Temporary Restoration
Temporary restoration is a temporary filling of a prepared tooth until permanent restoration is carried out. It is used to cover the prepared part of the tooth, in order to maintain the occlusal space and the contact points, and insulation of the pulpal tissues and maintenance of the periodontal relationship. Permanent restoration isn't always done after tooth preparation; it can be done simply to prepare for indirect restoration such as inlays and onlays. Temporary fillings are also used for 'stabilization' techniques where many restorations are needed, and the problem may become worse before it can be fully treated. In these cases, temporary fillings are placed in order to stop progression. Although temporary restorations are only meant to be worn for a few weeks, proper care is required to ensure they stay in place. As with any restoration, proper oral hygiene, including brushing and flossing at least twice a day and rinsing with fluoride-containing fluids, is necessary to ...

Tooth Preparation
Dental restoration, dental fillings, or simply fillings are treatments used to restore the function, integrity, and morphology of missing tooth structure resulting from caries or external trauma as well as the replacement of such structure supported by dental implants. They are of two broad types—''direct'' and ''indirect''—and are further classified by location and size. Root canal therapy, for example, is a restorative technique used to fill the space where the dental pulp normally resides and are more hectic than a normal filling. History In Italy evidence dated to the Paleolithic, around 13,000 years ago, points to bitumen used to fill a tooth and in Neolithic Slovenia, 6500 years ago, beeswax was used to close a fracture in a tooth. Graeco-Roman literature, such as Pliny the Elder's Naturalis Historia (AD 23–79), contains references to filling materials for hollow teeth.

Pulp (tooth)
The pulp is the connective tissue, nerves, blood vessels, and odontoblasts that comprise the innermost layer of a tooth. The pulp's activity and signalling processes regulate its behaviour. Anatomy The pulp is the neurovascular bundle central to each tooth, permanent tooth, permanent or primary tooth, primary. It is composed of a central pulp chamber, pulp horns, and radicular canals. The large mass of the pulp is contained within the pulp chamber, which is contained in and mimics the overall shape of the crown of the tooth.Fehrenbach, MJ. and Popowics, T. (2026), ''Illustrated Dental Embryology, Histology, and Anatomy'', Elsevier, page 185-86. Because of the continuous deposition of the dentine, the pulp chamber becomes smaller with the age. This is not uniform throughout the coronal pulp but progresses faster on the floor than on the roof or sidewalls. Radicular pulp canals extend down from the cervical region of the crown to the Root apex (dental), root apex. They are not ...

Periodontics
Periodontology or periodontics (from Ancient Greek , – 'around'; and , – 'tooth', genitive , ) is the specialty of dentistry that studies supporting structures of teeth, as well as diseases and conditions that affect them. The supporting tissues are known as the periodontium, which includes the gingiva (gums), alveolar bone, cementum, and the periodontal ligament. A periodontist is a dentist that specializes in the prevention, diagnosis and treatment of periodontal disease and in the placement of dental implants. The periodontium The term ''periodontium'' is used to describe the group of structures that directly surround, support and protect the teeth. The periodontium is composed largely of the gingival tissue and the supporting bone. Gingivae Normal gingiva may range in color from light coral pink to heavily pigmented. The soft tissues and connective fibres that cover and protect the underlying cementum, periodontal ligament and alveolar bone are known as the gingiv ...

Inlays And Onlays
In dentistry, inlays and onlays are used to fill cavities, and then cemented in place in the tooth. This is an alternative to a direct restoration, made out of composite, amalgam or glass ionomer, that is built up within the mouth.Inlays and onlays are used in molars or premolars, when the tooth has experienced too much damage to support a basic filling, but not so much damage that a crown is necessary. The key comparison between them is the amount and part of the tooth that they cover. An inlay will incorporate the pits and fissures of a tooth, mainly encompassing the chewing surface between the cusps. An onlay will involve one or more cusps being covered. If all cusps and the entire surface of the tooth is covered this is then known as a crown. Historically inlays and onlays will have been made from gold and this material is still commonly used today. Alternative materials such as porcelain were first described being used for inlays back in 1857. Due to its tooth like colour ...

Zinc Oxide Eugenol
Zinc oxide eugenol (ZOE) is a material created by the combination of zinc oxide and eugenol contained in clove oil. An acid–base reaction takes place with the formation of zinc eugenolate chelate. The reaction is catalysed by water and is accelerated by the presence of metal salts. ZOE can be used as a dental filling material or dental cement in dentistry.Jack L. Ferracane, ''Materials in Dentistry: Principles and Applications'', 2001, 2d Edition, Lippincott Williams & Wilkins, Richard van Noort, 2002, ''Introduction to Dental Materials'', 2d Edition, Elsevier Health Sciences, It is often used in dentistry when the decay is very deep or very close to the nerve or pulp chamber. Because the tissue inside the tooth, i.e. the pulp, reacts badly to the drilling stimulus (heat and vibration), it frequently becomes severely inflamed and precipitates a condition called acute or chronic pulpitis. This condition usually leads to severe chronic tooth sensitivity or actual toothache and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
