This study aimed to investigate the periodontal condition when patients became self-responsible for the continuation of periodontal care, after non-surgical periodontal therapy and 2 years of Supportive Periodontal Therapy (SPT).
Fifty-seven patients completed a previous 2-year SPT study and were afterward advised to seek for dental assistance for maintenance care. After 4.2 ± 0.45 years of self-responsibility for periodontal care (SRPC), 27 patients could be re-examined of which 9 patients had followed the advice to turn to a dental professional for SPT care. Visible Plaque (VPI), Gingival Bleeding (GBI), Periodontal Probing Depth (PPD), Bleeding on probing (BOP), and Clinical Attachment Loss (CAL) were obtained from SPT study: before and after non-surgical treatment, and after 2 years of SPT. The same parameters were reassessed for the present study. General linear models for repeated measures were used for data analysis.
At the end of the SRPC period, mean GBI, BOP, and PPD values (43.5%, 55.7%, 2.76 mm, respectively) were back to pre-treatment, whereas VPI (64.3%) and CAL (3.76 mm) became significantly higher. The percentage of sites with PPD ≥5 mm as well as sites with CAL ≥4 or ≥5 mm also returned to pre-treatment values. However, the percentage of sites with PPD ≥4 mm was still significantly lower compared to pre-treatment values but higher than after 2 years of SPT.
Self-responsibility for the continuation of periodontal care after professional treatment should be avoided.
Clinicians and specialists must be conscious of making all efforts to maintain the patient's frequent recalls.
本研究旨在调查患者在接受非手术牙周治疗及两年的支持性牙周治疗（SPT）后，开始自行负责牙周护理延续时的牙周状况。
57名患者完成了之前为期两年的SPT研究，之后被建议寻求牙科协助进行维护治疗。在患者自行负责牙周护理（SRPC）4.2±0.45年后，对27名患者进行了复查，其中9名患者听从建议找牙科专业人员进行SPT护理。从SPT研究中获取了可见菌斑（VPI）、牙龈出血（GBI）、牙周探诊深度（PPD）、探诊出血（BOP）和临床附着丧失（CAL）的数据：非手术治疗前后以及SPT两年后。本研究重新评估了相同参数。采用重复测量的一般线性模型进行数据分析。
在SRPC阶段结束时，平均GBI、BOP和PPD值（分别为43.5%、55.7%、2.76mm）恢复到治疗前水平，而VPI（64.3%）和CAL（3.76mm）显著升高。PPD≥5mm的部位百分比以及CAL≥4或≥5mm的部位百分比也恢复到治疗前水平。然而，PPD≥4mm的部位百分比仍显著低于治疗前水平，但高于SPT两年后。
应避免患者在专业治疗后自行负责牙周护理的延续。
临床医生和专家必须意识到要尽一切努力确保患者定期复诊。
