Prevalence of Middle Mesial Canal in Mandibular First Permanent Molars in a Persian Population: An In Vivo Cone-Beam Computed Tomography Study.

Objectives: This study aimed to identify the prevalence of the middle mesial canal (MMC) in mandibular first permanent molars in a Persian subpopulation sample using cone-beam computed tomography (CBCT). The secondary aim was to correlate the incidence of MMC with variables such as gender, age, and the presence of an additional distal canal.

Materials And Method: A total of 390 mandibular first molars from 314 CBCT images were retrospectively evaluated.

Introducing a new auto edge detection technique capable of revealing cervical root resorption in CBCT scans with pronounced metallic artifacts.

Cervical resorption is a serious threat to the longevity of the teeth. In this study, the Canny edge-detection algorithm was applied on CBCT images to compare the accuracy of original and Canny views for diagnosing cervical resorption in endodontically treated teeth. Intracanal metallic posts were inserted in 60 extracted teeth being randomly divided into three groups: control, 0.

Evaluation of 940-nm diode laser effectiveness on pocket depth, clinical attachment level, and bleeding on probing in chronic periodontitis: A randomized clinical single-masked split-mouth study.

Background: Diode lasers can be used in the treatment of periodontal diseases as they have an anti-bactericidal effect, and regulate oral tissue inflammatory responses. This study aimed to evaluate the adjunctive effects of Diode 940 nm laser on mechanical periodontal debridement.

Materials And Methods: In this split-mouth single-blind randomized clinical trial, 12 patients were selected.

The effect of preheating of composite resin on its color stability after immersion in tea and coffee solutions: An study.

Background: One of the concerns in using composite resins is color change. The aim of this study was to investigate the effect of preheating on color stability of composite resins when immersed in coffee and tea.

Material And Methods: This experimental study included 60 composite disks.
