Tertiary dentin (including reparative dentin or sclerotic dentin) is a form of dentin, one of the main component materials of teeth. It forms as a reaction to stimulation, including caries , wear and fractures . [ 1 ]
Dentin is classified into three types: primary, secondary, and tertiary. [24] [25] Secondary dentin is a layer of dentin formed after the tooth's root has fully formed. Tertiary dentin develops as a result of a stimulus, such as a carious attack or wear. [26]
Dentin formation, known as dentinogenesis, is the first identifiable feature in the crown stage of tooth development. The formation of dentin must always occur before the formation of enamel. The different stages of dentin formation result in different types of dentin: mantle dentin, primary dentin, secondary dentin, and tertiary dentin. [31]
In animal tooth development, dentinogenesis is the formation of dentin, a substance that forms the majority of teeth. Dentinogenesis is performed by odontoblasts , which are a special type of biological cell on the outer wall of dental pulps , and it begins at the late bell stage of a tooth development .
The progression of pit and fissure caries resembles two triangles with their bases meeting along the junction of enamel and dentin. Teeth are bathed in saliva and have a coating of bacteria on them that continually forms. The development of biofilm begins with pellicle formation. Pellicle is an acellular proteinaceous film which covers the teeth.
There are three types of dentin, primary, secondary and tertiary. [19] Secondary dentin is a layer of dentin produced after root formation and continues to form with age. Tertiary dentin is created in response to stimulus, such as cavities and tooth wear. [20]
Teeth whitening strips are easy-to-use, peel-and-stick strips that you wear on your teeth for 15 to 30 minutes each day. "Most kits come with a 30-day supply and are relatively easy to use," says ...
Odontoblasts also secrete tertiary dentin when irritated. Tertiary dentin secreted by odontoblasts is often due to chemical attack, either by chemicals diffusing through the dentin and insulting the odontoblasts, or by diffusion of toxic bacterial metabolites down the dentinal tubules in the instance of a carious attack with dental decay. This ...
