We characterized and compared taxonomic features of two species of tree crickets Oecanthus in tobacco plantation and adjacent native trees and bushes at Southern Brazil. The marked differences between species included Oecanthus n. sp. with palegreen body, pale-yellow head, greenish-white eyes, file teeth number 32.8±1.2 (31–34, n = 6) and hindwings caudate. Oecanthus lineolatus is slightly dark...

There are several restorative alternatives for replacing a missing anterior tooth. The single implant-supported crown is among the best restorative options under certain biological and biomechanical condition like sufficient bone quantity, condition and morphology of the periodontium, integrity of natural and restored teeth. The long-term success of an implant supported crown depends upon the h...

Tooth fusion is a developmental anomaly characterized by the union between the dentin and/or enamel of at least two separately developing teeth. The fusion of posterior teeth is an uncommon occurrence. In this article, we report a rare case of unilateral fusion of a mandibular second molar with a paramolar. Carious exposure mandated endodontic treatment. The unusual morphology and complex root ...

The variability of root canal system morphology of multirooted teeth represents a continuous challenge to endodontic diagnosis and therapeutics. This report extends the range of known possible anatomical variations to include teeth with lesser number of root and root canals. Variations of root canal systems need not always be in the form of extra canals. Clinicians should be aware that there is...

The maxillary first molar usually has single palatal root. Incidence rate of maxillary first molar with two palatal roots is especially rare. We reported a case of young maxillary first molar with two palatal roots in this article. Anatomic characteristic of permanent maxillary molar is generally described as a group of teeth with three roots, one palatal and two buccalbut the root canal system...

The ability to perform hygroscopic movements has evolved in many plant lineages and relates to a multitude of different functions such as seed burial, flower protection or regulation of diaspore release. In most mosses, spore release is controlled by hygroscopic movements of the peristome teeth and also of the spore capsule. Our study presents, for the first time, temporally and spatially well-...
