24 composite inlays, which were thoroughly documented for postgraduate education purposes were recalled after 13.3 and 30.5 months on average. The clinical evaluation yielded very good results after 13.3 and good results after 30.5 months, respectively. Marginal gaps were observed in 6.6% at the tooth-composite cement and in 27.1% at the composite cement-inlay-interface after 13.3 months using replica technique and SEM. There values were not significantly different from the findings at 30.5 months. The adhesive failures between inlay and composite cement were preferably located in large, multisurfaced restorations. No significant differences were found between direct immediate inlays and lab-made indirect inlays and between molar and premolar restorations, respectively.

UI	MeSH Term	Description	Entries
D007284	Inlays	Restorations of metal, porcelain, or plastic made to fit a cavity preparation, then cemented into the tooth. Onlays are restorations which fit into cavity preparations and overlay the occlusal surface of a tooth or teeth. Onlays are retained by frictional or mechanical factors.

D008855	Microscopy, Electron, Scanning	Microscopy in which the object is examined directly by an electron beam scanning the specimen point-by-point. The image is constructed by detecting the products of specimen interactions that are projected above the plane of the sample, such as backscattered electrons. Although SCANNING TRANSMISSION ELECTRON MICROSCOPY also scans the specimen point by point with the electron beam, the image is constructed by detecting the electrons, or their interaction products that are transmitted through the sample plane, so that is a form of TRANSMISSION ELECTRON MICROSCOPY.

D018709	Statistics, Nonparametric	A class of statistical methods applicable to a large set of probability distributions used to test for correlation, location, independence, etc. In most nonparametric statistical tests, the original scores or observations are replaced by another variable containing less information. An important class of nonparametric tests employs the ordinal properties of the data. Another class of tests uses information about whether an observation is above or below some fixed value such as the median, and a third class is based on the frequency of the occurrence of runs in the data.
