一次性全口龈下刮治和根面平整术治疗慢性牙周炎的近期疗效评价

目的：探讨一次性全口龈下刮治和根面平整术（full-mouth scaling and root planning，FM-SRP）治疗慢性牙周炎的效果，并与常规的分象限刮治（quadrant scaling and root planning，Q-SRP）效果进行比较。方法：将60例慢性牙周炎患者随机分为2组：FM-SRP组在1天内完成全口所有象限的刮治和根面平整。而Q-SRP组每周进行1个象限的刮治，连续4周完成全口治疗。分别在基线、3个月和6个月时，检测菌斑指数（plaque index，PI）、牙龈指数（gingival index，GI）、探诊出血（bleeding on probing，BOP）、探诊深度（probing depth。PD）及附着丧失（attachment loss，AL）的变化及患者的术后反应。所得结果分别进行秩和检验（PI、GI）、t检验（PD、AL）和X^2检验（BOP）。结果：与基线时相比，2种治疗方式在3个月和6个月时的所有临床牙周指数均有显著改善（P〈0．01），但2组之间无显著性差异（P〉0．05）。在首次治疗24h，FM-SRP组的术后反应发生率显著高于Q-SRP组（P〈0.05），但患者能够耐受。结论：FM-SRP和Q-SRP两种方法均可达到相同的临床效果，临床医生可根据实际需要，选择合适的治疗方式。

The clinical effect of full-mouth scaling and root planning on chronic periodontitis: A preliminary report

PURPOSE: To explore the clinical effect of full- mouth scaling and root planning (FM- SRP) on chronic periodontitis with the comparison of quadrant scaling and root planning (Q- SRP). METHODS: 60 patients with chronic periodontitis were randomly divided into 2 groups. The FM- SRP group received full- mouth scaling and root planning completed within the same day, while the Q- SRP group received quadrant scaling and root planning once a week for 4 weeks. Clinical parameters of plaque index (PI), gingival index (GI), bleeding on probing (BOP), probing depth (PD) and attachment loss (AL) were collected at baseline, 3 and 6 months after treatment, as well as the postoperative reaction. The data were analyzed by rank sum test(PI,GI), t test(PD,AL) and Chi square test(BOP), respectively. RESULTS: When compared with the baseline, both therapies resulted in significant improvements in all clinical parameters at the end of 3 and 6 months(P<0.01). However, there were no significant difference between the two groups at any time point( P>0.05). 24 hours after the first treatment, the percentage of patients with postoperative reactions were significantly higher in FM- SRP group than that in Q- SRP group(P<0.05), but the patients could tolerate these reactions. CONCLUSION: Both FM- SRP and Q- SRP are efficacious in treating chronic periodontitis, and the clinician can select the proper treatment modality according to the demand of clinical practice.
