To assess the incidence and awareness of taekwondo athletes in Saudi Arabia regarding oral and maxillofacial (OMF) injuries and their prevention. Methods: In this cross-sectional study, an online questionnaire about the incidence and awareness of OMF injuries and their prevention was developed and distributed to taekwondo athletes in Saudi Arabia via their coaches.  Results: Sixty-eight responses were collected. The mean age of the participants was 29.3±9.1 years and 97% of them were males. Most of the participants (83%) believed that they are vulnerable to OMF injuries during practice...

There appears to be much confusion or misinformation worldwide regarding mouthguards and their use in sports. In an effort to clarify where the international dental community stands on mouthguards and mouthguard research, the workshop looked at some important questions. The goal is to one day formulate consensus statements related to these questions, which will be based on current scientific evidence-based research, to motivate the international community of the importance of dentally fitted laminated mouthguards and the wearing of them by athletes of all sports...

BACKGROUND/AIMS: Fabrication of mouthguards should be performed properly. However, the appropriate heating temperature for fabricating a pressure-formed mouthguard has not been determined. The aim of this study was to examine the influence of the heating temperature on the fabrication of a pressure-formed mouthguard. MATERIALS AND METHODS: Mouthguard sheets of 3.8 mm ethylene vinyl acetate were pressure formed on a working model at three heating temperatures: 80°C, 100°C, and 120°C...

BACKGROUND/AIM: Mouthguard thickness is important for the prevention from orofacial trauma during sports. However, it is difficult to maintain the necessary thickness after forming the mouthguard. The aim of this study was to evaluate a pressure-forming method using a single mouthguard sheet. MATERIALS AND METHODS: A mouthguard sheet of 3.8 mm ethylene vinyl acetate was prepared by cutting 3 mm from the anterior margin of the sheet holder with a length of 7 mm and with the width being from the buccal cusp of the upper right first premolar to the buccal cusp of the upper left first premolar, and compared with the original sheet...

Real-time quantification of head impacts using wearable sensors is an appealing approach to assess concussion risk. Traditionally, sensors were evaluated for accurately measuring peak resultant skull accelerations and velocities. With growing interest in utilizing model-estimated tissue responses for injury prediction, it is important to evaluate sensor accuracy in estimating tissue response as well. Here, we quantify how sensor kinematic measurement errors can propagate into tissue response errors. Using previous instrumented mouthguard validation datasets, we found that skull kinematic measurement errors in both magnitude and direction lead to errors in tissue response magnitude and distribution...

We developed an ethylene vinyl acetate (EVA) containing surface pre-reacted glass-ionomer (S-PRG) filler, as a new mouthguard material for preventing intraoral bacterial infection. We examined its physical properties, antimicrobial activity against a major cariogenic bacterium Streptococcus mutans and a periodontopathogen Porphyromonas gingivalis, and its cytotoxicity toward human gingival epithelial cells. S-PRG filler was added to EVA copolymer at 5, 10, 20, or 40 wt% and was processed into disc-shaped test specimens...

Motocross is a high-risk sport that can cause serious injuries including oral injuries. However, mouthguard use is not mandatory in motocross. This report describes a case of an oral laceration with exposure of bilateral inferior alveolar nerves as a result of a motocross accident in which the patient was not wearing a mouthguard.

INTRODUCTION: Epilepsy is one of the most common neurological disorders. Seizures that occur during attacks may lead to head injuries. It is crucial to establish proper prophylactic management against trauma occurrence, as nowadays prevention is not sufficient. AIM: Assessment of the frequency of head and intraoral trauma during epileptic seizures and to evaluate factors that may predispose to injuries. MATERIAL AND METHODS: The questionnaire was carried out among 106 patients with epilepsy...

Sports mouthguards have the potential to become a microbial reservoir, to produce oral and systemic diseases and cause changes in environmental oral factors, inhibiting the protective effect of saliva. The aim of this study was to monitor, in vivo, oral environmental changes caused by chlorhexidine and sports mouthguards and in vitro, the effects of microbial strains, saliva and chlorhexidine on Ethylene-Vinyl-Acetate (EVA) material. Seventy-two athletes were analyzed at different time points: before training session (T0), post-training (TA), post-training with mouthguard (TB), post-training with mouthguard and chlorhexidine (TC)...

REVIEW
James Ij Green
a mouthguard, also known as a gumshield, mouth protector or sports guard is an appliance that covers the teeth and surrounding mucosa with the aim of preventing or reducing trauma to the teeth, gingival tissue, lips and jaws. The device is usually worn on the maxillary arch and works by separating the maxillary and mandibular dentition, protecting the teeth from the surrounding soft tissue, absorbing or redistributing shock and/or stabilising the mandible during traumatic jaw closure. They may also play a role in preventing and reducing concussion by absorbing impact forces that would otherwise be transmitted through the base of the skull to the brain, although the evidence for this is less conclusive...

PURPOSE: The essential function of mouthguards is protection against the effects of injuries sustained during sports activities. This purpose will be successfully achieved if appropriate materials ensuring sufficient reduction of the injury force are used for mouthguard fabrication. OBJECTIVE: The objective of the study was to investigate the force reduction capability of selected materials as well as to identify which material reduces the impact force to the highest degree...

BACKGROUND/AIMS: Among the diseases related to oral health, such as caries and oral cancer, dental trauma stands out as one of the major public health problems worldwide. The aim of this study was to verify the occurrence of factors associated with traumatic dental injuries (TDIs), including oral health-related quality of life (OHRQoL), sociodemographic characteristics, untreated caries, occlusal problems and contextual variables in 12-year-old Brazilian children. METHODS: This study assessed a complex sample of the National Research in Oral Health (SBBrasil 2010) data on 7240 12-year-old children and contextual features of the municipalities where they lived...

BACKGROUND: Though jaw-repositioning devices have been found to increase size of upper respiratory airways in individuals, the effects of jaw-repositioning mouthguards on respiratory function during exercise have not been fully explored. The purpose of this study is to determine the effects of over-the-counter (OTC) jaw-repositioning mouthguards on respiratory function and aerobic performance in male athletes. METHODS: College-aged, male athletes (N.=20) participated in this randomized, crossover, controlled study...

Participation in sport carries an increased risk of sustaining dental trauma which can be reduced by the use of a mouthguard. Mouthguards work by dissipating the force of impact, thus reducing the force which is transferred to the dentition. There are different types of mouthguard available which vary in design, costs and the level of protection provided. This article aims to review the use of mouthguards in sport, the common barriers to their use and also the different types of mouthguards and their characteristics...

Orofacial injuries are common in sports activities and may vary in complexity and the tissues involved. Most sports-related trauma occurs when a player hits another player, an object or the ground. This report presents a case of an injury caused by a punchlike blow to the face during a handball college team practice session. The patient suffered a traumatic blow to the left side of the nose and mouth and promptly attended a dentist. After a clinical examination and a CBCT scan, the following injuries were diagnosed: upper lip laceration, upper left lateral incisor subluxation and anterior nasal spine fracture...
