How to deal with morning bad breath: A randomized, crossover clinical trial

Abstract

Context:The absence of a protocol for the treatment of halitosis has led us to compare mouthrinses with mechanical oral hygiene procedures for treating morning breath by employing a hand-held sulfide monitor.Aims:To compare the efficacy of five modalities of treatment for controlling morning halitosis in subjects with no dental or periodontal disease.Settings and Design:This is a five-period, randomized, crossover clinical trial.Materials and Methods:Twenty volunteers were randomly assigned to the trial. Testing involved the use of a conventional tongue scraper, a tongue scraper joined to the back of a toothbrush's head, two mouthrinses (0.05% cetylpyridinium chloride and 0.12% chlorhexidine digluconate) and a soft-bristled toothbrush and fluoride toothpaste for practicing oral hygiene.Statistical Analysis Used:Data analysis was performed using SPSS version 17 for Windows and NCSS 2007 software (P < 0.05). The products and the periods were compared with each other using the Friedman's test. When significant differences (P < 0.05) were determined, the products and periods were compared in pairs by using the Wilcoxon's test and by adjusting the original significance level (0.05) for multiple comparisons by using the Bonferroni's method.Results:The toothbrush's tongue scraper was able to significantly reduce bad breath for up to 2 h. Chlorhexidine reduced bad breath only at the end of the second hour, an effect that lasted for 3 h.Conclusions:Mechanical tongue cleaning was able to immediately reduce bad breath for a short period, whereas chlorhexidine and mechanical oral hygiene reduced bad breath for longer periods, achieving the best results against morning breath.

Impact of Different Oral Hygiene Aids for the Reduction of Morning Bad Breath Among Dental Students: A Crossover Clinical Trial

“…This could be attributed to the fact that in Group 1 (tooth brushing) was performed by the participants which may have disrupted the formation of plaque biofilm present on the tooth surface thereby increasing the breath scores at each time interval. Similar findings were reported in previous studies carried out by Jeronimo M et al [19] and Newby et al [20]. …”

“…At the start and at the end of all experimental periods, breath scores were measured by asking the volunteers to expel air through their mouths into a hand-held sulfide monitor, Breath Alert™ (Tanita Corporation®-Japan), according to the manufacturer’s instructions as performed previously in a study done by Pedrazzi et al and Jeronimo M et al [18,19]. …”

Clinical Evaluation of Residual Tetrasodium Pyrophosphate Released from Two Different Anticalculus Flosses

“…However, the residual effect of tetrasodium pyrophosphate in the crevicular fluid may be relevant Table 1 to prevent calculus formation and maturation. Several studies have demonstrated that the combination of tooth brushing with regular flossing provides a significant improvement of oral health as a whole (23)(24)(25), but the development of a high quality preventive dental material can and should contribute to improved levels of oral health of the population. New methodologies that bring improvements over time of the active principle in crevicular fluid are required, so the production of the anticalculus effect could be maximized.…”

Effectiveness of full- and partial-mouth disinfection on halitosis in periodontal patients

“…Effective halitosis treatment is believed to require the use of scrapers to remove the tongue coating and biofilm covering the tongue dorsum (12). This removal is often described as the most effective treatment for halitosis (13).…”
