Root fractures in permanent anterior teeth with incomplete root formation

Area of Science:

• Dentistry
• Endodontics
• Oral Surgery

Background:

• Root fractures in permanent teeth can be challenging to diagnose, especially those with incomplete root formation.
• Initial radiographic assessment may miss subtle fractures, necessitating careful clinical evaluation.

Purpose of the Study:

• To evaluate the long-term outcomes of treating permanent teeth with root fractures and incomplete root formation.
• To assess the potential for normal root development and pulp vitality following fracture management.

Main Methods:

• A follow-up study of seven teeth with incomplete root formation and root fractures.
• Initial diagnosis via radiographs and clinical examination, followed by reduction and fixation.
• Long-term observation period ranging from 1.5 to 19 years.

Main Results:

• All seven teeth demonstrated retained pulp vitality and repair at the fracture site.
• Approximately normal root development, including apical foramen closure, was observed in all cases.
• Two teeth experienced re-fracture but ultimately achieved successful long-term results.

Conclusions:

• Root fractures in teeth with incomplete root formation can be successfully managed with reduction and fixation.
• Normal root development and pulp vitality can be achieved and maintained long-term, even after re-fracture.
