“…Since other studies have revealed that these factors may have an influence on different other hard tissue forming processes in the pulp space [1-3, 17, 18, 20, 23-25], it cannot be excluded that they may also have an influence on the narrowing of the pulp space analyzed in the present study. The most common reason for radicular pulp canal obliteration, which is a traumatic dental injury, was attempted to exclude in the present study by non-inclusion of incisor teeth, which are the most frequently affected teeth in dental traumata [4,6,31,32].…”

Narrowing of the radicular pulp space in coronally restored teeth

OBJECTIVES Narrowed radicular pulp spaces are frequently observed in teeth wearing extended restorations. The present study investigates whether the narrowing of particularly the radicular pulp space can be attributed to coronal restorations. MATERIALS AND METHODS The study is based on an anonymized copy of the cone-beam computed tomography (CBCT) database from the Center of Dental Medicine of the University of Zurich. One hundred CBCT scans were selected out of 7317 data sets to match either a crowned (group A; n = 50) or a filled tooth (group B; n = 50) with a contralateral healthy, unrestored, and caries-free control tooth at the same position, respectively. Cross-sectional images were adjusted in the coronal, middle, and apical root third of each subjected tooth. Screenshots were taken in that position and analyzed. The area occupied by the pulp space was determined as percentage area of the whole root diameter on each cross section. The resulting values were compared between restored and control teeth. RESULTS In both groups (crowned and filled teeth) and in all the three root thirds, the radicular pulp space was significantly narrower in the restored teeth compared to the control teeth. The strongest narrowing effect was observed in the coronal root third and it decreased towards the apical root third (both groups). CONCLUSIONS Teeth with coronal restorations show within the limitations of the present study a significant narrowing of their radicular pulp space. CLINICAL RELEVANCE The asserted narrowing could have a complicating effect if root canal treatment becomes necessary in those teeth.

“…They reasoned that the pulp tissue involved should be regarded as a potential focus of infection and should be removed 5 . Holcomb and Gregory followed 34 patients with 41 teeth with PCO over a 4 year period and found that 7.3% developed a periapical rarefaction 6 . In a 3.4 year follow-up study by Andreasen, 7% of the patients developed pulpal necrosis following PCO 7 .…”

“…Calcification, per se, does not necessarily imply that progressive inflammation of the pulp or pulp necrosis will occur. In fact, pulp necrosis is found in less than 7% of traumatically induced calcified pulps (94). Lastly, the mineral content of the tertiary dentin represents more than just calcium hence the term pulp canal mineralization would be a more accurate term.…”
