Patient with alveolar abscess due to dental caries with severe alveolar bone loss, severe tooth mobility, root resorption need extraction of tooth because it is impossible to carry out pulp treatment and restoration by using conventional method. Early loss of primary molar might cause masticatory interference, extrusion of opposing tooth, problem in maintaining space and interference on eruption of permanent tooth. Especially, early loss of primary second molar before the eruption of permanent first molar might cause space closure by mesially erupted permanent first molar and impaction of second premolar. In such a case, distal shoe space maintainer and removable space regaining appliance was the first choice of treatment. But, distal shoe space maintainer need precise adaptation and might cause chronic inflammation if the oral hygiene is poor. In a case using removable space regaining appliance, patient's cooperation is most important. If the distal root of primary second molar is comparably sound and alveolar abscess with alveolar bone loss is localized at mesial root, hemisection should be carried out for precise guide to eruption of the permanent first molar, restoration of masticatory fuction and solution to the discomfort of the patient

The bunionette, or a 'tailor's bunion', is a lateral bony prominence of the fifth metatarsal head. A bony deformity itself rarely causes symptom but if a painful inflammation of the overlying soft tissue is accompanied, it needs treatment. Conservative care using a shoe modification, padding, or orthosis is effective in most cases. Surgical management is indicated when the conservative methods have failed to improve symptoms, and the techniques include exostectomy, metatarsal osteotomies (distal, diaphyseal, or proximal), metatarsal head resection or fifth ray resection. We reviewed the etiology, clinical features, radiographic classification, nonoperative and operative treatments of the bunionette.

20 years old female patient with asymmetric mandibular prognathism had anterior openbite, anterior cross-bite and mandibular shift. This patient was treated with both orthodontic and surgical method. Maxillary second molars were extracted to reduce the wedging effect and maxillary first molars moved to distal by straight pull head gear. After orthognathic surgery, open-bite was corrected with multiple shoe-loop arch wire.

Early loss of a primary second molar can cause mesial drift or tilting of the permanent first molar. We present a case of the early loss of the mandibular primary molars in a 5-year-old girl. The patient required extraction of the mandibular left primary first and second molars due to folliculitis on the successors. A flexible denture was used for eruption guidance of the permanent first molar and the recovery of masticatory function simultaneously.

In order to study the foot deformity hallux valgus, the rate of which is currently increasing, 235 patients who were diagnosed with hallux valgus and treated in an orthopedic hospital in Seoul had their feet calibrated before and after surgery using 3d radio-scans. Data from 209 cases was analyzed and scored numerically. We scored 10 items for length, 4 for width, 3 for angle, and 2 for height, for a total of 20 items. Each individual's feet showed great variation in most of the items and significant differences after surgery, especially in regards to length and height, which increased after surgery. Angle, width, and length of the distal parts of the toes decreased after surgery. Based on the results of our analysis, we conclude that surgery brings about significant changes in structure and measurement of feet. This research confirmed that there is significant variation in foot form and individual differences based on lesion size and location and, thus, it is difficult for hallux valgus patients to find ready-made shoes that fit them properly. Foot changes before and after operation for hallux valgus were analyzed and the results quantified; our results should be considered during product design by shoe companies whose target is adult women.
