Study summary

Objective: To evaluate the impact of mouthguards (MG) on acceptability, incidence of soft tissue injuries, periodontal and salivary parameters, as well as on the perception of the body in sports practice (PeCoPes) and on the quality of life of athletes, and evaluate the consequences of use on the characteristics, state of conservation, and biological and physical properties of the MG itself. Methodology: This is a longitudinal study that will include children, adolescents, and adults aged 7 to 30 years who practice sports and require MGs. Sociodemographic data, medical history, dental history, dietary habits, and sports practice data will be collected. Participants will undergo a complete oral clinical examination. Data on knowledge of traumatic dental injuries (TDI) and MGs will also be collected. Before the MG is delivered, immediately after installation, and at 1, 3, and 6 months after use, the following parameters will be evaluated: presence of mucosal injuries, visible plaque index, gingival bleeding index, salivary flow, salivary pH, buffering capacity, and salivary microorganism count. Acceptability will be evaluated before the MG is delivered, immediately after delivery, and at 1, 3, and 6 months after use. PeCoPes and quality of life will be assessed before, 1, 3, and 6 months after MG use. The MG will be evaluated for bacterial contamination, delamination, roughness, dimensional changes related to shape and thickness, color change, and conservation status. The data will be tabulated and analyzed using SPSS 21.0, and appropriate statistical tests (p\<0.05) will be performed according to the study objectives.

Study arms

  • Experimental
    Sport Mouthguard

    After the initial consultation for clinical examination data collection and anamnesis, an impression of the patient's upper dental arch will be made to create a custom mouthguard. This mouthguard will be made using two 3mm vinyl acetate ethylene sheets, following the recommendations for an appropriate mouthguard regarding trauma prevention and patient comfort.

    Device: Sport custom mouthguard

Interventions

  • DeviceSport custom mouthguard

    This mouthguard will be made using two 3mm vinyl acetate ethylene sheets in a vacuum machine, following the recommendations for an appropriate mouthguard regarding trauma prevention and patient comfort. The patients will be monitored after 1, 3, and 6 months of using the mouthguard.

What researchers measure

Primary outcomes

  1. Acceptability

    Acceptability will be assessed through a questionnaire on changes in the oral cavity associated with the use of the MG or in the MG itself. This questionnaire was developed by the authors of the study.

    Time frame: Acceptability will be evaluated before the MG is delivered, immediately after delivery, and at 1, 3, and 6 months after use.

  2. Incidence of soft tissue injuries

    The following parameter will be evaluated: presence of mucosal injuries through clinical examinations

    Time frame: Before the MG is delivered, and at 1, 3, and 6 months after use

  3. Periodontal and salivary parameters

    The following parameters will be evaluated: visible plaque index, gingival bleeding index, salivary flow, salivary pH, buffering capacity, and salivary microorganism count.

    Time frame: Before the MG is delivered, immediately after installation, and at 1, 3, and 6 months after use.

Secondary outcomes

  1. The perception of the body in sports practice (PeCoPes)

    The perception of the body in sports practice (PeCoPes) will be assessed through a previously validated questionnaire.

    Time frame: PeCoPes will be assessed before, 1, 3, and 6 months after MG use.

  2. The quality of life of athletes

    The quality of life will be assessed through some previously validated questionnaires.

    Time frame: Quality of life will be assessed before, 1, 3, and 6 months after MG use.

  3. The consequences of use on the characteristics, state of conservation, and biological and physical properties of the MG itself.

    The MG will be evaluated for bacterial contamination, delamination, roughness, dimensional changes related to shape and thickness, color change, and conservation status.

    Time frame: Before the MG is delivered, immediately after installation, and at 1, 3, and 6 months after use.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Jun 2024 (actual). Primary completion is estimated for Aug 2025, 14 months after the start.

Of 741 non-industry interventional studies with no phase under Behavior, half reached primary completion within 14 months of starting (the median), counting those still running; a quarter within 5 and three quarters within 32. This study's planned 14 months is close to that.

Counting every sponsor, half of 757 studies reached it within 13 months; a quarter within 5 and three quarters within 32.

How these figures are worked out, and which studies are left out of them.

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 Apr 4, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
