The aim of this study was to investigate whether cigarette smoking had any impact on the clinical outcomes 1 year after active periodontal treatment. Eligible for the study were 5680 individuals 20-85 years, referred to the specialised clinic for periodontal treatment at Gävle County Hospital between the years of 1980 and 2015. Before examination, all individuals filled in a questionnaire regarding their medical health, medication and smoking habits. Excluded were edentulous individuals and where clinical data 1-year after active treatment, or smoking habits were missing (n=1453). Complete data for analyses was available for 4227 individuals.
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.
Periodontal diseases, such as chronic periodontitis (CP), frequently occur in immunosuppressed patients, including HIV-infected patients. The immunosuppression resulted by the HIV infection can justify the high frequency and the difficult in controlling the CP in this group of patients, raising the possibility of additional factors associated to the development of CP in HIV patients. The aim of this study is to determine factors that can be involved in the CP pathogenesis in HIV patients, including Candida spp presence, and biomarkers involved on the inflammatory response against the microorganisms.
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.
Aim: This study evaluated the effects of non-surgical periodontal therapy (NSPT) on the cytokine profile and the correlation to clinical parameters of patients undergoing chemotherapy for breast cancer. Materials and methods: 40 patients were allocated: periodontitis patients (P) (n=20) and breast cancer with periodontitis patients (CAN/P) (n=20). The clinical parameters: probing depth (PD), clinical attachment level (CAL), plaque index (PI), Bleeding on probing (BOP) and levels of IFN-γ, IL-4, IL-10, TGF-β, IL-17, IL-2, IL-6, IL-1β and TNF-α in gingival crevicular fluid (GCF) were evaluated at baseline, 45 and 180 days after therapy.
In this randomized, controlled study, 18 patients with peri-implantitis were included. A total of forty dental implants were debrided with either ultrasonic instruments (test, n=20) or plastic scaler (control, n=20). Gingival recession depth (RD), keratinized tissue width (KTW), probing depth (PD), Gingival Index (GI) were evaluated at baseline and after 6 months. CBCT radiographs were used to evaluate peri-implant bone loss. Supportive and nonsurgical periodontal therapies were firstly consulted to reduce the inflammation, occurring due to the surgical treatments of the defects. The formation of bacterial biofilm on implant surfaces was removed by ultrasonic scaler and air polishing using abrasive powders or conventional plastic scaler with klorhegsidin combination.
Objective: To investigate the impact of nonsurgical periodontal treatment in patients with social anxiety disorder (SAD) and controls without phobia.
This study will seek to evaluate the predictability and efficacy of a Computer Aided Design-Computer Aided Manufacturing and additively manufactured polycaprolactone and hydroxyapatite scaffolds in these defects compared to traditional guided tissue regeneration. 40 gingival recessions associated with interproximal tissue deficiency will be divided into two groups: control group (autogenous bone + collagen membrane; n = 20) and test group (autogenous bone + scaffold; n = 20).
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.
