Tendon's natural healing potential is extremely low and inefficient, with significant dysfunction and disability due to hypocellularity and hypovascularity of tendon tissues. The application of stem cells can aid in significantly enhanced repair of tendon rupture; therefore, the main aim of this study is to assess the potential of using periodontal ligament cells (PDL), usually obtained from patients undergoing orthodontic treatment, as a novel cell source for cell-based therapy for tendon injuries in a clinically relevant rat full-size Achilles tendon defect...

Large cohort studies on whether any association existed between urological interventions for urolithiasis and the development of CKD are lacking. From claims data of the National Health Insurance (NHI) program of Taiwan, we identified 54,433 patients newly diagnosed with urolithiasis during 1998-2010. For each case, four individuals without urolithiasis were randomly selected and frequency matched by age, sex, and diagnosis year. Both groups were followed up until the end of 2010. Incident CKD events were identified by the International Classification of Diseases, Ninth Revision (ICD-9) code in the NHI registration database...

BACKGROUND: When primary root canal therapy fails, periapical lesions can be retreated with or without surgery. Root canal retreatment is a non-surgical procedure that involves removal of root canal filling materials from the tooth, followed by cleaning, shaping and obturating of the canals. Root-end resection is a surgical procedure that involves exposure of the periapical lesion through an osteotomy, surgical removal of the lesion, removal of part of the root-end tip, disinfection and, commonly, retrograde sealing or filling of the apical portion of the remaining root canal...

This clinical report illustrates a multidisciplinary approach for the rehabilitation of a young adult patient affected by a bilateral edentulous space and an anterior deep bite. The patient required orthodontics and surgical corticotomy and implantology (both performed with a piezo device). A multidisciplinary planning approach, including orthodontics, oral and periodontic surgery, and restorative dentistry, has an important role in the final outcome of treatment. In fact a dental class I occlusion has been established only on the right side...

Plasmin is a proteolytic enzyme that is crucial in fibrinolysis. In oral tissues, the plasminogen system plays an essential role in physiological and pathological processes, which in addition to fibrinolysis include degradation of extracellular matrix, inflammation, immune response, angiogenesis, tissue remodeling, cell migration, and wound healing. Oral tissues reveal a change in the plasminogen system during pathological processes such as periodontitis, peri-implantitis, or pulpitis, as well as in response to mechanical load...

Recession on the lingual aspect of mandibular incisors may occur in patients with history of tongue piercing and other factitious traumatic habits. Treatment of these areas is challenging due to the site-specific anatomical features of the region. This case report presents a novel approach for a specific type of mandibular lingual defect caused by tongue piercing. A nonresorbable titanium-reinforced barrier membrane combined with an allograft and enamel matrix derivatives was used to promote regeneration of periodontal attachment...

BACKGROUND: Different materials have been instigated for renewal of lost supporting periodontal structures and tested for furcation defects treatment. Platelet-rich fibrin (PRF) is a pool of growth promoting factors and cytokines which promotes bone regeneration and maturation of soft tissue. Alendronate (ALN), an influential member of bisphosphonate group is known to enhance osteoblastogenesis and inhibits osteoclastic bone resorption, thus promoting tissue regeneration. This randomized trial was done to assess the effectiveness of PRF and 1% ALN gel combination in mandibular degree II furcation defects treatment in comparison to PRF and access therapy alone...

Research into regenerative dentistry has contributed momentum to the field of molecular biology. Periapical surgery aims at removing periapical pathology to achieve complete wound healing and regeneration of bone and periodontal tissue. Regenerative endodontic procedures are widely being added to the current armamentarium of pulp therapy procedures. The regenerative potential of platelets has been deliberated. Platelet-rich fibrin (PRF) is a wonderful tissue-engineering product and has recently gained much popularity due its promising results in wound healing bone induction...

BACKGROUND/AIMS: Intermaxillary fixation is a standard procedure for the treatment of mandibular fractures or in orthognathic surgery. Pre-drilling for screws poses the risk of accidental tooth-root injury, potentially leading to further pathological processes. Limited evidence about accidental tooth injury during intermaxillary fixation is available due to heterogenous study designs. The aim of this study was to evaluate the risk of root trauma using pre-drilled transgingival fixation screws and the clinical consequences for the affected teeth...

: : Current treatment of periodontitis is still associated with a high degree of variability in clinical outcomes. Recent advances in regenerative medicine by mesenchymal cells, including adipose stromal cells (ASC) have paved the way to improved periodontal regeneration (PD) but little is known about the biological processes involved. Here, we aimed to use syngeneic ASCs for periodontal regeneration in a new, relevant, bacteria-induced periodontitis model in mice. Periodontal defects were induced in female C57BL6/J mice by oral gavage with periodontal pathogens...
