A retrospective classification of tooth injuries using a new scoring system

Area of Science:

• Dentistry
• Oral Surgery
• Traumatology

Background:

• Current World Health Organization (WHO) classification for dental trauma lacks precision, categorizing injuries solely by the primary damage.
• A need exists for a more comprehensive diagnostic tool to assess the severity and predict the outcome of dental injuries.

Purpose of the Study:

• To introduce and evaluate a novel scoring system for diagnosing dental trauma.
• To compare the diagnostic capabilities of the new system with the existing WHO classification.
• To assess the prognostic value of the new scoring system in relation to treatment outcomes.

Main Methods:

• A retrospective study involving 100 traumatized teeth.
• Classification of injuries using both the WHO system and the new scoring system at the time of the accident.
• Clinical and radiological examinations, along with re-evaluation using the new scoring system during follow-up.

Main Results:

• The new scoring system demonstrated a more detailed categorization of dental trauma compared to the WHO classification, revealing score variations within single WHO injury types.
• Injuries like avulsion, intrusion, and root fractures (score < 30) presented the most unfavorable initial findings, while concussion and first-degree crown fractures (score > 70) showed the most favorable.
• A strong correlation was found between initial accident evaluations and follow-up assessments (P < 0.001).
• A score of 57 or higher at the time of the accident generally ensured successful therapy (P < 0.001).

Conclusions:

• The new scoring system provides a more complete diagnosis of dental trauma.
• The system offers valuable prognostic information, aiding in treatment planning and outcome prediction.
• This advanced system enhances the assessment of dental injuries beyond the limitations of the current WHO classification.
