Resumo: | The cementum is disposed on the dental root surface and presents continuous deposition under physiological condition with different responses to periodontal and occlusal changes, widely used for forensic purposes. The Optical Coherence Tomography (OCT), is a non-invasive, nonionizing method, with the possibility of in vivo and in vitro application. Objective: to quantify and qualify the structure of the cementum through OCT according to dental group, faces, and age group, in addition the correlation between age and cementum thickness was also analyzed. Method: 53 teeth were scanned using the Callisto OCT model (ThorlabsInc, New Jersey, USA), using a superluminescent diode (930 nm) bandwidth of 100 nm and maximum output power of 3 mW. The image analysis were performed using the ImageJ software and the data were analyzed using the IBM SPSS Statistics program (Version 20.0, IBM SPPS). Comparisons of cement thickness and qualitative variables between unrelated groups were performed using the Kruskal Wallis test (p <0,05); Friedman's test (p <0,05) was performed among groups that maintained a link, and Bonferroni's post hoc test when a significant difference was identified. To analyze the correlation between thickness by thirds and age, the Spearmann Correlation Test (p <0,01) was performed. Results: A greater thickness was observed in the thirds in an apical section; with difference in thickness between the dental groups (p <0,05) in the middle and apical thirds (p <0.05); between the faces there was a difference only in the middle third between the buccal and mesial faces (p <0,05); there was an increase in thickness as a result of increasing age with a strong correlation between thickness of the middle thirds (r = 0.712; p <0,01) and apical (r = 0.527; p <0,01) in the anterior dental group. There is a predominance of changes in translucency in the middle and apical thirds, as well as the presence of spots in the apical third regardless of age group, face, and dental groups; as for uniformity, the apical third also showed greater changes in all groups analyzed. Conclusion: Through OCT it was possible to measure the thickness of the cementum, noting also qualitative differences in relation to the thirds and dental group, in addition to differentiation in related age with a greater correlation of age in anterior teeth. |

Partindo da importância da análise do cemento, tem-se a Tomografia por Coerência Óptica (OCT), que corresponde a um método não invasivo, não ionizante, com possibilidade de aplicação in vivo e in vitro. Objetivo: quantificar e qualificar a estrutura do cemento por meio da OCT nos terços radiculares de acordo com grupo dentário, faces, e grupo etário, além de analisar correlação entre idade e espessura do cemento. Método: Foram escaneados 53 dentes por meio da OCT modelo Callisto (ThorlabsInc, Nova Jersey, EUA), utilizando como fonte de luz um diodo superluminescente (930 nm) largura de banda de 100 nm e potência máxima de saída de 3 mW. As análises das imagens foram realizadas através do software ImageJ e os dados foram analisados no programa IBM SPSS Statistics (Versão 20.0, IBM SPPS). As comparações da espessura do cemento e das variáveis qualitativas entre grupos sem vinculação foram realizadas através do teste Kruskal Wallis (p < 0,05); entre os grupos que guardavam vinculação foi realizado o Teste de Friedman (p < 0,05), e post hoc de Bonferroni quando identificada diferença significativa. Para análise de correlação entre espessura por terços e idade, foi realizado o Teste de Correlação de Spearmann (p < 0,01). Resultados: Foi observada maior espessura no terço apical; com diferença na espessura entre os grupos dentários (p<0,05) no terço médio e apical (p<0,05); entre as faces houve diferença apenas no terço médio entre faces vestibular e mesial (p<0,05); observou-se aumento da espessura em função do aumento da idade com correlação forte entre espessura do terços médio (r=0,712; p < 0,01) e apical (r=0,527; p < 0,01) no grupo dentário anterior. Há predominância de alterações na translucidez nos terços médio e apical, bem como de presença de manchas no terço apical independente do grupo etário, face, e grupos dentários; quanto a uniformidade, o terço apical também mostrou maiores alterações em todos os grupos analisados. Conclusão: Por meio da OCT foi possível mensurar a espessura do cemento, constatando diferenciações também qualitativas em relação aos terços e grupo dentário, além de diferenciação com relação a idade, com maior correlação da idade em dentes anteriores.Submitted by Jean Medeiros (jeanletras@uepb.edu.br) on 2022-07-05T17:05:58Z No. of bitstreams: 1 DS - Lígia Natália Sobreira Duarte Bezerra.pdf: 1815723 bytes, checksum: 30e12b18d145ac5769561f2550fc6fad (MD5)Approved for entry into archive by Jean Medeiros (jeanletras@uepb.edu.br) on 2022-09-26T11:59:57Z (GMT) No. of bitstreams: 1 DS - Lígia Natália Sobreira Duarte Bezerra.pdf: 1815723 bytes, checksum: 30e12b18d145ac5769561f2550fc6fad (MD5)Made available in DSpace on 2022-11-01T21:31:24Z (GMT).
