INBDE (Integrated National Board Dental Examination) Practice Exam

Treatment for complicated crown fracture in a vital primary tooth is:

1. Extraction

2. Reposition, splint 1-2 weeks

3. No treatment

4. Pulpotomy

The correct answer is: Pulpotomy

Treatment for a complicated crown fracture in a vital primary tooth involves preserving the tooth structure and maintaining its function. In this case, performing a pulpotomy is the most appropriate treatment option. A pulpotomy involves the removal of the infected portion of the dental pulp, while preserving the remaining healthy pulp tissue to maintain the vitality of the tooth. This treatment helps to alleviate pain, prevent further infection, and allow for proper healing and restoration of the tooth. Options A, B, and C are not the recommended treatments for a complicated crown fracture in a vital primary tooth. Extraction would involve removing the tooth, which is not typically the first choice for a primary tooth with a complicated crown fracture. Repositioning and splinting for 1-2 weeks may be applicable for other types of dental injuries, but it is not the primary treatment for a complicated crown fracture. Lastly, leaving the tooth untreated (No treatment) can lead to pain, infection, and further complications, so it is not the ideal approach in this scenario. Therefore, the most appropriate treatment for a complicated crown fracture in a vital primary tooth is a pulpotomy.
