NCT ID: NCT06439095 Recruiting - Saliva Clinical Trials

Interleukin-2 (IL-2), Interleukin-5 (IL-5) and Interleukin-17 (IL-17) Levels of Patients With Stainless Steel Crowns

Start date: June 2024
Phase:
Study type: Observational

The aim of this study is to investigate whether nickel hypersensitivity following stainless steel crown treatment in children aged 7-13 leads to an increase in IL-2, IL-5, and IL-17 levels by analyzing saliva samples. By doing so, the study seeks to prevent potential hypersensitivity reactions after stainless steel crown treatment. The main question it aims to answer is: Which interleukin level increases in the controls 1 week after stainless steel crowns are applied? Researchers will investigate whether there is a significant increase in interleukin levels in children's saliva before and after the procedure. Participants will: They will provide saliva samples before stainless steel crowns are applied They will visit the clinic after 1 week for check-ups and tests.

NCT ID: NCT06437262 Completed - Healthy Clinical Trials

NCT ID: NCT06354205 Recruiting - Clinical trials for Bacterial Infections

Comparison of Salivary Procalcitonin (PCT) Levels and Serum PCT Levels

Start date: June 1, 2024
Phase: N/A
Study type: Interventional

Recently, it has been seen that investigations from saliva samples could be an alternative to those from blood samples. Saliva collection is a simple, non-invasive, cost-effective, and relatively easy method, making it potentially suitable as a new diagnostic tool in pediatric patients. In the current literature, elevated levels of saliva CRP, TNF-α, IL-6, and IFN-γ have been reported in inflammatory conditions. However, while there are animal studies suggesting the use of saliva PCT levels for focal diseases such as gingival inflammation and periodontitis and as a potential tool for non-invasive detection of sepsis, there is no human study regarding its use in systemic infections. The aim of this study is to evaluate the correlation between serum PCT levels and saliva PCT levels in children suspected of SBE and to determine the diagnostic value of saliva PCT.

NCT ID: NCT06276335 Not yet recruiting - Dental Implant Clinical Trials

Influence of Timing of Implant Placement on Early Healing Molecular Events

Start date: May 1, 2024
Phase: N/A
Study type: Interventional

Dental implants have been on the market for several years and they are routinely used to replace single/multiple missing teeth with a high success rate. However, there is still a limited number of studies comparing the influence of timing of implant placement on wound healing. In addition, there is no data available on the signaling pathways and the expression of healing biomarkers involved in the early stages of osseointegration after immediate implant placement (IP) or delayed implant placement (DP). The primary objective of this study is to describe changes in the expression of inflammatory, angiogenesis and osseous biomarkers of saliva at 1, 3, 7, 15 and 30 days and of PICF at 3, 7, 15 and 30 days after immediate implant placement (IP) compared with delayed placement (DP).

NCT ID: NCT06047132 Recruiting - Periodontitis Clinical Trials

PREDICTIVE ABILITY OF A PANEL OF BIOMARKERS IN SALIVA IN HEALTHY AND PERIODONTALLY AFFECTED SUBJECTS

FLOE
Start date: October 23, 2023
Phase:
Study type: Observational

Objective: The main aim of this cross-sectional clinical study is to evaluate the predictive ability of a panel of salivary biomarkers in determining periodontal health status. Material and methods: In this observational, cross-sectional study patients attending consecutively to the Periodontal Postgraduate Clinic at the University Complutense of Madrid. The participants will be categorized into different periodontal health status groups based on the 2018 classification of periodontal diseases, including periodontally healthy, gingivitis, treated periodontitis (stable/unstable), and various stages of periodontitis. During the screening visit, participants will undergo a comprehensive medical examination to gather relevant health information, including age, gender, weight, height, waist circumference, and drug, alcohol, and smoking history. Additionally, clinical assessments, saliva samples and microbiological parameters will be recorded. A convenience sample of 100 subjects will be recruited for this pilot study with the objective to generate data for the multivariate predictive analysis. Data analyses: Descriptive statistics will be used to report the clinical variables and patients will be grouped according to the pre-established diagnostic categories (periodontally healthy, gingivitis, treated periodontitis patient. In order to determine the possible statistical relationship with the medical, biochemical and microbiological variables assessed, a crude bivariate analysis will first be performed by applying a mean comparison test for quantitative variables (ANOVA) and a proportion comparison test for categorical variables (Chi-square). Subsequently, those variables identified as relevant in the crude analyses will be included as confounding and/or interaction factors in a binary logistic regression model, considering the presence of periodontitis as a response variable, in order to obtain crude and adjusted OR values, together with their corresponding 95% CIs. Based on the results obtained in the biomarker analysis, a relevant statistical analysis will be performed, taking into account all the variables collected in the study

NCT ID: NCT06037603 Recruiting - Exercise Clinical Trials

Dual-Task Exercise for Mild Traumatic Brain Injury (mTBI)

Start date: March 6, 2024

Study type: Interventional

The investigators previously developed a virtual 14-day dual-task walking exercise program and tested its feasibility with individuals with mild traumatic brain injury (mTBI) history. The investigators will test the feasibility and efficacy of a mobile app-version (Uplode) of the same 14-day exercise program (Brain & Walk Exercise Every Day [BraW-Day]), on cognition, sensorimotor, and other functions in a group of voluntary young adults with an mTBI between last three months to two years, including student athletes, Veterans, and ethnic minorities.

NCT ID: NCT05890469 Recruiting - Dental Implant Clinical Trials

Effect of Implant Surface Material and Topography on Bone Regeneration.

Start date: December 1, 2023
Phase: N/A
Study type: Interventional

Dental implants have been on the market for several years and they are routinely used to replace single/multiple missing teeth with a high success rate. However, there is still a limited number of studies comparing hydrophilic titanium and zirconia implants. In addition, there is no data available on the signalling pathways and the expression of healing biomarkers involved in the early stages of osseointegration around zirconia surface implants placed with guided bone regeneration (GBR). This study aims 1) to describe and compare the early wound healing molecular pathways, and the 2) vascularization patterns of mucosal tissues after the placement of hydrophilic titanium or zirconia implants with simultaneous guided bone regeneration (GBR). In this study, the investigators will assess the expression of inflammatory, angiogenesis and osseous biomarkers of PICF at 3, 7, 15 and 30 days after the placement of hydrophilic titanium or zirconia dental implants with simultaneous GBR and of saliva at day 1, 3, 7, 15 and 30.

NCT ID: NCT05791149 Recruiting - Biomarkers Clinical Trials

Epigenetic Biomarkers in the Saliva for the Diagnosis of Squamous Cells Carcinoma of the Oral Cavity

EPSACO
Start date: March 3, 2022
Phase: N/A
Study type: Interventional

Head and neck squamous cell carcinoma (HNSCC) are malignant tumors originating from the epithelial mucosa of the upper aerodigestive tract. The oral cavity is the most frequent location of HNSCC (oral squamous cell carcinoma: OSCC). Tobacco use and alcohol consumption are the greatest risk factors. The Hauts de France region has one of the highest incidence rates of OSCC. The overall survival of patients with OSCC remains low, with a 5-year overall survival rate of around 60%. In addition to the oncological prognosis, OSCCs and their treatment have a significant impact on the quality of life of patients. An early diagnosis of OSCC is recommended, but it remains difficult. It can be for example challenging to diagnose OSCC in a context of oral premalignant lesions. Identifying objective biomarkers of malignancy would be an advantage and would allow better progress in the field of precision medicine and surgery for these tumors. The investigators propose to establish the diagnostic use of an optimized DNA methylation profile detected in the saliva of OSCC patients by comparing these epigenetic marks before and after tumor resection. The investigators will construct a consolidated signature of 4 genes whose DNA is subject to methylation and gene expression is restricted to cancer cells, by crossing TCGA analysis with single-cell analysis (single-cell RNA sequencing). The investigators propose to analyse DNA methylation of the corresponding genes in the saliva of n=30 OSCC patients recruited for primary surgical resection in the Department of Maxillofacial Surgery vs controls. In addition, the investigators will examine the methylation profiles before / after complete excisional surgery of OSCC. This pilot study will aim to validate the analysis of DNA methylation markers in saliva of OSCC, with the aim of improving the diagnostic precision of OSCC and, secondly, to compare these markers before and after treatment by primary surgery.

NCT ID: NCT05635929 Completed - Pain Clinical Trials

Oral Mucositis and Quality of Life With a Mucosa Topical Composition in Head & Neck Cancer Patients.

Start date: October 11, 2022
Phase: N/A
Study type: Interventional

PROMs questionnaires seem to be an effective tool to obtain a greater knowledge of the physical and emotional state of patients. Despite this, few studies have been performed using patient reported outcomes in Head & Neck (H&N) cancer patients during and after treatment. The use of a novel topical mucosa composition (Saliactive®) is studied along the use of questionnaires.
