Active clinical trials for "Dental Plaque"

The objective of this study is to evaluate the efficiency of a new mouthrinse on dental plaque deposits. The study is carried out on 50 volunteers that are asked to use the mouthrinse without any other oral hygiene measure, during 4 days. It is a double bind, cross-over, randomized design: the same subjects test the active product and the placebo.

Investigation of inhibitory effect of prototype toothpaste on dental plaque formation via modified gingival margin plaque index method.

Mouthwash based on medicinal plants and propolis can be easily found in the Brazilian market even if it has not been tested in reliable clinical trials on its efficacy or possible unpleasant side effects like the ones which alter the hard and soft oral tissues. The aim of this study was to obtain preliminary evidence of efficacy of an alcohol-free mouthwash containing 5% green propolis (MGP 5%) on the control of plaque and gingivitis. Were chosen twenty-five subjects that are UFMG employees and individuals who would begin treatment on an extension project called Supportive Periodontal Therapy at the Faculty of Dentistry of Federal University of Minas Gerais, Belo Horizonte, from August to December 2009. The subjects went through a dental prophylaxis before starting rinse. They were then instructed to rinse twice a day for a minute, immediately after brushing (morning and night), using the 10 ml of the MGP 5%. After 45 and 90 days using the product the individuals returned for a clinical evaluation which considered changes in the soft and hard oral tissues and involved collecting plaque and gingivitis indexes. On their last appointment the subjects answered a questionnaire about their level of appreciation and acceptability of the mouthwash. Compliance with the treatment was also evaluated through an attendance form. For the statistic analysis we used BioEstat 4.0 and Excel 2007.

The objective of this study is to evaluate the clinical efficacy of a new toothpaste containing stannous fluoride (SnF) as compared to Colgate Fluoride Toothpaste in reducing gingivitis and dental plaque.

The effect of use of powered toothbrushing in patients exhibiting periodontal inflammation has been observed repeatedly in clinical studies conducted over a 20+ year period. Whether these subjects also had periodontitis, or not, was not a collected data metric as it was outside the scope of the Investigation. This study, therefore, will specifically include and document that a subject exhibits periodontitis upon study entry, and measure the ensuing response following professional treatment of scaling and root planing, followed by home use of the assigned study products (powered or manual toothbrushing).

The purpose of this study is to evaluate and compare plaque removal efficacy of four dentifrices following a single timed tooth brushing. Prior to each evaluation visit of the four-way cross-over study, subjects will abstain from all oral hygiene for 24 hours. At each evaluation visit, subjects will be given a pre-brushing plaque evaluation, followed by a 1-minute supervised brushing and a post-brushing plaque evaluation.

To evaluate and compare the plaque removal efficacy of a children's battery-powered toothbrush and a children's manual toothbrush following a single brushing.

To determine the effect of an amino acid on bacterial glycolytic acid formation in human interdental plaque.

Background; A new mouth rinse formulation ("Lacer Oros Acción Integral", Lacer SA, Barcelona, Spain) has been recently proposed, including O-Cymen-5-ol, potassium nitrate, zinc chloride, dipotassium glycyrrhizate, sodium fluoride, panthenol and xylitol, within its ingredients. Thus, it may be relevant to test the efficacy of this new "Lacer Oros Acción Integral" mouth rinse formulation in a RCT. Primary Objective: The primary objective of this RCT will be to evaluate the antiplaque/antigingivitis effects of the test mouth rinse. Population: Consecutive subjects in supportive periodontal therapy (SPT) will be screened at the Post-Graduate Periodontal Clinic in the University Complutense, Madrid, and enrolled in the clinical trial if they are periodontitis patients, already enrolled in a SPT, for at least 6 months, systemically healthy, with moderate gingival inflammation and complains of dentin hypersensitivity. Study design: pilot, parallel, double-blind, randomized, placebo-controlled, 12-week, clinical trial Intervention: The experimental group will use three times daily a provided manual toothbrush with a sodium fluoride dentifrice, followed by the use of the test mouth rinse (Lacer Oros Acción Integral - new formula, Barcelona, Spain). The control group will use three times daily a provided manual toothbrush with a sodium fluoride dentifrice, followed by the use of the control mouth rinse (Lacer Oros Acción Integral - new formula, without active ingredients, Barcelona, Spain). Visits: Screening, baseline, 2 and 12 weeks. Outcomes: Periodontal clinical outcomes (plaque levels, gingival condition, probing pocket depth), Stainign, Microbiological outcomes (culture and qPCR). Patient reported outcomes, compliance, adverse effects.

Over time, many different types of manual and electric toothbrushes have been produced. A systematic review has shown that some electric toothbrushes are more effective at removing bacterial plaque than manual toothbrushes. A new U-shaped electric toothbrush with silicone bristles has recently been produced that has a fully automatic and simultaneous action on both arches. However, its efficacy in removing bacterial plaque is not clear at the moment, as no randomized study has been published on this type of toothbrush. The aim of this study is to compare the efficacy in terms of bacterial plaque removal in a single use of a new automatic U-shaped electric toothbrush, compared with the usual home toothbrushing procedure, a conventional electric toothbrush, and negative control (no toothbrushing) in a group of volunteer students of the School of Dentistry of the University of Florence, Italy. Primary endpoint will be the difference in "full mouth plaque score" between before and after brushing. Secondary endpoints will be feeling of "clean mouth" evaluated on a VAS (Visual Analogue Scale) scale from 0 to 10 where 0 indicates no feeling of clean mouth and 10 maximum feeling of clean mouth. This study will be a monocentric, randomized, controlled, superiority, cross-over study, with blind examiner and 4 therapies (U-shaped electric toothbrush, usual home toothbrushing procedure, conventional electric toothbrush, no toothbrushing), carried out in a single session with an interval of one week between the 4 therapies. Study population will be students of the School of Dentistry who are healthy volunteers. Number of patients to be enrolled: 22. Inclusion criteria: age between 18 and 30 years; no fixed orthodontic appliance; presence of at least 20 teeth; Full mouth plaque score (FMPS) above 40%. Exclusion criteria: subjects with manual disabilities to perform normal oral hygiene maneuvers; subjects allergic to silicone.
