Abstract

Background: This study designed to shade light on the important role of CBCT in accurate localization of theimpacted maxillary canines.Materials and method: Fifty two unilateral and bilateral impacted maxillary canines from 30 patients (24 females and6 males) were evaluated by a volumetric 3D images obtained from cone beam CT. All samples attended to thespecialist health center of dentistry in Al-Sadder City referred to CBCT by oral surgeons or orthodontists to detect theexact position of impacted upper canine in cases when there was no bulging buccally or palatally which aids todetect the exact position.Results: Mesio-palatal angulations had the highest rate (63.5%) followed by mesio-labial (19.2%), vertical (labial)(9.6%), disto-palatal (5.8%) and disto-labial (1.9%). The relation between impacted canine and the adjacent teethregarding to the attachment was significant only with lateral incisor. No cases of root resorption of the adjacentteeth were recorded. Bilateral impacted teeth were found in 22 patients which is highly significant (especially infemales), while unilateral impaction was found only in 8 patients especially in females. Impacted canine was moreprominent in female whether unilateral or bilateral.Conclusions: CBCT imaging of impacted canines can show the following: presence or absence of the canine,angulations of the long axis of the tooth, relative labial and palatal positions and proximity to adjacent teeth. In short,CBCT imaging is clearly advantageous in imaging and management of impacted canines

Abstract

Background: Maxillary canines are important aesthetically and functionally, but impacted canines are more difficultand time consuming to treat, the aim of this study is to investigate with multi-detector computed tomography thecorrelation between the bone density and the upper canine impaction.Material and method: A sample of Unilaterally impacted maxillary canines from 24 patients (19 female, 5 male) whowere referred to accurately localize the impacted canines at al- Karkh general hospital were evaluated by avolumetric 3-d images by the multi-detector computed tomography to accurately measure the bone density of themaxillary cortical palate of the maxillary impacted canine side and compare it with the other side of the normallyerupted canine.Results: The statistical descriptive analysis showed that the ratio of the maxillary canine impaction was higher infemales than in males, also the it revealed that the mean bone density of the cortical bone was greater in themaxillary impacted canine side (affected side) than in the control side (the side of the normally erupted canine), theWilcoxon signed ranks test showed a significant difference in the mean bone density between the affected side andthe control side.Conclusions: The increased bone density of the maxillary cortical plate could be an obstructive factor that causemaxillary canine impaction

Abstract

Background Cone Beam Computed Tomography system of 3D digital acquisition can be used in various dental sections such as orthodontics, endodontic, implantology, surgery and oral diagnosis. Linear and angular measurements on Cone Beam Computed Tomography images are accurate, precise and can be used to assess the exact position of displaced canines. Objectives It is to investigate with cone beam computed tomography the correlation between the palatal depth, width and the upper canine impaction. Materials and methods The study sample consists of 57 CBCT images of 35 patients referred to Al- Shifaa private hospital with impacted maxillary canines and 22 control patients with fully erupted canines. These were evaluated by volumetric 3D imaging to accurately localize the normal or impacted canines. The palatal depth and width of the impacted canine and control cases were measured and compared.Results The statistical descriptive analysis showed no significant difference in palatal width measurements between the control and impacted canine groups. On the other hand, the LSD test showed a significant difference in the mean of palatal depth between the control cases and impacted canine cases. Conclusions Marked decreased palatal depth in impaction cases could be a factor in causing maxillary canine impaction
