AVALIAÇÃO DA QUALIDADE DA IMAGEM RADIOGRÁFICA INTRAORAL EM PACIENTES QUE FAZEM USO DE PROTETO SOLAR EM REGIÃO DE FACE: ESTUDO IN VITRO

Abstract

Changes in human lifestyle led to increased sun exposure, which ended up raising the use of chemical and physical protection to mitigate the harmful effects of sun rays. Currently, there are two types of sunscreens: organics and inorganics. The inorganic ones contain metallic oxides that act as a physical barrier against ultraviolet (UV) radiation. Considering that the use of dental radiographs for diagnostic and planning purposes has been increasing, the aim of this in vitro study was to evaluate if the use of sunscreen on the facial area can influence the quality of the radiographic image. For this study, high-transparency circular polystyrene plates were used, and a mold was made with high-performance addition silicone. After being placed on the plate, a photostimulable phosphor plate (PSP) was inserted in the center of the mold to ensure standardization during the radiographic acquisitions. Bioderma® facial sunscreens with sun protection factor (SPF) 50 were used: one organic (Photoderm Max) and the other inorganic (Photoderm nude touch). Using a precision balance, the corresponding amounts of facial sunscreens were deposited, and the groups were divided into 1- Control (without facial sunscreen), 2- Organic facial sunscreen and 3- Inorganic facial sunscreen. Five radiographs were taken from each group, under the same exposure parameters. The images were evaluated according to density, uniformity and noise. The results were compared using the two-way analysis of variance statistical test, with Tukey's post-hoc test with a significance level of 5%, and it showed that group 3- Inorganic facial sunscreen presented higher radiographic density average and uniformity than groups 1 and 2, in addition to a significant statistical difference. No significant statistical difference was observed between groups 1 and 2. In relation to noise, the groups did not present significant statistical differences. In conclusion, it was seen that the inorganic facial sunscreen influences the quality of the radiographic image, in relation to radiographic density, uniformity and noise.
