Filter by:The goal of this clinical trial] is to learn about the effect of methylphenidate in children and adolescents with KBG syndrome. The main question it aims to answer is: • What is the effectiveness of methylphenidate on attention deficit and ADHD-related symptoms in children and adolescents with KBG syndrome? Participants will receive multiple blocks of treatment with methylphenidate and placebo and fill out various questionnaires.
This study aims to evaluate the clinical performance of the zirconia laminate veneer, a minimally invasive prosthetic restoration
To assess the prevalence of dental anomalies in the deciduous dentition in children with oral clefts and to investigate the associated risk factors.
This aim study aims to compare clinical effectiveness of customized lingual brackets and conventional labial brackets in alignment period in a sample of Class I malocclusion patients treated on a nonextraction basis.
The aim of this study is to compare the effectiveness of using heat-activated NiTi with superelastic NiTi archwires during the initial phase of orthodontic treatment. Primary Objective: To compare the difference in the amount of crowding in the lower incisors after 4 and 8 weeks from the start of treatment. Secondary Objectives: 1. To compare the amount of orthodontically-induced inflammatory root resorption (OIIRR) in the apical region of mandibular central incisors between the two groups of archwires 2. To compare the amount of pain perception between the two groups of archwires during the 1st week after each wire placement.
All ceramic crowns are indicated in case of mild to moderate discoloration, restoration of traumatized or fractured teeth and abnormal tooth anatomy. The success of dental restorations is determined by four main factors: biocompatibility, aesthetic value, resistance to fracture and marginal adaptation. . An inadequate marginal fit may compromise the longevity of the restoration since cement film exposure to the oral environment can lead to its dissolution . . Polyetheretherketone (PEEK) is a polymer that has many potentials uses in dentistry. Polyetheretherketone (PEEK) can be used to support fixed dental prostheses. However, information about physio mechanical characterization is still scarce. Aim of the study: - The aim of this study is to evaluate the internal fit of milled BioHPP PEEK-based versus zirconia-based single crowns.
Although the metal-ceramic system is still widely used to fabricate crowns and fixed partial dentures and is considered as the standard treatment in dentistry, aesthetic concerns have stimulated the development of new dental tooth-colored systems as PEEK. BioHPP PEEK is 20% ceramic reinforced, semicrystalline, thermoplastic and radiolucent polymer for extreme durability especially for frameworks for fixed and removable dental prostheses. It has many advantages as low density, light weight, shock absorber, biocompatible and venerable with composite resin. The aim of this study is to evaluate the clinical performance of milled BioHPP PEEK-based single crowns and compare them to metal-based single crowns.
If the patients's teeth are weak or the mouth dose not open well, the lightwand is a useful device when endotracheal intubation is necessary. Therefore, if the appropriate position of the light beam is determined and the distance of the light source suitable for intubation using the lightwand is obtained from anatomical structures such as thyroid cartilage and cricoid cartilage, it is clinically useful. Because it can prevent unnecessary deep insertion or shallow insertion that can cause damage to anatomical structures during intubation.
Dental implants are a valid and reliable method to replace missing teeth. The major requirement for their success is an adequate volume of bone into which they can be placed. One widely used method to augment bone at the time of placing the implant is to use a bone substitute rather than taking a block bone graft from the patient. Successful augmentation in the vertical direction has often proved difficult, however, the investigators have developed a technique to achieve this in the investigators patients using a synthetic bone substitute, Osteon (Implantium, CE0120) in an attempt to avoid patients having to undergo another unnecessary surgical procedure.
The purpose of this trial is to evaluate the anticaries remineralizing potential of a toothpaste containing 500 ppm fluoride plus fTCP technology relative to a commercially available toothpaste via a double-blind cross-over in situ (or intra-oral) clinical model, whereby approved human participants will wear an orthodontic appliance fitted with an enamel specimen for the duration of a leg (28 days). There will be two test legs.
