Objective: The aim of this study was to establish the normative data of dentofacial transverse dimensions according to the skeletal maturation stage in Korean adolescents with good occlusion, assess gender differences and determine correlations between transverse variables. Methods: A total of 577 Korean subjects between ages 7 to 19 years and exhibiting skeletal Class I occlusion were categorized by skeletal maturation index (SMI) of Fishman using hand-wrist radiographs. Dentofacial transverse dimensions were assessed using posteroanterior cephalograms. Independent two-sample t-tests were used to analyze differences between genders. Pearson correlation coefficient was used to determine the correlation between transverse measurements. Results: Dentofacial transverse norms relevant to skeletal maturation stages were esta-blished. The average maxillomandibular width difference and ratio at growth completion was 22.16 mm and 77.01% for males; 23.70 mm and 74.06% for females, respectively. Males had greater facial, maxillary and mandibular widths compared to females at every SMI stage. The maxillary and mandibular intermolar widths showed the strongest correlation for both sexes (r = 0.826 for males, r = 0.725 for females). Conclusions: Den tofacial transverse norms of Korean adolescents were established according to developmental stage. All de ntofacial widths were greater in males at growth completion. Maxillary and mandibular intermolar widths were strongly correlated. This study may serve as a guideline for the assessment of dentofacial transverse growth according to skeletal maturation stage in Korean adolescents with good occlusion.[Korean J Orthod 2018;48(1):39-47]

정상적으로 자연 분만한 Cocker spaniel 개 8두를 대상으로 분만 후 자궁의 수복상태를 관찰하기 위하여 육안적 질 분비물의 배출 및 초음파 진단장치를 이용하여 자궁의 형태, 에코 정도 및 크기의 변화상 등을 검사한 바 8두 모두 자궁의 수복이 정상이었다. 분만 후 자궁의 형태는 초음파 종단면에서 착상부가 비착상부에 비해 종대되어 나타나는 염주상을 보였으나 분만 후 25.602.51일 이후에는 착상부와 비착상부가 유사한 크기인 관상으로 관찰되었다 This study was undertaken to determine the normal appearance of the postpartum uterine involution. Postpartum changes in uterine shape, architecture, echogenicity and diameter were monitored with ultrasonography in 8 Cocker spaniel bitches. The excretory period of vaginal discharges in 8 normal bitches of uterine involution was finished completely at 23.202.77 days (MeanSD) postpartum. The short axis shape of the uterus was varied from polygonal to circular. This lasted until 16002.12 days Postpartum, during which time the short axis uterine shape gradually changed to circular. Also, the long axis shape of the uterus was created a beaded appearance of the horns until 25.602.51 days postpartum. The uterine diameter was decreased not only in the placental sites from 24.202.06mm at 1 day to 13.180.84mm at 7 days postpartum, but also in the interplacental sites 14.262.22mm at 1 day, 9.810.7mm at 7 days postpartum. There was a general trend of decreasing uterine diameter, which occurred more rapidly at the placental sites. In conclusion, normal postpartum uterine involution in Cocker spainel bitches appeared to be completed around 68 days postpartum by gross findings such as vaginal discharges, and by ultrasongraphic findings, uterine shape and echogenicity.

A 9 year-old male Maltese with dysuria, pollakiuria, and stranguria was brought to the Veterinary Teaching Hospital, Chonnam National University. A right lateral abdominal radiograph was shown that 3 uroliths existed at the caudal aspect of the os penis and 5 uroliths existed in the passage of os penis. Uroliths were extracted by voiding urohydropropulsion and cystotomy in Maltese dog. The complication of cystotomy was hematuria, which might persist up to 2 days postoperatively but dysuria was not observed. So we applied voiding urohydropropulsion and cystotomy, and got a good prognosis. Gross examination of extracted uroliths were separated one from another but it was identified the same componet of calcium oxalate by stone quantitative analysis.

Prophylactic removal of impacted third molars is a common procedure in dentistry, but the necessity of routine extraction is still controversial. When impacted third molars caused severe apical root resorption of the second molars, orthodontic traction of the third molars after extraction of the damaged second molars could minimize alveolar bone defect and preserve the patient’s natural teeth. By well-planned orthodontic treatment, functional occlusion was established avoiding extraction of the impacted teeth and eliminating the possibility of a large bone defect after extraction.

A 4 year old mixed female dog was presented dyspnea, anorexia and syncope. In blood smear test, a lot of heartworm larvae were observed. In thoracic radiography, "reverse D" shape was observed. So, this case was considered with heartworm disease. In echocardiography, marked left heart hypertrophy was presented. In M-mode view, aortic valvular stenosis was found. After mongrel dog died, aortic valvular stenosis was reconfirmed in necropsy. After all, the dog died of pulmonary edema because of aortic valvular stenosis caused left heart failure.

We report the rehabilitation of Class II malocclusion with multiple teeth fracture due to trauma. A multidisciplinary team approach was necessary to treat patient’s problems such as bone fracture, malocclusion, and multiple teeth fracture. Emergency conservative treatment, orthodontic treatment and prosthetic restoration successfully restored the occlusion. However, special considerations were needed along the orthodontic treatment process due to the unexpected complications such as ankylosis, root resorption and detection of additional teeth fractures.

Serial ultrasonographic examination was daily performed on 12 pregnant Shih-tzu bitches from day 15 until parturition to determine the size of gestational structures. Gestational age was timed from the day of ovulation (day 0), which was estimated to occur when plasma progesterone concentration was first increased above 4.0 ng/ml. Extrafetal structures were measurable from days 17 to 46. Outer uterine diameter increased from 9.90.4 mm (MeanSD) at day 20 to 44.30.8 mm at day 46 and inner chorionic cavity diameter increased from 7.20.2 mm at day 17 to 36.91.5 mm at day 41. Length of chorionic cavity or zonary placenta increased from 6.60.4 mm at day 21 to 46.4 0.9 mm at day 44. Of the extra-fetal structures, inner chorionic cavity diameter was the most accurate for estimation of gestational age until day 38. Fetal structures were measurable from days 23 to 60. Crown-rump length increased from 3.90.3 mm at day 23 to 55.23.3 mm at day 41, fetal body diameter increased from 7.90.6 mm at day 32 to 47.82 mm at day 60, and fetal head diameter increased from 6.31.1 mm at day 29 to 25.60.2 mm at day 60. Of the fetal structures, fetal head diameter was the most accurate for estimation of gestational age from day 38 until day 60.
