牙周炎和龋病发病关系的初步分析

Analysis of Pathogenic Relations between Dental Caries and Periodontitis

目的深化牙周炎和龋病的病因认识。方法短时间(1a)内在口内初诊成人(18～50岁)中,选择重度慢性牙周炎(CP)患者70例和龋敏感(CS)患者50例,检查CP组患者的牙体龋坏情况及CS组患者的牙周状况,探讨牙周炎和龋病两者发病的关系。结果CP患者口腔中确实少有龋齿,CP和CS组的龋齿指数(DFS)分别为1.46±2.60和17.32±7.55(P<0.001);CS患者的牙周情况较好,CS和CP组的牙周治疗需要指数(CPTNI)分别为0.98±0.63和3.24±0.62(P<0.001),CS和CD组的失牙数无显著差别,分别为1.90±3.34和1.10±1.85。仅发现3例患者(2.4%)既符合CS又符合CP组条件。结论:牙周炎和龋病的发病可能有对抗倾向,两者生态联系和相互影响值得深入研究。

Objective In order to search the cause of dental caries and periodontitis. Methods Selected 70 patients with severe chronic periodontitis (CP group) and 50 patients with caries sensitivity (CS group) in clinical adults of oral medicine (18 to 50-year-old) during 1 year. Parameters of oral hygiene, caries and periodontitis were recorded in the typical groups of CP and CS. Results The patients of CP group had rare caries, DFS in the groups of CP and CS was 1.46±2.60 and 17.32±7.55 respectively(p<0.001),while the patients of CS group had relative periodontal health indeed,CPTNI in CS and CP groups were 0.98±0.63 and 3.24±0.62 respectively (p<0.001),and the number of missing teeth was 1.90±3.34 and 1.10±1.85 respectively(p>0.05). 3 patients(only 2.4%)confirmed the parameters of caries sensitive as well as severe periodontitis. Conclusion The correlating pathogenesis of caries and periodontitis seems to have antiagonism tendency. The ecological connection and bacterial interaction are worthy of further study.
