Filter by: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.
There is a deficiency in literature which compares the blending effect and color matching of translucent shade bulk-fill resin composite with shaded bulk-fill resin composite. So in this research color matching and blending effect will be instrumentally measured the by a spectrophotometer. A visual assessment also will be done in-vivo and ex-vivo.
Currently, the real scope of sealants (AS) is poorly documented in temporary dentition and its effectiveness has not been demonstrated. Yet it seems reasonable that the AS in temporary dentition could slow the specific development of carious lesions in early childhood. In addition, this non-invasive approach could delay the conventional food and thus save financial costs for more complex treatments. Finally, the installation of AS could afford, as demonstrated in adult teeth, lowering the cariogenic bacteria prevalence engaged in the caries process.
This study investigated if computer games can be effective at changing the way children take care of their teeth. We a museum exhibit with 3D virtual reality games called "Attack of the S. Mutans!" Our hypothesis was that children who played the games and visited the exhibit would show improved attitudes about oral health, which would translate into improved brushing and self-care habits. In this randomized controlled study with school children aged 8-12, we compared the outcomes for three groups: Group 1) Visited Attack of the S. Mutans!; Group 2) Experienced a hands-on classroom presentation about virtual reality being used for healthcare; Group 3) Received no-treatment.
This study questions the interest of fluoride varnish dental application in preventing tooth decay in a population of institutionalised elderly people.
The purpose of this study is to determine if regular rinsing with chlorhexidine is effective as a long-term preventive method for reducing the incidence of tooth loss in low income older adults. The true end-point of the study is tooth loss after five years of regular rinsing with chlorhexidine or a placebo; surrogate endpoints are periodontal disease, root and coronal decay.
