    antecedent irritation can be obtained, and may fre- quently be found in the teeth of quite young people. They are, therefore, not necessarily indicative of previous irritation. (b) A patch of dentine on the wall of the pulp cavity, a calcified prolongation of those dentinal fibrils which have been especially subject to irritation, and which have raised this barrier, or shield, to protect the pulp from further irritation. (c) Intrinsic calcification of the pulp.—The root canal being almost obliterated from the greater part of the pulp being converted into secondary dentine. Destructive.—The pain is usually of a shooting or darting character, and occurring at irregular intervals ; sometimes brought on by heat or cold— especially the latter—or by sweet, salt, or acid substances. The above-mentioned causes may suggest the appro- priate treatment, but the irritation is usually best treated by the use of sedatives^ such as oil of cloves, strong solutions of cocaine, and in children a little carbonate of soda placed in a cavity in the tooth will often afford relief; or escharotics, of which strong car- bolic acid, chloride of zinc, potassa cum calcae, and nitrate of silver may be employed in adults. Nitrate of silver, which is the most efficacious, blackens the dentine with which it comes in contact, and must therefore be avoided near the front of the mouth. If the attacks of pain are frequently repeated they ultimately result in most cases, in acute inflammation and death of the pulp.
