Filter by:The primary objective of this exploratory study is to evaluate the efficacy of an Oral Irrigator in the reduction of gingivitis compared to a negative control over a 3 week period by using the Modified Gingival Index and the Gingival Bleeding Index. The secondary objective is to evaluate the efficacy of an Oral Irrigator in the reduction of plaque compared to a negative control using the extended Turesky Modified Quigley-Hein Index (TQHPI) after 3 weeks of use.
The objective of the study is to evaluate the safety and efficacy of the home-use device ToothWave (Model H7001) for calculus reduction and the prevention of calculus accumulation.
Scientists and medical workers all around the world were running out of time to manage COVID-19. Several studies have been done to understand the disease and ultimately to find possible treatment. Based on those studies, one of the potential treatment was antibody transfer from recovered COVID-19 patients. Passive antibody transfer was a fast and easy choice. The rational use of antibody from the patient's plasma is a natural neutralizing protein to the cell-infected virus and could possibly slow the active infection down. Investigators initiate an intervention study with purposes to produce quality convalescent plasma from the recovered patients, define the safety of plasma for human use and as an alternative treatment to improve the clinical outcomes of severe COVID-19 patients. The study hypothesis is convalescent plasma is safe and could possibly improve outcome of severe (non-critical) COVID-19 patients. This research will conduct the plaque reduction neutralizing test (PRNT) of recipient blood in vitro. The plasma will be collected in the blood transfusion unit (BTU) in Gatot Soebroto hospital. The storage, testing, transfer, and transfusion of eligible convalescent plasma are the authority of Gatot Soebroto BTU. PRNT and plasma antibody titer measurement from donor plasma will be conducted at Eijkman Institute of Molecular Biology. Investigators enroll approximately 10 patients consecutively, who will be admitted at Gatot Soebroto hospital. Baseline demographic characteristics of samples are recorded. Clinical dan laboratory data will be measured before and after plasma transfusion periodically. The measured variables are pharmacological therapy (antivirus, antibiotics, steroids), invasive oxygen therapy, oxygen index, sequential organ failure assessment (SOFA) score, and laboratory parameters such as leukocyte count, blood chemical panel include liver and renal function, C-reactive protein, procalcitonin, IL-6 and immunoglobulin titer of the recipient and also chest X-ray evaluation. The potential expected risk of plasma transfusions is transfusion reaction (immunological or non-immune related) and transferred foreign pathogen. Investigator will report and treat all adverse events after plasma transfusion has been done. A severe adverse event (SAE) will also report in a special form to sponsor and data safety monitoring board (DSMB). There is theoretically antibody-dependent enhancement (ADE) mechanism from COVID-19 whom will receive plasma transfusion to progress to severe immune response. This preliminary study is supposed to provide supporting data and experience of plasma processing to a larger study in the near future.
The objective of the study is to evaluate the safety and efficacy of the home-use device Silk'n toothbrush (ToothWave) for the improvement in dental health through the reduction of plaque, gingivitis, and calculus.
This study evaluates the interdental plaque removal efficacy, flossing speed, and reduction in gingival inflammation of a new flossing system (GumChucks®) compared to string floss, and to assess preference between the two flossing products in children, parents, and dentists.
This study objective is to test the Silk'n Toothwave self-selection, by potential end users. Additionally, this study will evaluate if contraindicated subjects will self-exclude from use of the device and the ability to understand accurately the labeling content (box and user manual).
The aim of this analysis was to compare the effects of oscillating-rotating (O-R), side-to-side (sonic), and manual toothbrushes on plaque and gingival health after multiple uses.
This study evaluates the effectiveness of brushing and flossing sequence in the control of dental plaque and gingival inflammation.
Dental caries is a polymicrobial infection originally thought to be caused by Streptococcus mutans and Lactobacilli. However, unprecedented developments in modern molecular techniques have demonstrated that several microbial species are associated with the disease in addition to streptococci and lactobacilli. Dental caries initiation and progression is a dynamic process in which demineralization of the tooth structure, as a result of acid production from acidogenic bacteria (due to carbohydrate metabolism) is being counteracted by the remineralization of the tooth surface by strong alkali production by certain bacteria in the dental biofilm. The aim of the present study is to identify the different microbiota in the oral biofilm using new laboratory techniques as well as the levels of salivary proteins in caries-free compared with caries active Arab children.
