Adsorption of iron to saliva coated hydroxyapatite. 1983

H Nordbö, and A Attramadal, and H M Eriksen

Saliva coated hydroxyapatite was used as a model to study iron adsorption to pellicle material. The uptake of iron was markedly influenced by its concentration in the medium. Denaturation of the protein film by chlorhexidine, tannic acid, or heating up to 70 degrees C increased the adsorption significantly.

UI	MeSH Term	Description	Entries
D007501	Iron	A metallic element with atomic symbol Fe, atomic number 26, and atomic weight 55.85. It is an essential constituent of HEMOGLOBINS; CYTOCHROMES; and IRON-BINDING PROTEINS. It plays a role in cellular redox reactions and in the transport of OXYGEN.	Iron-56,Iron 56
D002710	Chlorhexidine	A disinfectant and topical anti-infective agent used also as mouthwash to prevent oral plaque.	Chlorhexidine Acetate,Chlorhexidine Hydrochloride,MK-412A,Novalsan,Sebidin A,Tubulicid,Acetate, Chlorhexidine,Hydrochloride, Chlorhexidine,MK 412A,MK412A
D003741	Dental Deposits	Accumulations of microflora that lead to pathological plaque and calculus which cause PERIODONTAL DISEASES. It can be considered a type of BIOFILMS. It is subtly distinguished from the protective DENTAL PELLICLE.	Materia Alba,Dental Deposit,Deposit, Dental,Deposits, Dental
D006358	Hot Temperature	Presence of warmth or heat or a temperature notably higher than an accustomed norm.	Heat,Hot Temperatures,Temperature, Hot,Temperatures, Hot
D006801	Humans	Members of the species Homo sapiens.	Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D006882	Hydroxyapatites	A group of compounds with the general formula M10(PO4)6(OH)2, where M is barium, strontium, or calcium. The compounds are the principal mineral in phosphorite deposits, biological tissue, human bones, and teeth. They are also used as an anticaking agent and polymer catalysts.

D000327	Adsorption	The adhesion of gases, liquids, or dissolved solids onto a surface. It includes adsorptive phenomena of bacteria and viruses onto surfaces as well. ABSORPTION into the substance may follow but not necessarily.	Adsorptions
D012463	Saliva	The clear, viscous fluid secreted by the SALIVARY GLANDS and mucous glands of the mouth. It contains MUCINS, water, organic salts, and ptylin.	Salivas
D044622	Dental Pellicle	A thin protein film on the surface of DENTAL ENAMEL. It is widely believed to result from the selective adsorption of precursor proteins present in SALIVA onto tooth surfaces, and to reduce microbial adherence to the TEETH.
