Autologous Fibrin Glue Application as an Adjunct to Nonsurgical Periodontal Treatment of Chronic...
Chronic PeriodontitisPeriodontal Pocket2 moreChronic 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.
Hypochlorous Acid Mouthwash, Oral Bacteria, and Staphylococcus Aureus
Periodontal DiseasesMouthwash is one method of maintain oral health and to reduce the dental plaque and gum inflammation. However, the effects of mouthwash on oral bacteria were not consistent among different brands of them. The aims of present study were to determine the effects of a new designed mouthwash with hypochlorous acid on oral bacteria and Staphylococcus aureus. All participants were invited as a volunteer to attend this study from a private dental clinic and diagnosed by the same dentist. Patients with periodontal diseases were randomized selected as mouthwash group and mouthwash plus dental flossing device (La Chlogen, Taiwan) group. Patients for regular dental visit and without periodontal disease were invited as a control group having mouth rinse with water. After the inform consent was signed, participants completed the intervention study, saliva collection, and a simple survey under the guide of a dental assistant. Saliva samples were collected before and after the intervention for bacterial DNA extraction. A real-time polymerase chain reaction and S. aureus with serial dilutions were applied for the estimation of total oral bacterial count (TOBC) in saliva. An in vitro assay with CCK-8 reagent was apply to test the antibacterial ability of mouthwash.

Slow-release Locally Administered 0.02% Hypochlorite Formulation
Periodontal DiseasesAim: The presence of bacterial plaque is associated with the development of periodontal inflammation. The aim of this single-blind randomized clinical study was to prospectively evaluate the efficacy of two different agents in a staged approach for nonsurgical periodontal treatment in terms of clinical and patients related outcomes in a cohort of patients with periodontitis: NitrAdine® based disinfectant formula (PerioTabs®) vs Chlorhexidine 0.12 toothpaste and mouthwash 0.20. Material and methods: Patients with a diagnosis of periodontal disease (stage I-III) scheduled for non surgical periodontal treatment were randomly allocated to the preparatory home use of a chlorhexidine mouthwash or a NitrAdine® based brushing solution called PerioTabs® for 10-15 days. Active decontamination with ultrasonic scalers was performed after the completion of the preparation period. Clinical and patient-related outcomes were recorded at baseline, at the moment of professional intervention, and after 30 and 90 days from baseline.
Changes in Inflammatory State in Asian Americans Changing From Traditional Asian Diets to American...
DiabetesInsulin Resistance3 moreWe hypothesize that Asian Americans compared to Caucasians, will be at higher risk of developing a pro-inflammatory state that may contribute to the development of heart disease and diabetes when they change from a traditional Asian diet to a typical Western diet. These inflammatory responses will be reflected by the activation of monocytes as measured by protein kinase C (PKC), a known activator of monocytes. We also hypothesize that the changes of these inflammatory responses in the gingival crevicular fluid (GCF) will reflect similar changes of these markers in the plasma and monocytes. Specific aims: To compare the inflammatory responses (primarily PKC activation in monocytes), between Far-East Asian Americans and Caucasian Americans, when they change from a traditional Asian diet to a typical American diet. To correlate the biochemical changes of inflammatory responses in the plasma and monocytes with those in the gingival crevicular fluid (GCF).
Efficacy of New Alcohol Free Mouthrinses
Gum DiseaseBackground To evaluate the efficacy of two alcohol-free antimicrobial mouthrinses in reducing plaque and gingivitis compared to an alcohol-containing rinse and toothbrushing alone. Methods 160 healthy volunteers were enrolled in the parallel-design examiner-blind study. After screening and stratification by sex and papillary bleeding index (PBI), participants were randomly and equally assigned to four groups: (1) toothbrushing + rinsing (0.06% CHX + 0.025% NaF, alcohol-containing rinse, Corsodyl® Daily Defence Mouthwash; positive control); (2) toothbrushing + rinsing (0.06% CHX + 0.025% NaF, alcohol-free experimental rinse); (3) toothbrushing + rinsing (0.06% CHX + 0.03% CPC + 0.025% NaF, alcohol-free experimental rinse); (4) toothbrushing alone (negative control). At baseline, Quigley-Hein plaque index (QHI), the modified proximal plaque index (MPPI), and PBI were recorded. All subjects were advised to brush their teeth as usual during the eight weeks study period. Additionally, groups 1-3 were instructed to rinse twice daily (30 sec. each). All participants used Dr. Best multi aktiv toothpaste and Dr. Best plus toothbrush (medium stiffness). Eight weeks after baseline, indices were recorded again. Anova with Bonferroni adjustment was used for statistical analysis.
Influence of Smoking on Clinical, Microbiological and Immunologic Parameters in Patients With Aggressive...
Periodontal DiseasesAggressive PeriodontitisTreatment of smoker patients with AgP is considered a challenge to periodontists. To date, only one controlled clinical study (De Genaro Modanese et al., 2016) evaluated the effect of full mouth ultrasonic debridment (FMUD) on smokers with aggressive periodontitis. Its results showed significant improvements in clinical parameters (plaque index PI, bleeding on probing- BoP and probing depth-PD), and immunologic (reductions in interleukin 6- IL-6, tumor necrosis factor- α TNF-α levels), although the results were more favorable for non-smoking patients. Antimicrobials associated to mechanical therapy has been extensively studied (Hafajee et al., 2003, Heitz-Mayfield, 2006). The association of Amoxicillin and Metronidazole have had good clinical and microbiological results in randomized clinical trials in the treatment of AgP (Casarin et al., 2012, Sgolastra et al., 2012, Keestra et al., 2015). Thus, this study investigates clinical, microbiological and immunological influence of smoking in the periodontal debridement associated to Amoxiciclin and Metronidazole of young individuals with pronounced periodontal destruction, compared with non-smokers individuals.

The Effects of Subgingival Air-polishing, as an Adjunct to Non-surgical Periodontal Treatment on...
Periodontal DiseasesPeriodontal disease is serious and global chronic disease. The prevalence of periodontal diseases in United Arab Emirates is not clear but data from Dubai Health Authority showed that one in five patients has received periodontal treatment in recent years. Several studies reported the additional benefits provided by the use of air-polishing devices in combination with ultrasonic debridement in the treatment of gum disease, their use may reduce postoperative pain and discomfort while providing improvement in gum status. The aim of the study is to compare the effect of removing bacterial deposit (biofilm) from deep tooth pocket using combined air-polishing and conventional pocket debridement versus conventional pocket debridement alone on tooth supporting tissue parameters in patients with advanced gum disease (periodontitis). Methodology: A total of 22 patients with advanced gum disease will be randomly allocated to two groups: a control group, which will receive conventional pocket debridement and a test group which will receive ultrasonic debridement with air-polishing (Airflow Prophylaxis Master, EMS, Nyon, Switzerland). Gum measurements will be recorded by a masked calibrated examiner at six points for each tooth and patients' postoperative experience and satisfaction will be assessed using special forms.
