The study examined 6 recently extracted teeth in which were made cavities of average depth with different grains of diamond borers. Microslides were examined with an Electronic Scanning and Optic Microscope. 6 macroslides of the recently extracted teeth were made, using borers with different colored markings and studied with a 15X magnifying glass. The microslides showed that the minimal distance between composite and hard tissue is an average of 3.39 mcm, and that it is formed when preparing the cavities marked with yellow borrow diamante ring. The maximum distance, discovered when preparing cavities with the diamante borer marked with black, is 14.8 mcm. The macroslides, prepared with borers marked with white, yellow and red, show that the adhesive entirely covers the dental tissue, forming a smooth surface. |

În ei au fost preparate cavităţi cu o adâncime medie, folosind freze diamantinate, cu o mărime diferită a cristalelor. Cavităţile au fost obturate cu material compozit, respectând regulile necesare. După obturare, din dinţii incluşi în studiu au fost pregătite micropreparate, studiate apoi cu ajutorul microscopului electronic cu ambreiaj şi la nivel optic. De asemenea, au fost confecţionate 6 macropreparate a dinţilor recent extraşi, folosind freze cu mărime diferită de granulozitate. Piesele au fost studiate cu ajutorul lupei, ×15. Pe micropreparate s-a depistat că spaţiul minim dintre compozit şi ţesuturile dentare dure constituie în medie 3,93 mcm, şi se observă la prepararea cavităţilor cu freză diamantinată marcată cu inelul galben. Iar distanţa maximă se observă la prepararea cu freză marcată cu negru, şi constituie cca 15 mcm. Pe macropreparate s-a stabilit că, după prepararea cavităţilor cu freze marcate cu alb, galben şi roşu, adezivul acoperă complet rugozitatea formând o suprafaţă netedă.</p></dc:description> <dc:source>Curierul Medical 303 (3) 124-128</dc:source> <dc:subject>borer’s grain</dc:subject> <dc:subject>composite</dc:subject> <dc:subject>hard tissue</dc:subject> <dc:subject>granulozitatea frezelor</dc:subject> <dc:subject>compozit</dc:subject> <dc:subject>ţesuturi dentare dure</dc:subject> <dc:title>Взаимосвязь между зернистостью алмазных боров и плотностью прилегания композита к твёрдым тканям зубов</dc:title> <dc:type>info:eu-repo/semantics/article</dc:type> </oai_dc:dc>
