    U7 must be used until the object is attained. If the file is used dexterously, the caries may often be cleared away without removing any of the anterior part of the tooth. The molar teeth, from the great extent of their crowns, are attacked with caries in dif- ferent situations, the more frequent of which are four in number:—in the central depression of the grinding surface; at the neck of the tooth ; at the anterior surface between the cen- tral notch; and between the teeth. Of these the first and last are the more common. When an incipient caries is observed in the central depression of a molar tooth, it is often impos- sible to cut it away with a file, neither can it be properly removed with cutting instruments; since however well they may be tempered, they will be found to make but slow progress when used against enamel:—they are useful only for cutting the bony part of the tootli when the enamel is removed. For eradicating a carious spot thus situated it is requisite to use an instrument of a different description ; and as it is one not to be obtained at the shops, I have considered it requisite to give a diagram of it.
