9.dilaceration

1. Dilaceration

2. Aetiology Trauma – mechanical trauma to calcified portion of partially formed tooth results in the displacement of calcified portion in dilaceration . The portion formed after accident is in different direction causing the dilaceration . Development defect – may be form as the developmental anomaly

3. Clinical features Most commonly found in maxillary incisors curve or bending occurs anywhere along the length of root, sometimes at cervical portion or midway along the root or even just at the apex of the root Sometimes, angles are so acute that the tooth does not erupt. If the defect is in the Crown of an erupted tooth, the angular distortion will be recognised

4. Radiographic features There may be inappropriate resorption of deciduous tooth which will delay the eruption of permanent teeth If the root bends mesially or distally conditions will clearly appear on radiograph

5. Diagnosis Clinical diagnosis is not possible Radiological diagnosis will show curved root

6. Management Difficulty at the time of extraction dilacerated Crown has to be restored improve aesthetic and function and to preclude dental caries and periodontal disease
