An odorless, tasteless powder or crystal that occurs in nature. It is used therapeutically as a phosphate buffer in hemodialysis patients and as a calcium supplement.Anti-Infective Agents, Local: Substances used on humans and other animals that destroy harmful microorganisms or inhibit their activity.

Members contain piperidine alkaloids and GLUCOSINOLATES.Mouth Mucosa: Lining of the ORAL CAVITY, including mucosa on the GUMS; the PALATE; the LIP; the CHEEK; floor of the mouth; and other structures. The mucosa is generally a nonkeratinized stratified squamous EPITHELIUM covering muscle, bone, or glands but can show varying degree of keratinization at specific locations.Fluorides: Inorganic salts of hydrofluoric acid, HF, in which the fluorine atom is in the -1 oxidation state. (McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed) Sodium and stannous salts are commonly used in dentifrices.Diphosphates: Inorganic salts of phosphoric acid that contain two phosphate groups.Saliva, Artificial: A solution used for irrigating the mouth in xerostomia and as a substitute for saliva.Oral Hygiene: The practice of personal hygiene of the mouth.

(From McGraw-Hill Dictionary of Scientific and Technical Terms, 6th ed)Tin Fluorides: Inorganic fluorides of tin. They include both stannic fluoride (tin tetrafluoride) and stannous fluoride (tin difluoride). The latter is used in the prevention of dental caries.Malva: A plant genus of the family MALVACEAE, order Malvales, subclass Dilleniida. The common name of 'Mallow' may sometimes get confused with other plants.Dental Plaque: A film that attaches to teeth, often causing DENTAL CARIES and GINGIVITIS.

(Boucher, Clinical Dental Terminology, 4th ed)Mouth: The oval-shaped oral cavity located at the apex of the digestive tract and consisting of two parts: the vestibule and the oral cavity proper.Chlorine Compounds: Inorganic compounds that contain chlorine as an integral part of the molecule.Gingivitis: Inflammation of gum tissue (GINGIVA) without loss of connective tissue.Saliva: The clear, viscous fluid secreted by the SALIVARY GLANDS and mucous glands of the mouth. It contains MUCINS, water, organic salts, and ptylin.Osteoblastoma: A benign, painful, tumor of bone characterized by the formation of osteoid tissue, primitive bone and calcified tissue. It occurs frequently in the spine of young persons. (From Dorland, 27th ed; Stedman, 25th ed)Sulfur Compounds: Inorganic or organic compounds that contain sulfur as an integral part of the molecule.Drug Combinations: Single preparations containing two or more active agents, for the purpose of their concurrent administration as a fixed dose mixture.Gingival DiseasesSesame Oil: The refined fixed oil obtained from the seed of one or more cultivated varieties of Sesamum indicum. It is used as a solvent and oleaginous vehicle for drugs and has been used internally as a laxative and externally as a skin softener. It is used also in the manufacture of margarine, soap, and cosmetics. (Dorland, 28th ed & Random House Unabridged Dictionary, 2d ed)Denture Cleansers: Substances used to clean dentures; they are usually alkaline peroxides or hypochlorites, may contain enzymes and release oxygen. Use also for sonic action cleaners.Triclosan: A diphenyl ether derivative used in cosmetics and toilet soaps as an antiseptic. It has some bacteriostatic and fungistatic action.Pain Perception: The process by which PAIN is recognized and interpreted by the brain.Chronic Periodontitis: Chronic inflammation and loss of PERIODONTIUM that is associated with the amount of DENTAL PLAQUE or DENTAL CALCULUS present. Chronic periodontitis occurs mostly in adults and was called adult periodontitis, but this disease can appear in young people.Oils, Volatile: Oils which evaporate readily. The volatile oils occur in aromatic plants, to which they give odor and other characteristics. Most volatile oils consist of a mixture of two or more TERPENES or of a mixture of an eleoptene (the more volatile constituent of a volatile oil) with a stearopten (the more solid constituent). The synonym essential oils refers to the essence of a plant, as its perfume or scent, and not to its indispensability.Cariostatic Agents: Substances that inhibit or arrest DENTAL CARIES formation.
