A 9 year old male patient reported to the department of pedodontics and preventive dentistry Dr R Ahmed Dental College & Hospital with the chief complaint of unaesthetic upper front teeth on clinical examination. It was found that the upper central incisors were markedly large in size with buccolingual grooves present partially separating two halves of crown.
