background and aims. wound dehiscence after lower third molar surgery extends the postoperative treatment period and may cause long-standing pain. the aim of this study was to compare wound dehiscence after removal of wisdom teeth in the most prevalent mandibular impaction (mesioangular class ib) by two different soft tissue flap designs. materials and methods. partially-erupted mandibular thir...

In this paper, we consider the projective special linear group $PSL_2(59)$ and construct some 1-designs by applying the Key-Moori method on $PSL_2(59)$. Moreover, we obtain parameters of these designs and their automorphism groups. It is shown that $PSL_2(59)$ and $PSL_2(59):2$ appear as the automorphism group of the constructed designs.
