Effect of Infection on Healing of Skeletal Muscle Injury: An In Vivo Study.

infection has been associated with various systemic diseases and may cause delayed healing of muscle injury. However, the relationship between muscle injury healing and infection remains unclear. Our hypothesis was that infection delays the healing of muscle injuries.

Quantitative text analysis of the mechanisms of tooth injury: Analysis of accidents in five sports that occurred in 15 years under school control.

Background/aim: Dental trauma may occur in school settings and it can impact patients' quality of life. Analysis of the occurrences of dental trauma is essential in identifying preventive methods. There are numerous reports of such accidents but most are quantitative analyses with limited data.

Continuous Oral Administration of Sonicated Delays Rat Skeletal Muscle Healing Post-Treadmill Training.

Background: A delay in muscle repair interferes with the effect of training or exercise; therefore, it is important to identify the factors that delay muscle repair. , one of the most common periodontal disease pathogens, has the potential to inhibit muscle repair after training, as inferred from a previous study. To assess the expression of satellite cells in this in vivo study, we evaluated the relationship between and muscle regeneration after training.

Useful design of custom-made mouthguard for athletes undergoing orthodontic treatment with brackets and wires.

Background/purpose: Custom-made mouthguards (MGs) are strongly recommended for athletes during sports activities to prevent dental injuries. Athletes undergoing orthodontic treatment and wearing brackets require specially designed MGs for better protection and to create more space that will not hinder the planned orthodontic tooth movement. The purpose of this study was to fabricate effective, specially designed, custom-made MGs for patients or athletes with ongoing orthodontic treatment and to evaluate the shock absorption abilities of these MGs by an comparison of three different designs.

Antibacterial effect of a disinfectant spray for sports mouthguards on .

Background: Mouthguard (MG) disinfectant sprays are available for maintaining MG hygiene. The effect of these sprays against is still unknown. The purpose of this study was to evaluate the antibacterial effect of an MG disinfectant spray against using the modified ISO 22196 standard.

Development of a Wearable Mouth Guard Device for Monitoring Teeth Clenching during Exercise.

Teeth clenching during exercise is important for sports performance and health. Recently, several mouth guard (MG)-type wearable devices for exercise were studied because they do not disrupt the exercise. In this study, we developed a wearable MG device with force sensors on both sides of the maxillary first molars to monitor teeth clenching.

Thickness change and deformation of custom-made mouthguards after two years of use by Bangladeshi field hockey players.

Background/aim: Sports mouthguards are effective devices that prevent dental trauma in sports activities. Players should change mouthguards on a regular basis because of thickness reduction and shape deformation. However, there is no guidance regarding the best timing to change mouthguards.

Effectiveness of computer-assisted learning in sports dentistry: studies over a multiple-year period and at two universities.

Introduction: Insufficient educational resources on sports dentistry result in varying lecture implementations across dental schools, which cause knowledge gaps amongst students. Thus, a new interactive sports dentistry-related computer-assisted learning (CAL) module was created to facilitate dental school undergraduate students' education. This study compared the CAL module's learning effectiveness with conventional video lectures (VL) and assessed its effectiveness when used over several years at a university, and examined its validation in different university contexts, and students' perceptions.

Fabrication technique of obturator-type sports mouthguard for a patient who had undergone maxillectomy and its speech intelligibility assessment:A case report.

Purpose: Wearing a sports mouthguard is not only recommended in collision sports, such as American football, boxing, and rugby football, but also in low-contact sports, such as basketball, handball, and soccer. It is recommended to remove oral prosthetic devices while playing sports to avoid the risk of fracturing the device. However, players with maxillectomy must wear obturator-type prosthetic devices for speech, breathing, and deglutition even while playing sports.

Improving the Wearing Rate of Mouthguards in the Youth Rugby Category Affects the Total Future Mouthguard Wearing Rate.

The aim of this study is to consider the hypothesis that wearing mouthguards (MGs) from a young age helps to shape players' habit of continuing to wear MGs as adults. In addition, we consider the mandatory rule of wearing mouthguards in the youth category on the future wearing rates of mouthguards. Eighty-five Japanese male amateur rugby players were included in this study.

The facilitatory effects of hyperbaric oxygen treatment on membrane bone wound healing in a rat calvarial defect model.

We examined the effect of hyperbaric oxygen (HBO2) treatment on bone wound healing in a rat calvarial defect. Critical-sized defects were created in the calvaria of adult Wistar rats. The animals were divided into four groups--HBO2, normobaric oxygen, hyperbaric air, and no treatment.
