objectives: to compare the thickness of the lateral wall of the maxillary sinus in individuals with and without teeth to determine if extraction of the teeth can lead to a significant reduction in the thickness of the maxillary sinus lateral wall or not. patients and methods: in a retrospective study on fifty patients with an edentulous space, the thickness of the lateral wall of the maxillary ...

objectives: this study aimed to evaluate the location and characteristics of mental foramen, anterior loop and mandibular incisive canal using cone beam computed tomography (cbct). materials and methods: this retrospective cross-sectional study evaluated 200 mandibular cbct scans for the location of mental foramen, anterior loop prevalence and mandibular incisive canal visibility, its mean leng...

introduction: vertical root fracture (vrf) is a common failure in endodontically treated teeth. due to vrf’s poor prognosis, a reliable and valid detection method is critical for treatment planning. conventional and digital radiographs are limited in vrf detection. recently, cone beam ct (cbct) system has been introduced. this study aimed to compare the diagnostic accuracy of these three imagin...

central granular cell odontogenic tumor) cgcot) of the jaw is an exceedingly rare benign odontogenic neoplasm with 35 reported cases in the literature. among these, very few studies have focused on the cone-beam ct features of cgcot. here, we report a case of an asymptomatic cgcot in a 16-year-old girl and focus on the cone-beam ct features. only 36 cases of this lesion, including this one, hav...

this case report presents an eight-year-old girl having periauricular swelling and severe pain during mouth opening on the right-side temporomandibular joint (tmj). cbct showed extensive destruction of the base of the skull and the roof of the glenoid fossa on the right side. the findings based on ct and mri images with and without contrast are discussed herein. this report highlights a skull b...

objectives: precise radiographic assessment of the nasopalatine canal is required to prevent implant failure. the purpose of the current study was to determine the three dimensional (3d) morphology, as well as the dimensions of the nasopalatine canal using cone beam computed tomography (cbct). materials and methods: in this descriptive cross-sectional study, maxillary cbct images from 300 patie...

conclusions: detailed information about root fractures may be obtained using cbct. results: according to the fracture types and fracture presence, there was an overall statistically significant agreement between the key and readings. kappa values for intra observer agreement ranged between 0.705 and 0.804 indicating that each observer gave acceptable ratings for the type and presence of fractur...

introdouction: cone-beam computed tomography (cbct) scanning is a technological innovation developed in recent years with potential use in oral surgery and many other dental procedures. the aim of this study is to determine the maxillary sinus mucosal thickening in the maxillary premolar-molar area using the cbct technique. materials and methods: in this retrospective study, a total of 105 case...
