OBJECTIVES
We evaluate oral health conditions before and after bariatric surgery.
METHODS
The sample was composed of 59 patients who had undergone Roux-en-Y gastric bypass (RYGB). Salivary flow, periodontal pocket depth and dental wear were evaluated before and after 6 months of surgery. Body mass index (BMI), C-reactive protein (CRP) and glucose levels were obtained from the patient's medical files. A t-test was used for dependent samples.
RESULTS
The mean BMI decreased from 49.31 ± 8.76 to 35.52 ± 8.12 kg/m(2) in 6 months after surgery (P < 0.000). Before surgery, 67% of patients had high levels of CRP and 38% higher blood glucose levels and after surgery there were significant reductions in these levels (P < 0.001). Salivary flow ranged from 0.84 to 0.95 ml/min. There was increased prevalence of periodontal pockets (P = 0.022) and mean pocket depth increased to about 0.5 mm (P < 0.001). The percentage of surfaces with dental wear in dentine was significantly higher after bariatric surgery (P = 0.002), while dental wear in enamel decreased (P = 0.019).
CONCLUSIONS
Bariatric surgery may improve systemic conditions. However, it had a negative impact on oral health conditions because of an increase in periodontal disease and dental wear.
目的
我们评估了减肥手术后的口腔健康状况。
方法
样本由59例接受了Roux-en-Y胃旁路术（RYGB）的患者组成。在手术前及术后6个月评估唾液流量、牙周袋深度和牙齿磨损情况。从患者的病历中获取体重指数（BMI）、C反应蛋白（CRP）和血糖水平。使用配对样本t检验。
结果
术后6个月，平均BMI从49.31±8.76降至35.52±8.12kg/m²（P<0.000）。手术前，67%的患者CRP水平高，38%的患者血糖水平高，术后这些水平显著降低（P<0.001）。唾液流量在0.84至0.95ml/分钟之间。牙周袋患病率增加（P=0.022），平均袋深度增加约0.5mm（P<0.001）。减肥手术后牙本质出现牙齿磨损的表面百分比显著更高（P=0.002），而牙釉质的牙齿磨损减少（P=0.019）。
结论
减肥手术可能改善全身状况。然而，由于牙周疾病和牙齿磨损增加，它对口腔健康状况有负面影响。
