Effect of cigarette smoking on periodontal healing following surgical therapy

Preber, Hans, Bergström, Jan·1990·Journal of Clinical Periodontology

Abstract

Abstract The influence of cigarette smoking on the outcome of surgical therapy was investigated in 54 patients, 24 of whom were smokers. The patients had moderate to severe periodontitis with persisting diseased pockets after non‐surgical therapy. The surgical modality used was the modified Widman flap operation and the pockets under scrutiny were those with an initial probing depth of 4–6 mm. Re‐examination was made 12 months following the completion of surgery. The probing depth reduction at the 12‐month follow‐up was 0.76±0.36 mm (mean±SD) in smokers as compared to 1.27 0.43 mm in non‐smokers. The difference was statistically significant (P<0.001) and persisted after accounting for plaque. The results suggest that smoking may impair the outcome of surgical therapy.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
