Mineral Trioxide Aggregate is a material developed for endodontics that appears to be a significant improvement over other materials for procedures in bone. It is the first restorative material that allows for the overgrowth of cementum and the regeneration of periodontal ligament. The present case report illustrates the use of MTA in treating a case of perforation in the furcation area with lo...

The purpose of this study was to compare the clinical, radiographic, and histo[ogic changes that occur in response to three of the most commonly used materials to repair furcation perforations. The results of the experiment showed that amalgam was superior to Cavit and calcium hydroxide as a sealing material of furcation perforations. The most severe reactions occurred in the control group wher...

The aim of this in vitro study was to measure critical morphology of molar pulp chambers. One hundred random human maxillary and mandibular molars (200 teeth in total) were used. Each molar was radiographed mesiodistally on a millimeter grid. Using a stereomicroscope, the measurements were read to the nearest 0.5 mm. Results were as follows (mean, mm): pulp chamber floor to furcation, maxillary...
