Thus, 58 patients with 86 eligible carious lesions remained in the study, in 18 of which close approximation of a pulp horn
was inferred by the altered dentine colour over it (Table 2).
There is well defined pulp chamber in the trunk of the tooth with pulp horns
elongated under each cusp but more profound under the buccal cusp.
In the pulp horn
region, both hypomineralised subgroups had significantly greater vascular expression of TRPV1 than sound samples (P <0.05, ANOVA).
Most likely, the prominent pulp horns
that project under the cusps of the taurodont tooth cause the enlargement in spite of the normal size of the dentine.
Otherwise, both DTS and DT also had difficulty recalling the position of pulp canals in such teeth, although the DS were more knowledgeable of the exposure of the mesio-buccal pulp horn
of primary molar teeth during preparation compared with the qualified dentists and therapists.
For both tooth types, VEGFR2+ cells were seen in the CRZ, particularly in the region of the pulp horns
, but there was a significantly greater expression in the coronal region of immature teeth than that of mature teeth (P=0.001).
The pulp horns
and root canals also reduce in volume.
