- Brief Summary
This study assesses the effect of incorporating a hard labial layer to the front zone of a custom-made mouthguard on the degree of satisfaction of rugby players. Twenty-four rugby players will wear a custom-made Bioplast Xtreme conventional mouthguard (Bioplast Xtreme 4 × 125 + Bioplast 2 x 125; Scheu-Dental Company) and a custom-made Bioplast Xtreme Pro mouthguard (Bioplast Xtreme 4mm × 125 + Duran Layer 0.75mm; Bioplast 2mm x 125), two weeks per mouthguard. They will wear it during training sessions and competitions. The sequence will be randomized for one-half of the participants to start wearing the Bioplast Xtreme conventional and the other half the Bioplast Xtreme Pro mouthguard the first week.
The participants will rate the degree of interference with oral functions or discomfort in reference to speeking, breathing, swallowing, gag reflex, tight or loose fitting, aesthetics and athletic performance, in a 10-point scale, considering 0 no discomfort/interference and 10 maximum discomfort/interference. After each session, players will also rate the perception of the 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.
- Detailed Description
This crossover intervention study aims to assess the effect of incorporating a hard labial layer to the front zone of a custom-made mouthguard on the degree of satisfaction of rugby players. Twenty-four rugby players will participate in this randomized crossover trial. Three hydrocolloid impressions will be made, two of their maxillary arches and one of their mandibular arches, and the casts will be poured immediately with Type IV dental stone. An interocclusal record will be obtained using an extra hard wax covering the tip of two wooden tongue depressors to assure a near centric relation and a minimum interocclusal distance of approximately 2 mm. Two different custom-made mouth guards will be made for each participant, a Bioplast Xtreme conventional mouthguard (Bioplast Xtreme 4 × 125 + Bioplast 2 x 125; Scheu-Dental Company) and a custom-made Bioplast Xtreme Pro mouthguard (Bioplast Xtreme 4mm × 125 + Duran Layer 0.75mm; Bioplast 2mm x 125). Conventional mouthguard will be fabricated using a pressure molding device and a 4-mm ethyl vinyl acetate foil 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 adjustment 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 the inter occlusal record will facilitate the accommodation of the occlusal surface to the antagonistic teeth. Bioplast Xtreme Pro will be made by the same procedure, except the incorporation of an extra layer of Duran between 4mm ethyl vinyl acetate foil and 2 mm ethyl vinyl acetate foil. 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 wearing Xtreme Conventional mouthguard the first and the fourth week and the Xtreme Pro mouthguard the second and the third week. The other half will start wearing the first and the fourth week the Xtreme Pro mouthguard and the second and third week the Xtreme conventional mouthguard. The participants will evaluate using a 10-point scale the discomfort (gag reflex, tight or loose fitting), the level of interference with functions (speeking, breathing, swallowing, aesthetics and athletic performance), the protection, and the general satisfaction after each training session or match.

- Primary Outcome Measures
Name Time Method Degree of satisfaction using a questionnaire 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.
- Secondary Outcome Measures
Name Time Method Degree of discomfort regarding the gag reflex using a questionnaire Weeks 1-4 The degree of discomfort regarding the gag reflex while using the mouthguard will be assessed by asking the question "How much do you think wearing the mouthguard causes a gag reflex?" 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.
Cost-effectiveness analysis by assessing the degree of satisfaction and the cost of the mouthguard Weeks 1-4 The time spent in the laboratory setting and the cost of the materials will be considered for the estimation of the cost-effectiveness of the mouthguard. Effectiveness will be considered as the degree of satisfaction with the mouthguard perceived by the participant.
Degree of interference on speech using a questionnaire 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.
Degree of interference on breathing using a questionnaire 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.
Degree of interference on swallowing using a questionnaire 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.
Degree of discomfort because the mouthguard fits too tight using a questionnaire Weeks 1-4 The degree of discomfort because the mouthguard fits too tight will be assessed by asking the question "How much do you think the mouthguard fits too tight?" 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.
Degree of discomfort related to the dislodgement of the mouthguard using a questionnaire Weeks 1-4 The degree of discomfort because the mouthguard dislodges will be assessed by asking the question "How much do you think the mouthguard fits too loose?" 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.
Degree of interference on aesthetics using a questionnaire Weeks 1-4 The degree of interference on aesthetics while using the mouthguard will be assessed by asking the question "How much do you think wearing the mouthguard interferes on aesthetics?" 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.
Degree of interference on athletic performance using a questionnaire Weeks 1-4 The degree of interference on athletic performance while using the mouthguard will be assessed by asking the question "How much do you think wearing the mouthguard interferes athletic performance?" using a 0-10 point scale (considering 0= anything to 10= very much).
