Crown fracture of the mandibular second primary molars in a 4-year-old child.

Dental traumas are highly prevalent lesions in primary teeth, but crown root fractures are rare. Mostly anterior tooth segment is more commonly involved. Posterior crown root fractures are very rare. A 4-year-old girl reported to our paediatric dentistry department with a 10-day history of severe pain and discomfort in both right and left posterior teeth region. The child was suffering from severe and continuous pain and was unable to chew food. After an examination a fracture was noticed in intraoral periapical radiograph and treatment plan was decided to preserve the affected teeth.
