Chronic periodontitis is one of the most frequent and severe diseases involving the tooth. Untreated, they can lead to tooth loss. Our study involved 67 patients with chronic marginal periodontitis who underwent tooth extraction, of which 29 had moderate periodontal lesions and 38 severe periodontal lesions. The microscopic study of the dental pulp revealed significant changes in all patients. In patients with moderate periodontitis the pulp tissue was found to be the site of an enhanced process of collagenous fibrosis associated with a moderate inflammatory infiltrate, dystrophic mineralization, reduced blood vascularization and arteriolosclerosis. The dental pulp of patients with severe periodontitis showed an abundant chronic inflammatory infiltrate associated with pulpal necrosis, vascular congestion, microhemorrhages, dentin demineralization and odontoblast impairment.

慢性牙周炎是涉及牙齿的最常见和最严重的疾病之一。如果不治疗,它们会导致牙齿脱落。我们的研究涉及67例接受拔牙的慢性边缘牙周炎患者,其中29例患有中度牙周病变,38例患有严重牙周病变。牙髓的显微镜研究显示,所有患者均发生了显着变化。在中度牙周炎患者中,发现牙髓组织是胶原性纤维化过程增强的部位,与中度炎症浸润,营养不良矿化,血液血管化减少和动脉硬化相关。严重牙周炎患者的牙髓显示出大量的慢性炎症浸润,与牙髓坏死,血管充血,微出血,牙本质脱矿质和成牙本质损伤有关。
