title: Methods for evaluation of working and setting times of periodontal dressings.
abstract: Three different methods were used to determine working and setting times of periodontal dressings. The Gillmore needle and the rheometer employed were not suitable for recording setting reactions. A penetration test was found applicable for determination of working and setting times for all three dressings although they exhibited different setting characteristics.
