[Materials for mouth protectors].

Taking into account the number of teeth which are yearly irreversible traumatised during sport activities, the general use of mouthguards would contribute positively to the prevention of dental injuries. Custom-made mouthguards are more comfortable to wear and offer better retention and protection than stock and mouth-formed mouthguards. Different kinds of materials are available on the market for the construction of mouthguards. A polyethylene-polyvinylacetate copolymer (EVA) is the most suitable material. EVA allows the inclusion of hard or soft layers within the mouthguard. The thickness of a mouthguard is important for the reduction of applied forces to teeth: energy absorption capacity increases with material thickness. Increased thickness however, is associated with a reduction of comfort. Therefore, it is important that dentists take the patients' wishes and demands on both comfort and protection into consideration. A description of the clinical and technical method for the construction of a custom made mouthguard is given.

[Frequency and nature of anterior tooth injuries and the use of mouth protectors in sports clubs in Bern].

Tooth injuries are frequently associated with sports injuries. Most of them could be minimized or prevented by the use of a mouthguard. The present study investigated the occurrence of tooth injuries and the attitude of athletes of Bernese sports clubs towards mouthguards, by means of a questionnaire and clinical examination. A total of 172 out of 200 athletes from six sports clubs, who were contacted directly at the sports fields, returned the questionnaire. Fifty of them owned a mouthguard (= 29.1%) and 54 reported having suffered dental trauma. The majority of athletes did not wear a mouthguard, despite acknowledging its usefulness. Even after a dental injury, the rate of mouthguard-acceptance increased just marginally; only 38.9% of all injured athletes were wearing a mouthguard after dental trauma. Most of the athletes had not considered wearing a mouthguard at all. For many of them, impairment of speech and breathing and discomfort were reasons not to wear a mouthguard. Of the 54 reported athletes with dental trauma, 48 were examined clinically. The upper central incisors were by far the most frequently injured teeth. The clinical examination used an injury severity index (NIDR-Index, National Institute of Dental Research) ranging from grade 0 (no visible damage), to grade 6 (loss of tooth). The most common finding was grade 4 (injuries that were treated by reconstruction). In conclusion there is a need to optimize information for athletes concerning mouthguards and sports injuries. Providing such information is not only the responsibility of coaches and trainers, but also of dentists.
