This case study reports the successful outcome of horizontal root fractures of two different patients, which took place in permanent incisors. Report 1 describes a case of a 29-year-old patient who suffered a mandibular trauma affecting mainly the lower central incisors, caused by a car accident. A panoramic radiograph was taken right after the accident and showed a horizontal root fracture in the middle third of tooth 42, which went untreated. Report 2 illustrates a case of a 17-year-old male patient who searched for orthodontic therapy and the periapical radiograph showed horizontal root fracture in tooth 11 caused by a previous trauma, which went untreated as well. There was healing through the reestablishment of pulp activity and dental coloration without professional intervention.

Incorporation of Carboplatin in Microporous Granular Calcium Phosphate Biphasic Matrix

引用

Journal of Biosciences and Medicines 2014年第2期2卷 30-35页

作者： cleomar Copatti N. H. A. Camargo E. Gemelli Chemistry Department Santa Catarina University Joinville Brazil Mechanical Engineering Department Santa Catarina University Joinville Brazil

The HA/β-TCP biphasic bioceramics stand out on researches in different areas of biomedical applications. These bioceramics with microporous microstructures also stand out in biomedical applications on controlled drug release. This study aimed at the synthesis of the biphasic HA/β-TCP powder, and at the elaboration and characterization of the microporous biphasic HA/β-TCP granular biomaterial. The microporous granular material was elaborated through the process of ceramic powder sieving (200 μm < d < 500 μm mesh sizes). The granular material was sintered at 1100°C/2 h, providing the microporous biphasic granular biomaterial. The drug loading in the biomaterial was performed through the high vacuum method. The results here presented are related to the synthesis method and elaboration of the biphasic biomaterial. The results obtained from the drug loading through the high vacuum method conducted the incorporation of the drug onto the surface and into the microporous granular biomaterial.
