Histological, ultrastructural and quantitative investigations on the response of healthy human pulps to experimental capping with Mineral Trioxide Aggregate: a randomized controlled trial. 2008.

摘要

Aim To investigate the pulpal response to direct pulp capping in healthy human teeth with mineral trioxide aggregate (MTA) as against calcium hydroxide cement (Dycal~R) as control.Methodology Twenty healthy human third molars had iatrogenic pulpotomy and direct pulp capping with MTA. Another 13 teeth were capped with Dycal~R as controls. The teeth were restored, with IRM~R, clinically reviewed and extracted after a number of pre-deter-mined intervals (1 week, 1 month and 3 months). The specimens were fixed, decalcified, subdivided axially into two halves in the oro-buccal (lingual-buccal) plane, embedded in plastic, serial sectioned and evaluated qualitatively and quantitatively by correlative light and transmission electron microscopy with appropriate statistical evaluation of the quantitative data.
