This study determines the effects of a routine assessment (Treatment as Usual, TAU) versus a risk communication intervention (Risk) versus a Goal-Setting, Planning and Self-Monitoring (GPS) intervention on periodontal disease patients' clinical and psychological outcomes.
In a three-arm randomized controlled trial (RCT; registration: ISRCTN59696243) adults (N = 97) judged to have moderate oral hygiene attended a primary dental care setting for a standard consultation. Intervention participants received an individualized calculation of their periodontal disease risk using only the Previser Risk Calculator (Risk group) or supplemented with a GPS-behavioral intervention (GPS group). Clinical, behavioral and psychological measures were obtained at baseline, 4 and 12 weeks later.
Percent plaque reduced significantly (P < 0.05) in intervention groups but not in TAU group. Percent of sites bleeding-on-probing reduced in all groups, but the effect was more pronounced in the intervention groups. Interdental cleaning frequency improved only in the intervention groups (P < 0.05). Brushing frequency and probing depths showed little variation across time/groups. Disease risk and most thoughts about periodontal disease changed across time (P < 0.05).
A simple behavioral intervention using individualized periodontal disease risk communication, with or without GPS, reduced plaque and bleeding and increased interdental cleaning over 12 weeks. This is the first study in the field to show that risk communication and behavioral techniques such as Goal-Setting, Planning and Self-Monitoring can improve periodontal outcomes.
本研究旨在确定常规评估（常规治疗，TAU）、风险沟通干预（风险）和目标设定、计划和自我监测（GPS）干预对牙周病患者临床和心理结局的影响。
在一项三臂随机对照试验（RCT；注册：ISRCTN59696243）中，被评估为口腔卫生中等的成年人（N=97）在初级牙科保健机构接受标准咨询。干预组参与者仅使用 Previser 风险计算器（风险组）或补充 GPS 行为干预（GPS 组）计算其牙周病风险的个体计算。在基线、4 周和 12 周后获得临床、行为和心理测量。
干预组的菌斑百分比显著降低（P<0.05），但 TAU 组无此变化。所有组的探诊出血百分比均降低，但干预组的效果更为明显。牙间清洁频率仅在干预组中得到改善（P<0.05）。刷牙频率和探诊深度在不同时间/组之间变化不大。疾病风险和大多数关于牙周病的想法随时间变化（P<0.05）。
使用个体化牙周病风险沟通的简单行为干预，无论是否使用 GPS，均可在 12 周内减少菌斑和出血，并增加牙间清洁。这是该领域第一项表明风险沟通和行为技术（如目标设定、计划和自我监测）可改善牙周结局的研究。
