بررسي هيستولوژيك پالپ دندان در مبتلايان به بيماريهاي پريوزنتال

Introduction The close relationship between endodontics and periodontics is firmly established. Many authors claimed that pulpal inflammation may occur following periodontal diseases. The purpose of this study was histological evaluation of pulp in teeth with periodontitis. Materials & Methods 32 single root teeth with periodontal diseases and without any caries and restoration selected for extraction were used in this study. Extractions were done after special clinical and radiographical examination. Samples were fixed in 10% formalin and then decalcified by EDTA for three months. Six micron sections were prepared and stained by H & E. Pulp status was evaluated histologically under light microscope. Results Results showed that the amount of inflammatory cells was directly related with mobility and pocket depth. Atrophy in pulpal vessels as well as calcific feature were found in samples with deeper pocket. Conclusion The findings imply that pulp is significantly affected by periodontal disease. This should be a carefully considered factor when dental treatment is planned.
