title: Clinical effects of an essential oil solution used as a coolant during ultrasonic root debridement.
abstract: OBJECTIVE
  The use of chlorhexidine and povidone iodine solutions applied as a coolant during ultrasonic root debridement for the treatment of chronic periodontitis has been described. Hitherto, this application has not yet been extensively investigated for essential oil solutions. The goal was to clinically explore this and to compare to water irrigation.
  
  
  METHODS
  Thirty-five chronic periodontitis patients participated in a single-blind randomized controlled clinical study. Patients were randomly allocated to the control group (n=18) or test group (n=17) receiving oral hygiene instructions and ultrasonic root debridement using water as a coolant, respectively, a pure essential oil solution. Oral hygiene was reinforced if necessary at each occasion, and clinical parameters were collected at baseline and after 1 and 3 months.
  
  
  RESULTS
  Significant pocket reduction (control, 1.02 mm; test, 0.89 mm) and clinical attachment gain (control and test, 0.48 mm) were shown in both groups. However, there were no significant differences between the groups at any point in time for any of the parameters.
  
  
  CONCLUSIONS
  Essential oil solutions do not offer a clinical benefit over water when used as a coolant during ultrasonic root debridement for the treatment of chronic periodontitis.
