Symmetrical pulp obliteration in mandibular first molars.
Pulp obliteration is an extremely rare morphological type of pulp calcification, with calcified material completely occupying the pulp chamber and root canal spaces. The etiology of pulp obliteration may be trauma or systemic diseases such as secondary hyperparathyroidism. Pulp obliteration may also be seen in dental anomalies such as dentinogenesis imperfecta and dentinal dysplasia. In cases of pulp obliteration with periapical disease, the preferred treatment is surgery, while calcified canals without symptoms or periapical lesions are best left untreated.
