AIM To describe the successful non-surgical endodontic management of a permanent maxillary lateral incisor tooth with four root canals. SUMMARY Aberrant morphology of root canals can occur in any tooth, including maxillary lateral incisors. In the presented case, clinical examination and radiographs clearly depicted the presence of four root canals in a right maxillary lateral incisor. The di...

A healthy 13-year-old female was found to have no roots on the maxillary left second premolar and permanent first and second molars. Her history included chronic sinus infections treated with maxillary sinus curettage at approximately 4 years of age. The infection, or more likely the trauma associated with the surgery, may have caused agenesis of the roots. Other causes of rootless teeth such a...

BACKGROUND The management of bisphosphonate related necrosis of the jaw has become clinical routine. While approximately two thirds of the lesions are in the mandible, one third is located in the maxilla. In 40-50 % of maxillary necrosis the maxillary sinus is involved, leading to maxillary sinusitis and oro-antral communications. METHODS This retrospective single center study includes all pa...

Ampullary neoplasms are one of the causes of obstructive jaundice. Endoscopic retrograde cholangiopancreatography (ERCP) is useful procedure for diagnosing and tissue sampling of ampullary neoplasms. Ampullectomy by resecting entire ampulla provides whole lesion for pathologic evaluation and also is appropriate for real pathologic staging for further management decision but ampullectomy conside...

899 Abstract The maxillary stylets and maxillary palps of three species of mosquitoes belonging to genus Anopheles, viz., Anopheles culicifacies Giles, Anopheles fluviatilis James Anopheles subpictus Grassi have been studied using scanning electron microscope. The studies reveal the presence of lateral teeth and absence of mesial teeth on the maxillary stylets. The number, shape and size of lat...

Maxillary antrolith is a mineralized mass found very rarely in the maxillary sinus formed by exogenous or endogenous origin [1,2]. These mineralized bodies have been variously described as rhinoliths, antral rhinoliths, antral stones, antral calculi, antroliths, sinoliths, maxillary sinus stones and antrorhinoliths. The maxillary sinus is covered by ciliated pseudostratified columnar epithelium...

The grass carp (Ctenopharyngodon idella) is a herbivorous, freshwater fish species of the family Cyprinidae, and the only species of the genus Ctenopharyngodon. Neoplasms in fishes are generally less aggressive than neoplasms in mammals and are most commonly discrete, focal and benign neoplasms. A 3-year-old grass carp with a big mass on the vertebrae was referred to the clinic...

Treatment of Class II malocclusions, without extractions, frequently requires distalization of maxillary molars into a Class I relationship by means of extra-oral or intraoral forces. Several methods and devices can be used to distalize maxillary molars and to correct Class II malocclusions. The most conventional method for distalizing the maxillary molars involves use of cervical headgear but ...

The purpose of this study was to expose a new classification odontogenic maxillary cysts post-dental implant and asses functional surgical treatment with fewer complication, which not only insured normal maxillary sinus cilia restoration and bony integrity but also did little damage to maxillary sinus natural ostium. The maxillofacial region is affected by a greater number of cysts. Chronic max...
