[Finishing and polishing of an anterior hybrid composite--Herculite XR. SEM evaluation].

A study was a conducted in order to discover finishing and polishing effectiveness, by particular operative method, on HERCULITE XR, sub-micron hybrid composite. The study was realized on 35 incisors extracted for periodontal reasons, treated with "labial veneers" according to Jordan (1987), divided into 7 groups each containing 5, and finished with different technique. After treatment, the teeth were subjected to SEM examination. The results showed that the high speed finishing technique by twelve and thirty fluted carbide burs and final polishing with Command Ultrafine Luster Paste produces the smoothest and flatest surface of HERCULITE XR. Furthermore the HERCULITE XR/enamel margin doesn't appear fractured or disrupted. Since finishing and polishing rotary techniques in accordance with the characteristic of each type of composite resins.
