degeneration and formation of protective … Inducing reparative tertiary dentin formation by pulp cells has been widely accepted as the ultimate goal of using capping material [ 1 , 2 ]. Direct pulp capping should not be performed on a pulp that has been exposed as a result of penetrating caries. It is also used as a medicament for intra-canal treatment and in some apexification procedures [30]. Bahrudeen S. Hameed, ... Anil K. Suresh, in Nanomaterials in Chromatography, 2018. Advantages of a successful direct pulp capping are numerous, including the avoidance of more extensive treatment, such as root canal treatment or extraction. 28,29. direct contact with) pulp, their use as direct pulp capping agents is generally contraindicated in the literature.1,29,37,38 Clearly, the remaining dentin thickness, which is very difficult to access clinically, has an effect on the pulpal response to any indirect pulp capping material.38 The … 10.36. Endodontic materials are used in endodontic treatment, which is the procedure to save the tooth when the pulp and/or periradicular tissues are injured. It is evident that the bottom ash exhibits low susceptibility to sulphate attack, with soundness loss values ranging from 1.1% to 5.4%, which fall well below the 10% and 12% limits in Chinese and American standards, respectively. 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. They must be used carefully, and in particular all the moisture must be removed from the root canal using paper points of the correct number and width. Pulp capping refers to a dental procedure used to prevent necrosis of dental pulp after an exposure or near exposure at the time of preparation of a cavity, by placing a protective dressing over the pulp. Optimum hemorrhage control is essential for successful outcome of direct pulp capping regardless of the material used. • 4- Bioaggregate. If the pulp appears infected or symptomatic, the dentist may decide a root canal is the best treatment option. Int J Clin Exp Med. As described in Chapter 9, the main use of calcium hydroxide is as a pulp capping material. Coupling these features with the high surface area of magnetic NPs has become an important tool to concentrate NPs from environmental samples. Calcium hydroxide materials have a number of advantages when used in this application. In 1970, Langer et al. Approximately 75% of the cavity was filled with Biodentine™ (Fig. Age of patient, hygiene, localization of the caries, size of pulp exposure and all other clinical and radiograph data should be considered to decide whether to perform direct pulp coverage or endodontic treatment. However, this approach is controversial, because the alkalinity is potentially damaging to the gingiva, and the material would be expected to erode quickly. Chicago/Turabian Style Compend Contin Educ Dent. Water percolating through the piles produces the same type of acidic leachate present in the unreclaimed mines discussed in the last section, but low-permeability stabilized FGD has been shown to be an effective capping material, providing a barrier to the salt and acid migration from the toxic coal refuse to the surface and to limit the surface water infiltration into the pile. 1971;32(1):126-134. In direct capping with this paste showed no pulp . An example of stabilized FGD as a cap material is the Rehoboth refuse pile, which was a 24 ha coal waste site located in Perry County, Ohio. • 3- Tri-calcium phosphate. Nanoscale ferromagnetic particles are superparamagnetic, getting attracted toward the external magnet and are fine-tuned with surface modification for use as a strong absorbent. The environmental assessment revealed that the bituminous binding was beneficial in restricting the leaching behaviour of SSA, with the element leaching concentrations falling below the stringent water quality limits. It also has to be used in association with some sort of glass-ionomer liner, in this case to protect the MTA while it undergoes its prolonged setting process [1]. Van Hassel HJ. Prior to reclamation the runoff from the site caused flooding along roadways and waterways in the general area of the coal refuse material. Alex G. Direct and indirect pulp capping: a brief history, material innovations, and clinical case report. The most surprising piece of information regarded the removal of all the affected dentin prior to pulp capping. Chapter 9 Endodontic materials. By continuing you agree to the use of cookies. Coal refuse piles are comprised mainly of the coal shales that encased the coal seam prior to the coal extraction. Our aim is to evaluate the effects of an injectable silver-doped bioactive glass/chitosan hydrogel (Ag-BG/CS), as a pulp-capping material, and explore the molecular … Experimental disks (diameter, 7 mm; height, 4 mm) were stored in a humified incubator at 37 °C for 48 h. 2018; 39(3):182-189. Trial projects have been undertaken with SSA in bituminous bound road pavement layers in Japan and quite extensively in the United States in the 1980s and 1990s, though it appears that this has been discontinued. Zinc oxide-eugenol, resin-modified glass-ionomer and dental adhesives have all been studied, but all proved to have unacceptable cytotoxicity. 2018; 39(3):182-189. Although Calcium Hydoxide has been proven successful for many years, MTA (Mineral Trioxide Aggregate) is fast becoming the material of choice for direct pulp caps. It is standard practice to evaluate the resistance of the aggregate to weathering, in the form of sulphate soundness tests. The major indications of a successful inflamed-pulp-capping procedure are the formation of a dense calcified dentin barrier and the preservation of healthy pulp tissue concomitant with elimination of inflammation. They can act as direct conduits for contaminant entry from the surface into deeper drinking water aquifers. This sample was separated with the same gradient resulting in an 81% trimer [21]. The following materials have been studied as potential materials for direct pulp capping. Physiology of the human dental pulp. Copyright © 2021 Elsevier B.V. or its licensors or contributors. In addition, old abandoned unplugged steel well casings can deteriorate over time, eventually corroding away due to water • 2- Mineral Trioxide Aggregate MTA. ages as a direct pulp capping material, long term studies have shown results to be unpredictable. A direct pulp cap is done on permanent teeth when the removal of deep decay results in exposing the pulp. Direct pulp capping is generally performed using calcium hydroxide as the main material. Their high pH makes them anti-bacterial [32] and also promotes repair around the sealer through calcification and stimulation of hard tissue development [33].

On the other hand, if there is a direct exposure to the pulp, treatment with direct pulp capping requires careful and specific selection of the pulp capping material. In an investigation, specific clustering of two or three NPs has been done by encapsulating the assembled AuNP clusters with polystyrene-block-poly(acrylic acid), which is still imperfect until the high purity products are isolated.
