Active clinical trials for "Periodontitis"

This study was performed to evaluate prospectively the diagnostic utility of a blood IgG antibody titer test against periodontal pathogens.

This study is being conducted to test the ability and accuracy of a new instrument in the diagnosis of periodontitis (gum disease) by using fluids from the mouth. The diagnosis instrument will test two types of fluids, gingival crevicular fluid (GCF) and saliva. GCF is the fluid that accumulates between your teeth and gum tissue. The fluids will be collected in three ways: 1. Direct GCF sampling 2. GCF rinse sampling and 3. Whole saliva. A total of 100 adult patients will participate in this study. These subjects will be of two patient populations: 1) diseased population, with active gum disease; and 2) a low-risk disease population, with no active gum disease. Patients will be seen 6 times over the course of the study over a period of approximately 12 months. At each visit the patient will undergo oral fluid collection, as previously described, and thorough examinations of the mouth, including the taking of measurements for study purposes. Patients will also have radiographs taken at baseline, month 6, and end of study visits.

The goal of this observational study is to compare the prevalence of peri-implantitis between periodontitis and nonperiodontitis sites treated with alveolar ridge preservation. The main question it aims to answer is: • whether the occurrence of PI is associated with reasons for dental extraction because of periodontitis and nonperiodontitis after alveolar ridge preservation. Researchers will compare the prevalence of peri-implantitis between periodontitis and nonperiodontitis sites treated with alveolar ridge preservation.

The goal of this observational study is to test periodontitis classification ability of ChatCPT. The main questions it aims to answer are: question 1: Could ChatCPT classify periodontitis? question 2: Is there a better result if ChatCPT is trained for perodontitis classification?

Macrophage surface markers (CD80, CD163 and CD206) will be evaluated in periodontally healthy gingiva, healthy peri-implant mucosa, and periodontitis and peri-implantitis lesions.

Prevalence of Periodontitis on a Sample of Adult Egyptian Population: A Cross-sectional study

Chronic obstructive pulmonary disease and periodontitis are chronic inflammatory diseases. The study aims to determine if the genetic polymorphism of SERPINA1 gene in patients with COPD serve as a risk factor for developing periodontitis.

The investigators planed to observe the microbiome of an aggressive periodontitis patient, during mechanical treatment, surgery(if indicated) and implant placement. The investigators designed to observe the changes after mechanical treatment.Then, the investigators will compare the sub-mucosa microbiome of implant and the subgingival community. The investigators expected a different community after treatment, and there could be similarity between implant and nature teeth.

The aim of this study is to find out if one blood group phenotype is more responsive than the others to the nonsurgical periodontal treatment.

To assess the periodontal status in the patients with depression. Evaluation of periodontal status in patients with mild depression. Evaluation of periodontal status in patients with moderate depression. Evaluation of periodontal parameters in patients without depression.
