High cones are known from species with long mouthparts, and lower cones from those with short mouthparts. In some species (e.g. Rhipicephalus spp.) which produce less‐extensive lateral flanges on the skin surface, internal flanges of secondary cement can be found instead (Moorhouse, 1969). Cement aggregations on the skin allow ticks with ...

Increased depths resulted in reduced PBS values for all cementation protocols evaluated (P<.001). Conclusions: Regardless the cementation system used, the lowest PBS values were at the apical region of resin relined glass fiber posts bonded to root dentin. Furthermore, the highest PBS is observed at the cervical portion of root dentin.
