About this study

Official title: The Effects of Pranayamic Breathing Techniques and Tongue Exercises on Oral Microbiota in Children Aged 7-12 Years

This study aims to evaluate the effects of pranayamic breathing techniques and tongue exercises on oral microbiota in children aged 7-12 years. Children will be grouped according to their breathing patterns (mouth or nasal breathing), and a structured breathing and tongue exercise program will be applied. Saliva samples will be collected before and after the intervention to analyze changes in oral microbiota. The study will include approximately 80 participants and is expected to last for 6 months. There are no anticipated risks for participants. The findings of this study may contribute to a better understanding of the relationship between breathing patterns, oral exercises, and oral health in children.

Read the detailed description

This study is designed to investigate the effects of pranayamic breathing techniques, tongue exercises, and tongue cleaning on oral microbiota in children aged 7-12 years. Participants will be classified based on their breathing patterns as mouth breathers or nasal breathers. Each group will undergo a structured intervention program that includes specific breathing techniques, tongue exercises, and, in selected subgroups, tongue cleaning over a defined period.

Saliva samples will be collected from all participants before and after the intervention. These samples will be analyzed using microbiological methods to evaluate changes in oral microbiota composition. The study aims to compare the microbiological outcomes between different breathing patterns and to assess the potential benefits of the applied interventions.

Informed consent will be obtained from all participants and their legal guardians prior to participation. All collected samples and data will be anonymized to ensure participant confidentiality.

This research is expected to provide insights into the relationship between breathing habits, oral functions, tongue hygiene practices, and oral microbial balance in children. The findings may contribute to preventive and therapeutic approaches in pediatric dentistry, particularly in managing the effects of mouth breathing on oral health.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Pranayamic Breathing and Tongue ExercisesBehavioural

    Participants will perform a structured program including pranayamic breathing techniques and tongue exercises, and, in selected subgroups, tongue cleaning. The program will be applied regularly over the study period, and saliva samples will be collected before and after the intervention to assess changes in oral microbiota.

Study groupRoleWhat they receive
Mouth Breathing GroupExperimentalParticipants with mouth breathing habits will be included in this group. A structured program consisting of pranayamic breathing techniques, tongue exercises, and, in selected subgroups, tongue cleaning will be applied. Saliva samples will be collected before and after the intervention to evaluate changes in oral microbiota.
Receives: Behavioral: Pranayamic Breathing and Tongue Exercises
Nasal Breathing GroupExperimentalParticipants with nasal breathing habits will be included in this group. A structured program consisting of pranayamic breathing techniques, tongue exercises, and, in selected subgroups, tongue cleaning will be applied. Saliva samples will be collected before and after the intervention to evaluate changes in oral microbiota.
Receives: Behavioral: Pranayamic Breathing and Tongue Exercises

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in oral microbiota alpha diversity as measured by the Shannon diversity index from 16S rRNA gene sequencing of saliva samples

    This outcome evaluates the effect of the intervention (pranayamic breathing exercises, tongue exercises, and tongue-cleaning practice) on the diversity of the oral microbiota. Alpha diversity will be assessed from saliva samples using 16S rRNA gene sequencing and quantified using the Shannon diversity index. The mean Shannon index at baseline will be compared with the value after the 8-week intervention, and the change from baseline will be reported.

    Measured: 8 weeks

Secondary outcomes (1)
  1. Salivary Nitric Oxide Levels

    Salivary nitric oxide levels will be measured using test strips before and after the intervention.

    Measured: 8 weeks

Questions about this trial

What is this clinical trial studying?

A study testing Pranayamic Breathing and Tongue Exercises in people with Mouth Breathing and Oral Microbiota, run by Gulcin Ozsen at 1 site in Turkey (Türkiye).

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 10 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Gulcin Ozsen, DDS (+90 555 711 99 39, gulcinozsen@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in oral microbiota alpha diversity as measured by the Shannon diversity index from 16S rRNA gene sequencing of saliva samples (time frame: 8 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Aug 2026.
