Does smoking increase the incidence of postoperative complications in simple exodontia?

Abstract

To investigate whether smoking has adverse effects in simple exodontia. A single-centre, prospective study of postoperative inflammatory complications in simple exodontia was performed. All procedures were conducted under similar and sterile conditions. Postoperative complications (PCs) in exodontia were classified as alveolar osteitis (AO) or alveolar infection (AI) and their incidences then added. A logistic regression model for PCs revealed tooth sectioning [odds ratio (OR) = 4.3, 95% confidence interval (CI) 1.0-18.8; P = 0.050], smoking (OR = 4.5, 95% CI 1.0-18.9; P = 0.03) and amount of smoking (> 20 cigarettes/day: OR = 12.3, 95% CI 1.0-149.8; P = 0.04) to be associated with the occurrence of PCs. Tooth sectioning, smoking and degree of smoking are all associated with the development of PCs such as AO and AI after simple exodontia. Dentists must be alert to these factors when performing simple exodontia in smokers in view of the increased risk for PCs.
