Because the database could not distinguish between re\u2010restorations and new restorations on the same teeth, follow\u2010up was initiated 6 months after the initial RC restoration. The follow\u2010up period continued until re\u2010restoration, censoring, or the end of a 2\u2010year observation period. A parametric mixed\u2010effects survival model was used, specifying hospital departments as the exposure variable. Hazard ratios (HRs) for re\u2010restoration were estimated, adjusting for confounders.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Among 103,595 teeth, 7942 (prevalence of re\u2010restoration\u00a0=\u00a07.7%, re\u2010restoration rate\/100 person\u2010year\u00a0=\u00a05.3) were reconstructed during 2 years.
