Antibacterial Effects of Several Current Orthodontic Materials against Streptococcus mutans

KAMAK, HASAN/0000-0003-1910-3694WOS: 000322424100010PubMed: 23757904The aim of this study was to examine the antibacterial effect of several current orthodontic materials against a certain oral bacterium. The antibacterial activities of six orthodontic composite resins (Transbond LR, Light Cure Retainer (LCR), Light Bond, System 1+, Kurasper E Transbond XT adhesive), two orthodontic bonding materials (Transbond XT primer and System 1+ activator) and two glass ionomer cements (GIC) [Multicure Glass Ionomer and Ketac Cem WC] were evaluated against Streptococcus mutans. The hard materials were put into the Teflon mould. The liquid materials were put on a paper disc. All materials were handled under aseptic conditions and placed on agar culture plates. All plates were incubated at 5% CO2 and 37 degrees C for 48 hours. The bacterial growth inhibition zones including the diameter of the sample were measured in millimetres. As a result of this study, the multicure GIC showed the highest antibacterial effectiveness, but no inhibition zones were noted for ketac cem GIC. The light bond adhesive of the Reliance orthodontic bonding system produced high antibacterial effect against S mutans, while the Reliance composite (LCR) did not show any antibacterial effect (p < 0.05). Both composite and primer of the transbond XT system demonstrated significant antibacterial effect against the test bacterium when compared to transbond LR (p < 0.05). Among the materials tested, kurasper F, Ormco system 1+ and system 1+ activator showed slight or no inhibitory effect against the test bacterium in this study. In patients who have relatively high salivary levels of Streptococci mutans before treatment, the multicure GIG, the Reliance light bond adhesive, and transbond XT system which had high level antibacterial properties could be applied

The prevalence of probable overactive bladder, associated risk factors and its effect on quality of life among Turkish midwifery students

PubMed ID: 22762841Objectives: To evaluate the associated risk factors of probable overactive bladder (OAB) and to determine the effect of OAB on quality of life through validated questionnaires in Turkish midwifery students. Study design: 279 midwifery students were invited to participate, and 265 (95.0%) were included in the study, which was approved by the local ethics committees. The relationship between quality of life and probable OAB was evaluated using Turkish language-validated questionnaires (OABq SF, NQOL). Chi-square test, t-test and logistic regression were used for the statistical analysis, and p < 0.05 was considered significant. Results: The participants' mean age was 21.74 ± 2.15 years. The prevalence of OAB was 35.4%. There was a significant relationship between the presence of probable OAB and familial urinary incontinence history and childhood nocturnal enuresis. In the logistic regression analysis, family history was associated with an OR of 2.11 (95% CI: 1.08-4.10) for OAB, and nocturia with an OR of 2.69 (95% CI: 1.16-6.21) for OAB. Drinking moderate amounts of tea and carbonated drinks daily did not affect OAB, but extreme consumption of these beverages was associated with an OR of 2.98 (95% CI: 1.26-7.03) for OAB. OAB significantly worsens quality of life according to all the quality of life indices. Conclusion: OAB is not a rare condition among young people. It appears that the quality of life was adversely influenced by OAB among both younger and older people. Familial urinary incontinence and childhood nocturnal enuresis were found to be risk factors for OAB. There is insufficient evidence to restrict tea or carbonated drinks consumption in young people with OAB unless their consumption is extreme. © 2012 Elsevier Ireland Ltd. All rights reserved
