ABSTRACT
Objectives:
The aim of this report is to present the results of a scanning electron microscopic study on the presence of matrix vesicles (MVs) found in human dentine. StudyDesign:
Dentin tissue from 20 human bicuspids was analyzed by means of scanning electron microscopy.Results:
MVs were found as outgrowths of the cellular membrane of the odontoblastic body, the more proximal portion of the odontoblastic process before entering the dentinal tubule and in the odontoblastic process within the inner third of the dentin. Size of MVs varied depending on location. In the inner third of dentin, they were seen indiverse positions; as membranal outgrowths, deriving from the odontoblastic process, lying free in the intratubular space and attached to the dentinal wall. Sometimes, they were seen organized forming groups of different size sand shapes or as multivesicular chains running from the surface of the odontoblastic process to the tubular wall. MVs were present in places never considered 1) the body of odontoblasts; 2) the most proximal part of the odontoblastic processes before entering the circumpulpal dentine and also 3) in the inner third of dentinal tissue.Conclusions:
According to our results, MVs not only participate during mantle dentin mineralization during early dentinogenesis, they also contribute during the mineralization process of the inner dentin (AU)
