Scientific production of Brazilian researchers focusing on oral surgery, oral medicine, and oral pathology

Abstract We analyzed the distribution characteristics of the scientific production of Brazilian dentistry researchers of the Brazilian National Council for Scientific and Technological Development. The Lattes curriculum data of 211 researchers from Oral Pathology, Oral Surgery, and Oral Medicine fields were included (2018-2020). Over their academic career, 39 researchers published 7,555 papers (average, 175 articles/researcher); 3,876/7,555 papers were indexed in the Web of Science. During 2018-2020, 1,440/7,555 (19%) papers were published. Brazilian dental researchers contribute significantly to international research by participating in scientific journals' editorial boards, evaluating research promotion agencies, training researchers, and contributing to scientific and technological development.

Unusual nodular lesion of the tongue: clinical report of chondroid metaplasia / Lesão incomum de língua: relato clínico de metaplasia condoide

OBJETIVOS: Revisar os conceitos de metaplasia condroide e relatar um caso incomum desta rara condição que se apresentou como uma massa nodular na borda lateral da língua em um paciente adolescente. DISCUSSÃO E CONCLUSÃO: Metaplasia é a conversão, na vida pós-natal, de um tipo de célula para outra. Pode ser causada por algum estímulo anormal. A origem de cartilagem em tecidos moles bucais é desconhecida, mas várias hipóteses foram postuladas. Embora a etiopatogênese seja incerta, sugeriu-se que a metaplasia condroide ocorre como uma reação defensiva e originada de células mesenquimais miltipotentes. A metaplasia condroide é uma alteração benigna que ocorre como resposta à irritação crônica física ou química. A diferenciação entre coristoma cartilaginoso e metaplasia condroide pode ser difícil e, muitas vezes, uma questão de conceito. Considerando os achados do presente caso, a condição foi diagnosticada como metaplasia condroide de língua.

OBJECTIVES: To review the concepts of chondroid metaplasia and to report an unusual case of this rare condition, presenting as a nodular soft tissue mass in the lateral border of the tongue in an adolescent. DISCUSSION AND CONCLUSION: Metaplasia means the conversion, in postnatal life, of one cell type to another. It could be caused by some abnormal stimuli. The origin of cartilage in the oral soft tissues is unknown but several hypotheses have been postulated. Although the etiopathogenesis is unclear, it has been suggested that chondroid metaplasia may occur as a defensive reaction and it is originated from multipotential mesenchymal cells. Chondroid metaplasia is a benign change that occurs as a response to chronic physical or chemical irritation. The differentiation between cartilaginous choristoma and chondroid metaplasia could be very difficult and sometimes a matter of concept. Considering the findings of the current case, the lesion was diagnosed as chondroid metaplasia of the tongue.
