Biocompatibility, Biomineralization and Induction of Collagen Maturation with t...

Biocompatibility and biomineralization of root canal dressings are important requirements for periapical healing. This study evaluated the inflammatory response, biomineralization and tissue repair by collagen fiber maturation in the subcutaneous tissue of rats. Eighteen Wistar rats (n = 6) received subcutaneous implants: calcium hydroxide + propylene glycol [CH+P], calcium hydroxide + propylene glycol + iodofo...

Evaluation of calcium hydroxide dressing for short term prevention of coronal l...

No. of bitstreams: 0 Previous issue date: 2010-01-01; Objective: The aim of this study was to compare two methodologies used in the evaluation of tissue response to root-end filling materials in rats. Material and Methods: Forty rats were divided into 4 groups: in Groups I and II (control groups), empty polyethylene tubes were implanted in the extraction s...

Late treatment of dental trauma using apexification technique

Made available in DSpace on 2022-04-29T15:50:16Z (GMT). No. of bitstreams: 0 Previous issue date: 2013-01-01; Introduction: A 37 years old male patient was admitted to the clinic of endodontics. After anamnesis it was found that the tooth #11 had coronary open access and the presence of calcium hydroxide with dental trauma history. Radiographically, the tooth had incomplete root formation, thin and fragile dent...

Evaluation of Fibronectin and Tenascin imunolabeling induced by bioceramic repa...

The aim of the study was to evaluate the presence of fibronectin and tenascin immunomarkers in the subcutaneous tissue of rats with Biodentine® bioceramic repair cement, when compared to White Angelus MTA® and Ca(OH)2. Polyethylene tubes were implanted in the subcutaneous tissue of 32 male Wistar rats containing the materials and an empty tube for control (n = 8 animals). After days 7, 15, 30 and 60, the animal...

Influence of viral infection in the healing process of periapical lesions: a na...

Background: Endodontic treatment aims to eliminate microorganisms and their toxic products, allowing the reestablishment of the host defenses and consequently, the healing of periapical tissues. However, numerous factors can affect periapical healing, such as the filling materials, the presence of microorganisms, systemic factors and, more recently, viral infections have been associated with the worsening of pe...

Evolutionary Leap in Endodontics. Case report

The Leap protocol combines the newest and most active association of reciprocal-rotary instrumentation, aluminum insert ultrasonic, and diode laser. The reciprocal-rotary technique consists of Niti instruments used in different motions depending on the stage of the treatment and promotes the balanced cutting effectiveness and reduced risk of fracture files. Moreover, it creates a centered and tapered shape. The...
