Answer: 2
The most important modification of amalgam restorations on primary teeth is cavity preparation (Answer: 2). Unlike permanent teeth, primary teeth have a thinner enamel layer and a larger pulp chamber relative to their size. Therefore, the cavity preparation must be done with caution to avoid pulp exposure and ensure the longevity of the restoration.

Pedodontics
Answer: 3
Head shape in Down's syndrome is typically brachycephalic.
Explanation: Down's syndrome, also known as trisomy 21, is a genetic disorder that can lead to a range of physical and developmental characteristics. One of the common features of individuals with Down's syndrome is a brachycephalic head shape. Brachycephaly is a condition where the head appears relatively broad and short, with the breadth being disproportionately greater than the length. This characteristic is due to the premature fusion of certain skull sutures, which can also result in a flattened facial profile and a shortened neck. While the head shape is not a definitive diagnostic feature, it is often present in those with the condition.
