    • ទាំងអស់ខាងលើ

    Correct Answer
    A. ការព្យាបាលដោយថែទាំ(preventive treatment plan)
    Explanation
    The correct answer is "ការព្យាបាលដោយថែទាំ(preventive treatment plan)". This is because early caries refers to the initial stages of tooth decay, where the enamel is beginning to break down but the cavity has not yet formed. Preventive treatment plans focus on strategies to stop the progression of caries and prevent further damage to the tooth. This can include measures such as regular dental cleanings, fluoride treatments, and dental sealants to protect the tooth from decay.
