歯科矯正用アンカースクリューを用いたアングルI級上下顎前突症例
Get PDFapplication/pdfThe report describes orthodontic treatment of a 37 years 7 months old female patientwith Angle Class I and bimaxillary protrusion using temporary anchorage device (TAD).The antero–posterior skeletal relationship was skeletal Class II. The upper and lower incisorswere labially inclined and molar relationship was Angle Class I. The treatment objectives were correction of labial inclination of upper and lower incisors with extraction of theupper and lower first bicuspid using TAD. The upper arch wire with molar tip back bend was fixed at the upper second bicuspid from TAD during the retraction of canine and anteriorteeth. As a results of the treatment for 2 years and 10 months, upper and lower anteriorteeth showed lingual bodily movement and mandible rotated counterclockwise with the depress of upper anterior and molar teeth. On the other hand, the upper molar showed moderate anchorage with the mesial movement and depress of upper molar teeth due to tip back bend.In summary, orthodontic treatment using TAD and arch wire with tip back bend at molar make it possible for the lingual bodily movement of anterior teeth and the depression of upper anterior and molar teeth.journal articl

静脈麻酔下における歯科処理時のプロポフォール投与量の増加要因
Get PDFapplication/pdfIntroduction Dental treatment using propofol (trade name Diprivan) was carried out for people with disabilities who have difficulties with dental treatment so that dental treatment could be carried out safely and smoothly. This time, we investigated for the purpose of clarifying the factors of those who need 3.5 µg/ml or more when sedated with propofol. Object and method Methods The subjects were 34 persons, who required the intravenous anesthesia method at the time of dental treatment, among patients who visited Matsumoto Dental University Hos-pital special specialist department from May 1st to September 30 th , 2015. Gender, age, presence or absence of regular medications were noted, weight and height were measured, and BMI was calculated. Disease, treatment, type of disability, and intellectual level from the medical record were entered on the survey form. As an evaluation of adaptability to dental treatment, they were classified into 4 stages: “Can sit on the medical table”; “Can sleep the treatment table”; “Can do an oral examination”; and “Can do PTC”. The diffuser TCI function was used to initiate intravenous administration at the target blood concentration of 3.0 µg/ml. Dental treatment was started with blood concentration in the brain when the opening device was smoothly inserted. If this target was not possible, 0.2 µg/ml each was listed. Blood concentrations and intracerebral concentrations of propofol during treatment were recorded. The intracerebral concentration where the opening device was smoothly inserted, the lowest brain concentration and the maximum brain concentration at the time of treatment were also recorded.Result 34 subjects (28 males, 6 females) had an average age of 37.6±12.4 years. The items asso- ciated with brain concentration of propofol were subjects aged 50 years or older (P = 0.01), BMI (P = 0.15), dental phobia (P = 0.001), and autistic spectrum disease (P = 0.07). The factor that required propofol brain concentration of over 3.5 µg/ml was dental phobia (odds ratio: 28.5: confidence interval 1.₉–421) by the logistic regression analysis. Conclusion A factor that requires propofol of 3.5 µg/ml or more at the time of dental treatment, for those who can assume a supine position without making refusing actions at the medical table, was dental phobia. There was no relevance to the content of treatment or to the adaptability to dental treatment.journal articl
The Relation of Pain Value and Touch Threshold of Patient with Trigeminal Neuralgia-The Effect of Gamma Knife Stereotactic Radiosurgery
Get PDFapplication/pdfTrigeminal neuralgia (TN) is a chronic neuropathic pain disorder that makes daily life difficult. Recently, gamma knife surgery (GKS) has been employed for treating intractable pain control such as trigeminal neuralgia (TN) or cancer pain. Nine patients (4 males and 5 females) with TN of second branch were investigated in this study. All patients (mean age: 66.7±7.5) were irradiated a maximum dose of 90 Gy at retro Gasserian after the target area were coordinated with magnetic resonance imaging (MRI) and computed tomography (CT). They were asked symptom, medical history and what induces the pain attack. We also assessed visual analog scale(VAS) of pain, presence or absence of allodynia, cold sensation dullness and touch threshold on the lateral of nasal wing using Semmes-Weinstein monofilaments before and 1, 3, 6, and 12 months after GKS. The relation of the pain value and touch threshold were estimated. There were two kinds of pain character, like an electric shock (5 patients) and like prickling (4 patients). The mean±SD of pain VAS value was 8.5±1.4 and touch threshold on disease side (6.0±2.8 gf/mm2) was significant higher than the healthy side (3.7±1.3 gf/mm2) at first visiting (paired t-test; P<0.05). All patients experienced asignificant pain reduction without side affections within 6 month after GKS. Allodynia, facial paresthesia or cold sensation dullness occurred before GKS disappeared within 3 touch threshold. These results suggest that GKS is safe and effective method to let a pain and dysesthesia due to TN disappear. There are individual differences in these effect after treatment.journal articl
