A cold pack (ice gel enveloped by a sealed plastic cover) measuring 2.5 x 5 centimetres was placed intraorally on the vestibular surface of the treated tooth. Each cold pack was kept for ten minutes.3 packs were used for each patient, for a total time of 30 minutes.Patients were instructed to remove the cold pack for 1-2 minutes if they felt extreme cold or a burning sensation .The temperature of the gel was checked by a digital thermometer (Brannan, UK) after it was removed from the freezer and kept in an ice box (Cosmoplast, UAE) containing a cooling gel (Exam Packaging, Belgium).
