J & J Instruments Explorers: Several components are necessary to provide a fine and functional dental explorer. First, the tips must be sharp so that dental caries and calculus can be precisely located. Next the tips must be both malleable and durable. The correct steel hardened to consistent and exacting standards will ensure the tactile sensitivity that the practitioner demands. Finally, these tips must be joined to a handle that is lightweight and comfortable, yet sturdy. The meticulous marriage of these elements makes the J&J explorer a most effective diagnostic tool.
