An efficient palladium-catalyzed tandem approach for the synthesis of highly functionalized tetrahydroquinazolines 4a–q, and 5a–f by the reaction of o-haloanilines 1a–g with acrylates 2a–d and isothiocyanates 3aa–3ah/isocyanates 3ba–3bfvia Heck-conjoined amidation/thioamidation and concomitant chemoselective Michael-addition is described. A competitive experiment showed that isothiocyanates wer...

This case report describes an external apical root resorption resulted from the unusual root morphology of the neighbouring tooth. A 28-year-old female was referred to the department of endodontics with a complaint of intense pain in her maxillary second premolar tooth. The clinical and radiographical evaluation revealed an external apical resorption in the mesial root of the maxillary first mo...

Introduction: Congenital missing of maxillary lateral incisors and mandibular second premolars are one of the most common developmental dental anomalies that can affect patient’s function and aesthetics. The aim of this study was to determine the prevalence and pattern of congenital missing of lateral maxillary teeth and second mandibular premolars in patients referred to the Dental Faculty of ...

AIM The purpose of this case report is to describe a nonsurgical endodontic treatment of a mandibular left second premolar with two separate roots and three distinct root canals. BACKGROUND In endodontics, the possible existence of extra canals must be considered before endodontic treatment is instituted. A wide morphological variation of the root canal system is known to exist. CASE DESCRI...

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...
