Fig. 5: Oral temperature readings.
From: Determining the performance of a temperature sensor embedded into a mouthguard

Mouthguard temperature sampled every 10 s, sublingual temperature sampled with single-use thermometers every 5 min, buccal temperature sampled with single-use thermometers before and after placing the mouthguard. The exact time points for buccal measurements are shown as red circles.
