[Research progress in ecological prevention of dental caries].

Dental caries is one of the most common oral diseases around the world. Dental plaque attached to the surfaces of teeth is the main biological factor leading to caries. Although fluoride is still one of the most commonly used methods to prevent caries, with the change of epidemiological characteristics of caries and the update of the understanding of caries etiology, it is necessary to use other ecological methods such as antimicrobial peptides, arginine, probiotics and natural products, etc. to enhance the effect of fluoride in preventing dental caries. The present article reviews the research progress on the ecological approaches for caries prevention in recent years.龋病是世界范围内最普遍的口腔疾病，附着在牙表面的牙菌斑是导致龋病的主要生物因素。虽然应用氟化物仍然是预防龋病的主要手段，但随着龋病流行病学特征的变化以及人们对龋病病因认识的更新，有必要使用其他生态学方法（如抗菌肽、精氨酸、益生菌、天然产物等）辅助氟化物的防龋效果。本文对近年来生态防龋的研究进展作一综述。.
