Abstract |

Purpose: The aim of this study was to use clinical, radiographic, and histologic examinations
to compare the relative success of gray mineral trioxide aggregate (MTA), white
MTA, and formocresol as pulp dressings in pulpotomized primary teeth.
Methods: Twenty-four childten, each with at least 3 primary molars requiring pulpotomy,
were selected for this study's clinical and radiographic portion. An additional 15
carious primary teeth planned for serial extraction were selected for this study's histologic
portion. All selected teeth were evenly divided into 3 test groups and treated with
pulpotomies. Gray MTA was used as the pulp dressing for one third of the teeth, white
MTA was the dressing for one third, and the remaining one third were treated with
formocresol. The treated teeth selected for the clinical and radiographic evaluations were
monitored periodically for 12 months. The treated teeth selected for histologic study
were monitored periodically and extracted 6 months postoperatively.
Results: Four children with 12 pulpotomized teeth failed to return for any follow-up
evaluations in the clinical and radiographic study. Of the remaining 60 teeth in 20 patients,
1 tooth (gray MTA) exfoliated normally and 6 teeth (4 white MTA and 2
formocresol) failed due to abscesses. The remaining 53 teeth appeared to be clinically
and radiographically successful 12 months postoperatively. Pulp canal obliteration was
a radiographic finding in 11 teeth treated with gray MTA and 1 tooth treated with white
MTA. In the histologic study, both types of MTA successfully induced thick dentin bridge
formation at the amputation sites, while formocresol induced thin, poorly calcified dentin.
Teeth treated with gray MTA demonstrated pulp architecture nearest to normal pulp
by preserving the odontoblastic layer and the delicate fibrocellular matrix, yet few inflammatory
cells or isolated calcified bodies were seen. Teeth treated with white MTA
showed a denser fibrotic pattern, with more isolated calcifications in the pulp tissue along
with secondary dentin formation.
Conclusion: Gray MTA appears to be superior to white MT A and to formocresol as a
pulp dressing for pulpotomized primary teeth. (Pediatr Dent. 2004;26:XXX-XXX)
