Endodontic Sealers & Cements a large range of endodontic sealers are available commercially. According to their chemical composition they are classified into various groupings.

The results showed that there was a significant difference (p<0.05). Between the compressive strengths of zinc phosphate cement in group III (2 months before the expiry date). Group I (2 years and 5 months before the expiry date), and group II (11 months before the expiry date). It can be concluded that there is a significant decrease n the compressive strength of zinc phosphate cement near its expiry date.
