NCT07369297
Accurate evaluation of dental pulp health is essential to avoid unnecessary endodontic treatments. In routine dental practice, pulp sensibility is commonly assessed using electric pulp testing and thermal (cold) testing. However, these tests depend on patient perception and may be influenced by various factors such as systemic diseases, nerve damage, anxiety, trauma, or medication use. Diabetic polyneuropathy is a common complication of diabetes mellitus and may alter peripheral nerve function, potentially affecting dental pulp sensibility test responses. This clinical study aims to evaluate how the severity of diabetic polyneuropathy influences dental pulp sensibility responses and masseter inhibitory reflex (MIR) parameters. The MIR is an objective neurophysiological reflex that allows quantitative assessment of trigeminal nerve function. In this study, individuals with mild diabetic polyneuropathy, severe diabetic polyneuropathy, and healthy controls will be evaluated. All participants will undergo electric pulp testing, cold testing, and MIR measurements using standardized protocols. The primary hypothesis of this study is that increasing severity of diabetic polyneuropathy leads to reduced dental pulp sensibility responses and altered MIR parameters compared to healthy individuals. It is further hypothesized that conventional pulp sensibility tests may produce false-negative results in patients with advanced neuropathy. The findings of this study are expected to contribute to more accurate endodontic diagnosis and improved understanding of orofacial neurophysiological changes in diabetic patients.

NCT07068698
This randomized controlled study will aim to investigate the effects of thumb manipulation on hand grip strength, function, and sensation in healthy individuals. A total of 60 volunteers aged between 18 and 50 years will be recruited from Ortadağ Special Education and Rehabilitation Center. Participants will be randomly assigned to either a chiropractic manipulation group (n=30) or a control group (n=30), with an equal distribution of males and females in each group. The intervention group will receive thumb manipulation twice weekly for 4 weeks, while the control group will not receive any intervention. Outcome measures will include two-point discrimination (assessed with a discriminator), hand grip strength (measured using a dynamometer), pinch strength (evaluated with a pinch meter), and hand function (measured by the Duruöz Hand Index). Statistical analyses will be performed with a significance level set at p\<0.05. It is expected that participants in the manipulation group will show greater improvements in all measured parameters compared to the control group, suggesting a positive effect of thumb manipulation on hand-related sensorimotor functions in healthy individuals.

Interstitial lung diseases (ILD) are a group of chronic respiratory diseases that cause significant mortality and morbidity worldwide. Although there are studies in the literature comparing different lung disease groups with healthy individuals, it has been determined that there is no study comparing the exercise capacity, muscle oxygenation, physical activity level, respiratory functions, respiratory and peripheral muscle strength, inspiratory muscle endurance, quality of life and sleep quality of individuals diagnosed with ILD with healthy individuals.
NCT06591403
This study aims to examine peripheral oxygen saturation values measured in different body positions and fingers in healthy young adult individuals. The research was planned in a quasi-experimental design. The research population consisted of students/healthy young adults studying at Bursa Uludağ University Faculty of Health Sciences between January 2024 and May 2024. The research sample consisted of a total of 200 volunteer individuals who met the research limitations. The research data were collected using the Individual Introduction Form and Peripheral Oxygen Saturation Monitoring Form. A pulse oximeter was placed simultaneously on the index and middle fingers of each participant\'s active hand while they were in an upright sitting position. After the pulse oximeter was placed on both fingers for one minute, stable values seen on its screen for at least three seconds were recorded. Then, the participants were placed in a supine position, and after a 10-minute rest, similar measurements were repeated with a pulse oximeter placed on the index and middle fingers of the active hand.

NCT05358561
This study is a pioneering study in which the effect of the consumption of cakes produced with the addition of cereal-like products such as chia and flax seeds, which have high soluble fiber content, on blood glucose and insulin values, and the effect on the satiety response of individuals after consumption of cakes, will be a pioneer in many subjects. As a result of the study, the relationships between the changes in the investigated parameters and the possible changes in these parameters will be revealed. The results obtained suggest that foods rich in soluble fiber such as chia and flaxseed and foods produced with the possible synergetic effect of chia and flaxseed are used in healthy and safe products suitable for our consumption habits, and that these products are both protective and protective against the development of complications such as obesity and type 2 diabetes, cardiovascular diseases. The investigators think that it may also play a role in preventing its progress.

Purpose of the study is; to investigate the effect of exercises combined with blood flow restriction on strength, proprioception and functional motor performance in healthy individuals. There is no randomized controlled study of the effect of upper extremity exercises performed by restricting blood flow on the joint sensation of individuals and functional motor performance in healthy individuals. For this reason, purpose of the study is; to investigate the effect of exercises combined with blood flow restriction on strength, proprioception and functional motor performance in healthy individuals. Pain intensity with the numerical pain rating scale (NRS), muscle strength with digital hand dynamometer, shoulder and elbow proprioception with inclinometer, functional motor performance with Upper Extremity Closed Kinetic Chain Stabilization Test, Functional Throwing Performance Index, Single Arm Shot Put Test, Modified Pull-Up Test evaluation of 60 healthy individuals without neck and upper extremity pain, the fracture and surgical history for the upper extremity, cervical and thoracic area that prevent them to participate in the study will be made. Participants will randomly be separated into 2 groups of 30 people each. Elbow bending exercises with blood flow restriction will be performed to the exercise group during 6 weeks for 3 times a week accompanied by a physiotherapist. Control group will continue daily activities and a brochure on strengthening exercises and protection from injuries. Evaluations will be repeated 2 times and analyzed before the treatment and at the end of the 6th week. With the project, the investigators aim to improve the strength, improve proprioception and functional motor performance in healthy individuals by performing exercises restricting blood flow. With the achievement of the targets, exercises combined with blood flow restriction can be considered among the treatments protective for injuries, healing proprioception. The investigators also believe that the project will blaze the trail for the studies to be performed on athletes.

NCT01568541
There are controversial data about fluoride intake by children when tooth brushing with children's or regular toothpastes. However, a study have showed that children were exposed to a dose of 0.051 mg F/Kg/day and 0.046 mg F/kg/day by tooth brushing with children's and and regular toothpaste, respectively. Fluorides doses were too close and is questioned if there is a real clinical relevance in terms of risk of dental fluorosis. It is important to evaluate if children's toothpastes does really represent a risk of fluoride intake when compared to the regular toothpastes in terms of risk of dental fluorosis. The hypothesis is that both children's and regular toothpastes can represente risks of development of dental fluorosis and can represent similar fluoride exposure by children.
NCT01320969
It is well-established that the practice of mindfulness meditation leads to improvements in mental health and well-being and the cultivation of positive emotions. However, the neural mechanisms of these improvements are largely unknown. A few recent studies suggest that mindfulness meditation impacts the structure and function of the ventromedial prefrontal cortex, the hippocampus, and the amygdala. Interestingly, recent studies have shown that these regions are part of a brain circuit that is critical for the extinction of conditioned fear responses, and for the retention of fear extinction memory. Building on the overlap of these regions and on conceptual considerations, the project investigates whether mindfulness meditation could influence one's capacity to retain the memory of fear extinction. Meditation-naïve participants will be randomized to either a mindfulness-meditation based training or an active control training that controls for all mindfulness-unspecific components. Participants will undergo a fear conditioning, extinction and extinction recall protocol in an MRI scanner before and after the trainings. We hypothesize that participants who have practiced mindfulness meditation will show greater improvements in fear extinction memory after the course, and that these improvements will be correlated with anatomical and functional changes in the brain regions of interest. Improvements in fear extinction memory will also be related to improvements in self-reported psychological well-being. Merging the fields of an ancient spiritual tradition and a fundamental learning mechanism, the project investigates the underlying neural mechanisms of a practice for the enhancement of mental health and well-being.
