To assess risk factors for alveolar osteitis.
A prospective nested case-control study was conducted in an urban community dental clinic in Valdivia, Chile. A cohort of 1,355 patients who underwent dental extractions was included. Eight predictor variables (risk factors), namely patient gender, hygiene, tooth location, previous surgical site infection, traumatic extraction, systemic diseases, alcohol consumption, and tobacco use, were considered in a risk factor model. A binary regression logistic analysis was performed to determine significant associations.
In total 1,302 participants completed the follow-up. Eighty incident case patients with alveolar osteitis and 80 matched control patients were included. A statistically significant association was found between traumatic extraction (odds ratio [OR], 13.1; 95% confidence interval [CI], 5.4 to 31.7), tobacco smoking after extraction (OR, 3.5; 95% CI, 1.3 to 9.0), previous surgical site infection (OR, 3.3; 95% CI, 1.4 to 7.7), and the development of alveolar osteitis.
Previous surgical site infection, traumatic extraction, and tobacco smoking are associated with an increased risk of alveolar osteitis.
评估牙槽骨炎的危险因素。
在智利瓦尔迪维亚的一家城市社区牙科诊所进行了一项前瞻性巢式病例对照研究。纳入了1355例接受拔牙的患者队列。在一个危险因素模型中考虑了八个预测变量（危险因素），即患者性别、口腔卫生、牙齿位置、既往手术部位感染、创伤性拔牙、全身性疾病、饮酒和吸烟。进行二元回归逻辑分析以确定显著关联。
共有1302名参与者完成了随访。纳入了80例牙槽骨炎发病病例患者和80例匹配的对照患者。发现创伤性拔牙（比值比[OR]，13.1；95%置信区间[CI]，5.4至31.7）、拔牙后吸烟（OR，3.5；95%CI，1.3至9.0）、既往手术部位感染（OR，3.3；95%CI，1.4至7.7）与牙槽骨炎的发生之间存在统计学显著关联。
既往手术部位感染、创伤性拔牙和吸烟与牙槽骨炎风险增加相关。
