Dentin formed during tooth development and eruption, making up the bulk of the tooth structure.

Dentin deposited slowly throughout life after root formation, leading to narrower pulp chamber and canals.

Defensive reaction that seals off dentinal tubules with calcium deposits, making dentin harder and less permeable.

Emergency dentin formed rapidly in response to injury, protecting the pulp from further damage.

To preserve the vitality of the dentin-pulp complex during cavity preparation and restoration.

Indirect DPP: Actions taken by the dentist to avoid pulp injury. Direct DPP: Materials placed between the tooth and restoration to protect pulp.

Pulp diagnosis, patient age, dentin permeability, cavity depth, restoration type, and patient's occlusion.

Liners stimulate dentinogenesis, have antiseptic properties, and act as chemical and electrical insulators.

They stimulate tertiary dentin formation, have minimal mechanical strength, provide a bacterial barrier, and reduce dentin sensitivity.

Calcium hydroxide (Ca(OH)2) is a white, fine, and odorless powder that is mixed with distilled water.

It has an alkaline pH (bactericidal and bacteriostatic), is soluble, reabsorbs over time, has low compressive and tensile strength, is non-adhesive, and radiopaque.

Settable Calcium Hydroxide: Mixed at a 1:1 ratio, used for indirect pulp protection. Non-Settable Calcium Hydroxide: Used for direct pulp protection.

A white powder composed of hydrophilic particles, mixed in a 3:1 ratio. White MTA differs from grey MTA by removing aluminoferric tetracalcic.

It has a pH of 12.5 (bacteriostatic), promotes dentin regeneration, forms a peripheral seal, is minimally soluble, has a setting time of 3-4 hours.

Calcium Oxide + Water = Calcium Hydroxide (CaOH2). Calcium Hydroxide dissociates into calcium and hydroxyl ions upon contact with fluids.

MTA is used as a pulp protector in cases of pulp exposure or communication with the pulp.

MTA causes less pulp inflammation and forms a thicker and more regular dentin bridge.

An excellent, but expensive, material used for pulp protection and dentin regeneration.

Biodentine is a composite of Zirconium Dioxide (for radiopacity) and Calcium Chloride (for faster setting time).

Tricalcium silicate base → Hydrated calcium silicate gel + Calcium Hydroxide.

Initial setting time is over 6 minutes, final setting time is 12-16 minutes. Setting time can be accelerated by using calcium chloride.

A resin-modified calcium silicate, light-curable material often used as direct and indirect pulp protection.

It uses a hydrophilic monomer, is applied in 1mm layers, requires 20 seconds of light curing, stimulates apatite formation, is easy and fast to apply, releases calcium over time, has a permanent alkaline pH, and provides strong adhesion and sealing.

A self-adhesive, dual-curing base/liner that releases calcium and fluoride, commonly used as a base or liner.

It chemically bonds to the tooth structure, cures dual for deep restorations, offers greater strength and durability than other base materials, is radiopaque, has potential cytotoxicity, and forms a thinner dentin bridge than other calcium silicate materials.

Calcium silicate materials (like MTA) create thicker and more regular dentin bridges compared to Calcium Hydroxide. Theracal LC forms a thinner dentin bridge compared to traditional calcium silicate cements. Biodentine generates the thickest and most consistent dentin bridge.
