Resumo: | Carious lesion is one of the most prevalent diseases in humankind, affecting nearly all human beings at least once in a lifetime. Early carious lesion (ECL, also known as white spot lesion) is part of the caries process in which the enamel surface loses mineral but the subsurface layer overlying the mineral-poor region remains intact. In its early stages, the detection of the carious lesion is currently still a major challenge because it is based on visual inspection, thus with an inherent subjectivity. In this work, we present a method to detect and assess the severity of ECLs using a computer-assisted laser speckle imaging technique. Forty-five polished and cut bovine incisors samples allow a paired t-test by exposing half of the surface while protecting the other half. The samples, included in a PVC tube, were immersed in 50ml of a solution (pH 5.0) containing 0.05M acetate buffer solution and 50% saturated hydroxyapatite enamel powder at 37°C. The etching time is 24h; 48h and 72h; each group contain 15 samples. We illuminate each sample with a laser and analyse the first momentum of the laser speckle images with a computer. Our results shows that the first momentum of the LSI of the sound region statistically differs from the decay region of the samples for all groups (p<0.0001). We also found a strong correlation between the acid etch duration (severity of the decay) and the shift in LSI contrast (Pearson’s correlation coefficient ρ=0.9989, R²=0.9978). Detecting decay in its early stages is still a challenge in the clinical practice, however this work demonstrates that the analysis of the statistical features of the laser speckle image in the spatial domain allows for the detection of microstructural changes in the enamel associated with the presence of the lesion even before any intervention is required. |

La lesión cariosa temprana (ECL, también conocida como lesión de mancha blanca) es parte del proceso de caries en el que la superficie del esmalte pierde mineral, pero la capa subsuperficial que cubre la región pobre en minerales permanece intacta. En sus etapas iniciales, la detección de la lesión cariosa sigue siendo un gran desafío en la actualidad porque se basa en la inspección visual, por lo que tiene una subjetividad inherente. En este trabajo, presentamos un método para detectar y evaluar la gravedad de las ECL utilizando una técnica de imagen de moteado láser asistida por computadora. Cuarenta y cinco muestras de incisivos bovinos pulidos y cortados permiten una prueba t emparejada al exponer la mitad de la superficie mientras se protege la otra mitad. Las muestras, incluidas en un tubo de PVC, se sumergieron en 50 ml de una solución (pH 5,0) que contenía una solución tampón de acetato 0,05 M y polvo de esmalte de hidroxiapatita saturada al 50% a 37ºC. El tiempo de grabado es de 24 h; 48h y 72h; cada grupo contiene 15 muestras. Iluminamos cada muestra con un láser y analizamos el primer impulso de las imágenes de motas láser con una computadora. Nuestros resultados muestran que el primer impulso del LSI de la región de sonido difiere estadísticamente de la región de decaimiento de las muestras para todos los grupos (p <0,0001). También encontramos una fuerte correlación entre la duración del grabado ácido (severidad de la descomposición) y el cambio en el contraste LSI (coeficiente de correlación de Pearson ρ = 0.9989, R² = 0.9978). La detección de la caries en sus primeras etapas sigue siendo un desafío en la práctica clínica, sin embargo, este trabajo demuestra que el análisis de las características estadísticas de la imagen de moteado láser en el dominio espacial permite la detección de cambios microestructurales en el esmalte asociados con la presencia de la lesión incluso antes de que se requiera cualquier intervención.A lesão de cárie é uma das doenças mais prevalentes na humanidade, afetando quase todos os seres humanos pelo menos uma vez na vida. A lesão de cárie precoce (ECL, também conhecida como lesão de mancha branca) é parte do processo de cárie no qual a superfície do esmalte perde mineral, mas a camada subsuperficial que recobre a região pobre em minerais permanece intacta. Em seus estágios iniciais, a detecção da lesão cariosa ainda hoje é um grande desafio, pois é baseada na inspeção visual, portanto, com uma subjetividade inerente. Neste trabalho, apresentamos um método para detectar e avaliar a gravidade de lesão de carie usando uma técnica de imagem por laser speckle assistida por computador. Quarenta e cinco amostras de incisivos bovinos polidos e cortados permitem um teste t pareado, expondo metade da superfície e protegendo a outra metade. As amostras, incluídas em tubo de PVC, foram imersas em 50ml de uma solução (pH 5,0) contendo solução tampão acetato 0,05M e pó de esmalte com hidroxiapatita saturada 50% a 37 ° C. O tempo de corrosão é de 24h; 48h e 72h; cada grupo contém 15 amostras. Iluminamos cada amostra com um laser e analisamos o primeiro momento das imagens do laser speckle com um computador. Nossos resultados mostram que o primeiro momento do LSI da região do som difere estatisticamente da região de decaimento das amostras para todos os grupos (p <0,0001). Também encontramos uma forte correlação entre a duração da corrosão ácida (gravidade da deterioração) e a mudança no contraste LSI (coeficiente de correlação de Pearson ρ = 0,9989, R² = 0,9978). Detectar cáries em seus estágios iniciais ainda é um desafio na prática clínica, porém este trabalho demonstra que a análise das características estatísticas da imagem speckle a laser no domínio espacial permite a detecção de alterações microestruturais no esmalte associadas à presença de a lesão antes mesmo de qualquer intervenção ser necessária.Research, Society and Development2020-12-20info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1103910.33448/rsd-v9i12.11039Research, Society and Development; Vol. 9 No. 12; e22491211039Research, Society and Development; Vol. 9 Núm. 12; e22491211039Research, Society and Development; v. 9 n. 12; e224912110392525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/11039/9855Copyright (c) 2020 João Vagner Pereira da Silva; Ravana Angelini Sfalcin; Vola Masoandro Andrianarijaona; Luciano Gillieron Gavinho; Luciana Toledo Costa Salviatto; Sandra Kalil Bussadori; Alessandro Melo Deanahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSilva, João Vagner Pereira daSfalcin, Ravana AngeliniAndrianarijaona, Vola Masoandro Gavinho, Luciano Gillieron Salviatto, Luciana Toledo Costa Bussadori, Sandra Kalil Deana, Alessandro Melo 2020-12-30T23:32:22Zoai:ojs.pkp.sfu.ca:article/11039Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:32:58.305884Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |

In this work, we present a method to detect and assess the severity of ECLs using a computer-assisted laser speckle imaging technique. Forty-five polished and cut bovine incisors samples allow a paired t-test by exposing half of the surface while protecting the other half. The samples, included in a PVC tube, were immersed in 50ml of a solution (pH 5.0) containing 0.05M acetate buffer solution and 50% saturated hydroxyapatite enamel powder at 37°C. The etching time is 24h; 48h and 72h; each group contain 15 samples. We illuminate each sample with a laser and analyse the first momentum of the laser speckle images with a computer. Our results shows that the first momentum of the LSI of the sound region statistically differs from the decay region of the samples for all groups (p<0.0001). We also found a strong correlation between the acid etch duration (severity of the decay) and the shift in LSI contrast (Pearson’s correlation coefficient ρ=0.9989, R²=0.9978).
