Beta-tricalcium phosphate, white mineral trioxide aggregate, white Portland cement, ferric sulfate, and formocresol used as pulpotomy agents in primary pig teeth

Calcium Orthophosphates (CaPo ) and Dentistry

“…In an acidic oral environment, such biocomposites take advantages of the ability of ACPs to release calcium and orthophosphate ions, which potentially can take part in enamel remineralization [ α-TCP and β-TCP: According to the available literature, α-TCP and/or β-TCP (unfortunately, the authors of the publications on the subject not always specify which of them was used) are widely used in dentistry and dentistry-related fields. For example, they are used for augmentation of the surrounding bones [171, [282][283][284][285][286][287][288][289], in maxillofacial surgery [290][291][292][293], as a component of root canal sealers [294], as implant coatings [295], as remineralization [296][297][298][299] and pulpotomy [300] agents, for dental pulp capping [301][302][303][304][305][306], to treat perforations [307,308], as endodontic plugs [309] and to fill various types of bone defects and lesions [310][311][312][313][314][315][316][317][318].…”

The obsolescence of formocresol

“…48 Upon histological examination animal studies have shown superior results for MTA, white Portland cement (WPC), and beta-tricalcium phosphate (b-TCP) over formocresol and FS. 49 Other promising possibilities include enamel matrix derivative (EMD), a material that utilises active odontogenic protein. 50 The majority of research at the present time points to MTA as the most popular choice because of its predictability in preserving pulpal health while promoting healing and regeneration of pulp tissue.…”

Comparative histomorphometric analysis between α-Tcp cement and β-Tcp/Ha granules in the bone repair of rat calvaria

“…Bone substitutes should have characteristics such as biocompatibility, nontoxicity and resistance to deformation. Resistance or not to resorption varies according to the desired application, and if biomaterials are resorbable, they should be metabolized by the body or eliminated by a normal physiological path [3][4][5][6] . Tricalcium phosphate (TCP) and hydroxyapatite (HA) are alloplastic bone substitutes that belong with the class of bioceramics.…”

“…According to Driessens et al 15 , α-TCP plus calcium sulfate hemihydrate provide a pH value between 6.5 and 8.0, which allows for cellular activity. Among other properties, this cement does not swell or disintegrate when exposed to fl uids, does not retract or expand, and does not release heat during the setting reaction 6,27 . Generally, calcium phosphates are resorbed due to osteoclastic activity, forming new bone tissue at the bone-cement interface, thus characterizing the process of osteotransductivity.…”
