Effects of Sjogren's syndrome and high sugar diet on oral microbiome in patients with rampant caries: a clinical study.

Objective: The purpose of this study was to assess the composition of the oral microbial flora of adults with rampant caries in China to provide guidance for treatment.

Patients And Methods: Sixty human salivary and supragingival plaque samples were collected. They were characterized into four groups: patients with rampant caries with Sjogren's syndrome (RC-SS) or high-sugar diet (RC-HD), common dental caries (DC), and healthy individuals (HP).

A focusing method on refraction topography measurement.

This paper introduces a novel focusing method Refraction Topography (RT) for wide-angle refraction measurement. The agreement of the test results obtained using RT is evaluated against simulation results and expected refraction. RT develops a refraction algorithm on fundus images at various focusing statuses.

Role of Ku70 in the apoptosis of inflamed dental pulp stem cells.

Aim: The study aimed to investigate the effects of DNA repair proteins on cell apoptosis in human DPSCs during inflammation.

Methods: Lipopolysaccharide (LPS) was used to stimulate inflammation in dental pulp in vivo and in vitro. We identified the activation of DSB response and DNA repair proteins in inflamed pulp tissue and in LPS-treated human DPSCs.
