Thorough understanding of the anatomic and internal morphology of a root canal system is absolutely essential for the success of endodontic treatment. Since permanent maxillary first molars have shown variation in internal anatomy, morphology, this tooth has been reviewed extensively. Presence of two canals in a two-rooted maxillary first molar has rarely been reported in studies describing too...

Abstract Objective The purpose of this study was to evaluate the number roots and canal configuration maxillary first second molars in Qatari population. Materials Methods A total 544 cone-beam computed tomography (CBCT) records patients were included study. CBCT images reviewed by two endodontists. age, sex, bilateral symmetry, root number, according Vertucci tabulated. Results About 97.5% had...

OBJECTIVES To assess the prevalence of both impaction and associated pathosis in a Saudi population in Al-Madinah, Saudi Arabia based on digital panoramic radiographs. METHODS This study was carried out from December 2013 to February 2015. Panoramic radiographs of 359male patients attending the Oral Diagnosis Clinics, Faculty of Dentistry, Taibah University, Al-Madinah, Saudi Arabia were revi...

This report describes the nonsurgical treatment of a patient with skeletal Class II protrusion and severe crowding. A 20-year-old woman presented with the chief complaint of lip protrusion and crowding. To correct the Class II relationship, severe crowding, and lip protrusion, distal movement of the maxillary first molars using indirect miniscrew anchorage and nickel-titanium coil springs, alon...

Context The identification of root canals plays an important role in successful endodontic diagnosis and treatment. An inappropriate identification of canal resulting in incomplete removal of pulp tissue from the root canals is the main reason for the failure of endodontic treatment in molars. Radiographic imaging is an essential investigative tool in successful endodontics. Cone beam computed ...

INTRODUCTION Our objectives were to assess treatment outcomes in Class II Division 1 patients who were treated orthodontically with extraction of the maxillary first permanent molars and to describe the changes in their facial profiles. METHODS This was a prospective, longitudinal, 1-group outcome analysis in a private practice, with outcome evaluation by independent observers at an academic ...

Aim. To determine the root and canal morphology of permanent maxillary first molars in a Sri Lankan population with special emphasis on the presence of a second canal in the mesiobuccal root. Materials and Methods. One hundred and fourteen permanent maxillary first molars were examined. The root numbers of the molars were recorded. Root canal morphology was studied using a clearing technique. T...

AIM Distal movement of maxillary molars is a reasonable but often challenging treatment alternative for patients with a dental Class II occlusion and an increased overjet or anterior crowding. One problem is that most of the conventional noncompliance devices that distally move maxillary molars lead to some anchorage loss. As such, a new appliance was designed that is connected to two coupled m...

A total of 263 ankyloscd primary molars in 107 children aged three to 12 years was studied for four years. Forty-six children remained in the study for eight years. Observation of affected dentitions showed that the condition was likely to recur. Three clinical pa~terns for the condition are described. Typically, maxillary molars became ankylosed earlier and demonstrated more severe in[raocclus...

INTRODUCTION This study aimed to compare the thickness of the mesiobuccal furcal canal walls of first and second maxillary molars. MATERIALS AND METHODS This study was performed on total of 30 first and second extracted molar teeth (15 each). The mesiobuccal roots of each tooth were separated at the cement-enamel junction (CEJ) level and embedded in acrylic resin. The embedded roots were cut ...
