Osteochondroma of the mandibular condyle has been found in the oral and maxillofacial region rarely. This paper describes a case of osteochondroma of the mandibular condyle in a 20-year-old woman, who was referred to our service with facial asymmetry, prognathic deviation of chin, cross-bite to the contralateral side, changes in condylar morphology, limited mouth opening, and malocclusion. Computed tomography (CT) was performed for better evaluation to the pathological conditions on the temporomandibular joint. Based on the clinical examination, patient history, and complementary exams, the hypothesis of osteochondroma was established. Condylectomy was performed using a preauricular approach with total removal of the lesion. After 3 years of postoperative follow up and orthodontic therapy, the patient is symptom-free, and has normal mouth opening with no deviation in the opening pattern.
A erosão dentária é um problema! The dental erosion is a problem! La erosión dental é un problema! Resumo A erosão dentária ou desgaste dentário erosivo é considerado um problema de saúde bucal contemporâneo, causado por processos químicos de "agressões ácidas" ao dente, sem o Research, Society and Development, v. 9, n. 3, e168932723, 2020 (CC BY 4.0) | ISSN 2525-3409 | DOI: http://dx.doi.org/10.33448/rsd-v9i3.2723 2 envolvimento bacteriano, que provoca a perda da sua estrutura mineral. Este problema ocorre em uma condição multifatorial, podendo haver a interação entre os fatores biológicos, químicos e comportamentais. Nos últimos anos a sua prevalência tem aumentado, tornando-a um desafio para os cirurgiões-dentistas, especialmente quando ela alcança estágios mais avançados aonde pode causar dor, hipersensibilidade, problemas com função e estética.Através de uma revisão da literatura, o presente estudo tem como objetivo orientar os cirurgiões-dentistas com informações a respeito da história, etiologia, diagnóstico, prevenção e tratamento do desgaste dentário erosivo. O conhecimento sobre os fatores etiológicos do desgaste dentário erosivo torna-se importante para evitar a progressão deste problema, além de estabelecer medidas preventivas eficazes desde a infância. O cirurgião-dentista deve realizar o diagnóstico precoce e realizar o tratamento adequado deste problema, sendo principalmente as orientações referentes à alimentação e higiene bucal além das terapias com flúor.Palavras-chave: Erosão dentária; Odontopediatria; Desgaste dos dentes. AbstractTooth erosion or erosive tooth wear is considered a contemporary oral health problem, caused by chemical processes of "acid attack" to the tooth, without bacterial involvement, which causes the loss of mineral structure. This problem occurs in a multifactorial condition, and there may be an interaction between biological, chemical and behavioral factors. In recent years, its prevalence has increased, making it a challenge for dentists, especially when it reaches more advanced stages where it can cause pain, hypersensitivity, problems with function and aesthetics. Through a literature review, the present study aims to guide dental surgeons with information about the history, etiology, diagnosis, prevention and treatment of erosive tooth wear. Knowledge about the etiological factors of erosive tooth wear becomes important to prevent the progression of this problem, in addition to establishing effective preventive measures since childhood. The dental surgeon must perform an early diagnosis and perform the appropriate treatment of this problem, mainly the guidelines regarding food and oral hygiene in addition to fluoride therapies.
