Transient red discoloration: report of case

Area of Science:

• Pediatric Dentistry
• Dental Traumatology
• Tooth Discoloration

Background:

• Primary teeth are susceptible to trauma, which can lead to various complications.
• Red discoloration in primary teeth following injury is a recognized, though not fully understood, phenomenon.

Observation:

• A case study documented the distinct evolutions of red discoloration in primary maxillary central incisors of the same patient.
• The right central incisor's red discoloration resolved completely.
• The left central incisor's discoloration faded but persisted until the tooth's natural exfoliation.

Findings:

• The observed differences in discoloration resolution support the concept of a transient type of post-traumatic tooth discoloration.
• The study proposes the resorption of intrapulpal bleeding, occurring after trauma, as a potential mechanism for this transient discoloration in primary teeth.

Implications:

• This case provides clinical evidence for transient red tooth discoloration following dental trauma.
• Understanding the pathogenesis of post-traumatic discoloration aids in diagnosis and management of injuries in primary dentition.
• Further research into intrapulpal bleeding resorption could refine treatment strategies for traumatized primary teeth.
