Impacted maxillary permanent canine is the tooth that most commonly fails to erupt after the third molars. It can probably affect the dental arch alignment and form, occlusal function and facial profile as well. In this review, the epidemiology, etiology and influence on surrounding tissue of the impacted maxillary permanent canine were analyzed based on related literatures with the hope of providing references for clinical practice.

#19
Richard Sehnal
The Afrotropical genus Brachylepis Kolbe, 1894 (Scarabaeidae: Melolonthinae: Leucopholini) was established for Coniopholis elephas Gerstaecker, 1867 from Kenya. Subsequently, Brenske (1898) described Brachylepis bennigseni from Tanzania (Pare Mountains), and Lacroix (2009) described B. werneri from Ethiopia (Negele Borana) and synonymised B. bennigseni with B. elephas. Thus, the genus contains only two species. From the closely related Afrotropical leucopholine genera (e.g., Eulepida Kolbe, 1894, Eulepidopsis Burgeon, 1946, Cochliotis Kolbe, 1894) it differs in having nine antennomeres, the terminal maxillary palpomere expanded near midlength, and an incomplete metatibial carina (Lacroix 2009, 2010)...
