J Int Soc Prev Community Dent. HEMA-induced apoptosis has been linked to the decrease in intracellular glutathione levels and the production of reactive oxygen species in the cells. In cases of a primary tooth, the length of time for expected life is measured against the expected life of the tooth in the mouth without pulp disease or pulp therapy. Odontoblastic layer: the outermost stratum of cells in a healthy pulp. 3. The best sealing agents seem to be MTA or glass ionomer. This provides the pulp a low-compliance environment and receives its blood supply from the blood vessels that traverse through the apical foramen. eCollection 2018. If the pulp does not bleed at all or bleeds at a hemorrhagic level, it may be infected beyond the coronal pulp, and a pulpectomy may be in order. Epub 2020 Nov 5. Epub 2012 Mar 21. In a retrospective study, Gruythuysen and colleagues examined clinically and radiographically the 3-year survival of teeth treated with indirect pulp therapy performed between 2000 and 2004. If there are signs of early external root resorption, radiolucency beyond the confines of the pulp chamber related to the tooth or other signs of disease, or inadequate tooth structure to support a restoration, the tooth may need to be extracted. Types: Indirect pulp cap. A good rule of thumb limits the diameter of the exposure site to less than 1.5 mm. Further research with the new material, however, is ongoing. The ultimate goal for endodontists or dentists is the regeneration of dental pulp for non-vital teeth after pulpectomy or pulp necrosis. 3 In vital pulp therapy, direct pulp capping is an adequate treatment for conserving the vitality and function of the pulp. Indirect Pulp Therapy Pre- and intraoperative data including vitality test results, pulpal/periapical status, and exposure type/location were recorded. In deep caries management of mature permanent molars, the 4 VPTs were associated with favorable/comparable clinical and radiographic outcomes. MTA can be considered as an effective material for vital pulp therapy, with the goal of maturogenesis. Vital pulp therapy in permanent teeth . 2020 Apr 1;9(4):984. doi: 10.3390/jcm9040984. Another study, by Matsuzaka and colleagues, demonstrated that expression of core binding factor alpha-1 subunit and dentin sialoprotein was higher in the younger pulp whereas the adult pulp demonstrated higher levels of vascular endothelial growth factor and heat shock protein 27. USA.gov. A medicament is then placed over the carious dentin to stimulate and encourage pulp recovery. Vital pulp therapy can be used in immature and fully formed permanent teeth. Pulp tissue can be affected as the result of deep caries lesions and accidental trauma or by preparation techniques used during the restoration of teeth affected by carious lesions (Mattos et al. The groups were homogenous in terms of age, sex, marital status, education, and practitioner; pre- and intraoperative conditions were similar in all arms and did not affect the long-term success. The pulp contains numerous cells types, which include odontoblasts, fibroblasts, macrophages, dendritic cells, lymphocytes, mast cells, and undifferentiated mesenchymal stem cells. It will also demonstrate how capping materials affect the pulp inflammation and regeneration and the overall outcome of vital pulp therapy. When caries has extended into the pulp, vital pulp therapy may be a good treatment option, as long as the tissue is not overly inflamed. Thus, in clinical terms, a necrotic infected pulp is required for apical periodontitis to be present. BA is white nanoparticle ceramic cement with many different applications, like MTA. In this instance, the coronal and radicular pulps should be removed all the way to the apex of the tooth. 2020 Jun 15;10(3):300-308. doi: 10.4103/jispcd.JISPCD_69_19. The cellular components of this layer include mainly macrophages and lymphocytes. Types: Indirect pulp cap Indications Deep carious lesion Enamel-dentine fracture with no pulpal exposure BA has also been shown have antifungal and antibacterial activity. Hence, the second part of this review deals with the clinical aspects of treatment of the primary and permanent dentition. CEM cement; Calcium-enriched mixture; endodontics; periapical periodontitis; pulp capping; pulpitis; pulpotomy; randomized controlled trial. Pulp proper: the central mass of the pulp, which consists of larger blood vessels and nerves. The full spectrum of signals responsible for the induction apoptosis in the cells by HEMA and TEGDMA is not established yet, but it involves several different pathways. The survival rate was 96% for primary molars (mean survival time, 146 weeks) and 93% for permanent teeth (mean survival time, 178 weeks). Vital pulp therapy is a procedure designed to preserve the vitality of the dental pulp.

Therefore, after achieving hemostasis on the radicular pulp orifices, and after using a medicament (if desired), the orifices must be sealed with one of these agents. The crown is then restored with a stainless steel crown, a composite strip crown, or a preveneered, commercially available composite-faced stainless steel crown. Aged dental pulps have various characteristics, which include the following: At the molecular level, one study has shown a decreased expression of connexin 43 and osteocalcin in the aged human pulp, which in turn relates to the decreased viability of the odontoblasts and the pulp cells. When considering the capping material, current evidence in the literature has consistently demonstrated a better outcome when using MTA. Once a tooth is affected by caries, some form of intervention is necessary to prevent further inflammation and ultimately necrosis. As with a primary anterior tooth, when there is disease beyond the confines of the tooth related to the tooth, consideration for extraction must be given. Irreversibly injured odontoblasts are replaced by cells that migrate from this layer. Vascularity and VEGF/VEGFR2 Signaling in the Dentine-Pulp Complex of Immature and Mature Permanent Teeth. Would you like email updates of new search results? It is a highly specialized layer for the synthesis and secretion of the organic components of the dentin and has an epithelial layer that serves as a liner for the dental pulp. The mature pulp demonstrates 4 morphologic zones, including. Although not specifically discussed, effective local anesthesia and rubber dam usage are always required. Asgary S, Eghbal MJ, Ghoddusi J, Yazdani S. Clin Oral Investig. Exposure of the pulp can occur due to caries excavation, trauma, restorative procedures, or anatomical anomalies. Vital pulp therapy is performed to preserve the health status of the tooth and its ultimate position in the arch. Odontoblasts are considered highly specialized cells that have been shown to express Toll-like receptors (TLRs). Author information: (1)Department of Restorative Dentistry, School of Dentistry, Federal University of Pelotas, Pelotas, Brazil. Removal of caries may cause cessation of the inflammation but there is a continuous production of these proinflammatory cytokines, which could lead to irreversible pulpal damage followed by necrosis.  |  This study shows that indirect pulp therapy performed in primary and permanent teeth of young patients may result in a high 3-year survival rate. Success of pulpotomy in mature permanent teeth with irreversible pulpitis: A systematic review. Nair and colleagues also demonstrated decreased inflammation when MTA was used compared with calcium hydroxide. Strassler HE(1), Levin R. Author information: (1)Department of Restorative Dentistry, University of Maryland Dental School, USA. Vital pulp therapy is performed to preserve the health status of the tooth and its ultimate position in the arch. Studies have previously shown that HEMA induces apoptosis in different cell types and also in dental pulp stem cells and in odontoblast-like cells. Friedlander LT, Coates D, Seymour G, Cullinan M, Rich AM. Calcium hydroxide has been considered the gold standard for pulp capping; however, previous research has shown that it is not ideally suited for this procedure. VPT is a wide term including indirect pulp capping, direct pulp capping, pulp debridement, pulpotomy, and apexogenesis. Some of the more common restorative materials currently used are resin based. The activity of NF-κB is tightly regulated by cytokines and other external regulators. In this case, after removing the tooth decay, a therapeutic and biocompatible material that prevents infection and heals the pulp is placed over the affected area and then the tooth is restored with a normal filling material. Other studies have demonstrated that HEMA causes increased phophorylation of extracellular-signal-regulated kinases (ERK 1 and 2) and decreased phosphorylation of phosphokinase B (p-AKT). Vital pulp therapy (VPT) is a biological approach to minimally invasive endodontics. Long-term outcomes of pulpotomy in permanent teeth with irreversible pulpitis: A multi-center randomized controlled trial. There is some debate as to whether the remaining radicular pulp orifices should be further treated with a medicament, such as formocresol or ferric sulfate. According to the American Association of Endodontists glossary, apexogenesis is defined as a vital pulp therapy procedure performed to encourage continued physiologic development and formation of the root end. The coronal chamber should be filled with glass ionomer or resin-modified glass ionomer. Generally, sodium hypochlorite has not been used to clean the pulp canals of primary teeth. Cover the capping material with glass ionomer and restore permanently. Caries excavation followed by placement of a restoration is necessary. The term, maturogenesis , was recently introduced by Weisleder and Benitez and defined as physiologic root development not restricted to the apical segment. These procedures offer good alternatives to root canal therapy for teeth with immature or mature apices when pulp is exposed with reversible injury and without signs of inflammation, offering a more conservative approach. Cvek and colleagues investigated the depth of inflammatory reactions of adult monkey pulps exposed by fracture or cavity prep at different time intervals and found that inflammation extended 1.5 mm to 2 mm into the pulp at the 48-hour mark and only 0.8 mm to 2.2 mm after 1 week. This site needs JavaScript to work properly. Cohenca N(1), Paranjpe A, Berg J. Vital pulp therapy--a review J Ir Dent Assoc. Postendodontic Pain after Pulpotomy or Root Canal Treatment in Mature Teeth with Carious Pulp Exposure: A Multicenter Randomized Controlled Trial. Apexification is defined as a method of inducing a calcified barrier in a root with an open apex or the continued apical development of an incompletely formed root in teeth with necrotic pulp. HHS eCollection 2020 May-Jun. Pulpotomy in caries-exposed immature permanent molars using calcium-enriched mixture cement or mineral trioxide aggregate: a randomized clinical trial. Direct pulp capping is defined as the placement of a medicament on a pulp that has been exposed in the course of excavating the last portions of deep dental caries. COVID-19 is an emerging, rapidly evolving situation. Furthermore, GDNF may act as a cell survival factor and mitogen during tooth injury and repair. Random allocation was disregarded when visible pulp exposures did not happen after complete caries removal and the tooth was transferred to the IPC arm. Studies have reported this material to have similar cytotoxicity levels as MTA De-Deus and colleagues found that BA was as biocompatible as MTA and another study reported that BA up-regulated the gene expression of collagen 1, osteocalcin, and osteopontin in osteoblasts and differentiation of human periodontal ligament fibroblasts compared with MTA. The opponents of calcium hydroxide for direct pulp capping procedures cite 3 major causes of failure: The porosity of the dentinal bridge that is produced, Calcium hydroxide adhering poorly to dentin, Inability to provide a long-term seal against microleakage. eCollection 2020. Odontoblasts synthesize mainly type 1 collagen, type V collagen, proteoglycans, dentin sialoprotein, and alkaline phosphatase. Indirect pulp capping has been defined as a procedure in which a small amount of carious dentin is retained in deep areas of cavity preparation to avoid an exposure of the pulp. 2002 Apr;28(1):29-37. doi: 10.1111/j.1747-4477.2002.tb00364.x. Odontoblastic layers appeared earlier; less hyperemia, inflammation, and necrosis were noted; and dentinal bridges were more pronounced in the MTA-treated teeth. A better insight into mechanisms of toxicity of dental materials is important for understanding the potential of these materials to cause adverse health effects in a clinical setting. Clipboard, Search History, and several other advanced features are temporarily unavailable. The literature and standard of care is to use one of these agents (not discussed in this article because of the length limitations); however, there seems to be a directional change toward sealing the orifices completely as the primary objective. Vital pulp therapy with pulp capping. There are several types of pulp therapy. Please enable it to take advantage of the complete set of features! 2018 Nov 21;3(3):153-159. doi: 10.14744/eej.2018.07269. Learn about the types of pulp therapy, risk factors & when treatment is needed. The rationale behind this treatment is the encouragement of young healthy pulps to initiate a dentin bridge and wall off the exposure site.  |  National Center for Biotechnology Information, Unable to load your collection due to an error, Unable to load your delegates due to an error. The structure of the dental pulp is similar to the other connective tissues in the body. Pulpotomy and pulp capping are indicated for teeth that have had a pulp exposure after trauma or injury, which may include the process of caries excavation in developing or mature teeth. Eur Endod J. This is accomplished by sealing the wound against bacterial infiltration, which would otherwise doom the treatment to failure. Another study showed that MTA causes neutrophils to be recruited to the site of injury, which is important in the process of inflammation. Disinfect the pulp wound and cavity with 2% chlorhexidine gluconate. It will exam the use of vital pulp treatment in day to day clinical practice. This review is divided into 2 parts: the first aims to illustrate the basic biology of the pulp and the effects on the pulp due to various procedures; the second focuses on the clinical aspects of treatment and the use of various dental materials during different vital pulp therapy procedures performed in the primary and permanent teeth. Patel and Cohenca also presented a case that demonstrates the use of MTA as a direct pulp capping material for the purpose of continued maturogenesis of the root. If you continue browsing the site, you agree to the use of cookies on this website. The tooth itself, however, is the best space maintainer, and space loss in the primary molar area is a significant long-term issue for patients. Vital pulp therapy (VPT) is a way of saving deciduous teeth. 1 Also known as pulp capping, this procedure is designed to keep the pulp alive, allowing it to heal itself. Vital pulp therapy in cariously exposed permanent teeth and its limitations. 2 At the molecular level, HEMA and TEGDMA have shown to cause cell death/apoptosis in the pulp cells by a decrease in important transcription factors, such as nuclear factor κB (NF-κB) and increase in c-Jun N-terminal kinases (JNK). It is subadjacent to the predentin and is composed of cell bodies of the odontoblasts, capillaries, nerve fibers, and dendritic cells. Keywords: Although TGF-β1 increases the expression and secretion of NGF in human pulp cells, NGF induces mineralization and increases the expression of DSPP and DMP-1. Vital pulp therapy is effective as long as proper assessment of the situation is made. J Conserv Dent. It is likely that recommendations going forward will require sealing the orifices as the main objective. 2. Thus, protection of the pulp by applying capping agents directly or indirectly on pulp tissue is called vital pulp therapies (VPTs) (Da Rosa et al. Using a sterile round bur and/or a sharp spoon, amputate the coronal pulp. During your child’s pulp therapy procedure, our dentist will first visually examine the affected area then take dental X-rays. Blinded participants (N = 302) were randomly allocated to 4 study arms. Disclosing the physiology of pulp tissue for vital pulp therapy. Indirect pulp capping is achieved by applying a protective agent on the thin layer of dentin remaining over a nearly exposed pulp, in order to allow the underlying dental pulp … Introduction: Vital pulp therapy has a high success rate if the following conditions are met: (1) the pulp is not inflamed, (2) hemorrhage is properly controlled, (3) a nontoxic capping material is applied, and (4) the capping material and restoration seal out bacteria. There are two types of pulp therapy: Vital pulp therapy is when only the decayed pulp is removed and the healthy pulp tissue is preserved inside the This article reviews the rudiments of pulp therapy for children. Results: Treatment selection is dependent on the extent of remaining healthy pulp tissue, and includes direct pulp capping and partial or complete pulpotomy. Control the hemorrhage with a sterile cotton pellet moistened with sterile saline. 2020 Mar-Apr;23(2):121-125. doi: 10.4103/JCD.JCD_179_19. Clinically, vital pulp therapy can be divided into two main groups: indirect pulp capping and direct pulp capping/pulpotomy (Figure 1). vital pulp therapy - by mahak ralli roll no. Aeinehchi and colleagues compared the use of MTA and calcium hydroxide in direct pulp capping cases using 11 pairs of third molars (patients 20–25 years old) with pulps mechanically exposed and capped with either MTA or calcium hydroxide, covered with zinc oxide–eugenol, and restored with amalgam.
