NCT07323693
To evaluate and compare the clinical effectiveness of a Bioactive Desensitizer Gel (which releases calcium and phosphate to form hydroxyapatite) versus a standard 5% Sodium Fluoride (NaF) Varnish in reducing cervical dentin hypersensitivity (CDH) in adult patients over a period of 6 months.
NCT06238999
The overall objective of this clinical investigation is to evaluate the clinical safety and performance of the new flowable composite TM Flow for treatment of non-carious cervical lesions. Each participant receives two different fillings (test- and control material) in two different teeth. The fillings are assessed according to selected FDI criteria at baseline (7-10 days after filling placement) and after 1, 6, 12, 24, 36 and 60 months.
NCT07113847
84 patients who fulfill the inclusion criteria will be enrolled to the study. For every patient a tooth of complain which fulfill the inclusion criteria will be selected, so the total number of included teeth will be 84 teeth. Teeth will be classified into 4 groups according to the type of desensitizer used. Where in group 1 (G1) patients will be randomly assigned to "Resin-Based Desensitizer", in group 2 (G2) patients will be randomly assigned to "Laser Desensitizer", in group 3 (G3) patients will be randomly assigned to "Combination of Laser + Resin-Based Desensitizer", and in group 4 (G4) patients will be randomly assigned to "Fluoride-Based Desensitizer". For every patient, sensitivity test will be done using visual analogue scale immediately after application, three months after application and six months after application. Table 1 shows the variables of the study, and Table 2 shows the variables of the study. Each patient's name will be replaced with a case number within the group to protect the privacy of medical information and data of the patients.
NCT07034235
The aim of this study will be to evaluate the effect of wet and overwet dentin on the long-term clinical performance of two universal adhesive systems used as etch-and-rinse application mode in non-carious cervical lesions (NCCLs). Materials \& Methods: 200 restorations will be randomly placed in 50 subjects according to the following groups (n=50): AMP-wet (Ambar Universal APS Plus adhesive on wet dentin); AMP-overwet (Ambar Universal APS Plus adhesive on oversaturated dentin); PBA-wet (Prime\&Bond Active adhesive on wet dentin); PBA-overwet (Prime\&Bond Active adhesive on oversaturated dentin). For all groups, the enamel and dentin will be etched for 15s. All groups will be light-cured for 10s/1,000 mW/cm2. A resin composite will be placed by applying three increments and each one was light cured for 20s/1,000 mW/cm2. The restorations will be finished immediately with fine diamond burs and spiral polishers. The restorations will be evaluated at baseline and after 6 months by using the FDI criteria. The following outcomes will be evaluated: retention, marginal staining, marginal adaptation, post-operative sensitivity and recurrence of caries. The differences among the groups will be calculated using Friedman repeated measures analysis of variance rank (α = 0.05).
NCT06971783
This randomized, single-blind, placebo-controlled clinical trial aims to evaluate the effect of an experimental gel based on Acmella oleracea (jambú) extract, associated or not with fluoride, in reducing dentin hypersensitivity (DH) in non-carious cervical lesions. The volunteers were randomized into 4 groups according to the treatments applied: CT (control), NP (potassium nitrate), AO (Acmella oleracea) and AF (Acmella oleracea associated with fluoride). Prophylaxis with pumice stone and water was performed on the previously selected teeth and, subsequently, the gels were applied to the cervical region with a microbrush, rubbed for 10 seconds, and remained on the tooth surface for 10 minutes. Three gel application sessions were performed, with 1-week interval between them. The DH evaluation was performed at four time points: baseline (before the first session), T1 (before the second session), T2 (before the third session) and T3, one week after the final application of the products.
NCT05945173
The aim of this study will be to evaluate the effect of prolonging solvent evaporation time on the 6- and 12-months clinical performance of two universal adhesive systems used as selective enamel etch (SEE). Methods: 140 restorations will be randomly placed in 35 subjects according to the following groups: SUP5 (Scotchbond Universal Plus evaporated for 5 s); SUP25 (Scotchbond Universal Plus evaporated for 25 s); GBU5 (Gluma Bond Universal evaporated for 5 s); GBU25 (Gluma Bond Universal evaporated for 25 s). Resin composite will be placed incrementally and light-cured. The restorations will be evaluated at baseline, after a week, 6 and 12 months using the FDI and USPHS criteria. Statistical analyses will be performed using appropriate tests (α = 0.05).
NCT05029479
this trial is to test the clinical performance of a novel moisture resistant, M-TEG-P phosphate monomer based universal adhesive (YAMAKIN TMR-Aquabond0) compared to the conventional universal adhesive (3m ESPE Single Bond Universal Adhesive) in geriatric patients with Non-carious Cervical lesions (NCLLs)
NCT04707898
The aim of the study is to compare the performance of universal adhesives containing different-solvent-based in the restoration of non-carious cervical lesions (NCCLs).
NCT03086720
This study will verify the effect of the application of a substance (10% sodium hypoclorite -NaOCL) in dentin on noncarious cervical lesions, with the aim of increasing the longevity of the restorations performed in this type of lesion. The hypothesis of the present study is that the application of deproteinization solution after acid etching does not influence the failure rate of the restorations.
