Study summary

Objective: To investigate, through a controlled and randomized clinical trial, the effectiveness of using Melissa officinalis in different concentrations in the treatment of children and adolescents with probable sleep bruxism. Methodology: This is a randomized, triple-blind, crossover, and placebo-controlled clinical trial. The research participants will be children aged 5 to 10 years old and adolescents aged 11 to 16 years old who attend dental treatment at the FO/UFRJ Pediatric Dentistry Clinics. After approval by the Human Research Ethics Committee, children and adolescents will undergo homeopathic treatment with Melissa officinalis in different concentrations for possible sleep bruxism. In addition, research participants will undergo an assessment of TMJ, sleep, circadian cycle, quality of life, and quality of life related to oral health. The data will be tabulated and analyzed according to sex, age group, presence of possible sleep bruxism, presence or absence of TMD, circadian characteristics, presence or absence of sleep disorders, daytime and nighttime behavioral characteristics. The data will be tabulated and evaluated using SPSS 21.0. Absolute and relative frequency, odds ratio, correlation analysis and other relevant analyzes and statistical tests (p\<0.05) will be carried out in accordance with the objectives proposed by the study

Study arms

  • Placebo comparator
    Placebo

    It will be administered for a period of 30 days, once a day before bed, with a 15-day wash-out interval. The placebo, a drug without active substance, that will be administered to research participants will be the biotherapeutic vehicle, that is, 30% alcohol (v/v), which is commonly used as a vehicle for homeopathic medicines.

    Drug: Placebo

  • Experimental
    Melissa officinalis 6 CH

    It will be administered for a period of 30 days, once a day before bed, with a 15-day wash-out interval. This concentration that will be administered to research participants will be the biotherapeutic vehicle, that is, 30% alcohol (v/v), which is commonly used as a vehicle for homeopathic medicines.

    Drug: Melissa

  • Experimental
    Melissa officinalis 9 CH

    It will be administered for a period of 30 days, once a day before bed, with a 15-day wash-out interval. This concentration that will be administered to research participants will be the biotherapeutic vehicle, that is, 30% alcohol (v/v), which is commonly used as a vehicle for homeopathic medicines.

    Drug: Melissa

  • Experimental
    Melissa officinalis 12 CH

    It will be administered for a period of 30 days, once a day before bed, with a 15-day wash-out interval.

Interventions

  • DrugMelissa

    The test solutions will be administered once a day through administration in drops for children between 5 and 10 years old and for adolescents between 11 and 16 years old. As participants will be between 5 and 16 years old, children will be given a minimum of 5 and a maximum of 10 drops of the solutions per individual (Tavares-Silva, Holandino et al. 2019) as well as a maximum of 10 drops for adolescents of solutions per individual (Taylor, Lancaster et al. 2000). Highlighting that the prescription of Melissa officinalis will be at night, around 20/30 minutes before bedtime, respecting the indications for the medications described in the Hahnemannian Materia Medica (Vijnovsky, 2003). All medications must be taken away from meals and they will be instructed not to use mentholated substances, respecting a minimum time of 30 minutes.

  • DrugPlacebo

    It will be administered for a period of 30 days, once a day before bed, with a 15-day wash-out interval. The placebo, a drug without active substance, that will be administered to research participants will be the biotherapeutic vehicle, that is, 30% alcohol (v/v), which is commonly used as a vehicle for homeopathic medicines.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jan 19, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
