    摘要: The invention relates to indicator paper which enables a doctor treating a patient to measure the effective wearing time for a removable orthodontic device between two control consultations. Said invention is based on the use of starch in the inventive indicator paper, which is pre-coloured by iodine tincture and is degradable by a saliva enzyme called amylase . The inventive method consists in inserting said indicator paper into the removable orthodontic device and in exposing said paper to the action of a buccal salivary medium, thereby initiating a gradual enzymatic discoloration of the starch and, therefore of the indicator paper according to the device presence in the oral cavity. Said indicator paper consists of several main violet areas which are initially coloured with differently concentrated iodine tincture and arranged in gradient series. The chemical action of the salivary amylase produces a graduated discoloration of the indicator paper by area. The total effective wearing time for the removable device in the patient oral cavity between two control consultations is determined according to the number of the discoloured areas. The inventive device is usable, in particular by a doctor in charge in order to objectively judge the co-operation of the patient in application of the removable orthodontic device (one-maxillary or functional).
