RESUMO

The aim of this study was to compare the clinical and radiographic effectiveness of formocresol and Portland cement as pulp dressing agents in carious primary teeth. Sixty eight primary mandibular molars of 52 children between 5 and 9 years old were criteriously selected. The teeth were randomly assigned to formocresol or Portland cement groups, and treated by a conventional pulpotomy technique. After coronal pulp removal and hemostasis, in the formocresol group (34 teeth), a cotton pellet, soaked in the solution, was placed for 5 minutes over the pulp stumps and then the pulp chamber was filled with zinc oxide-eugenol paste. In the other group (34 teeth), an 1 mm-thick paste of Portland cement was placed over the pulp stumps. All the teeth were restored with reinforced zinc oxide-eugenol base and resin modified glass ionomer cement. Clinical and radiographic evaluations were recorded at 3, 6 and 12-month follow-up. The sixty eight teeth were available for 3 and 6-month follow-up; however, at 12-month follow-up appointment, 6 teeth could not be assessed (4 teeth exfoliated and 2 children had their address changed). No signs of clinical failure were observed at all follow-up appointments in both group. The radiographic evaluation revealed only one case of internal resorption detected at 3-month follow-up in the formocresol group. Dentine bridge was detected in 2 teeth in the Portland cement group. Statistically significant difference was only observed between both groups when assessing tooth crown discoloration and pulp canal obliteration, which were observed in all teeth treated with Portland cement at all follow-up appointments. Portland cement may serve as an effective substitute of formocresol in primary molar pulpotomies. Although our results are very encouraging, further studies and longer follow-up assessment are needed in order to determine the safety clinical indication of Portland cement.
