NCT ID: NCT05939102 Completed - Dental Malocclusion Clinical Trials

Eighteen-month Orthodontic Bracket Survival Rate With the Conventional Bonding Technique Versus RMGIC and V-prep

Start date: December 10, 2021
Phase: N/A
Study type: Interventional

The aim of this study was to evaluate over eighteen months the clinical bonding failure and survival rates of the conventional bonding technique using the Transbond XT (3M Unitek, Monrovia, California, USA) and the RMGIC Fuji Ortho LC (GC Corporation, Tokyo, Japan) prepared with the V-prep. Therefore, one operator using the straight-wire technique bonded two hundred metallic brackets to upper and lower premolars of twenty-five patients requiring an orthodontic treatment. The randomized trial was a single-blind design in a split-mouth comparison. Each patient was randomly allocated one of the two bonding systems for each premolar on each side of the mouth. The bonding and rebonding techniques were standardized throughout the trial and bond failure was recorded each month for a period of eighteen months.

The study seeks to validate a novel predictive scoring model for disease progression and evaluate the impact of these treatments on mortality, admission to the intensive care unit (ICU), and time to recovery.

NCT ID: NCT05895708 Recruiting - Clinical trials for Forward Head Posture

Effect of Specific Postural Corrective Exercises on EMG Activity in Patients With Forward Head Posture

Start date: June 15, 2023
Phase: N/A
Study type: Interventional

This study investigates the effects of specific corrective exercises on EMG of masticatory and cervical muscles in patients with forward head posture. The study's design will be a prospective, double- blinded, randomized controlled trial. The participants will be randomly allocated to one of two groups: the exercise group and the control group. The training groups will perform a program consisting of two strengthening (deep cervical flexors and shoulder retractors) and two stretchings (cervical extensors and pectoral muscles) exercises. This exercise program will be repeated 4 times per week for 10 weeks, and each session lasted 30 minutes. The pre/post assessment of forward head posture will measure by using craniovertebral angle CVA. While the muscle activity EMG of the masseter, temporalis, splenius, upper trapezius, and SCM will measure pre and post-assessment using a biopic data acquisition system. There will be a high significance increase (p-value 0.000) between the pre-and-post CVA between the training groups and the control. And there will be a significant decrease in EMG of the masseter, temporalis, splenius, upper trapezius, and SCM across exercise groups compared to the control. As per the results and analysis, specific postural corrective exercises effectively decrease the EMG of masticatory and cervical muscles in patients with forward head postures.

NCT ID: NCT05889377 Enrolling by invitation - Ridge Preservation Clinical Trials

Socket Preservation Technique Using Bovine Bone, Platelet Rich Fibrin Or A Combination Of Both: A Clinical, Radiographic And Histological Assesment At 4 Months

Start date: November 3, 2021
Phase: N/A
Study type: Interventional

Post extraction alveolar bone resorption is one of the main challenges that face oral implantologists in their daily surgical practice (1). To palliate to post-extraction resorption, advanced bone grafting and regeneration techniques have been described (2). However, these procedures, although well documented and validated, still have relatively high complication rates and patient morbidity, in addition to the elevated cost and duration of treatment (3). Socket preservation is a very useful technique in order to counter post extraction resorption issues, therefore eliminating the need for future complicated and delicate regeneration procedures (4). Many biomaterials were proposed for socket preservation such as allografts and bovine hydroxyapatite (5). Recently autologous platelet concentrates such as Platelet Rich Fibrin PRF were described as a potential socket filler material (6). In the proposed protocol, fresh extraction sockets will be either grafted by a bovine bone substitute, a PRF plug or a mixture of both. Sockets will then be clinically and radiographically monitored over time to assess three-dimensional soft and hard tissue stability. Bone quality will be histologically examined at 6 months implant placement. A no graft group will serve as control. The results of this study may be of major importance since they could give an objective idea of the most efficient socket preservation technique, thus offering simple and secure oral rehabilitation solutions for both patient and practitioner.

NCT ID: NCT05880771 Enrolling by invitation - Clinical trials for Immediate Implant Placement

Immediate Implant Placement: a Clinical and Radiographic Study on Hard and Soft Tissues Retraction at One Year.

Start date: January 1, 2021
Phase: N/A
Study type: Interventional

This project consists of placing dental implants at extraction sites. Bone drilling and implant placement are performed using the flapless method with the use of a surgical guide allowing guided surgery. After implant placement, temporary teeth are immediately made and placed on the implants to guide the gingival contour. Bone and soft tissue retraction at the implanted sites are measured radiographically and digitally using surface scan superimposition over a 12-month period.

NCT ID: NCT05872321 Completed - Clinical trials for Per-operation Complications

Assessment of the New Lateral Sinus Floor Elevation Technique Using Piezosurgery: A Clinical and Radiographic Retrospective Study

Start date: July 1, 2022
Phase:
Study type: Observational

All patients who received lateral sinus floor elevation using this new piezosurgery technique, were selected. The personal file of each patient was retrieved and the following data were taken: age, sex, smoking habits, occurrence of per-operative complications (mucosal perforation, hemorrhage) and post-operative infectious complications. Pre-operative CBCT of included patients were all performed using the same Newtom VGI radiographic machine and collected from the radiology unit at the Faculty of Dental Medicine at Saint Joseph University of Beirut. The measurement of the studied factors was performed on Newtom VGI viewer software, by two evaluators J.B. and A.M.

NCT ID: NCT05870085 Completed - Child Behavior Clinical Trials

Impact of Neuro-linguistic Programming on Schoolchildren's Performance

Start date: March 20, 2023
Phase: N/A
Study type: Interventional

Neuro-Linguistic Programming (NLP) is a methodology developed in the 1970s by Richard Bandler and John Grinder, based on the idea that language and behavior are interconnected and can be systematically modeled and changed. NLP is often used as a form of psychotherapy, coaching, or personal development, although its effectiveness has been debated in the scientific community. NLP practitioners believe that our thoughts, emotions, and behavior are influenced by our internal representations of the world, which are constructed through language and sensory experiences. Changing the use of language and the perception of experiences, thoughts, emotions, and behavior can be adjusted accordingly. NLP uses various techniques to achieve this, including reframing, anchoring, and rapport-building. Reframing involves changing the perception of a situation by putting it in a different context or perspective. Anchoring consists in associating a particular state of mind or emotion with a specific physical or sensory stimulus, such as a touch or a smell. Rapport-building involves establishing a connection and a sense of trust with another person through mirroring and matching their body language, tone of voice, and language patterns.

Phase:
Study type: Observational

Background: Pregnancy-induced hypertension (PIH) is responsible for most perinatal and fetal mortality. Few programs are patient-centered during pregnancy, increasing the risks of misinformation and misconceptions among pregnant women and, as a result, malpractices. Objective: This study aims to develop and validate a form to assess the knowledge and attitudes of pregnant women about PIH.

NCT ID: NCT05848427 Recruiting - COVID-19 Clinical Trials

The LUSZ COVID-19 Severity Index: A Prognostic and Predictive Score of Mortality for Hospitalized Patients With Covid-19

LUSZ_SCORE
Start date: March 28, 2020
Phase:
Study type: Observational [Patient Registry]

The coronavirus disease 2019 (COVID-19) has spread rapidly and caused a global pandemic, as defined by the WHO, within a short period of time. The prognostic of disease severity is still a challenge and early identification of risk factors to be involved in its progression is of high importance. The scoring of variables related to worse outcomes is key for a targeted and/or advanced protocol. Besides, the need for a predictive-wide model is mandatory for hospitalized unvaccinated patients to avoid any delay in the characterization of severe illness and the development of complications. The LUSZ COVID-19 Severity Index was developed as a predictive tool based on >100 risk factors/biomarkers, that could effectively identify high-risk patients and prevent mortality.
