Assessment of Neopterin Levels in Pre- and Post-menopausal Women With Chronic Periodontitis

Menopause

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.

IL-32 Levels in Patients With Chronic Periodontitis

Periodontitis

Interleukin-32 (IL-32) is a recently described cytokine that is a strong inducer of pro-inflammatory cytokines such as tumor necrosis factor (TNF)-α. A previous report have reported that Porphyromonas gingivalis-derived LPS significantly up-regulated IL-32 expression compared with the unstimulated cells in monocytes (THP-1 cells). They suggested that IL-32 may contribute to the pathogenesis of periodontal disease. In the present study the investigators hypothesized that IL-32 levels may increase in the gingival crevicular fluid (GCF) and saliva of patients with chronic periodontitis compared with healthy controls and these levels may decrease together with treatment.

Efficacy of Turmeric in Gingival Massaging and Adjunct to Scaling and Root Planing in Chronic Periodontitis...

Chronic Periodontitis

Periodontal disease is considered as inflammatory, multifactorial, and threshold disease accompanied by destruction of periodontium and eventually the loss of natural teeth. Periodontal disease is highly prevalent dental disease especially, in developing and underdeveloped countries affecting more or less 80% of the population. For the prevention of this highly prevalent dental affliction, still no effective and practical preventive measures are available which can reduce its high prevalence rate though, lot of research work is going on.

Complex Phytoadaptogenes in Chronic Periodontitis Treatment.

Chronic Periodontitis

A randomized controlled clinical trial was done to assess the periodontal status of the individuals baseline followed by by including chronotherapy with complex phytoadaptogens (CFA) into the non-surgical periodontal treatment (NSPT). The periodontal parameters were again assessed after and compared with the control group (participants with healthy periodontium) and group with non-surgical periodontal treatment (NSPT).

Chronic Periodontitis (CP) Subjects.

Aim: To evaluate effect of non- surgical periodontal therapy on liver function in systemically healthy chronic periodontitis (CP) subjects. Materials and methods: The study is non surgical interventional trial, includes 50 CP subjects in the age group of 35- 60 years selected from the OPD (Out Patient Department) of department of periodontology Tatyasaheb Kore Dental College and Research center (TKDC and RC), Kolhapur. CP subjects were equally divided into test group and control group. Liver function test- aspartate aminotransferase (AST), alanine aminotransferase (ALT) were checked at baseline and at 1 month after treatment. Clinical examination includes plaque index, gingival index, sulcus bleeding index, probing depth, clinical attachment loss.

Changes of GCF Levels of RANKL and Osteoprotegerin in Postmenopausal Osteoporosis

Chronic Periodontitis

The investigators evaluated the effect of initial periodontal treatment on clinical findings and receptor activator of Nuclear Factor-kappa B ligand (RANKL) and osteoprotegerin (OPG) in gingival crevicular fluid (GCF) of patients with osteoporosis under bisphosphonate therapy within 12 months' follow-up. Clinical recordings and GCF were obtained from postmenopausal women; with chronic periodontitis and osteoporosis (Group A, n=13), with chronic periodontitis and no osteoporosis (Group B, n=12), without chronic periodontitis and osteoporosis (Group C, n=12), systemically and periodontally healthy controls (Group D, n=10) at the baseline. Recordings were repeated at the 1st, 6th and 12th months in Group A, B and C. RANKL and OPG values were measured by enzyme-linked immunosorbent assays.

Influence of Stress on Non Surgical Periodontal Treatment

Chronic Periodontitis

Treatment of periodontal diseases is influenced by several risk factors. Psychological stress is considered as one of them. Aim of this study is to assess if stress influences results of non surgical periodontal treatment in severe chronic forms of periodontitis.

The Link Between Periodontitis, Smoking and Oral Cancer

Chronic PeriodontitisOral Cancer

Periodontitis is a widely prevalent disease worldwide that has serious public health consequences. Its prognosis includes tooth loss and edentulism, a condition that negatively affects chewing causing functional disability; and esthetics causing social impairment. Consequently, periodontitis may end up causing marked impairment of the quality of life of the affected patients, impairment of general health and increasing the dental care costs significantly. Changes in the oral mucosa arise by primary products resulting from tissue breakdown due to gingivitis. It then triggers the host cells to produce proteinases that mediate loss of marginal periodontal ligaments, apical migration of the junctional epithelium and apical spread of bacterial biofilm. Therefore, this research aims to identify the risk of smoking to both periodontitis and oral cancer, and the risk of periodontitis to oral cancer.

Dose Parameters for Photodynamic Therapy on Periodontal Disease

Chronic Periodontitis

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.
