Effect of Occlusal Accommodation of the Mouthguard on the Degree of Satisfaction of Water Polo Players: A Randomized Crossover Study

This study assesses the effect of adjusting the occlusal surface of a custom-made mouthguard on the degree of satisfaction with a mouthguard among water polo players. Twenty-four water polo players will wear a custom-made conventional mouthguard and a custom-made mouthguard with occlusal adjustment, two weeks per mouthguard. They will wear it during training sessions and for competing. The sequence will be randomized to obtain one-half of the participants starting the first week wearing the conventional mouthguard, and the other half wearing the mouthguard with occlusal adjustment. The participants will rate the degree of interference with oral functions or discomfort in reference to speech, breathing, swallowing, gag reflex, fits too tight, fits too loose, aesthetics and athletic performance, in a 10-point scale, considering 0 no discomfort/interference and 10 maximum discomfort/interference. After each session, players also rated the perception of protection, the degree of improvement on athletic performance and the degree of satisfaction in a 10-point scale, considering 0 no protection/satisfaction and 10 maximum protection/satisfaction.

Study Overview

Detailed Description

This crossover intervention study aims to assess the effect of adjusting the occlusal surface of a custom-made mouthguard on the degree of satisfaction with a mouthguard among water polo players. Twenty-four water polo players will participate in this randomized crossover trial. Two different custom-made mouth guards will be made for each participant, a conventional one and an occlusal-adjusted mouthguard. Both types of mouthguard will be fabricated using a pressure molding device and 4-mm ethyl vinyl acetate foils. The conventional mouth guards will be made at 2 mm from the full depth of the labial sulcus, covering the second maxillary molar, and with the palatal margin extending 2 mm from the cervical line. To fabricate the occlusal adjusted mouthguard a second 2-mm foil of ethyl vinyl acetate will be formed over the initial 4-mm layer. The maxillary and mandibular casts mounted to an articulator using an inter occlusal record will facilitate the accommodation of the occlusal surface to the antagonistic teeth. The participants will be instructed to wear the mouth guards during training sessions and competitions. The sequence of use will be randomized to obtain one half of the participants beginning the first and the fourth week wearing the conventional mouthguard and the second and the third wearing the occlusal-adjusted mouthguard. The other half will start wearing the first and the fourth week the mouthguard with occlusal-adjusted mouthguard and the second and third week wearing the conventional mouthguard. The participants will evaluate on a 10-point scale for discomfort (gag reflex, fits too tight, fits too loose), interference with functions (speech, breathing, swallowing, aesthetics, and athletic performance), protection, and general satisfaction after each training session or match.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Degree of satisfaction using a questionnaire
Time Frame: Weeks 1-4
Participant satisfaction will be assessed by asking the question "How satisfied are you with your mouthguard?" using a 0-10 point scale, considering 0= totally dissatisfied and 10 = totally satisfied. Players rated the mouthguard just after each training session or after each match.
Weeks 1-4

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Degree of interference on speech using a questionnaire
Time Frame: Weeks 1-4
The degree of interference on speech while using the mouthguard will be assessed by asking the question "How much do you think wearing the mouthguard interferes your ability to speech?" using a 0-10 point scale (considering 0= anything to 10= very much). Players rated the mouthguard just after each training session or after each match.
Weeks 1-4
Degree of interference on breathing using a questionnaire
Time Frame: Weeks 1-4
The degree of interference on breathing while using the mouthguard was assessed by asking the question "How much do you think wearing the mouthguard interferes your ability to breath?" using a 0-10 point scale (considering 0= anything to 10= very much). Players rated the mouthguard just after each training session or after each match.
Weeks 1-4
Degree of interference on swallowing using a questionnaire
Time Frame: Weeks 1-4
The degree of interference on swallowing while using the mouthguard will be assessed by asking the question "How much do you think wearing the mouthguard interferes your ability to swallow?" using a 0-10 point scale (considering 0= anything to 10= very much). Players rated the mouthguard just after each training session or after each match.
Weeks 1-4
Degree of discomfort regarding the gag reflex using a questionnaire
Time Frame: Weeks 1-4
