Gnarled Enamel

Gnarled Enamel

Question 1. Gnarled enamel.
Answer:

On the axial surfaces of teeth, the rods are usually straight and parallel to each other.

• But over the cusps of teeth, the rods are straight and parallel for a short distance from the surface, but at the DEJ, the rods appear twisted around each other in a complex arrangement known as gnarled enamel.

Gnarled enamel Significance:

• Gnarled enamel is a functional adaptation of enamel rods in the cuspal area where excessive load is applied.
• It indicates that the ameloblast has initially an irregular course during early amelogenesis.

Question 2. The formative phase of ameloblast.
Answer:

• The formative phase is the third stage in the life cycle of ameloblast.
• It occurs after the formation of the first layer of dentin.
• The dentin is necessary for the enamel matrix formation.
• During this stage, ameloblasts retain the same length and arrangement.
• But changes occur in the organization and number of cytoplasmic organelles.

• Development of blunt cell process on the ameloblast surfaces occurs.
• This process penetrates the basal lamina and enters the presentation.
• Dentin formation occurs due to the differentiation of odontoblasts.
• This occurs due to close contact of the epithelial cells with the connective tissue of the pulp.
• It is followed by the maturative stage.
• During it, most of the enamel matrix has been formed in the occlusal or incisal area.
• But it still continues in the cervical area.
• Next, morphological changes occur even in the ameloblast as they closely attach to the enamel matrix.
