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.

Leukoplakia is defined by the WHO as a predominantly white patch/plaque of the oral mucosa that cannot be characterized as any other definable lesion, and it is the classic example of an oral potentially malignant (precancerous) lesion, carrying a defined risk of malignant transformation to squamous cell carcinoma. Hemangioma is a benign vascular lesion, mucositis is an inflammatory reaction, and epithelial fibrosis is a descriptive tissue change, none of which are classified as precancerous lesions in the same sense.
