Color Stability, Radiopacity, and Chemical Characteristics of White Mineral Trioxide Aggregate Associated with 2 Different Vehicles in Contact with Blood

In vitro assessment of the tooth staining potential of endodontic materials in a bovine tooth model

“…The latter are usually placed in direct contact with vascularized pulp tissue. Uptake of blood components within the material and subsequent oxidation of the heme group present in hemoglobin were shown to be a further and clinically relevant staining mechanism, which is not considered in the present study . Furthermore, if there is saliva penetration at the restoration margins, interaction of the endodontic material with salivary components and bacteria may occur in a clinical situation.…”

“…Color alterations induced by calcium silicate cements have been reported in various studies . Bismuth oxide radiopacifiers have been identified as the main reason for the color change in calcium silicate cements .…”

“…Bismuth oxide radiopacifiers have been identified as the main reason for the color change in calcium silicate cements . Furthermore, uptake of blood components from vascularized tissues may favor further discoloration . Recently, Kang et al.…”

“…Bismuth oxide radiopacifiers have been identified as the main reason for the color change in calcium silicate cements (13,14). Furthermore, uptake of blood components from vascularized tissues may favor further discoloration (9,15). Recently, Kang et al (2015) (16) demonstrated that endodontic cements seem to be color stable when using zirconium oxide as radiopacifiers.…”

Papillary reconstruction and guided tissue regeneration for combined periodontal–endodontic lesions caused by palatogingival groove and additional root: a case report

“…White MTA contains iron and manganese, which have been reported as responsible elements for the discoloration [42]. The minocycline in Periocline, used for bone grafting, binds to tooth calcium ions via chelation to form an insoluble complex, which causes tooth discoloration [43,44]. For discoloration, prophylactic, bonding agent, or flowable composite were recommended to be applied on the coronal access cavity wall to coat dentinal tubules [45].…”
