vital pulp therapy indications

This process can take anywhere between 6 to 24 months. 814-818. The cause of apical periodontitis is toxic metabolites and byproducts released from microorganisms within the canal and diffused into periapical tissues, eliciting inflammatory responses and bone resorption. : Effects of proinflammatory cytokines on the expression of mineralization markers and heme oxygenase-1 in human pulp cells. 7. 1330-1336. 818-821. Int Endod J 2008; 41: pp. The best sealing agents seem to be MTA or glass ionomer. Control the hemorrhage with a sterile cotton pellet moistened with sterile saline. 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. Teeth that experience luxation-type injuries can discolor and may not respond to cold testing for up to 4 months before they recover normal color and vitality. These procedures are performed routinely in primary and permanent teeth. Int Endod J 2009; 42: pp. As pulpitis progresses, vasoactive neuropeptides contribute to increased vascular permeability and intrapulpal blood flow. Radiographs of carious molars in patients aged 12 to 38 years. Vital pulp therapy is performed to preserve the health status of the tooth and its ultimate position in the arch. : Rel/NF-kappa B/I kappa B family: intimate tales of association and dissociation. Teeth show two distinct layers of carious dentin as the result of gram-positive bacteria releasing lactic acid as their main by-product. A medicament is then placed over the carious dentin to stimulate and encourage pulp recovery. A differential diagnosis based on symptoms and clinical findings is the goal in the assessment of pulp vitality. Differences in the Pulp Related to Age The process is initiated when regenerated odontoblast-like cells recruited from the cell-rich zone and subodontoblastic layer advance the repair of pulpodental defects after migration of highly vascularized tissue to the site. These procedures are performed routinely in 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. 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. Caries excavation followed by placement of a restoration is necessary. 81. Once a tooth is affected by caries, some form of intervention is necessary to prevent further inflammation and ultimately necrosis. 6. The first part of this article provides insight into the basic biology of the dental pulp, the mechanisms involved in inflammation, and the reactions of the pulp to various dental materials at the cellular and molecular level whereas the second part deals with the clinical aspects of treatment of the primary and permanent dentition. Unsatisfactory outcomes for direct capping due to variations in treatment delivery and protocols were clearly demonstrated in a cohort investigation completed by predoctoral dental students. 2. Recent clinical investigations have demonstrated that a diagnosis of symptomatic irreversible pulpitis and acute apical periodontitis may not proscribe pulp capping and pulpotomy procedures when MTA or other CSCs that have been shown to reverse the inflammatory process are used. Int Endod J 2009; 42: pp. Technique 6. 79. : TEGDMA-induced toxicity in human fibroblasts is associated with early and drastic glutathione depletion with subsequent production of oxygen reactive species. One of the primary purposes of the human dental pulp is dentin formation. : Apoptosis induced by the monomers HEMA and TEGDMA involves formation of ROS and differential activation of the MAP-kinases p38, JNK and ERK. : Root canal sealers cause cytotoxicity and oxidative damage in hepatocytes. Nair P.N., Duncan H.F., Pitt Ford T.R., et. Sodium hypochlorite also shows excellent efficacy as a hemostatic agent at lower dilutions (0.5%). The pulp is encased within the dentin. 1. Oral Surg Oral Med Oral Pathol Oral Radiol Endod 2008; 106: pp. (Courtesy Dr. Katharina Bücher and Dr. Jan Kühnisch, Munich, Germany.). Pulpotomy is a vital pulp therapy, medicaments that can promote healing and preserve the vitality of the tooth should be placed after removal of the inflamed pulp. 3. Other studies have reported that calcium hydroxide caused a layer of necrosis of the pulp tissue when used in pulp capping procedures. The use of negative pressure irrigation is highly recommended for safe and proper disinfection. Further reading. An array of extracellular matrix macromolecules regulated by pulp cell activity contributes to tissue differentiation and growth, defense mechanisms, reactions to inflammatory stimuli, and the formation of calcified tissues. Treatment selection is dependent on the extent of remaining healthy pulp tissue, and includes direct pulp capping and partial or complete pulpotomy. In this instance, the coronal and radicular pulps should be removed all the way to the apex of the tooth. § The search to identify and produce the ideal pulp capping material continues, and remarkable progress has been made in pulp preservation research in the past decade. 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. Perhaps of greater importance may be the choice of pulp capping material and the quality of the permanent restoration. 2008. J Endod 2011; 37: pp. : Cytotoxicity comparison of mineral trioxide aggregates and EndoSequence bioceramic root repair materials. The main components of MTA and the new CSCs are tricalcium silicate and dicalcium silicate, major components of Portland cement. al. It is recognized that outcomes for vital pulp therapy can vary, depending on the age of the patient, extent of bacterial contamination, and degree of pulp inflammation. 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. The results of the two studies indicate increasing failure rates over time, attributable to absorption of the material under permanent restorations proximal to mineralized bridges with tunnel defects. 88-94. 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. 156-160. 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. 455-460. 72. Radiographic indications of success do not guarantee a pain-free tooth. 80. Forty-nine teeth were examined in patients aged 7 to 45 years over a 1- to 9-year period, with an average 3.94-year observation time. 5-13. Normal radiographic findings 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. 82. Several studies have questioned the efficacy of caries removal using a caries detector dye. Butler W.T., Bhown M., Brunn J.C., et. 805-820. Historically many different materials have been used for these procedures, including resin-modified glass ionomer cements, tricalcium phosphates, hydrophilic resins, and calcium hydroxide. J Endod 2006; 32: pp. The crystals produced during the calcification process are associated with phosphate and calcium ions, similar to fundamental calcification processes shown by other normal and pathologic calcified tissues. MTA can be considered as an effective material for vital pulp therapy, with the goal of maturogenesis. Depending on the clinical setting, vital pulp therapy can be managed with an indirect or direct pulp-capping procedure.
