Active clinical trials for "Periodontal Diseases"

An Artificial Intelligence platform to develop an app which improves compliance in periodontal treatments

The primary objective of this study is to demonstrate that in supra-alveolar-type defects (i.e., defects displaying a predominately horizontal pattern of bone loss), periodontal surgery with the additional use of Straumann® Emdogain will result in significantly higher Clinical Attachment Level (CAL) gain compared to periodontal surgery without Straumann® Emdogain.

Interleukin (IL)-38 is the newest member of the IL-1 family. It can bind to receptors through various pathways and regulate the formation and function of inflammatory cytokines. Periodontitis is a chronic inflammatory disease that can start with localized inflammatory reactions created by the supporting tissues surrounding the teeth against microorganisms and then result in loss of teeth. The aim of this study is to compare the IL-38, IL-1β and IL-10 levels of healthy and periodontitis individuals.

Background- In developing countries like India, seeking mental health care is still a taboo, and a lot of stigma is attached to consulting a psychiatric specialist or a counselor. This problem magnifies during postpartum period characterized by depressive symptoms in mothers indicating persistent low mood and feeling of worthlessness with easy fatigability, poor appetite, and sleep deprivation which leads to lack of interest in daily activities including oral health care. Rationale- Many studies have evaluated the periodontal status during pregnancy and its consequences but only few studies have been conducted evaluating the periodontal status during the postpartum period. None of the study has evaluated the association of Mental health and periodontitis during postpartum period. Objectives-To assess the Association between Periodontal status and Mental health in Postpartum women Methods- Periodontal Status and Mental health status (by Mental Health Inventory) will be assessed in Women during postpartum period (6-8 weeks- 6 months after delivery). Expected outcomes- Study of periodontal status during postpartum period may contribute in elucidating this interrelationship and helps to design better prevention strategies for women's mental health.

Background: There are epidemiological and preclinical studies in vivo that support the biological plausibility of the association between periodontal diseases and major depression (DM), through the hypothesis of a "leaky mouth" by periodontitis as a source of neuroinflammation. Therefore, this association should be studied in depth in carefully designed cross-sectional studies in humans to specifically assess this relationship. Objectives: Primary: determine if periodontitis can be associated with the development of DM. Secondary: (1) to estimate the prevalence of periodontal diseases (gingivitis and periodontitis) in patients with and without DM; (2) to determine whether oral, periodontal, and fecal (bacterial, viral, and fungal) metagenomic microbiomes, inflammatory mediators, and intestinal barrier integrity are associated with periodontal and mental health variables. Material and method: A cross-sectional analytical study with two groups is designed: Control group (without DM): subjects without known mental health pathologies will be included, who present a PHQ-9 index of 5 or less. They will be recruited from the control group of a population-based study PsychoBioma TRIAD (C.P. PSQ-19-2 - C.I. 19/474-E). They will be matched by age, gender, and socioeconomic status. Group of cases (MD patients): subjects with moderate DM will be selected, characterized by HPQ9 index values of 9 or higher. They will be selected among those patients who attend the Mental Health consultations associated with the San Carlos Clinical Hospital. The study will consist of three visits: Visit in Mental Health Consultations: in this visit the subject will be evaluated to determine if he meets the eligibility criteria. You will be informed of the purpose of the study and you will be invited to participate and sign the informed consent. After that, a structured clinical interview for the DSM-IV (SCID) will be conducted and the subject will fill in a series of specific scales on a study-specific electronic device [Beck Depression Inventory (BDI); UCLA Loneliness Scale, Center for Epidemiologic Studies Depression scale [CES-D]; Childhood Trauma Questionnaire short form (CTQ-SF); The World Health Organization Quality of Life questionnaire (WHOQOL); Hamilton scale (HAM-D17); Global Assessment of Functioning (GAF) Scale]. Dental School Visit: Subject will receive a comprehensive periodontal examination. A subgingival microbiological sample, a saliva sample and a blood sample will also be taken. The patient will be given a specific vial to collect stool samples. At the participant's home: the stool samples will be deposited by the participants at home in the specific collection vial.

The goal of this observational study is to compare saliva sTREM-1, sTREM-2, Presepsin levels and sTREM-1/sTREM-2 ratio of participants with/without periodontitis. The main question it aims to answer is there a relationship between saliva sTREM-1, sTREM-2, Presepsin levels, sTREM-1/sTREM-2 ratio and periodontitis. Participants will give saliva samples without any intervention

For patients having periodontal intrabony lesions, three treatment modalities were executed to evaluate the effect of protecting Leukocyte rich -Platelet Rich Fibrin harvests (applied in the bony defects) with resorbable collagen membranes. Clinical Outcomes recorded were the Plaque index (PI), Gingival index (GI), probing depth reduction (PD), Clinical attachment level (CAL), and radiographic defect depth changes. For the biochemical evaluation: levels of PDGF-BB and VEGF obtained from crevicular fluid by Perio-Paper strips were assessed using ELIZA.

In this randomized controlled trial, it was aimed to evaluate the effect of probiotics (chewable tablets) and kefir consumption in the initial periodontal treatment of periodontitis patients on the change of oral microbiota and treatment. In this clinical trial, 36 systemically healthy volunteers who were diagnosed with periodontitis who were admitted to Gazi University Faculty of Dentistry, Department of Periodontology were included. Besides the inclusion criteria, the nutritional habits of the patients were evaluated by questionnaire. For diagnosis, plaque index, gingival index, bleeding on probing, periodontal probing depth and clinical attachment level were examined. Patients were randomly divided into 3 groups; probiotic, kefir and control group. Following the periodontal diagnosis, clinical index records of the patients and subgingival microbial samples were obtained. The supragingival plaque sample was removed and the subgingival microbial dental plaque sample was gently taken with a sterile Gracey curette. In the same session, periodontal initial treatment was started. According to the groups, they were involved simultaneously with the treatment, kefir group was advised to consume kefir as a liquid once a day in 14 days; probiotics group was advised to consume as a chewable tablet once a day in 14 days; the control group was advised without additional food supplements. Periodontal indexes were repeated in the 1st and 3rd months. Subgingival plaque samples were taken at baseline and at 3 months and DNA sequencing was performed for Tanneralla forsythia (T. forsythia), Porphyromonas gingivalis (P. gingivalis), and Treponema denticola (T. denticola).

This study is designed to evaluate the efficacy and the safety of YH23537 in Korea patients with chronic periodontitis, in order to investigate the recommended therapeutic dose.

The investigators' earlier study reported a high prevalence of chronic periodontitis among obese Malaysian adult population. Non-surgical periodontal therapy (NSPT) has been shown to effectively reduce microbial load and contributes to reduction in periodontal parameters and inflammatory burden up to 6 months post-therapy. This study will cast light on the effects of obesity on chronic periodontitis (CP) patients following NSPT. The objectives of the study were to quantify and to compare the periodontal pathogens, serum and salivary interleukins in obese and non obese with CP following NSPT.
