Minimally invasive approach supported by the use of mouthguard in the treatment of sport-related root fracture: a case report.

All sporting activities have an associated risk of orofacial injuries that can affect the oral health-related quality of life (OHRQoL). A custom-made mouthguard can be used as an adjuvant treatment for faster recovery of an athlete to resume sporting activities. This case report described a minimally invasive approach by use of mouthguard for treating sport-related root fracture and its impact on OHRQoL. In a dental trauma care program, the patient was treated by repositioning the coronary portion and the confection of a splint. It was opted to not realize the endodontic treatment and the patient was inserted in a rigorous clinical and radiographic follow-up. A custom-made mouthguard was made, which allowed for the immediate return of athletes to practicing sports. The athlete's OHRQoL was negatively impacted by dental trauma, but the treatment proposed was associated with the use of custom-made mouthguards. After 2 years, the absence of radiographical lesions and a positive response to sensibility tests were observed. The success of the minimally invasive approach was attributed to immediate conduct following dental trauma, the implementation of follow-up, and associated with the use of custom-made mouthguard.
