The following results were found: patients in group 1 had 27% of PDCs erupted, while group 2 had 62.5 % erupted, 79.2% in group 3 15.8). No votes so far! Small areas of resorption are not of interest for general dentists or orthodontists (grade 1 and 2) since those teeth have a good prognosis on the long term The overlying soft tissue is simply excised to expose the crown. However, panoramic radiographs underestimated Alpha angle (not similar to Kurol angle) of 103 In case of suspicious of any increased resorption during 6 or 12 months follow up indicates the need to refer the patient Impacted canines can be detected at an early age, and clinicians might be able to Local factors may also play a role in canine impaction, and these include: A longer eruption path that the tooth has to traverse from its point of development to normal occlusion [1]. Alqerban A, Hedesiu M, Baciut M, Nackaerts O, Jacobs R, et al. If the canine bulge was not palpable, the palatal area also should be palpated to ensure that the canine bulge is not at the palatal area, which indicates maxillary canine location than VP technique, however, both techniques were poor at localizing the buccal ectopic maxillary canine [17]. Patients in group 1 had 85.7% successful canine eruption, 82% in group 2 and 36% in the untreated control group [10]. Surgical anatomy of mandibular canine area.

It is essential to diagnose and treat this condition early, to prevent the development of complications. On the other hand, PDCs in sector 3 and 4 have a lower success rate, which equals 64% [9]. As the buccal object rule states that the buccally located object moves in the direction of the x-ray beam, on changing the direction of x-ray beam, the position of the impacted canine can be determined.
