Few prospective studies have reported the effects of periodontal therapy on patients who attempted to quit smoking. This study aimed to assess how smoking cessation affects periodontal therapy. Twenty-five smokers with periodontitis were investigated by dividing them into two groups, a smoking cessation support group and a continued smoking group. Those in the support group received counseling and nicotine replacement therapy, followed by periodontal treatment conducted by dentists who had completed an e-learning course on smoking cessation. Clinical parameters were measured at baseline, 3, and 6 months. Most clinical parameters improved for those in the smoking cessation support group. There were no significant improvements in bleeding on probing (BOP) or the number of severe periodontal disease sites in the continued smoking group. Probing pocket depth (PPD) and clinical attachment levels (CAL) at sites that received scaling and root planing (SRP) significantly improved in all subjects. BOP did not improve at reevaluation in the smoking relapse subgroup. Patients in the smoking cessation support program led by dental professionals showed more improvement in BOP than those in the continued smoking group.

很少有前瞻性研究报道过牙周治疗对尝试戒烟患者的影响。这项研究旨在评估戒烟如何影响牙周治疗。将25名患有牙周炎的吸烟者分为两组，分别是戒烟支持组和持续吸烟组。支持小组的人员接受了咨询和尼古丁替代疗法，然后由完成了戒烟电子学习课程的牙医进行了牙周治疗。在基线，3个月和6个月时测量临床参数。对于戒烟支持小组中的大多数人来说，大多数临床参数都有改善。持续吸烟组的探查出血（BOP）或严重牙周疾病部位数量没有明显改善。在所有受试者中，在接受结垢和根部平整（SRP）的部位进行探查袋深度（PPD）和临床附着水平（CAL）均得到明显改善。重新评估吸烟复发亚组的BOP没有改善。由牙科专业人员领导的戒烟支持计划中的患者与持续吸烟组相比，其BOP改善更大。
