“…The contact with MTA may exacerbate discoloration by the incorporation of blood elements (6). Lenherr et al (29) suggest that the porosities of the material may uptake blood components and may be responsible for the observed discoloration.…”

Direct pulp-capping is a method for treating exposed vital pulp with dental material to facilitate the formation of reparative dentin and to maintain vital pulp. Two types of pulp-capping materials, calcium hydroxide and mineral trioxide aggregate, have been most commonly used in clinics, and an adhesive resin has been considered a promising capping material. However, until now, there has been no comprehensive review of these materials. Therefore, in this paper, the composition, working mechanisms and clinical outcome of these types of pulp-capping materials are reviewed.

“…In addition, it is known that for horizontal vibrations, the effect of acceleration amplitude decreases as the void ratio, which is a measure of the porosity in the sample, is reduced [19]. Applying ultrasonic vibrations has been found to be successful in reducing the number of voids in the production of white mineral trioxide aggregate (an endodontic cement), and also increases the density [15,16]. It was also suggested that the ultrasonic frequency and the duration of ultrasonic vibration could affect the arrangement of the particles within the endodontic cement sample [16].…”

Ultrasonic compaction of granular geological materials

It has been shown that the compaction of granular materials for applications such as pharmaceutical tableting and plastic moulding can be enhanced by ultrasonic vibration of the compaction die. Ultrasonic vibrations can reduce the compaction pressure and increase particle fusion, leading to higher strength products. In this paper, the potential benefits of ultrasonics in the compaction of geological granular materials in downhole applications are explored, to gain insight into the effects of ultrasonic vibrations on compaction of different materials commonly encountered in sub-sea drilling. Ultrasonic vibrations are applied, using a resonant 20kHz compactor, to the compaction of loose sand and drill waste cuttings derived from oolitic limestone, clean quartz sandstone, and slate-phyllite. For each material, a higher strain for a given compaction pressure was achieved, with higher sample density compared to that in the case of an absence of ultrasonics. The relationships between the operational parameters of ultrasonic vibration amplitude and true strain rate are explored and shown to be dependent on the physical characteristics of the compacting materials.
