Active clinical trials for "Stomatognathic Diseases"

Enamel development defects are the result of a set of environmental, systemic and genetic causal agents that reveal a multifactorial etiology model, which in anterior teeth produces a serious aesthetic problem, converted into a problem of visual perception. In hypomineralized enamel, light rays encounter multiple interfaces between organic and mineral fluids, with different refractive indices. At each interface, the light is deflected and reflected, producing an overexposed "optical labyrinth" that is perceived as a yellow, white, or brown stain. The term "infiltration" has been modified and developed commercially in Germany for the treatment of non-cavitated caries on smooth and proximal surfaces, in which the porosities of the enamel lesion are infiltrated with a low-viscosity resin, thus creating a barrier of diffusion, without the need for any type of additional material on the tooth surface. An added positive effect of infiltration with the queens is that the enamel lesions lose their whitish appearance when the microporosities are filled, mimicking the area of the lesion with the remaining healthy enamel. This effect is what has led clinicians to adapt this treatment for the management of enamel defects. Given the growing interest in the treatment of opacities in the anterior sector, due to the demanding contemporary aesthetic requirements, and the increased acceptance of minimally invasive therapies, the need has been seen to seek greater predictability for the treatment of defects. of conservative enamel from an early age and offer effective therapeutic alternatives.

Is an in vivo study to test the effectiveness of the reciprocating system Reciproc blue and the rotating system VDW.ROTATE in primary molars.

The purpose of this randomized clinical trial is to compare the clinical/radiographic success of Hall technique and modified Hall technique in the treatment of primary molars with deep dentine carious lesions in children (3-12-year-old). The secondary aim is to examine the effect of marginal ridge breakdown level on treatment success.

Autogenous bone graft has been considered the gold standard in Guided Bone Regeneration (GBR) technique used for bone augmentation. However, there are disadvantages associated with autograft use such as limited amount of available bone and increased morbidity for the patient at the sampling site. Several biomaterials have been used as a replacement of the autogenous bone. Viral-inactivated bone allograft powder is an alternative that has proven efficacy and tolerance. This study aims to assess the non-inferiority of viral-inactivated allogeneic bone paste compared to a viral-inactivated cortico-cancellous allogenic bone powder in achieving the ideal bone volume.

Introduction. Dental fear and anxiety (DFA) is a condition that affects approximately a quarter of children and adolescents. Lack of patient cooperation due to DFA can create an environment of stress, often obligating dentists to end appointments prematurely. Virtual reality use could improve DFA in children with special health care needs (SHCN) undergoing dental procedures. Aim. Assess the feasibility and acceptability of VR immersion as a tool to reduce dental fear and anxiety in pediatric special needs patients undergoing dental procedures and gain insight on parents and healthcare providers perspectives on the use of VR during dental appointments. Methods. This pilot randomized controlled trial study will follow a parallel design including two groups: A control group (clinic's standard care) and an experimental group (virtual reality). Twenty participants will be randomized to either group. Recruitment will be carried out at the dental clinic of the Centre Hospitalier Universitaire Sainte-Justine, a tertiary-quaternary care center that mostly serves pediatric patients with SHCN. The experimental group will receive the VR video game Dream designed specifically for this study. It aims at reducing anxiety in children aged 6 to 17 years old by mean of immersive distraction. The VR headset offers children with the ability of viewing the game they are playing in real time while simultaneously obstructing the partial view they would normally have of the procedure. The primary outcome will be assessment of dental fear and anxiety in children using both observation-based proxy assessment with the Venham Anxiety and Behavior Rating Scale (VABRS) and a physiological biomarker such as the level of salivary alpha-amylase. Sociodemographic characteristics, measures of level of satisfaction of parents and healthcare professionals, occurrence of side effects and any deviation from normal procedure length will also be collected. Analysis will be carried out using statistical analysis software SAS (version 9.4; Cary, NC, USA). Descriptive statistics will be conducted for demographic and clinical variables and will be used to present parents and healthcare professionals' satisfaction levels, and also procedural time. Discussion. The investigators believe that the results of this pilot study will provide a better understanding of the feasibility and effect of VR on DFA in children with SHCN.

This study aims to characterize the healing pattern following soft tissue augmentation procedure concomitant to implant placement.

The aim of the present study is to evaluate Mineral Trioxide Aggregate and Biodentine in direct pulp capping, partial pulpotomy, and pulpotomy in primary molars.

Preserving primary teeth is essential for many aspects such as the child's growth and development, esthetic, functional, psychological, and dental arch integrity aspects. a randomized blinded controlled clinical trial aimed to evaluate the clinical and radiographic success of Zinc Oxide-Ozonated Olive Oil as root canal filling materials for primary molars compared to Zinc Oxide-Olive Oil & Zinc Oxide-eugenol. 90 primary molars of 30 children aged between 4-8 years with pulpally involved primary molars, are equally divided into 3 groups which treated with Zinc Oxide-Ozonated Olive Oil , zinc oxide -olive oil and zinc oxide eugenol as obturation materials following pulpectomy procedure. The subjects were followed up clinically and radiographically at 3, 6 and 12 months.

To evaluate immediate implant placement feasibility and esthetic outcomes in severely damaged sockets that received simultaneously bone reconstruction (cortical bone shield) and implant placement versus intact sockets that needed no reconstruction and had immediate implant placement.

The objective of this study is to compare the effect of Tropolone containing mouthwash versus CHX 0.2% mouthwash in reducing intraoral microorganism. Randomized clinical trial study
