introduction: there are numerous factors that can lead to tooth discoloration after endodontic treatment, such as penetration of endodontic materials into the dentinal tubules during root canal treatment. the aim of this in vitro study was to compare discoloration induced by tooth colored mineral trioxide aggregate (mta) and calcium-enriched mixture (cem) cement in extracted human teeth. method...

To the Editor: A 9-year-old girl was admitted with surgical-site infection after triple pelvic osteotomy. Superficial wound exudate culture yielded methicillin-resistant Staphylococcus aureus (MRSA). Ultrasound revealed a soft tissue heterogeneous collection with subcutaneous fistulization. She completed 14 days of intravenous vancomycin and gentamicin with clinical and laboratory improvement. ...
