### Examination

**Dr Jilen Patel**

A rational examination procedure is essential in order to establish a complete and correct diagnosis of all soft and hard tissue injuries (Andreasen and Andreasen 1985, Bakland and Andreasen 1996, Andreasen et al. 2007).

*   **Clean the face and the oral cavity with water or saline**. If there are soft tissue wounds, a mild detergent should be used. This cleaning will make the patient feel more comfortable and facilitate extraoral and oral examination.
*   **Make a short medical and dental history**. The medical history should reveal possible allergies, blood disorders and other information that may influence treatment. The dental history should indicate previous dental traumas, information which may explain radiographic findings such as pulp canal obliteration or apical pathology.

### Questions relating to the injury

*   **Where did the injury occur?** This information may have legal implication for the patient and may on occasion indicate the possibility of contamination.
*   **How did the injury occur?** This may lead to identification of the impact zones, i.e. a chin injury is often combined with crown or crown-root fractures in premolar and molar regions.
*   **When did the injury occur?** This information may be essential in relation to many injury types. In relation to a tooth avulsion the extent of time and the extraoral storage condition becomes very decisive for later treatment.
*   **Was there a period of unconsciousness?** If so, for how long? Amnesia, nausea and vomiting are all signs of brain damage and require medical attention.
*   **Is there any disturbance in the bite?** An affirmative answer may indicate a luxation injury with displacement, an alveolar or jaw fracture or a fracture of the condylar region.
*   **Is there any reaction in the teeth to cold and/or heat exposure?** A positive finding indicates exposed dentin and/or pulp.

### Clinical examination

*   *Examine* the face, lips and oral muscles for soft tissue lesions.
*   *Palpate* the facial skeleton for signs of fractures.
*   *Inspect* the dental trauma region for fractures, abnormal tooth position, tooth mobility and abnormal response to percussion. Furthermore, registration of direction of displacement in case of luxation injuries. In case of fractures their relation to the gingival sulcus area is noted as well as possible pulp involvement.
*   *Pulp testing* (usually electrometric) completes the clinical examination.</text>
    <formatted_text>A rational examination procedure is essential to establish a complete and correct diagnosis of all soft and hard tissue injuries.

#### Initial Preparation and History

- **Clean the face and oral cavity**: Use water or saline. For soft tissue wounds, use a mild detergent to improve patient comfort and facilitate the examination.
- **Medical and Dental History**: Identify allergies, blood disorders, or previous dental traumas that may explain radiographic findings like pulp canal obliteration or apical pathology.

#### Diagnostic Questions

- **Where did the injury occur?** Relevant for legal implications and identifying potential contamination.
- **How did the injury occur?** Helps identify impact zones (e.g., a chin injury often correlates with premolar/molar fractures).
- **When did the injury occur?** Critical for treatment decisions, especially regarding extraoral storage time for avulsed teeth.
- **Was there unconsciousness?** Amnesia, nausea, and vomiting are signs of brain damage requiring medical attention.
- **Is there a bite disturbance?** May indicate luxation, displacement, alveolar/jaw fractures, or condylar fractures.
- **Is there sensitivity to temperature?** Positive findings indicate exposed dentin or pulp.

#### Clinical Assessment Steps

- **Soft Tissue**: Examine face, lips, and oral muscles for lesions.
- **Skeletal**: Palpate the facial skeleton for fractures.
- **Dental Region**: Inspect for fractures, abnormal positioning, mobility, and percussion response. Note displacement direction and relationship of fractures to the gingival sulcus or pulp.
- **Pulp Testing**: Complete the examination with electrometric pulp testing.</formatted_text>

## Examination

### Radiographic examination

* The completed clinical examination has now identified the trauma region and this site should now be examined with relevant radiographic techniques. Several clinical studies have shown that multiple radiographic procedures are needed to detect displacement of the tooth in its socket as well as presence of root fractures (Andreasen and Andreasen 1985, Andreasen and Andreasen 1988).

&amp;gt; It is essential to consider the radiographic film format used in order to achieve a high quality image of the traumatized tooth. A steep occlusal exposure (using a size 2 film (DF 58, EP 21)) of the traumatized anterior region gives an excellent view of most lateral luxations, apical and mid-root fractures and alveolar fractures.

The standard periapical bisecting angle exposure of each traumatized tooth (using a size 1 film (DF 56, EP 11)) provides information about cervical root fractures as well as other tooth displacements. Thus, a radiographic examination comprising one steep occlusal exposure and three periapical bisecting angle exposures of the traumatized region will provide sufficient information in determining the extent of trauma to an incisor region.</text>

#### Radiographic Techniques and Film Formats

- **Steep Occlusal Exposure**: Using a size 2 film (DF 58, EP 21). Provides an excellent view of lateral luxations, apical and mid-root fractures, and alveolar fractures.
- **Periapical Bisecting Angle Exposure**: Using a size 1 film (DF 56, EP 11) for each traumatized tooth. Provides information on cervical root fractures and other displacements.

#### Recommended Examination Protocol

A comprehensive examination of the incisor region should comprise:
1. One steep occlusal exposure.
2. Three periapical bisecting angle exposures.</formatted_text>

**Examination**

## Radiographic examination

The completed clinical examination has now identified the trauma region and this site should now be examined with relevant radiographic techniques. Several clinical studies have shown that multiple radiographic procedures are needed to detect displacement of the tooth in its socket as well as presence of root fractures (Andreasen and Andreasen 1985, Andreasen and Andreasen 1988).

A *steep occlusal exposure* (using a size 2 film DF 58, EP 21) of the traumatized anterior region gives an excellent view of most lateral luxations, apical and mid-root fractures and alveolar fractures. The standard periapical bisecting angle exposure of each traumatized tooth (using a size 1 film DF 56, EP 11)) provides information about cervical root fractures as well as other tooth displacements.

![](L8 Dental Trauma Primary Dentition_figures/img_8486d40ef0187e3a.webp)</text>
    <formatted_text>Clinical studies emphasize that multiple radiographic views are required to accurately identify displacement and root fractures.

#### Standard Imaging Views

- **Steep Occlusal Exposure (Size 2 film)**: Best for detecting lateral luxations, apical/mid-root fractures, and alveolar fractures.
- **Periapical Bisecting Angle Exposure (Size 1 film)**: Essential for identifying cervical root fractures and specific tooth displacements.

#### Summary of Protocol

To provide sufficient diagnostic information for the incisor region, the examination should include one steep occlusal exposure and three periapical bisecting angle exposures.</formatted_text>

## Treatment options

### 1. Conservative management
* soft diet, analgesia, ongoing review and monitoring

---

**Extrusive or *lateral* luxation:**
*   **Extrusion:** ~15-43% complication rate
*   **Lateral luxation:** ~20-40% complication rate
    *   *(Complications:** pulp necrosis, resorption, PCO, premature loss*)
*   *Most complications occur within the first 12 months (~96%)*
*   *More likely: in children &amp;gt;4 yrs old and concomitant crown fracture*

    <formatted_text>#### Extrusive and Lateral Luxation

- **Complication Rates**:
    - Extrusion: 15–43%
    - Lateral Luxation: 20–40%
- **Types of Complications**: Pulp necrosis, resorption, PCO, and premature tooth loss.
- **Prognostic Factors (Lauridsen et al. 2017)**:
    - 96% of complications occur within the first 12 months.
    - Higher risk in children over 4 years of age or when a concomitant crown fracture is present.</formatted_text>

## Treatment options

1. Conservative management  
   - soft diet, analgesia, ongoing review and monitoring  

**OR**

2. Extraction  
   - extent of injury  
   - occlusal interference  
   - pulpal exposure  
   - degloving injuries

*Andersson et al. 2012*</text>
    <formatted_text>#### Indications for Extraction vs. Conservative Care

Extraction is preferred over conservative management (soft diet/monitoring) when the following are present (Andersson et al. 2012):

- Severe extent of injury.
- Occlusal interference that prevents normal closing.
- Direct pulpal exposure.
- Degloving injuries.</formatted_text>

*   Crown fractures in the primary dentition
    *   **uncomplicated**
        *   conservative management and review
    *   **complicated**
        *   usually extraction
        *   can be referred to a paediatric dentist if the parents want to look at options to maintain the tooth

    <formatted_text>#### Management Protocols by Fracture Type

- **Uncomplicated Crown Fractures**:
    - Managed via conservative treatment and regular clinical review.
- **Complicated Crown Fractures**:
    - Extraction is the standard treatment.
    - Referral to a paediatric dentist may be considered if parents wish to explore specialized options to maintain the tooth.</formatted_text>
