A stomatological composition is provided. The stomatological composition is capable of stably compounding an antibody obtained from a hen egg yolk, and preventing diseases in an oral cavity such as odontonecrosis and periodontal disease from occuring or improving such diseases in the oral cavity. The stomatological composition includes at least one selected from the group consisting of lipase, protease and the antibody obtained from the hen egg yolk, citric acid and a metal salt of citric acid. A total amount of the lipase, the protease and the antibody obtained from the hen egg yolk is in the range of 0.001 to 10 wt%. When an amount of the citric acid is defined as 〝A〞 [wt%] and an amount of the metal salt of the citric acid is defined as 〝B〞 [wt%], the following relation is satisfied: 0.005A/B1. Further, the stomatological composition of the present invention includes a polyglyceryl fatty acid ester or an amino acid-based ampholytic surfactant as a surfactant. Further, the stomatological composition of the present invention includes collagens.本發明係提供一種可安定地調配雞蛋抗體,且可預防或改善齲齒、牙周病等口腔內疾病之口腔用組成物。該口腔用組成物含有選自脂酶、蛋白酶及雞蛋抗體所成群之至少1種,檸檬酸與檸檬酸金屬鹽。脂酶、蛋白酶及雞蛋抗體之總調配量較佳係0.001至10wt%。將檸檬酸的調配量當作A[wt%]、檸檬酸金屬鹽的調配量當作B[wt%]時,較佳係滿足0.005≦A/B≦1之關係。又,本發明之口腔用組成物較佳係含有聚脂肪酸甘油酯或胺基酸系兩性活性劑作為界面活性劑。又,本發明之口腔用組成物較佳係含有膠原蛋白類。
