An HIV infected hemophilia patient with huge inflammatory pseudotumor was in severe ill condition. The operation of right hip joint amputation was performed on the patient with perioperative infusion of coagulation factor VIII and highly active antiretroviral therapy (HAART). The pathological found that Inflammatory cell infiltration, formation of folliculus lymphaticus, muscular fiber breakage...

Despite the progress made in the field of pulp biology, the technique and philosophy of direct vital pulp capping remains a controversial subject. Clinicians are well aware of the immediate and long-term success rates after root canal therapy, but are less certain of the success of vital pulp capping. Researchers have demonstrated that exposed pulps will heal and form reparative dentin. It is r...

Revascularization of immature teeth with necrotic pulps traditionally involves the use of triple antibiotic paste, which may sometimes lead to undesirable complications. The objective of this study was to assess tissue repair in immature dog teeth with apical periodontitis subjected to revascularization, comparing two different pastes used for root canal disinfection. Apical periodontitis was i...

vital pulp therapy (vpt) of permanent mature teeth is continuously ascertaining to be a more reliable endodontic treatment. the purpose of this case report was to describe successful vpt of a mature mandibular left first molar with concurrent hyperplastic pulpitis, internal root resorption and periradicular periodontitis in a 35-year-old male patient. after complete caries removal and access ca...

in this report we describe our encounter of a case of hand trauma referred to our center presenting with incomplete left thumb amputation at metacarpal level with extensor pollicis longus (epl) and flexor pollicis longus (fpl) tendon avulsion from the tenomuscular junction. after metacarpal bone fixation the ulnar digital artery was anastomosed and the digital nerves were coapted. transfer of e...

Optimal development of root architecture is vital to the structure and nutrient absorption capabilities of any plant. We recently demonstrated that AtCLE26 regulates A. thaliana root architecture development, possibly by altering auxin distribution to the root apical meristem via inhibition of protophloem development. In addition, we showed that AtCLE26 application is able to induce a root arch...

Traditionally, when a root-originated fracture (ROF) was diagnosed in an endodontically treated tooth, the tooth was scheduled for extraction. However, modern endodontics offers new treatment options to manage and maintain certain ROF teeth. The decision of whether to extract a ROF tooth and substitute it with a dental implant, or to implement a more conservative management approach by attempti...
