“…Sunnegardh et al observed a similar problem for calcium aluminate cement [131]. Its heterogeneous microstructure and surface porosity limited its polishability, compared to resin composite and polyacid-modiﬁed resin composite [132]. Higher porosity (80% as opposed to 58%) decreased mechanical properties of porous poly( l -lactide-co- d , l -lactide) scaffolds: compressive strength decreased from 11.0 to 2.7 MPa and modulus from 168.3 to 43.5 MPa [133].…”

The connective hard tissues bone and teeth are highly porous on a micrometer scale, but show high values of compression strength at a relatively low weight. The fabrication of porous materials has been actively researched and different processes have been developed that vary in preparation complexity and also in the type of porous material that they produce. Methodologies are available for determination of pore properties. The purpose of the paper is to give an overview of these methods, the role of porosity in natural porous materials and the effect of pore properties on the living tissues. The minimum pore size required to allow the ingrowth of mineralized tissue seems to be in the order of 50 µm: larger pore sizes seem to improve speed and depth of penetration of mineralized tissues into the biomaterial, but on the other hand impair the mechanical properties. The optimal pore size is therefore dependent on the application and the used material.

The study aimed to assess the changes of the surface roughness induced by some acidic beverages on indirect restorative materials by using profilometry. Twenty samples of three composite resins (Ceramage, SR Adoro, Luna-Wing) and three ceramics (IPS In Line, Hera Ceram, Reflex Dimension) immersed in three acidic beverages (Red Bul, wine, Coca Cola), for 5 minutes, three times daily, 14 days. The control samples were immersed in artificial saliva during the study periode. After the end of the erosive cycles and before to determine the surface roughness of the samples in the study groups, all the samples were immersed in artificial saliva for 18 hours. The surface roughness was determined in relation to the baseline surface using profilometer Perthometer_M1 (Mahr Gottingen GmbH, Germany). The immersion of the indirect restorative materials tested in the three acidic beverages lead has resulted to changes in their surface roughness. The most aggressive was wine, followed by Coca Cola, and Red Bull.

“…Sunnegårdh-Grönberg et al also evaluated the physical properties of DD in a series of publications. [7][8][9] The aim of the first study was to compare a new ceramic restorative cement for posterior restorations, DD, with other types of tooth-colored materials for direct use as regards to hardness and in vitro wear. 7 Four hybrid resin composites (RCs)-one polyacid-modified RC, one resin-modified glass ionomer (RMGI) cement, one conventional glass ionomer cement (GIC), and one zinc phosphate cement, an experimental version as well as the marketed version of the ceramic restorative cement-were investigated.…”

This second part (Part II) of a two-part comprehensive review of bioactive and biomimetic restorative materials reviews the calcium aluminate-based restorative dental materials. Part II explores the development, composition, properties, and application of the bioactive calcium aluminate-based materials that have been developed for several indications in restorative dentistry. CLINICAL SIGNIFICANCEBioactive materials have evolved over the past three decades from relatively specialized, highly biocompatible, but low-strength dental materials to now emerge in product compositions for expanded clinical uses in restorative dentistry. Further developments to meet additional restorative clinical needs are anticipated in the newly emerging category of dental materials. (J Esthet Restor Dent 26:27-39, 2014) CALCIUM ALUMINATE CEMENTS Similar to the calcium silicate cements (CSCs), the calcium aluminate cements (CAC) are also derived from the class of cements called "hydraulic" or natural cements. Their hydrating solution is water with 30 to 90 ppm lithium to accelerate the hardening process. A typical CAC contains prereacted constituents as follows: Al2O3 = 43%; CaO = 19%; H2O = 15%; ZrO2 = 19% (silicon, iron, magnesium, titanium, and alkali oxides less than 10%). The calcium aluminate undergoes very rapid hydration with a setting reaction at a pH of 11.4 to 12.5 and the formation of the reaction products Katoite and Gibbsite. Mechanistically, water dissolves the calcium aluminate powder with the subsequent formation of calcium ions calcium ions (Ca 2+ ), aluminum hydroxyl ions (Al(OH)4 -, and hydroxyl ions (OH -). This activity is then followed almost immediately by precipitation of new solid phases (Katoite and Gibbsite) as the solution reaches saturation. These precipitates grow until they meet, and a connected cluster of hydroxide particles is formed continually. Crystallization of the phases proceeds and the hydrates grow in size from nanometers (nm) to microns (μm). This segment is the second part (Part II) of a two-part comprehensive review of bioactive and biomimetic restorative materials. Part I considered the calciumsilicate-based dental materials. Part II will now review the calcium aluminate-based restorative dental materials.
