How to treat an intruded tooth with incomplete root formation?
The treatment for an intruded permanent tooth with incomplete root formation is to allow it to erupt spontaneously. If no movement is seen within a few weeks, orthodontic repositioning should begin. If the tooth is intruded 7 mm or more, the tooth can be repositioned surgically and stabilized by means of a flexible splint. Endodontic therapy is often required, however, and the tooth should be monitored closely while a decision on endodontic therapy is pending. 5
What is a pulpotomy in teeth?
Pulpotomy is performed in teeth in which it is assumed that healthy pulp tissue, with a potential to produce a dentin bridge and complete the formation of the root, remains in the root canal. The technique for coronal pulpotomy in permanent teeth is similar to that for primary teeth, and the dressing material should maintain pulp vitality and function. Care should be taken to remove the blood clot before placement of a calcium hydroxide paste over the pulp stumps because its presence may compromise the treatment outcome. It has been demonstrated that leaving the blood clot may result in the formation of dystrophic calcifications and internal resorption. The blood clot may also interfere with dentin bridge formation and serve as a substrate for bacteria if a leaky restoration is present.112

What is the root of a tooth?
The root of the tooth is embedded in the skull. The exposed part of the tooth is covered by enamel and is called the crown. The tooth itself is composed of dentin, a bonelike structure that surrounds the pulp cavity and underlies the enamel. The tooth roots are covered by a thin layer of bonelike tissue called the cementum, which cannot be distinguished, grossly or radiographically, from the underlying dentin. The pulp cavity, or hollow center of the tooth, contains nerves, arteries, veins, lymphatics, and connective tissue. At the apex of each root is the apical foramen, through which nerves and vessels enter the pulp cavity.
