The Pacesetter Style Of Leadership, Michelle C. Dziurgot Dds

The Journal of the Michigan Dental Association

This editorial explores the pacesetter leadership style, likening it to a marathon "rabbit" setting a fast pace. Pacesetters, exemplified by figures like Jack Welch and James Cameron, set ambitious goals, driving themselves and their teams relentlessly. While effective in achieving short-term goals and maximizing team potential, drawbacks include employee stress, lack of feedback, and a "rat race" atmosphere. The author, a self-identified pacesetter with a compassionate approach, emphasizes the importance of balancing high standards with employee well-being for sustained success.

Unique Root Anatomy Of Mandibular Second Premolars: Clinical Strategies For Effective Disinfection And Preservation Of Dentine Structure In Root Canal Treatment-A Case Report, Ji Wook Jeong, Erika Silguero Gonzalez, Scott R Makins, Timothy Kirkpatrick

Faculty, Staff and Student Publications

It is difficult to predict the outcomes of non-surgical root canal treatment (NSRCT) for mandibular second premolars with multiple root canals. In these teeth, the complicated anatomy with fin(s), or a C-shape, and possible secondary canal(s) varies unpredictably. The morphology of the root canals provides shelters for bacteria to remain, regrow, and form biofilms despite the endodontic treatment. Moreover, the prevalence of mandibular second premolars with multiple canals is extremely infrequent. Therefore, the clinical management of NSRCT in such cases is not sufficiently reported. This case report introduces two cases of NSRCT for mandibular second premolars with a radicular groove …
