OBJECTIVES: To determine the number and configuration of canals in permanent maxillary premolars using Cone Beam Computed Tomography (CBCT) relationship between count patient gender northwest region Pakistan. METHODS: This cross-sectional observational study was conducted at Khyber College Dentistry (KCD) Peshawar, Data collected from July 1st to 30th December 2020, 133 patient’s CBCT scans wit...

Implant placement becomes complicated when the height and width of the bone is compromised especially in the posterior maxillary region due to the presence of sinus. This case report presents the rehabilitation of the left maxillary premolar region by using indirect sinus lift and ridge splitting followed by immediate implant placement where the bone height and bone width was compromised. It he...

Identifying and accessing all pulp canals is particularly challenging in the endodontic treatment of teeth with atypical canal configurations. This report describes the nonsurgical endodontic treatment of a maxillary first premolar with three root canals. The prevalence of this unusual morphology is reviewed and suggestions are offered to help dentists identify and treat such teeth. This case r...

PURPOSE Although intracoronal radiolucencies in radiographs of unerupted teeth have been reported for several decades, the prevalence of this condition remains unknown. This study determined the prevalence and associated dental conditions of permanent teeth showing pre-eruptive dentin radiolucencies in bite-wing radiographs of school children attending two school dental therapy training centers...

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...

Tooth morphometry is known to be influenced by cultural, environmental and racial factors. Tooth size standards can be used in age and sex determination. One hundred models (50 males & 50 females) of normal occlusion were evaluated and significant correlations (p<0.001) were found to exist between the combined maxillary incisor widths and the maxillary intermolar and interpremolar arch widths. ...

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...

Maxillary canine premolar transposition is the most frequently reported transposition type, which many orthodontists face. Although correcting the transposed tooth order is not advised after the eruption of the permanent tooth, several articles published in the last decade demonstrated nonextraction treatment of transposition using fixed mechanics. This article describes the nonextraction treat...

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...
