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. Friedlander LT, Coates D, Seymour G, Cullinan M, Rich AM. 2018 Nov 21;3(3):153-159. doi: 10.14744/eej.2018.07269. Certain treatments are also used in deciduous teeth, please see 'Endodontic role in Paediatrics' lesson in the Paediatrics topic for more information. They are known as indirect pulp capping and direct pulp capping, and both are used in their own significant circumstances. Apply pressure with a moist sterile cotton pellet on the pulp stump to control hemorrhage. Clinically, vital pulp therapy can be divided into two main groups: indirect pulp capping and direct pulp capping/pulpotomy (Figure 1). Vital pulp therapy is a procedure designed to preserve the vitality of the dental pulp. MTA, BA, or calcium hydroxide is laid over the pulp stump to a thickness of 2–3 mm. 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. 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. Recent research has shown that MTA, when placed in direct contact with the human dental pulp cells, differentiated them into odontoblast-like cells. Caries first comes into contact with the odontoblasts. 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.

Vital pulp therapy (VPT) is a biological approach to minimally invasive endodontics. 2 When decay or tooth preparation extends into the coronal pulp, and the pulp is deemed vital (as described previously), a pulpotomy may be performed. Vital pulp therapy is exactly what it sounds like – treating the pulp in an effort to keep it vital (alive) and leave the patient with a living, pain-free tooth. The ultimate goal for endodontists or dentists is the regeneration of dental pulp for non-vital teeth after pulpectomy or pulp necrosis. The 3- and 12-month success rates of the VPT techniques were comparable in the IPC (98.7% and 100%, respectively), DPC (98.4% and 94.7%, respectively), MP (98.4% and 91.4%, respectively), and FP (93.5% and 95.5%, respectively) arms, respectively (P > .05). INDIRECT PULP CAPPING • Indirect pulp capping is defined as a procedure wherein the deepest layer of the remaining affected carious dentin is covered with a layer of biocompatible material in order to prevent pulpal exposure and further trauma to pulp. Asgary S, Eghbal MJ, Ghoddusi J, Yazdani S. Clin Oral Investig. Epub 2012 Mar 21. Deep carious lesion; Enamel-dentine fracture with no pulpal exposure Results: The panel was unable to make a recommendation on superiority of any particular type of vital pulp therapy owing to lack of studies directly comparing these interventions. As discussed previously, there are various materials that have been tried and tested for pulp capping procedures. When decay or tooth preparation extends into the pulp chamber of the primary incisor or canine, first, an assessment of the vitality of the pulp must be made. It is believed that activation of JNK inhibits cell growth and induces cell death. Aust Endod J. 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. Learn about the types of pulp therapy, risk factors & when treatment is needed. 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. Aluminum Compounds/therapeutic use; Calcium Compounds/therapeutic use 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. 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. NLM 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 procedure is also known as Cvek pulpotomy. Thus, in clinical terms, a necrotic infected pulp is required for apical periodontitis to be present. Vital pulp therapy can be used in immature and fully formed permanent teeth. Types: Indirect pulp cap Indications Deep carious lesion Enamel-dentine fracture with no pulpal exposure firstname.lastname@example.org Vital pulp therapy is performed to preserve the health status of … | 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. Knowing the background about the dental pulp, the various cell types, and their interactions with each other and with various dental materials is important because this could ultimately lead to a better treatment modalities. From a clinical perspective, the control of the hemorrhage is critical to determine the level of pulp inflammation. Failure was defined as the presence of either a clinical symptom (pain, swelling, or fistula) or radiologic abnormality at recall. The radicular pulp chamber may be filled with a resorbable paste of either zinc oxide–eugenol or, preferably, calcium hydroxide with iodoform within the paste. Place calcium hydroxide, MTAs, or BA directly over the exposure site; do not force it into the pulp. Determining whether it’s best to perform vital pulp therapy or orthograde root canal therapy for an individual tooth is a judgment call. Furthermore, GDNF may act as a cell survival factor and mitogen during tooth injury and repair. The continued deposition of dentin occurs throughout the length of the root, providing greater strength and resistance to fracture. For cases of open apexes, maintaining the pulp vital is essential for the development of the root and maturation of the whole tooth. The pulpal and periapical status as well as pulpal exposure type/location had no effect on treatment outcomes. Maintaining deciduous teeth in function until their natural exfoliation is absolutely necessary. Cell poor zone: also called the cell free zone of Weil because it is relatively free of cells. Ultimately, the goal of treating the exposed pulp with an appropriate pulp capping material is to promote the dentinogenic potential of the pulpal cells. Some of the more common restorative materials currently used are resin based. This should be done before the procedure via radiographic assessment or by direct examination of pulp and its color, texture, and bleeding during the procedure. It will also demonstrate how capping materials affect the pulp inflammation and regeneration and the overall outcome of vital pulp therapy. MTA can be considered as an effective material for vital pulp therapy, with the goal of maturogenesis. The activity of NF-κB is tightly regulated by cytokines and other external regulators. 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. The best sealing agents seem to be MTA or glass ionomer. Irreversibly injured odontoblasts are replaced by cells that migrate from this layer. The most important factors in success of VPT are the early diagnosis of pulp and periradicular status, preservation of the pulp vitality and p … Treatment is performed in the appropriate fashion with strict adherence to the proper technique. These cells are important in the defense mechanism of the pulp and have been studied extensively over the past decade. One-year results of vital pulp therapy in permanent molars with irreversible pulpitis: an ongoing multicenter, randomized, non-inferiority clinical trial. J Conserv Dent. Pre- and intraoperative data including vitality test results, pulpal/periapical status, and exposure type/location were recorded. Methods: 7 Many agents have been applicated for direct pulp capping treatment. Vital pulp therapy in permanent teeth . Cell-rich zone: lies subadjacent to the cell-poor zone. vital pulp therapy - by mahak ralli roll no. It is subadjacent to the odontoblastic layer and is traversed by capillaries, unmyelinated nerve fibers, and cytoplasmic processes of fibroblasts. Once a tooth is affected by caries, some form of intervention is necessary to prevent further inflammation and ultimately necrosis. In children and young adults, teeth with traumatic pulp exposure can be treated successfully (96%) with partial pulpotomy and calcium hydroxide. NIH 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. Carious or traumatically exposed primary and permanent teeth, Vital pulp, which responds to sensitivity tests, Limited to moderate restorative treatment. 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. The porosity of this dentinal bridge potentially allows recolonization of bacteria, thereby leading to failure of pulp capping procedures. Vital pulp therapy. 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. 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. Odontoblasts are considered highly specialized cells that have been shown to express Toll-like receptors (TLRs). It is recommended that practitioners gather additional information in each of the referenced areas before engaging in pulp therapy for children. Blinded participants (N = 302) were randomly allocated to 4 study arms. 4.1. In cases of persistent bleeding, partial pulpotomy might be indicated. Copyright © 2017 American Association of Endodontists. Author information: (1)Department of Restorative Dentistry, School of Dentistry, Federal University of Pelotas, Pelotas, Brazil. The pulp is encased within the dentin. Vital pulp therapy with pulp capping. 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. Place calcium hydroxide or glass ionomer directly over the carious region. The presentation will discuss various materials available for use in this procedure. 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. Eghbal MJ, Haeri A, Shahravan A, Kazemi A, Moazami F, Mozayeni MA, Saberi E, Samiei M, Vatanpour M, Akbarzade Baghban A, Fazlyab M, Parhizkar A, Ahmadi M, Akbarian Rad N, Bijari S, Bineshmarvasti D, Davoudi P, Dehghan R, Dehghani M, Ebrahimi H, Emami N, Farajian N, Fereidooni R, Ghobadi G, Ghodrati M, Gohari A, Hashemi A, Hosseini M, Karami E, Kheirabadi N, Kozegari S, Labaf Ghasemi H, Majidi A, Malekzadeh P, Mehrabi V, Mohammadi M, Moradi Eslami L, Noghani A, Omatali N, Pourhatami N, Rahbani Nobar B, Rahmani S, Shafaq P, Soofiabadi S, Teimoori S, Vatandoost F, Asgary S. Pain Res Manag. The crown is then restored with a stainless steel crown, a composite strip crown, or a preveneered, commercially available composite-faced stainless steel crown. The term is frequently used to describe therapy performed to encourage the continuation of this process. Vital pulp therapy in cariously exposed permanent teeth and its limitations. Vital pulp therapy is effective as long as proper assessment of the situation is made. Historically many different materials have been used for these procedures, including resin-modified glass ionomer cements, tricalcium phosphates, hydrophilic resins, and calcium hydroxide. Vital pulp therapy--a review J Ir Dent Assoc. Epub 2012 Feb 6. Vital pulp therapy (VPT) is performed in cases of trauma, caries, and restorative procedures to preserve the vital pulp tissue. National Center for Biotechnology Information, Unable to load your collection due to an error, Unable to load your delegates due to an error. Studies have previously shown that HEMA induces apoptosis in different cell types and also in dental pulp stem cells and in odontoblast-like cells. Cases of permanent tooth mean long-term preservation of the tooth in a healthy state in the mouth. Some molecules, such as TGF-β1, specifically interact with decorin/biglycan in dentine. Vital pulp therapy encompasses apexogenesis, pulpotomy, pulpal debridement, and direct and indirect pulp capping. One of the main causes of inflammation of the pulp is dental caries. Teeth were extracted and then histologically evaluated at 1 week and 2, 3, 4, and 6 months. Types: Indirect pulp cap. Control the hemorrhage with a sterile cotton pellet moistened with sterile saline. Vital pulp therapy can be used in immature and fully formed permanent teeth. 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). When considering the capping material, current evidence in the literature has consistently demonstrated a better outcome when using MTA. da Rosa WLO(1), Piva E(1), da Silva AF(1). Therefore, preservation and treatment of the vital pulp are critical for the prevention of apical periodontitis. Int J Paediatr Dent. 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. In this section, we will discuss the possibility of pulp regeneration therapy for non-vital teeth. 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. Treatment selection is dependent on the extent of remaining healthy pulp tissue, and includes direct pulp capping and partial or complete pulpotomy. Vital pulp therapy for children is simple. 4 Due to advances in science and technology, vital pulp treatment has changed over the last five years in regard to the procedures and materials used. Pain was measured using a numeric rating scale before treatment initiation up to 1 week postoperatively. Pulp therapy removes the decayed tissue to prevent the loss of the tooth or the spread of infection. Endodontics is defined as the branch of dentistry concerned with the morphology, physiology, and pathology of the human dental pulp and periradicular tissues. No layer of necrosis was seen in the pulp when MTA was used for pulp capping. Exposure of the pulp can occur due to caries excavation, trauma, restorative procedures, or anatomical anomalies. Other studies in animal models have shown that MTA down-regulated inflammatory cytokines, such as interferon-gamma, CCL5 (also referred to as regulated on activation, normal T-cell expressed, and secreted [RANTES]), and IL-1α, and suppressed the proliferation of some microorganisms and inhibited the production of certain T h 1 and T h 2 cytokines. 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. In this instance, the coronal and radicular pulps should be removed all the way to the apex of the tooth. Therefore, MTA or equivalent products should be the material of choice for direct pulp capping procedures instead of hard-setting calcium hydroxide cements.
