<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:
