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.

Retrospective clinical and radiologic evaluation of nonsurgical endodontic treatment in human immunodeficiency virus (HIV) infection.

Purpose: This retrospective study evaluated the clinical and radiographic status of nonsurgical endodontic treatment (ET) of anterior and posterior teeth in HIV-seropositive patients.

Methods: ET was analyzed in 26 anterior and 34 posterior teeth from 54 consecutive HIV patients (gender ratio 3 Male : 1 Female, mean age 40.2 years, mean CD4 240, CD4<500 in 88%, 12 with AIDS) over a six year period with a minimum of six months follow-up.

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.
