“…The globules are comparable in location and, apparently, in structure with the denticles or "pulp stones" in human teeth (cf. Johnson and Bevelander 1956). Whereas in man these are regarded as pathological and are associated with old age, they make up a major part of each normal tooth of the walrus from the first year.…”

“…16 Stones may exist freely within the pulp tissue or be attached to or embedded in dentine. 17 More often than not, the existence of pulp stones may lead to narrowing or obstruction of the access to the apical point in the root canal; this is one of the most important factors leading to the failure of root canal therapy and loss of the teeth. We have discovered the close relationship between CNPs and dental pulp calcification in a former investigation, 18 which indicated that CNPs might possibly play an important role in the formation of dental pulp stones.…”

Calcifying nanoparticles (CNPs, previously called nanobacteria) are self-propagating, cultivable macromolecular complexes. Their extraordinary characteristic is that they can aggregate carbonate apatite on their envelope from soluble calcium and phosphorus at physiologic concentrations and display cytotoxic effects on murine and human fibroblast cell lines. The question arises whether CNPs contribute to the degeneration of pulp tissue and thus result in clinically significant human dental pulp stones as nidies. This study evaluates CNPs’ effects upon human dental pulp cells (HDPCs, the host cells in pulp tissue). We observed the ultrastructural variation of HDPCs attacked by CNPs. The spatial relationship of HDPCs and CNPs after coculture was also identified by immunofluroscence staining. Furthermore, it was verified by MTT viability assay that CNPs isolated from dental pulp stones exerted cytotoxic effect on HDPCs. Therefore, it could be concluded that the existence of CNPs might interfere with the normal physiologic function of the cells, and that might lead to dental pulp calcification. Elucidation of the cytotoxic characteristics of CNPs may offer a new perspective for understanding the etiology of human dental pulp stones.

“…Embedded stones are found frequently in the apical portion of the root and the presence of odontoblasts and calcified tissue resembling dentin can occur on peripheral aspect of these stones. 1 Adherent pulp stones are never fully enclosed by dentin and are less attached to dentin than embedded pulp stones. Adherent and embedded pulp stones can interfere with root canal treatment, if they cause significant occlusion of canals or are located at a curve.…”

Pulp Stone—An Endodontic Challenge: Successful Retrieval of Exceptionally Long Pulp Stones measuring 14 and 9.5 mm from the Palatal Roots of Maxillary Molars

Pulp stones are nodular, calcified masses commonly appearing in the coronal pulp and occasionally extending in radicular pulp. Retrieval of pulp stones remains a challenge for the endodontist as complete cleaning and shaping of root canal system is the bases for successful endodontic therapy. The aim of this case report is to show the retrieval of long pulp stones measuring 14 and 9.5 mm by utilizing synergistic effect of ultrasonics and sodium hypochlorite from the palatal roots of maxillary molars. Such case has not been reported in the literature so far.
