Objective: This study aimed to clarify the perceptibility of periapical foreign materials in imaging compared with histopathology. We hypothesized that dentoalveolar imaging is sufficient to detect periapical foreign bodies.

Material And Methods: Radiological and histopathological records of patients diagnosed with periapical granuloma or radicular cyst from 2000 to 2013 were evaluated retrospectively.

Background: Primary sites for the metastasis of oral cancer are the cervical lymph nodes. Although there has been considerable technical advancement in the radiological imaging, capability to recognize all metastatic lymph nodes pre-operatively has remained as a challenge. Thus elective neck dissection (END) has remained as reliable practice to treat cervical lymph nodes.

Objectives: The purpose of this study was to compare magnetic resonance imaging (MRI) maximum tumor diameter and depth of invasion with histopathology in oral tongue squamous cell carcinoma (OTSCC) patients in our Institute. Another objective was to compare recorded nodal status between MRI and histology.

Material And Methods: MRI and pathological records of 45 patients diagnosed with T1-T3 OTSCC were reviewed retrospectively.

Purpose: Associated injuries (AIs) are hypothesized to be frequent in geriatric zygomatico-orbital (ZMO) fractures. The study aim was to determine the relation between ZMO fractures and AIs in geriatric patients compared with younger adult patients.

Patients And Methods: A retrospective case-and-control study was carried out on geriatric patients at least 65 years of age (n = 93) and younger adult patients 20 to 30 years of age (n = 68) diagnosed with pure unilateral ZMO fractures.

This study aims to clarify demographic and clinical aspects of patients with ameloblastoma treated at a single Finnish institute during 1985-2016. Associations between predictor variables (gender and age) and outcome variables (location, tumour type, growth patterns and average tumour size) were sought. A retrospective cohort study was designed and implemented including 34 patients diagnosed with primary ameloblastoma and treated at the Helsinki University Central Hospital.
