Cone-beam computed tomography findings of impacted upper canines

Abstract

PurposeTo describe the features of impacted upper canines and their relationship with adjacent structures through three-dimensional cone-beam computed tomography (CBCT) images.Materials and MethodsUsing the CBCT scans of 79 upper impacted canines, we evaluated the following parameters: gender, unilateral/bilateral occurrence, location, presence and degree of root resorption of adjacent teeth (mild, moderate, or severe), root dilaceration, dental follicle width, and presence of other associated local conditions.ResultsMost of the impacted canines were observed in females (56 cases), unilaterally (51 cases), and at a palatine location (53 cases). Root resorption in adjacent teeth and root dilaceration were observed in 55 and 47 impacted canines, respectively. In most of the cases, the width of the dental follicle of the canine was normal; it was abnormally wide in 20 cases. A statistically significant association was observed for all variables, except for root dilaceration (p=0.115) and the side of impaction (p=0.260).ConclusionRoot resorption of adjacent teeth was present in most cases of canine impaction, mostly affecting adjacent lateral incisors to a mild degree. A wide dental follicle of impacted canines was not associated with a higher incidence of external root resorption of adjacent teeth.

Three‐dimensional position of impacted maxillary canines: Prevalence, associated pathology and introduction to a new classification system

“…When we consider gender, we observe that there is a striking higher frequency female patients within our population. This is in line with the findings in the current literature (da Silva Santos et al, 2014).…”

“…The maxillary impacted canine is more often located palatally (85%) than labially (15%) (Bishara, ; Cooke & Wang, ; Ericson & Kurol, ; Ferguson, ; Grover & Lorton, ; Warford, Grandhi, & Tira, ). Root dilaceration is reported to be present in up to 59.5% of the cases (da Silva Santos et al, ).…”

The Relationship between Dental Follicle Width and Maxillary Impacted Canines’ Descriptive and Resorptive Features Using Cone-Beam Computed Tomography

“…Recently, cone-beam computed tomography (CBCT) has become an alternative to conventional CT in diagnosis and treatment planning of impacted teeth [ 5 , 6 ]. Also, CBCT has many advantages, it is reliable, reduces distortion, costs less, and allows a diminished radiation dose [ 7 ]. Bjerklin and Ericson found that, after 3D assessment of maxillary impacted canines, orthodontic treatment plans were changed in nearly half of the cases [ 8 ].…”

Evaluation of Impacted Third Molar and Canınes with Cone Beam Computed Tomography

“…Gömülü maksiller kanin dişlerin, lateral dişlerde daha sık rezorpsiyona sebep olduğu yapılan çalışmalarda bildirilmiştir (8,13). Literatürdeki bazı çalışmalarda (9,24,25) komşu dişlerde görülen rezorpsiyon oranı %27 ile % 35 arasında değişirken çalışmamızda rezorpsiyon oranı %18 olarak bulundu. Bu oran çalışmadan çalışmaya değerlendirilen gömülü diş sayısının ve kullanılan görüntüleme yöntemlerinin farklı olması nedeniyle farklılık gösterebilir.…”
