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.

For pulpectomy of primary teeth, the root canal filling (obturating) material must be resorbable at approximately the same rate as the primary tooth root, non-toxic to the succedaneous tooth germ, and easily removed if needed. Zinc oxide eugenol (ZOE) paste (plain or with iodoform, e.g., Vitapex/Metapex) satisfies these requirements and is considered the ideal/traditional obturating material for primary teeth. Gutta-percha, used in permanent teeth, is non-resorbable and unsuitable for primary teeth.
