Pulp condition of successfully formocresol‐treated primary molars

Abstract

abstract— The aim of the study was to assess the state of the pulp of primary teeth successfully treated by formocresol pulpotomy. Nineteen teeth, all of them with clinically and radiographically successful treatments, were extracted 3–24 months after treatment. The pulpal condition had changed in all the teeth. Inflammatory reaction or necrosis was observed in all teeth. Dentinal resorption followed by apposition of hard tissue were common findings. In the teeth with vital tissue only in the apical area, the tissue had minor or no signs of inflammation. Microorganisms could be demonstrated in the necrotic tissue in one tooth. The wide range of pulpal conditions observed indicated that there was no typical tissue reaction to formocresol even though treatment was clinically successful. The present study confirms that the formocresol method should be regarded only as a means to keep primary teeth with pulp exposures functioning for a limited period of time.

Formocresol and alternative primary molar pulpotomy medicaments: a review

“…The histologieal effect of glutaraldehyde has been compared to previous work involving formaldehyde (6,20). Glutaraldehyde produced no multizoning, but a more homogenous, eosinophilic compressed zone below^ the amputated surface.…”

“…Many studies state that formocresol application produces distinct zones within the pulp (6,10,19,20). The origin of the unaltered apical tissue has been cause for debate.…”

Endodontic Management of a Mature Mandibular First Permanent Molar That Survived for 20 Years after Complete Pulpotomy: A Case Report

“…Calcification of canals with formocresol pulpotomy is among the most common radiographic findings and it is reported in up to 80% of cases (Willard, 1976). This can be explained due to the inflammatory reaction between the vital radicular tissue and formocresol fixed tissue that forms reactionary dentine, followed by dentinal resorption and hard tissue deposition along the canal walls (Røolling and Lambjerg-Hansen, 1978). Another explanation can be due to the result of exaggerated odontoblastic or odontoblastlike cells activity.…”

Pulpotomy Medicaments used in Deciduous Dentition: An Update

“…This outcome is more likely in children treated under general anesthesia, and the possibility of systemic toxicity has been reported to be much higher in such cases. Other studies 27,67 have reported certain side effects from the use of formocresol in clinical and histological studies, as well as several combinations of irregular pulp responses. These responses have included normal pulp, fibrosis, necrosis, hyperemia, inflammation, internal resorption, granulation tissue and osteodentin.…”
