What clinical sign indicates pulp canal obliteration (PCO) following dental trauma?
Answer: Yellow-brown crown discoloration with radiographic narrowing of the canal
Pulp canal obliteration causes yellow-brown crown discoloration and radiographic canal narrowing due to excessive tertiary dentin deposition.
When should root canal treatment be initiated in a traumatized tooth diagnosed with pulp necrosis?
Answer: Promptly once pulp necrosis is diagnosed clinically and radiographically
Root canal treatment should begin promptly once pulp necrosis is diagnosed to prevent inflammatory root resorption and periradicular pathology.
What is the most common long-term complication in replanted avulsed permanent teeth?
Answer: Ankylosis with progressive replacement resorption
Ankylosis with progressive replacement resorption is the most common long-term complication, especially when PDL cell viability was compromised during the avulsion period.
What radiographic sign is pathognomonic for replacement resorption (ankylosis) after tooth replantation?
Answer: Loss of the PDL space with continuous bone trabeculae crossing the root surface
Loss of the normal PDL space with bone trabeculae running continuously across the root surface is pathognomonic for ankylosis (replacement resorption).
Which intracanal medicament is recommended to inhibit inflammatory root resorption following traumatic dental injuries?
Answer: Calcium hydroxide paste
Calcium hydroxide paste creates a high-pH environment that inhibits osteoclastic activity, thereby suppressing inflammatory root resorption.
According to IADT guidelines, what is the recommended minimum follow-up period for a lateral luxation injury?
Answer: Clinical and radiographic review at regular intervals for up to 5 years
IADT guidelines recommend regular clinical and radiographic follow-up at multiple intervals over 5 years to detect late complications such as pulp necrosis, resorption, or ankylosis.
