An Online Cross-Sectional Survey on Oral Healthcare Among School-Age Children During COVID-19 Epidemic in Wuhan, China.

Since the outbreak of Coronavirus disease 2019 (COVID-19), the government of China adopted many measures which changed people's lifestyle including oral health-related lifestyle to control the transmission. The aim of this study was to investigate oral health status, oral healthcare behaviors, and parental attitudes toward oral healthcare among school-age children in Wuhan during the COVID-19 outbreak and what the status would be when the outbreak is under control. This study was an online cross-sectional survey facing elementary school students in Wuhan.

Impact of COVID-19 on the oral health of adults in Wuhan and China: results of a nationwide online cross-sectional questionnaire survey.

Background: COVID-19 has seriously threatened the health and lives of people. This study aimed to investigate the impact of COVID-19 on the oral health of adults in Wuhan and other places of China amid the epidemic and to evaluate attitudes towards dental care in the post-epidemic period.

Methods: An online cross-sectional survey based on a questionnaire of 22 questions was conducted.

The impact of coronavirus lockdown on oral healthcare and its associated issues of pre-schoolers in China: an online cross-sectional survey.

Background: The sudden outbreak of coronavirus disease (COVID-19) epidemic influenced people's daily life. During lockdown of Wuhan city, the oral health and its associated issues of preschool children were investigated and guidance for dental clinics when the epidemic were controlled in the future were also provided.

Methods: A national online survey was conducted among preschool children and completed by their caregivers.

Long intergenic non-coding RNA 668 regulates VEGFA signaling through inhibition of miR-297 in oral squamous cell carcinoma.

Recently, long noncoding RNAs (lncRNAs) have been reported to have crucial regulatory efficiency in human cancer biology. Long intergenic non-coding RNA 668 (LINC00668) was regarded as an oncogene in multiple cancers. However, the underlying molecular mechanism of LINC00668 in oral squamous cell carcinoma (OSCC) has not been studied.

Long non-coding RNA FTH1P3 facilitates oral squamous cell carcinoma progression by acting as a molecular sponge of miR-224-5p to modulate fizzled 5 expression.

A growing body of evidence has indicated that long non-coding RNAs (lncRNAs) function as competing endogenous RNAs (ceRNAs) during tumorigenesis. In this study, the qRT-PCR results revealed that the lncRNA ferritin heavy chain 1 pseudogene 3 (FTH1P3) was over-expressed in oral squamous cell carcinoma (OSCC) and decreased the survival rate of OSCC patients. Ectopic expression of FTH1P3 facilitates cell proliferation and colony formation in OSCC cells.

Ultrastructural analysis of the teeth affected by amelogenesis imperfecta resulting from FAM83H mutations and review of the literature.

Objective: To analyze the ultrastructure and chemical compositions of two teeth affected by amelogenesis imperfecta (AI) with specific FAM83H mutations.

Study Design: Mutation analysis was performed by sequencing the candidate FAM83H gene. Two extracted teeth were collected: one from a new family and the other from a previously reported family with FAM83H mutation (Q452X).

Comparison of cleaning efficiency and deformation characteristics of Twisted File and ProTaper rotary instruments.

Objective: The objective of the following study is to compare the cleaning efficiency and deformation characteristics of Twisted File (TF) and ProTaper (PT) nickel-titanium rotary instruments in root canal preparation.

Materials And Methods: A total of 52 canals from 26 extracted maxillary first molars were randomly assigned into two groups of each including 13 mesiobuccal and 12 distobuccal (DB) canals. Two DB canals were as blank controls.

Novel RUNX2 frameshift mutations in Chinese patients with cleidocranial dysplasia.

Cleidocranial dysplasia (CCD) is a skeletal disorder caused by heterozygous mutations in the runt-related transcription factor 2 (RUNX2) gene. We evaluated the phenotypes of eight Chinese patients with CCD from three unrelated families followed by analysis of the RUNX2 genes. Three different RUNX2 frameshift mutations were identified.
