Ideal age of interceptive orthodontics is -
Interceptive orthodontics aims to intercept and correct a developing malocclusion at an early stage, before it becomes fully established. This window corresponds to the mixed dentition period (roughly 6–12 years), when both primary and permanent teeth are present. During this period, problems such as crossbites, crowding, habits (thumb sucking), and arch-length discrepancies can be corrected more easily because the jaws are still growing and teeth are still erupting, making treatment simpler and more effective than after the permanent dentition is fully established.

Heat generation during cavity/tooth preparation is a major cause of pulpal injury. Inadequate water/air coolant, excessive pressure applied on the handpiece/bur, and the use of dull (worn) cutting instruments all independently increase frictional heat generated at the tooth surface, which can be transmitted to the pulp and cause irreversible thermal damage. Since all three factors contribute to pulpal injury through the same underlying mechanism (excess heat), the correct answer is "all of the above."
