A similar pattern was observed in mature teeth where there was a significantly greater MVD in the coronal region than in the middle region (P=0.04), and regression analysis showed that there was a significantly greater proportion of blood vessels in the coronal pulp
(1.32 times) than in the middle region (P=0.03).
In 2008 Drusini argued that age has greater influence on secondary deposition than attrition or irritation as more secondary dentin is normally deposited on the floor of the coronal pulp
cavity than on the roof.

After amputation of the inflamed coronal pulp
(pulpotomy), recovery of the non-inflamed radicular pulp can develop along one of three lines:
A reduction in the size of the coronal pulp
chamber is initially observed, and is followed by the gradual narrowing of the entire root canal, not rarely leading to complete obliteration, although a narrow root canal space always persists histologically.
The treatment for the pulp polyp was cervical pulpotomy because following coronal pulp
amputation, the bleeding appeared normal in color, no excessive bleeding was present, and good hemostasis was achieved .
The calcified tissue occluding the coronal pulp
chamber appeared to represent a reparative response to a prior process of resorption since the normal coronal dentine have scalloped margins in contact with the abnormal tissue.
Although meticulous pre-operative clinical and radiographic assessment is mandatory, accurate pulp diagnosis is challenging because clinicians rely on clinical assessment of bleeding to evaluate radicular pulp health following coronal pulp
The coronal pulp
was then carefully removed and cut into 10 [micro]m longitudinal sections.
Formocresol and Calcium hydroxide pulpotomy was performed after amputation and proper hemostasis of the coronal pulp
chamber and the selected patients were divided into two groups.
It implies removing infected and inflamed coronal pulp
tissue at the level of the entrance of the root canals and has been used in exposed carious or traumatized teeth with incomplete root formation.
After removal of the coronal pulp
two canals were localized (one buccal and one palatal) periapical radiograph was taken to determine the working length (figure 1).
