Active clinical trials for "Periodontal Diseases"

The goal of this clinical trial is to test in 10 patients with advanced furcation involvement on molars. The main question[s] it aims to answer are: • Is it possible to carry out root resection without endodontic treatment on molars? Tooth vitality will be checked (positive response to cold test). Root resection will be carried out under local anestesia. Following visits will be carried out for re-evaluation/maintenance according to clinical care every 3 mounths until 3 years follow-up.

This study aims to evaluate the clinical results of non-surgical periodontal therapy performed with micro-instruments compared to traditional approach (standard curettes) after 6 months of follow-up. The patients enrolled, subject to written informed consent, will be divided into a Test group (T) and a Control group (C) through a randomization process. Both groups will be motivated on the rules of oral hygiene, treated scrupulously and monitored monthly for 6 months, at the end of which the final data will be collected for statistical processing (in particular by analyzing the difference between baseline and after 6 months of the parameter "probing depth" or PD).

In the first part, after a brief introduction, the advantages and disadvantages of immediate dentures are compared. There is a detailed discussion on assessment and treatment planning which includes history taking, examination of the soft and hard tissues, current prostheses, occlusion as well as discussion on investigations required and formulating a diagnosis. The first part ends with a summary of types of immediate dentures and denture designs.

Periodontal diseases are infections cause by dental plaque (Socransky, 1970). Risk factors are present which modify the course of disease progression. One of these risk factors is tobacco smoking, which was first evaluated by Pindborg in 1947 and later by Grossi et al. in 1995. They found that tobacco smoking was strongly associated with attachment loss, bone loss, and lastly, tooth loss. Tooth loss in one of the most visible results of periodontal disease, which negatively affects physiological and psychological patient's life. The effects of cigarette smoking on periodontal status are independent of the plaque index and oral hygiene of the patient, due to the direct influence of tobacco on periodontal tissues. Several studies have demonstrated the effectiveness of periodontal therapy in reducing the rate of tooth loss as well as the importance of patient compliance with periodontal maintenance therapy and adequate oral hygiene practice in achieving this reduction. Compliance is the main problem faced in periodontal maintenance therapy. Low rates of compliance and patient adherence to a maintenance program was reported in the literature. Periodontal maintenance therapy can be considered a critical factor for success in controlling periodontitis and in the long-term maintenance of teeth. In addition, neglecting a regular periodontal maintenance therapy program has been associated with increased risk of reinfection and progression of periodontitis, as well as increased tooth loss. The establishment of a criteria for time interval between different supportive periodontal maintenance visits, is still controversial. Smokers are associated with low level of compliance to prevent being constantly reminded of quitting smoking as well as the health complications associated with the habit. There is a void in the literature addressing the direct influence of compliance and adherence in periodontal maintenance therapy and its contribution to arrest periodontitis progression, minimizing tooth loss, specifically in tobacco smoking patients, whether they are regular or irregular compliant with a long term follow-up up to 40 years. On the other hand, there is moderate scientific evidence that the independent effect of smoking is associated with the occurrence of tooth loss in individuals undergoing periodontal maintenance therapy. Lastly, only very few studies reported the specific outcome of periodontal maintenance therapy on tooth loss in regular and irregular compliant smokers compared to regular and irregular compliant non-smokers. The focused question in this study is "Does periodontal maintenance therapy affect annual tooth loss rates differently in regular and irregular compliant smokers and non-smokers?".

This research study is designed to evaluate the chewing gum's ability to modulate the oral microbiome in human participants, in addition to its safety.

Periodontal disease is a chronic condition affecting the teeth and surrounding support structures, characterized by tooth loss and alveolar bone loss. Sanative therapy (ST) is the gold standard non-surgical treatment for periodontal disease and involves mechanically removing the subgingival bacteria from the periodontal pockets. Regular periodontal maintenance appointments are needed to maintain periodontal health after ST. Moreover, the periodontal health of individuals not requiring ST is also dependent on regular hygiene appointments. Due to Ontario's March 2020 COVID-19-related clinic closure for approximately 3 months along with a reduced numbers of appointments available due to guidelines of professional bodies and public health beyond this period of time, many appointments were considerably delayed or cancelled. The effects of this disruption to periodontal health in male and female patients who have undergone ST and continue with maintenance appointments or who attend for regular hygiene appointments have not yet been investigated.

The Hamburg City Health Study (HCHS) is a large, prospective, long-term, population-based cohort study and a unique research platform and network to obtain substantial knowledge about several risk and prognostic factors in major chronic diseases.

Determining whether in the mouth there are differences between the participant groups in the nature and activity of mucosal innate immunity, in immune responses to SARS-COV2 antigens, or in the oral microbiome

Background: - Gum disease is a condition in which the tissue around the tooth root becomes swollen and infected. This condition can cause tooth loss if it is not treated. Who gets gum disease and how bad it will be depends on (1) the different bacteria in the mouth and (2) how the immune system of an individual handles these bacteria. Researchers want to look at the oral bacteria and genetic immune problems of different people to learn how these affect gum disease and other conditions of the mouth. Objectives: - To study how immune system problems may lead to problems in the mouth, including gum disease. Eligibility: Children and adults at least 7 years of age who have genetic problems with their immune system. Healthy adults that have periodontal disease Health adults that do not have periodontal disease Design: This study will involve a screening visit and a study visit. Participants will be screened with a medical history, blood work and a full oral and dental exam, including dental x-rays and photos. The study visit will involve collection of blood, urine, and other samples, including saliva, plaque, and gum swabs. Any abnormal tissue will sampled for a biopsy. Additional oral and dental exams will be performed. Participants will also answer questions about any current medical or dental problems.

Studies suggest that chronic exposure to psychological stress can lead to oral health deterioration, alter the immune response, and possibly contribute to increased inflammation, which can impact the physiological healing of periodontal tissues. People with psychophysiological stress disorders tend to acquire unhealthy habits, leading to less self-care, incorrect nutrition, smoking, alcohol consumption, and reduced physical activity. This cross-sectional study aims to evaluate the correlation between periodontal health and psychological stress. Patients between the ages of 35 and 70 will be recruited. Each patient must be visited and a periodontal assessment must be performed, recording the percentage of bleeding on probing and the Periodontal Screening and Recording (PSR). Subsequently, patients will be administered the Sheldon Cohen Perceived Stress Scale (PSS) and the Mindfulness Awareness Attention Scale (MAAS) questionnaires.
