Numerical simulation of the biomechanical behaviour of multi-rooted teeth.
The elastic properties of the periodontal ligament (PDL) in eight multi-rooted teeth were examined in a combined experimental and numerical study in six minipigs. The initial tooth movement of the mandibular primary molars surrounded by the periodontium was registered three-dimensionally (3D) in an optomechanical measuring system. The dissections were then embedded in resin and cut in transvers...
متن کاملThree Rooted Primary Mandibular Molar – A Report of Three Cases
The dental literature contains a small number of reports of primary multirooted anomalies and even fewer reports on the clinical significance of these findings. Specifically, there are fewer reports of primary radicular anomalies than of permanent radicular anomalies. Knowledge of the size, morphology and variation of the roots and root canals of a primary tooth is useful in performing endodont...
متن کاملNasal teeth: report of three cases.
The ectopic eruption of the teeth into the nasal cavity is a rare phenomenon. We report cases: two involving the nasal cavity and one involving the hard palate and complicated by Aspergillus rhinitis. We describe the clinical and radiologic presentation of these cases and discuss their etiology, complications, diagnosis, and treatment.
متن کاملIn vitro comparison of dowel and core techniques for endodontically treated molars.
The restoration of broken down puIpless molar teeth generally implies the provision of a cast post and core with a crown. In this research the failure resistance of some restoration methods utilizing amalgam was investigated under an oblique load. The results suggest that intracoronal reinforcement with a prefabricated dowel did not significantly increase the in vitro resistance. It is expected...
