“…Additionally, Queck et al 2003 suggested that the gender differences may be caused by the fact that the skull and jaw sizes are smaller in women than in men and a proper jaw size is an important factor that helps the development and eruption of teeth in exact order and place 24 . However, other studies as Pico et al 2017 found the number of male and female patients in a ratio of 1:1 and justified that by their reduced sample size (only 28 impacted canines in 20 patients) 25 .…”

“…In the current study, 75% of maxillary impacted canine cases were unilateral while only 25% were found bilaterally. Similarly, Pico et al 2017 found that the frequency of unilateral and bilateral impactions was 60% and 40% respectively 25 . Moreover, another previous study showed that the majority of impactions of maxillary canines are unilateral at 92%, and only 8% are bilateral 27 .…”

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.

“…It has shown varying insights and conclusions. Pico et al [ 42 ] stated in 2017 that further research is necessary to prove when CBCT has a clear advantage over conventional 2D radiographs. In 2019, Björksved et al [ 43 ] concluded that “panoramic radiographs could be considered good enough for rendering palatally displaced canine position when the need for 3D information is not crucial for treatment planning”.…”

Objectives Radiographs are considered essential in orthodontics. However, their diagnostic value and indications for use are still uncertain, while exposure to radiation carries health risks. This study aimed to report on the development of a clinical practice guideline on orthodontic radiology. Methods A Guideline Development Taskforce was set up. The GRADE methodology was used for development and the RIGHT Statement for reporting of the guideline. We systematically reviewed articles to address the main clinical question: how different types of radiographs contribute to orthodontic diagnosis, treatment planning and post-treatment outcome evaluation. After a literature search and data extraction, we formulated conclusions and assessed the strength of the evidence according to the GRADE method. Both literature conclusions and the most important considerations, such as patient preferences, organizational matters and expert opinions were taken into account to finally issue recommendations. Results 7 clinical questions focused on orthopantomograms, lateral cephalograms, hand-wrist radiographs, peri-apical radiographs, bitewings, antero-occlusal radiographs, and cone-beam computer tomographic imaging. The literature search lead to 484 unique studies, of which 17 were included in the analysis. The strength of evidence of the conclusions was graded low or very low. We formulated considerations and took them into account when issuing the 13 clinical recommendations to address the clinical questions. Conclusions There was a considerable lack of scientific evidence on this topic. Nonetheless, this guideline provides clinicians with a tool for decision-making regarding radiographic records while enhancing patient radiation protection. More research of higher quality is recommended for a future update.

“…In previous studies, the authors compared CBCT and OPG on many different aspects such as: surgical technique of maxillary and mandibular third molar, classifying of lower third molar, upper molar root protrusion into maxillary sinus, relation of impacted mandibular third molars to the inferior alveolar nerve, presurgical evaluation of bony implant sites, impacted maxillary canines, and anatomical characteristics and visibility of mental foramen and accessory mental foramen (Ghaeminia et al,2009;Aravindaksha et al, 2015;Lorenzo et al, 2015;Pico et al, ;Araujo et al, 2019;Hermann et al, 2019;Brasil et al, 2019;Themkumkwun et al, 2019;Nirmalendu et al, 2019;Fortes et al, 2019). None of the prior studies compared CBCT and OPG films taken after the marsupialization of odontogenic cysts in terms of evaluating whether the odontogenic cyst volume allows enucleation.…”

“…According to their results 83.87% of the mental foramens and 45.83% of the accessory mental foramens identified on CBCT were also visible on panoramic images. A questionnaire implemented by Pico et al (2017) reported that the CBCT imaging gave further information when compared to panoramic radiography regarding the impacted upper canine assessment. This questionnaire was performed with nine orthodontists and they were asked to analyze different topics regarding the impacted maxillary canines.…”

Objective: We explored the utility of Cone Beam Computed Tomography (CBCT) and Orthopantomography (OPG) in terms of treatment planning to determine which form of radiography can more reliably assess cyst volume. Methods: 'We evaluated the panoramic and CBCT images of nine patients who consulted our clinic for treatment of large cystic lesions. Overall, 27 images were reviewed and analyzed by 21 oral and maxillofacial surgeons. We asked five questions (detailed in the main text). Results: We evaluated the 189 answers in the questionnaire. The surgeons recommended marsupialization followed by enucleation, marsupialization, and enucleation (70.89 %, 14.28 %, and 14.81 %, respectively). The answers to the reasons of these treatment choices showed that the size of the cysts and relationship with the adjacent anatomical structures are the most effective factors. In after marsupialization challenges, 85.71% of the answers considered that the lesion had shrunk sufficiently to allow enucleation according to OPG's, however, this rate decreased to 42.23% when the same surgeons evaluated the CBCT images of the patients after marsupialization. Ninety-nine percent of the responses reported that CBCT was much more reliable than OPG. Conclusion: In this study, we concluded that OPG imaging method can be used for the diagnosis and followup of cystic lesions, but in order to determine the accuracy of timing, adequacy of new bone formation and whether the cyst has shrunk sufficiently in volume, during the transition from the marsupialization process to the enucleation process, it is necessary to use CBCT imaging method. Further clinical trials should be conducted to define the effects of three dimensions images regarding surgical treatments of different kinds of oral and maxillofacial region cystic lesions.
