Human tooth missing or diminished enamel on a permanent tooth usually from a prior infection of a nearby primary tooth. Hypoplasia may also result from antineoplastic therapy. Tooth destruction from processes other than dental caries is considered a normal physiologic process but may become severe enough to become a pathologic condition. Attrition is the loss of tooth structure by mechanical forces from opposing teeth. Attrition initially affects the enamel and, if unchecked, may proceed to the underlying dentin. Abrasion is the loss of tooth structure by mechanical forces from a foreign element. If this force begins at the cementoenamel junction, then progression
Dental material of the tooth, the dentist applies a thin layer (approximately 1/2mm) to the base of the tooth, followed by light curing. Another layer might be applied if the cavity is very large and deep. There are many functions to dental lining materials, some of which are listed below: Calcium Hydroxide Calcium Hydroxide has a relatively low compressive strength and a viscous consistency making them difficult to apply to cavities in thick sections, a common technique used to overcome this issue would be to apply a thin sub-lining of a calcium hydroxide lining and then building up with zinc phosphate prior
