RESUMEN
This article describes a technique for duplicating occlusal surface anatomy using the Biteperf device. Duplication requires an intact occlusal enamel surface and is only indicated when caries lesions are hidden. The occlusal matrix technique allows for preservation of all anatomic details. When the last layer of composite has been placed, the occlusal matrix is forced into the uncured composite to replicate the original occlusal surface, instead of performing manual curing and shaping as in the standard approach. It is technically possible to achieve this effect with any material that is able to copy anatomic details. The main benefits of the occlusal matrix technique, more precisely the Biteperf, are the technical ease of use due to its simplicity and its high accuracy in reconstructing occlusal morphology.

This article presents a clinical case in which the diagnosis and treatment of a lateral canal was instrumental in the successful completion of endodontic therapy. Endodontic treatment was performed by crown-down shaping and copious irrigation (using 2.5% sodium hypochlorite associated with 17% ethylenediaminetetracetic acid (EDTA)). After 10 months, there were no clinical symptoms of inflammation and radiographs showed periradicular healing.

INTRODUCTION: To determine the morphologic shape and position of the root apex and the major foramen in maxillary and mandibular teeth. METHODS: A total of 845 maxillary and mandibular human teeth root specimens were evaluated. Each root specimen was measured at each root apex by using a calibrated microscope at a magnification of 20x. The anatomic parameters evaluated included the position of the root apex and the major foramen (in the center, buccal, lingual, mesial, or distal) and shapes of peripheral contours of the major foramen (rounded, oval, asymmetric, and semilunar) and root apex (rounded, flat, beveled, and elliptical). All data were summarized, and means, frequencies, and percentages were calculated for each group of specimens (incisors, canines, premolars, and molars). RESULTS: The most frequent root apex morphology in maxillary and mandibular teeth was the round shape (35.1%). The most frequent shape of the apical foramen was round (52.9%) or oval (25.2%). The major location of both the root apex (39.7%) and the major foramen (58.4%) was in the center of the root. CONCLUSION: The most frequent root apex morphology and apical foramen in the maxillary and mandibular teeth was the round followed by the oval shape. The most prevalent location of the root apex and the major foramen was in the center followed by the distal position.
