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.

Glass ionomer cement releases fluoride ions over time (and can also recharge/re-release fluoride after topical fluoride exposure), which helps inhibit demineralization and promote remineralization of adjacent tooth structure, giving it an anticariogenic (cariostatic) property. This is generally the intended meaning of the question ("anti-carcinogenic" is a likely typographical rendering of "anti-cariogenic" in the source material). None of the other cements listed (polycarboxylate, zinc phosphate, zinc oxide eugenol) have a clinically significant fluoride-release/anticariogenic effect comparable to glass ionomer.
