Being method in order to wash the buccal cavity, the said method, being the tooth inside process and the buccal cavity which position the ideal device in order it detects and to remove the plaque and from the surface of the buccal cavity inside the buccal cavity, it applied the fluorescent to the tooth, the surface of the tooth inside the buccal cavity, the said surface of the tooth the fluorescent when being made to contact, although firefly luminescence is offered, with incident radiation of effective wave length, the process which collects at least the one part of firefly luminescence the process which you wash and irradiate and, over 1st period and, 1st average firefly luminescence value (APV1The process which collects at least the one part of firefly luminescence) the process which is decided and, over 2nd period and, 2nd average plaque value (APV2) the process which is decided and the process which compares APV1 with APV2 and, it includes, method.口腔を洗浄するための方法であって、該方法が、口腔内の口腔の表面からプラークを検出及び除去するために好適なデバイスを位置決めする工程と、口腔内の歯であって、蛍光剤を歯に適用した、口腔内の歯の表面を、歯の該表面を蛍光剤と接触させられたときに蛍光発光を提供するのに有効な波長の入射放射線で、洗浄及び照射する工程と、第1の期間にわたって蛍光発光の少なくとも一部分を収集する工程と、第1の平均蛍光発光値(APV1)を決定する工程と、第2の期間にわたって蛍光発光の少なくとも一部分を収集する工程と、第2の平均プラーク値(APV2)を決定する工程と、APV1をAPV2と比較する工程と、を含む、方法。
