This study aimed to identify sub-dimensions of the authenticity and fictionality of a brand story and analyze the effects of authenticity and fictionality on customer-based brand equity. Data were obtained from a group of 213 males and females in their 20s and 30s living in Korea using an online survey institute. Results showed that the authenticity and fictionality of a brand story are composed of reality, excitement, exaggeration, fictional symbolism, influence, sincerity, relativeness, mysteriousness, and unreality. Of these, sincerity, excitement, reality, influence, and mysteriousness had significant effects on brand imagery; sincerity particularly exerted a relatively more substantial influence on brand imagery. Also, influence, mysteriousness, excitement, and relativeness impacted performance positively, and exaggeration impacted performance negatively. This indicated that a well-constructed brand story with authenticity and fictionality had a positive impact on the brand image. Excitement, mysteriousness, reality, relativeness, sincerity, and influence of a brand story had significant effects on brand judgement. In contrast, only excitement and influence positively impacted brand feelings, and unreality had a negative impact on feelings. The exciting and influential brand story impacted brand attitude. Also, brand image and attitude positively impacted sharing and purchase intention, while brand performance did not affect recommendation intention. These findings contribute to identifying a brand story's attributes, authenticity, and fictionality and provide insights for marketers on creating brand stories to increase brand image and attitude and to build customer-based brand equity.

Background: Pain, edema, and trismus are predictable sequelae for surgical extraction of impacted mandibular third molars (M3M). The present study aimed to compare the anti-phlogistic potential of bromelain and aceclofenac in the reduction of post-surgical sequalae in the extraction of impacted M3M. Method: A randomized controlled, triple-blinded clinical study included 72 patients scheduled for surgical removal of impacted M3M under local anesthesia. Randomization was performed and subjects were equally allocated to groups A (control) and B (study), who intended to receive aceclofenac and bromelain, respectively. The primary outcome variables were pain, edema, and trismus evaluated on postoperative days 2 and 7 and compared with baseline values. The secondary variables evaluated were the quantity of rescue analgesics required and the frequency of adverse effects in both groups for 7 postoperative (PO) days. Data were analyzed with a level of significance of P < 0.05. Results: Group B demonstrated a significant decrease in the severity of edema and trismus compared to group A on both PO days 2 and 7 (P < 0.001). Bromelain demonstrated similar analgesic efficacy with an insignificant difference compared to aceclofenac (P > 0.05). Conclusion: The present study showed that the efficacy of bromelain was comparable to that of aceclofenac in reducing inflammatory complications following surgical removal of impacted M3M. Bromelain can be considered a safe and potent alternative to routinely used aceclofenac when addressing inflammatory outcomes after surgery.

Purpose: This study aimed to evaluate the anatomic circle around the impacted lower third molar to show, document, and correlate essential findings that should be included in the routine radiographic assessment protocol as clinically meaningful factors in overall case evaluation and treatment planning. Materials and Methods: Cone-beam computed tomographic images of impacted lower third molars were selected according to specific inclusion criteria. Impacted teeth were classified according to their position before assessment. The adjacent second molars were assessed for distal caries, distal bone loss, and root resorption. The fourth finding was the presence of a retromolar canal distal to the impaction. Communication with the dentist responsible for each case was done to determine whether these findings were detected or undetected by them before communication. Results: Statistically significant correlations were found between impaction position, distal bone loss, and detected distal caries associated with the adjacent second molar. The greatest percentage of undetected findings was found in the evaluation of distal bone status, followed by missed detection of the retromolar canal. Conclusion: The radiographic assessment protocol for impacted third molars should consider a step-by-step evaluation for second molars, and clinicians should be aware of the high prevalence of second molar affection in horizontal and mesioangular impactions. They also should search for the retromolar canal due to its associated clinical considerations.

Pressure root resorption can be observed during the eruption of permanent dentition, especially of the maxillary canines (affecting lateral incisors) and mandibular third molars (affecting mandibular second molars). Since the cause of root resorption of the adjacent affected teeth is evident, treatment simply involves extraction of the impacted tooth. However, there have been few reports on the prognosis of the remaining resorbed tooth, as dentists often choose to extract them when damage due to root resorption is observed. We report a case involving a tooth that was severely resorbed due to pressure from an adjacent impacted tooth. After extraction of the impacted tooth, the remaining tooth retained vital pulp and survived as a functional tooth.

We present two cases of multiple jaw cysts not associated with basal cell nevus syndrome. Case 1: a nine year-old boy visited CNU Hospital for orthodontic treatment and his radiographs showed cystic lesions surrounding the crowns of teeth #13 and #17 respectively, which were diagnosed as dentigerous cysts. Subsequently, two more cysts were found on his follow-up radiographs in 12 and 15 months. The two cysts were determined to be odontogenic keratocysts. The boy had no skeletal abnormalities and no skin lesions associated with basal cell nevus syndrome. Case 2: a fifty-eight year old man had three impacted third molars with pericoronal radiolucencies, which were diagnosed as dentigerous cysts. He had no additional abnormalities associated with basal cell nevus syndrome. Multiple jaw cysts can occur at any age, and periodic radiographic surveillance may be needed for any cases of impacted tooth.

In this study, an analysis technique using simple beam model for predicting structure crashworthiness of the passenger car side impacted with an angle by another passenger car was investigated. The simple model was composed of major beam-like side structure which carry almost all side impact load. A procedure of component collapse test, calculation of load carrying capability and dynamic simulation was carryed out sequentially. Transient dynamic algorithms and a computer program to simulate deformations and motions of the impacted car was developed. The developed procedure was applied to a 3 door passenger car side impacted with an angle of 75 degree and the analysis results show good agreements with the actual test results.

Etiologies of the molar teeth impaction are cyst, supernumerary teeth, ankylosis by replacement resorption, abnormal eruptive path, improper orthodontic treatment, etc. If the impacted teeth were untreated, the sequallae was as follows : loss of occlusal function, loss of permanent tooth, extrusion of opposite tooth, root resolution of adjacent teeth. The most important factor of solution of impacted teeth is treatment timing & proper application of orthodontic forces.

Transmigration of an impacted tooth through the symphyseal suture is a rare and special developmental anomaly of unknown etiology that is unique to the mandibular canine. Maxillary canine transmigration is even rarer. Transmigrated canines are particularly significant due to the aesthetic and functional importance. A maxillary lateral incisor crossing the mid-palatal suture has never been reported in the literature. The aim of this report is to present the first case of simultaneous transmigration of a lateral incisor and canine in the maxilla. The paper also reports four unusual cases of unilateral canine transmigration in the maxilla and mandible and successful eruption of one of the transmigrated mandibular canines following orthodontic traction. Etiology of transmigration and its clinical considerations are also discussed.

The author has studied on extraction of the impacted lower third molar in terms of incision A designed by author, Extraction of those teeth is one of the critical problems involving all dentists and oral surgeons in connection with their professions. 128 patients aged 20-25 with the impacted lower third molar were divided into two groups extracted those teeth under incision A and B shown at the fig.1. And degree of swelling, pain complained, and clinical wound haling on 1,3 and 7 days after extraction of the teeth were observed and analyzed to evaluate which incision is better to extract those teeth. The results were summarized like follows: 1. Degree of swelling after extraction was less observed in extraction undertaken under incision A rather than that in incision B. 2. Patients extracted under incision A less complained pain than those extracted under incision B. 3. Clinical wound healing was better the patients extracted under incision A than those extracted under incision B.
