BACKGROUND The variation in mandibular molars' anatomy is not as rare as it might appear to be. Depending on the location of the additional root found in a mandibular molar, it may be referred to as either radix entomolaris (RE) or radix paramolaris (RP). The aim of the study was to present radiographic appearance of RE and RP and indicate the clinical implications of its presence. MATERIALS ...

PURPOSE The aim of this study was to systematically review the evidence for periapical implant lesion, which makes a patient more susceptible to the periapical lesion, frequency, symptoms, signs (including radiological findings) and possible treatment options. MATERIAL AND METHODS A systematic literature review and analysis of publications included in PubMed, Embase and Cochrane; articles pub...

The aim of this study was to accomplish quantitative measurement of tissue levels of collagenases (MMP-1, 8 and 13) in chronic inflamed tissues (pulp and periapical lesions), as well as to determine the dependence between collagenase level and the degree of tissue destruction of examined material. Chronic periapical tissues were collected by periapical surgery from 50 teeth with clinically and ...

Purpose: To determine the diagnostic ability of Cone Beam Computed Tomography (CBCT) to detect and localize apical pathoses as compared to two-dimensional conventional direct digital intraoral radiographs (DDR), in order to accurately determine the location and extent of these lesionsto improve treatment outcomes. Methods: Previously obtained CBCT and DDR data from 45 patients with a diagnosis ...

Purpose: To evaluate the ability of BiodentineTM as a retrograde root-end filling in conjunction with a well-documented periapical surgery protocol in a clinical case series study. Material and Methods: Thirteen teeth in 13 patients referred for periapical surgery were included in the study. Teeth with obvious signs of root-fracture or apical-marginal communications were excluded from the study...

Periradicular surgery is often used as a last resort to save an endodontically treated tooth with a persistent periapical lesion. The introduction of surgical microscopes, ultrasonics, and compatible root-end filling materials has made periradicular surgery a much more predictable treatment. The advantages of modern periradicular surgery include easier identification of root apices, smaller ost...

Many endodontists avoid surgical procedures in proximity to the mental foramen. Although a healthy respect for regional anatomy is important, this should not be at the expense of failing to offer the most appropriate endodontic care. When correct preoperative diagnostic and surgical techniques are used, serious negative sequelae are rarely encountered. Three simple steps used during presurgical...

To be able to determine if endodontic treatment of apical pathosis is successful or not, healing of lesions is followed up by radiographic imaging. This can be done by observing changes in apical radiolucencies. Recently, cone beam computed tomography (CBCT) has been introduced as a method of gaining an unabridged view of dental anatomy, thus eliminating some of the most prevalent problems, suc...

Among a variety of biomaterials that have been reported to be ideal for dental repair, calcium hydroxide has been shown to have excellent long-term biocompatibility in the pulp and periapical areas. Here we report an alternative method employing calcium hydroxide for periapical surgery in a patient who developed internal apical resorption after traumatic injury, which negatively affected the qu...
