MATERIALS AND METHODS: In this cross-sectional study conducted over a 3-month period at a primary dental clinic in Malaysia, 45 participants were recruited via consecutive sampling and assigned into three groups, namely healthy periodontium group (n = 15), gingivitis group (n = 15), and periodontitis group (n = 15). Gingival crevicular fluid and plasma samples were collected from each participant. Enzyme-linked immunosorbent assay test was conducted to measure the concentration of IL-10, IL-17, IL-27, IL-35, and IL-37. Kruskal-Wallis H test was used to compare the interleukin levels between patient groups.
RESULTS: In GCF samples, IL-17 level was the highest in the periodontitis group (p <0.05), while IL-27 was the lowest (p <0.05). Meanwhile, plasma levels of IL-27 and IL-37 were significantly lower (p <0.05) in the periodontitis group, but plasma IL-35 levels were observed to rise with increasing disease severity.
CONCLUSION: There are reduced local and systemic levels of IL-27 in periodontitis patients.
CLINICAL SIGNIFICANCE: Periodontal diseases exert both local and systemic effects, resulting in the destruction of the tooth-supporting structures and contributing to the systemic inflammatory burden. Some of the cytokines that were investigated in the current study, IL-17, IL-27, IL-35, and IL-37, can be potential biomarkers that warrant further longitudinal clinical studies to determine their usefulness as prognostic/diagnostic markers.
MATERIALS AND METHODS: A cross-sectional study was performed and a 13-item survey questionnaire was given to FMPs practicing in 12 different teaching hospitals in Karachi, Pakistan. The questions were aimed at exploring the knowledge of FMP's regarding the association of obesity and periodontal disease and their attitude towards the association of obesity and periodontal disease. Chi-square and Spearman co-efficient were conducted to compare subgroups and correlate factors with the knowledge score of FMPs.
RESULTS: A total of 314 questionnaires were completed (response rate = 92%). Median age of participants was 41 years and 57% were females. Almost 61% of FMPs answered all the knowledge questions correctly and 64% reported moderate understanding of the association between periodontal health and obesity. Nearly 73% FMPs inquired from obese patients regarding the periodontal disease and more than half (58%) refer patients to a dentist for evaluation. More than half of FMPs perform periodontal disease screening. Nearly all FMPs considered informing obese patients regarding periodontal disease as one of their roles.
CONCLUSIONS: FMP's play an important role in the early diagnosis, prevention and treatment of periodontal conditions in obese patients. More than two thirds of FMPs showed good knowledge of the association of obesity and periodontal disease. The attitudes of FMPs towards assessing and referring obese patients at a risk of having periodontal disease were reassuring.
MATERIALS AND METHODS: This longitudinal study included 2198 participants with mean age 43.4 ± 7.7 years, who underwent dental examinations in Yokohama, Japan, at two time points, 2003-2004 and 2008-2009, at an interval of 5 years. Periodontal condition was assessed by the mean value of probing pocket depth (PPD) and clinical attachment level (CAL). Glycaemic status was assessed by fasting glucose and glycated haemoglobin (HbA1c).
RESULTS: The cross-lagged panel models showed the effect of HbA1c at baseline on mean PPD at follow-up (β = 0.044, p = .039). There was a marginal effect of fasting glucose on the mean PPD (β = 0.037, p = .059). It was similar to the effect of fasting glucose or HbAlc on mean CAL. However, in the opposite direction, no effect of mean PPD or CAL at baseline on fasting glucose or HbAlc at follow-up was identified.
CONCLUSIONS: This study demonstrated a unidirectional relationship between glycaemic status and periodontal condition. The study population, however, had mostly mild periodontitis. Future studies are needed to investigate the effect of periodontal condition on glycaemic status in patients with severe periodontitis.
METHODS: The Pub med data base was searched for human clinical studies, reviews pertinent to application of green tea polyphenols in periodontal health dating from Sep 1980- Sep 2014.
RESULTS: The retrieved inference from the epidemiological surveys, in vitro studies and overviews of polyphenols, postulate green tea as potential natural antioxidant. Green tea mouthwashes possess limitations, which make them ineffective during the chronic stages of periodontitis. Human studies reveal that the prognosis of periodontal disease is better when the green tea catechins are used via local drug delivery.
CONCLUSION: The maintenance of periodontal health could be enhanced by emphasizing the habit of drinking green tea in periodontitis patients. The future scope of the research demands the analysis of polyphenols at molecular level to have a better understanding of its overwhelming applications.
METHODS: This cross-sectional study had randomly and systematically recruited facial burn patients from the Burn Care Center, Pakistan Institute of Medical Sciences, Islamabad, from June of 2016 to July of 2017. Intraoral examination recorded the DMFT, CPI and OHI-S. Information on the socio-demographic status, self-perceived oral health, oral health behaviours were collected using a self-administered questionnaire and; the burn characteristics were obtained from the patients' medical record. The t-test, ANOVA, SLR, and chi-square test were used to examine the relationship between oral health and each factor. A parameter was derived from the clinical indices using the principal component analysis and used in the multiple linear regression analysis to determine the important factors associated with oral health status.
RESULTS: A total of 271 burn patients (69% female and 31% male) had participated in the study. All of the participants had caries with mean DMFT = 10.96 (95%CI: 10.67, 11.25). There were 59.0% (95%CI: 53.15, 64.93%) and 66.1% (95%CI: 60.38, 71.73%) of the participants who had periodontitis and poor oral hygiene respectively. About 79 and 80% of the participants rated their dental and periodontal status as poor. About 78% reported brushing once daily and 89% did not practice regular dental visit. The DMFT, CPI and OHI-S were associated with the burn characteristics and oral health behaviours (p
