Filter by:Adhesive restorative materials are routinely used in operative dentistry to improve tooth tissues with minimal preparation, achieve more esthetic and long term restorations. Despite these efficacy to dentistry these materials still present some drawbacks like polymerization shrinkage. Postoperative sensitivity, marginal discoloration and possibly secondary caries are often associated with loss of marginal integrity in composite restorations occurred as a result of polymerization shrinkage. To achieve optimal long term performance, the requirements will be first to manage polymerization stress buildup following restoration.Low-shrinking composites with new formulas have been successful in brilliantly further developing the leader product els extra low shrinkage. The objective of this controlled clinical trial is to evaluate the clinical performance of restorative material ELS versus ELS Extra resin composite for Class I and Class II cavities that needs to be restored in permanent teeth.
This study will evaluate effectiveness of a urethane dimethacrylate (UDMA)-quaternary ammonium methacrylate (K18) resin (UDMA-K18) smooth surface sealant to prevent biofilm attachment to tooth surfaces thereby eliminating the possibility for the tooth to be demineralized. The hypothesis is that UDMA-K18 containing smooth surface sealant will be more effective at reducing enamel demineralization than the UDMA control or no treatment.
Preformed metal pediatric crowns (PPCm) are currently considered the best method of restoring Primary molars affected by severe carious lesions compared to restorations made with various restorative materials (amalgams, composites, CVI-based materials). Due to their unsightly appearance, denounced by many parents, more aesthetic zirconia (PPCz) preformed pediatric crowns have been recently marketed. In the absence of an evaluation of the latter, this multi-center split-mouth two-year randomized clinical trial (RCT) proposes to to investigate the effectiveness of PPCz for the management of dental caries or structural anomalies. More specifically, the primary objective of this RCT is to assess in primary molars the success of PPCz in comparison with PPCm. The control treatment will be PPCm since this is the standard crown option. One hundred children and one aged at least 4 years must be recruited in ninedepartments of Pediatric Dentistry in the university hospitals of Bordeaux, Lille, Nancy, Nantes, Nice, Paris 1&2, Strasbourg and Toulouse. They will be included if they have two similar primarymolars of the same arch (for example first right and left maxillary primary molars ) and equally affected, to be crowned. The two types of crowns to be used in the same child, PPCm(3M Espe) and PPCz(Ezpédo), will be affected by randomization using a computerized and centralized system: primary molars will first be allocated to PPCm and, one to two weeks later, the contralateral primary molar will be restored by PPCz. The children will be checked every 6 months for a period of 2 years after the placement of the two types of crowns . During these four control visits, primary and secondary outcomes will be assessed clinically and radiographically. The primary outcome is the success of the treatment defined by the absence of major failure. A composite measure of signs and symptoms leading to diagnosis of irreversible pulpitis or periradicular periodontitis will be used to define major failure (pain, pulp infection, dental abscess, periradicular pathology visible on radiograph). The secondary outcomes are parental and child satisfaction (size, form and color), retention and fracture of the PPC, the wear of the antagonist tooth, the gingival state near PPC using the indices Löe and Silness to record plaque index (PI), gingival index (GI) and depth of the pocket (DI) on the crowned tooth and the two adjacent ones. Each center has a trained and / or calibrated operator and evaluator.
This is a randomized clinical trial to test the efficacy of a parent-targeted text message-based intervention program on caries incidence and oral health behaviors (child and parent). Parents (n= 850) across all pediatric clinic sites (Boston Medical Center and Community Health Centers (CHCs); DotHouse CHC, South End Community Health Center, and Codman Square CHC) will be randomized to receive either text messages (TMs) regarding oral health or TMs regarding child wellness. The study will enroll English and Spanish speaking parents and their youngest child who is < 7 years old, has at least one tooth showing, and attends the targeted pediatric clinic to receive primary care (n= 1700). Parents will complete self-report surveys at baseline, and 2, 4, 12, and 24-months after baseline; receive and respond to TM assessments during the 4-month intervention; and will also receive TMs during a 'booster' period of one month, which will occur 12-months post baseline. Parent's children will be assessed for caries by a clinical oral examination performed by licensed Clinical Examiners at baseline, 12-and-24-months post-baseline.
The main aim of this study is to investigate potential associations between maternal pre- and postnatal vitamin D level and oral health outcomes (caries and developmental defects of enamel) in their children at 7-9 years of age.
Approximately 40 people will participate in this study. This study will compare two different methods of fluoride application. Both methods are currently used in dental practice and both have been shown to be effective. If the participant chooses to participate in this study, participant will be asked to either wear a small tray that has been custom made to fit into the mouth into which fluoride is placed and worn for 5 minutes at bedtime, or participant will be asked to brush fluoride onto the teeth for 2 minutes at bedtime. Participant will be randomly assigned to use one of these methods of fluoride application: participant will not be allowed to choose which method of application you prefer. Participant will be asked to use fluoride every night while enrolled in the study. The fluoride that is used in the study is approved by the United States Food and Drug Administration and is commercially available with a prescription. After the study is over, participant will need to continue to use fluoride every night for life to help reduce the risk for dental cavities in the future. During the study, participant will receive a dental examination every 3 months for a total of 4 study visits over the period of 1 year. This visit will consist of a dental examination to identify any new cavities and instructions for fluoride use. Participant will also be asked to complete a written log to document daily fluoride use and to give feedback about compliance with fluoride use.
The aim of this study was to determine if restoring primary molars with SSCs would improve children's OBF.
To minimize the effects of polymerization shrinkage in the restorative treatment, there are new composites called Bulk- Fill which the companies has developed this composites for example Tetric N Ceram(Ivoclar-Vivadent) and Filtek ( 3M ESPE). Its decreased polymerization shrinkage and properties allow the material to be inserted in one layer being quickly than traditional composite. This clinical study is designed to compare the clinical performance of the bulk fill composite resin in Class I (one-surface posterior), II (two-surface posterior) and V (cervical-surface posterior) fillings.
The objective of this study is to evaluate the clinical performance of F-Composite 2 system in Class I and Class II cavities in permanent teeth. The materials of the system can be polymerized in short time with a curing light which is part of the system. The study will be carried out as a prospective study, with evaluation of the restorations after 7-10 days (baseline), at 6 months, at 12 months, at 24 months and 60 months according to defined criteria.
the patient (n=60), with at least 3 composite resins with marginal defects , randomized into 3 groups A=Sealed with flow composite reinforced with nanofiller , B= Sealed with resin sealant , and C=Control, without intervention , and then assessed by the FDI criteria for clinical performance and longevity of restorations
