Filter by:Dentists have recently preferred to use composite materials and restorative techniques that allow the use of simplified clinical protocols in order to reduce the time the patient spends in the dentist's chair and minimize technical sensitivity. Color selection in the clinic is a very sensitive process and is affected by environmental factors and operator-related variables. This has led to the development of single-color universal composite resins that aim to facilitate color selection. These materials have a universal opacity and several Vita shades and are recommended by manufacturers to be used in a single color layer that can match different tooth colors. In recent years, monochromatic universal composites have been developed that are supposed to be compatible with all Vita Classic Scale shades from A1 to D4. Manufacturers report that single-color universal composites can be applied to teeth of all colors without using the layering technique using different color composites. Therefore, the aim of this study is to compare the clinical performance of 2 different single-color universal composite resin materials (OMNICHROMA and Zenchroma) in the restoration of non-carious cervical lesions with the control group (Filtek Z250, 3M), which is a multi-color composite resin material, using modified US Public Health Service (USPHS) and World Dental Federation (FDI) criteria.
Wear resistance is one of the most important physical properties of teeth, and wear resistance of zirconia against artificial acrylic, enamel and composite resin denture teeth has not been clearly established. Implant-supported dental restorations present a higher threshold for occlusion perception when compared to natural teeth, which can occlusal overload mechanisms or lead to wear of rehabilitation materials or the antagonist arch. In clinical conditions, however, many other factors influence the complex interaction between dental enamel and opposing substrates: patient-related factors such as dietary habits, dysfunctional occlusion, masticatory forces, and bruxism contribute to accelerated enamel loss of antagonist teeth.
Investigating the effect of botulinum neurotoxin on the jaw-neck envelope of motion.
The 1ry objective will be to evaluate the amount of wear of onlays restorations made from VITA AMBRIA & IPS e.max Press and their opposing natural teeth. 2. The 2ry objective of the clinical trial will be to evaluate the fractures, retention, contact points, food impaction and radiographic examination of the VITA AMBRIA onlays compared with IPS e.max press onlays as defined by FDI criteria.
Our feasibility study will assess the feasibility and acceptability of Family Navigation (FN) to address attrition (dropout) in pediatric obesity management. Results from this study will help our team to plan a large randomized clinical trial to test the effectiveness of FN in reducing attrition. The investigators will enroll 108 6-to-17-year-olds enrolled in pediatric obesity management clinics in Calgary, AB and Mississauga, ON (Canada). One-half of the children will receive Family Navigation (FN) + Usual Care (UC) for 12 months; the other half will receive Usual Care only for 12 months. Overall, the study will take 2.5 years to complete. For children receiving FN, trained navigators will work with children and their families to reduce barriers that limit their access to health services and support. Navigators will offer extra services and resources, such as parking passes for clinic appointments and supportive text messages between appointments. FN is designed to complement the obesity management (Usual Care) received by children and their families. A Steering Committee with children, caregivers, clinicians, and researchers will be created to refine and improve our FN intervention throughout the study. By having better access to care, children and their families working with navigators may be less likely to drop out and more likely to attend more treatment appointments. Ultimately, the participants may be more likely to achieve success in managing obesity.
The aim of this study is to evaluate the wear produced in the short and medium term by monolithic zirconia, metal-ceramic and lithium disilicate restorations on the antagonist natural enamel in patients with fixed prostheses, assessing the factors that may influence this wear. The investigators will also analyse whether the wear of the tooth antagonistic to the different restorations differs significantly with respect to the wear of the natural tooth (control group). The null hypothesis is that there are no significant differences.
Clinical performance of indirect adhesive restorations - onlays, overlays- luted with light-cured composite resin will be evaluated.
Evaluation of hybrid composite-nanoceramic on material characteristic and clinical use over tooth wear patients.
Attrition from pediatric weight management programs is unacceptably high, with dropout ranging from 27-73%. This project will utilize a model that predicts dropout from treatment, increasing its power and accuracy through a multi-site observational study. This will result in a powerful tool that will be used to decrease attrition from pediatric weight management, with the potential for widespread dissemination to improve treatment outcomes.
This study aims to explore the relationships between tooth wear (TW) and musculoskeletal disorders (MSDs). The null hypothesis is that TW is not associated to MSDs. It also explores the influence of bruxism signs, life habits and stress on TW and MSDs.
