The term is frequently used to describe therapy performed to encourage the continuation of this process. The entire coronal pulp is removed circumferentially with a large round bur, pulling coronally to adequately deroof the pulp chamber and to avoid leaving any ledges or pulp tissue therein. 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. Using a sterile round bur and/or a sharp spoon, amputate the coronal pulp. When considering the capping material, current evidence in the literature has consistently demonstrated a better outcome when using MTA. Evaluation of Resin-Based Material Containing Copaiba Oleoresin (. It is expected that the teeth will maintain vitality with resolution of symptoms (if present) and completion of root development in immature teeth after vital pulp therapy. Epub 2015 Dec 10. Historically, the material used during pulp capping procedures has been calcium hydroxide. Current best evidence provides inconclusive information regarding factors influencing treatment outcome, and this emphasizes the need for further observational studies of high quality. The procedure is also known as Cvek pulpotomy. MTA has demonstrated significantly greater frequency of dentin bridge formation, thicker and less porous dentin, and less pulp inflammation compared with calcium hydroxide. The paste is condensed into the radicular pulp chamber after careful pulp extirpation, cleaning of the canal, and irrigation with saline. Results: It is likely that recommendations going forward will require sealing the orifices as the main objective. MTA, BA, or calcium hydroxide is laid over the pulp stump to a thickness of 2–3 mm. Vital pulp therapy for primary teeth diagnosed with ab normal pulp or reversible pulpitis Protective liner A protective liner is a thinly-applied liquid placed on the pulpal surface of a deep cavity preparation, covering exposed dentin tubules, to act as a protective barrier between the restorative material or cement and the pulp. Caries excavation followed by placement of a restoration is necessary. Vital pulp therapy Pulp capping Indirect pulp capping [ICP] Direct pulp capping [DCP] Pulpotomy Apexogenesis 7. A stainless steel crown is the restoration of choice after performing a primary molar pulpotomy. Pulp tissue is necessary for tooth nutrition, innervation and immunocompetency. Vital pulp therapy (VPT) is performed in cases of trauma, caries, and restorative procedures to preserve the vital pulp tissue. Cell-rich zone: lies subadjacent to the cell-poor zone. Aust Endod J. 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. A medicament is then placed over the carious dentin to stimulate and encourage pulp recovery. It has a higher number of fibroblasts with more in the central region of the pulp. In this article, several aspects of vital pulp therapy (VPT) in permanent teeth from diagnosis and indications to treatment outcomes will be discussed in detail. Recent research has shown that MTA, when placed in direct contact with the human dental pulp cells, differentiated them into odontoblast-like cells. Resin monomers, such as 2-hydroxyethyl methacrylate (HEMA) and triethyleneglycol dimethacrylate (TEGDMA), are shown to influence the differentiation of human pulp cells into odontoblasts. A Combination of Full Pulpotomy and Chairside CAD/CAM Endocrown to Treat Teeth with Deep Carious Lesions and Pulpitis in a Single Session: A Preliminary Study. The vitality of dental pulp is essential for long-term tooth survival. 2 Vital pulp therapy is performed to preserve and maintain the health of the pulpal tissue in cases of exposure due to trauma, caries and/or restorative procedures. MTA was clinically easier to use as a direct pulp capping agent and resulted in less pulpal inflammation and more predictable hard tissue barrier formation than Dycal. Therefore, preservation and treatment of the vital pulp are critical for the prevention of apical periodontitis. A material that further seals, such as glass ionomer or resin-modified glass ionomer, should then be used to fill the coronal pulp chamber. IEJ Iranian Endodontic Journal 2014;9(4):295-300 Outcomes of Different Vital Pulp Therapy Techniques on Symptomatic Permanent Teeth: A Case Series Saeed Asgary a, Mahta Fazlyab b, Sedigheh Sabbagh b*, Mohammad Jafar Eghbal b a Iranian Center for Endodontic Research, Research Institute of Dental Sciences, Shahid Beheshti University of Medical Sciences, Tehran, Iran; b Dental Research Introduction: This systematic review aims to illustrate the outcome of vital pulp therapy, namely direct pulp capping, partial pulpotomy, and full pulpotomy, in vital permanent teeth with cariously exposed pulp.  |  USA.gov. 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. 2015;94(11):1544-1551. Generally, sodium hypochlorite has not been used to clean the pulp canals of primary teeth. Pulpotomy is a vital pulp therapy in which a portion of the coronal pulp tissue is surgically removed, and the remaining radicular tissue is covered with suitable material that protects the pulp from further injury and permits and promotes healing. Research: The authors stated that more well-designed observational studies of the methods of treating vital permanent teeth … A good rule of thumb limits the diameter of the exposure site to less than 1.5 mm. Couto RSD, Rodrigues MFSD, Ferreira LS, Diniz IMA, Silva FS, Lopez TCC, Lima RR, Marques MM. When decay or tooth preparation extends into the coronal pulp, and the pulp is deemed vital (as described previously), a pulpotomy may be performed. 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. Certain treatments are also used in deciduous teeth, please see 'Endodontic role in Paediatrics' lesson in the Paediatrics topic for more information. There is evidence to show that odontoblasts play an active role in innate immunity. In a different randomized clinical study, Nair and colleagues investigated the pulpal response to direct pulp capping in healthy human teeth with MTA versus calcium hydroxide cement (Dycal) as control. If the caries does progress to the pulp, it leads to inflammation, which is caused by several proinflammatory cytokines, such as interleukin (IL)-1β and tumor necrosis factor α, and chemokines, which cause cell death, increased vascular permeability, and an increase in inflammatory cells into the area along with production of acute phase proteins. Conclusions: Thus, in clinical terms, a necrotic infected pulp is required for apical periodontitis to be present. Apply pressure with a moist sterile cotton pellet on the pulp stump to control hemorrhage. The investigators concluded that the defense system in younger pulps was accomplished by calcification and in adult pulp is performed by self-defense proteins and regeneration of vessels. 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. A protective liner is a thinly-applied liquid placed on the pulpal surface of a deep cavity preparation, covering exposed dentin tubules, to act as a protective barrier between the restorative material or cement and the pulp. 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). eCollection 2020 May-Jun. Place calcium hydroxide or glass ionomer directly over the carious region. IL-1β has been shown to induce the synthesis of collagen, resulting in a more organized response of the pulp and assisting in the healing process. There are several different treatment options for vital pulp therapy in extensively decayed or traumatized teeth. The pulp contains numerous cells types, which include odontoblasts, fibroblasts, macrophages, dendritic cells, lymphocytes, mast cells, and undifferentiated mesenchymal stem cells. 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. Another study showed that MTA causes neutrophils to be recruited to the site of injury, which is important in the process of inflammation. Historically many different materials have been used for these procedures, including resin-modified glass ionomer cements, tricalcium phosphates, hydrophilic resins, and calcium hydroxide. BA has also been shown have antifungal and antibacterial activity. OOO 1977; 43: 755-765 Vital pulp therapy procedures like partial (Cvek) pulpotomy and full pulpotomy (in anterior and posterior teeth) are discussed in the first section. In addition to these, in primary teeth it is important to preserve the tooth until its … Although not specifically discussed, effective local anesthesia and rubber dam usage are always required. 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. Odontoblasts synthesize mainly type 1 collagen, type V collagen, proteoglycans, dentin sialoprotein, and alkaline phosphatase. Vital pulp therapy Restoring the Tooth’s own heartbeat 6. 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. Electronic database MEDLINE via Ovid, PubMed, and Cochrane databases were searched. Iran Endod J 2014; 9(1): 15-22. Disinfect the pulp wound and cavity with 2% chlorhexidine gluconate. 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. Caries first comes into contact with the odontoblasts. The odontoblasts are particularly important because they are responsible for dentinogenesis both during tooth development and in the mature tooth. 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. The pulp is encased within the dentin. Odontoblastic layers appeared earlier; less hyperemia, inflammation, and necrosis were noted; and dentinal bridges were more pronounced in the MTA-treated teeth. If there is the ability to retain the tooth in the mouth via pulpectomy and careful monitoring of the tooth to reduce or eliminate local infection, while waiting for a permanent molar to erupt (in the case of second primary molar infection), this treatment option may be performed with careful monitoring as a transitional treatment. Vital pulp therapy is performed to preserve the health status of the tooth and its ultimate position in the arch for the expected life of the tooth. Preserving the pulp is important in the treatment of carious pulp exposure in young permanent teeth. [Article in Polish] Makowiecki P, Trusewicz M, Tyszler L, Buczkowska-Radlińska J. Pulp-dentin regeneration: current state and future prospects. J Am Dent Assoc. Copyright © 2011 American Association of Endodontists. Disinfect the cavity using 2.5% sodium hypochlorite for at least 1 minute. The porosity of this dentinal bridge potentially allows recolonization of bacteria, thereby leading to failure of pulp capping procedures. From a clinical perspective, the control of the hemorrhage is critical to determine the level of pulp inflammation. The question about the exact indications and contraindications of vital pulp therapy in permanent teeth never settled down. J Endod. Because a vital, functioning pulp is capable of initiating several defence mechanisms to protect the body from bacterial invasion, it is beneficial to preserve the vitality and health of an exposed pulp rather than replace it with a root filling material following pulp exposure. Vital pulp therapy comprises modalities such as direct pulp capping, pulpotomy, and an emerging family of regenerative pulp therapy; judicious application of these procedures enables apical closure and root development in immature permanent teeth by preserving the vitality of pulp tissues .

At the cellular level, MTA has also been shown to induce the recruitment and proliferation of undifferentiated cells to form a dentinal bridge, while reducing inflammation compared with calcium hydroxide. It is subadjacent to the odontoblastic layer and is traversed by capillaries, unmyelinated nerve fibers, and cytoplasmic processes of fibroblasts. Clipboard, Search History, and several other advanced features are temporarily unavailable. The fluctuation of the success rate of direct pulp capping was observed (>6 months-1 year, 87.5%; >1-2 years, 95.4%; >2-3 years, 87.7%; and >3 years, 72.9%). The ultimate endodontics goal could be defined, however, as the prevention and/or elimination of apical periodontitis. In 1987, Fuks and colleagues performed partial pulpotomy on 63 teeth with different types and severity of traumatic injuries and demonstrated a 94% success rate. Pulpotomy treatment is a very common form of vital pulp therapy. This site needs JavaScript to work properly. Embryologically, histologically, and functionally, the dentin and the pulp are the same and are considered together, which is why they are also referred to as the pulp-dentin complex. The success of different pulp capping materials has been measured by thickness of the dentinal bridge, morphology of the dentinal bridge, intensity of pulpal inflammation, presence of odontoblasts cells, and biocompatibility. Coronal pulpotomy for cariously exposed permanent posterior teeth with closed apices: A systematic review and meta-analysis. Vital pulp therapy in cariously exposed permanent teeth and its limitations. Ultimately, the goal of treating the exposed pulp with an appropriate pulp capping material is to promote the dentinogenic potential of the pulpal cells. Vital pulp therapy with new materials: new directions and treatment perspectives—permanent teeth. 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. Witherspoon DE. With the development of more biocompatible materials with high sealing properties, these teeth might have a better outcome with direct pulp therapy. COVID-19 is an emerging, rapidly evolving situation. For cases of open apexes, maintaining the pulp vital is essential for the development of the root and maturation of the whole tooth. This systematic review aims to illustrate the outcome of vital pulp therapy, namely direct pulp capping, partial pulpotomy, and full pulpotomy, in vital permanent teeth with cariously exposed pulp. It is recommended that practitioners gather additional information in each of the referenced areas before engaging in pulp therapy for children. HEMA-induced apoptosis has been linked to the decrease in intracellular glutathione levels and the production of reactive oxygen species in the cells. 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. Indirect pulp therapy: an alternative to pulpotomy in primary teeth. Inflammation is a tightly regulated process and its main function is to eliminate pathogens and remove damaged tissue with the aim of restoring tissue homeostasis. The primary goal of pulp therapy is to maintain the integrity and health of the teeth and their supporting tissues while maintaining the vitality of the pulp of a tooth affected by caries, traumatic injury, or other causes. 12. TLR-2 and TLR-4 have been immune-localized in human odontoblasts. Some studies have shown that the processes are limited to the inner third of the dentin and other studies have demonstrate the processes extending to the dentinoenamel junction. The best sealing agents seem to be MTA or glass ionomer. NF-κB is the major transcription factor that is involved in the regulation of a variety of genes responsible for survival of the cells. Vital pulp therapy is an umbrella term describing four main techniques, these are indirect pulp capping, direct pulp capping and pulpotomy, which can be partial or complete. NIH Cases of permanent tooth mean long-term preservation of the tooth in a healthy state in the mouth. The teeth will be followed up both clinically and radiographically for 1 year after treatment. Further research with the new material, however, is ongoing. Outcome of Partial Pulpotomy in Cariously Exposed Posterior Permanent Teeth: A Systematic Review and Meta-analysis. Canals should be cleaned carefully but not significantly instrumented (primary roots are narrow and curved and there is a risk of perforation or extension beyond the apex). 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). Another pulp capping material recently developed is mineral trioxide aggregate (MTA). Vitality of dental pulp is essential for long-term tooth survival. Similar to MTA, this material induced secretion of IL-1β, IL-6, and IL-8. Other studies had given a lower prognosis to indirect pulp therapy, however, especially in permanent teeth. Conversely, if the pulp is vital, there should be few or no bacteria present in the root pulp space and thus the disease (apical periodontitis) should not be present. Int J Environ Res Public Health. In cases of persistent bleeding, partial pulpotomy might be indicated. Basic Concepts In Vital Pulp Therapy Of Cariously Exposed Permanent Teeth The treatment objective following pulp exposure is to obtain healing of a pulp wound in order to preserve a vital tooth with a healthy pulp. Studies have previously shown that HEMA induces apoptosis in different cell types and also in dental pulp stem cells and in odontoblast-like cells. Vital pulp therapy. As discussed previously, there are various materials that have been tried and tested for pulp capping procedures. The term, maturogenesis , was recently introduced by Weisleder and Benitez and defined as physiologic root development not restricted to the apical segment. Teeth were extracted and then histologically evaluated at 1 week and 2, 3, 4, and 6 months. Young permanent teeth Vital pulp therapy for teeth diagnosed with a normal pulp or reversible pulpitis Protective liner. Types: 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.  |  • The functions of primary teeth are: mastication and function, esthetics, speech development, and maintenance of arch space for permanent teeth. The tooth pulp is a unique organ and is encased in a protective layer of dentin, which is encased by a layer of the enamel. The continued deposition of dentin occurs throughout the length of the root, providing greater strength and resistance to fracture. As the pulp is important for tooth nutrition, innervations, and immunocompetency, the maintaining of this precious tissue increases a tooth' mechanical resistance and survival rate. 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. This provides the pulp a low-compliance environment and receives its blood supply from the blood vessels that traverse through the apical foramen. The rationale behind this treatment is the encouragement of young healthy pulps to initiate a dentin bridge and wall off the exposure site. Odontoblastic layer: the outermost stratum of cells in a healthy pulp. Remove all peripheral caries before removing the deepest caries. Endodontics is defined as the branch of dentistry concerned with the morphology, physiology, and pathology of the human dental pulp and periradicular tissues. History, clinical evaluation and radiographic findings should be integrated to arrive at pulp diagnosis. 2020 Jun 15;10(3):300-308. doi: 10.4103/jispcd.JISPCD_69_19. Treatment. Vital pulp therapy can be used in immature and fully formed permanent teeth. 2016 Jan;44:1-7. doi: 10.1016/j.jdent.2015.12.005. There are several different treatment options for vital pulp Indirect Pulp Capping • a procedure in which a material is placed on a thin partition of remaining carious dentin that, if removed, might expose the pulp in immature permanent teeth. National Center for Biotechnology Information, Unable to load your collection due to an error, Unable to load your delegates due to an error. BA is white nanoparticle ceramic cement with many different applications, like MTA. The aim of pulp therapy in primary and young permanent teeth is to maintain a functional tooth so that arch integrity is preserved in a growing child. • deep carious lesions where caries excavation was conservative and direct pulp exposures were avoided • either Ca(OH)2 or zinc oxide–eugenol (ZOE) in a one- or two-stage procedure. Cell poor zone: also called the cell free zone of Weil because it is relatively free of cells. Akhlaghi N, Khademi A: Outcomes of vital pulp therapy in permanent teeth with different medicaments based on review of the literature. The structure of the dental pulp is similar to the other connective tissues in the body. HHS 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. All statistics were performed by STATA version 10. • Accepted endodontic therapy for primary teeth can be divided into two categories: vital pulp therapy (VPT) and root canal treatment (RCT).
