Epidemiology
2-3 years of age
9-10 years of age
A traumatic dental injury represents the acute transmission of __ to a tooth and its supporting tissues
Energy
There is extensive damage to both cellular and intercellular systems
True
In the initial events of cicatrización it includes
Hemorrhage follow of a coagulation
Late of cicatrization
Revascularization of ischemic tissue and the formation of new tissue
Cuanto tarda en que el new collagen formation begins in the LP to bind the damaged fibers
Leading to the initial healing of a dislocated or reimplanted tooth
A week
In dislocated teeth with damaged vascular supply, the ingrowth of new vessels toward the pulp begins when after the injury
And at what speed aprox in teeth with open apices
4 days after the injury
Speed of 0.5 mm aprox
3 factors that determined new events
- Possible exposure of the dentinal tubules
- Conditions of the pulp, whether it is ischemic and sterile or necrotic and infected
- Presence of adjacent vital cementroblasts
