Study 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.

Terms in these criteria, in plain language(7)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Excipients

The other ingredients in a medicine besides the active drug, such as fillers, colours or preservatives.

What researchers measure

Primary outcomes

  1. Acceptance and preference of topical lidocaine mouth gel anesthesia

    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

    Time frame: 1 hour post-dose of second treatment

Secondary outcomes

  1. Assessment of pain

    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

    Time frame: 1 hour post-dose

  2. Side Effects

    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)

    Time frame: 1, 5, 25 hours post-dose

  3. Handling/Application

    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.

    Time frame: 1 hour post-dose

  4. Onset of anesthetic effect

    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.

    Time frame: 1 hour post-dose

  5. Duration of anesthetic effect

    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.

    Time frame: 1 hour post-dose

  6. Patient compliance

    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.

    Time frame: 1 hour post-dose

  7. Treating physicians preference

    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

    Time frame: 1 hour post-dose of second treatment

  8. Anesthesia re-application/rescue anesthesia

    Assess the number of re-application of the anesthetic gel or the rescue anesthesia injections that are required in every treatment group

    Time frame: 1 hour post-dose

  9. Overall patient satisfaction with anesthesia

    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.

    Time frame: 1 hour post-dose

  10. Willingness to pay

    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 €)

    Time frame: 1 hour post-dose of second treatment

  11. Re-Evaluation of patients preference

    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.

    Time frame: 25 hours post-dose of second treatment
