Objective: The aim of this study was to evaluate cracks on root ends following resection and cavity preparation with a laser and two established techniques.
Background Data: If root canal treatment of a tooth fails, an apicoectomy operation may be indicated. Three millimeters of the root tip is resected and a cavity of similar depth with parallel walls is cut to receive a root-end filling.
The aim of this study was to evaluate the accuracy of the Dentaport ZX apex locator for working length determination during root canal retreatment of mandibular molars. Fifteen extracted mandibular first molars with separate mesial canals and apical foraminae and one distal canal were selected. The mesiobuccal and distal canals were investigated; the length with the file tip at the major diameter was defined as the tooth length (TL).

This study evaluated the effect of HQ on saliva B-cell activating factor (BAFF) levels as well as health related quality of life (QoL) in patients with primary Sjögren's syndrome (pSS).
Materials And Methods: Ten pSS patients who had been treated with HQ for at least 2 years and 15 healthy controls (HC) were included in the study.
Objective: In this study, we aimed to evaluate and compare the dentinal walls of root-end cavities for the presence of cracks after cavity preparation using US retrotips and Er: YAG laser.
Materials And Methods: Fifty single-rooted teeth were prepared by Protaper NiTi rotary system and obturated by lateral condensation. Three milimeters of root-end was resected.
Background: Saliva contains antimicrobial peptides derived from oral epithelium as well as neutrophils in the innate immune response. The aim of this study was to examine the association between salivary human neutrophil peptide (HNP) 1-3 levels originating from neutrophils and oral ulcers in patients with Behçet's disease (BD).
Methods: Ninety-five patients with BD (F/M: 39/56; mean age: 38.
