Detection of the Accessory Mental Foramina on Human Mandibles Using Cone-beam Computed Tomography: A Systematic Review and Meta-analysis.

Introduction: This study aimed to perform a systematic review and meta-analysis on accessory mental foramen (AMF) research using cone-beam computed tomographic (CBCT) imaging.

Methods: A systematic review was performed in PubMed, Embase, Thomas Reuter's Web of Science, Scopus, and ScienceDirect databases according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis statement. Articles focusing on AMF prevalence and location using CBCT imaging were selected without language restrictions.

Root resorption in chronic periodontitis: a morphometrical study.

Background: It has been previously observed that teeth with severe chronic periodontitis experience more transient external root resorptions than teeth with less severe disease.

Methods: Sixty-six teeth diagnosed with different levels of chronic periodontitis in 48 patients were observed with a light microscope. Main characteristics of teeth with root resorptions, as well as percentages of area and volume resorbed on each radicular third of the teeth, were determined.
