This study investigated the prognosis of luxation injuries in primary teeth treated with splinting. This study retrospectively analyzed 92 children with luxation injuries to their primary teeth who were treated with splints between 2010 and 2015. Prognoses were analyzed in patients who had been followed for more than 6 months. The prognoses with splinting were based on clinical and radiographic evaluations performed during the follow-up examinations. The mean patient age was 42.1 months, and 67.4% were male. The most common cause of luxation injury was falling, and the mean splint duration was 2.4 weeks. The success rate of splinting was 58.9%. The highest rate of success was achieved following subluxation, while repositioning and splinting of lateral luxation had the lowest rate of success. Pulp necrosis was the most common unfavorable prognosis in the luxation injuries. Depending upon the type of luxation, splint therapy had acceptable prognoses and might be a feasible treatment option.

A traumatic dislocation of the sternoclavicular joint is a rare injury, and among them, anterior dislocation is more common than a posterior dislocation. Posterior dislocation is a potential risk by compressing the mediastinal structures, but an anterior dislocation has not been considered a risk. Traumatic sternoclavicular joint anterior dislocation associated with anterior angulation of a sternal fracture can develop mediastinal compression and have a risk in the same way as a posterior dislocation. This case report is about a traumatic sternoclavicular joint anterior dislocation with a sternal fracture accompanied by mediastinal compression that was treated surgically using a plate and showed relatively good clinical results. This rare case is reported along with a review of the relevant literature.

외상성 전방탈구의 경우 일차성 탈구이거나 일상생활에 큰 불편을 호소하지 않는 불안정성이 있을 경우 및 비외상성 다방향 불안정성의 경우 보존적 치료가 바람직하며, 10대 및 20대의 재탈구로 인한 불안정성이 유발될 경우 관절경적 혹은 개방성 Bankart 술식을 통하여 관절순의 해부학적 정복 및 술 후 잘 조절된 재활치료를 시행할 경우, 좋은 결과를 얻을 수 있다. 치료 방법의 선택 시 가장 중요한 요소는 환자의 원하는 결과를 만족 시켜줄 수 있는 치료 방법을 선택하는 것이며, 이는 불안정성의 원인, 정도, 탈구의 횟수, 환자의 활동도 및 재활 의지등을 종합적으로 감안하여 결정되어야 한다.

견관절 전방 탈구의 치료 방법을 결정하는데 있어서 중요한 점은 탈구를 유발한 병태 생리에 대한 충분한 숙지와 함께 적절한 환자의 선택과 치료 결과에 대한 환자의 기대치를 파악하여 그에 맞는 치료를 선택하는 것이 중요하다. 탈구의 횟수에 있어서 첫 탈구이거나 아주 적은 횟수의 탈구로 환자가 일상 생활에 어려움을 호소하지 않는다면 보존적 치료를 시행해야 할 것이며, 수술적 치료의 경우에 환자의 병변 상태나 그 원인 인자에 대한 평가가 정확히 이루어진 후 시행되어야 한다. 환자의 기대치는 일반인의 경우 수상 이전의 활동도의 회복보다는 안정성이 중요할 것이며, 운동 선수인 경우에는 안정성이 회복 되었더라도 운동에 다시 복귀하지 못한다면 만족도는 매우 떨어질 것이다. 이렇듯 의사의 능력이나 욕망 보다는 환자의 활동 정도와 견관절의 병적 상태, 환자의 요구에 맞는 치료방법을 선택해야 할 것이다.

This study aims to identify the factors that affect customer satisfaction as the market growth of rental subscription services for living environment home appliances increases. Unlike previous research, which focused on online subscriptions (e.g., digital content, over-the-top (OTT) services, e-books, and mobile devices), this study expands the scope to include rental subscriptions for household environmental appliances. Specifically, this study analyzes the factors influencing customer satisfaction among rental subscription service users by examining the effects of perceived usefulness, reliability, and convenience. The results show that users' perceived reliability and convenience of rental subscription services for living environment home appliances significantly affect customer satisfaction. Perceived usefulness, however, was not found to have a significant impact, as it is an abstract and subjective customer aspect. The implications of the results are as follows: First, standardized services must be strengthened to increase the reliability of rental subscription services. Additionally, it is necessary to improve convenience by developing additional services when managing regular visits tailored to the characteristics of each product. Providing customized services by integrating products and Information and Communications Technologies (ICT). Furthermore, effective customer management to increase customer satisfaction is crucial, as it can lead to cross-selling and up-selling opportunities. Lastly, venture start-ups should actively apply a subscription service business model.

손상에 의한 치근 흡수는 표면 흡수(surface resorption), 염증성 흡수(inflammatory resorption) 및 대치성 치근 흡수(replacement resorption)가 있는데 치근 흡수의 정도는 탈구와 재식 사이의 시간, 치주 인대의 손상 정도, 탈구된 치아의 보관 조건 및 치아 발육 정도 등에 영향을 받는다.(중략)

Hill-Sachs lesion is the most common lesion in shoulder dislocation patient and it represented by postero-lateral bony defect of humerus. The lesion could be found in patients who dislocate shoulder joint first time, and it is reported that Hill-Sachs lesion proportionally increases as dislocation does. The location and presence of Hill-Sachs lesion play significant roles in shoulder instability. Authors experienced a double Hill-Sachs lesion in a recurrent anterior shoulder dislocation patient, and thereby report the case with a review of the literature.

Dislocation of the temporomandibular joint (TMJ) occurs when the mandibular condylar head is displaced completely out of the glenoid fossa and cannot be reduced by the patient. The occurrence of bilateral anterior dislocation is the most common. Dislocations can be classified into three types in terms of duration and frequency of dislocation, i.e., acute, chronic and recurrent. There are various treatment modalities for dislocation from conservative try to surgical intervention. The selection for the appropriate modality mainly depends on the types of dislocation as previously stated. The authors report three cases of dislocation with different treatment modalities according to the duration of dislocation. In particular, we tried prosthetic approach instead of surgical intervention in the patient with chronic dislocation.

Traumatic injuries to immature permanent teeth are common and the results can be destructive. Although Hertwig's epithelial root sheath is usually sensitive to trauma, it may resist damage from trauma thereby retaining its vitality and continuing to calcify a root under favorable conditions. This case report describes two cases of trauma to immature permanent incisors. The first case presents an avulsed maxillary central incisor which has been replanted. The other case shows completely avulsed mandibular central incisors which have not been replanted. However, both cases subsequently show continued growing roots separated from the main roots. This report highlights the ability of the immature pulp tissue to continue to form dentin and the robustness of Hertwig's epithelial root sheath to initiate root development despite a traumatic injury.
