Supplementation With L-ornithine But Not L-arginine Increases Density of CD68+ and CD163+ Macrophages...
PeriodontitisThe aim of the study was to investigate whether oral administration of L-arginine or L-ornithine could modulate local representation density and ratio of macrophages in periodontitis-affected gingiva by using immunohistochemical detection of CD68+ and CD163+ macrophages in biopsies of the gingiva. The null hypothesis tested was that L-arginine and L-ornithine have no influences on CD68+ and CD163+ macrophages densities when supplementing the treatment of periodontitis. Materials and methods. 75 individuals with a diagnosis of generalized periodontitis at stages II-III and grade B (38 women and 37 men, 51% and 49%, respectively) were included in the study. Periodontitis was diagnosed by using the criteria of the Classification of Periodontal and Peri-Implant Diseases and Conditions 2017. 25 patients received scaling and root planing only; 25 patients additionally received L-arginine, and 25 - L-ornithine, according to instructions available in Ukraine. For the immunohistochemical study of paraffin-embedded sections, the gingival biopsy was taken from 5 selected patients per group before treatment and after 1 month. CD68+ (cluster of differentiation 68 positive) and CD163+ cells served as a morphological equivalent of M1, M2 macrophages subpopulations, and their densities were calculated per 10000 μm2. Statistical analysis was performed by adequate power methods.

Enamel Matrix Derivative in Non-surgical Periodontal Treatment
PeriodontitisThe aim of the study is to investigate the effect of enamel matrix derivative in addition to scaling and root planing in comparison to scaling and root planing only in periodontitis patients that have already undergone initial periodontal therapy and are in periodontal maintenance.

Hyaluronic Acid for Residual Periodontal Pockets Adjunctive Treatment
PeriodontitisObjective: To evaluate the adjunctive effect of hyaluronic acid (HA) gel in the treatment of residual periodontal pockets over a 12-month period. Materials and Methods: Periodontal patients enrolled in maintenance and presenting at least one periodontal pocket 5-9 mm of depth in the anterior area were recruited from six university-based centers. Each patient was randomly assigned to control treatment with professional mechanical plaque removal (PMPR) and local placebo application or test treatment with the adjunctive use of HA to PMPR. Clinical parameters [i.e. probing depth (PD), bleeding on probing (BoP), plaque score, recession (REC), and clinical attachment loss (CAL)] and microbiological samples for the investigation of the total bacterial count (TBC) and presence of specific bacterial strains (Porphyromonas gingivalis, Treponema denticola, Tannerella forsythia, Fusobacterium nucleatum) were taken at baseline and every 3 months, until study termination. PD was determined as the primary outcome variable.

Efficacy of Proanthocyanidins in Non-Surgical Periodontal Therapy
PeriodontitisAdultThe aim of the study is to evaluate the efficacy of proanthocyanidins as an adjunctive periodontal therapy in patients with periodontitis. Recently proanthocyanidins were proposed as a viable adjunct to periodontal treatment. Preclinical studies have shown high antibacterial and anti-inflammatory capacities of proanthocyanidins, that could reduce periodontal inflammation and promote periodontal tissues regeneration. In addition, proanthocyanidins demonstrate a specific antibacterial characteristic to attack periodonto-pathogenic bacteria (Porphyromonas gingivalis) but save the oral commensal bacteria (Streptococcus salivarius). Patients with periodontitis (stage III-IV) were included in this study. Patients with periodontitis received two different treatment modalities: minimally invasive non-surgical therapy only (MINST group) or minimally invasive non-surgical therapy and subgingival application of collagen hydrogels with proanthocyanidins (MINST+PACNs group). Clinical periodontal parameters (PPD, CAL, BOP, PI) were evaluated before treatment and after 8 weeks. Concentrations of immunological markers MMP-3 and TIMP-1 in saliva were investigated.

Curcumin Paste as an Adjunctive Therapy in Periodontitis
PeriodontitisThe turmeric (Curcuma longa) plant, a herb belonging to the ginger family. The most active component of turmeric is curcumin, which makes up 2 to 5% of the spice. Curcumin showed has antibacterial effect against periodontal pathogen and positive result regarding conventional treatment of periodontal disease due to its anti-inflammatory, anti-oxidant and wound healing properties. This study will be carried out to examine the effect of curcumin when used in conjunction with open flap debridement treating deep periodontal pockets. (suggesting that it may have positive effect)

The Effect of Non-surgical Periodontal Treatment in the Renal Function of Patients With Chronic...
Chronic Kidney DiseasePeriodontitisPeriodontal disease is a bacterially-induced inflammation. As such, it can become a point of entry of bacteria, toxins and cytokines into the systemic blood circulation, thus adversely affecting the function of kidneys. This is turn can aggravate the condition of patients with CKD. The study hypothesis is that periodontal therapy can improve renal function in patients with CKD and lower the blood levels of markers for systemic inflammation.

Adjunctive Antimicrobial Therapy of Periodontitis: Long-Term Effects on Disease Progression and...
PeriodontitisThe purpose of this study is to determine the size of the benefit of an adjunctive empiric antibiotic therapy compared to standard mechanical debridement and oral hygiene instructions in a representative sample of German periodontitis patients.

Treatment of Periodontitis Using Er:YAG Laser vs. Conventional Treatment Modalities
Chronic PeriodontitisConventional non-surgical periodontal treatment, that is, root debridement using manual and ultrasonic means at baseline and surgery using the same means after 6 months in case of persistent deep pockets (Group 1)/ Er:YAG laser used in a non-surgical approach at baseline and surgery using the same laser after 6 months in case of persistent deep pockets (Group 2)/ Surgery at baseline using manual and ultrasonic means (Group 3). All patients will undergo supragingival maintenance on a yearly basis.

Diabetes and Periodontal Therapy Trial
Chronic PeriodontitisType 2 DiabetesThe primary aim of the study is to determine if non-surgical periodontal therapy (scaling and root planing and supportive periodontal therapy) is efficacious compared to delayed therapy in reducing elevated glycosylated hemoglobin (HbA1c) at 6 months post-randomization in subjects with type 2 diabetes and untreated, moderate to advanced chronic periodontitis. The secondary aims of the study are to: evaluate whether 6 month (or shorter-term (3 month)) changes in clinical measures of chronic periodontitis (gingival index, bleeding on probing, probing depth, clinical attachment level) are related to changes in HbA1c and fasting glucose or insulin resistance as measured by the Homeostasis Model Assessment 2 (HOMA2). assess the 3 month and 6 month efficacy of periodontal therapy on all of the above study outcomes. If a treatment response is observed for any of the study outcomes at 3 months, then the trial can evaluate whether this response is sustained at 6 months.
