This theory is based on the premise that the cementum and predentin
covering on dentin are essential elements in the resistance of the dental root to resorption.
Clefts of various sizes, interglobular dentin, focally-widened predentin zones, and decreased number of dentinal tubules are prominent features of the affected dentin.
30 The odontoblasts appear flattened, rimming the margin of the predentin.
The cervical portion has more predentin
than the incisal region.
However, the expression was intense in predentin and in the tissues in the resorption process.
The expression was weak in dentin, in predentin and in tissues in the process of resorption, in all the groups.
These results were in agreement with the literature, which reports an intense presence of biglycan in predentin dental germs of newborn rats (7) at 7 and 11 days of age.
Its expression was weak in dentin and predentin (Figure 1E).
Dentin deposits completely cease in severe vitamin C deficiencies, with hypercalcification of predentin
Dentin Sialophosphoprotein knockout mouse teeth display widened predentin
zone and develop n-defective dentin mineralization similar to human dentinogenesis imperfecta type II.
3) The tetracycline is incorporated into the enamel and dentine and the chelated molecule arrives at the mineralizing predentin
dentin junction via the terminal capillaries of pulp (patel et al 1998).
Instrumentation of root canal removes all necrotic debris, predentin
and any infected superficial dentin and shapes the canal to receive a root canal filling.
