a material for direct pulp capping, and it has shown good. 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. 11. Increased bleeding is generally associated with inflammation, so that substantial bleeding may indicate extensive infection, which itself is a sign that there is reduced capacity for induced repair of the exposure [1]. However, there was one set of test samples, taken from a plant in the United States (Chandler et al., 1997), that exhibited exceptionally high soundness losses ranging from 10.38% to 14.32% and, as such, surpassed the acceptable limit. Direct pulp capping should not be performed on a pulp that has been exposed as a result of penetrating caries. If pulp tissue is exposed, bleeding will occur from the pulp. 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. 10. 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 … 2019; 12(20):3382. Overall, calcium hydroxide materials appear satisfactory as endodontic sealers in clinical service [47,48], though they are not outstanding in this application [30]. Rutting performance with SSA as a complete filler component was comparable to that of control mixes that used cement, hydrated lime or limestone as fillers, whilst in one case, the addition of 2% SSA to the overall mix led to an improvement in rutting and fatigue. In the present study, 3 capping materials were used and compared in terms of promoting pulp … 10.36 for two test structures, one with a short and one with a longer He diffusion path through SiO2. The success rate registered by us was 82,5% after period of two years follow-up [1, 15, 23 - 29]. For trimer isolation, most of the monomers and dimers were removed along excess CsCl. The properties and clinical performances of four calcium-silicate cements (ProRoot MTA, MTA Angelus, RetroMTA, Biodentine), a light-cured c … Clinically, another critical feature for success in direct pulp capping is the extent of pulp bleeding after the pulp has been exposed and before the direct capping agent has been applied [13–15]. Because of its porosity and absorptive properties, it was most effective when used at 15%, in pulverised form, with water additions to aid the mixing. They can act as direct conduits for contaminant entry from the surface into deeper drinking water aquifers. Nonetheless, the performance of both stability and flow remained within the acceptable limits. 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. Voids in the mix, voids in the aggregate and voids filled with bitumen were comparable to those of the control mixes with SSA as filler and, in line with the stability results, its use as a fine aggregate led to a reduction in the voids. 6.5). However, there has been recent interest in its use as a material for direct pulp capping, and research on this application has been published [19]. Copyright © 2021 Elsevier B.V. or its licensors or contributors. This is because caries penetration is inevitably associated with bacterial invasion, and therefore results in infection and inflammation of the pulp [10]. In addition, following pioneering studies in the late 1970s [31], it has also become used as the main active component of a group of proprietary root canal sealers. However, because of the association of some cases of contact allergy, onychodystrophy, and eczema with ethyl-2-cyanoacrylatenone, these compounds have been accepted as a practicable technique [62]. The material has been evaluated as unbound, hydraulically bound and bituminous bound forms. Pulp-capping Material Life is a hard-set calcium-hydroxide base indicated for use as a direct and indirect pulp-capping material and as a cement base for all restorative filling materials. Direct pulp capping in an immature incisor using a new bioactive material Sham S. Bhat , Sundeep K. Hegde , Fardin Adhikari , and Vidya S. Bhat 1 Department of Paedodontics and Preventive Dentistry, Yenepoya Dental College, Mangalore, Karnataka, India 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. Direct pulp coverage is a minimally invasive procedure, to perform this type of treatment we must first evaluate the case based on clinical and radiographic data, whether a direct pulp coverage or a root canal treatment is needed. Direct pulp capping is a procedure in which an exposed dental pulp is covered with a protective dressing or cement that protects the pulp from ad- ditional injury and permits healing and repair (1). In direct capping with this paste showed no pulp . Direct Pulp Caps. 28,29. 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. Since 2009, a new material based on hydraulic cement chemistry, Biodentine®, has been available for clinical use [20]. The cement is used to act as a liner to provide a reliable seal against the ingress of bacteria, and is needed because calcium hydroxide alone is unable to provide an adequate seal [1]. If the pulp appears infected or symptomatic, the dentist may decide a root canal is the best treatment option. If successful, this procedure precludes the need for more invasive, more extensive and more expensive treatment. The physical properties of calcium hydroxide materials are acceptable for their use as endodontic sealers. Oral Surg Oral Med Oral Pathol. Coupling these features with the high surface area of magnetic NPs has become an important tool to concentrate NPs from environmental samples. The synthesized QDs are hydrophobic and, therefore, cannot be used for biomedical applications.42 The core/shell QDs must be functionalized with secondary coatings or “capping” materials such as mercaptopropionic acid or PEG to improve water solubility and maintain QDs in a nonaggregated state.42 The surface of the functionalized QD can be further conjugated with targeting molecules such as antibodies or receptor ligands as shown in the schematic diagram in Figure 2.1, which allows the QD to be attached to a specific tissue or organ.26 Various applications of biocompatible CdSe/ZnS-QDs have been demonstrated45 such as in vivo imaging of breast cancer in vitro37,41 and imaging of tumor metastases in vivo in mice.58 The CdSe/ZnS-QDs coated with targeting peptides were able to locate and track the tumors with imaging techniques in mice. 11. Advantages of a successful direct pulp capping are numerous, including the avoidance of more extensive treatment, such as root canal treatment or extraction. Coal refuse piles are comprised mainly of the coal shales that encased the coal seam prior to the coal extraction. The literature suggests that either conventional or resin-modified glass-ionomer may be used, though monomer release may occur from the latter type of material, which is potentially damaging, so probably less satisfactory in this application. An application of lime to the overall site at a rate of 55 metric tons/hectare was completed in 2004. The major benefits include good. Materials Used for Direct Pulp Capping: MTA – Mineral Trioxide Aggregate Calcium hydroxide – Calcium Enriched Mixture 10.36. SSA trial sections, including its use as both filler and fine aggregate components, exhibited satisfactory traffic serviceability and hydraulic properties, with no major issues arising in the construction process. Is it worth it? Paula A, Carrilho E, Laranjo M, Abrantes AM, Casalta-Lopes J, Botelho MF, Marto CM, Ferreira MM. Endodontics is the specialty of dentistry that focuses on the management of prevention, diagnosis and treatment of diseases of the dental pulp and periradicular tissues (region around the root of the tooth).. Conclusions.MTA can be a reliable pulp-capping material on direct car-ious exposures in permanent teeth when a two-visit treatment protocol is observed. These cements include zinc oxide-eugenol cements, calcium hydroxide-containing sealers, glass-ionomer cements, polymers, and mineral trioxide aggregate, etc. Chicago/Turabian Style This material causes the formation of a 1–1.5 mm thick necrosis layer in the superficial pulp. Propolis, a resinous material collected by honey bees, has been used as a traditional anti-infalmmatory and anti-bacterial medicine for many centuries. Clinical Protocol: 1. Unfortunately, most new products … Control bleeding with water or saline. I. Inducing reparative tertiary dentin formation by pulp cells has been widely accepted as the ultimate goal of using capping material [ 1 , 2 ]. When the pulp tissue is actually exposed, a direct pulp capping procedure can be performed. Approximately 0.6 m of stabilized FGD were placed and compacted to form an impermeable cap over the regraded site. Any traces of moisture left behind will speed up the setting of calcium hydroxide sealer, allowing it to harden within a few seconds, thus making the insertion of gutta percha points impossible. The layer will undergo calcification eventually and it is called a dentine-bridge. Direct Pulp capping is done mostly when there is accidental exposure of Pulp either by any Trauma or by accidental exposure by the dentist. In the experiment, the test structure is placed in a pure He atmosphere of 1000 mbar for 12 h. Since it is known that He will diffuse through the SiO2 layer, the He pressure in the cavity is 1000 mbar after this dwell time. The direct pulp cap, in which a material is placed directly over the exposed pulp tissue, has been suggested as a way to promote pulp healing and generate reparative dentin. Pulp-capping Material. as a direct pulp-capping material (Fig. Alex G. Direct and indirect pulp capping: a brief history, material innovations, and clinical case report. 18 A successful pulp cap has a vital pulp and a dentin bridge within 75 to 90 days. Direct pulp capping should not be performed on a pulp that has been exposed as a result of penetrating caries. Finally a 0.2 m growing medium consisting of composted yard waste, spoil, and FGD covered the site. It is standard practice to evaluate the resistance of the aggregate to weathering, in the form of sulphate soundness tests. Mineral trioxide aggregate, MTA, has also been used as a direct pulp capping material, though its primary use in dentistry as an endodontic sealer [18]. Pulp capping materials should be able to induce hard-tissue formation in a superficial way, protect the pulp from further invasion of bacteria, and not have side effects so that the pulp can be alive. results in clinical trials. Likewise, few NPs have been separated or concentrated with magnetic NPs as sorbents. Nanoscale ferromagnetic particles are superparamagnetic, getting attracted toward the external magnet and are fine-tuned with surface modification for use as a strong absorbent. First, the affected tooth is isolated from the rest of the mouth to prevent contamination (usually with a thin, flexible barrier called a dental dam), and the decay is removed. TheraCal is a novel light- curable MTA-like material for pulp capping. Endodontics is the specialty of dentistry that focuses on the management of prevention, diagnosis and treatment of diseases of the dental pulp and periradicular tissues (region around the root of the tooth).. (a) Schematic cross-section of the test structure, (b) Measured Q as a function of time during evacuation of a He-filled cavity, for two different lengths of the diffusion path. They flow well in their unset state, so they can reach and seal the apical foramen of the affected tooth, and also adapt to the shape of any irregularities of the dentinal wall. Investigations showed that the incorporation of coal refuse into the resoil mix probably had a greater impact than expected, and boron toxicity resulted when the FGD material placed above the cap came in contact with the low pH coal refuse material. It gives excellent clinical results and is currently typically used in association with some sort of glass-ionomer cement. The pulp is not exposed - a layer of infected dentine is … IV- Pulp capping materials•Calcium Hydroxide Ca (OH)2•Mineral Trioxide Aggregate MTA•Tri-calcium phosphate•Bioaggregate•Biodentine•Bonding Systems 17 18. It was then separated by layering atop the 11 + 62% CsCl gradient with centrifugation for 20 min. Modification of nonmagnetic molecules and ions using chelators such as glutathione and dopamine to superparamagnetic particles has been demonstrated to immobilize and preconcentrate with chemical extraction plus magnetic recovery. Ravindra K. Dhir OBE, ... Ciarán J. Lynn, in Sustainable Construction Materials, 2017. 2018; 39(3):182-189. Direct pulp capping is used when the pulp is exposed after drilling. Direct puip capping The cleaner tooth surface could also conceivably allow better adaptation of the restorative material and hence reduce microleakage (37). 19 The major causes of post-operative inflammation and pulp necrosis are non-sterile procedures and bacterial micro-infiltration of the pulp via dentinal tubules. 9. Life is a hard-set calcium-hydroxide base indicated for use as a direct and indirect pulp-capping material and as a cement base for all restorative filling materials. Because it sets more quickly than MTA, a protective glass-ionomer liner is not needed with this material. It is a hydraulic cement, based on calcium silicate and like calcium hydroxide, it is highly alkaline and this makes it both bactericidal and bioactive. Bahrudeen S. Hameed, ... Anil K. Suresh, in Nanomaterials in Chromatography, 2018. Consequently, the exposed pulp does not become infected or inflamed. Compared with the traditional material of calcium hydroxide, it has superior long-term sealing ability and stimulates a higher Figure 2 Direct pulp-capping technique [9]. By continuing you agree to the use of cookies. Typical cyanoacrylate products contain ethyl cyanoacrylate, isobutyl cyanoacrylate, or N-butyl-cyanoacrylate. Buy Now Dental materials have an important role within endodontics. The article is aimed at analyzing the available research and comparing the properties of bio-inductive materials in direct and indirect pulp capping procedures. Kits. (A) Prior to reclamation. Physiology of the human dental pulp. 18 A successful pulp cap has a vital pulp and a dentin bridge within 75 to 90 days. For the latter materials, their cytotoxicity was attributed to the synergistic effects of the various monomers released by these substances. The result of this experiment is shown in the bottom part of Fig. Priyanka Rani, ... Amit Kumar Nayak, in Applications of Nanocomposite Materials in Dentistry, 2019. It can be used as a replacement for calcium biocompatibility, radiopacity, sealing ability, low solubility, Materials Used in Direct and Indirect Pulp Capping Historically, calcium hydroxide (Ca(OH)2) has been considered the gold standard.Long term clinical observations of calcium hydroxide are incomparable to any other bioactive material, as the Commonly used irrigants and intracanal medicaments include 0.5% sodium hypochlorite solution (as a disinfectant or antimicrobial), EDTA (as a chelating agent and lubricant), chlorhexidine (antimicrobial), non-setting calcium hydroxide (as an antibacterial agent), and some antibiotics and anti-inflammation drugs (non-setting Ledermix paste). 2-4). Scheme of the technique of direct pulp cap-ping “step by step” As a pulp capping material we used mineral triox-ide aggregate (MTA) which is recommended and applied in many newly published scientific studies. Direct pulp capping involves placing a pulp capping material directly over the exposed pulp with the aim of promoting pulp healing and the generation of reparative dentine [1]. Two reviewers independently screened electronic databases (Medline, Central, Embase) and performed hand searches. Calcium hydroxide sealers need to maintain a high degree of integrity in order to remain in place for the necessary time, and ideally should not disintegrate in situ.
