Filter by:Symptoms of periodontal disease are tissue destruction and destruction of the alveolar bone which supports the tooth. Wnt way (wingless-type MMTV integration site family) plays a role in the regulation of bone homeostasis in periodontal disease-induced bone resorption. The Wnt / β-catenin signal is controlled by physiological antagonists, including dickkopf released from osteocytes-associated protein 1 (DKK-1) and sclerostin (SOST). Thus, Wnt inhibitors SOST and DKK-1 affect bone mass changes. Bisphosphonates used in osteoporous treatment are selective inhibitors of bone resorption. In the serum of postmenopausal osteoporotic women treated with bisphosphonate, short-term and decreased DKK-1 level during the treatment, and increased SOST in the late period were reported. Increased bone formation after bisphosphonate treatment in postmenopausal osteoporotic patients has been associated with increased serum SOST level. The aim of our study is to investigate the effect of bisphosphonate in patients with post-menopausal osteoporosis on the bone demolition metabolism in periodontally healthy and periodontally diseased tooth regions and gingival health with the clinical data by investigating the SOST and DDK-1 molecules that play role in bone destruction mechanism.
Neopterin is an early and valuable biomarker of cellular immunity, shown to be a sensitive assessment parameter for cell-mediated immune reactions. Hence determination of neopterin concentrations in distinctive body fluids is of diagnostic interest in a wide range of T lymphocytes and macrophages originated diseases. Increased neopterin production is also found in infections due to intracellular living bacteria and parasites. Neopterin concentration is directly proportional to the reactive oxygen species levels and is inversely related to the serum concentration of antioxidants like alpha-tocopherol. Hence it can be regarded as a marker of reactive oxygen species formed by the activated cellular immune system. Consequentially this is useful for predicting the prognosis and diagnosis of severe form of periodontal diseases. Menopause accomplishes a wide range of changes in women's body, and the oral cavity is also not exceptional. As exalted levels of ovarian hormones, detected in pregnancy and oral contraceptive usage, can lead to an increase of gingival inflammation. On the contrary, menopause shows depleted levels of ovarian sex steroids, which also causes worsening of gingival health. Post-menopause was found to be more aggressive and destructive in nature compared to pre-menopause. It has been assessed that the prevalence of oral discomfort was found to be significantly higher along with low flow rates of the saliva with the presence of periodontal disease more frequently. Studies demonstrated that non-surgical periodontal therapy reduces inflammation and improves periodontal status. Therefore it can be assumed that overall inflammatory markers also reduce after non-surgical periodontal therapy.
ProlacSan probiotic lozenges and gels contain L. plantarum and L. brevis strains with proven in vitro antimicrobial activity against P. gingivalis. In our study we aim to investigate proposed benefit of ProlacSan as adjunct to conventional initial periodontal treatment in a group (n = 40) of Grade III and IV periodontitis patients. Patients will be randomized in two groups receiving either probiotic (n = 20) or placebo (n = 20) after completion of nonsurgical treatment within 7 days. Before treatment and after three months, standard periodontal parameters will be measured by masked examiner and plaque samples harvested for cultivation of 9 most relevant periodontal pathogens. One lozenge per day of probiotic/placebo will be used during 3 months healing period. Primary outcome measures will be the number of persisting sites per patient that need additional surgical treatment defined as sites with probing depth > 4 mm and bleeding on probing.
The aim of the present study is to study the influence of periodontal therapy (non-surgical) on the severity of erectile dysfunction(ED) among patients with chronic periodontitis and moderate or severe ED.
PUFA Index was introduced to detect the clinical consequences of untreated dental caries. To date, there are no studies on the reliability and accuracy of the PUFA index as a screening tool. Other than indices, radiographs were sometimes used as a screening tool using the validated Periapical Index (PAI). The aim of this study was to evaluate the reliability and accuracy of PUFA and PAI in screening for clinical outcomes of untreated caries, specifically pulpal and periapical diseases. The reference standard is the clinical diagnosis, as categorized by the American Association of Endodontists. Intra- and inter-examiner reliability will be determined using Cohen's kappa. Sensitivity, specificity, positive predictive value, and negative predictive value will be calculated. Receiver Operating Characteristics (ROC) contrast estimation will be computed to compare the two index tests.
This study was performed to evaluate the effects of both periodontal treatment and smoking on the gingival crevicular fluid(GCF) levels of interleukin (IL)-17A, IL-17E, Total oxidative stress(TOS) and total antioxidant capasity(TAOC) in smoking and non-smoking patients with severe chronic periodontitis. Systemically healthy 15 smoker,15 non-smoker with chronic periodontitis were attended for the study. Periodontal status were determined by recording periodontal clinical measurements. GCF samples were collected at the baseline, at the end of initial periodontal treatment and 4 weeks after periodontal flap surgery. The data were tested statistically by the Student t and paired sample t tests.
Periodontitis is defined as loss of periodontal attachment due to microbial associated host mediated inflammation. This would lead to the apical migration of the junctional epithelium allowing the bacterial biofilm to undergo apical widespread along the root surfaces of teeth causing bone resorption (Tonetti, Greenwell, & Kornman, 2018). The main objective of periodontal surgeries is directed at complete preservation of the interdental soft tissues to achieve primary closure over the intraosseous defected sites during the early phases of wound healing. Evidence shows that surgical techniques are highly predictable in the treatment of pockets associated with deep and shallow intrabony defects affected majorly by the selected flap design. The purpose of the flap design of minimally invasive periodontal surgery is to overcome the drawbacks of conventional periodontal surgeries decreasing the surgical trauma, improving the clot stability, reducing patient discomfort post operatively and minimizing the surgical chair time (Aslan, Buduneli, & Cortellini, 2017b) Modified Minimally Invasive Surgical Technique (M-MIST) is considered one of the latest minimally invasive techniques that have been used in the treatment of intraosseous defects, this technique however entails an incision over the defect-associated interdental papilla that may jeopardize the volume and complex vascular integrity of the interdental tissues, lacking the special flap design that would emphasis clot stability for better wound healing. Where a new surgical technique turned entire papilla preservation has been developed for protection of the wound without affecting the vascularity of the area. (Pierpaolo Cortellini & Tonetti, 2015) This randomized clinical trial compared the clinical and radiographic efficacy of entire papilla preservation surgical technique (EPP) to Modified minimally invasive surgical technique (M-MIST) in the treatment of periodontal intraosseous defects in stage III periodontitis patients.
A Phase 2, uncontrolled, open-label, single arm study to evaluate the safety, tolerability and efficacy of PerioSept® (3%) as adjunct to Scaling and Root Planing in subjects with periodontitis.
Chronic periodontitis is an inflammatory and polymicrobic disease characterized by the irreversible loss of alveolar bone and connective tissue attachment of the teeth. Chronic periodontitis is the most prevalent type of periodontitis and it is seen in the great majority of the adult population. The main objective of periodontal treatment is to heal the inflammatory tissue, to eliminate unhealthy periodontal pockets, and to reduce the number of pathogenic bacteria. The traditional treatment of chronic periodontitis is debridement performed with hand tools and ultrasonic devices. However, in deep pockets, which are difficult to access, mechanical root surface debridement is not sufficient to remove the biofilm via root instrumentation. The regeneration of the periodontium aims at the reconstitution of the periodontal ligament, alveolar bone, and cementum. Platelet concentrates have gained popularity in regenerative periodontal therapy due to their autologous nature. Their regenerative potential is associated with growth factors such as TGFβ-1, PDGF, EGF, IGF-I, and VEGF, stimulate cell proliferation and regulate matrix remodeling and angiogenesis. Growth factors are naturally occurring proteins that regulate cell growth and development. They also modulate cell proliferation, migration, extracellular matrix formation and other cellular functions in epithelization. In addition, some growth factors may function as cell differentiation factors. These functions of the growth factors support epithelization following surgical periodontal treatment and reduce postoperative pain and swelling with their anti-inflammatory properties. Furthermore, studies have reported their antibacterial potentials. Different platelet concentrates such as platelet-rich plasma (PRP) and platelet-rich fibrin (PRF) are obtained when whole blood is centrifuged at different speeds and for different durations. When the literature is reviewed, it is seen that these platelet concentrates are frequently used in regenerative therapies in dentistry. In 2010, Sohn et al. obtained autologous fibrin glue (AFG), an injectable platelet concentrate, by centrifuging venous blood for two minutes in a special centrifuge device (Medifuge, Silfradent, Italy; 2400-2700 rpm). AFG is used, by mixing it with bone grafts, in the production of sticky bone, which could be an alternative to titanium mesh and bone block procedures that enable grafts to remain more stable in defects. It was found in the literature review that studies on AFG, which is a second-generation platelet concentrate, are limited in number. It was also found that these studies were conducted on sticky bone, obtained by mixing AFG with bone grafts, and there are no studies in which AFG is used alone to treat periodontal diseases. The purpose of this study is to investigate the effect of AFG, an injectable platelet concentration, on clinical parameters in the nonsurgical treatment of chronic periodontitis.
Local drug delivery provides higher concentrations in the availability of the drug at the specific infected sites with the advantage of sustained release. Periocline is a long acting , sustained release local drug delivery system consisting of 2% minocycline hydrochloride in an ointment containing microcapsule type particles. Periocline contains 20mg of minocycline in 0.5 gm of gel in a disposable polypropylene applicator (2% minocycline HCl). Research has yielded promising results with the local application of minocycline in the treatment of periodontal disease, compared with other non-surgical therapies. However, there is scarcity of reports on the use of local delivery agents with respect to new range of putative pathogens in advanced periodontitis, wherein the tissue invasive anaerobic organisms are present and possibly compromised host response, hence resulting in an exaggerated breakdown of periodontal tissues at the affected sites. The effect of Minocycline on new putative pathogens, such as Filifactor alocis and oral phylotypes of phyla Synergistetes and TM7 (referred to hereafter as oral Synergistetes and oral TM7s), has not been investigated yet. Hence, the aim of the present study is to evaluate the efficacy of a local delivery agent containing minocycline (Periocline, Sunstar, Japan) as an adjunct to SRP in the treatment of deep periodontal pockets around teeth in advanced periodontitis and the antimicrobial effect on the red complex and the new putative pathogens.
