Epidermoid cyst is a rare developmental cyst of the oro-facial region which results from entrapped epidermal elements with an incidence of 6.9-7% and represents less than 0.01% of all oral cavity cysts. PRF, as a physiologic fibrin matrix, serves as a net to stem cells, especially when an accelerated angiogenesis develops in the fibrin membrane. This aspect is of particular interest in the case of wide osseous defects. The Color Power Doppler detects minute areas of blood flow and the velocity of blood flow in healing bone by recording the change in frequency caused by the moving red blood cells. It demonstrates the progressive formation of new vessels in bone during the initial healing period. As the bone remodelling proceeds, there is a decrease in flow signals.

A trapped penile ring is a urological emergency rarely seen. An impacted ring in penis is a real emergency uncommonly faced by a urologist. Emergent removal of the penile ring is indicated to prevent gangrene and damage to the penis. The insertion of these rings for autoerotic purposes is not uncommon. However, this can lead to impacted, stuck articles, rings in the penis. These patients present with symptoms ranging from mild penile pain, swelling to gangrenous changes in the penis. The removal of ring constricting penis is a penile-saving procedure. We describe a patient with a stuck ring in the penis and the technique of removal of the impacted penile ring by a household device plier. In case of emergency, the pliers are a useful tool for removing a strangulating penile ring
