“…They definitely lack the contribution of other dental specialties as radiologists, surgeons and even general practitioners, as well as the comparison with a more objective gold standard which is the actual treatment duration and protocol applied for each case with all faced difficulties. These recommendations were approved by other previous studies 30,31,33 .…”

Objectives: The aim of this study was to compare and evaluate the guidelines proposed by Counihan et al 2013 and the KPG index method for assessment of maxillary impacted canine position using CBCT images from a radiographic point of view. Subjects & methods: Thirty-six CBCT scans of 36 patients (6 males and 30 females), with a total number of 45 impacted maxillary canines, were recruited from the database of the Oral and Maxillofacial Radiology Department, Faculty of Dentistry, Cairo University. KPG index, for each impacted canine, was calculated by giving both its cusp and root tips a score on a 0-5 scale along the x, y, and z planes. The summation of these six scores would predict the treatment difficulty, classified as easy (0-9), moderate (10-14), difficult (15-19), and extremely difficult (20 and above). Moreover, Counihan et al 2013 guidelines were applied on each studied impacted tooth in which the tooth position in four categories was considered: overlap with adjacent incisor, vertical height, angulation to midline and position of root apex. For each category, either good, average or poor prognostic outcome was selected. Data were collected and statistically analyzed. Results Upon comparing both studied methods of radiographic assessment of impacted maxillary canines, a statistically significant difference was found: KPG index categorized more cases (9 cases) as easy (20%) while Counihan et al guidelines categorized only 2 cases (4.4%) as having good prognosis. Similarly, KPG index categorized more cases (15 cases) as moderate (33.3%) while Counihan et al guidelines categorized 13 cases (28.9%) as having average prognosis. On the other hand, Counihan et al guidelines categorized more cases (30 cases) as poor prognosis (66.7%) while KPG index categorized only 21 cases (46.7%) as being difficult. Nonetheless, on comparing the treatment difficulty and prognosis of impacted maxillary canines found on the right and left sides, unilaterally or bilaterally, in males and females, a non-statistically significant difference was found using both methods of radiographic assessment. Conclusion From a radiographic point of view, the KPG index, with some minute modifications, has demonstrated to be an effective and competent method for classification of maxillary impacted canine's treatment difficulty in accordance to their position, as compared to the guidelines proposed by Counihan et al at 2013.

“…As a result, the main advantage of CBCT versus a CT scan is the lower radiation exposure. 16 The use of CBCT can surely aid in the accurate and quick diagnosis and the appropriate therapeutic intervention. 48,83 The esthetic outcome of 16 patients treated with the forced eruption of unilaterally impacted canines was assessed in a retrospective study.…”

“…After that, the cumulative score is used to evaluate the difficulty of surgical and orthodontic treatment. Every impaction was categorized into easy (0-7), moderate (8)(9)(10)(11)(12)(13)(14), difficult (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19), and extremely severe (20+) difficulty levels.…”

“…12,13 Two-dimensional (2D) radiographs have traditionally been used to detect impacted canines in various populations, including Italian, 14 Swedish, 15 and Turkish. 16 However, employing 2D radiography methods to find impacted canines has significant limitations, including anatomical structural distortion and superimposition. 17 Furthermore, the KPG index was not verified as a reliable method of evaluating treatment time and difficulty of surgical treatment for impacted canines in a study by Kau et al 18 Another drawback of the study by Kau et al 18 was the small sample size.…”

“…The cumulative score is used to predict the treatment's difficulty. Every impaction was graded into four levels: easy (0-7), moderate (8)(9)(10)(11)(12)(13)(14), difficult (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19), and extremely difficult (20+). Four canines were graded as easy, eleven as moderate, nine as difficult, and four as extremely difficult.…”

This review covers all aspects from the viewpoint of impacted canines that were missed by some articles. Most review studies focus on the epidemiology and incidence of the disease but rarely on the detailed investigation of this therapeutic disorder; therefore, appropriate awareness of canine impaction diagnosis and management is critical prior to any orthosurgical treatment procedures. Hence, it is crucial to emphasize the means of proper diagnosis and interception of this clinical condition. This study aimed to compare and review the various diagnostic methods used to identify canine impaction, its advantages, shortcomings, research, and clinical implications to guide the evaluation and management of cases in general dental practice. Based on the current literature, the epidemiology of canine impaction, diagnosis, classification systems, and surgical options for exposing impacted canines are discussed. To determine the anatomical position of impacted canines, a thorough clinical examination and appropriate diagnostic imaging should be performed. The surgical method for exposing impacted canines should consider the tooth’s anatomical position in regard to the alveolar ridge and the amount of keratinized mucosa/gingiva. The article concludes that displacement and non-eruption of impacted canines can be managed by administering an accurate and adequate diagnosis of canine impaction, proper investigation of tooth position, length, direction, and related structures, selecting the appropriate management approach, and also reducing the biomechanics involved during canine retraction using fixed orthodontic appliances when they are impacted, and thus can restrict the risk of s urgical t rauma o n t he a djacent h ard a nd s oft t issues in th e p atients .

Maxillary canines are the second most frequently impacted teeth after the third molars. Bucco-palatal localization is the primary diagnostic task during radiographic examination of impacted maxillary canines for proper treatment planning. Such localization is done by a combination of clinical and radiographic findings. However, it is necessary to identify cases requiring 3D cone-beam computed tomography (CBCT) scans in addition to 2D orthopantomograms (OPG) for accurate diagnosis.OPG and CBCT images of 75 impacted maxillary canines (IMC) were included in the study. Each OPG was evaluated for magnification index. The data obtained was tabulated and subjected to statistical analysis.The present study revealed higher prevalence of impacted maxillary canines in females (73%), with a slightly higher prevalence on the left side (53%). Most of the impacted canines were present in the mid-alveolus region. All the cases had 100% concordance between OPG and CBCT while locating palatal and mid-alveolar impacted canines whereas for buccally impacted canines, the concordance between OPG and CBCT was 93%.Early radiographic examination and diagnosis are essential to recognize impacted maxillary canines. The sequela of delayed eruption or treatment of impacted canines may be severe resorption of the adjacent lateral and central incisors.
