Abstract:

Objective To compare periodontal ligament anesthesia using a computer-controlled local anesthetic delivery system(C-CLADS)and submucosal infiltration anesthesia using a manually operated syringe in terms of the injection pain,anesthetic effect,anesthetic dose,and complications in healthy volunteers. Methods Fifty healthy volunteers,aged 18 to 56 years,were recruited from September 2012 to May 2013 in the Department of Stomatology of Peking Union Medical College Hospital. A randomized self-controlled trial was conducted by applying a periodontal ligament anesthesia on one side and conventional manual submucosal infiltration anesthesia to the other(control)side. The differences in the onset time of anesthesia,drug dosage,anesthetic effect,and the degree of injection pain were compared. The complications associated with the two anesthesia methods were also recorded. Results When using C-CLADS to perform a periodontal ligament anesthesia,the drug dosage and the severity of injection pain were significantly less than those of conventional manual infiltration anesthesia[drug dosage:(0.34±0.09)ml vs.(0.55±0.13)ml,P<0.01;VRS:0.42±0.73 vs. 1.38±0.92,P<0.01;VAS:1.34±1.21 vs. 3.10±1.70,P<0.01]. The anesthesia success rate was approximately 90.0%,showing no significant difference relative to conventional submucosal infiltration anesthesia. Approximately 24% of the volunteers experienced postoperative pain after periodontal ligament anesthesia. Conclusion Compared with conventional submucosal infiltration anesthesia using manual syringes,periodontal ligament anesthesia performed using C-CLADS can reduce the injection pain and drug dosage while achieving a satisfactory anesthetic effect;however,a considerable proportion of cases may experience postoperative pain.
