Histology
No irregularities in the dentin below invagination
Strains of vital tissue or fine canals that communicates with the pulp could be found
Enamel lining irregularly structured
External and internal enamel have different structures

Management
Preventative treatment - e.g. oral hygiene instructions, fissure sealant
Intentional replantation
Root canal treatment with mineral trioxde aggregate
Periapical surgery with retrograde filling
Extraction

The tumor can also compress the recurrent laryngeal nerve and from this a hoarse voice and "bovine" (non-explosive) cough may occur.In superior vena cava syndrome, obstruction of the superior vena cava by a tumor (mass effect) causes facial swelling cyanosis and dilatation of the veins of the head and neck.A Pancoast tumor is an apical tumor that is typically found in conjunction with a history of smoking tobacco. The clinical signs and symptoms may be mistaken for neurovascular compromise at the level of the superior thoracic aperture. The patients smoking history, rapid onset of clinical signs and symptoms, and pleuritic pain can suggest an apical tumor. A Pancoast tumor can give rise to both Pancoast syndrome and Horners syndrome. When the brachial plexus roots are involved, it will produce Pancoast syndrome; involvement of sympathetic fibers as they exit the cord at T1 and ascend to the superior cervical ganglion will produce Horners syndrome. Diagnosis
Diagnosis of Pancoast tumor is usually made after evaluating clinical symptoms and imaging. Chest X-ray is a good screening test even though a CT scan of the chest can provide a better resolution and extent to which internal organs are being compressed. Treatment
The treatment of a Pancoast lung cancer may differ from that of other types of non-small-cell lung cancer. Its position and close proximity to vital structures (such as nerves and the spine) may make surgical intervention difficult. As a result, and depending on the stage of the cancer, treatment may involve radiation therapy and chemotherapy given prior to surgery (neoadjuvant treatment).
