Antibacterial activity of extracts of Allium sativum (garlic), Myristica fragrans (nutmeg), Zingiber officinale (ginger), Allium cepa (onion) and Piper nigrum (pepper) has been evaluated against 20 different serogroups of Escherichia coli, 8 serotypes of Salmonella, Listeria monocytogenes and Aeromonas hydrophila. Garlic extract showed excellent antibacterial activity against all the test organisms, except L. monocytogenes. Nutmeg showed good anti-listerial activity, although activity against E. coli and Salmonella were serotype dependent. Both garlic and nutmeg extracts were effective against A. hydrophila. Extracts of ginger showed inhibitory activity against two serogroups of E. coli: as O8 (enterotoxigenic E. coli) and O88 only. Extracts of onion and pepper did not show any antibacterial activity against the test organisms.

Background and Objectives:Coenzyme Q10 is a well-studied antioxidant in the medical literature, but studies regarding its efficacy in periodontal diseases are few. coenzymeoenzyme Q10 serves as an endogenous antioxidant and its increased concentration in the diseased gingiva effectively suppresses advanced periodontal inflammation. The aim of this study is to evaluate the efficacy of coenzyme Q10 (Perio Q™) as an adjunct to scaling and root planing in patients with chronic periodontitis.Materials and Methods:A total of 18 patients were enrolled for the study. The selected subjects were treated in three different quadrants randomly. The control quadrant was treated by scaling and root planing only, while the other two test quadrants were treated by intra-pocket application of gel combined with scaling or root planing and topical applications combined with scaling and root planning, respectively. Clinical parameters such as plaque index, gingival index, gingival bleeding index and probing pocket depth were assessed at baseline and at the 2nd week and 4th weeks. The results were subjected to statistical analysis.Results:There was a significant improvement in all clinical parameters in the test sites seen at the end of the 4-week period. Sites with bleeding on probing were reduced more in the test group than in the control group.Conclusion:Coenzyme Q10 can be said to have a beneficial effect on periodontitis when used as an adjunct to scaling and root planing.

Background:The present study was designed to evaluate clinical and antimicrobial effects of a single episode of subgingival tetracycline or chlorhexidine (CHX) irrigation in the absence of scaling and root planing.Materials and Methods:Thirty patients diagnosed with chronic periodontitis were recruited for this study, each providing four non-adjacent untreated periodontal pockets with a probing depth equal to or exceeding 6 mm. The four deep periodontal pockets in each patient were assigned to be irrigated with 150 ml each of CHX digluconate 0.2% (group A), tetracycline HCl at concentrations of 10 and 50 mg/ml (groups B and C, respectively), or sterile saline (group D) in a single episode. Recordings of plaque index (PI), gingival index (GI), probing pocket depth (PD), clinical attachment level (CAL), and subgingival bacterial counts from paper point samples were made pre-irrigation (day 0), and at days 7, 28, 56, and 84, post-irrigation.Results:The mean PI and GI scores for all the four groups were reduced post-irrigation, the reduction being significantly higher in group C compared to the other groups. The reduction in the PD and CAL was more significant in group C from day 0 to day 7, whereas the other groups showed minimal changes during this period. The change in the bacterial count was altered towards one of the periodontal health, it being more significant and consistent in the group C.Conclusion:The results of this study suggest that subgingival irrigation with high concentrations of tetracycline may play a beneficial role in the management of chronic periodontitis patients.

Background Periodontal disease is a chronic inflammatory condition of multifactorial origin. The inflammatory mediators released during the progression of disease may affect all the organs of the body. Renal disease is a chronic systemic disease which may influence the progression of periodontal disease. Therefore, this study was conducted to evaluate and compare the prevalence of periodontal disease among individuals with chronic kidney disease undergoing maintenance hemodialysis with healthy individuals. Methodology In this cross-sectional study including 150 participants, 75 patients with different renal diseases undergoing hemodialysis (Group I) and 75 healthy controls (Group II) were included. The general examination of the patients was done. Blood pressure, pulse, and body mass index were recorded, followed by biochemical investigations, in which serum urea, serum creatinine, and random blood sugar were evaluated for each participant. Plaque Index (PI) and Gingival Index (GI) scores were recorded. Probing pocket depth (PPD) and gingival recession GR were measured, and clinical attachment level (CAL) was calculated based on the obtained values. The subjects were then categorized into three groups, namely, no/mild, moderate, and severe periodontitis. Results Out of the total study participants, 68% were men and 32% were women, with a mean age of 47 years. Serum markers were significantly elevated in Group I compared to Group II. Poor oral hygiene and periodontitis were observed to be much higher in dialysis patients compared to the control group. The two groups also significantly differed in PI, GI, PPD, GR, and CAL, all of which were higher in Group I. Conclusions The results suggest that patients with renal disease must be screened for periodontal disease.

Guava leaves extract can be used as economical and suitable adjuvant to synthetic drugs and can be a potential therapeutic agent for periodontitis.
