In deep caries management of mature permanent molars, the 4 VPTs were associated with favorable/comparable clinical and radiographic outcomes. 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. The radicular orifices are assessed to determine that bleeding can be controlled only by direct pressure with a damp cotton piece for a minute or 2. Clinical and radiographic follow-up demonstrated a vital pulp and physiologic root development in comparison with the contralateral tooth. When considering the capping material, current evidence in the literature has consistently demonstrated a better outcome when using MTA. 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. Accidental pulp exposure during inlay cavity preparation with mechanical instruments in an upper molar; the pulp appears vital, with no bleeding Fig. Some of the more common restorative materials currently used are resin based. Therefore, MTA or equivalent products should be the material of choice for direct pulp capping procedures instead of hard-setting calcium hydroxide cements. Disclosing the physiology of pulp tissue for vital pulp therapy. Clipboard, Search History, and several other advanced features are temporarily unavailable. HHS No layer of necrosis was seen in the pulp when MTA was used for pulp capping. Friedlander LT, Coates D, Seymour G, Cullinan M, Rich AM. Blinded participants (N = 302) were randomly allocated to 4 study arms. Deep carious lesion; Enamel-dentine fracture with no pulpal exposure No correlations were found between healing and size of pulp exposure, type of trauma, time frame, and root development. Caries excavation followed by placement of a restoration is necessary. Odontoblastic layer: the outermost stratum of cells in a healthy pulp. Vital pulp therapy can be used in immature and fully formed permanent teeth. HEMA-induced apoptosis has been linked to the decrease in intracellular glutathione levels and the production of reactive oxygen species in the cells. Hence, the second part of this review deals with the clinical aspects of treatment of the primary and permanent dentition. Vital pulp therapy can be used in immature and fully formed permanent teeth. This site needs JavaScript to work properly. Aust Endod J. Doumani MD, Arnous WA, Alsafadi MF, Alnazer HA, Alanazi SM, Alotaibi KS, Al-Ammari AI. Nair and colleagues also demonstrated decreased inflammation when MTA was used compared with calcium hydroxide. 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. 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. There are several types of pulp therapy. Would you like email updates of new search results? 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. Introduction: From a clinical perspective, the control of the hemorrhage is critical to determine the level of pulp inflammation. 7 Many agents have been applicated for direct pulp capping treatment. Vascularity and VEGF/VEGFR2 Signaling in the Dentine-Pulp Complex of Immature and Mature Permanent Teeth. 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. 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. Vital pulp therapy (VPT) is performed in cases of trauma, caries, and restorative procedures to preserve the vital pulp tissue. Thus, to be effective, calcium hydroxide needs to be in contact with noninflamed tissue located approximately 2 mm of pulp beneath exposure site. 1 Also known as pulp capping, this procedure is designed to keep the pulp alive, allowing it to heal itself. NLM hstrassler@umaryland.edu PMID: 23189909 [Indexed for MEDLINE] Publication Types: Case Reports; MeSH terms. 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. Apply pressure with a moist sterile cotton pellet on the pulp stump to control hemorrhage. COVID-19 is an emerging, rapidly evolving situation. Certain treatments are also used in deciduous teeth, please see 'Endodontic role in Paediatrics' lesson in the Paediatrics topic for more information. Aluminum Compounds/therapeutic use; Calcium Compounds/therapeutic use Strassler HE(1), Levin R. Author information: (1)Department of Restorative Dentistry, University of Maryland Dental School, USA. Wound Lavage in Studies on Vital Pulp Therapy of Permanent Teeth with Carious Exposures: A Qualitative Systematic Review. A medicament is then placed over the carious dentin to stimulate and encourage pulp recovery. A good rule of thumb limits the diameter of the exposure site to less than 1.5 mm. 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. 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. Int J Paediatr Dent. Author information: (1)Department of Endodontics, School of Dentistry, University of Washington, Seattle, WA 98195-7448, USA. For cases of open apexes, maintaining the pulp vital is essential for the development of the root and maturation of the whole tooth. 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. 2013 Mar;17(2):431-9. doi: 10.1007/s00784-012-0712-6. eCollection 2020. Long-term outcomes of pulpotomy in permanent teeth with irreversible pulpitis: A multi-center randomized controlled trial. 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. There are two common types of vital pulp therapy: Indirect pulp cap and direct pulp cap: Sometimes the decay on a child’s tooth is close to or just touching the pulp. Vital pulp therapy with new materials for primary teeth: new directions and Treatment perspectives. The connective tissue in this zone contains collagen fibers and ground substance. 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. 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). When decay or tooth preparation extends into the coronal pulp, and the pulp is deemed vital (as described previously), a pulpotomy may be performed. VPT is a wide term including indirect pulp capping, direct pulp capping, pulp debridement, pulpotomy, and apexogenesis. Resin monomers, such as 2-hydroxyethyl methacrylate (HEMA) and triethyleneglycol dimethacrylate (TEGDMA), are shown to influence the differentiation of human pulp cells into odontoblasts. 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. cohenca@u.washington.edu Vital pulp therapy is performed to preserve the health status of …  |  2020 Jun 30;2020:5853412. doi: 10.1155/2020/5853412. Disinfect the cavity using 2.5% sodium hypochlorite for at least 1 minute. According to the American Association of Endodontists glossary, partial pulpotomy is defined as the removal of a small portion of the vital coronal pulp as a means of preserving the remaining coronal and radicular pulp tissues to encourage continued physiologic development and formation of the root end. It will exam the use of vital pulp treatment in day to day clinical practice. Vital pulp therapy for children is simple. NIH These cells are important in the defense mechanism of the pulp and have been studied extensively over the past decade. 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). It has a higher number of fibroblasts with more in the central region of the pulp. 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. MTA, BA, or calcium hydroxide is laid over the pulp stump to a thickness of 2–3 mm. 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. Vital pulp therapy is performed to preserve the health status of the tooth and its ultimate position in the arch. Epub 2020 Nov 5. Determining whether it’s best to perform vital pulp therapy or orthograde root canal therapy for an individual tooth is a judgment call. 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. Types: Indirect pulp cap Indications Deep carious lesion Enamel-dentine fracture with no pulpal exposure 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. Clinically, vital pulp therapy can be divided into two main groups: indirect pulp capping and direct pulp capping/pulpotomy (Figure 1). Historically many different materials have been used for these procedures, including resin-modified glass ionomer cements, tricalcium phosphates, hydrophilic resins, and calcium hydroxide. Classfication • It may be – Direct pulp therapy – Indirect Pulp therapy • Its also classified as • Vital pulp therapy – Indirect pulp capping (IPC) – Direct Pulp Caping (DPC) – Pulpotomy – Pupectomy – Apexogenesis • Non-vital therapy – Apexofication – SCAP (stem cell of apical papilla) facebook.com/notesdental. Learn about the types of pulp therapy, risk factors & when treatment is needed. 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. Vital pulp therapy. The most important factors in success of VPT are the early diagnosis of pulp and periradicular status, preservation of the pulp vitality and p … Asgary S, Eghbal MJ, Ghoddusi J, Yazdani S. Clin Oral Investig. There is evidence to show that odontoblasts play an active role in innate immunity. Pulp proper: the central mass of the pulp, which consists of larger blood vessels and nerves. 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. Author information: (1)Department of Restorative Dentistry, School of Dentistry, Federal University of Pelotas, Pelotas, Brazil. TLR-2 and TLR-4 have been immune-localized in human odontoblasts. 2020 Mar-Apr;23(2):121-125. doi: 10.4103/JCD.JCD_179_19. In this section, we will discuss the possibility of pulp regeneration therapy for non-vital teeth. eCollection 2020 May-Jun. BA is white nanoparticle ceramic cement with many different applications, like MTA. Odontoblastic layers appeared earlier; less hyperemia, inflammation, and necrosis were noted; and dentinal bridges were more pronounced in the MTA-treated teeth. Participants were followed up for 1 year. Another pulp capping material recently developed is mineral trioxide aggregate (MTA). Studies have previously shown that HEMA induces apoptosis in different cell types and also in dental pulp stem cells and in odontoblast-like cells. Place calcium hydroxide or glass ionomer directly over the carious region. This randomized clinical trial aimed to evaluate and compare clinical and radiographic success of 4 VPTs (indirect pulp capping [IPC], direct pulp capping [DPC], miniature pulpotomy [MP], and full pulpotomy [FP]) using calcium-enriched mixture cement for deep caries management of mature permanent molars including teeth with clinical signs of irreversible pulpitis and the presence of apical periodontitis. 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. Keywords: In our opinion, extraction is not the correct alternative treatment plan for these patients. 2020 Jun 15;10(3):300-308. doi: 10.4103/jispcd.JISPCD_69_19. Another study showed that MTA causes neutrophils to be recruited to the site of injury, which is important in the process of inflammation. 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. However, pulpotomy and pulpectomy are the most popular procedures. 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. This article reviews the rudiments of pulp therapy for children. The activity of NF-κB is tightly regulated by cytokines and other external regulators. 42 iv/i Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. Historically, the material used during pulp capping procedures has been calcium hydroxide. 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. During your child’s pulp therapy procedure, our dentist will first visually examine the affected area then take dental X-rays. Remove all peripheral caries before removing the deepest caries. The continued deposition of dentin occurs throughout the length of the root, providing greater strength and resistance to fracture. 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. Pre- and intraoperative data including vitality test results, pulpal/periapical status, and exposure type/location were recorded. Although the use of these materials is aesthetically appealing in patients, they carry the risk of local and systemic adverse effects. Vital pulp therapy is performed to preserve the health status of the tooth and its ultimate position in the arch. The paste is condensed into the radicular pulp chamber after careful pulp extirpation, cleaning of the canal, and irrigation with saline. This randomized clinical trial aimed to evaluate and compare clinical and radiographic success of 4 VPTs (indirect pulp capping [IPC], direct pulp capping [DPC], miniature pulpotomy [MP], and full pulpotomy [FP]) using calcium-enriched mixture cement for deep caries management of mature permanent molars including teeth with clinical signs of irreversible pulpitis and the presence of apical … 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. Exposure of the pulp can occur due to caries excavation, trauma, restorative procedures, or anatomical anomalies. 2013 Jan;23(1):56-63. doi: 10.1111/j.1365-263X.2012.01224.x. Types: Indirect pulp cap. Treatment is performed in the appropriate fashion with strict adherence to the proper technique. 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. 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. A material that further seals, such as glass ionomer or resin-modified glass ionomer, should then be used to fill the coronal pulp chamber. As discussed previously, there are various materials that have been tried and tested for pulp capping procedures. Ultimately, the goal of treating the exposed pulp with an appropriate pulp capping material is to promote the dentinogenic potential of the pulpal cells. Epub 2012 Feb 6.

Maintaining deciduous teeth in function until their natural exfoliation is absolutely necessary. Vital pulp therapy encompasses apexogenesis, pulpotomy, pulpal debridement, and direct and indirect pulp capping. Odontoblasts are considered highly specialized cells that have been shown to express Toll-like receptors (TLRs). 2002 Apr;28(1):29-37. doi: 10.1111/j.1747-4477.2002.tb00364.x. The crown is then restored with a stainless steel crown, a composite strip crown, or a preveneered, commercially available composite-faced stainless steel crown. 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. The structure of the dental pulp is similar to the other connective tissues in the body. Disinfect the pulp wound and cavity with 2% chlorhexidine gluconate. 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. Vital pulp therapy is effective as long as proper assessment of the situation is made. 3. In cases of persistent bleeding, partial pulpotomy might be indicated. Cell-rich zone: lies subadjacent to the cell-poor zone. Endodontics is defined as the branch of dentistry concerned with the morphology, physiology, and pathology of the human dental pulp and periradicular tissues. Mechanically or traumatically exposed primary and young permanent teeth, No history of spontaneous or irreversible inflamed pulp, Radiographic evidence of pulpal or periradicular pathosis, Exposures with purulent or serous exudates. 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. After baseline pain adjustment, pain relief was continuous with similar patterns in all treatment groups. Cases of permanent tooth mean long-term preservation of the tooth in a healthy state in the mouth. 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. J Clin Med. Success of pulpotomy in mature permanent teeth with irreversible pulpitis: A systematic review. There are two major forms of vital pulp therapy. 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. 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. 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.
