  1. Relationship of periodontal disease and domains of oral health-related quality of life
    Masood M, Younis LT, Masood Y, Bakri NN, Christian B
    J Clin Periodontol, 2019 02;46(2):170-180.
    PMID: 30657192 DOI: 10.1111/jcpe.13072
    OBJECTIVES: The aim of this study was to investigate the impact of periodontal disease on the domains of oral health-related quality of life (OHRQoL) of United Kingdom adults.

    METHODS: National representative data from the 2009 Adult Dental Health Survey, United Kingdom, were used in this study. Periodontal disease severity was measured using periodontal pocket depth and categorized into three groups: pocket depth up to 3.5, 3.5-5.5 and more than 5.5 mm. OHRQoL was measured using the Oral Health Impact Profile-14 (OHIP-14) scores. Bivariate and multivariable Zero-inflated Poisson regression analysis was used.

    RESULTS: A total of 6378 participants was analysed in this study. Periodontal pocketing was significantly associated with higher OHIP-14 scores. Participants with periodontal pocket depths >3.5 mm had a significantly higher prevalence for functional limitation, physical pain and social disability than participants with pocket depths of less than 3.5 mm. Participants with periodontal pocket depth(s) >5.5 mm had significantly higher OFOVO prevalence in all the domains of OHIP-14 except handicap domain than participants with pocket depth(s) <3.5 mm.

    PARTICIPANTS:

    CONCLUSION: This study showed that for a nationally representative sample of the United Kingdom population, periodontal disease was significantly associated with the domains of OHRQoL.

  2. Within-family discussion on harmful effects of smoking and intention to initiate smoking among European adolescents
    Masood M, Masood Y, Md Sabri BA, Younis LT, Yusof N, Reidpath D, et al.
    J Addict Med, 2015 Jul-Aug;9(4):261-5.
    PMID: 26241085 DOI: 10.1097/ADM.0000000000000127
    OBJECTIVE: The main objective of this study was to determine the impact of discussion within family about the harmful effects of smoking on intention to initiate smoking in the long term among nonsmoking adolescents.
    METHODS: Data from Global Youth Tobacco Survey for 25 European countries were used. The outcomes of interest were, therefore, the intention to initiate smoking 1 and 5 years after the survey. Discussion within family about harmful effect of smoking was the main predictor with age, sex, and smoking status of parents, friends, and classmates as covariates. The association between predictors and outcomes was assessed through multiple regression analysis.
    RESULTS: A total of 118,703 nonsmoking adolescents were included. Within-family discussion significantly reduced the odds of intention to initiate smoking 1 and 5 years later. Intention to initiate smoking also was significantly associated with the smoking status of friends, classmates, and parents, except for father's smoking status, which was not associated with intention to initiate 1 year later.
    CONCLUSIONS: This study demonstrated that within-family discussion about the harmful effects of smoking may contribute to reduce the intention to start smoking among adolescents in the long term. Such a discussion was associated with reduced intention to smoke even when adjusting for parent/friend and classmate smoking.
  3. 3D TECA hydrogel reduces cellular senescence and enhances fibroblasts migration in wound healing
    Younis LT, Abu Hassan MI, Taiyeb Ali TB, Bustami TJ
    Asian J Pharm Sci, 2018 Jul;13(4):317-325.
    PMID: 32104405 DOI: 10.1016/j.ajps.2017.12.003
    This study was designed to investigate the effect of 3D TECA hydrogel on the inflammatory-induced senescence marker, and to assess the influence of the gel on the periodontal ligament fibroblasts (PDLFs) migration in wound healing in vitro. PDLFs were cultured with 20 ng/ml TNF-α to induce inflammation in the presence and absence of 50 µM 3D TECA gel for 14 d. The gel effect on the senescence maker secretory associated-β-galactosidase (SA-β-gal) activity was measured by a histochemical staining. Chromatin condensation and DNA synthesis of the cells were assessed by 4',6-diamidino-2-phenylindole and 5-ethynyl-2'-deoxyuridine fluorescent staining respectively. For evaluating fibroblasts migration, scratch wound healing assay and Pro-Plus Imaging software were used. The activity of senescence marker, SA-β-gal, was positive in the samples with TNF-α-induced inflammation. SA-β-gal percentage is suppressed (>65%, P
