When managing an avulsed tooth, which substance is suggested for storage to maintain vitality?

• A. Milk
• B. Saline solution
• C. Doxycycline
• D. Sodium bicarbonate

Answer: (C)

When it comes to managing an avulsed tooth, the key goal is to maintain the vitality of the periodontal ligament cells until the tooth can be replanted. Milk is recommended for storage because it contains a similar osmolality to that of human cells and is rich in nutrients, making it a viable option for preserving the vitality of the tooth. It provides a buffered system that helps sustain the cells, unlike saline solutions, which do not offer the necessary nutrients and might create a hypertonic environment that can lead to cell damage. Doxycycline, while it has antimicrobial properties and is sometimes used in dental procedures, is not appropriate for storing avulsed teeth, as it does not serve to maintain the vitality of the periodontal ligament cells effectively. Sodium bicarbonate would not be effective either, as it doesn't have the appropriate conditions for cell preservation. Therefore, milk is the recommended substance for storing an avulsed tooth, as it creates an ideal environment for maintaining the vitality of the root surface and periodontal tissues.
