The wing base of basal hymenopterans (Insecta) have never been properly described perhaps due to the difficulties of its visualization and understanding the 3D relationships between wing base components. Novel 3D visualization techniques such as microCT and Confocal Laser Scanning Microscopy (CLSM) allow us to provide easily digestible morphological data. The wing base of four basal Hymenoptera and 10 apocritan species have been imaged with CLSM and dissected under a stereomicroscope. The second axillary is composed of two sclerites (on on the dorsal wing membrane and one on the ventral in Macroxyela, Xyela and Athalia whereas it is represented by a single sclerite traversing the wing in other Hymenoptera. Consequences related to this observation as well are drawn and future directions in Hymenoptera wing base studies are provided.

Cuticular Structures

The morphology of the copulatory apparatus and associated cuticular structures in Planorbis planorbis was studied by light microscopy, SEM, TEM and confocal laser scanning microscopy. The significance of these cuticular structures for the taxonomic status of the species and for the systematics of the family Planorbidae in general is discussed.

Following furcal perforation, bacteria may colonize the defect and cause inflammation and periodontal destruction. This study used confocal laser scanning microscopy (CLSM) to evaluate Enterococcus faecalis colonization and proliferation in furcal perforations repaired with different materials. Furcal perforations created in 55 extracted human mandibular molars were repaired using either MTA-Angelus, Endocem, or Biodentine and coronally subjected to E. faecalis suspension for 21 days. The specimens were then stained using a LIVE/DEAD Viability Kit and visualized by CLSM. The minimum and maximum depths of bacterial penetration into the dentinal tubules were 159 and 1790 μM, respectively, with a mean of 713 μM. There were significantly more live than dead bacteria inside the dentinal tubules (p = 0.0023) in all groups, and all three repair materials exhibited a similarly sized stained area (p = 0.083). However, there were significant differences in the numbers of dead bacteria at the circumference of the perforation defect (p = 0.0041), with a significantly higher ratio of live to dead bacteria in the MTA-Angelus group (p = 0.001). Following perforation repair, bacteria may colonize the interface between the repair material and dentin and may penetrate through the dentinal tubules. The type of repair material has a significant effect on the viability of the colonizing bacteria.
