Pengaruh musik terhadap penurunan kadar mineral permukaan email pada kondisi defisiensi protein (Effect of music of the Decreased Enamel-Surface Mineral Content of Rat Teeth with Protein Deficiency

Protein deficiency could to enamel hypoplasia and decreased level of Growth Hormone (GH). Cell proliferation and synthesis of enamel-matrix which effect the mineralization process of the tissue, are stimulated by GH. Music was reported to be able to increase GH. Objective: analyzing the effect of music exposure since prenatal on the decreased Calsium (Ca) and Phosphor (F) content of the enamel-surface of rat-pups in protein-deficiency condition. Experiment: thirty-two rat of the first day of gestation period were devided into groups with and without music. Music were given twice daily, lullabies every early morning, and classic, baroc, and romantic music every evening. At 2-dayold the rat-pups were further divided into groups with normal diet contained 19,5% protein, and groups with protein deficiency diet contained 7,5% protein. At 2-and 5-weeks-old, 6 rat pups from each group were randomly terminated, the mandibles were dissected out, cut into hemi-mandibles, cleanedm and dried. The percentage of Ca and P content of the lower incisor enamel-surface was analyzed using, Energy Dispersive X-ray (EDX), data were analyzed using One Way ANOVA with ά0,05. Result: at 2-weeks-old the Ca (8,6%) and p (10,6%), contents of enamel-surface of pups with normal-diet and music were higher than the Ca (3,9%) and P (1,9%) content of enamel-surface of pups with protein deficiency with no music (P
