A new species of hymenosomatid crab of the genus Elamena H. Milne Edwards, 1837, is described from the island of Samal, in the Davao Gulf, Mindanao, southern Philippines. Elamena samalensis sp. nov. belongs to the Elamena truncata species-group and is most similar to E. simplidenta Ng & Chuang, 1996, in the general form of the carapace and in the presence of only one subdistal tooth on the ambu...

OBJECTIVE To determine the percent gutta-percha-filled area in the apical third of root canals after filling with 2 different root filling techniques. MATERIALS AND METHODS Thirty extracted human lower premolars were instrumented with ProTaper rotary files (Dentsply Maillefer) and then randomly divided into 2 groups of 15 teeth each. The first group was filled using the single-cone technique ...

OBJECTIVES The aim of this in vivo study was to assess the accuracy of 2 third-generation electronic apex locators (EALs), Propex II (Dentsply Maillefer) and Root ZX II (J. Morita), and radiographic technique for locating the major foramen (MF). MATERIALS AND METHODS Thirty-two premolars with single canals that required extraction were included. Following anesthesia, access, and initial canal...

The amounts of apical enlargement have been a controversial issue for a long time. The enlargement of the apical part of the canal may severely impact the endodontic prognosis. Enlargement of the apical portion to a larger size may negatively affect the ability to control the filling material during root canal obturation. In addition, an open-apex increases the risk for overfilling which has be...

Introduction: Complicated crown fractures involve enamel, dentin, and pulp and occur in 0.9 to l3% of all dental injuries. If left untreated, will always result in pulp necrosis but, if it handled correctly, prognosis of the pulp following a traumatic crown fracture can be favorable.

The association of internal root resorption (IRR) with dens invaginatus is an extremely rare finding, and its incidence may be underestimated, adding to the difficulty endodontic treatment. A 9-year-old boy was admitted complaints swelling pain. Radiological examination revealed closed apex Oehlers type II severe IRR, as well apical third two lateral perforation lesion. Calcium hydroxide applie...

ABSTRACT Partial pulpotomy is a treatment method used to reach healthy pulp tissue by removal of the inflamed in 1-3 mm depth from caries exposed teeth. Pulpal bleeding should be controlled using bactericidal agents, such as sodium hypochlorite or chlorhexidine, and then covered with biocompatible material, MTA. MTA placed on area surrounding dentate thickness at least 1.5 resin modified glass ...
