Procedures and data collection
palate
All measurements were performed in the same examination office (ambient temperature 22 ±2 °C). Following inclusion, medical history was gathered, body mass index (BMI) [kg/mAt baseline and following 5, 10, 15, 20 and 30 min of cooling with each of the three cooling sessions, intraoral thermographic images were captured in the following eight intraoral mucosal locations; right buccal, left buccal, upper labial, lower labial, dorsal tongue, ventral tongue, hard palate, and floor of the mouth. Two dental mirrors made of stainless steel were used during the imaging process to access the surfaces of interest.For the cooling sessions using IC, subjects were informed to insert an ounce of ice and move the IC around in the mouth throughout the cooling session, except for when the thermal images were captured. They were also briefed to rinse the melted ice slurry that was obtained before it was swallowed or expectorated. Prior to the cooling sessions with the ICD, all subjects were supervised in how to insert and use the ICD.All procedures were standardized throughout the study and the images were analyzed by a dentist blinded to the cooling procedures.
