Plaque

The clinical study will examine the effects of brushing with randomly assigned test toothpaste on the bacteria on the dental plaque, tongue, cheek, gum surface, and in saliva

The objective of this clinical research study is to collect and analyze plaque and oral health measures in a population with high plaque/low gingivitis and high plaque/high gingivitis

ICECAP is a multi-centre, prospective, single-arm, interventional, traditional feasibility clinical investigation to evaluate the efficacy and safety of intra-coronary cryotherapy on vulnerable or high-risk plaque (HRP), using the CryoTherapy System (CTS). The study aims to enroll 25 patients with symptomatic coronary artery disease, successfully treated for their culprit lesion and with presence of at least one HRP lesion in another vessel. Eligible patients will undergo cryotherapy during a planned procedure. Near-infrared spectrometry (NIRS and Optical Coherence Tomography imaging will be used during baseline procedure, and during a 9 months follow visit. The primary endpoint is reduction of plaque burden measured as 30% reduction in maxLCBI4mm as measured by NIRS at 9 months post procedure.

This study is a six-week, double-blind, randomized, parallel-group controlled clinical study. The objective of this study is to evaluate the changes to the oral microbiome, inflammatory mediators, gingival health indices and to assess oral tolerance after 4 weeks of twice daily use of differing oral hygiene regimens including mouthwash compared to a control group. A follow-up assessment will be completed 2 weeks after cessation of treatments.

This is a clinical study to evaluate the safety and effectiveness of COMORAL®, the intraoral water-spraying cleaning device that is developed to remove plaque around teeth in the oral cavity. To do so, 42 healthy subjects, 21 control and 21 experimental, will be recruited. To establish the baseline, all subjects will receive dental hygiene service. After 2 weeks, patients will be randomly assigned to either control or intervention group (21 individuals each). Both groups will be asked to brush their teeth once a day but without dental floss, mouth rinse, and gum chewing, throughout the 4 weeks of study period. During the study period, the experimental group will receive COMORAL® treatment three times a day every day for 4 weeks except Saturday and Sunday. Subjects will get evaluated for the oral status(PI, BOP, GI, PD, GR, CAL) and the status of periopathogens on visit 1, visit 2 and visit 3.
