  1. Intercommunication between all pulp horns was observed up to 9 years post eruption. Partially segmented pulp systems (PS) were seen in teeth ≥ 2.5 years post eruption. Configurations of PS varied – solitary, medium sized or large separate pulp compartments were combined. Four pulp compartments (MS) were found in teeth ≥8 years post eruption. In all teeth >20 years rudimentary dental cavities were observed.
