This study assessed subjective sleep quality, the Respiratory Event Index (REI), reaction times, and the therapeutic effects of a custom-made mandibular advancement device (MAD) in male Japanese elite rugby athletes. The Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale (ESS), and level III sleep test (REI and minimum oxygen saturation [SpO2 min]) were used to evaluate sleep quality. MAD therapy was used daily for 3 weeks. A telephone-based reaction time test of kinetic vision (the ability to identify moving objects) was recorded within 15 min of waking and over 5 days of pre- and post-MAD therapy. Differences in variables were evaluated using paired t-tests. Of the 42 players (mean age, 26.3 ± 3.7 years; mean body mass index, 28.7 ± 3.2 kg/m2) included in this study, 29 (69.0%) had poor sleep quality (PSQI > 5.5), and 27 were diagnosed with OSA (64.3%) (mild = 16/moderate = 9/severe = 2). Six were ...

This study evaluated airflow rates of our newly designed nasal breathing stent (NBS) compared with those of existing nasal dilators in 10 adult men. We hypothesized that the NBS would expand the nasal passage more than the other nasal dilators by means of airflow measurements. We compared airflow measurements between the NBS and three existing appliances and no appliance. Velocity measurements were recorded by analyzing 499 videographic images when each appliance was placed next to a steam generator at 0, 5, and 10 mm from the outlet port for airflow visualization. The peak nasal inspiratory flow (PNIF) rate was measured using an inspiratory flow meter. The NBS resulted in significantly higher airflow velocity measurements at all distances from the outlet port and a higher PNIF rate than the other appliances. Thus, the NBS offers a significantly decreased resistance to air movement ...

Rhinomanometry, the gold standard technique to assess nasal airway resistance, is not readily available in sleep dentistry clinics. We demonstrate the use of a portable lightweight peak nasal inspiratory flow (PNIF) rate meter to objectively assess nasal airflow and utilized the Nasal Obstruction Symptom Evaluation (NOSE) scale to subjectively assess nasal obstruction in 97 patients with OSA and 105 healthy controls. We examined the correlations between the following variables between the groups: demographics, body mass index, PNIF, NOSE scale scores, apnea–hypopnea index (AHI), minimum SpO2 (SpO2min), Mallampati classification, and Epworth Sleepiness Scale (ESS) scores. Patients with OSA had significantly lower PNIF values and higher NOSE scores than controls. In the patient group, PNIF was not significantly correlated with AHI, SpO2min, Mallamp...

This study investigated the severity of obstructive sleep apnea (OSA) and body composition among Japanese rugby union players. Methods: Subjects were 52 Japanese male rugby union players. The team received routine dental support at the Nihon University School of Dentistry in Matsudo, Japan. Dental services included dental checkups and treatment, and provision of custom-made mouthguards. Outcome measures were the respiratory disturbance index (RDI) recorded from a sleep apnea test and body mass index (BMI), neck circumference (NC) measurements, and the Epworth Sleepiness Scale (ESS). All players were informed of the outcome of the sleep apnea test following completion of assessments, after which eight players desired and received treatment with a monoblock mandibular advancement device (MAD). Results: OSA was seen in 86.5% of play...

Oral diseases can decrease their performance by affecting their concentration during games and practice sessions. Appropriate education is therefore required regarding the importance of dental support. We introduced periodic dental examinations and fabricated custom-made mouthguards (CMGs) for athletes with cerebral palsy (CP). This study aimed to determine the effects of wearing a CMG on masticatory muscle activities in CP athletes while measuring center of gravity (COG) sway. Materials and Methods: Thirteen athletes with CP (male, n=12; mean age, 27.3 ± 8.96 y) and 10 healthy male controls (mean age, 28.5 ± 1.35 y) participated in the present study. The CMG comprised 2-mm-thick polyolefin sheeting. All participants underwent dental checks and occlusal contact areas were measured with and without a CMG. We simultaneously measured gravitational sway at the COG with the eyes open, as well as masticatory (masseter and digastric) muscle activities with or without a CMG. Data were statistically analyzed using two-way mixed analyses of variance. Results: Indices for decayed, missing and filled teeth did not significantly differ between athletes and controls. However, the occlusal contact area significantly increased in athletes when wearing a CMG. Although COG sway slightly differed between having eyes open and closed in athletes, masticatory muscle activity increased and COG sway decreased. Conclusion: The findings suggest that wearing a CMG might change the modality of masticatory muscle activity in athletes with CP and might help to improve balance during static exercise.
