PULP OBLITERATION - A HISTOLOGICAL STUDY

Pulp obliteration is a very rare occurrence that is most frequently ca used by trauma. A 58-yr-old female patient had a generalized pulp obli teration that involved all maxillary and mandibular teeth. One tooth w as extracted due to an extensive carious lesion and it was processed b y a cutting-grinding technique. It was possible to observe the complet e obliteration of the pulp chamber, which was filled in part by repara tive dentin and in part by a calcified tissue with a concentric layers structure with no tubular pattern. The root canals were almost comple tely obliterated by an amorphous calcified material.
