Modalities of Management of Impacted Canine - Pocket Dentistry Lack of space The radiographic interpretation of the SLOB rule is if, when obtaining the second radiograph, the clinician moves the x-ray tube in a distal direction, and on the radiograph the tooth in question also moves distally, then the tooth is located on the lingual or palatal side. Google Scholar. It then seems to be deflected to a more vertical position, and it finally erupts with a slight mesial inclination [1]. Patients may present at different ages and many cases will be incidental findings. should be compared together, if the PDC improved or was in the same position as before treatment in relation to sector or/and angulation, no intervention PDCs in group A that had improved in relation to sectors were 74% after one year and 79% after one year and Ectopic canines are most commonly involving the maxilla.

A mnemonic method for remembering this principle is the SLOB rule (same lingual opposite buccal). Today's anatomy is by request for the lateral fossa also known as the incisive fossa and canine fossa. Note the relationship of the cuspid to the roots of the adjacent teeth, nasal cavity and maxillary sinus. palpation of canine bulge should be done at the labial side near the occlusal plane and moving the finger upward as much as possible into the vestibule. 1968;26(2):14568.
