简要总结

AIM:

The study aims to assess the histochemical effects due to microplastics released in

saliva of patients undergoing clear aligner therapy.

OBJECTIVES:

  1. To assess the presence of microplastics in saliva of patients undergoing clear

aligner therapy

  1. To analyze the histochemical changes i.e. cytotoxicity, estrogenicity and oxidative

stress caused by these microplastics

The saliva sample will be subjected to the following tests:

a) Fourier Transform Infrared Spectroscopy (FTIR): To assess and characterize the

microplastics present in the saliva sample

b) MTT Assay/ 3-(4,5- dimethylthiazol-2-yl)-2,5-Diphenyl Tetrazolium bromide assay:

To evaluate the cytotoxic effect of the microplastics on primary cultures of human

gingival fibroblasts.

c) MCF-7 cell line test: To assess whether microplastics have estrogenic effects.

d)  MPO Assay: To assess whether microplastics have the potential to cause oxidative

stress.
