... by approximately 40% of patients. 35,36 Radiographically, keratocystic odon- togenic tumors demonstrate a well-defined unilocular or multilocular radiolucency with smooth or scalloped and often corticated margins. Keratocystic odontogenic tumors tend to grow in an anteroposterior direction within the jawbone without causing considerable expansion (Fig. 6). Maxillary lesions are usually smaller than mandibular le- sions. Keratocystic odontogenic tumors can also present as an interradicular radiolucency, similar to lateral peri- odontal cysts. [35][36][37] In some instances, dystrophic calcifica- tions may develop in long-lasting cysts as small radiopac- ities. ...

Management of impacted canines includes an interdisciplinary approach to achieve desired esthetics, and functional, and occlusal treatment goals. The present case series included various surgical procedures, used for the management of impacted canines and it also highlights the periodontal and orthodontic considerations to be taken before surgical canine exposure. The surgical exposure of canine creates a sufficient space and view of teeth that helps in the proper orthodontic extrusion and traction of teeth into the dental arch.
... Radiographs should be taken after every 6 months to 1 year to see if the impacted tooth is causing any problem or not. [36][37][38] The other treatment option will be to extract the impacted canine if proper occlusion is present, given that the lateral incisor and first premolar are in good proximal contact, as pathological growth is associated with the impacted canine, making it challenging to bring it correctly into the arch. ...
Objectives. This study aimed to analyze the inter-molar width and skeletal base class to predict maxillary canine impaction in permanent dentition. Methods. This cross-sectional study was carried out between September 2021 to March 2022. Patients aged between 13 and 20 years were recruited. These patients’ cone-beam computer tomography(CBCT), lateral cephalogram, and dental casts were collected and analyzed. For statistical analysis, T-test and Chi-square tests were applied. Results. A total of 92 patients were enrolled in this study. Inter-molar width was significantly decreased in patients with impacted canine(P < .001). The skeletal base classification was statistically significant when compare with intermolar width(P < .05). The location of impaction (P = .060), type of impaction(P = .435), and side of impaction(P = .239) were determined to be statistically insignificant. Conclusion. The Inter-molar width was decreased in patients with impacted canine; therefore, it may be a potential risk factor. The skeletal classification was found to affect inter-molar width in impacted canine patients.

Objective
The aim of this study is to evaluate the knowledge and awareness levels of patients who have at least one impacted tooth and who had previously applied to the dentist.
Study design
This study was conducted in patients aged 15 years and older who applied to Ordu University Faculty of Dentistry for routine examination and agreed to fill out the questionnaire form. A total of 325 people participated in the survey conducted to determine the awareness of patients applying to the faculty of dentistry about their existing impacted teeth. A Pearson's chi-square test was used for hypothesis testing when expected frequencies exceeded 5.
Results
It was determined that 56.9 % (185) of the participants were aware of their existing teeth, while 43.1 % (140) were not aware. When the patients were evaluated according to the institutions they had visited, it was seen that the group who were most aware of the presence of impacted tooth were those who apply to the faculty of dentistry (74.4 %). The rate of being informed by dentists in the institutions that they had previously visited was higher in patients with university or post-university graduates (p < 0.05). The most common information given by the dentists to the patients about their impacted dental problems was that the tooth should be followed up (40.4 %), while the removal of the tooth constituted 28.4 % of the information given.
Conclusion
This study showed that although patients are aware of their existing impacted teeth, their level of knowledge about the risks it may pose is low. For a healthy oral care and health, patients should be adequately informed about impacted teeth.
... 7 Panoramic radiography is the primary imaging method to detect and evaluate impacted teeth, surrounding tissues, and any possible pathologies including cysts and tumors. 9 Especially in the evaluation of third molars, it is an important initial tool, with a specificity ranging from 96% to 98%, to determine any possible injury to surrounding vital tissues such as inferior alveolar nerve injury. 10 Most often impacted teeth remain asymptomatic; however, impaction of teeth may lead to complications with different severities. ...

Abstract Objective: The aim of this study was to assess the prevalence of impacted teeth and the frequency of associated pathologies by panoramic radiography retrospectively. Methods: This study was performed on digital panoramic x-ray images of a total of 688 subjects. The presence of impacted teeth was classified as third molar, canine, premolar, and supernumerary. Impacted teeth were evaluated in terms of cysts, abscesses, or caries. Patient files were reviewed to see if the impacted teeth were asymptomatic and required removal. Descriptive analyses were performed with GraphPad Prism 8.0. Results: Impacted teeth were present in approximately 22% of the patient group. The third molars were the most prevalent impacted teeth, with approximately 92% of all impacted teeth, followed by canines and supernumerary teeth. A pathology was detected in 38 out of 335 of the impacted teeth. Among the patient group, only 12 patients had symptomatic teeth and required removal of the impacted teeth. Conclusion: Impacted teeth are common and can cause a pathology. The most commonly impacted teeth are third molars with a predi-lection for the mandible. Even though most impacted teeth remained asymptomatic, a follow-up is required to monitor possible changes in the future.
... In the literature, the most commonly impacted teeth are the upper canines, third molars, mandibular and maxillary premolars, as well as the upper central incisors (20). In the current study, impaction was the most frequently recorded dental anomaly, with a prevalence of 23.7%. ...
Background: Dental anomalies (DAs) represent a significant chapter in pediatric dentistry with a lot of practical relevance. Both primary and permanent dentitions may be affected. Objective: The main objective of our study was to evaluate, using digital panoramic radiographs, the prevalence, distribution, and patterns of DAs in a sample of Lebanese children aged between 8 and 15 years old. Methods: 112 digital panoramic radiographs of patients aged between 8 and 15 years (60 males and 52 females) from the year 2017 till 2022 attending the department of Pediatric Dentistry and Dental Public Health at the Faculty of Dental Medicine at the Lebanese University were assessed for DAs of number (hypodontia, oligodontia, hyperdontia), of size (microdontia, macrodontia), of shape (fu-sion, gemination, dilaceration, taurodontism), of position (transposition, ectopia, impaction), and of structure (dentin dysplasia, amelogenesis im-perfecta, dentinogenesis imperfecta). The data were analyzed statistically using Chi-square and Fisher's exact tests. Results: Out of 112 patient radiographs, 84 showed at least one DA, which suggests a very high prevalence (75%). Among them, 36.9% exhibited multiple types of anomalies. These 84 patients showed a total of 274 DAs, distributed equally among males and females. Conclusion: Dentists should be alerted to the presence of DAs. Their high prevalence requires careful clinical and radiological examinations for early detection. Regular monitoring is mandatory and could guide preventive approaches to minimize associated dental complications.

Background: A dentigerous cyst is the second-most frequently observed odontogenic cyst, and an ameloblastoma is one of the most frequently observed odontogenic tumors. Both are mostly associated with an impacted mandibular third molar and have similar characteristics. Diagnostic difficulties often result in misdiagnosis and remain a challenge to overcome. Comprehensive clinical, radiographic, and histopathological views are essential to correctly diagnose the problem and formulate the most suitable treatment plan. Purpose: This case report aims to present a thorough approach to the diagnostic and surgical procedures involved in treating a dentigerous cyst that resembles an ameloblastoma by using marsupialization followed by enucleation. Case: This article presents the case report of a 27-year-old male patient with an infected dentigerous cyst resembling a unicystic ameloblastoma associated with a totally impacted lower mandibular left third molar. The patient had a history of swelling, pain, and pus drainage in the retromolar area. Symptoms subsided after antibiotic and analgesic prescriptions, but the lesion remained and was slowly progressing. The diagnostic approach began with a fine-needle aspiration biopsy, and the result confirmed a benign cystic lesion that was suspected to be an odontogenic tumor. Then an incisional biopsy was conducted under local anesthesia, diagnosing an infected dentigerous cyst. Case Management: Marsupialization and decompression using an obturator was preferred, followed by enucleation. Nine months later, a radiographic examination revealed satisfactory bone regeneration without recurrence. Conclusion: An incisional biopsy plays a vital role in establishing a definitive diagnosis. Marsupialization followed by enucleation offers an excellent combination of treatments achieving complete cyst removal, anatomical structure preservation, and bone regeneration with minimal complications.
... Maxillary incisor is rarely impacted, but the resulting malocclusion is conspicuous, adversely affecting the smile esthetics and phonetics among others, which could result in low selfesteem among patients [2]; thus, requires early orthodontic intervention. Tooth impaction may also lead to several pathologic conditions like external root resorption of the adjacent teeth, dentigerous cyst, and odontogenic tumors [3,4]. ...
Impaction of teeth affects patients’ esthetics, speech, and masticatory efficiency. In addition, the transposition of teeth makes a case difficult to manage. This case report describes a case of a 14-year-old boy with the impaction of the maxillary right central incisor and canine along with the transposition of the right canine and lateral incisor. The impacted teeth were surgically exposed and guided into the arch using orthodontic traction. Likewise, the transposition was corrected orthodontically by moving the teeth to their desired position without any detrimental effect on the adjacent teeth. The patient’s esthetics and occlusion improved substantially after the orthodontic intervention.
... It may lead to delayed eruption, mobility, and tooth displacement 5 . AFO lesions are typically recognized as unilocular masses on radiographic images with defined limits, presenting with variable amounts of calcified material in the internal structure 6 . The histological characteristics of AFO are similar to those of AF, with nests and cords of odontogenic epithelium in an ectomesenchyme as in the dental papilla. ...
... The detection of AFO lesions is possible generally upon routine radiographic examination or during the investigation of a missing tooth 7,9 . Radiographic images of AFO lesions often show unilocular masses, although they can be multilocular and associated with an unerupted tooth, which may be dislocated 6 . The internal structure is often mixed with a radiolucent area adjacent to the well-defined margin. ...
... Typically, the lesion is mostly corticalized and may exhibit radiopacity that varies in shape and size internally. Some AFO lesions may present with a small amount of enamel matrix and dentin, displaying a radiolucent radiographic image [6][7][8] . These characteristics were consistent with the imaging findings in this case, which included a well-defined unilocular lesion, the presence of radiopaque material in the internal structure, and involvement of the unerupted third molar. ...
Objective: the present report describes the clinical, radiographic, and histopathological features of an ameloblastic fibro-odontoma (AFO) lesion. Case report: we report a clinical case of a 14-year-old boy with asymptomatic edema. Panoramic radiography detected a unilocular lesion with defined margins located in the posterior region of the mandible. The internal structure of the lesion presented several degrees of radiopacity with the involvement of the third molar. Cone-beam computed tomography revealed expanded buccal and lingual cortical bones, perforation of the lingual cortical bone, and displacement of the mandibular canal. AFO was suspected based on the radiographic and clinical characteristics. Total excision was performed and histologically examined, confirming the diagnosis of AFO. No recurrence occurred during a 24-month follow-up period. Final considerations: the evaluation of the clinical, radiographic, and histopathologic findings needs to be accurate for a correct diagnosis and appropriate treatment for case of AFO since the presentation is often asymptomatic.Keywords: odontogenic tumors; radiography panoramic; cone-beam computed tomography.
