[Pain management after third molar extraction. Observations of the use of mefenamic acid and rofecoxib in the treatment of postoperative pain in the dental office].

Pain monitoring is often inadequate in the ambulant field to assure therapy results. Today NSAID take the centre in acute pain and inflammation control in dental interventions. Compared to conventional non-selective NSAID modern selective Cyclooxygenase-2 inhibitors (COX-2) provide the potential for improved compatibility and simplified medication with heightened effectiveness in acute postoperative toothaches. The aim of this study was to compare the effect of selective COX-2 inhibitors with NSAID after operative wisdom tooth extraction in 30 ambulant patients. The pain curve under mefenamine acid showed a significant increase during the first 48 hours after extraction. With rofecoxib a continuous pain decrease with the lowest stand 48 hours after intervention was registered. One week after extraction the patient's satisfaction was in favour of rofecoxib, which showed a clearly prolonged analgetic effect over 24 hours. Additionally rofecoxib as a COX-2 selective inhibitor doesn't bear the risk for severe non-anticipatable gastrointestinal side effects or prolonged bleeding after surgical intervention.

Ciliated epithelium-lined radicular cysts.

OBJECTIVE: This report describes 3 cases of ciliated epithelium-lined radicular cysts among 256 apical periodontitis lesions and also illustrates the occurrence of an Actinomyces-infected periapical cyst. STUDY DESIGN: Serial and step serial sections of 256 plastic-embedded root apices with attached apical periodontitis lesions that were prepared for a previous investigation were reviewed for the presence of ciliated epithelium-lined radicular cysts. The lesions that were found to have such epithelial lining were examined in a transmission electron microscope to elaborate the fine structure of the ciliated cells. RESULTS: A total of 3 ciliated columnar epithelium-lined cysts was found among the 256 apical periodontitis lesions examined. Two of the lesions also contained stratified squamous epithelium. All 3 lesions affected maxillary premolars. One of the lesions was a true cyst, and the other 2 were periapical pocket cysts. The lumen of 1 of the latter revealed the presence of typical "ray-fungus" actinomycotic colonies. CONCLUSION: Although the stratified squamous component of the epithelia that lined the radicular cysts reported here may be derived from the cell rests of Malassez, the ciliated epithelial cells may be of sinus origin. Microbial agents from diseased root canals can advance into radicular cysts, particularly in pocket cysts, with the possible threat of such infection in upper posterior teeth spreading into the maxillary sinus.
