Secondary dentin is a type of dentin that forms after the tooth has erupted and the root formation is complete, serving as a protective response to stimuli such as tooth wear or caries. It is deposited by odontoblasts and differs from primary dentin in its slower rate of deposition and more irregular structure, contributing to the tooth's defense mechanisms.

Tooth wear is the progressive loss of dental hard tissues caused by factors such as attrition, abrasion, and erosion. It can lead to functional and aesthetic issues if left untreated, necessitating early diagnosis and management to prevent further damage.

Caries, commonly known as tooth decay, is a prevalent oral disease caused by the demineralization of tooth enamel due to acid production from bacterial fermentation of dietary carbohydrates. Effective prevention and management include maintaining oral hygiene, reducing sugar intake, and regular dental check-ups.

Root formation is the process by which a plant develops its root system, essential for anchorage, nutrient absorption, and interaction with soil microorganisms. It involves complex signaling pathways and hormonal regulation, primarily influenced by auxins, cytokinins, and environmental factors such as soil composition and moisture levels.

Odontoblasts are specialized cells located in the dental pulp responsible for the formation of dentin, a calcified tissue that forms the bulk of a tooth. These cells play a crucial role in tooth development and repair by secreting dentin matrix proteins and initiating mineralization processes.
