Pulpotomy
Pulpotomy is a minimally invasive procedure performed in children on a primary tooth with extensive caries but without evidence of root pathology. The minimally invasive endodontic techniques of vital pulp therapy (VPT) are based on improved understanding of the capacity of pulp (nerve) tissues to heal and regenerate plus the availability of advanced endodontic materials. During the caries removal, this results in a carious or mechanical pulp exposure (bleeding) from the cavity. During pulpotomy, the inflamed/diseased pulp tissue is removed from the coronal pulp chamber of the tooth leaving healthy pulp tissue which is dressed with a long-term clinically-successful medicament that maintains the survival of the pulp and promotes repair. There are various types of medicament placed above the vital pulp such as Buckley’s Solution of formocresol, ferric sulfate, calcium hydroxide or mineral trioxide aggregate (MTA). MTA is a more recent material used for pulpotomies with a high ra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pulpectomy
Root canal treatment (also known as endodontic therapy, endodontic treatment, or root canal therapy) is a treatment sequence for the infected pulp of a tooth which is intended to result in the elimination of infection and the protection of the decontaminated tooth from future microbial invasion. Root canals, and their associated pulp chamber, are the physical hollows within a tooth that are naturally inhabited by nerve tissue, blood vessels and other cellular entities. Together, these items constitute the dental pulp. Endodontic therapy involves the ''removal'' of these structures, disinfection and the subsequent shaping, cleaning, and decontamination of the hollows with small files and irrigating solutions, and the ''obturation'' (filling) of the decontaminated canals. Filling of the cleaned and decontaminated canals is done with an inert filling such as gutta-percha and typically a zinc oxide eugenol-based cement. Epoxy resin is employed to bind gutta-percha in some ro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mineral Trioxide Aggregate
Mineral trioxide aggregate (MTA) was developed for use as a dental root repair material by Mahmoud Torabinejad. It is formulated from commercial Portland cement, combined with bismuth oxide powder for radio-opacity. MTA is used for creating apical plugs during apexification, repairing root perforations during root canal therapy, and treating internal root resorption. This can be used for root-end filling material and as pulp capping material. Originally, MTA was dark gray in color, but white versions have been on the market since 2002. Portland cement is a term applied to a class of materials covering a range of compositions (between silica alumina and calcia). The composition, fineness, setting time and strength of Portland cement are not controlled or guaranteed. Portland cement is an unsuitable substitute for MTA based on several characteristics that are essential to the performance: freedom from heavy metals, dimensional stability and fineness. The FDA requires dental materials ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Formocresol
Formacresol is a mixture consisting of formalin, cresol and glycerine used in dentistry. It is used for vital pulpotomy of primary teeth and as a temporary intracanal medicament during root canal therapy. Buckley's solution is a 20% form of formocresol, diluted with glycerine and distilled water. The use of formocresol in pediatric dentistry Pediatric dentistry (formerly pedodontics in American English or paedodontics in Commonwealth English) is the branch of dentistry dealing with children from birth through adolescence.

Ferric Sulfate
Iron(III) sulfate (or ferric sulfate), is a family of inorganic compounds with the formula Fe2(SO4)3(H2O)n. A variety of hydrates are known, including the most commonly encountered form of "ferric sulfate". Solutions are used in dyeing as a mordant, and as a coagulant for industrial wastes. Solutions of ferric sulfate are also used in the processing of aluminum and steel. Speciation The various crystalline forms of Fe2(SO4)3(H2O)n are well-defined, often by X-ray crystallography. The nature of the aqueous solutions is often less certain, but aquo-hydroxo complexes such as e(H2O)6sup>3+ and e(H2O)5(OH)sup>5+ are often assumed. Regardless, all such solids and solutions feature ferric ions, each with five unpaired electrons. By virtue of this high spin d5 electronic configuration, these ions are paramagnetic and are weak chromophores. Production Ferric sulfate solutions are usually generated from iron wastes. The actual identity of the iron species is often vague, but many app ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pulpitis
Pulpitis is inflammation of dental pulp tissue. The pulp contains the blood vessels, the nerves, and connective tissue inside a tooth and provides the tooth’s blood and nutrients. Pulpitis is mainly caused by bacterial infection which itself is a secondary development of caries (tooth decay). It manifests itself in the form of a toothache. Signs and symptoms Increased sensitivity to stimuli, specifically hot and cold, is a common symptom of pulpitis. A prolonged throbbing pain may be associated with the disease. However, pulpitis can also occur without any pain. Reversible pulpitis is characterised by intermittent, brief discomfort initiated by a hot, cold or sweet stimulus. The pain evoked is of short duration and there is no lingering or spontaneous pain. The pain ceases within a short period after removal of the stimulus. With a reversible pulpitis, sleep is usually not affected and no analgesics are necessary. Usually, no atypical change is evident on the radiogra ...

Tertiary Dentin
Tertiary dentin (including reparative dentin or sclerotic dentin) forms as a reaction to stimulation, including caries, wear and fractures. Tertiary dentin is therefore a mechanism for a tooth to ‘heal’, with new material formation protecting the pulp chamber and ultimately therefore protects the tooth and individual against abscesses and infection. This form of dentine can be easily distinguished on the surface of a tooth, and is much darker in appearance compared to primary dentine. Tertiary dentine will often not be visible on the surface of a tooth, but because it is more dense it can be viewed on a Micro-CT scan of the tooth. Wear on the surface of a tooth can lead to the exposure of the underlying dentine. When wear is severe tertiary dentine may form to help protect the pulp chamber. Frequency of tertiary dentin in different species of primate suggests teeth 'heal' at different rates in different species. Gorillas have a high rate of tertiary dentin formation, with over ...

Sodium Hypochlorite
Sodium hypochlorite (commonly known in a dilute solution as bleach) is an inorganic chemical compound with the formula NaOCl (or NaClO), comprising a sodium cation () and a hypochlorite anion (or ). It may also be viewed as the sodium salt of hypochlorous acid. The anhydrous compound is unstable and may decompose explosively. It can be crystallized as a pentahydrate ·5, a pale greenish-yellow solid which is not explosive and is stable if kept refrigerated. Sodium hypochlorite is most often encountered as a pale greenish-yellow dilute solution referred to as liquid bleach, which is a household chemical widely used (since the 18th century) as a disinfectant or a bleaching agent. In solution, the compound is unstable and easily decomposes, liberating chlorine, which is the active principle of such products. Sodium hypochlorite is the oldest and still most important chlorine-based bleach. Its corrosive properties, common availability, and reaction products make it ...

Regenerative Endodontics
Regenerative endodontic procedures is defined as biologically based procedures designed to replace damaged structures such as dentin, root structures, and cells of the pulp-dentin complex. This new treatment modality aims to promote normal function of the pulp. It has become an alternative to heal apical periodontitis. Regenerative endodontics is the extension of root canal therapy. Conventional root canal therapy cleans and fills the pulp chamber with biologically inert material after destruction of the pulp due to dental caries, congenital deformity or trauma. Regenerative endodontics instead seeks to replace live tissue in the pulp chamber. The ultimate goal of regenerative endodontic procedures is to regenerate the tissues and the normal function of the dentin-pulp complex. Before this treatment modality is introduced, apexification procedures using either immediate placement of mineral trioxide aggregate apical plug or long term-calcium hydroxide treatment were tradition ...
