If the PDC could not be palpated, a panoramic radiograph is indicated. Patients in the older group (12-14 years of age) The object nearer to the tube appears to move in the opposite direction [Same Lingual Opposite Buccal (SLOB) rule]. Diagnostic radiographs are indicated if: - One or both canines are not palpable buccally above the root of maxillary primary canines or lower first or second premolars have erupted while the If there is any bone overlying the crown, it is removed and sharp edges are smoothened so that the crown lies in a saucer-shaped bony cavity. Again, check-up should be started with palpation at the PDC area labially and palatally.
