The use of beta-tricalcium phosphate, white MTA, white Portland cement and calcium hydroxide for direct pulp capping of primary pig teeth.

AIM The purpose of this study was to evaluate and compare the response of the pulp of primary pig teeth after capping with beta-tricalcium phosphate (ss-TCP), white mineral trioxide aggregate (WMTA), white Portland cement (WPC) and calcium hydroxide [Ca(OH)(2)]. MATERIAL AND METHODS Forty teeth of two 3-month old pigs were capped with these materials. Three weeks later, the animals were killed and the specimens were prepared for histological examination and evaluation of inflammatory cell response, tissue disorganization, hard tissue formation and bacteria presence was performed. The data collected from the histological examinations were statistically analyzed using Kruskal-Wallis and Dunn multiple comparison tests. RESULTS There was no significant difference between ss-TCP, WMTA, WPC and CH in terms of primary pulp response, hard tissue formation and normal pulp tissue preservation. CONCLUSION Beta-tricalcium phosphate, WMTA and WPC in primary pig teeth are as effective as Ca(OH)(2) in primary pig teeth capping.

Beta-tricalcium phosphate, white mineral trioxide aggregate, white Portland cement, ferric sulfate, and formocresol used as pulpotomy agents in primary pig teeth

OBJECTIVE The purpose of this study was to evaluate and compare the effects of formocresol (FC), ferric sulfate (FS), white mineral trioxide aggregate (WMTA), white Portland cement (WPC), and beta-tricalcium phosphate (beta-TCP) on pulpotomized primary teeth of pigs. STUDY DESIGN Fifty teeth of three 3-month old pigs were pulpotomized with these materials. Three weeks later, the animals were euthanized and the specimens were prepared for histological examination. RESULTS There was no significant difference between beta-TCP, WMTA, and WPC in terms of primary pulp response, hard tissue formation, and normal pulp tissue preservation. But, both FS and FC irritated the pulp tissue, provoking a more inflammatory pulp response than beta-TCP, WMTA, and WPC. CONCLUSION Beta-TCP, WMTA, and WPC are histologically more effective pulpotomy agents than formocresol and ferric sulfate in primary pig teeth.
