Estudo clínico e radiográfco do formocresol de Buckley a 1/5 e do cimento Portland utilizados para pulpotomias em dentes decíduos humanos / Clinical and radiographic study on 1/5 dilution of Buckley?s formocresol and Portland cement used for pulpotomies of human primary teeth

O objetivo deste estudo foi comparar a eficácia clínica e radiográfca do formocresol de Buckley diluído a 1/5 e do cimento Portland como agentes capeadores pulpares em dentes decíduos humanos acometidos por cárie extensa, tratados pela técnica convencional de pulpotomia. Sessenta e oito primeiros molares inferiores em 52 crianças com idades entre 5 e 9 anos foram criteriosamente selecionados. De forma randômica, formaram-se dois grupos de 34 molares, cada qual sendo tratado com um dos agentes capeadores a serem comparados. Após a realização das pulpotomias, avaliações clínicas e radiográficas foram realizadas nos períodos de 3, 6 e 12 meses do pós-operatório. Nenhum sinal de falha clínica foi observado, para ambos os grupos, em todos os períodos avaliados. Diferença estatisticamente signifcativa entre os grupos foi observada apenas quando avaliada a coloração da coroa dentária e a obliteração do canal radicular, visto que todos os dentes tratados com o cimento Portland apresentaram discreta coloração acinzentada e estenose radicular. O cimento Portland foi tão efetivo quanto o formocresol como capeador pulpar em pulpotomias de dentes decíduos. Embora os resultados sejam encorajadores, estudos futuros e com acompanhamentos a longo prazo são necessários para se determinar a indicação clínica segura do cimento Portland.

This study aimed at comparing the clinical and radiographic effectiveness of 1:5 dilution of Buckley?s formocresol and Portland cement as pulp dressing agents in carious primary teeth treated by conventional pulpotomy. Sixty eight primary mandibular molars in 52 children between 5 and 9 years old were criteriously selected. Clinical and radiographic evaluations were recorded 3, 6 and 12-months postoperatively. No signs of clinical failure were observed at all follow-up appointments in both groups. Statistically signifcant difference between both groups was only observed when assessing tooth crown discoloration and pulp canal obliteration since all of the teeth treated with Portland cement presented dicrete grayish discoloration and root stenosis. Portland cement was equally effective as formocresol as pulp capping agent in pulpotomies of deciduous teeth. Although our results are very encouraging, further studies and longer follow-up assessments are needed in order to determine the safe clinical indication of Portland cement.

Pulpotomies with portland cement in human primary molars

Two clinical cases in which Portland cement (PC) was applied as a medicament after pulpotomy of mandibular primary molars in children are presented. Pulpotomy using PC was carried out in two mandibular first molars and one mandibular second molar, which were further followed-up. At the 3, 6 and 12-month follow-up appointments, clinical and radiographic examinations of the pulpotomized teeth and their periradicular area revealed that the treatments were successful in maintaining the teeth asymptomatic and preserving pulpal vitality. Additionally, the formation of a dentin bridge immediately below the PC could be observed in the three molars treated. PC may be considered as an effective alternative for primary molar pulpotomies, at least in a short-term period. Randomized clinical trials with human teeth are required in order to determine the suitability of PC before unlimited clinical use can be recommended.
