Front

is developmental anomaly caused by:

• Obstruction in the eruption path

o Tooth

o Dense bone

o Hypertrophied soft tissue

• Ectopic position of the tooth

Back

IMPACTED TOOTH

Front

Theory dictates that hereditary traits cause the tooth to be impacted

Back

MENDELIAN THEORY

Front

Theory suggests that if patient inherits the big teeth from one parent and small jaws from the other parent then lack of space will result

Back

MENDELIAN THEORY

Front

This theory dictates that evolution plays a role in tooth impaction.

Back

PHYLOGENIC THEORY

Front

It is a theory that suggests the idea of the softer diet today the need for large powerful jaws has decreased and has become to small to accommodate all the teeth

Back

PHYLOGENIC THEORY

Front

Theory stares that teeth become impacted because of interference in growth

Back

ORTHODONTIC THEORY

Front

A theory suggests that anything that interferes with downward forward growth of mandible such as development disease, trauma, systemic disease or local disease

Back

ORTHODONTIC THEORY

Front

A type of indicator due to partially impacted third molars are susceptible to caries because they may prove difficult to clean

Back

DENTAL CARIES

Front

A type of impacted tooth indicator due to Pressure from the erupting third molar can cause resorption of the distal surface of the second molar “Even in situations in which no obvious communication between the mouth and the impacted third molar exists, there may be enough communication to allow for caries initiation
