Gum disease is a common disease, which affects 45% of the UK adult dentate population. It is caused by bacteria in dental plaque, which produces inflammation and a deepening of the natural crevice between the gum and the tooth surface. A crevice of 3mm is considered to be within the normal range, but anything ≥4mm is considered to be abnormal and is called a "pocket". Standard treatment of gum disease is mechanical cleaning aimed at removing bacteria off the root surfaces of the teeth. For most teeth, in the majority of patients, this can be achieved by root surface debridement (RSD), which involves passing instruments into the gum pockets to clean the roots. Previous studies have shown that the outcome of treatment is less effective when the pockets are deeper, or where there is bone or root anatomy which makes access for RSD difficult. In such instances additional approaches, such as repeating RSD, surgical access, or the additional use of antibiotics are considered. This clinical study will investigate the benefits and drawbacks of using a light source and dye (photodynamic therapy - PDT) as an additional treatment compared to the standard treatment of RSD alone. Patients with chronic gum problems who have undergone 1 cycle of RSD, but have residual pockets will be invited to join the study. All residual pockets will be treated with the conventional treatment of RSD. Following a random allocation process the residual pockets in half the mouth will receive additional treatment with PDT at the same appointment. Patients will be followed up for 3 months to evaluate the clinical benefits and any side effects. The aim of the study is therefore to evaluate if this localised, simple treatment can add benefit to RSD alone, thus reducing the need for antibiotics or surgery to treat residual pockets.
The main objective of this study is to compare the effect of the non-surgical periodontal treatment on serum and saliva oxidative stress parameters in patients with periodontitis and obstructive sleep apnea syndrome (OSAS) and in patients with periodontitis only.
The aim of this study is to evaluate the additional effect of antimicrobial photodynamic therapy regeneration treatment of mandibular furcation lesions when associated to bovine bone and porcine collagen membrane.
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.
Melasma is a commonly pigmention characterized by melanotic patches on the face. literature searched revealed that periodontitis and vitamin D deficiency have occurred along with anemia. Actinic associated factors may be indirectly related to vitamin D, melasma contributes to sun exposed area of face.To correlate melasma with clinical evidence of periodontitis and vitamin D serum analysis along side hb %. Patients with facial melasma between 30-70yrs of either gender formed Group A (95). Anaemia and periodontitis were Clinically checked. Additionally serum analysis of vitamin D and hb percentage were analysed. Similar procedure was carried out on controls which had Group B (95) patients with no melasma on face. The study revealed significant correlation between melasma and periodontitis with vitamin D abnormalities (p value<.05), where as insignificant correlation between melasma and Hb%. The correlation between melasma, vitamin d changes and periodontitis may prompt the clinician to check for any such changes in any patient. Melasma in patients with periodontitis and serum vitamin D changes might be a considered as a syndrome.
The present study is an effort to investigate the hypothesis that Platelet Rich Fibrin/Biphasic Calcium Phosphate may play a role in inhibiting osteoclasts differentiation and in bone loss.
This study evaluates the interaction between host immune cells and bacteria associated with periodontitis. It comprises biological material from donors with and without periodontal disease. Specifically, we collect a spit and blood sample to conduct in vitro stimulations and measurements of selected parameters related to periodontitis to clarify obscure areas in the immunologic pathogenesis of this disease.
Alendronate (ALN), commonly use bisphosphonates is proposed to have osteostimulative properties in vivo and in vitro, as shown by an increase in the matrix formation, and acts as a potent inhibitor of bone resorption. AV widely known for its wound healing, analgesic, antioxidant, antibacterial, antiviral, antifungal, immune boosting and significant anti-inflammatory properties. The present study aims to explore the efficacy of 1% ALN and AV gel as a local drug delivery as an adjunct to scaling and root planing (SRP) for the treatment of degree II furcation defects
Metformin (MF), a biguanide group of anti-diabetic drug has been shown to enhance osteoblasts differentiation and inhibit osteoclast differentiation in vitro, thus may exhibit a favorable effect on alveolar bone. AloeVera Gel had also been used in dentistry and showed good results.The present study aims to explore the efficacy of 1% MF gel and aloe vera gel as a local drug delivery system in adjunct to scaling and root planing (SRP) for the treatment of subjects with chronic periodontitis (CP) with intrabody defects.
