Abstract:As duas pinturas de Rembrandt van Rijn (1606-1669) nas quais o artista holandês retrata lições de anatomia em 1632 e 1656 revelam limitações que a leitura de uma obra de arte pode impor ao olhar contemporâneo se nos ativermos apenas ao universo de nossa subjetividade, ignorando o panorama histórico no qual tais representações foram criadas. A partir dessa constatação aparentemente óbvia, o presente trabalho pretende apontar os parâmetros clássicos que determinaram a longa tradição das práticas anatômicas e alg… Show more
“…Canines are the longest human teeth, 2,13 with an aspect of strength and robustness; 4 its cups tips exceed the occlusal plane of the other teeth. In the present study, the mean total length of the MC was 27.1 mm compared to 24.4 mm for the LC.…”

“…LC presents calcification at 4 to 7 months; its eruption occurs around 9 to 10 years, and calcification ends at 10 to 13 years. 13 According to Della Serra & Ferreira, 3 the total length of the MC varies from 26.8 mm to 32.0 mm; root length ranges from 16.0 mm to 20.0 mm; crown length ranges from 9.39 mm to 12.0 mm; the mesiodistal distance varies from 7.6 mm to 9.0 mm and the buccolingual distance from the crown varies from 8 mm to 9.0 mm. These data is similar to our results, with some variations, mainly related to the measurements of the buccolingual distance.…”

“…The middle lobe is the largest one, corresponding to the position of the cusp tip; distal and mesial lobes are smaller and end at cusp ridges. 2,3,4,13 On MC, the mesial slope of the cusp is shorter than the distal one, with an average length of 4.04 mm (Table 1), which makes possible to differentiate the proximal surfaces, but after tooth wear there may be an inversion of disposition. 3,13 The buccal surface of the LC is similar to the MC, but LC has a more elongated aspect with a larger cervicoincisal dimension, and a smaller mesiodistal distance.…”
Objectives: Permanent canines have an important functional role during mastication due to their anatomy,cbesides its relevance in oral esthetics. However, dentistry undergraduates have great difficulty in differentiating them during dental anatomy classes. The objective of this work was to study the morphology of the extracted permanent maxillary canines (MC) and lower canine (LC) in order to describe the anatomical similarities and differences.Methods: One hundred maxillary canines and 100 lower canines were evaluated. Measurements were performed using a digital caliper, and also visual analysis. The data obtained in each evaluation were submitted to descriptive statistical analysis, and the chi-square test and Fisher's exact test with a significance level of 5% were applied.Results: It was observed that the MC root groove was present on the two proximal surfaces and the groove depth was greater on the mesial surface, as reported in the literature. The MC incisal ridge was normally worn, and imprecision in dental differentiation could occur during the anatomical study, while it is stated that the incisal ridge allows distinguishing this tooth by a simple visual examination. The marginal ridges of the MC had a moderate prominence, as observed in the literature. The MC cingulum often presented a moderate prominence, contradicting some studies which reported a large cingulum. The presence of the cervicoincisal ridge on the lingual surface was frequently observed with moderate, absent or little prominence, while some authors reported that this structure is quite evident. Furthermore, it is reported that MC usually presents aforamen cecum, which was not observed in our sample. LC often presented a worn incisal ridge. The cingulum, marginal ridges, lingual fossa and developmental grooves were less evident and, in some cases, the lingual surface presented a flat shape, which is not usually reported in the literature.Conclusions: The morphological differences and similarities of MC and LC are important for a detailed anatomical study to help dentistry undergraduates identify them correctly. Furthermore, the anatomical study is important for the restorative area for an appropriate aesthetics and function rehabilitation.

“…A anatomia volta a ter relevância com a ascensão do renascimento na Itália no século XV, quando foi estudada por artistas e reformulada por André Vesalius que focou no ensino acadêmico da anatomia e permitiu Dissecação e a percepção de estudantes de medicina sobre a importância da anatomia comparada na integração básico-clínica e do ensino e extensão que essa disciplina fosse valorizada e tivesse a devida importância para a formação de profissionais médicos (UNISC, s/d; Coelho, 2020).…”
A anatomia é considerada um dos conteúdos mais importantes na formação médica, imprescindível para compreender a fisiologia do corpo e a fisiopatologia das doenças. Sendo assim, a anatomia comparada, por meio de dissecação de órgãos de animais é essencial para desenvolvimento do raciocínio clínico. Esse trabalho relata um evento de dissecação, realizado por de uma liga acadêmica do curso de medicina, para o estudo comparativo anatômico. Os estudantes foram divididos em grupos que tiveram e não tiveram anatomia topográfica do tórax e após a dissecação foram submetidos a um questionário e 100% dos alunos relataram que a dissecação do coração contribui para um maior entendimento e que a prática de dissecação, mesmo por meio da anatomia comparada, auxilia na compreensão das estruturas e da fisiologia cardíaca. Essa forma de ensino diminui as lacunas de aprendizado que ocorrem devido a desassociação teórico-prática da disciplina e falta de peças humanas no acervo das universidades.
