title: Evaluation of patient perceptions after frenectomy operations: a comparison of carbon dioxide laser and scalpel techniques.
abstract: BACKGROUND
  A frenum that encroaches on the margin of the gingiva may interfere with plaque removal and cause tension. Frenectomy is the complete removal of the frenum that can be made by scalpels or with soft tissue lasers. The aim of this article was to compare the degree of postoperative pain, such as discomfort and functional complications (eating and speech), experienced by patients after two frenectomy operation techniques.
  
  
  METHODS
  Forty patients requiring frenectomy were randomly assigned to have treatment either with a conventional technique or with a carbon dioxide (CO2) laser. The postoperative pain and functional complication ratings of each patient were recorded using a visual analog scale on days 1 and 7.
  
  
  RESULTS
  The results indicated patients treated with the CO2 laser had less postoperative pain and fewer functional complications (speaking and chewing) (P <0.0001 each) and required fewer analgesics (P <0.001) compared to patients treated with the conventional technique.
  
  
  CONCLUSIONS
  This clinical study indicates that CO2 laser treatment used for frenectomy operations provides better patient perception in terms of postoperative pain and function than that obtained by the scalpel technique. Considering the above advantages, when used correctly, the CO2 laser offers a safe, effective, acceptable, and impressive alternative for frenectomy operations.
