“…13 This has resulted in a signifi cant body of research showing that PC appears to be a useful substitute for MTA. 17,21,24,27,31,32 However, only four studies reported the use of PC in conservative pulp therapy with considerable success in rats 24 and dogs. 16,17,23 To the best of our knowledge, this is the fi rst randomised controlled clinical trial assessing the effectiveness of PC in human primary teeth and comparing this regenerative dressing agent with MTA.…”

“…In addition, both MTA and PC allowed for dentin bridge formation after pulpotomy performed on dogs. 16 Min et al 27 observed that PC allowed the expression of mRNAs of a dentin-specifi c protein and a noncollagenous protein involved in mineralisation in cultured human pulp cells. De-Deus et al 28 presented a case in which substantial periapical healing occurred with the use of PC to create an apical plug in the root of an immature tooth in human.…”

“…The study also demonstrated that besides lowering the resistance to compression, the addition of bismuth oxide adversely affects the physical properties of MTA, contraindicating its use as a sealant in root perforations, especially in cases where high-resistance materials are recommend, such as furcation perforations. Studies comparing the biological properties of MTA and Portland cements have used Portland cements without additives 13,16 . Additives may improve the mechanical resistance of the cement, but also damage periradicular tissues.…”

“…Ordinary (type I) and white Portland cements have been compared with MTA in recent experimental studies on pulp capping in dogs 13 rat submucosal connective tissue 14 repair of root perforation of dog premolar teeth 15 and rat subcutaneous connective tissue 16 . Results obtained in these studies support the idea that both ordinary and white Portland cements have the potential to be used in clinical applications similar to those of MTA because of their physical, chemical and biological properties.…”

Purpose: Clinical, radiological and histological evaluation of root perforations treated with mineral trioxide aggregate (MTA) or Portland cements, and calcium sulfate barrier. Methods: One molar and 11 premolar teeth of a male mongrel dog received endodontic treatment and furcations were perforated with a high-speed round bur and treated with a calcium sulfate barrier. MTA, Portland cement type II (PCII) and type V (PCV), and white Portland cement (WPC) were used as obturation materials. The teeth were restored with composite resin and periapical radiographs were taken. The animal was euthanized 120 days post-surgery for treatment evaluation. RESUMOObjetivo: Avaliar clínica, radiológica e histologicamente perfurações radiculares tratadas com MTA e cimentos Portland, com barreira de sulfato de cálcio. Métodos: A amostra foi constituída por 11 dentes pré-molares e um molar de cão macho, sem raça definida. Após tratamento endodôntico realizaram-se perfurações nas furcas com broca esférica de alta rotação e barreira de sulfato de cálcio. Foram utiliados os cimentos MTA, Portland tipo II (CPII), Portland tipo V (CPV) e Portland branco estrutural (CPB). Os dentes foram restaurados com resina composta e submetidos a radiografias periapicais. O animal foi confinado por 120 dias e submetido à eutanásia para avaliações. Resultados: Primeiro pré-molar inferior direito (MTA), terceiro pré-molar inferior direito (CPV), segundo pré-molar inferior esquerdo (MTA) e segundo pré-molar inferior direito (CPB): clinicamente normal; leve área radiotransparente na furca; pequeno infiltrado inflamatório e neoformação óssea. Terceiro pré-molar inferior esquerdo (CPII), primeiro pré-molar superior direito (CPB), terceiro pré-molar superior direito (CPII) e primeiro molar superior esquerdo (CPV): clinicamente normal; área radiopaca na furca; neoformação óssea. Segundo pré-molar superior direito (MTA), segundo pré-molar superior esquerdo (CPB) e terceiro pré-molar superior esquerdo (CPII): clinicamente com lesão na furca; intensa área radiolucida; infiltrado inflamatório intenso. Conclusão: Todos os cimentos induziram a neoformação óssea.

“…The cytotoxic effect of freshly mixed CGPC was also attributed to the high acidity of the freshly mixed cement (pH 1.6-3.7) when compared to that (pH 5.4-7.3) of the completely set cement [112]. The antimicrobial properties of CGPCs have been investigated in vitro and in vivo [113][114][115][116][117][118][119][120]. It was found that freshly mixed CGPCs inhibited bacterial growth, whereas completely set cement samples revealed no antimicrobial effect.…”

Abstract Glass polyalkenoate cements (GPCs) have been used in dentistry for over 40 years. These novel bioactive materials are the result of a reaction between a finely ground glass (base) and a polymer (acid), usually poly(acrylic acid) (PAA), in the presence of water. This article reviews the types of PAA used as reagents (including how they vary by molar mass, molecular weight, concentration, polydispersity and content) and the way that they control the properties of the conventional GPCs (CGPCs) formulated from them. The article also considers the effect of PAA on the clinical performance of CGPCs, including biocompatibility, rheological and mechanical properties, adhesion, ion release, acid erosion and clinical durability. The review has critically evaluated the literature and clarified the role that the polyacid component of CGPCs plays in setting and maturation. This review will lead to an improved understanding of the chemistry and properties of the PAA phase which will lead to further innovation in the glass-based cements field.
