The aim of this randomized controlled clinical trial was to determine the effects of single-visit full-mouth ultrasonic debridement versus quadrant-wise therapy.
Thirty-six subjects with chronic periodontitis, were randomly allocated to three groups--quadrant-wise ultrasonic debridement, single-visit full-mouth ultrasonic debridement with povidone iodine and single-visit full-mouth ultrasonic debridement with water. Whole-mouth plaque, bleeding on probing (BOP), pocket depth and attachment level were recorded before treatment and 1, 3 and 6 months post-treatment. Plaque and saliva samples were collected for microbiological analysis.
After treatment, all groups showed significant improvement in clinical parameters. Full-mouth treatments resulted in similar improvements in full-mouth mean plaque percentage, probing pocket depth and probing attachment level as conventional therapy. When data were analysed based on pocket depth and tooth type, there was no difference between groups in probing depth reduction or attachment gains. The full-mouth groups demonstrated greater reduction in BOP% and number of pockets > or =5 mm and the total treatment time was significantly shorter. The detection frequencies of periodontal pathogens in plaque and saliva showed slight changes with no difference between groups.
Single-visit full-mouth mechanical debridement may have limited additional benefits over quadrant-wise therapy in the treatment of periodontitis, but can be completed in a shorter time.
这项随机对照临床试验的目的是确定单次全口超声清创术与分象限治疗的效果。
36名患有慢性牙周炎的受试者被随机分为三组——分象限超声清创术、单次全口聚维酮碘超声清创术和单次全口水超声清创术。在治疗前以及治疗后1、3和6个月记录全口菌斑、探诊出血（BOP）、牙周袋深度和附着水平。收集菌斑和唾液样本进行微生物分析。
治疗后，所有组的临床参数均有显著改善。全口治疗在全口平均菌斑百分比、探诊牙周袋深度和探诊附着水平方面的改善与传统治疗相似。当根据牙周袋深度和牙齿类型分析数据时，各组在探诊深度减少或附着增加方面没有差异。全口治疗组在探诊出血百分比和深度≥5mm的牙周袋数量减少方面更为显著，且总治疗时间明显更短。菌斑和唾液中牙周病原体的检测频率有轻微变化，各组之间无差异。
在牙周炎治疗中，单次全口机械清创术比分象限治疗可能具有有限的额外益处，但可以在更短的时间内完成。
