Filter by:The objective of this clinical trial is to compare the effect that the intake of beverages without sweetwners, added with non-caloric sweeteners (stevioside) and caloric sweeteners (sucrose) on oral pH and dental biofilm microbiome in Mexican adolescents. Participants will drink on different occasions a beverage without sweetener, a beverage added with stevioside or a beverage added with sucrose. The researchers will compare the changes that each one causes in salivary pH, dental biofilm pH, dental biofilm bacterial proliferation and dental biofilm microbiome.
The objective of this study is to investigate the effect of Antimicrobial Photodynamic Therapy mediated by Erythrosine and blue LED in the reduction of bacteria in dental biofilm. This clinical trial will be carried out with 30 patients who have biofilm, but without the presence of periodontal pockets, and who are being treated at the Dental Clinic of Universidade Metropolitana de Santos. A split-mouth model will be used (n = 30), with group I control - conventional treatment and group II - conventional treatment and antimicrobial photodynamic therapy (aPDT). The bicarbonate jet will be used to remove dental biofilm in both groups. The treatment will be carried out in 1 session. aPDT will be performed before cleaning/prophylaxis, only in group II. Participants will rinse with the photosensitizer erythrosine (diluted to 1mM) for 1 min of pre-irradiation time, so that the drug can stain all the bacterial biofilm. Then, the D-2000 LED (DMC) will be applied, emitting at a wavelength of ʎ = 430-490 nm and 900-1100 mW/cm2. Irradiation will be performed until the biofilm of the cervical region is illuminated for 2 min per point. Each irradiation point will be approximately 0.4 cm2. The microbiological examination will be performed from samples of supragingival biofilm collected from the gingival sulcus. Two collections will be performed in each experimental site before irradiation, and immediately after the irradiation procedure (group II) or prophylaxis (groups I and II). Biofilm samples will be collected before and after exposure, respectively, and sent to the microbiological laboratory for colony counting. After this period, the CFU's will be counted and the data will be submitted to statistical analysis for comparison of pre and post-treatment results and between groups (conventional X aPDT).

ABSTRACT: OBJECTIVE: To compare the clinical effects of Salvadora persica (miswak) oral rinse and commercial Listerein mouth wash on oral health of socially deprived madrasa girls. METHODS: Girls aged 18-22 years living permanently in a madrasa of Multan city will be recruited. Sample size and trial duration will be determined using the American Dental Association guidelines. Participants will be randomized into two interventional groups; A and B and will be either provided with Salvadora persica oral rinse and commercial Listerein mouth wash respectively. Pre, mid and post-intervention examinations will be executed by a blind and calibrated examiner using Turesky Quigley Hein Plaque and Loe and Silness Gingival indices. Statistical analysis will include descriptive statistics and two sample independent t-tests. The p-value of <0.05 will be considered significant at 95 % confidence level. KEY WORDS: Dental plaque, Gingivitis, Miswak, Mouthwash
Moringa oleifera (MO) is an extraordinary nutritious vegetable tree with high medicinal value for its antibacterial properties. Formulation of various natural dental remedies from this plant and their testing for their effectiveness might yield promising antibacterial, antiplaque and anticariogenic agents with minimal side effects. Aim of the study: Part I: The aim of this in-vitro part of the study is to formulate a nontoxic mouthwash from MO leaves extract, having antimicrobial activity, to be used in part II of the study. Furthermore, stability and efficacy of the developed mouth wash will be evaluated. Part II: The aim of this randomized controlled trial is to evaluate the antibacterial, antiplaque and anticariogenic effect of MO mouthwash compared to chlorhexidine mouthwash.
To evaluate: 1) Evaluate the efficacy of a regimen commercially available versus brush alone on established plaque and gingivitis on adolescents. The Group 1 will use the following procedure: Colgate Ultrasoft toothbrush, Colgate Total 12 toothpaste and Plax Mouthwash, and the other Group will use Colgate Ultrasoft toothbrush and Colgate Cavity Protection toothpaste; 2) The level of halitosis. Two calibrated and blinded examiners (Cohen Kappa 85%) will evaluate the gingival condition using the visible plaque indices, a simplified oral hygiene index - IHOS and gingival bleeding index, with the aid of a WHO probe. For the evaluation of halitosis levels, all individuals will respond to a questionnaire regarding personal data, general and oral health, which includes hygiene habits and received previous guidelines for the procedures to be performed in the second moment. At the next consultation, subjects will be assessed clinically for halitosis using the portable BreathAlert™ sulfide monitor (Tanita Corporation, Japan), in addition to the evaluation of the tongue flap index (ISL), pH and salivary flow. The evaluations will be in the following periods: baseline, 1, 3 and 6 months of brushing. Data will be submitted to descriptive statistical analysis to demonstrate the distributions frequency of biofilm indices and gingival bleeding. The differences in the criteria evaluated will be submitted to Fisher's exact test (α = 0.05) and their performance at different times will be evaluated by the Mann-Whitney test (α = 0.05).
Chlorhexidine is the gold standard of dental plaque prevention, but which concentration is the most effective is not known. The aim of the present study was to compare the plaque and gingivitis inhibiting effect of commercial products containing 0.2%, 0.12% and 0.06% chlorhexidine in a modified experimental gingivitis model. In three groups of healthy volunteers, experimental gingivitis was induced and monitored over 21days, simultaneously treated with the commercial solutions containing 0.2%, 0.12% and 0.06% chlorhexidine. The maxillary right quadrant of each individual received mouthwash only, whereas the maxillary left quadrant was subject to both rinsing and mechanical oral hygiene. Compliance and side effects were monitored at days 7, 14, and 21. Plaque and gingivitis scores were obtained at baseline and day 21. The commercial mouthwash containing 0.2% chlorhexidine resulted in statistically significantly lower plaque scores than the 0.12 and 0.06% mouthwashes after 21 days use, whereas no statistically significant difference was found between the effect of the two latter mouthrinses. A commercial available mouthwash containing 0.2% chlorhexidine proved statistically significant better effect in preventing dental plaque than 0.12% and 0.06% solutions.
Although several studies have assessed the efficacy of chlorhexidine in treating gingivitis and reducing biofilm formation, the side effects of a long-term use are unpleasant for patients. Melaleuca alternifolia oil has been considered as an alternative because of its anti-inflammatory properties. However, little is know about the efficacy of its nanoparticles. The purpose of this study is to compare the effect of 0.12% chlorhexidine (Periogard ®) and a nanoparticle solution of 0.3% M. alternifolia oil in reducing biofilm formation in plaque-free and plaque-covered teeth surfaces.
