The finite element method (FEM) has established itself as a powerful tool in biomechanics. However, developing a finite element three dimensional mesh for irregular geometry object is still a labor intensive task hence limits the usage of the three dimensional analysis for dental structures. This study presented an automatic procedure to generate the three dimensional finite element mesh of a m...

Aim: The aim of this study was to evaluate the role of a resorbable membrane with a bone graft substitute in the management of a circumferential infrabony defect in a maxillary left first premolar in a patient diagnosed with localised aggressive peri-odontitis. Methodology: A circumferential defect of 5 mm around the maxillary premolar was evident after debridement. The defect was filled up wit...

Ectopic eruption is a concept including those clinical cases in which teeth show abnormal eruption pattern and erupt ectopically, in an incorrect position. This abnormality has been pointed out in the literature for the fi rst permanent molars, mainly the maxillary ones. There is no specifi c etiological factor for this abnormality in the fi rst permanent molar, but different factors are report...

The present study was carried out to observe root canal variations in maxillary and mandibular first premolar teeth in the local population using spiral computed tomography. Sixty, each of well formed maxillary and mandibular first premolar teeth without any carious lesions were used in this study. They were placed in 5% sodium hypochlorite solution for 30 minutes for the removal of organic deb...

CASE REPORT A 37–years old male patient of Indian origin was referred to the Department of Conservative Dentistry and Endodontics for treatment of carious teeth. An intraoral examination revealed an Angle’s Class I molar relation with a well aligned upper and a lower arch. Full complement of permanent teeth was present. Generalized dental fluorosis was seen in teeth of both arches. Though the t...

Introduction: Different treatment approaches are indicated for crown-root fractured teeth. Surgical extrusion is a onestep procedure that implies immediate repositioning of the tooth into its normal position. The aim of this case report was to report the multidisciplinary treatment of a crownroot fractured maxillary premolar. Methods: In this case, a crown-root fractured maxillary premolar was ...

objectives : anterior maxilla, known as the esthetic zone, plays an important role in facial and smile esthetics. this study assessed the frequency of implant treatments in the esthetic zone of patients presenting to dental implant department of tehran university during 2002-2012. materials and methods: this descriptive study was conducted on dental records of patients receiving implant treatme...

The purpose of this study was to determine the effects of the Jones jig appliance on distal movement of maxillary molars and reciprocal effects on premolars and maxillary incisors. Cephalometric radiographs before and after orthodontic treatment of 72 consecutively treated patients, 46 females and 26 males, were measured to define treatment changes attributed to the Jones jig. Comparative measu...

To elucidate the dental pulp-representing area in the human primary somatosensory cortex and the presence of A-beta fibers in dental pulp, we recorded somatosensory-evoked magnetic fields from the cortex in seven healthy persons using magnetoencephalography. Following non-painful electrical stimulation of the right maxillary first premolar dental pulp, short latency (27 ms) cortical responses o...

An integrated experimental and theoretical approach is proposed for the evaluation of stress within a natural tooth during bruxing. A physical model was developed that used strain gauges bonded to the buccal and lingual heights of contour of extracted, intact maxillary premolar teeth for the validation of a two-dimensional finite element model of a natural, intact maxillary premolar tooth. Resu...
