牙周炎和龋病发病关系的初步分析

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。

Analysis of Pathogenic Relations between Dental Caries and Periodontitis

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.
