[CO2 laser sterilization in periradicular surgery: a clinical follow-up study].
Periradicular surgery combined with final laser sterilisation was performed on 62 teeth of 50 patients by 3 trained oral surgeons, according to a well defined treatment protocol. It concerned a 5 Watt continuous wave CO2-laser. After a follow-up period ranging from 6 to 17 months all patients were recalled. 28 patients (56%) or 33 teeth (53%) could be evaluated. The successrate was determined by a questionnaire, a standard clinical examination and an X-ray evaluation. Complete surgical healing was found in 59% of the teeth and incomplete healing in 23%. Uncertain healing and unsatisfactory healing were observed in respectively 11% and 7% of the teeth. Better healing results were found in elements with one endodontic canal (67% complete healing) and when endododontic treatment was combined with the intervention (71% complete healing). Comparison of the results of the present study with comparable studies without laser sterilisation, showed however no statistical significant improvement.
