What causes concrescence of teeth?

What causes concrescence of teeth?

This condition arises as the result of traumatic injury or overcrowding of teeth. True concrescence occurs during root formation phase, whereas acquired concrescence occurs after the radicular phase of development is complete.

What is Gemination and fusion?

Fusion is the union of two embryologically separate developing teeth. Gemination is the incomplete division of a single tooth bud. Fusion presents clinically as a large bifid crown (with a vertical crease).

What is concrescence in dentistry?

Concrescence is a developmental anomaly of dental hard tissues. It is a condition showing union of adjacent teeth by cementum. The concrescence leads to a loss of gingival architecture leading to the development of funnels, which may cause plaque accumulation thus, resulting in periodontal tissue destruction.

What happens in the apposition stage?

The next stage of odontogenesis is the apposition stage, where due to induction between the ectodermal tissue of the enamel organ and mesenchymal tissue of the dental papilla and dental sac will produce of enamel, dentin, and cementum by cellular by-products [1].

What is tooth Gemination?

Abstract. Gemination is an anomaly caused by a single tooth germ that attempted to divide during its development, resulting in a bifid crown. They are found more frequently in the primary than in the permanent dentition unilaterally, but bilateral gemination is very rare.

How are teeth made?

Human teeth are made up of four different types of tissue: pulp, dentin, enamel, and cementum. The pulp is the innermost portion of the tooth and consists of connective tissue , nerves, and blood vessels, which nourish the tooth.

Is dentin or enamel formed first?

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.

Are twin teeth rare?

They are found more frequently in the primary than in the permanent dentition unilaterally, but bilateral gemination is very rare. It is caused by complex interactions among a variety of genetic and environmental factors.

How common are fused baby teeth?

Fusion is a rare developmental disorder characterized by the union of two adjacent teeth at the crown level (enamel and dentin), causing the formation of a tooth with an enlarged clinical crown. Incidence of this anomaly is approximately 0.1% in the permanent and 0.5% in the primary dentition.

What is the difference between a fusion and a gemination?

Gemination is a single enlarged tooth in which the tooth count is normal when the anomalous tooth is counted as one. Fusion is the combining of two tooth germs to form an enlarged tooth.

What is the difference between gemination and Concrescence?

Both gemination and fusion are prevalent in primary dentition, with incisors being more affected. Concrescence is a condition of teeth where the cementum overlying the roots of at least two teeth join together. The cause can sometimes be attributed to trauma or crowding of teeth.

What is the difference between geminated and fused teeth?

Geminated teeth are typically disfigured in appearance due to irregularities of the enamel. Fused teeth can have separated pulpal space, one pulp chamber and two canals or take the form of a large bifid crown with one pulpal space.

What is concrescence of teeth?

Concrescence is a condition of teeth where the cementum overlying the roots of at least two teeth join together. The cause can sometimes be attributed to trauma or crowding of teeth. Surgical separation of the teeth may be necessary if one is to be extracted.
