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. 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. 1 Maintaining the vitality of dental pulp increases a tooth’s mechanical resistance and long-term survival. Vital pulp therapy is effective as long as proper assessment of the situation is made. Vital permanent teeth with cariously exposed pulp can be treated successfully with vital pulp therapy. As discussed previously, there are various materials that have been tried and tested for pulp capping procedures. There is evidence to show that odontoblasts play an active role in innate immunity. 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. The American Association of Endodontists (AAE) Consensus Conference Recommended Diagnostic Terminology states that mature permanent teeth clinically diagnosed with irreversible pulpitis are treated with pulpectomy and root canal filling because inflamed vital pulp is not capable of healing. 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. It has been recommended that vital pulp treatment should be performed only in young patients 2 , 51 , 52 because of the high healing capacity of pulp tissue in young patients in comparison with old patients. Vital pulp therapy in permanent teeth 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. Using a sterile round bur and/or a sharp spoon, amputate the coronal pulp.  |  The continued deposition of dentin occurs throughout the length of the root, providing greater strength and resistance to fracture. Vital pulp therapy (VPT) is primarily indicated for immature permanent teeth with reversible pulpitis caused by mechanical pulp exposure during carious excavation or operative procedure, or a traumatic pulp exposure of healthy teeth with minimal bacterial contamination 3, 4. HHS Vital pulp therapy for children is simple. 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. 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. When considering the capping material, current evidence in the literature has consistently demonstrated a better outcome when using MTA. Coronal pulpotomy for cariously exposed permanent posterior teeth with closed apices: A systematic review and meta-analysis. It is likely that recommendations going forward will require sealing the orifices as the main objective. In terms of bacterial penetration, Kakoli and colleagues showed that bacterial infection of the dentinal tubules occurs to a lesser extent in older patients than in younger patients. Electronic database MEDLINE via Ovid, PubMed, and Cochrane databases were searched. In children and young adults, teeth with traumatic pulp exposure can be treated successfully (96%) with partial pulpotomy and calcium hydroxide.

Especially in young permanent teeth with immature roots, the pulp is … Objectives: To encourage the formation of a protective hard tissue barrier following injury. Akhlaghi N, Khademi A: Outcomes of vital pulp therapy in permanent teeth with different medicaments based on review of the literature. The paste is condensed into the radicular pulp chamber after careful pulp extirpation, cleaning of the canal, and irrigation with saline. The main functions of the pulp include (1) formation of dentin and (2) nutrition to the dentin, which is avascular, protective, and reparative. Krakow AA, Berk H, Gron P. Therapeutic induction of root formation in the exposed incompletely formed tooth with vital pulp. Place calcium hydroxide, MTAs, or BA directly over the exposure site; do not force it into the pulp. The rationale behind this treatment is the encouragement of young healthy pulps to initiate a dentin bridge and wall off the exposure site. 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. NLM Vitality of dental pulp is essential for long-term tooth survival. Ali AH, Thani FB, Foschi F, Banerjee A, Mannocci F. J Clin Med. Current best evidence provides inconclusive information regarding factors influencing treatment outcome, and this emphasizes the need for further observational studies of high quality. Clean canal walls with moistened sterile cotton pellet. primary teeth, cellspulp therapy T he aim of vital pulp therapy is to treat reversible pulpal injuries in both permanent and primary teeth, maintaining pulp vitality and function(1). Vital pulp therapy in adult permanent teeth with cariously exposed pulp is controversial. The porosity of this dentinal bridge potentially allows recolonization of bacteria, thereby leading to failure of pulp capping procedures. Indirect pulp therapy: an alternative to pulpotomy in primary teeth. 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). Copyright © 2011 American Association of Endodontists. Conclusions: NF-κB is the major transcription factor that is involved in the regulation of a variety of genes responsible for survival of the cells. HEMA-induced apoptosis has been linked to the decrease in intracellular glutathione levels and the production of reactive oxygen species in the cells. 11. OOO 1977; 43: 755-765 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. Self-Limiting versus Rotary Subjective Carious Tissue Removal: A Randomized Controlled Clinical Trial-2-Year Results. J Endod. The Vital Pulp Therapy of Permanent Teeth: A Dental Practitioner's Perspective from Saudi Arabia. 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. The key to the success of vital pulp therapy … Disinfect the pulp wound and cavity with 2% chlorhexidine gluconate. Indications for Vital Pulp Therapy. 2020 Jun 15;10(3):300-308. doi: 10.4103/jispcd.JISPCD_69_19. J Int Soc Prev Community Dent. 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. It is recommended that practitioners gather additional information in each of the referenced areas before engaging in pulp therapy for children. Preserving the pulp is important in the treatment of carious pulp exposure in young permanent teeth. JNK belongs to the family of mitogen-activated protein kinases that comprise of a group of serine/threonine kinases, which are responsible for phosphorylation and mediation of signal transduction from extracellular stimuli. 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. Vital pulp therapy can be used in immature and fully formed 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. Recently a new material has been introduced, BioAggregate (BA) (Innovative BioCeramix, Vancouver, British Columbia, Canada). A stainless steel crown is the restoration of choice after performing a primary molar pulpotomy. 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). On the molecular level, MTA has been shown to induce the secretion of angiogenic factors, such as vascular endothelial growth factor, which plays an important role in healing. This provides the pulp a low-compliance environment and receives its blood supply from the blood vessels that traverse through the apical foramen. Odontoblastic layers appeared earlier; less hyperemia, inflammation, and necrosis were noted; and dentinal bridges were more pronounced in the MTA-treated teeth. Vital pulp therapy Pulp capping Indirect pulp capping [ICP] Direct pulp capping [DCP] Pulpotomy Apexogenesis 7. 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. Other studies had given a lower prognosis to indirect pulp therapy, however, especially in permanent teeth. 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. 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. Vital pulp therapies are the treatment of choice for traumatized and carious teeth with vital pulps and open apices [17]. New approches in vital pulp therapy in permanent teeth. 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. Elmsmari F, Ruiz XF, Miró Q, Feijoo-Pato N, Durán-Sindreu F, Olivieri JG. Epub 2015 Dec 10. 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. Studies have previously shown that HEMA induces apoptosis in different cell types and also in dental pulp stem cells and in odontoblast-like cells. 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. Alqaderi H, Lee CT, Borzangy S, Pagonis TC. The ultimate endodontics goal could be defined, however, as the prevention and/or elimination of apical periodontitis. A medicament is then placed over the carious dentin to stimulate and encourage pulp recovery. 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. The aim of vital pulp therapy is to maintain healthy pulp tissue by eliminating bacteria from the dentin-pulp complex. History, clinical evaluation and radiographic findings should be integrated to arrive at pulp diagnosis. Some of the more common restorative materials currently used are resin based. 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. Clipboard, Search History, and several other advanced features are temporarily unavailable. 2020 Sep;21(3):112-113. doi: 10.1038/s41432-020-0128-0. No layer of necrosis was seen in the pulp when MTA was used for pulp capping. USA.gov. Therefore, preservation and treatment of the vital pulp are critical for the prevention of apical periodontitis. 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 Cover the capping material with glass ionomer and restore permanently. 2020 Aug 31;17(17):6340. doi: 10.3390/ijerph17176340. 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. 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. 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. 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. TLR-2 and TLR-4 have been immune-localized in human odontoblasts. No history of spontaneous, lingering, or severe pain, No extensive restoration or full crown requirements, History of spontaneous pain or signs of irreversible pulpitis, Clinical or radiographic evidence of pulpal or periradicular pathosis, Tooth requires extensive restoration or full crown. Maintaining pulpal health is essential for the longevity of a tooth.1 It is, therefore, important that caries be controlled promptly and a well-sealing restoration be placed immediately. All statistics were performed by STATA version 10. This material has drawn much interest due to its many applications. 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. Results: Third, primary teeth are space maintainers for permanent successor eruption, maintain arch length and help to guide permanent dentition into place. For cases of open apexes, maintaining the pulp vital is essential for the development of the root and maturation of the whole tooth. Evaluation of Resin-Based Material Containing Copaiba Oleoresin (. [Article in Polish] Makowiecki P, Trusewicz M, Tyszler L, Buczkowska-Radlińska J. Cell poor zone: also called the cell free zone of Weil because it is relatively free of cells. Vital pulp therapy with new materials: new directions and treatment perspectives—permanent teeth. Published by Elsevier Inc. All rights reserved. Although not specifically discussed, effective local anesthesia and rubber dam usage are always required. 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. Hand searching was performed through reference lists of endodontic textbooks, endodontic-related journals, and relevant articles from electronic searching. Hand searching was performed through reference lists of endodontic textbooks, endodontic-related … The potential risks are direct damage to the cells (cytotoxicity) and induction of immune-based hypersensitivity reactions. Apply pressure with a moist sterile cotton pellet on the pulp stump to control hemorrhage. 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. 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%). Further research with the new material, however, is ongoing. Vitality of dental pulp is essential for long-term tooth survival. Pulpotomy treatment is a very common form of vital pulp therapy. After placement of a layer of resin-modified glass ionomer as liner over carious dentin, the teeth were restored. It is subadjacent to the odontoblastic layer and is traversed by capillaries, unmyelinated nerve fibers, and cytoplasmic processes of fibroblasts. The odontoblasts have odontoblastic processes that extend into the dentinal tubules and occupy most of the space of the dentinal tubules. Some studies have reported that the pulp has some physiologic feedback mechanisms to counteract inflammation and increased tissue pressure, which in turn explains why inflammation of the pulp could be long standing and could heal if appropriate measures are taken in a timely manner. Because the answer involves multiple factors such as understanding the complex nature of the carious disease, knowing the pathological state inside the pulp, and recognizing the capabilities and the limits of the biomaterials in stimulating repair. 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. Vital pulp therapy is performed to preserve the health status of the tooth and its ultimate position in the arch. Resin monomers, such as 2-hydroxyethyl methacrylate (HEMA) and triethyleneglycol dimethacrylate (TEGDMA), are shown to influence the differentiation of human pulp cells into odontoblasts. 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. Once a tooth is affected by caries, some form of intervention is necessary to prevent further inflammation and ultimately necrosis. The best sealing agents seem to be MTA or glass ionomer. These procedures are performed routinely in primary and permanent teeth. Pulp-dentin regeneration: current state and future prospects. 2012 Nov;143(11):1232-3. doi: 10.14219/jada.archive.2012.0069. The pulp contains numerous cells types, which include odontoblasts, fibroblasts, macrophages, dendritic cells, lymphocytes, mast cells, and undifferentiated mesenchymal stem cells. Partial pulpotomy and full pulpotomy sustained a high success rate up to more than 3 years (partial pulpotomy: >6 months-1 year, 97.6%; >1-2 years, 97.5%; >2-3 years, 97.6%; and >3 years, 99.4%; full pulpotomy: >6 months-1 year, 94%; >1-2 years, 94.9%; >2-3 years, 96.9%; and >3 years, 99.3%). • Accepted endodontic therapy for primary teeth can be divided into two categories: vital pulp therapy (VPT) and root canal treatment (RCT). 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. BA is white nanoparticle ceramic cement with many different applications, like MTA. 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. 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 .
