Dental Trauma by Mind Map: Dental Trauma

1. Etiology

1.1. Fall injuries

1.2. Automobile accident

1.3. Injury due to convulsive seizure

1.4. Child abuse

1.5. Foreign body hitting the oral structure

2. Predisposing factors

2.1. Child activity

2.2. Child motor coordination

2.2.1. learning to walk

2.2.2. medical problem ( mental , physical retardation)

2.3. Occlusion:

2.3.1. open bite : protrusion of upper centrals & insufficient lip closure

3. Diagnosis

3.1. history,

3.1.1. Medical history

3.1.2. Dental History When Where How

3.2. examination

3.2.1. Intraoral Soft tissue: laceration or foreign body Each Tooth: Fracture ,dislocation , or mobility. Palpation and percussion. Vitality testing : not routine & not reliable

3.2.2. Extraoral Soft tissue: wound, bruises Facial skeleton : palpated to detect any discontinuity TMJ: clicking, swelling Mandibular movement: pain stiffness, limitation in movement and opening

3.3. radiographs

3.3.1. To detect: Root fracture, alveolar bone fracture Radiolucencies, resorption Degree of displacement Extent of root development, size of the pulp chamber, unerupted teeth Baseline data documentation

4. complications

4.1. Reversible pulpits

4.2. Infection in periodontal ligament

4.3. Irreversible pulpitis

4.4. Pulp necrosis

4.5. Pulpal obliteration

4.6. Inf lammatory resorption

4.7. Ankylosis

4.8. Coronal discolouration

4.9. Injuries to developing permanent dentition

5. Classification

5.1. Teeth fracture

5.1.1. Crown Infraction crack of the enamel without loss of tooth structure. Crown fracture without pulp exposure Enamel cracks : Small Enamel fracture with sharp edge Large enamel fracture & dentin exposed Crown fracture with pulp exposure Primary teeth Permanent teeth

5.1.2. Crown & root Treatment Permanent teeth Primary teeth

5.1.3. Root . Treatment A mobile coronal fragment attached to the gingiva.

5.2. Displacement of teeth & injury to supporting tissue

5.2.1. Concussion . Treatment injury to the tooth-supporting structures without abnormal loosening or displacement of the tooth.

5.2.2. Subluxation . Treatment injury to tooth-supporting structures with ab-normal loosening but without tooth displacement.

5.2.3. Intrusion . Treatment Apical displacement of tooth into the alveolar bone.

5.2.4. Extrusion . Treatment partial displacement of the tooth axially from the socket; partial avulsion. PDL usually is torn.

5.2.5. Avulsion . Treatment complete displacement of tooth out of socket. PDL is severed and fracture of the alveolus may occur.

6. Treatment

6.1. Splinting

6.1.1. Indications Anavulsed tooth A displaced tooth An extruded tooth A root fractured tooth mobiletooth

6.1.2. Ideal properties Aesthetically acceptable tabilize the traumatized teeth No need for laboratory procedures simple Cause no damage
