Prevalence of Periapical Rarefying Osteitis in Patients with Rheumatoid Arthritis.

Introduction: The effect of rheumatoid arthritis (RA) on the healing and pathophyisiology of apical periodontitis is unknown because there is no study in the literature evaluating the association of RA with the prevalence of periapical rarefying osteitis (PAR) and endodontic treatment. Therefore, the goal of this cross-sectional study was to evaluate the prevalence of PAR and root canal treatment in RA patients when compared with controlled individuals.

Methods: Full-mouth radiographs of 131 individuals with RA were examined and compared with 131 controls that were sex and age matched exactly with the diseased group.

Clinical and Patient-centered Outcomes of Nonsurgical Root Canal Retreatment in First Molars Using Contemporary Techniques.

Introduction: There have been many recent technical advances in modern endodontics that have the potential to affect treatment outcomes. Reports on treatment outcomes using contemporary techniques are relatively scarce, especially in the field of nonsurgical retreatment. The purpose of this study was to determine the success of nonsurgical root canal retreatment in molars using contemporary endodontic techniques.

The endodontic diagnostic puzzle.

Endodontic diagnosis is the cornerstone of endodontic treatment. Endodontic diagnosis can be likened to a puzzle, where the pieces must be gathered and pieced together before a clinician can see the complete picture. This article discusses how to collect the pieces and fit them together to see the pulpal and periapical diagnosis emerge.
