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.

Among the given sites, the lower lip is the most common location for squamous cell carcinoma of the lip/oral cavity in many populations, largely due to chronic actinic (sun) exposure, which predominantly affects the more exposed lower lip (as opposed to the upper lip, which is more protected). Overall, oral cavity SCC site frequency varies with risk-factor exposure (e.g., buccal mucosa and tongue are common with tobacco/betel use), but of the choices provided, lower lip carcinoma is classically taught as the most frequent.
