Dental explorer: Instrument used for the clinical examination of the patient, which allows the discovery of carious cavities and recurrences of fillings made (to detect leaks at the margins, it must be provided with an extremely sharp tip of approximately 0.2 mm). With this instrument we will be able to detect the quality of the dentin with the presence or not of the “Dental Cry”, characteristic of healthy dentin. ( Friedenthal , 1996 ).

The active part of these instruments can be single or double ended; the latter are the most advisable. They present an acute tip which helps us to discover the sites of carious cavities and to determine the state of softening of dental tissue

The explorer is useful for the correct diagnosis of caries since it can remove plaque or some type of element that can limit correct vision at the bottom of fossae and grooves on the dental surface. It also allows examining the surfaces in which we suspect the presence of caries. There is no need to apply a lot of force to the explorer since, according to studies, this will not give us more certainty about our diagnosis and we can generate injuries to the dental structure. The amount of pressure on the scanner should be equal to that which would be used to scratch a nail , without causing pain or damage. All tooth surfaces must be free ofplate or materials that prevent us from a correct vision. Regarding the initial diagnosis, the fact of the improper use of the explorer can lead us to the destruction of tissues and predispose them to future injuries.
Types of explorers
