RESUMO
ABSTRACT: Despite the reported effects of smokeless tobacco (ST) on the periodontium and high prevalence of ST use in rural populations and in males studies on this specific topic are limited. The purpose of this cross-sectional investigation was to measure lipid peroxidation (as an end product of oxidative stress) end product i.e. Malondialdehyde (MDA) in saliva of patients with gingivitis, chronic periodontitis and to assess the influence of smokeless tobacco on Salivary Malondialdehyde (S-MDA). Total 30 patients with gingivitis, 30 with chronic periodontitis and 30 Smokeless Tobacco Chewers with Chronic Periodontitis and 30 periodontally healthy subjects were included in the study. Plaque Index (PI), Gingival Index (GI), Probing Pocket Depth (PD), and Clinical Attachment Loss (CAL) were recorded followed by stimulated Saliva sample collection. Salivary MDA Levels were assessed by UV Spectrophotometry. There was a statistically significant increase in the salivary MDA levels in gingivitis, chronic periodontitis and in smokeless tobacco chewers with chronic periodontitis when compared with healthy group. Higher salivary MDA levels in gingivitis group, chronic periodontitis, and smokeless tobacco chewers with chronic periodontitis reflects increasedoxygen radical activity during periodontal inflammation.
RESUMEN: A pesar de los efectos reportados del tabaco sin humo (TS) sobre el periodonto y la alta prevalencia del uso de TS en poblaciones rurales y en hombres, los estudios sobre este tema específico son limitados. El propósito de esta investigación transversal fue medir el producto final de la peroxidación lipídica (como producto final del estrés oxidativo), es decir, malondialdehído (MDA) en la saliva de pacientes con gingivitis, periodontitis crónica y evaluar la influencia del tabaco sin humo en el malondialdehído salival (S-MDA). Se incluyeron en el estudio un total de 30 pacientes con gingivitis, 30 con periodontitis crónica y 30 masticadores de tabaco sin humo con periodontitis crónica y 30 sujetos periodontalmente sanos. Se registraron el índice de placa (PI), el índice gingival (GI), la profundidad de la bolsa de sondeo (PD) y la pérdida de adherencia clínica (CAL), seguidos de la recogida de muestras de saliva estimuladas. Los niveles de MDA en saliva se evaluaron mediante espectrofotometría UV. Hubo un aumento estadísticamente significativo en los niveles de MDA en saliva en gingivitis, periodontitis crónica y en masticadores de tabaco sin humo con periodontitis crónica en comparación con el grupo sano. Los niveles más altos de MDA en saliva en el grupo de gingivitis, periodontitis crónica y masticadores de tabaco sin humo con periodontitis crónica reflejan un aumento de la actividad de los radicales de oxígeno durante la inflamación periodontal.

BACKGROUND: It has been long recognized that periodontal diseases are infections of the periodontium, comprising the bacterial etiology, an immune response, and tissue destruction. Treatment strategies aiming primarily at suppressing or eliminating specific periodontal pathogens include adjunct use of local and systemic antibiotics as part of nonsurgical periodontal therapy. Unwanted side effects and resistance of microorganisms toward antibiotics due to their widespread use have modified the general perception about their efficacy. Research in phytosciences has revealed various medicinal plants offering a new choice of optional antimicrobial therapy. Cymbopogon citratus, Stapf. (lemongrass) is a popular medicinal plant. At a concentration ≤2%, lemongrass essential oil inhibits the growth of several kinds of microorganisms including periodontal pathogens, especially the reference strains Actinomyces naeslundii and Porphyromonas gingivalis, which were resistant to tetracycline hydrochloride. AIMS: To evaluate the efficacy of locally delivered 2% lemongrass essential oil in gel form as an adjunct to scaling and root planing, as compared to scaling and root planing alone for the treatment of chronic periodontitis. MATERIALS AND METHODS: 2% Lemongrass essential oil gel was prepared and placed in moderate to deep periodontal pockets after scaling and root planing. RESULTS: Statistically significant reduction in probing depth and gingival index and gain in relative attachment level were noted in the experimental group as compared to the control group at 1 and 3 months. CONCLUSION: Locally delivered 2% lemongrass essential oil gel offers a new choice of safe and effective adjunct to scaling and root planing in periodontal therapy.
