kn-title=Comparison of Oxygen Saturation Between Nasal High-Flow Oxygen and Conventional Nasal Cannula in Obese Patients Undergoing Dental Procedures With Deep Sedation: A Randomized Crossover Trial
en-subtitle=

kn-abstract=Purpose:<br>
In anesthetic management, it is widely accepted that obese patients are more likely to suffer airway obstructions and reductions in arterial oxygen saturation (SpO2). Therefore, it is important to take special measures to prevent oxygen desaturation during the deep sedation of obese patients. This clinical study examined whether the use of nasal high-flow systems (NHFS) keep higher SpO2 and reduced hypoxemia than conventional nasal cannula during the deep sedation of obese patients with intellectual disabilities for dental treatment.<br>
Materials and Methods:<br>
Eighteen obese patients (body mass index: >25) with intellectual disabilities who underwent dental sedation were enrolled. In each case, sedation was induced using propofol and 
 maintained at a bispectral index of 50–70. The subjects were randomly assigned to the control oxygen administration (5 L/min via a nasal cannula) or NHFS (40% O2, 40 L/min, 37°C) arm in alternate shifts as a crossover trial. The primary endpoint was the minimum SpO2 value, and the incidence of hypoxemia during dental treatment was also evaluated.
Results:
The mean minimum SpO2 value was significantly higher in the NHFS arm than in the
4
control arm (95.8 ± 2.1 % vs. 93.6 ± 4.1 %, p=0.0052, 95% confidence interval: 0.608–3.947). Hypoxemic episodes (SpO2: ≤94%) occurred 3 cases (16.7%) in the NHFS arm and 11 case (61.1%) in the control arm (P=0.0076, odds ratio: 0.127, 95% confidence interval 0.0324 to 0.630).
Conclusion:
NHFS resulted in higher minimum SpO2 and reduced hypoxemia than nasal cannula in obese patients during deep sedation for dental treatment

kn-title=Chronic Orofacial Pain in Dental Patients: Retrospective Investigation over 12 years
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Orofacial pain is often difficult to diagnose and treat. However, there have been few reports on the clinical observation of dental patients with orofacial pain. We retrospectively investigated the characteristics of 221 dental patients who had suffered from persistent orofacial pain. Data were collected from the outpatient medical records in our clinic over the past 12 years. More than half of the patients (53.8%) had suffered with pain for more than 6 months from pain onset until the first visit to our clinic. The main diagnoses were neuropathic pain (30.3%), myofascial pain (23.5%), psychogenic pain (20.4%), odontogenic toothache (17.2%), and others (7.7%) such as temporomandibular disorders and glossitis. The treatments included pharmacotherapy, splint therapy, and others such as nerve block, dental treatment, physiotherapy, and/or psychotherapy. Excluding the patients (52 of 221 initially enrolled patients) with unknown responses to treatment, 65.7% showed remission or a significant improvement in pain in response to treatment. Although only a small group of patients had odontogenic toothache, the rate of improvement was highest for this disorder. In conclusion, early consultation with a dentist is useful to prevent chronicity of odontogenic pain and to make a differential diagnosis in patients with orofacial pain.
