Acceptance and Preference of Lidocaine Gel Compared to Injection Anesthesia After Non Surgical Periodontal Treatment

- NCT03354312
- Lead Sponsor
- Chemische Fabrik Kreussler & CO GmbH
- Brief Summary
This project is a national, open label, multicenter, randomized split-mouth study in patients from 18 to 70 years of age to compare the efficacy and acceptability of lidocaine gel compared to injection anesthesia with articaine (infiltration anesthesia for the upper jaw and infiltration or nerve block anesthesia for the lower jaw). It is planned that about 90 patients with a proven moderate periodontitis will be enrolled in 5 German study centers.
Dynexan Mundgel® (lidocaine hydrochloride) is a topical anesthetic gel containing lidocaine that is commercially available as an anesthetic for temporary, symptomatic treatment of pain at the oral mucosa, gingiva and lips. The gold standard for scaling and root planing (SRP) is still the use of injection anesthesia. This raises the question what kind of anesthesia patients would prefer if they had a free choice.
For this study Ultracaine® D-S 1:200,000 (articaine hydrochloride/epinephrine hydrochloride) was selected as the injectable comparator drug because it is the most frequently used anesthetic drug for infiltration and nerve-block anesthesia in Germany at present.

- Primary Outcome Measures
Name Time Method Acceptance and preference of topical lidocaine mouth gel anesthesia 1 hour post-dose of second treatment To compare acceptance and preference of topical lidocaine mouth gel anesthesia vs. injection anesthesia with articaine in patients undergoing subgingival debridement by comparing the proportion of patients after the second periodontal treatment who prefer topical anesthesia with lidocaine gel against the injection anesthesia with articaine to a proportion of 0.5; the patient rates the preferred anesthesia method on a questionnaire by stating if the patient's preference is treatment with anesthetic gel, treatment with anesthetic injection, or no preference
- Secondary Outcome Measures
Name Time Method Duration of anesthetic effect 1 hour post-dose Compare the duration of anesthetic effect in both treatment groups; the treating physician rates the duration of the anesthetic effect on a questionnaire by using German school grades (1 = very good, 2 = good, 3 = satisfactory, 4 = adequate, 5 = inadequate, 6 = insufficient) after each treatment visit.
Patient compliance 1 hour post-dose Compare the patient compliance in both treatment groups; the treating physician rates the patient compliance on a questionnaire by using German school grades (1 = very good, 2 = good, 3 = satisfactory, 4 = adequate, 5 = inadequate, 6 = insufficient) after each treatment visit.
Treating physicians preference 1 hour post-dose of second treatment Evaluation which of the anesthetic methods the treating physician prefers. The treating physician rates the preferred anesthesia method on a questionnaire by stating if the treating physician's preference is treatment with anesthetic gel, treatment with anesthetic injection, or no preference
Re-Evaluation of patients preference 25 hours post-dose of second treatment Re-evaluation of preference of topical lidocaine mouth gel anesthesia vs. injection anesthesia with articaine 24 h after end of last treatment. The patient again rates the preferred anesthesia method by stating if his/her preference is treatment with anesthetic gel, treatment with anesthetic injection, or no preference. The preference 24 h after end of last treatment is collected by using the patient diary.
Assessment of pain 1 hour post-dose Comparative assessment of pain the patients experienced during treatment; a visual analogue scale (100mm, 0 = no pain, 100 = maximum pain) will be used for maximum pain and average pain Rating after each treatment visit
Side Effects 1, 5, 25 hours post-dose Evaluate type and number of side effects (incl. after-effects due to study Treatment up to 24h after each treatment visit by use of a patient diary)
Overall patient satisfaction with anesthesia 1 hour post-dose Evaluation of the overall patient satisfaction with anesthesia. The patient rates the overall satisfaction on a questionnaire by using German school grades (1 = very good, 2 = good, 3 = satisfactory, 4 = adequate, 5 = inadequate, 6 = insufficient) after each treatment visit.
Willingness to pay 1 hour post-dose of second treatment Evaluation of the willingness to pay for lidocaine gel by using a questionnaire (willingness to pay 0, 1-5, 5-10, 10-15, 15-20 or \>20 €)
Handling/Application 1 hour post-dose Compare the handling/application of both methods; the treating physician rates the handling/application on a questionnaire by using German school grades (1 = very good, 2 = good, 3 = satisfactory, 4 = adequate, 5 = inadequate, 6 = insufficient) after each treatment visit.
Onset of anesthetic effect 1 hour post-dose Compare the onset of anesthetic effect in both treatment groups; the treating physician rates the onset of the anesthetic effect on a questionnaire by using German school grades (1 = very good, 2 = good, 3 = satisfactory, 4 = adequate, 5 = inadequate, 6 = insufficient) after each treatment visit.
Anesthesia re-application/rescue anesthesia 1 hour post-dose Assess the number of re-application of the anesthetic gel or the rescue anesthesia injections that are required in every treatment group
