Filter by:This study is to evaluate the benefit and tolerability of a Mouthrinse (IQP-OLP-101) in the treatment of dentine hypersensitivity.
The aim of this study is to evaluate tooth sensitivity and marginal adaptation of porcelain laminates veneers prepared with modified gull wing preparation and conventional preparation.
The objective of this clinical study is to evaluate the effect of the whitening treatment performed with the violet LED light (405-410 nm), with or without a bleaching gel, on the tooth color changes (immediate and long-term), tooth sensitivity, satisfaction of participants in relation to the technique and impact on their quality of life. After being informed of the objectives of the study, 200 participants will be selected and randomly divided into a treatment group (n = 25): G1 - 35% hydrogen peroxide (HP) (4 sessions, 1 session/week); G2 - 30% carbamide peroxide (CP) (4 sessions, 1 session/week); G3 - Violet LED (405-410 nm, 4 sessions, 1 session/week); G4 - Violet LED (405-410 nm, 4 sessions, 2 sessions/week); G5 - Violet LED associated to 35% hydrogen peroxide (4 sessions, 1 session / week); G6 - Violet LED associated to 30% carbamide peroxide (4 sessions, 1 session / week); G7 - hybrid technique HP (Violet LED + application of 35% hydrogen peroxide + violet LED) (4 sessions, 1 session/week); G8 - Hybrid technique CP HP (Violet LED + application of 30% carbamide peroxide + violet LED) (4 sessions, 1 session/week). The color evaluation will be performed at predetermined times (before and immediately after treatment, 14 days after completion of bleaching and 3, 6 and 12 months after completion of bleaching), and quantitatively evaluated by colorimetric tests (objective and subjective) and spectrophotometry. In addition, it will be evaluated the tooth sensitivity during and after (48 hours) tooth whitening (VAS Scale), satisfaction with the treatment and impact on quality of life (OHIP-14 questionnaire). The data, except for survey data of satisfaction (descriptive evaluation), will be subjected to statistical analysis to determine the homogeneity and normality of the sample and for comparison between treatment groups, considering a 5% significance level.
This is a single center, randomized control. Sixty eligible subjects will be recruited into 3 study treatment groups (n=20 per group) through computerized randomization. Subjects in group 1 will be treated with 8% arginine containing paste(Colgate® Sensitive Pro-Relief™), group 2 with 5% topical fluoride varnish (Acclean) and group 3 with self-adhesive resin (Seal and protect, Dentsply). The subjects in the study will be evaluated for tactile and air-blast hypersensitivity criteria at baseline, two and four weeks.
Objectives: This study aims to evaluate the effectiveness of preemptive administration of non-steroidal anti-inflammatory Piroxicam-beta-Cyclodextrin on risk and level of tooth sensitivity caused by in-office bleaching procedures using 35% hydrogen peroxide. Fifty patients will be selected for this triple-blind, randomized, cross-over, placebo-controlled clinical trial. Piroxicam-beta-Cyclodextrin (200 mg) or placebo will be administrated in a single-dose thirty minutes prior to bleaching procedure. The whitening treatment with 35% hydrogen peroxide will be carried out in two sessions with a 7-day interval. Tooth sensitivity will be assessed Immediately before bleaching agent removal and up to 24 hours after each session the procedure using analog visual and verbal scales. Color alteration will be assessed by a bleach guide scale 7 days after each session. Relative risk to sensitivity will be calculated and adjusted by session; while comparison of overall risk will performed by Fisher's exact test. Data on the sensitivity level for both scales and color shade will be subjected to the Mann-Whitney and Friedman tests, respectively (α = 0.05).
The aim of this clinical study is to evaluate the efficacy and dental sensitivity associated with Combined Bleaching Technique (in-office + at-home) varying in-office bleaching application under two different time protocols, and dentifrice containing arginine 8% and carbonate calcium use. One hundred eight participants who meet the study inclusion criteria will be selected. The desensitizing agent used will be a dentifrice containing 8% arginine and calcium carbonate. In each evaluation will be determined: tooth sensitivity and color. The data collected will be submitted to the factorial statistical analysis for evaluation of color and chi-square test for tooth sensitivity (α = 5%).
This study aims to evaluate the longevity and efficacy of two products potassium oxalate-basedin two concentrations, 10% and 5%, by triple randomized blind clinical trial (split-mouth) . The desensitization approach (single agent) and the long-term effectiveness (baseline, 1 week, 2 weeks, 3 weeks). Data will be collected, tabulated and submitted to statistical analysis.
The aim of this study is through a double blind randomized clinical trial, evaluate the effectiveness of different clinical protocols in the reduction of dentin hypersensitivity. The desensitization approach (single agent or associated agents) and the long-term effectiveness (baseline, 1 week, 2 weeks, 4 weeks, 12 weeks and 24 weeks) will be evaluated. Data will be collected, tabulated and submitted to statistical analysis.
A randomised, examiner blind, two treatment arm, stratified, parallel design, single-site study in subjects with at least two sensitive teeth to compare the efficacy of a test dentifrice against that of a control dentifrice in reducing dentinal hypersensitivity.
Dentinal hypersensitivity [DH] is a common condition in daily practice, especially in patients who have abrasion, attrition, gingival recession and erosion of teeth. It can affect individuals in the age range of 20-50 years.In a recent systematic review, it was reported that no gold standard treatment modality for dentin hypersensitivity has been established Thus there is a need to evaluate new formulations in different settings and in different populations and to compare those to commonly used agents seeking better results in pain relief for our patients. Studies showed that dentifrice formulations containing 8% arginine in combination with calcium carbonate and fluoride have the ability to plug dentinal tubules, by clumping of both arginine and calcium carbonate that bind with the negatively charged dentin . Aim of the study is to clinically evaluate toothpaste containing 8% arginine, calcium carbonate, and sodium mono-fluorophosphate, in comparison to toothpaste, containing 8% strontium acetate and NaF on the relief of DH in chronic periodontitis patients.
