【摘要】 目的:了解慢性牙周炎维护治疗期临床指标变化规律。方法:对牙周非手术基础治疗后进入维护治疗期的22名慢性牙周炎患者进行9个月的纵向观察。每3个月给予口腔卫生宣教,龈上下洁刮治和根面平整,并在基线和每次复查时记录临床检查指标,包括:探诊牙周袋深度(PPD)、探诊附着水平(PAL)和探诊出血(BOP)。结果:患者平均PPD减少0.44 mm,PAL增加0.38 mm,病情的好转主要集中在观察期的前3个月。4mm以上的牙周袋较浅袋更易随时间延长发生牙周袋深度增加,后牙较前牙有更多位点出现牙周袋加深。结论:非手术基础治疗配合定期维护,在较短观察期内可使大多数位点临床指标保持稳定甚至好转。更多还原

【Abstract】 Objectives:To investigate the characteristics of clinical changes during maintenance therapy of chronic periodontitis.Methods:22 patients with chronic periodontitis were enrolled in a 9-month maintenance care program after non-surgical periodontal therapy.Oral hygiene instructions together with supra-and sub-gingival scaling and root planing were carried out every 3 months.Clinical parameters including probing pocket depth(PPD),probing attachment level(PAL),and bleeding on probing(BOP) were recorded at baseline and each re-examination point.Results:The mean PPD decreased by 0.44 mm,PAL increased by 0.38 mm and BOP point number decreased by 18.94%.The recoveries were mainly observed during the first 3 months.Sites with ≥4 mm pocket at baseline exhibited a greater percentage of pocket deepening than those with initial shallow pocket.The incidence of the sites with PPD deeping of posterior teeth increased more than that of anterior teeth(P<0.005).Conclusions:Non-surgical periodontal treatment followed by regular maintenance therapy may stabilize or even improve the periodontal health in a short period.更多还原
