An in vitro evaluation of efficacy of ViaSpan, aloe vera, gatorade solution, and propolis storage media for maintaining the periodontal ligament cell viability.

Background: Replantation is a commonly performed method for avulsed tooth. A vital periodontal membrane (periodontal ligament [PDL]) is significant for the successful healing of replanted teeth. Hence, various storage media are used to preserve the viability of periodontal cells before replantation. Objectives: The present study was conducted to evaluate the efficacy of ViaSpan, Aloe vera, Gatorade solution, and propolis storage media for maintaining the PDL cell viability. Materials and Methods: The present study was conducted on 40 recently extracted teeth which were randomly divided into four study storage groups: Group I: ViaSpan, Group II: Aloe vera, Group III: Gatorade solution, and Group IV: Propolis. Later they were subjected to centrifugation, and the cells from supernatant were colored with 0.4% trypan blue for determination of viability. The obtained data were statistically evaluated with SPSS package (21.0 version, Inc.; Chicago, IL, USA) using analysis of variance, Mann-Whitney test, and Post hoc tests. Results: The mean viable periodontal cell in Group I was 30.2 cumm, in Group II was 24.6 cumm, Group III was 14.5 cumm, and Group IV in 31.4. The difference was significant (P < 0.01). Post hoc test between different groups revealed a significant difference in mean viable periodontal cells (P < 0.001). Propolis, ViaSpan, and Aloe vera had higher pH and osmolality values. Conclusion: This study found that propolis had higher periodontal cell viability followed by ViaSpan solution and Aloe vera and least in Gatorade solution. Propolis, ViaSpan, and Aloe vera media can be used as a storage media.

Résumé Contexte: la Replantation est une méthode couramment utilisée pour la dent avulsée. Une membrane parodontale vitale (ligament parodontal [PDL]) est important pour la guérison réussie des dents replantées. Par conséquent, divers supports de stockage sont utilisés pour préserver la viabilité du parodontal les cellules avant la réimplantation. Objectifs: la présente étude a été menée pour évaluer L'efficacité de ViaSpan, Aloe vera, solution de Gatorade, et des supports de stockage de propolis pour maintenir la viabilité des cellules PDL. Matériaux et Méthodes: la présente étude a été menée sur 40 récemment dents extraites qui ont été divisées au hasard en quatre groupes de stockage d'étude: Groupe I: ViaSpan, Groupe II: aloe vera, Groupe III: Gatorade solution, et groupe IV: Propolis. Plus tard, ils ont été soumis à une centrifugation et les cellules du surnageant ont été colorées avec 0,4% de trypan bleu pour la détermination de la viabilité. Les données obtenues ont été évaluées statistiquement avec le package SPSS (version 21.0, Inc. Chicago, ILLINOIS, états-unis) en utilisant l'analyse de la variance, le test de Mann-Whitney et les tests post hoc. Résultats: la cellule parodontale viable moyenne dans le Groupe I était de 30,2 cumm, dans Le groupe II était de 24,6 cumm, le Groupe III de 14,5 cumm et le Groupe IV de 31,4. La différence était significative (P < 0,01). Essai post hoc entre différents groupes ont révélé une différence significative dans les cellules parodontales viables moyennes (P < 0,001). Propolis, ViaSpan et aloe vera avaient plus valeurs de pH et d'osmolalité. Conclusion: Cette étude a révélé que la propolis avait une viabilité cellulaire parodontale plus élevée suivie D'une solution de ViaSpan et Aloe vera et moins dans la solution de Gatorade. La Propolis, le ViaSpan et L'aloe vera peuvent être utilisés comme support de stockage. Mots-clés: aloe vera, Gatorade, cellules parodontales, propolis, ViaSpan.

Efficacy evaluation of rubber cup and air polishing techniques using glycine in plaque and stain removal - A clinical trial.

BACKGROUND: Researchers have proved Glycine to be safe, less abrasive, sweet and comfortable for patients. It is beneficial in removing plaque as well as stains. The present study aims to compare the plaque and extrinsic stain removal efficacy of the air-polishing device and rubber cup prophylaxis technique along with a comparative evaluation of the gingival trauma caused by both the techniques. METHOD: This split-mouth randomized clinical trial was conducted on a total of 60 subjects in half of whom, left side was assigned to Glycine powder air polishing and the right side to rubber cup prophylaxis with (Glycine powder) and vice versa in the other half. All the subjects had their calculus removed one month prior to the intervention. Plaque index, Stain index and Trauma index were recorded and statistical analysis was done. RESULTS: Both the techniques (RCP and AP) demonstrated a significant reduction in plaque and stains within their respective groups, but revealed non-significant differences between the study groups. Gingival trauma was found to be significantly higher in case of AP group. Rubber cup technique was preferred over air polishing by the subjects. CONCLUSION: The data indicates that both the techniques were equally beneficial for plaque and stain removal, but rubber cup polishing technique has an advantage over the air polishing technique.

Linking periodontal disease with obesity and blood glucose.

It is of interest to evaluate the association of obesity and blood glucose level with periodontitis. Patients (150 with age range 26-68 years) were included based on WHO obesity criteria, undiagnosed for periodontitis, with Body Mass Index (BMI) ≥ 30 and systemically healthy. These patients underwent periodontal examination followed by blood analysis for lipid profile and blood sugar level. The periodontal status was determined using parameters such as Plaque index (PI), gingival index (GI), Probing depth (PPD) and Clinical attachment loss (CAL). 103 (68.7%) patients had >190 of triglyceride values. Data shows that periodontitis has no statistical significance with total cholesterol, HDL, LDL and moderate significance with VLDL, triglycerides. Glycemic control of the patients is assessed using postprandial blood sugar (PPBS) and Fasting Blood Sugar (FBS). Data shows that 129(86.6%) had FBS (mg/dl) <100 and 21 (14.0%) had FBS (mg/dl) >100. So the number of patients with FBS (mg/dl) < 100 were more i.e., 129 (86.6%). The PPBS values were in 136 (90.7%) had PPBS (mg/dl) <140 and only 14(9.3%) had PPBS (mg/dl) >140 group of patients were said have glucose intolerance. Thus, there is no change in lipid profile with established periodontitis in obese individuals. However, altered glycemic control is observed.
