Multidisciplinary Approach for Full-Mouth Rehabilitation of a Young Adult Patient with Ameloblastoma.

Ameloblastoma is a benign but locally invasive neoplasm of the odontogenic epithelium that tends to grow slowly in the mandible or maxilla. It can be highly destructive to the surrounding dental anatomy and can cause death by progressive spread to nearby vital structures in rare cases. Marginal resection is the most effective method of eliminating the tumor, but treatment can further contribute to oral and dental deformity and malfunction. This clinical report describes the dental rehabilitation of a young adult patient diagnosed with ameloblastoma and underwent preliminary marsupialization, segmental mandibulectomy, and fibula free flap reconstruction, followed by mandibular dental implant placements. Orthodontic and rapid palatal expansion for maxillary arch correction was also performed. The treatment goal of regaining dental function and a satisfactory appearance was accomplished.

Authoritarian-Benevolent Leadership, Moral Disengagement, and Follower Unethical Pro-organizational Behavior: An Investigation of the Effects of Ambidextrous Leadership.

Drawing on the social cognitive theory of moral disengagement, this study examined the influence of the authoritarian-benevolent style of ambidextrous leadership on follower unethical pro-organizational behavior (UPB), mediated via moral disengagement. We tested the hypotheses using a sample of 175 participants at two time points. The results indicated that authoritarian-benevolent leadership affects moral disengagement. In addition, followers in congruent dyads with low authoritarian-benevolent leadership perceived higher levels of moral disengagement than those in congruent dyads with high authoritarian-benevolent leadership. Furthermore, high authoritarian-benevolent leadership had an indirect effect on follower UPB via moral disengagement. Theoretical and practical implications and future research directions are suggested.

Role ambiguity and economic hardship as the moderators of the relation between abusive supervision and job burnout: An Application of uncertainty management theory.

Based on uncertainty management theory (Lind & Van den Bos, 2002; Van den Bos & Lind, 2002), we explored whether uncertainty in the workplace (role ambiguity) as well as off the workplace (economic hardship) moderates the relationship between abusive supervision and subordinates' job burnout. Using survey method, we obtained 458 valid responses from employees in a transportation company in Taiwan. The results of moderated hierarchical regression showed that both role ambiguity and economic hardship induce the positive relationship between abusive supervision and subordinates' job burnout. Abusive supervision related more strongly to job burnout when subordinates perceived higher role ambiguity (higher uncertainty) or higher economic hardship (higher uncertainty). As predicted, high uncertainty increases subordinates' attentions to the injustice from abusive supervision and thus strengthens the negative psychological consequences of abusive supervision, regardless of whether the source of uncertainty corresponds to the source of (in)justice perception.
