Emergency care provided in a Greek dental school and analysis of the patients' demographic characteristics: a prospective study.

Objectives: The aim of this study was to evaluate the incidence of pain of endodontic origin and its relationship with socio-economic and demographic factors among patients seeking unscheduled urgent dental care.

Methods: Patients attending the Emergency Clinic of Athens Dental School, Greece, between November 2011 and June 2012, were evaluated to determine their socio-economic profile, dental problem and treatment required. The facility operated from Monday to Friday, from 8.

Device and materials for in vitro evaluation of forces developed to teeth and periodontal structures during dental practices.

This study aimed at providing a gauge device (Ekontak et al Gauge K-Device) in order to analyze the forces applied to teeth and periodontal tissues during dental practices in vitro. This force gauge device can be used in the investigation of the possible defect generation to tooth structures when overloaded forces are applied during dental procedures in vitro. Ekontak et al Gauge K-Device consists of three units: the specimen's holder, a high-performance digital force gauge, and the support frame.

Prevalence of impacted teeth in a Greek population.

Aim: Τo determine the prevalence of impacted teeth in an adult Greek population, according to type, sex, and age.

Methods: The major source of data for this study was the orthopantomographic films and the physical examinations of 425 patients (202 males and 223 females) with impacted teeth. The elements that were examined and processed were relevant to the age, sex, total number of impacted teeth, and the type and frequency of impaction of each tooth.

Comparison of isthmus detection methods in the apical third of mesial roots of maxillary and mandibular first molars: macroscopic observation versus operating microscope.

The aims of this study were to assess the presence and the frequency of isthmuses in the mesial roots of the maxillary and mandibular first molars (at two resection levels from the apex), and to compare the findings obtained by macroscopic observation (MO) and operating microscope (OM). Forty maxillary and 40 mandibular mesial roots were observed at 3 and 5 mm from the apex initially macroscopically and then with the use of an OM. The presence of an isthmus and the number of root canals detected were recorded.
