For the different forms of stomatitis, and especial mercurial stomatitis, the tincture of iodine is used in the form of a gargle; for an injection in alveolar abscess it is diluted or combined with carbolic acid, glycerin and other agents; for fungous growths it may be used alone, or combined with rectified alcohol; for ulcerations of gum and mucous membrane it is generally combined with carbolic acid; for periodontitis it is combined with the tincture of aconite root, and is regarded as being almost a specific for the incipient stages of this affection, as it relieves the inflammation by retarding the circulation and stimulating lymphatic action. Either the officinal or compound tincture is employed with an equal quantity of the tincture of aconite, the preparation being applied to the gum over root of affected tooth, which should be previously dried of moisture, by means of a camel's-hair brush or cotton on the point of an excavator. The mouth should be kept open and the part protected until a metallic pellicle is formed. Iodine is also a valuable disinfectant and germicide in the treatment of alveolar abscess (in the form of the compound tincture), used as injection throughout the pus tract, and for root canals and the pus-pockets of alveolar pyorrhoea.

A valuable combination of iodine, carbolic acid, glycerin and water is known as u Boulton's Preparation," and is a useful application in the form of injections, gargles and lotions. For the chronic form of alveolar abscess, and also for the acute form, after more powerful agents have been employed, it is a useful remedy, possessing antiseptic and stimulant properties in a marked degree; it also possesses the property of modifying mucous membrane and diminishing sensibility; hence it is useful in ulcerations, etc. Tincture of iodine combined with creasote or carbolic acid is a powerful application in periodontitis, suppuration of necrosed teeth, ulceration of margins of the gums and for fungous growth, as it stimulates debilitated parts and destroys such as are too weak to be restored. A colorless tincture of iodine is composed of glycerin and aqua ammonia in combination with the iodine, but the presence of the ammonia restricts its use. Another colorless tincture, in which sulphate of soda is substituted for the ammonia, is less irritating in its effects.

The addition of water and honey to the officinal tincture of iodine will render it suitable for a gargle for inflamed and ulcerated parts. The iodide of potassium is employed internally in mercurial stomatitis, dental exostosis, facial neuralgia, convulsions of dentition, periodontitis, looseness of the teeth, tumefaction and sponginess of the gums, syphilitic and scrofulous ulcerations of the mouth, caries and necrosis of the maxillary bones.

Tincture of iodine mixed with glycerin is claimed by Dr. Hammond to be more effective as a local application than the plain tincture. This is due to the retardation of the dissipation of the iodine, or more probably to the skin remaining soft, and therefore in a better condition for absorbing the drug.

Iodine Trichloride is formed by passing chlorine gas over iodine. It is obtained in the form of reddish crystals, is soluble in its own weight of water, and almost as readily in alcohol, and either solution can be mixed with glycerol without decomposition. Dr. Belfield regards it as a powerful local antiseptic for irrigating suppurating wounds, and tuberculous processes. He uses solutions of 5 to 20 per cent, in equal parts of water, alcohol and glycerol.
