Denture cleansers
The most satisfactory method to keep the denture clean is by regular cleaning with soft brush, soap and water.
Coarse abrasive cause rapid wear of denture polymer and patient should not use them.
GENERALLY DENTURE CLEANSERS ARE OF FOUR TYPES
1- Powder and paste: They consist mainly of finely divided chalk, zirconium, or pumice and flavoring agents; it is quite abrasive and should not be used vigorously over a period of time.


2- Peroxide cleansers: Powder or tablets, contain sodium perborate mixed with alkaline materials such as trisodium phosphate also detergent and flavoring. A solution is made by water and the denture is immersed in it for a period of time.


3- Dilute hypochlorite solution (chlorine): It should not be used with metals, causing tarnish. If high concentration is used it may bleach the polymers if immersed regularly in it.



4- Dilute hydrochloric acid: This dissolves calcified deposits; it is applied locally to heavily contaminated areas of denture.




• House hold cleansers, bathroom abrasives, and dentifrices with chloroform are contraindicated.
