A Randomized Parallel Study to Assess the Effect of Three Tongue Cleaning Modalities on Oral Malodor.

Objectives: The objective of this study was to compare the effects of three tongue hygiene regimens on oral malodor.

Methods: This was a single-center, randomized, parallel design study with three treatment groups. Subjects were randomly assigned to perform tongue hygiene with either the Philips Sonicare TongueCare+ BreathRx regimen (STC), Listerine Cool Mint antiseptic rinse (LCM), or tongue brushing with an ADA reference manual toothbrush (MTB).

Efficacy of stabilized chlorine dioxide-based unflavored mouthwash in reducing oral malodor: An 8-week randomized controlled study.

Purpose: To evaluate the efficacy of a mouthwash containing stabilized chlorine dioxide in reducing oral malodor when used as an adjunct to tooth brushing compared with the use of a placebo mouthwash.

Methods: This 8-week study in healthy subjects with clinically diagnosed intrinsic oral malodor was a 2-way crossover, double-blind, randomized, and controlled trial design, which was conducted at a single site. Subjects were randomized to receive either unflavored, non-fluoridated, and alcohol-free mouthwash containing 0.

Comparison of efficacy of an arginine-calcium carbonate-MFP toothpaste to a calcium carbonate-MFP toothpaste in controlling supragingival calculus formation and gingivitis: a 6-month clinical study.

Purpose: To investigate whether the long-term use (6 months) of an arginine-calcium carbonate-MFP toothpaste would affect calculus formation and/or gingivitis when compared to a calcium carbonate-MFP toothpaste.

Methods: This was a double-blind clinical study. Eligible adult subjects (120) entered a 2-month pre-test phase of the study.

California dental hygienists' knowledge, attitudes and practices regarding herbal and dietary supplements.

Purpose: As more Americans use dietary supplements, the potential for increased adverse effects increases. The purpose of this study was to identify the current knowledge, attitudes and practice behaviors among California dental hygienists regarding herbal and dietary supplements (HDS).

Methods: A stratified random sample of 1,203 registered California hygienists were surveyed.

Antiplaque/antigingivitis efficacy and safety of a cetylpyridinium chloride/zinc gluconate mucoadhesive gel. Results of a 6-month clinical trial.

This article presents the results of a controlled clinical trial evaluating a new at-home treatment to improve gingival health. Designed for overnight application at the gingival margins and in the interproximal spaces, the product is a mucoadhesive gel containing 0.10% cetylpyridinium chloride (CPC) and 0.

Clinical efficacy evaluation of calcium, phosphate, and sodium bicarbonate on surface-enamel smoothness and gloss.

This clinical study evaluated the effectiveness of a fluoride dentifrice containing calcium, phosphate, and sodium bicarbonate for improving surface-enamel smoothness and gloss relative to a commercially available fluoride and silica-containing dentifrice. Balancing for baseline surface-enamel roughness and gloss, 113 healthy adult volunteers who met the inclusion criterion for daily acidic drink consumption were randomized to receive 1 of the 2 products. Subjects brushed their teeth using the assigned dentifrice and a soft-bristled adult toothbrush for 1 minute twice daily for 3 months.

Disability self-assessment and upper quarter muscle balance between female dental hygienists and non-dental hygienists.

Purpose: The purpose of this pilot study was to compare disability self-assessment and upper quarter muscle balance female dental hygienists and non dental hygienist females. The upper quarter was operationally defined as the shoulder and neck region. Muscle balance was operationally defined as muscle flexibility and muscle performance.

Reducing bacterial counts in dental unit waterlines: distilled water vs. antimicrobial agents.

Background: This study evaluated five chemical disinfectants to compare their abilities to improve dental unit waterline quality and assess their effects, if any, on the biofilm layer.

Methods: Sixty new dental units, with a closed-circuit water system, were used to compare microbial levels in DUWLs treated with five antimicrobials: Listerine, Bio 2000, Rembrandt, Dentosept, and sodium fluoride to a control group of sterile distilled water alone over a six-week period. For all units, the waterlines were filled with solution, left overnight, and then flushed for 30 seconds with sterile distilled water the following morning prior to patient treatment.

Reducing bacterial counts in dental unit waterlines: tap water versus distilled water.

Background: The maximum recommended level of microbial contamination of water from dental unit waterlines (DUWL) is 200 colony-forming units per milliliter (CFU/mL). This article addresses the importance of water selection in achieving that standard.

Methods: Microbial contamination in water samples from 75 new dental units, with a closed-circuit water system, were compared using combinations of tap water and sterile distilled water with and without two chemical disinfectants (bleach and 0.

Tongue piercing: impact of time and barbell stem length on lingual gingival recession and tooth chipping.

Background: The increasing popularity of tongue piercing has prompted several case reports documenting oral complications of this practice. However, there are no studies assessing potentially significant parameters. The purpose of this study was to evaluate the effect of time (years of wear) and tongue barbell size (stem length) on gingival recession and tooth chipping.
