The hallmark of neglected Ischemic Priapism is increasing tissue necrosis and hypoxia due to blocked venous outflow caused by unrelieved tissue pressure inside a confined compartment. inside six hours of start, irreversible changes to corporal tissue take place because of RIP, which causes time-dependent alterations inside the corpora cavernosa. While 50% of patients can maintain their erectile function if their priapism is treated within 24 hours, the maintenance of erectile function and the response rate to distal shunt procedures progressively decrease as priapism lengthens. Guidelines2022 from the American Urological Association state that once more conservative methods have failed, a distal penile shunt surgery is usually part of the management of neglected Ischemic Priapism. Distal shunts, such as intracavernosal tunneling, have poor results for protracted ischemic priapism, with just 30% of priapic episodes lasting more than 48 hours successfully treated. Penoscrotal corporal decompression (PSD) is a simple technique in the management of neglected Ischemic Priapismwith fewer complications & less cost with the restoration of erectile function than other techniques. PSD has favorable results in maintaining adequate sexual function as If PSD does not produce a long-lasting new shunt from the corpora cavernosa to the glans or spongiosum, there may be a greater chance of restoring physiological erectile function.

Background: Adhesive tooth-colored restorations are strongly dependent on the substrate surface cleanliness to allow intimate contact between resin cement and dentin surface, so several methods were adopted for the total cleaning of temporary cement residues. This study aimed to assess the effect of mechanical and chemo-mechanical cleaning methods of temporary cement on the immediate shear bond strength of self-adhesive resin cement to dentin surface. Methods: Forty freshly extracted lower first premolars were cut to expose a flat dentin surface. Discs of temporary crown composite resin material were constructed and cemented to the flat dentin surface using resin-based and non-eugenol temporary cement then stored at room temperature in distilled water. Dividing of samples into two groups according to the method of temporary cement cleaning. Group I (n = 20) mechanical cleaning using the rotary instrument, and group II (n = 20) chemo-mechanical cleaning using chlorhexidine-containing scrub. CAD/CAM reinforced Composite discs were bonded to the dentin surface using self-adhesive composite resin cement, then measurement of shear bond strength was done using a universal testing machine. Further analysis of failure mode after debonding was performed by Scanning electron microscope. Results: No statistically significant difference was found between the mean shear bond strength of the two cleaning methods (P-value = 0.636). Regardless of the cleaning method, the group cemented with resin-based temporary cement showed statistically significantly higher mean shear bond strength than non-eugenol temporary cement (P-value = 0.048). Conclusion: Both cleaning methods (mechanical and chemo-mechanical) applied in this study were effective in cleaning temporary cement remnants from the dentin substrate surface with statistically significant differences between results of shear bond strength with significantly higher values recorded with resin-based temporary cement.
