Dental cavity lining in healthcare refers to the process of placing a thin layer of material, known as a lining, inside a prepared tooth cavity before filling it with a restorative material. The purpose of the lining is to provide a barrier between the tooth structure and the restorative material, and to protect the tooth from further decay. This is done to ensure the longevity of the filling and to prevent the leakage of bacteria and saliva into the tooth.
In healthcare, dental cavity lining is typically used in cases where there is a risk of tooth sensitivity or decay under the filling. The lining material can be made of different materials such as glass ionomer, resin-modified glass ionomer, calcium hydroxide, or other materials. The type of lining material used will depend on the condition of the tooth, the location of the cavity, and the type of filling that will be placed.
Dental cavity lining is typically performed by a general dentist or endodontist and can be done using a dental handpiece and a small brush or a syringe. The lining material is applied to the walls of the prepared cavity and is then cured with a special light. Once the lining has hardened, the filling material is placed and also cured.
It is important for the dental professional to assess the needs of the patient and the condition of the tooth before deciding if a dental cavity lining is necessary. This step is important to ensure the longevity of the filling and to prevent future dental problems.
