What's the difference between osteodentine and pulp?
Osteodentine
Definition:
(n.) A hard substance, somewhat like bone, which is sometimes deposited within the pulp cavity of teeth.
Example Sentences:

(20) It therefore appears that osteodentin formation, as observed in the rat incisor pulp after adriamycin administration, is the result of an abnormal differentiation of pulp mesenchymal cells.
Pulp
Definition:
(n.) A moist, slightly cohering mass, consisting of soft, undissolved animal or vegetable matter.
(n.) A tissue or part resembling pulp; especially, the soft, highly vascular and sensitive tissue which fills the central cavity, called the pulp cavity, of teeth.
(n.) The soft, succulent part of fruit; as, the pulp of a grape.
(n.) The exterior part of a coffee berry.
(n.) The material of which paper is made when ground up and suspended in water.
(v. t.) To reduce to pulp.
(v. t.) To deprive of the pulp, or integument.
Example Sentences:
(1) The only sign of life was excavators loading trees on to barges to take to pulp mills.
(2) It is suggested that the reduction in the amount of white pulp present could explain at least in part the reduced ability of splenotic tissue to deal with infection.
(3) Some pulp irritation can occur if deep restorations are not placed over a protective film.
(4) Blood flow changes in the dental pulp of lower canine teeth of mature cats and incisors of mature rats were investigated with simultaneous laser Doppler flowmetry and local 125I-clearance (wash-out) during electrical sympathetic stimulation, efferent stimulation of n. alveolaris inferior (IAN) (cats) and i.a.
(5) The tooth also gave a positive response to pulp-testing procedures, even though no new tissue could be demonstrated histologically.
(6) We present our results with 8 free transfers of the toe pulp and demonstrate the successful restoration of a well-padded and sensitive fingertip.
(7) SP injection into the dental pulp and lip induced dye leakage.
(8) The root canal anatomy of 149 mandibular second molars was studied using a technique in which the pulp was removed, the canal space filled with black ink and the roots demineralized and made transparent.
(9) Surgical sympathectomy significantly reduced the NA content in the pulp by 76%.
(10) Monkey pulps were homogenized in a Triton tris solution.
(11) The fate, proliferation, and developmental potentialities of cell suspensions made from white pulp containing large germinal centers have been studied in the mouse by transfer of cells labeled with thymidine-(3)H to lethally irradiated, syngeneic recipients.
(12) While exposure of root surface dentin alone (negative control) produced no alterations, grinding the surface (positive control) caused noticeable changes in dentin, odontoblasts, and pulp.
(13) Control procedures were employed to assure that the electrical stimuli reached only tooth pulp fibers but no extrapulpal sensory fibers.
(14) The red pulp was characterized by increased densities of cells in pulp cords demonstrating metalophilia, hydrolytic enzyme activity, PAS positivity and hemosiderin.
(15) He reminds also of the possibility of the danger of iatrogenic damage for the dental pulp.
(16) Surprisingly, SP and CGRP caused weak albumin leakage in the pulp, while the opposite is true in high compliance tissues, such as muscles, suggesting that the vessels in a low compliance environment, such as the pulp, may not be as permeable in response to selected mediators.
