RESUMO
Objective: To compare the caries experience and the kinds of dental treatment between children with autism spectrum disorders (ASD) and children without systemic disease who were all treated under general anesthesia. Methods: Totally 103 children with ASD who received dental treatments under general anesthesia in 13 professional dental hospitals around China from April to November 2016 were included in the present study. A group of 97 children without systemic disease, according to the age, gender and application propensity score matching method, were chosen as controls, who received dental treatments under general anesthesia between January 2015 to November 2018 in the same hospitals as the children with ASD. Decay missing filling tooth (DMFT/dmft, DMFT for permanent teeth and dmft for primary teeth) indices of two groups of children and the contents of the dental treatments under general anesthesia were analyzed. Results: No significant difference of DMFT/dmft index ï¼»M (Q 25, Q 75)ï¼½ was found between children with ASD group ï¼»0 (0, 3)/11(8, 14)ï¼½ and control group ï¼»0 (0, 3)/9(7, 13)ï¼½ (P>0.05). The average number of dental treatments under general anesthesia and the average number of endodontic treatment in children with ASD were 13 (11, 15) and 3 (2, 6) teeth respectively, while those in the control group were 12 (9, 14) and 2 (1, 4) teeth respectively, the differences were statistically significant (P<0.01, P<0.05). Conclusions: No significant difference was found between children with ASD and the normal controls who receive dental treatments under general anesthesia in DMFT/dmft index, but the treatment needs of children with ASD is relatively higher, and their tooth decay is relatively severer.

OBJECTIVE: To examine the potential mechanisms implicating miR-200c and epithelial-mesenchymal transition (EMT) in oral squamous carcinoma (OSC). MATERIALS AND METHODS: 32 pairs of OSC tissue samples and matched para-carcinoma normal tissue from patients undergoing routine surgery in the Xuzhou Stomatological Hospital from 2014-2016. HOC313 cells were cultured and transfected with miR-200c mimics and scrambled mimics. Cell migration, invasion assays, Luciferase reporter assay, and Western blot assay were conducted. RESULTS: miR-200c was downregulated in OSC tissues compared with adjacent normal tissues (n=32). miR-200c knockdown in the human oral cancer cell line HOC313 significantly suppressed cell invasion and migration, indicating the ability to inhibit tumor progression. Luciferase reporter assay indicated that miR-200c directly bound to the 3'-untranslated regions (3'-UTR) of Zinc finger E-box-binding homeobox (ZEB1) directly. Moreover, miR-200c significantly inhibited HOC313 cell EMT via negatively regulating ZEB1 protein expression. CONCLUSIONS: MiR-200c plays a pivotal role in controlling OSC metastasis via inhibiting EMT, which provides potential therapeutic targets for OSC.
