[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.

A comparison of nimesulide beta cyclodextrin and nimesulide in postoperative dental pain.

The aim of this study was to assess the efficacy and tolerability of single doses of nimesulide beta cyclodextrin compared with nimesulide in patients with dental pain following surgical procedures. This was a randomised, double-blind, between-patient, multicentre study involving 148 outpatients suffering from moderate to severe pain, who received single doses of either 400 mg nimesulide beta cyclodextrin or 100 mg nimesulide. The principal criterion for efficacy was pain intensity assessed on a visual analogue scale (VAS) 15 minutes after drug intake. Pain intensity was further evaluated 30, 45, 90, 120, 180, 240 and 360 minutes after dosing. Pain relief was evaluated at the same time points by means of a categorical scale. The time point of first pain relief, the use of rescue medication and the global evaluation of efficacy were also recorded. The reduction in pain intensity was significantly more pronounced in the nimesulide beta cyclodextrin group at 15, 30, 45 and 60 minutes (p < 0.01). Pain relief was significantly greater (p < 0.05) and more rapid with nimesulide beta cyclodextrin. In the patient overall assessment of efficacy, nimesulide beta cyclodextrin and nimesulide were rated excellent or good by 95% and 92% respectively; only one patient in the nimesulide beta cyclodextrin group needed rescue medication. Both study drugs were effective and well tolerated in the treatment of acute dental pain, with nimesulide beta cyclodextrin showing a faster onset of analgesic action.
