Case Series: root healing with MTA after horizontal fracture

Area of Science:

• Dentistry
• Endodontics
• Dental Traumatology

Background:

• Root fractures in permanent teeth are uncommon and complex injuries.
• Most root fractures occur in the middle third of the root.

Observation:

• Three pediatric cases of horizontal mid-third root fractures in anterior teeth are presented.
• Clinical presentations included lip swelling, pain, mobility, and discoloration.

Findings:

• Mineral trioxide aggregate (MTA) was used as a fracture line plug in the coronal segment.
• All cases demonstrated excellent healing patterns at 36-month follow-up, with asymptomatic teeth.

Implications:

• MTA is a suitable material for definitive root filling in horizontal root fractures.
• MTA's biological and physical properties support its use in managing dental trauma.
