Abstract :

Background: Amelogenin is a major protein constituent of the developing enamel matrix that is critical for enamel formation. Mutations of amelogenin cause hypoplastic enamel phenotypes. Previous research found that infant of diabetic mother has higher risk for having enamel hypoplasia. Purpose: The aim of this study was to determine the effect of gestational diabetes mellitus on the expression of amelogenin in rat offspring tooth germ. Methods: Sixteen female Wistar rats, aged 2.5-3 months, body weight 150-200 g were used in this study, mated then divided into two groups and treated on day 0 of pregnancy. Group A was DM group, consisting of 8 rats, induced by streptozotocin (STZ) injection 40 mg/kg BW. Group B was control group, consisting of 8 rats received citrate buffer injection. Thirty-two rat pups were decapitated on day 5. Immunohistochemical procedures were performed on molar tooth germ of the mandibular rat pups using antibody anti-AMELX to determine the expression of amelogenin. Examination carried out on the images using ImageJ software. All data were then statistically analyzed by Mann Whitney test. Results: There was no significant difference in the expression of amelogenin in the DM group and control group (p>0.05). Conclusion: Gestational diabetes mellitus did not affect the expression of amelogenin in rat offspring tooth germ. Further study is needed to clarify the pattern of amelogenin expression with measurement of glucose levels of rat pups.
