Objectives. The aim of this study was to investigate the number of roots and root canals in the maxillary second premolar in a group of Jordanian population. Materials and Methods. A total of 217 patients, 100 female (46%) and 117 male (54%), received root canal treatment of maxillary second premolar from January 2012 to January 2014. The mean age of the patients was 32.7, ranging from 18 to 60...

EFFECTS OF RAPID MAXILLARY EXPANSION ON UPPER AIRWAY; A 3 DIMENSIONAL CEPHALOMETRIC ANALYSIS Yoon H. Chang D.D.S. Marquette University, 2011 The purpose of this study was to use cone-beam computed tomography (CBCT) to assess changes in the volume and cross sectional areas of the upper airway in children with maxillary constriction treated by rapid maxillary expansion (RME). The study group cons...

BACKGROUND An impacted tooth is one which fails to reach the occlusal plane even after two-third's of its root completion. Though the etiology is multi-factorial, most common reason is crowding of teeth with lack of space for eruption. Mandibular third molars are the most commonly impacted teeth. Very few studies have been done to assess the prevalence of impacted premolar teeth. MATERIALS AN...

Macrodontia is a rare dental anomaly that refers to teeth that appear larger than normal. Generalised macrodontia can be associated with certain medical conditions and syndromes. This case report presents clinical and radiographic findings of isolated bilateral macrodontia in a 14-year-old child. The patient was referred to the clinic with local crowding of maxillary and mandibular teeth. Radio...

Regenerative endodontic treatment was performed on a mature maxillary premolar diagnosed as chronic pulpitis. The root canals were chemomechanically prepared and placed intracanal medicaments at the first appointment. Then 2 weeks later, a blood clot was created in the canals, over which mineral trioxide aggregate was placed. At 6-month follow-up, cementum-like tissue seemed to be formed in the...

We successfully treated a Class II Division 2 patient with maxillary group distalization using interradicular miniscrews. A woman, aged 28 years 11 months, had a convex profile and an excessive overjet caused by a skeletal Class II jaw-base relationship. After leveling and alignment, titanium miniscrews were obliquely implanted between the maxillary second premolar and first molar. To distalize...
