The compressive strength of Proto A was comparable with that of Portland cement at all testing periods (<jats:italic>P<\/jats:italic>\u2003&gt;\u20030.05). Additions of bismuth oxide extended the setting time and reduced the compressive strength (<jats:italic>P<\/jats:italic>\u2003&lt;\u20030.05). Both cements and storage solution were alkaline. All cements tested increased by &gt;12% of their original weight after immersion in water for 1\u2003day with no further absorption after 28\u2003days.

Addition of bismuth oxide affected the properties of the novel cement. Further investigation on the effect that bismuth oxide has on the properties of mineral trioxide aggregate is thus warranted.<\/jats:p>","DOI":"10.1111\/j.1365-2591.2007.01330.x","type":"journal-article","created":{"date-parts":[[2007,10,11]],"date-time":"2007-10-11T17:12:39Z","timestamp":1192122759000},"page":"151-157","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":76,"title":["The physical properties of accelerated Portland cement for endodontic use"],"prefix":"10.1111","volume":"41","author":[{"given":"J.","family":"Camilleri","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2007,10,23]]},"reference":[{"key":"e_1_2_7_2_1","volume-title":"Methods of Testing Cement: Determination of Setting Time and Soundness","author":"British Standard Institution","year":"1995"},{"key":"e_1_2_7_3_1","volume-title":"Cement.
