Pulpal status of hypomineralized permanent molars.

摘要: Purpose Young patients with hypomineralized teeth frequently complain of symptoms suggestive dentin hypersensitivity. It has been proposed that these may be exacerbated by an underlying pulpal inflammation. The purpose the study was to determine status teeth. Methods experimental material comprised 25 sound and 19 permanent first molars obtained from children requiring dental extractions under general anesthesia. Pulp sections were processed for indirect immunofluorescence using combinations of: (1) protein gene product 9.5; (2) leukocyte common antigen; (3) Ulex europaeus I lectin. Image analysis then used percentage area staining each label. Results Innervation density significantly greater in pulp horn subodontoblastic region than Immune cells most abundant within pulps exhibiting enamel loss. Vascularity found similar both teeth, but hypersensitive samples. Conclusion This provides biological evidence inflammatory changes present tissue
