This document discusses the classification, clinical presentation, diagnosis, and treatment of various types of traumatic dental injuries including concussions, luxations, fractures, and root fractures. It describes the visual signs, sensitivity to percussion, mobility testing, sensitivity testing, radiographic findings, objectives of treatment, and specific treatment approaches for each type of injury. The types of injuries covered include concussions, luxations, enamel fractures, enamel-dentin fractures, enamel-dentin-pulp fractures, crown fractures, crown-root fractures both with and without pulp involvement, and root fractures. Treatment may include repositioning displaced teeth, splinting, monitoring for pulp necrosis, pulp capping, pulpotomy, root canal treatment, extraction
8. â˘Pulp Sensibility Test:
âpositive result
âit is important in assessing
future risk of healing
complications
âlack of response to the test
indicates an increased risk
of later pulp necrosis
