The best medium to carry an avulsed tooth to the dental clinic is milk. Milk is ideal because: 1) Osmolality similar to tissue fluids maintains cell viability, 2) pH is compatible with periodontal ligament cells, 3) Low bacterial content reduces contamination risk, 4) Readily available in most situations, 5) Can maintain PDL cell viability for 1-2 hours. Buccal vestibule is good but not always practical for young children, water causes cell lysis due to osmotic pressure, and cotton causes dehydration. Milk provides the best storage environment for maintaining cell viability.

Down syndrome is characterized by large anterior fontanelles that close late, open sutures, slanting palpebral fissures (mongoloid), decreased sexual development due to hypogonadism, macroglossia (enlarged tongue), and enamel hypoplasia leading to increased caries susceptibility. These features are pathognomonic of trisomy 21. Other syndromes do not present with this specific constellation of findings.
