Definition: Incomplete crack or fracture within the enamel without loss of structure.
Clinical Findings:
- Visible as fine cracks on the enamel surface, often seen under transillumination.
- No sensitivity or tenderness.
Radiograph:
- Typically normal; infractions are not radiographically visible.
Treatment:
- No treatment required if there is no associated discomfort.
- Apply resin to seal the cracks if aesthetics or sensitivity is a concern.
- Monitor for any progression or development of sensitivity.
Follow-Up:
- No routine follow-up needed unless symptomatic or crack worsens.
- Reassess if patient reports pain or sensitivity.
Based on IADT guidelines. (Dent Traumatol 2012;28:2-12)

Intraoral Findings
Soft Tissues:
- Lacerations: No lacerations noted on the surrounding soft tissues.
- Bleeding: No bleeding observed.
- Swelling: No significant swelling detected.
Tooth Findings:
- Tooth #8:
- Fracture: Fine cracks (infractions) visible within the enamel, detected under transillumination.
- Mobility: No abnormal mobility detected.
- Displacement: The tooth is in its correct anatomical position.
- Percussion: No tenderness noted upon percussion.
- Sensitivity Testing (cold, electric pulp test): Normal response, indicating pulp vitality.
Radiograph
- Periapical Radiograph:
- No signs of root or apical involvement.
- No visible fracture lines detected radiographically.
- Periodontal ligament space appeared intact.
Plan
Immediate Management:
- Observation and Monitoring:
- No immediate treatment required as the infractions were superficial and asymptomatic.
- Advised monitoring for any signs of sensitivity or discoloration over time.
- Optional Treatment (If Aesthetic Concern):
- Recommended application of a resin sealant over the infraction lines to prevent staining or bacterial infiltration, if requested by the patient.
- Oral Hygiene:
- Advised meticulous oral hygiene to prevent plaque accumulation that could exacerbate the infraction lines.
Follow-Up Schedule:
- 6 Months: Clinical and radiographic evaluation to confirm no progression or secondary complications.
- 1 Year: Long-term follow-up to ensure the tooth remains asymptomatic and structurally stable.
Warning About Risks Associated with Dental Trauma
Although enamel infractions are typically superficial, there is a slight risk of cracks deepening or causing sensitivity over time. Regular follow-ups and prompt reporting of symptoms such as discoloration, sensitivity, or pain are essential for monitoring and management.
