Personality traits of endodontic residents indicate potential for becoming endodontic faculty.

Dental schools across America are challenged by the shortage of qualified faculty to fill vacant positions. This project, conducted through survey methodology, focused on obtaining a basic understanding of the personality types that seek out and maintain positions as full-time endodontic educators and compared those educators with endodontic residents to define similarities and differences that could lead to strategies to recruit those residents into academic endodontic education to assist in alleviating the faculty shortage in dentistry. All full-time endodontic faculty and residents were invited to participate.

Remaining dentin thickness in the apical 4 mm following four cleaning and shaping techniques.

The aim of this study was to determine the remaining dentin thickness (RDT) in the apical 4 mm following four cleaning and shaping techniques. Sixty human adult extracted mandibular incisors and 60 mesial buccal canals of mandibular molars were assigned to five groups of 12 teeth for each tooth type: Step-down stainless steel hand instrumentation, Lightspeed, Profile GT and 0.4 taper, K3 "g pack," control group.
