Active clinical trials for "Periodontal Diseases"

Proper plaque control is essential for to maintain oral and general health therefore, improving patient motivation is crucial for to prevent oral diseases including periodontal diseases. The aim of this clinical trial is to evaluate the effect of periodontal health education session (PHES) including the pathogenesis and consequences of periodontal diseases on oral hygiene motivation in patients with gingivitis.

In this study, the effects of periodontal disease on alveolar bone were investigated using fractal analysis method.

There is a relationship between depression and periodontal disease. This relationship may be double-sided. A psychological state such as anxiety, depression, body image, and self-esteem may be affected from the symptoms of periodontal disease.

The aim of the present clinical study is to evaluate the efficacy and safety of the novel toothpaste in patients diagnosed with gingivitis and/or periodontitis.

The objective of this study was the evaluation of periodontal condition in pregnant women and the effect of the treatment of periodontal disease upon low birth weight.

To record and compare the periodontal conditions of buccal and palatal sites in patients

The aim of the study is to determine the influence of the periodontal diseases in patients giving pre-term birth in the maternity hospital of Nantes. A French population is observed. The clinical, bacteriological and microbiological aspects will confirmed a comparative study which aim is dental prevention in the beginning of the pregnancy to avoid premature delivery.

The study purposes For periodontal applications, such as diagnosing gingivitis and periodontal disease, artificial intelligence (AI) models have been developed; however, their accuracy and technological maturity are to be evolved. The applications of such technologies in the field of periodontics are walking baby steps worldwide. The Kingdom of Saudi Arabia is moving fast in technology adoption and implementation in different sectors. However, the healthcare sector, especially clinical-related, needs original research applied to Saudi subjects. The literature in the field of machine learning applications in dentistry is limited. Although AI models for periodontology applications are still being developed, they could serve as potent diagnostic instruments. The current study was planned to add to the current gap in the literature.

Due to the phenomenon of bacterial resistance, photodynamic therapy (PDT) has been studied as an alternative to the use of antibiotics on the periodontal treatment. However, the studies show several discrepancies between the parameters adopted for PDT, which makes it difficult to compare the results and measure their efficacy. The objective of this research was to investigate the tissue dosimetric parameters used in PDT for the treatment of periodontal disease. In order to achieve this objective, the scattering pattern of light in periodontal tissue, the concentration of methylene blue in the periodontal pockets and the number of viable microorganisms were evaluated. This clinical trial included 30 patients with chronic periodontitis according to the eligibility criteria. The patients were in periodontal treatment at the Dental Clinic at the University of Nove de Julho, where the research was carried out. Three incisors from each patient were selected for the experimental procedures. The pattern of light scattering was observed through intraoral photographs. A laser with emission of radiation with wavelength of 660 nm and 100 mW of power was used. The concentration of the photosensitizer (PS) in the periodontal pockets was evaluated by spectrometer before irradiation. Methylene blue was used as PS at the concentration of 100 μM in two different formulation and vehicles to evaluate the drug dimerization. Then, the procedures of irradiation of the PDT were carried out, with 3 irradiation times of 1, 3 and 5 min. The microbiological evaluation was performed from subgengival biofilms of the periodontal pockets of the experimental sites, before and immediately after the irradiation procedures.

The oral microbiome has recently emerged as a key contributor in nitric oxide (NO) homeostasis and vascular control by increasing nitrite bioavailability. Antibacterial mouthwash containing chlorhexidine has been shown to be effective in inhibiting the nitrate-reducing activity of oral bacteria, and increasing blood pressure in normotensive and hypertensive individuals. Recent research has also shown that chlorhexidine mouthwash lowered salivary pH and increased salivary lactate and glucose. This was also associated with changes on the activity and diversity of oral bacteria that are susceptible to increase the risk of periodontal disease. On the other hand, mouthwash containing propolis has similar antimicrobial effects than chlorhexidine, but adding some positive outcomes such as increased salivary antioxidant capacity. This may suggest that propolis mouthwash modulates the activity/diversity of oral bacteria. Thus, this study aims to investigate the effect of propolis mouthwash on the nitrate-reducing activity of oral bacteria and vascular function compared to chlorhexidine in healthy humans.
