interest.
