Pedo vs Materials — Key differences for NEET MDS
First primary tooth = mandibular central incisor at 6 months. First permanent tooth = mandibular first molar at 6 years. Natal teeth = present at birth. Neonatal teeth = first 30 days. Nolla stages of tooth development 0 to 10. Primary dentition complete by 2.5 to 3 years. Ugly duckling stage = normal spacing 8-9 years. Mixed dentition = 6 to 12 years.

Polysulfide = longest setting time messiest = lead dioxide accelerator. Polyether = stiffest most hydrophilic = initial rigidity. Alginate = irreversible hydrocolloid = snap set. Agar = reversible hydrocolloid = high detail low strength. Impression plaster = most rigid.
