Mechanical Preparation of Samples For Profilometric Erosion Reserch
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2017, Vol 16, Issue 12
Abstract
ObjectivesThis research aims at determining the existence and the type of influence of the different mechanical sample preparations on the dental erosion research results. The research also includes the influence caused by the protection used to isolate parts of the sample surface. MethodsThis research involves fourteen dentin and fourteen enamel samples made of extracted intact human teeth, prepared mechanically in two different ways. We used lemon acid, as the erosion agent, diluted in artificial saliva in concentration of 0.1% with pH of 6.8. In addition, this research also analyzes the effectiveness of the fluoride preparations (a total of five different ones) on the progression of the previously caused erosion. The lemon acid and fluoride preparation treatment is cyclical, for a period of five days. For the purposes of this research, we protected parts of the sample surface using nail polish. The erosive surface changes were measured using the profilometer Surf test model No. SJ-410 (Mitutoyo make). ResultsThe changes to the sample surface conditions as a result of the influence from the lemon acid and the fluoride preparations were analyzed at a macro and micro level. The macro level analysis looked at the changes to the sample surface shape, and at the micro level it looked at the changes to the values of the roughness parameters Rz,Rp,Rv,Ra and RSm. The micro and macro level measurement results were processed and systematized graphically and in table form. We used the Analysis of Variance (ANOVA) method to statistically analyze the data. SignificanceThe results from the research showed that the sample mechanical preparation can significantly influence the dental erosion research results. The influence can be so significant as to suggest that casual mechanical preparation of the sample can lead to inaccurate conclusions regarding dental erosions.
