摘要
对60例慢性牙周炎患者18个月的支持治疗期进行回顾性研究,参照牙周风险评估系统(PRA)提供的复诊时间,其中规律复诊者(RC)23例,不规律复诊者(EC)37例,比较两组失牙数、探诊深度、探诊出血率和复发危险度的变化。结果显示RC组疗效较好,表现为未失牙,EC组失2颗牙;RC组探诊深度平均减少1.11 mm,EC组减少0.80 mm;RC组探诊出血率平均减少42.72%,EC组减少34.10%;RC组21.7%的患者由高复发危险度变为中复发危险度,EC组为13.5%。RC组的探诊深度和探诊出血率比EC组改善明显(P<0.05)。
As a retrospective study,periodontal risk assessment（PRA） was performed in 60 patients with chronic periodontitis for 18 months of supportive periodontal therapy（SPT）.Referring to the referral time the PRA provided,23 regular complier（RC） and 37 erratic complier（EC） subjects were selected.The change of tooth loss,probing depth,the rate of bleeding on probing and the degree of risk recurrence between the RC and EC were compared.During SPT,the RC group showed better curative effect：0 tooth was lost in RC and 2 teeth in EC;Probing depth decreased 1.11 mm on average in RC and 0.80 mm in EC;The rate of bleeding on probing decreased 42.72% on average in RC and 34.10% in EC;21.7% of patients with high risk of recurrence became to be moderate risk of recurrence in RC and 13.5% in EC,that is,probing depth and the rate of bleeding on probing in RC exhibited significant improvement compared with EC（P0.05）.
