Alginate is also referred to as an irreversible hydrocolloid because once it is mixed a chemical reaction occurs, known as gelation. As the stock metal trays are used impression material thickness of 4 mm is recommended. When the amount of the water-soluble polyether that is a liquid at 25 C. is less than 0.1% by weight, satisfactory effects cannot be obtained, whereas when it exceeds 10% by weight . -, Jennings KJ, Samaranayake LP. 6,17,21,22 Separation of the cast after a short period of contact time will produce a cast with good properties in terms of surface details, dimensional stability, and hardness. Dimensional stability is poor, due to loss of water the impression sets to shrink overtime. Periodontal charting was completed and reveals five areas of probing depths 4mm or greater, #2 distal with a reading of 5mm, #14, distal with a reading of 5mm, #15 distal with a reading of 5mm, and #18 mesial and distal with a reading of 4mm. Different disinfection protocols regarding the type of disinfectant as well as the disinfection method have been suggested for alginate. . Recommendation : it can be concluded that addition of 100-ppm fluoride were effect on the properties of alginate impression materials while addition of 2 % Naf was deteriorated the properties of alginate impression materials.
