Enamel infraction — definition?
A crack in enamel without substance loss.
Enamel fracture — key feature?
Loss of tooth substance, often chipped.
Enamel-dentine fracture — involves?
Both enamel and dentine, pulp unaffected.
Complicated crown fracture — involves?
Enamel, dentine, with pulp exposure.
Root fracture — classified by?
Location: apical, middle, or coronal third.
Luxation injuries — include?
Concussion, subluxation, extrusive, lateral, intrusive.
Supporting bone injury — example?
Alveolar fracture or luxation.
Concussion — tissue affected?
Periodontal ligament, no displacement.
Subluxation — characteristic?
Loosened tooth without displacement.
Extrusive luxation — displacement?
Tooth partially out of socket.
Lateral luxation — displacement?
Tooth displaced sideways, often alveolar fracture.
Intrusive luxation — displacement?
Tooth pushed into alveolar bone.
Alveolar fracture — involves?
Fracture of alveolar process, mobile segment.
Gingival contusion — caused by?
Blunt trauma causing bruise.
Gingival abrasion — result of?
Rubbing or scraping injury.
Gingival laceration — requires?
Suturing for proper healing.
Extraoral exam — assesses?
Facial swelling, bruising, deformity.
Intraoral exam — evaluates?
Soft tissue injuries, mobility, fractures.
Radiographic assessment — key tool?
Detects fractures, foreign bodies, displacements.
Photographic documentation — purpose?
Legal record, treatment planning, monitoring.
Supporting bone injuries — signs?
Mobility, displacement, swelling.
Periodontal injury — includes?
Concussion, luxation, alveolar fracture.
