目的:探讨非外科牙周干预对口腔健康相关生活质量及牙周临床指标的影响。方法:91例重症慢性牙周炎患者分为治疗组(76例,给予非外科牙周干预)和对照组(15例,3%双氧水冲洗),年龄35~76岁,在初诊(T0)时测定牙龈指数(GI)、菌斑指数(PLI),探诊深度(PD)和附着丧失(AL),行中国版口腔健康影响程度量表14(OHIP-14,OHIP)和牙周健康自我评价表调查。在治疗后1个月(T1)、12个月(T2)再次测定GI、PLI、PD和AL,调查OHIP和口腔健康自我评价表。结果:患者OHIP分值为26.7±3.2,与年龄,口腔卫生和吸烟习惯密切相关。治疗组在T1和T2期OHIP分值及GI、PLI、PD、AL显著低于对照组(P<0.01)。治疗组OHIP分值在T1期(13.1±2.1)比T0期显著降低(P<0.01),OHIP分值在T2期(13.7±2.2)与T1期比无显著性差异;OHIP各条目分值及阳性反应患者比率在T1和T2期与T0期比较均明显降低,出现牙周健康有关症状患者比率在T1和T2期显著降低,GI、PLI、PD和AL与T0期比较有显著性差异(P<0.01)。PD>6 mm牙数所占比率在T2期(39.6%)明显低于T0期(65.5%)。结论:重症牙周炎与中国版OHIP显著相关,非外科牙周干预对口腔健康相关生活质量和牙周健康有关症状有明显改善作用。
Objective: To investigate the effect of non-surgical periodontal intervention on oral health-related quality of life and periodontal clinical parameters. Methods: Totally 91 patients with severe chronic periodontitis were divided into two groups: treatment group (76 cases, non-surgical periodontal intervention) and control group (15 cases, 3% hydrogen peroxide flushing) Gingival index (GI), plaque index (PLI), probing depth (PD) and attachment loss (AL) were measured. The Chinese version of OHIP-14, OHIP and periodontal health self-evaluation Table survey. GI, PLI, PD, and AL were measured again at 1 month (T1) and 12 months (T2) after treatment, and OHIP and oral health self-assessment questionnaire were investigated. Results: The OHIP score was 26.7 ± 3.2, closely related to age, oral hygiene and smoking habits. The scores of OHIP, GI, PLI, PD and AL in T1 and T2 phases in treatment group were significantly lower than those in control group (P <0.01). The scores of OHIP in the treatment group were significantly lower than those in the T0 phase (P <0.01) at T1 (13.1 ± 2.1), OHIP scores were not significantly different at T2 (13.7 ± 2.2) and T1 The proportion of patients with positive reaction decreased significantly at T1 and T2 compared with that at T0, and the rate of periodontal health-related symptoms decreased significantly at T1 and T2. There was significant difference between GI, PLI, PD and AL at T0 <0.01). The proportion of teeth with PD> 6 mm was significantly lower in T2 (39.6%) than in T0 (65.5%). Conclusion: Severe periodontitis was significantly associated with Chinese version of OHIP. Non-surgical periodontal intervention significantly improved oral health-related quality of life and periodontal health-related symptoms.
