“…However, they may result in headache, crowding, diastema, late or ectopic eruption, expulsion of teeth into the floor of the nasal cavity, loss of adjacent teeth, and worsening of existing conditions [4]. Incisors, canines, and premolars have all been reported to have inverted impactions [5][6][7]. Molars were seldom noted as a source of discomfort or impaction.…”

Even while certain forms of mandibular impactions (such as inverted molars) might be considered unusual findings, mandibular impacted teeth are really one of the most regularly seen dental abnormalities. Two female patients' mandibular third molars were discovered to be inverted during a regular inspection, and two such examples are reported here in this article. Both patients underwent routine radiographic examination. Cone beam computed tomography and orthopantomogram were requested to evaluate the state of the bone and to check for any abnormalities, and inverted impacted teeth were discovered. A tooth is said to be inversed when it is placed reversed and seated upside down. Ascending ramus is the most common site for third molars in the mandible. It is also possible for a maxillary tooth to get impacted and for the tooth to be pushed all the way to the orbit's floor, though mandibular impacted teeth are more common. Only a few cases of inverted and impacted mandibular third molars have been reported in the literature. No definitive treatment protocols exist for the removal of inverted teeth. The safest protocol is conservative treatment in which the teeth are not extracted until they produce pathological signs.

“…A inversão de dentes é uma variação rara, quando acontece é especialmente observada nos terceiros molares (ABU-MOSTAFA et al, 2015;SOL et al, 2019;AGARWAL et al, 2019;OLIVEIRA et al, 2018;DĄBROWSKI et al, 2019) e em dentes supranumerários (STRINGHINI JUNIOR et al, 2015;Ogane et al, 2017;JONES et al, 2019;RESENDE et al, 2020). Ainda menos frequente é o relato de caninos invertidos.…”

Objetiva-se relatar e descrever um caso de impactação e inversão de caninos superiores permanentes, discutindo-se o seu valor para o processo de identificação humana. A pesquisa foi realizada com esqueleto pertencente à Coleção de Esqueletos Identificados do Centro de Estudos em Antropologia Forense (CEAF) da Faculdade de Odontologia da Universidade de Pernambuco (FOP/UPE). Inicialmente, o esqueleto foi montado em posição anatômica e posteriormente procedeu-se à descrição dos ossos presentes e das alterações observadas, bem como às fotografias da ossada. O esqueleto pertencia a indivíduo do sexo feminino, com 82 anos de idade à morte e apresentou, ao exame macroscópico, a impactação e total inversão de ambos os caninos permanentes superiores. Os referidos dentes apresentavam-se localizados lateralmente e no terço médio da crista zigomático-alveolar da maxila, em posição verticalmente invertida (com as coroas voltadas para as bases das órbitas e raízes voltadas para os rebordos alveolares). Essa variação apresenta uma baixa frequência de ocorrência na população e, assim como todas as outras anomalias, funcionam como fatores individualizantes, tornando os indivíduos ainda mais únicos. Quando apropriadamente registradas em prontuário odontológico, servem como excelentes fontes de dados ante mortem, no processo de identificação humana, a partir do confronto com as informações post mortem coletados nos exames necroscópicos. Por isso, é importante que, cada vez mais, os Cirurgiões-dentistas adquiram a consciência do valor dos prontuários clínicos e cumpram com o dever de elaborá-lo e mantê-lo atualizado, explicitamente expresso no Código de Ética Odontológica.

“…In terms of angulation, vertical impaction is counted 63% of the time, while distoangular and mesioangular impactions are counted 25% and 12% of the time, respectively. Some rare positions, such as inverted, transverse, and horizontal, are present in less than 1% of cases [ 1 , 2 ].…”

“…Class B impaction implicates an impacted tooth with an occlusal plane between the occlusal and cervical lines of the adjacent molar. Class C impaction occurs when the occlusal plane of the impacted tooth is lower than the cervical line of the adjacent molar [ 2 ].…”

Patient: Male, 48-year-old Final Diagnosis: Inverted impaction within the maxillary sinus Symptoms: Asymptomatic Clinical Procedure: — Specialty: Dentistry Objective: Unusual clinical course Background: The maxillary third molar is considered one of the most impacted teeth and can present in different types based on the direction and depth of the impaction. However, the inverted type of maxillary third molar impaction is a rare condition, with few reported cases in the current literature. Case Report: We report an extremely rare case of a 48-year-old man with an inverted maxillary third molar situated in the maxillary sinus in direct contact with the posterior wall of the sinus, with a portion of the coronal part perforating the infratemporal fossa. Because of the anatomical and structural complexity of the impaction and because the tooth has never been symptomatic, the case was conservatively managed after weighing the risks and benefits of surgical intervention. A 2-year follow-up was made to ensure no changes in the impaction location, confirming the validity of the conservative approach. Conclusions: This case is the first reported inverted maxillary third molar impacted in such an anatomical location. This reported case contributes to existing knowledge regarding this rare type of impaction and that this rare impaction location can present congenitally with a non-iatrogenic origin. A thorough dental history and clinical and radiographical examinations will aid dental professionals in their clinical decision making for patients with similar presentations.
