Bad Breath Response to Tongue Scraper and Rinses
Medical center personnel are screened organoleptically for bad breath by 2 investigators using Rosenberg scale 0-5, and measurement of breath sample in gas chromatograph. With a threshold score of 2 or more, or 75ppb H2S, subjects invited to enter clinical trial of the mechanical effect of daily tongue scraping with the adjunctive use of 0.12% chlorhexidine gluconate mouthwash or 0.1% stabilized chlorine dioxide. Subjects randomly assigned in double-blind trial for one week. The null hypothesis is there will be no difference between the two rinses as adjuncts to tongue scraping.
Subjects in trial will have oral and periodontal exam and score the Ramfjord teeth for PlI, GI, PD, recession. A tongue index is scored and sample of coating on dorsum taken for culture of total viable count and % black colonies on anaerobe agar with sulfur added. Subjects given hygiene instruction and instruction on use of scraper, then rinse with 20ml assigned mouthwash 30sec. Breath assessed by organoleptic means and mouth air sample in chromatograph at 0, 1, 2, and 4 hours. Subjects use scraper and mouthwash twice daily for one week and return for final exam.

Previous research has shown the oxidizing properties and microbiological efficacies of chlorine dioxide (ClO2). However, no clinical studies have investigated its microbiological efficacie...
The goal of this clinical research study is to find out if 1% chlorhexidine gluconate gel will decrease the amount of bacteria that causes tooth decay. Whether the gel is acceptable to pat...
This study is to test whether a chlorine dioxide gas-generating device, which releases a low concentration gas of chlorine dioxide in a sustained manner, can protect against respiratory in...

The investigators propose a novel assessment of oral malodor (halitosis) by a quality of life (QOL) questionnaire designed specifically for halitosis and a new treatment for halitosis by i...
The aim of this study is to compare the antiplaque efficacy of green tea catechin mouthwash with chlorhexidine gluconate mouthwash.
Organic tissue dissolution is an important property of an irrigant which aids in the success of root canal treatment. Recent studies have advocated the use of Chlorine dioxide as an endodontic irrigan...
Purpose: The present study was conducted to assess the effectiveness of Terminalia chebula on plaque and gingival inflammation and compare it with the gold standard chlorhexidine (CHX 0.2%) and distil...
The aim of this study was to assess the influence of temperature and concentration on the dynamic viscosity of sodium hypochlorite in comparison with 17% EDTA and 2% chlorhexidine gluconate.
Halitosis is a common complaint of one third of the population. It is commonly known as 'bad breath'. The causes of halitosis can both be intraoral (90%) as well as extraoral (10%). Malodor of oral et...
Medical and Biotech [MESH] Definitions
A disinfectant and topical anti-infective agent used also as mouthwash to prevent oral plaque.
Antimony complex where the metal may exist in either the pentavalent or trivalent states. The pentavalent gluconate is used in leishmaniasis. The trivalent gluconate is most frequently used in schistosomiasis.
An enzyme of the oxidoreductase class that catalyzes the reaction 6-phospho-D-gluconate and NADP+ to yield D-ribulose 5-phosphate, carbon dioxide, and NADPH. The reaction is a step in the pentose phosphate pathway of glucose metabolism. (From Dorland, 27th ed) EC 188.8.131.52.
Inorganic compounds that contain chlorine as an integral part of the molecule.
An oxyacid of chlorine (HClO) containing monovalent chlorine that acts as an oxidizing or reducing agent.
