Preventive measures have helped to minimize the occurrence of
dental caries. However, premature loss of primary teeth on account of
dental caries still remains a common problem among children. The
pulpotomy technique has been the choice for treating vital primary and young permanent teeth with carious, mechanical and traumatic pulp exposures. The ideal
pulpotomy medicament should be bioinductive or at least biocompatible, bactericidal and harmless to the pulp and surrounding structures. It should also promote healing of the radicular pulp and prevent bacterial microleakage with the least interference in the physiological process of
root resorption. Since the best criteria for judging the effectiveness of a medicament when used for vital pulp
therapy is the response that it produces in the pulp. The purpose of the present study was to evaluate and compare the response of human pulp tissue to recently developed Indian material, Sree
Chitra-
Calcium Phosphate Cement (
Chitra-
CPC) and
formocresol, used as
pulpotomy agent in deciduous teeth.
Chitra-
CPC has been compared with
formocresol, taking into account that
formocresol is still considered the gold standard in primary tooth
pulpotomy. The study was conducted among 10 children in the age group of 8 to 12 years focusing on 20 noncarious primary canines indicated for
serial extraction. Each patient received two different
pulpotomy procedures-one in each of the primary canines using
formocresol and the other with
Chitra-
CPC as
pulpotomy agents. After 70 days, the teeth were extracted and subjected to histological examination. The results did not reveal statistically significant difference between the two groups. But
Chitra-
CPC gave more favorable results, in respect of pulpal
inflammation, dentin bridge formation, quality of dentin bridge and connective tissue in dentin bridge. How to cite this article: Ratnakumari N, Thomas B. A Histopathological Comparison of Pulpal Response to
