“…In fact, most of the impacted teeth associated to an odontoma are located on anterior region of the maxilla or mandible (6). Impacted permanent incisors are generally associated to compound odontoma rather than complex type (18). Interestingly, our results showed significant association between odontoma and impacted teeth ( P <0.0001), emphasizing the importance of early diagnosis of the lesion and proper treatment.…”

BackgroundOdontomas are the most frequent odontogenic tumors in the oral cavity and can result in failure of eruption of permanent teeth or be associated with impacted teeth.Material and MethodsThe present study evaluated the prevalence of complex and compound odontomas in non-syndromic patients prior to the onset of orthodontic treatment. Panoramic radiographs of 4,267 non-syndromic patients were evaluated; 22 cases were included being 54.5% complex and 45.4% compound odontomas.ResultsThe sample was composed predominantly by White males with mean age of 14.5 years. Complex odontomas were commonly found in the maxilla (83.3%) while compound type was mostly located on mandible (60%), presenting a significant association (P=0.027). Moreover, odontomas were significantly associated with impacted teeth (P<0.0001). The most frequently odontoma-associated impacted teeth were lower canines, followed by upper central incisors and upper canines, while impacted teeth with no odontoma were predominantly upper canines, lower second premolars and upper second premolars. Compound and complex odontomas showed mean size of 10.5 and 7.25 mm, respectively, presenting significant association between lesion size and odontoma type (P=0.021).ConclusionsOdontomas affected mainly White male patients with mean age of 14.5 years, being the complex type commonly found in the maxilla and the compound type mostly located on mandible. Furthermore, odontomas were significantly associated with impacted teeth, affecting mainly lower canines. Early diagnosis and correct treatment are essential to avoid any complications, such as prolonged retention of primary teeth and delayed eruption of permanent teeth. Key words:Odontoma, odontogenic tumors, dental anomalies.

“…There is no agreement among researchers regarding the correlation of the occurrence of dilaceration with trauma within the incisors. Udoye [23] does not correlate trauma with dilaceration, whereas Tan [1] found a statistically significant relationship between these two variables. One of the arguments excluding only the traumatic etiology of dilaceration is the fact that it usually concerns a single tooth, while the injury of the deciduous teeth should also disturb the development of neighboring permanent tooth buds [6].…”

“…Possible failure of such a procedure may be caused by ankylosis, rupture of ligaments, external resorption of the root, or puncture of the root through the alveolar ridge after tooth splitting, which may lead to tooth pulp necrosis, necessitating endodontic treatment and apicoectomy [25][26][27][28]. The natural tendency of the teeth is their migration and slope towards the gap after the removed or missing tooth, which results in a reduction or total lack of space in the arch for the missing tooth [1]. This situation enforces the implementation of orthodontic procedures aimed at restoring the space for a detained tooth before starting to bring it to the arch.…”

“…For this reason, they are diagnosed early, which allows for rapid intervention. In the study conducted by Tan [1] among children and adolescents, the incidence of impacted incisors was 2.0%, of which 70.6% of cases concerned the upper medial permanent incisors. Reasons for retention of permanent teeth include lack of space in the arch [2], the presence of supernumerary teeth [2][3][4][5], odontogenic tumor or cyst [2,5], impacted deciduous teeth, tissue scar created as a result of early tooth extraction, trauma to the deciduous anterior teeth [6] and tooth development disorders such as dilacerations [1,2,4].…”

Introduction: Impacted upper central incisors are a big aesthetic, developmental and social problem for patients. One of the causes of tooth eruption is dilaceration, which is the angulation of the tooth root in relation to its crown. The prognosis regarding the possibility of introducing teeth with dilaceration to the dental arch is uncertain and is characterized by a large number of failures. The aim of the study was to conduct a systematic review of the literature discussing the subject of impacted upper central incisors with confirmed dilaceration and illustrate this problem with the presentation of our own clinical case. Objectives: The aim of the study was to conduct a systematic review of the literature discussing the subject of impacted maxillary central incisors with confirmed dilaceration and to illustrate this problem with the presentation of a clinical case. Material and methods: A systematic review of the literature was conducted by searching the medical databases of PubMed and Scopus. The search was carried out by entering the following keywords: dilaceration, impacted tooth, impacted maxillary central incisors. Non-systematic reviews of the literature were excluded from the analysis. Results: The result of searching the databases was a total of 706 articles. Twenty-nine articles corresponding to the objectives of the study were included in the analysis. Among them were original papers, meta-analyses and case reports. The problem of impacted upper central incisors with the diagnosed dilaceration is illustrated by the description of the orthodontic and surgical treatment of the case. Conclusions: Patients with diagnosed impacted tooth with dilaceration require detailed diagnostics to plan orthodontic treatment. The implementation of a comprehensive orthodontic and surgical treatment at an early stage of tooth development gives the best prognosis to introduce a tooth with dilaceration to the dental arch.

Background Supernumerary teeth are those that exceed the usual dental formula. There are different classifications depending on their anatomical location, shape and number. The objective of this study was to determine the prevalence of impacted and supernumerary teeth in a sample of panoramic radiographs from three Latin American countries. Material and Methods A retrospective and cross-sectional study with a quantitative approach, in which the radiographic observation and analysis of 2000 panoramic radiographs, provided by different radiological centers in Peru, Colombia and Bolivia were performed. An examiner, specialized in Stomatology and Oral Surgery, carried out the radiographic analysis to detect the presence of impacted teeth and supernumeraries teeth. All the images were evaluated in a dark room in digital format. The SPSS version 23 package was used for statistical analysis. The Chi-square test was used to determine the association of age, sex, and nationality with the presence of impacted or supernumerary teeth. The level of significance was p < 0.05. Results The prevalence of impacted teeth was 1.7%, with the upper left canine being the most frequent (58.85%). The prevalence of supernumeraries was 3.15% (76 cases), the most frequent being the mesiodens with 1.7% (34), and Peru showing the highest prevalence of mesiodens. No association was found regarding sex. Conclusions The prevalence of impacted teeth evaluated in three recognized radiologic centers from three Latin American countries was low, with the upper left canine being the most frequently impacted tooth. Likewise, the prevalence for supernumerary teeth was also low, with mesiodens having the highest prevalence. Key words: Supernumerary tooth, impacted tooth, panoramic radiograph.
