fa In Vitro Effects of Four Porcelain Surface Treatment Methods on Adhesion of Lactobacilli Acidophilus بیماری های دهان Oral Medicine پژوهشي Research <p style="background-color: rgb(239, 243, 250)"><strong style="margin: 0px padding: 0px border: 0px"><i style="margin: 0px padding: 0px border: 0px">Objective: </i></strong>Adhesion of Lactobacillus acidophilus (L. acidophilus) to dental porcelain surface may lead to gingival inflammation and secondary caries. Surface roughness is among the factors affecting this adhesion. The purpose of this study was to evaluate the effects of four different surface treatment methods on adhesion of L. acidophilus to dental porcelain.</p><p style="background-color: rgb(239, 243, 250)"> <strong style="margin: 0px padding: 0px border: 0px"><i style="margin: 0px padding: 0px border: 0px"> Methods: </i></strong>Sixty specimens (3x10mm) were fabricated of Noritake porcelain and divided into 4 groups (n=15) treated with one of the following four surface finishing techniques: 1. Auto-glazing 2. Over-glazing 3. Polishing with Kenda kit and 4. No surface treatment (non-glazed specimens). Specimens were inoculated with bacterial suspension containing 1x10<sup style="margin: 0px padding: 0px border: 0px">6</sup>colony forming units per milliliter (CFU/mL) and L. acidophilus adhesion to the surfaces was evaluated using a spectrophotometer. Data were analyzed using one-way ANOVA and Tukey’s HSD test.</p><p style="background-color: rgb(239, 243, 250)"> <strong style="margin: 0px padding: 0px border: 0px"><i style="margin: 0px padding: 0px border: 0px"> Results: </i></strong>The mean bacterial adhesion was 0.1440 (0.00429) to auto-glazed specimens, 0.0750 (0.00256) to over-glazed specimens, 0.1800 (0.00325) to polished specimens and 0.7064 (0.00408) to the non-glazed specimens. The differences in this regard among groups were statistically significant (<i style="margin: 0px padding: 0px border: 0px">p</i><0.001).</p><p style="background-color: rgb(239, 243, 250)"> <strong style="margin: 0px padding: 0px border: 0px"><i style="margin: 0px padding: 0px border: 0px"> Conclusion: </i></strong>Over-glazed specimens caused the lowest and non-glazed specimens caused the highest bacterial adhesion. The glazed surfaces caused less adhesion than the polished surfaces.</p><hr><p class="MsoNormal" style="text-align: left direction: ltr unicode-bidi: embed"><b>Source: </b>Journal of Dental School Shahid Beheshti University of Medical Sciences </p> <p class="MsoNormal" style="text-align: left direction: ltr unicode-bidi: embed"><a href="http://jds.sbmu.ac.ir/browse.php?a_id=1406&sid=1&slc_lang=en" target="_blank"><font color="#0000ff">Full Text</font></a></p> Bacterial adhesion, Dental porcelain, Lactobacillus acidophilus, Surface treatment, 0 0 http://idai.ir/browse.php?a_code=A-10-32-2955&slc_lang=fa&sid=1 Shirin Lavaf 100319475328460013737 100319475328460013737 No Dept. of Prosthodontics, School of Dentistry, Islamic Azad University, Tehran, Iran Arash Azizi drarashazizi@yahoo.com 100319475328460013738 100319475328460013738 Yes Dept. of Oral Medicine, School of Dentistry, Islamic Azad University, Tehran, Iran Mohammad Rahbar 100319475328460013739 100319475328460013739 No Dept. of Microbiology, School of Medicine, Islamic Azad University, Tehran, Iran Amir Hossein Najafpour 100319475328460013740 100319475328460013740 No School of Dentistry, Islamic Azad University, Tehran, Iran Simin Rezaee Harzandi 100319475328460013741 100319475328460013741 No
