OBJECTIVE Surgical removal of impacted mandibular third molars with primary wound closure may result in postoperative edema, facial swelling, pain, and restriction of mouth opening. The type of closure may be a cause of these complications. The aim of this study was to compare the effects of placement of a surgical tube drain before primary closure with the effects of primary closure alone afte...

Introduction: Impaction of third molars can be associated with a number of sequelae, each requiring a different type of treatment. The purpose of this study was to assess the changes in the position of lower third molars following extraction and non-extraction orthodontic treatments. Methods: Pre- and post-treatment panoramic radiographs of 26 class I malocclusion patients (4 male and 22 female...

BACKGROUND/PURPOSE The objectives of this study were to identify the bilateral distolingual (DL) canals / roots of the mandibular first molars and second mesiobuccal (MB2) canals of the maxillary first molars in the same Turkish individuals using cone-beam computed tomography (CBCT). MATERIALS AND METHODS A total of 150 CBCT images including all mandibular and maxillary first molars were retr...

PURPOSE This study was performed to compare the accuracy of micro-computed tomography (CT) and cone-beam computed tomography (CBCT) in detecting accessory canals in primary molars. MATERIALS AND METHODS Forty-one extracted human primary first and second molars were embedded in wax blocks and scanned using micro-CT and CBCT. After the images were taken, the samples were processed using a clear...

Understanding the morphology of the root canal plays a key role in the success of a root canal therapy. Thus considerations of the anatomic variations, in the process of diagnosis and treatment of the maxillary and mandibular posterior teeth, should be done by the clinicians.1 A thorough examination of pre-operative and postoperative radiagraphs plays a critical role in endodontic success. Vari...

A case of unusual root morphology is presented to demonstrate anatomic variations in mandibular second molars. The most common configuration of mandibular second molar is to have two roots with three root canals; however mandibular molars may have many different combinations. Endodontic therapy was performed in a mandibular second molar with 3 separate roots 2 located mesially and one distally....

background and aims. the knowledge of variations in root canal morphology is critical for a successful endodontic treatment. the purpose of this study was to investigate variations in the root canal system of human mandibular first permanent molars in an iranian population. materials and methods. in this study, 209 mandibular first molar teeth were decalcified, dye-injected, and cleared in orde...

PATIEN'l' J. Z., a white boy 13 years 9 months of age, had a Class II, Division 1 malocclusion. This diagnosis could be determined only in the canine area, since no mandibular molars were present on either the right or the left side. The maxillary arch was normal in width and in protraction. The maxillary right second premolar was blocked out lingually and rotated mesially, and the maxillary le...
