OBJECTIVE To evaluate the efficiency of the Frog appliance (FA) alone or in combination with headgear for distalizing the maxillary molars. METHODS Fifty patients (25 males and 25 females) aged 12.6 - 16.7 years who received treatment for Class II malocclusion at the Orthodontic Clinic of Al-Baath University were selected for this study and randomly divided into 2 equal groups. Maxillary mola...

introduction: coronal anatomic variations in permanent maxillary molars are unusual; conversely variations involving the number of root canals or number of roots are more common. methods and materials: this case report presents a successful nonsurgical endodontic therapy of left maxillary first molar with three roots and seven root canals. this unusual morphology was diagnosed using a dental op...

INTRODUCTION Our aim was to investigate 8 years of vertical changes of the gingival margin and tooth displacement of maxillary molars and incisors in adolescents and adults. METHODS Twenty-five adolescents and 10 adults were included in this study, with dental casts taken 2 and 10 years after orthodontic treatment. The gingival contour of the teeth was traced digitally using calibrated photog...

Reviewing the literatures, the most frequently impacted tooth was mandibular third molar, followed by the maxillary third molars, the maxillary canines and the mandibular premolars. The current case report aimed to present a rare inverted and impacted maxillary third molar incidentally detected in a patient of mandibular unicystic ameloblastoma on panoramic radiography, highlighting the importa...

Aims and objectives: Identification of an individual is based on characteristics like gender, age and racial background unique to that individual. Out of all the parameters determination of gender falls first in line. Teeth can be used to determine gender dimorphism as they are the hardest structures and can withstand any adverse conditions. The present study aims to determine gender of an indi...

introduction: the aim of the present study was to compare the efficacy of 2% lidocaine to 4% articaine in buccal infiltration of maxillary first molars with irreversible pulpitis. moreover, the effect of root length on success of anesthesia irrespective of the type of anesthetic agent was assessed. methods and materials: fifty patients suffering from painful maxillary first molars with irrevers...

the most difficult maxillary teeth for endodontic treatment are the maxillary first molars (mfm) due to their complex root canal anatomy. the presence of two roots and c-shaped canals in mfms has been reported in rare cases. the present case reports root canal treatment of mfm with two roots, where the palatal and buccal roots were joined together in a c-shaped configuration .

OBJECTIVE To evaluate the reproducibility of four parameters for quantitatively assessing maxillary molar furcation involvement (FI) by cone beam computed tomography (CBCT). METHODS Thirty-nine sites with degree II FI, classified by probing of 21 maxillary molars, were investigated. Degrees of FI in these sites were assessed based on CBCT data. In these samples, four parameters for quantitati...

OBJECTIVES The purpose of this study was to investigate the incidence of root fusion and C-shaped root canals in maxillary molars, and to classify the types of C-shaped canal by analyzing cone-beam computed tomography (CBCT) in a Korean population. MATERIALS AND METHODS Digitized CBCT images from 911 subjects were obtained in Chosun University Dental Hospital between February 2010 and July 20...

BACKGROUND This study cephalometrically compared the dentoskeletal and soft tissue changes consequent to one and three-premolar extraction protocols of class II subdivision malocclusion treatment. METHODS A sample of 126 lateral cephalometric radiographs from 63 patients was selected and divided into two groups. Group 1 consisted of 31 type 1 class II subdivision malocclusion patients treated...
