< Topic >Being simple structure, it possesses size and the weight which are equal to the probe which has the former probe furthermore, without accompanying the enlargement of the u you can inspect the u , furthermore, the early u and, hole diameter is small, but it designates that the probe for u diagnosis which easily can discover the u which is being advanced is offered as purpose. SolutionsThe grip section it is provided in the drawer back of 3 which the user grips and grip section and 3 in order for the intermediate section to project on advanced side of 5 which was formed to crookedness form and the said intermediate section 5, it is locked, fixed place focusing on elasticity it becomes deformed and probe section 9 of the acerose condition which is crooked and, it has, presses the point of probe section 9 on flank and in order to diagnose the u the occasion where it moved with the crimp and catching of the said probe section, it features that it is constituted. < Selective figure >Figure 1【課題】簡単な構造であって、従来の探針を備えたプローブと同等の大きさおよび重さを有し、さらに、う蝕の拡大を伴わずにう蝕の検査ができ、さらに、初期のう蝕や、穴径は小さいが進行しているう蝕の発見を容易に行うことができるう蝕診断用プローブを提供することを目的とする。【解決手段】使用者が把持する把持部3と、把持部3の先側に設けられ屈曲形状に形成された中間部5と、該中間部5の先端側に突出するように固定され、固定箇所を中心に弾性変形して屈曲する針形状の探針部9と、を備え、探針部9の先端を歯面上に押し当てて移動した際に該探針部の折れ曲がりと引っ掛かりによって、う蝕を診断するように構成されたことを特徴とする。【選択図】図1
