Odontologia e osteoporose: uma revisão narrativa / Dentistry and osteoporosis: a narrative review

A osteoporose é caracterizada pela perda óssea e pelo comprometimento da resistência do osso. Essa patologia afeta, também, os ossos da face e consequentemente interfere na atuação dos profissionais da odontologia. Assim sendo, o presente trabalho revisou a literatura acerca da relação entre osteoporose e odontologia. O levantamento dos dados se deu por consulta a livros e nas bases de dados Biblioteca Virtual em Saúde (BVS), PubMed e Scientific Eletronic Library Online (SciELO) e como Descritores em Ciência da Saúde (Decs) foram adotados os termos: "Odontologia", "Osteoporose" e "Saúde bucal". A osteoporose diminui a massa e aumenta a porosidade óssea na maxila e na mandíbula, podendo provocar até quatro vezes mais perda dentária. Os bifosfonatos, principal classe medicamentosa utilizada para o tratamento de osteoporose, estão associados à ocorrência de osteonecrose dos maxilares e ao aumento de tempo de tratamento ortodôntico. Assim, pode-se concluir que é imprescindível o conhecimento do cirurgião-dentista acerca da osteoporose para uma segura abordagem e execução de tratamento.

Osteoporosis is characterized by bone loss and compromised bone strength. This pathology also affects the bones of the face and consequently interferes with the work of dentists. Therefore, the present study reviewed the literature about the relationship between osteoporosis and dentistry. Data collection was carried out by consulting books and the databases Biblioteca Virtual em Saúde (BVS), PubMed and Scientific Electronic Library Online (SciELO) and as Medical Subjects Headings (MeSH) the terms adopted were: "Dentistry", "Osteoporosis" and "Oral health". Osteoporosis reduces bone mass and increases bone porosity in the maxilla and jaw, which can cause up to four times more tooth loss. Bisphosphonates, the main class of medications used to treat osteoporosis, are associated with the occurrence of osteonecrosis of the jaw (ONJ) and increase the time of orthodontic treatment. Thus, it can be concluded that the dentist's knowledge of osteoporosis is necessary for a safe approach and execution of treatment.

Radicular cyst in primary dentition showing angiolymphoid hyperplasia with eosinophilia (ALHE)-like features: An immunohistochemical study

The microscopical diagnosis of radicular cyst (RC) is straightforward; nonetheless, in some cases with unusual histopathological features, strict clinicopathological correlation is necessary to achieve the correct diagnosis. We report a case of a 5-year-old girl was referred presenting extensive carious lesion in the tooth #55, associated with vestibular sinus tract. Medical history revealed allergic asthma diagnosis. After clinical and imagi-nological exams, the deciduous tooth was extracted. Microscopically, the soft tissue lesion attached to the root showed typical RC features; however, in the cystic capsule, lymphoid follicles and vascular networks (lined by epithelioid endothelial cells) surrounded by nu-merous eosinophils, were observed. Immunohistochemistry, through CD3, CD20, CD34 and alpha-smooth muscle actin antibodies, highlighted these findings. Moreover, CD1a and CD207 were negative. To the best of our knowledge, this is the first report of RC showing angiolymphoid hyperplasia with eosinophilia (ALHE)-like features. (AU)
