AIM Aim of this study was to compare the volume and the shape of mandibular condyles in a Caucasian young adult population, with different skeletal pattern. MATERIAL AND METHODS 200 Caucasian patients (15-30 years old, 95 male and 105 females) were classified in three groups on the base of ANB angle: skeletal class I (65 patients), skeletal class II (70 patients) and skeletal class III (65 pa...

Methods: The sample consisted of 20 subjects (20 left and 20 right mandibular third molars) who underwent pre-operative radiographic evaluation before extraction of impacted mandibular third molars. On panoramic radiographs, the most common high risk injury signs of inferior alveolar nerve (darkening of roots, interruption of white line, deviation of mandibular canal, narrowing of mandibular ca...

Few studies have attempted to analyse preoperative factors that complicate the surgical removal of impacted mandibular third molars. We studied this problem in two steps. We found that difficulty in extraction is associated with depth (depth is deep occlusal level: level C), ramus relationship/space available (ramus relationship/space available is no space: class 3), width of root (the width of...

AIM To develop a statistical index based on the phase space reconstruction (PSR) of the electrocardiogram (ECG) for the accurate and timely diagnosis of ventricular tachycardia (VT) and ventricular fibrillation (VF). METHODS Thirty-two ECGs with sinus rhythm (SR) and 32 ECGs with VT/VF were analyzed using the PSR technique. Firstly, the method of time delay embedding were employed with the in...

Rhinomanometry provides a means to quantify the nasal airway in terms of its conductive efficiency by use of the inverse or resistance to airflow. In samples of 21 male and 26 female subjects, nasal airway resistance was compared with a number of form measurements and the coefficients of correlation were calculated. Statistical significance was found in some of the relationships with nasal airw...

introduction: the aim of this study was to evaluate the root canal morphology of mandibular first and second molars using cone-beam computed tomography (cbct) in northern iranian population and also to indicate the thinnest area around root canals. methods and materials: we evaluated cbct images of 154 first molars and 147 second molars. by evaluating three axial, sagittal and coronal planes of...

Method: Bilateral mandibular premolars of 6 dogs were extracted, and after 12 weeks each dog received 8 Morse-cone connection implants immediately loaded. Four experimental groups were constituted: subcrestal with interimplant distance of 2mm and 3mm; and equicrestal with interimplant distance of 2 mm and 3 mm. After eight weeks, the animals were euthanized, the retrieved specimens were prepare...

background and aims. current infiltration techniques for achieving anesthesia in dental procedures are not applicable in posterior mandibular region because of its dense cortical bone. the aim of this study was to evaluate the efficacy of a specific infiltration anesthesia in posterior mandibular teeth instead of inferior alveolar nerve block for restorative procedures. materials and methods. c...

BACKGROUND The position and arrangement of teeth as well as the entire scheme of occlusion differs from one individual to the other .The purpose of this study was to examine differences in position and inclination of incisors, overjet, overbite and lower arch crowding in subjects with different depths of curve of Spee and to determine correlations between depth of curve of Spee and these variab...

background and aims. one of the most common reasons for the inferior alveolar nerve block anesthesia failure is the variation in mandibular foramen location. the aim of this study was to assess the location of mandibular foramen in children with mandibular retrognathism in comparison to children with normal skeletal occlusion in the mixed dentition. materials and methods. one hundred and twenty...
