The aim of this retrospective analysis was to investigate how smoking cessation impacts the results of non-surgical periodontal therapy in patients diagnosed with periodontitis. Additionally, the analysis sought to determine the percentage of patients who quit smoking after receiving cessation counselling before undergoing non-surgical periodontal therapy.
This retrospective analysis looked into potential links between smoking cessation and treatment outcomes, as well as the impact of gender and age. For the analysis, data from the periodontal charts of smoking patients who were referred to the Clinic for Periodontology Utrecht for moderate to severe periodontitis between 2019 and 2022 were utilised. Demographic and clinical information was collected from both intake and evaluation appointments, and the percentage of patients who stopped smoking was assessed. For each patient, the total number of teeth (excluding implants), the percentage of teeth and sites with a pocket probing depth (PPD) > 5 mm, and the percentage of sites with bleeding upon probing (BOP) were identified.
The current retrospective analysis included a total of 143 patients, out of which 24 patients (17%) quit smoking after receiving cessation counselling before non-surgical periodontal therapy. However, no significant difference was observed for percentage teeth and sites with PPD > 5 mm and percentage BOP between patients who quit smoking and those who continued smoking at the evaluation stage. This indicates that smoking cessation did not significantly impact the outcome of non-surgical periodontal therapy. Sub-analysis showed no relation between age and the effect of smoking cessation on the results of non-surgical periodontal therapy. However, for patients over the age of 50, the number of teeth at evaluation was lower than those ≤ 50 years (24.7 vs. 26.5, respectively, p < 0.001). Sub-analysis on gender showed that male quitters had a significantly lower number of pack-years than those who continued smoking (10.4 vs. 20.4, respectively, p = 0.04). Comparison of males and females showed no significant differences.
In this retrospective analysis, overall, no significant effect of smoking cessation on the outcome of non-surgical periodontal therapy at the evaluation appointment has been found. Sub-analysis showed that neither age nor gender had a significant effect on the results of non-surgical periodontal therapy. For male gender, the number of pack-years seems to impact on the intention to quit smoking.
本回顾性分析旨在研究戒烟如何影响被诊断为牙周炎患者的非手术牙周治疗效果。此外，该分析还试图确定在接受非手术牙周治疗前接受戒烟咨询后戒烟的患者百分比。
本回顾性分析研究了戒烟与治疗结果之间的潜在联系，以及性别和年龄的影响。分析时，使用了2019年至2022年间转诊至乌得勒支牙周病诊所治疗中度至重度牙周炎的吸烟患者牙周图表中的数据。从初诊和评估预约中收集人口统计学和临床信息，并评估戒烟患者的百分比。对于每位患者，确定牙齿总数（不包括种植体）、牙周袋探诊深度（PPD）>5mm的牙齿和部位的百分比，以及探诊出血（BOP）部位的百分比。
本次回顾性分析共纳入143例患者，其中24例（17%）在接受非手术牙周治疗前接受戒烟咨询后戒烟。然而，在评估阶段，戒烟患者与继续吸烟患者之间，PPD>5mm的牙齿和部位百分比以及BOP百分比均未观察到显著差异。这表明戒烟对非手术牙周治疗的结果没有显著影响。亚分析显示年龄与戒烟对非手术牙周治疗结果的影响之间没有关联。然而，对于50岁以上的患者，评估时的牙齿数量低于50岁及以下的患者（分别为24.7颗和26.5颗，p<0.001）。性别亚分析显示，男性戒烟者的吸烟包年数明显低于继续吸烟者（分别为10.4和20.4，p=0.04）。男性和女性的比较未显示出显著差异。
在本次回顾性分析中，总体而言，未发现戒烟对评估预约时非手术牙周治疗结果有显著影响。亚分析表明，年龄和性别对非手术牙周治疗结果均无显著影响。对于男性而言，吸烟包年数似乎会影响戒烟意愿。
