A dental explorer or sickle probe is an instrument in dentistry commonly used in the dental armamentarium. A sharp point at the end of the explorer is used to enhance tactile sensation. In the past it was usual for dentists to use the explorer to determine the presence of tooth decay on tooth enamel. Some dental professionals have questioned this practice in the first decade of the twenty-first century.〔George Stookey ("USE OF AN EXPLORER CAN LEAD TO MISDIAGNOSIS AND DISRUPT REMINERALIZATION" ), ''The Journal of the American Dental Association'', November 2005, accessed November 17, 2011.〕〔George Stookey ("The Evolution of Caries Detection", 2003 ), ''Dimensions of Dental Hygiene'', accessed November 17, 2011.〕 Since enamel is demineralized in the early stages of tooth decay, the use of an explorer opens a cavity in the enamel where none existed previously. Instead, they argue that fluoride and oral hygiene should be used to remineralize the enamel and prevent it from decaying further. This debate still continues because sometimes decay can be difficult to diagnose without tactile verification. Additionally, radiographs and other products designed to identify decay (such as measuring fluorescence from a laser) help the dental professional make a final diagnosis of tooth decay. There are various types of explorers, though the most common one is the No. 23 explorer, which is also known as a "shepherd's hook". Other types include the 3CH (also known as "cowhorn" or "pigtail") and No. 17 explorers, which are useful for the interproximal areas between teeth. The Tufts 17/23 Explorer, also known as the Wilken's Explorer, contains both No. 17 and No. 23 on the same instrument; opposite sides of each other. ==See also== * Tooth * Sickle * Dentistry * Dental cavities * Oral hygiene * Tooth enamel 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Dental explorer」の詳細全文を読む スポンサード リンク
