“…In all the studies, the caries lesion was arrested in 100% of the sealed teeth. Except in a study that presented 64.3% success rate in sealed lesions with glass ionomer sealant and 85.7% in lesions sealed with resin sealant [19]. In the present study the non-removal of the carious tissue did not present differences when compared to teeth restored with healthy dentin in relation to the infiltration of the methylene blue dye.…”

“…The quantitative evaluation, carried out by means of a comparison between the coefficients of demographic density, showed an increase of the density coefficients in Gres and in the Gciv a stability of the coefficients. Thus, it can be concluded that, under the conditions of this study, the use of pit and fissure sealants was effective in the treatment of carious lesions [19].…”

Objective: To evaluate the sealing of cavities of dentinal occlusal caries lesions, reproduced in vitro, with flow resin compared to cavity restorations presenting healthy dentin using microhybrid composite resin. Methods: The sample consisted of 27 healthy deciduous molars where cavities of approximately 2 mm in the fossa region were performed and occlusal cleft of each tooth were sealed, impermeabilization was performed and the sample was randomly divided into 2 groups: group I underwent cariogenic challenge and occlusal sealing with resin flow. The teeth of group II were restored with microhybrid composite resin. The teeth were immersed in 5% methylene blue for 8 hours at 37° C and washed until all the dye was removed from the surface. The teeth were sectioned in the mesio-distal direction. The penetration of the dye was evaluated: 0- no penetration; 1- dye penetration up to 1/3 of the restoration; 2- dye penetration up to 2/3 of the restoration depth; 3 - penetration of dye into the pulp wall. The results were analyzed by the Biostat 4.0 program. Descriptive analysis and the mode among the examiners submitted to the Mann-Whitney test. Results: There was no significant difference in microleakage between restoration performed in healthy dentin with microhybrid composite resin or maintenance of infected dentin in primary teeth sealed with resin flow (p = 0.6035). Conclusion: It was concluded that the marginal infiltration of primary molars sealed with microhybrid composite resin and resin flow was not influenced by the removal -or not -of the carious tissue or the material used.

“…Radiographs were taken with a standardized angle of incidence of the X-ray beam and at a standardized distance between the appliance and the tooth film, which was determined using an acrylic resin bite guide. 6 Therefore, the radiographs could be repeated with the same distance from the film source (40 cm) and the same vertical and horizontal angulations. Two types of radiographic films and the same X-ray device were used for each patient.…”

| Objective: This study aimed to investigate how the radiographic processing method affect the radiographic density of two types of film. Methods: Radiographs from non-cavitated occlusal caries lesions obtained in a previous study were used. We analyzed 28 films from 12 patients that were obtained with the same X-ray device. Seven Ektaspeed (Kodak Eastman Kodak Co, Rochester, NY, USA) and seven Ultraspeed (Kodak Eastman Kodak Co) films were manually processed, while seven Ektaspeed and seven Ultraspeed films were automatically processed. The angle of incidence of the X-ray beam and the distances between the apparatus, the tooth and the film were standardized. Therefore, the study comprised four groups: GE1: Ektaspeed manually processed; GE2: Ektaspeed automatically processed; GU1: Ultraspeed manually processed; and GU2: Ultraspeed automatically processed. The images were digitized (G40450 Scan Jet C/T, Hewlett-Packard) and analyzed using Digora for Windows 2.7 (Soredex Medical Systems) to obtain the average radiographic density, and data were analyzed using Student's t test for paired data (Bioestat 5.3). Result: Only the Ektaspeed film showed statistically significant differences among radiographic densities with different processing methods (p = 0.0037). Conclusion: The Ektaspeed film automatically processed is better suited for the early diagnosis of caries lesions.DESCRIPTORS | X-Ray Diagnosis; Dental Caries; Digital Dental Radiography; Community Dentistry. RESUMO | Influência do tipo de filme e método de processamento na densidade radiográfica para diagnóstico de cárie oclusal •Objetivo: Este estudo tem como objetivo estudar a influência do método de processamento na densidade radiográfica de dois tipos de filmes. Métodos: Foram utilizadas radiografias de lesões de cárie oclusais não cavitadas obtidas em estudo prévio. Foram analisados 28 filmes obtidos de 12 pacientes cujas radiografias foram realizadas com o mesmo aparelho radiológico. O mesmo número de filmes (n=7) Ektaspeed (Kodak Eastman Kodak Co, Rochester, NY, USA) e Ultraspeed (Kodak Eastman Kodak Co) foram processados manualmente e automaticamente. Desta forma, o estudo compreendeu quatro grupos: GE1: Ektaspeed processado manualmente (n=7); GE2: Ektaspeed processado automaticamente (n=7); GU1: Ultraspeed processado manualmente (n=7) e GU2: Ultraspeed processado automaticamente (n=7). As imagens foram digitalizadas (G40450 Scan Jet C/T, Hewlett-Packard) e analisadas utilizando o programa Digora for Windows 2.7 (Soredex Medical Systems) para obter a média da densidade radiográfica. Os dados foram analisados através do teste T de Student para dados pareados (Bioestat 5.3). Resultado: Apenas o filme Ektaspeed mostrou diferenças estatisticamente significantes entre as densidades radiográficas com os diferentes métodos de processamento (p = 0.0037). Conclusão: O filme Ektaspeed processado automaticamente é mais apropriado para o diagnóstico precoce de lesões de cárie oclusal. DESCRITORES |
