Several longitudinal studies have explored the association of obesity and weight gain with periodontal disease. However, the effect of weight loss on periodontal tissues remains unclear.
To explore whether weight loss after bariatric surgery was associated with changes in periodontal measures over 12 months.
Two public hospitals in São Paulo, Brazil.
We used data from 110 morbidly obese patients (body mass index [BMI]>40 kg/m or≥35 kg/m with co-morbid conditions) who underwent bariatric surgery between April 2011 and March 2013. Data on demographic factors, BMI, smoking habits, and glucose levels were extracted from medical records preoperatively and after 6 and 12 months postsurgery. A full-mouth periodontal examination was conducted by trained examiners to assess probing pocket depth, clinical attachment loss, and bleeding on probing (BOP) at baseline and 6 and 12 months after surgery. Data were analyzed using linear mixed-effects models.
BMI was not significantly related to the proportion of sites with BOP at baseline, but it was negatively associated with the rate of change in the proportion of sites with BOP. The greater the BMI loss, the higher the proportion of sites with BOP, particularly 6 months after surgery. However, BMI was not associated with baseline probing pocket depth and clinical attachment loss or rates of changes in these periodontal outcomes.
The findings suggest that weight loss was associated with increased gingival bleeding, showing a peak at 6 months after bariatric surgery. Periodontal pocketing and attachment loss remained unchanged during the study period.
多项纵向研究探讨了肥胖和体重增加与牙周疾病之间的关联。然而，体重减轻对牙周组织的影响仍不明确。
探讨减肥手术后体重减轻是否与12个月内牙周指标的变化相关。
巴西圣保罗的两家公立医院。
我们使用了2011年4月至2013年3月期间接受减肥手术的110例病态肥胖患者（体重指数[BMI]>40kg/m或≥35kg/m且伴有合并症）的数据。术前以及术后6个月和12个月时，从病历中提取人口统计学因素、BMI、吸烟习惯和血糖水平的数据。由经过培训的检查人员进行全口牙周检查，以评估基线时以及术后6个月和12个月时的探诊袋深度、临床附着丧失和探诊出血（BOP）情况。使用线性混合效应模型对数据进行分析。
BMI与基线时BOP部位的比例无显著相关性，但与BOP部位比例的变化率呈负相关。BMI降低幅度越大，BOP部位的比例越高，尤其是在术后6个月时。然而，BMI与基线探诊袋深度和临床附着丧失或这些牙周指标的变化率无关。
研究结果表明，体重减轻与牙龈出血增加有关，在减肥手术后6个月时达到峰值。在研究期间，牙周袋深度和附着丧失保持不变。
