examining the root length, CBCT and periapical radiographs show similar values to the histological examination. Follow-up should be started 6 months after extracting primary canines by digital palpation at PDC area and taking a new panoramic radiograph. Dislodgement of the root apex may require a certain amount of torsion, as this is often curved. the patient should be referred to an orthodontist [9,12-14]. Clinical examination is key to early identification of ectopic canines. One RCT investigated the effect of unilateral extraction of maxillary primary canines, and surprisingly, no case of midline deviation after the unilateral
On the other hand, if the PDC position worsens in relation to sector or angulation,
If the root is >75% formed, the likelihood of requiring root canal treatment increases. 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. If necessary, the crown is then exposed after removal of the overlying bone. 1989;16:79C. In group 1 and 2, the average

Impacted mandibular canines are not as frequent as maxillary canines, and are usually found in a labial position. The chosen method would depend on the degree of impaction, age of the patient, stage of root formation, presence of any associated pathology, dental condition of the adjacent teeth, position of the tooth, patients willingness to undergo orthodontic treatment, available facilities for specialized treatment and patients general physical condition. Because of the significance of maxillary canines to aesthetics and function, such decision can have very serious consequences. Eur J Orthod.
