Background: A large number of trials has been conducted using curcumin as the main ingredient in mouth rinses, topical oral gel, subgingival irrigant, locally delivered gel and locally delivered chips to reduce gingival inflammation and probing pocket depth. However, the results of these trials vary and are debatable. Objective: To evaluate the effectiveness of oral curcumin products as compared to the routinely used ones in reducing gingival inflammation and probing pocket depth in adults. Methods: Electronic databases such as Pubmed/Medline and Cochrane Library and hand searching was done for randomised controlled trials (RCTs), which yielded 148 results, of which 27 RCTs compared curcumin products with routinely used ones. Meta-analysis was conducted to check for plaque reduction, gingival inflammation and pocket depth. Results: 963 participants in the 27 RCT studies were considered for a systematic review. We found that for a long-term evaluation of probing pocket depth in nine studies each with 400 participants, there was a statistically significant difference in the reduction when curcumin topical gel was used as compared with the control [SMD −0.87, 95% CI: −1.31 to −0.43]. However, in the evaluation of short-term plaque and gingival scores, we found no statistically significant differences in the reduction when curcumin mouth rinse was used [SMD −0.76, 95% CI: −2.25 to 0.73] and [MD: −0.09, 95% CI: −0.29 to 0.10]. Conclusion: Curcumin topical and local delivery gel, mouth rinses and sub-gingival irrigants were found to be equally effective compared to the routinely used agents for reduction of plaque and gingival inflammation. Curcumin local delivery gel had greater reduction in probing pocket depth.

Background: Membrane-organizing extension spike protein (Moesin) is a cytoskeletal protein expressed in the gingival crevicular fluid (GCF) which may play a role in the immune response in periodontal disease. The objective of this study was to evaluate whether Moesin can be used as a biomarker for periodontal disease. Materials and Methods: Thirty patients satisfying the required inclusion criteria were selected from those reporting to the out patient (OP) of the department of periodontics and divided into two groups: Group A – systemically healthy controls with no periodontitis and Group B – systemically healthy controls with chronic severe periodontitis. Periodontal parameters were recorded. GCF was collected, and Moesin levels in the two groups were assessed using enzyme-linked immunosorbent assay. Scaling and root planing (SRP) was done in Group B patients who were reviewed, and samples were collected again after 4 weeks and analyzed. Results: At baseline, the mean GCF Moesin level in Group A was 666.95 ± 471.872 pg/ml, while in Group B, it was found to be 27435.35 ± 14179.77 pg/ml, which showed a high statistically significant difference on comparison. The mean GCF Moesin level in patients with chronic severe periodontitis was 27435.35 ± 14179.77 pg/ml at baseline, and on review 1 month after SRP, it was found to have undergone a statistically significant reduction to 27161.23 ± 14161.57 pg/ml (P = 0.001). Conclusion: Within the limits of this study, it can be concluded that Moesin can serve as a potential biomarker for periodontal disease.

Introduction: Periodontal diseases are caused by pathogenic bacteria locally colonized in the dental biofilm creating infection; the main etiological factor is represented by dental plaque and in particular by anaerobic Gram-negative bacilli. For that reason, the first phase of periodontal treatment is always represented by the initial preparation which primarily aims at the elimination or reduction of bacterial infection and the control of periodontal plaque-associated inflammation. Yet, another innovative causal therapy is represented by the irradiation of periodontal pockets with LASER. The aim of this randomized clinical study is to compare and to detect the presence of periodontal pathogens in chronic periodontitis patients after nonsurgical periodontal therapy with and without diode LASER disinfection using BANA test. Materials and Methods: This randomized clinical trial includes 20 patients having chronic periodontitis. From each patient, one test site and one control site were selected and assessed for gingival index (GI), oral hygiene index (OHI), pocket probing depth and clinical attachment level (CAL), and presence of BANA pathogens. The test site underwent scaling and root planning along with diode LASER therapy as an adjuvant while the control site received scaling and root planning alone. Patients were recalled for review after 2 weeks and 2 months where periodontal parameters were assessed and plaque samples were collected and analyzed for BANA pathogens. Results: The test site where LASER was used as an adjuvant showed significant reduction in pocket probing depth, CAL, OHI, GI, and periodontal pathogens which shows that the amount of recolonization of microbes is less when LASER is used as an adjuvant to conventional therapy. Conclusion: Diode LASER as an adjuvant to SRP has shown additional benefits over conventional therapy in all the clinical parameters evaluated and this can be associated in the treatment of periodontal therapy. BANA-enzymatic kit is a simple chair side kit which can be reliable indicator of BANA positive species in dental plaque.

Background: There is definite evidence for the involvement of retina in Parkinson's disease (PD). However, a specific pattern has not been clear due to the cross-sectional nature of the majority of the previous studies.Objective: The aim of this work was to study the pattern of changes in the retinal layers in patients with PD on longitudinal follow-up.Materials and Methods: Twelve patients with PD (23 eyes) were evaluated at baseline with complete history, clinical examination, Unified Parkinson's Disease Rating Scale (UPDRS) motor part, visual acuity, and retinal imaging with spectral-domain Optical Coherence Tomography. After a mean duration of 3.7 ± 0.46 years, patients were re-evaluated.Results: The Central Macular Thickness (CMT) of the right eye was found to be significantly thicker during the follow-up (P = 0.002). The outer retinal layer in the temporal quadrant at 0.5 centimeters from the fovea of the left eye was found to be significantly thinner (P = 0.001).Conclusion: The serial evaluation of the retinal layers in patients with PD suggests a progressive loss of thickness of the outer retinal layer. The involvement of non-dopaminergic mechanisms, especially glutamatergic pathways, may be responsible for these changes. [ABSTRACT FROM AUTHOR]

Background: Wilson's disease (WD) is an autosomal recessive disorder of copper metabolism. We aimed to study the abnormalities in the retinal layers in patients with WD using optical coherence tomography (OCT). Methods: The study is a chart review of 16 patients with WD (six females) who underwent OCT at our hospital during follow-up visits. Spectral-domain OCT was performed in all subjects to assess the thickness of macula and retinal nerve fiber layer (RNFL) and the data was compared with 14 healthy controls (three females). Results: The mean age of the patients was 20.81 ± 7.47 years and controls was 26.86 ± 9.95 years. The mean age at the onset of the illness was 16.25 ± 5.57 years (range 11–28 years) with the mean duration of illness being 4.81 ± 3.31 years at the final follow-up examination. The mean macular thickness was found to be significantly reduced in patients (232.13 ± 19.39) when compared to controls (271.30 ± 17.32 μm; P = 0.01). There was a significant difference in the ganglion cell and inner plexiform (GCIP) layer between the patients (86.83 ± 8.20 μm) and controls (97.72 ± 5.31 μm; P = 0.01). In addition, the outer nuclear layer with the photoreceptor layer (ONL + PRL) thickness was also reduced in WD (93.90 ± 10.23 μm vs. 108.43 ± 10.00 μm; P = 0.01) There was no change in the RNFL thickness, between the two groups (P = 0.53). Conclusions: Abnormalities of the retinal layers were observed in the patients with WD. OCT is a non-invasive tool to identify and quantify the abnormalities of the retinal layers.
